Well we have one of these for camping stuff and cycling stuff. Have you bought any IT sort of stuff today?

I'll start. 2GB RAM Chip for my netbook

Ooh, good thread.

I note that all the cycling and camping are getting in the way of my computing habit.

Not today, but Sunday past. Cheap(ish) 7" Android tablet (PC* World stock No 003926 if yer interested)  to use as a testbed whilst I get to grips with writing Android apps.  On which subject; my my hasn't Eclipse changed enormously since 2000?

Still waiting for 4GB of RAM for this box so that Eclipse and the AVD don't run quite so slowly.


*Yes, I know I could have got better & cheaper on-line, but Swindon PC world is only a short cycle ride away and I hadn't cycled from Lechlade to Swindon since 1999 or 2000.

Oh and the cash machine at Greenbridge is no longer free. *Grumble*

Not today, but yesterday, and I have only just remembered (as I have had an email informing me of dispatch) a Intel Atom based box to replace BigBlue, our filesharing server (hosts our photos, music and video here in the dragon's lair).

To be fair, it's about 4 years overdue as Bigblue was originally built out of spare bits I had lying around, then the motherboard and graphics card were replaced about 2 years ago when it all went horribly wrong, it's still based around a P4 2.8 Ghz dual core from thousand and *cough*cough*.

Hopefully the new one will do all that the old one did, but drink less electrons whilst doing it....

A large pile of bits, notably an Ivy Bridge Core i5 and all the requisites for making it go.

My first self-built machine for some years (having been living mostly in the Apple RDF).  On the whole, it went together pretty smoothly, with far fewer sharp case-edges and troublesome AGP cards than I remember from my previous DIY 'puter.

Ubuntu Unity may take some getting used to (and/or replacement...).

Just recieved a 2TB HDD, which I've installd in my Vu+ Ultimo HD sat box, which replaces the sky box.
This enables the pause-TV function, and recording in general.

This box (dreambox type thing ) allows me to card-share my sky subscription to other client devices in the house ( and beyond! )
So no more fights between the kids about what sky channel to watch.

Also Mountain Lioned my MacBook – took an age to download (4GB) but installed quickly and smoothly. Common to many recent MacOS upgrades I had to check it had actually worked, it looks much the same. Not a complaint, I like the incremental approach, rather than the WHERETHEFUCKHASEVERYTHINGGONE. Desktop OSs are mature. Treat them as such.

No bugs noted, everything seems to work. It didn't like an old version of Parallels, but I'd moved to Virtualbox anyways, so it just reminded me to remove it.

Some nice bits of polish really but it's not going to shake the average Mac user's world. I'm still not sold on iCloud – like the concept, but not the Apple implementation, I much prefer Dropbox. They should also hunt the person down adding the stupid 'skins' for Calendar, Notes etc. and kill them before they inflict more pain on my eyes. Really, I don't need the visual metaphor, just make them look like other MacOS applications.

Finally got around to purchasing NAS and backup systems - last week.

See earlier post for history: http://yacf.co.uk/forum/index.php?topic=56833.0 (http://yacf.co.uk/forum/index.php?topic=56833.0)

So a pair of each of the following:
Synology DS212 twin bay NAS box (with USB3.0 outputs and WOL activation)
WD RE4 500Gb SataII 64Mb (5003ABYX) HDDs to fit into NASes.
WD "My Passport" 500Gb PHD (USB3.0 inputs) - encryptable for sensitive data NAS"A" backups
WD "elements" 500Gb PHD (also USB3) for backup of non-sensitive data/music/photos/OS files from NAS"B".

Just got to fit the HDDs, configure the system(s) then workout how to WOL with my deskie/lappie when my PV generator is producing some free juice  :)

[edit] Corrected the specs when I got home.
I went for the SATA II HDDs at 64Mb as being quoted by Synology as being compatible. I could have gone for Sata III alternatives but the Synology info couldn't clarify on compatibility. The SATA IIs were £62 each for 500Gb 3.5" drives. SATA IIIs at 64Mb buffer were listed at around £83 each. So, I went for the stated SATA II versions. HDD costs have dropped nicely since I first looked at such systems 12 months ago.
The encryptable PHDs were £60 each. The standard PHDs were £50 each.[/end edit]

Funnily enough, Amazon delivered the NAS, HDDs and Passport PHDs within 2 days (all arriving within 10mins of each other from different suplliers!).
But the other 2 PHDs I ordered from Currys - cheapest BION! 'Coz I was off work recovering from minor op, I went for home delivery option. Expected on Wed!
Now I'm allowed to drive so back at work, it would have been easier to wait, then buy the d*mn things one evening... ::-)

[edit]
My thanks to those of you who responded in my OP and gave advice leading to these purchases. I only need a simple weekly backup system so have saved myself from the joys of 24/7 RAID options, overly large HDDs and failure risks, which I might otherwise have blindly strayed into. Again, thanks to you all!  :thumbsup:

Next purchase will be a Logitech Squeezebox Touch once I've FLAC'd a load of my CD collection...

Title: Re: Bought any computing stuff today?

I bought a floor cable protector and a rug so I do not need to look at the cable protector.

All part of my big, not quite right, home cinema project.  All I want is better sound than I get from the computer when watching dvds.  On one side of my bedroom I have a proper hifi (Audiolab amp, tuner and cd/dac; Mission speakers).  In one of the far corners sits my computer it has decent for a computer speakers but £100 Sony speakers from a motherboard sound chip was clearly not as good as the ~£3,000 hifi.  Recently my old cd player stopped working and the Audiolab cd/dac was added.  I noticed that this had a couple of TOSLink sockets The tuner's DAB output was immediately connected to one (better DAC in the CD),  I then decided to connect the computer.  So I buy a 7.5m cable and discover for the over the door route it was too short. To make matters worse when I connected it up to the computer I looked at the software to use the optical socket I discovered it was an input. More money required.  I buy a 10m cable and route around the room and over the door. I also buy an ASUS Xonar Esscence sound card which has audiophile pretensions and an optical output.  First I connect the computer speakers. This is a big improvement in sound quality.  Then I connect the hifi and another improvement in sound quality. 

I decide the cable over the door looks ugly so decide to use the under the bed and across the floor route.  So the 10m cable will be used elsewhere sometime.  The short area between my bed and hifi would create an ugly trip hazard so a rug to please the eye and a cable protector to prevent damage when feet are placed on it.
 
Next step is a big telly above the hifi and a hdmi cable from the computer. I think I will wait to the new year before doing that.  In my experience domestic electrical goods are cheapest in early February after the January sales.

Said picoITX psu arrived.

Said picoITX PSU can't provide enough juice to power an Atom MB.

New 160W picoITX and laptop brick ordered from Logic Supply in The Netherlands.

Fingers crossed for this one, in the meantime, does anyone need a 90W picoITX PSU, only used for about 5 mins until I realised that it's just not got enough grunt?

A 2 GB HDD for Junior's PC, since he has used Steam (yuk! ) to fill his old one to capacity with various shoot-em-up games.

Imaging-fest later in the week.

And a 2GB external USB drive to make image backups of Mrs F's laptop, which is used for work etc.
We had a bit of an incident a few months ago, which came close to nuke from orbit, and this was not a happy option.
So I did promise to do some image-based backup on it.

So another image-fest.

I just bought another 3TB HDD for the file server as I continue my quest to get all my DVDs ripped for streaming (It now has 9TB of disk space and room for one more  :thumbsup: ).
I'm wil be sending my venerable workstation into retirement this week - 5 years of flawless service but it isn't getting used and the space will be useful. Also a couple of external disk drives (160GB and 300GB) have been pensioned off - free to good home if anyone is interested.

As part of my on going multimedia / mid level home cinema project I bought a new video card Sapphire 7750 Ultimate.  This is a passively cooled card and is a little faster than the HIS ICEQ 5670 it replaced.  In the gloom under my desk I thought the HIS didn't have a hdmi socket, it does. I also bought a Hauppage hvr-440 tv tuner card. 

Fitting was not so easy. I did not think about the oversize heat sinks that come with passive graphics cards. I removed the old card but the new card could not fit in the space slot 1 (pci-e x16) and 2. Slot 0 (pci-e x1) was occupied by the full height sound card. The heat sink needed that space.  So the sound card came out and was moved to slot 3 (pci-e x1).  Fortunately the tv card was low profile and was put in slot 0. Everything fitted phew.  I have a pci-e x16/8 and one of my two pci slots spare, the other contains my scanner's scsi card. I used to think I would hardly use the expansion slots on a modern pc.

Switch it on, Windows XP comes up in VGA mode and messes up my icons. I hadn't updated my video driver so they were too old to recognise the 7750.  I installed the proper driver and the screen was returned to 1920x1080.  I then fed the system the Hauppage cd and all the exclamation marks disappeared from device manager. The sound card was also upset being moved but found its drivers and carried on.  I discovered that Power Dvd will not play sound through my sound card with its optical connection to my hifi when the hdmi sound driver is installed.  The hifi does not speak hdmi until the 8200ap AV preamplifier and 8200p power amplifier arrive on Saturday.

To buy nice TV.
To buy good blu ray player.
To buy high quality hifi speakers and matching centre speaker and another power amplifier.
To buy sub woofer

A lot of money.  A top end plastic bike price.

An HP Designjet 111 printer!  Eek, thats big!  It'll enable me to actually print the drawings I produce...  It was delivered by a very nice and helpful Parcelforce man (never thought I'd hear myself saying that) who came back for a second attempt at delivery as I was out in the morning (cos we wuz driving back from Wales)  That said, he probably didn't want to try to heave it out of the van on his own, so hoped I'd be in to help relieve him of the monstrous thing.

Unlike the last HP product I bought, it actually seems to work.  The auto paper cutter is vaguely scary...

Hooked it up to a Vigor 120 modem and all was good - line retrained from 6503571 to 7154016 on connection (still only 20CN here). A quick test with speedtest.com gave me my best ever download rate (6.93Mb/sec up from around 6.3). Firewall needed a bit of tweaking to get stuff through to the server but that was it.
Next up - native IPv6. Getting tempted with the thought of a second line as the Firebrick will do line bonding (goes away to count the pennies...)

Dual stack ipv4/ipv6 up and running. radvd running on the server sorting out ipv6 addresses for the network and my DNS server doing forward lookups. reverse lookups still to do. All OSX/Linux here and they all seem to be playing nicely and now ignoring ipv4 between themselves  :thumbsup:
The only thing I'm not quite understanding at the moment is the way A & A have set up subnets - some could be deleted but I can't quite grasp which ones.
I need to have a word with A & A as I appear to have a /64 block and 2 x /48 blocks allocated to me - I probably have enough addresses for the entire population of Scotland  :o

A friend has donated a USB keyboard and mouse!

So have some time to try setting up an SD Micro card with Raspbian (or, if unsuccessful, just order one) before Christmas, so I can learn enough myself to shepherd 10-year-old grandson into using it without too much pain and sweat.

Have you used a Linux based machine before? Expect the desktop to be sluggish, use it on an HDMI screen, not a RCA video (which really sucks) and it should be OK.

Mine are fine for their embedded usages.  Wireless can be interesting but there are enough people around here who can help if you have questions.

Thanks, David.  I have used  Vector Linux (http://www.vectorlinux.com) for a number of years, so have the rudiments.  But I thought in the meantime, while waiting for it to arrive, I would experiment with Debian (upon with Raspbian is based).

I'll be sure to ask on here if I get stuck.

The thing that really got my youngest's attention was the arduino reaction tester. A multicolour led that changes colour, then as soon as it goes out you hit your button. Green for one side, red for the other and a bit of cheat catching too..

Have to recreate that for the Pi. It involved an LCD screen on which the reaction time was displayed.

A new laptop.

Now, being a skinflint I declined to pay £5 extra for it to be delivered tomorrow (to work). Which is when I go to work on the bus.

So it might arrive on Friday. Which is when I cycle. 

bah. Should have just paid the £5 extra!

Edit
Arrivee!

Last Wednesday, I ordered a couple of RPis for home - there'll be squabbles if we don't have one each  ::-)  - Based on other people's notes, I was expecting a few weeks wait, but they arrived on Saturday.

Now, if I could only get rid of this hacking cough and the snot, I would have the mental capacity to play with one, but so far all I've had the brain to do is fire one up and check it works.   >:(

That shouldn't kill it. They must have seriously cut some corners in the circuits, left off protective caps and resistors.

The dev boards I use get live disconnects/connects over GPIO pins all day long and it doesn't do damage.

Even so - it shouldn't blow the board.

Sticking 12V in over a 5V line might blow things.

I believe that's exactly what they did, to keep costs down (lots of people won't use the GPIO).  Hence all the recommendations to add buffering if you're going to be mucking about on breadboards.

There's also a health warning about powering the Pi via the 5V pin on the GPIO header.  Works fine, but bypasses the protection on the micro-USB connector.

Precisely - I do have a Gertboard too but wasn't using it, and hurrying to finish the project because i was getting hassled to do something else. At least it was £30 worth of raspi not a couple of grands worth of Mac I was messing about with.

Laptop HDD has died, so decided to replace it with a SanDisk 128GB SSD.  I'm running low on storage so ordered a WD 2TB Caviar Green HDD.  Finally, picked up a Kingston 16GB 'Data Traveller' with the intention of setting up a bootable USB drive.

I've lost some downloaded BBC programmes from the laptop, but all important stuff was recently backed up.  Shouldn't take me much more than an hour to get that up and running again.  The 2TB HDD is a second drive for my file server - hoping getting the system to recognise it won't be too much of a problem.  I will eventually set up a NAS, but not until later in the year.  The USB drive is just something to play around with.

HP LaserJet Pro 400dw to replace my venerable old Laserjet 4 that died at the weekend. I can't even remember just how long I've had the old printer but it replaced an Epson dot matrix purchased in the 80's - 2 printers in around 30 years isn't too bad. Hoping the new one will a) play nicely with the Macs/iThings and b) last as long as the old one (if it does it may well be the last one I buy  ::-) ).

OK, it was last week, but while it's updating itself with 65 updates, I can sit here at the Desktop and do other things - I've bought a Netbook - ASUS EeePC Seashell 1015BX. Best deal was from local Currys. PC World didn't stock! £199. Wanted it now for imminent ski holiday.

Need a small portable PC for viewing vids from the bullet cam, my stills cam and for doing stuff on my new eTrex30 (once I've sorted out how to do gpx-y things on that). Netbook will be less hassle as hand luggage and at airport security than the laptop.

Only one snag with it - Win7Starter - I feel a Linux project due to start after the ski trip... :o

But it copes with the lappy's USB mouse (I despise touchpad control), external speakers and saw my network straight out of the box, so has now got its copy of my mp3 library.

Nexus 7 (Google, not Shimano).  The 3G version - though I expect it'll spend most of it's time on WiFi, I wanted to have the option of connecting from a tent without having to deplete the batteries on two devices just to do a bit of IRC.

It seems to occupy a particularly sweet spot in terms of price to functionality.  Key functions for me being a screen big enough to type on at a respectable speed (your fingers may vary), and a battery that lasts long enough that you're not actually afraid to use it.  The Bluetooth HID stuff works properly in Android 4.x, so Bluetooth keyboards (I've tested two that were problematic with Gingerbread) are finally a viable option.

Key annoyances are of course the lack of an SD card slot (though with 32gig of storage, USB host mode is an acceptable compromise - I'm wanting it more as a portable internet terminal than a media player anyway); that it appears on USB as an MTP or PTP device (no Mass Storage emulation  ???); and the rather pointless absence of GSM phone functionality (while SMS is trivial to add, nobody's cracked telephony yet, though it does appear to be a purely software limitation).

The screen's lovely (including the touchy aspects), though not quite up to Apple retina standards.  But that's okay, because neither are my retinas.  The front-facing camera's predictably crap.  Sound's adequate (not tried the headphone port yet).  Plenty of computational grunt, and everything seems reasonably stable.  I really like the form factor: it's only going to fit in the baggiest of pockets (NB: no vibrate motor anyway), but it's big enough to see a whole web page properly formatted, and to do accurate touchscreen interaction without the enormity of something iPad-sized.

I seriously reckon it would benefit from a couple of hardware buttons on the front panel, if only to wake it from sleep, but I expect that's a habit from my phone as much as anything else, and I'll get used to where the power button is by feel in due course.

Spent the usual entertaining couple of hours messing around with adb getting a proper recovery installed and rooting earlier - no real surprises there if you've done it before, though do make sure you pick a recovery designed for the 3G version of the device (to avoid ROM compatibility issues later).  I'm not bothering with an alternative firmware at this point: the stock ROM is stable and *delightfully* cruft-free, and the usually excellent CyanogenMod is a bit young and has yet to add anything of significance.

I've bought a new PC today which should hopefully arrive mid-week. And a nice "professional" monitor too. Should get back to enjoying the photo editing! I'm afraid I didn't feel any compulsion to buy a Mac.

This also means there could be a rather sturdy Asus laptop for sale soon, unless I find another use for it. I feel it's a bit good to throw into a rucksack everyday and possibly a bit too heavy.

It's in excellent condition.

It's a nice keyboard a lot better and less cramped than the ones built into iPAD cases. I didnt want a case one anyway as it makes the iPAD too bulky for handheld use which is what I want it for 90% of the time and I have a laptop as well for writing most stuff on. This just gives me another option for meetings where I dont need to take a laptop but there will be a lot of note taking or for trips where I don't really need a laptop but might have to write things up whilst away, just chuck the keyboard in my bag as well as the iPAD.

Yeah - I liked the look of one of those Logitek keyboards when seen in a Certain Large Computing Superstore. Instead though I bought a Logitek mouse which is unworking. It was a "non-pristine" item (fact I failed to notice) so had been returned to the store by a previous punter. In spite of re-batterying, it remains US. So Cr*p to that.

I also bought replacement innards for a PC case which has been lying around the house for a bit.  It has a 2.9GHz Intel CPU, ASRock B75 mobo, 8 Gb of Kingston DIMMs, new PSU, optical drive etc and that's more or less it. I'm formatting an HDD for it now with the idea that the PC will be a general purpose machine running Linux. Aim is  to relieve the bottleneck created by my missus writing novels on the other ("my") house PC.  Though I can just imagine the kids, like water, will claim it for their own and watch Cbbc endlessly on it.

I've found the various Linux discussions on here invaluable because I is a Linux virgin.  However, so far I've spent almost as much time with failed Linux OSes as I have with borked Windows implementations. I look forward to a working unbloated OS soon

A new desktop PC from Scan.  All of the PCs I've bought for my own private use over the last few years have been economy options.  The last decent PC I bought personally was probably close to twenty years ago, and was a big Gateway 2000 box.  This one has a reasonably good spec, so should last me a while. :)

It's still one of their "Value" range, a G30i, but has 8G of RAM, a 3.2GHz Core i5 3470, a 256GB SSD and 1TB spinning disc.  Much as I'd like to run Linux, pragmatically Windows 7 Professional is going to be more useful for many of the applications I'll need to use, so that's going on it.

I've got spare keyboards and mice lying around, as well as a couple of old LCD monitors, so I'm sticking with those and not bothering on buying any new ones.

I got the order in yesterday (a Bank Holiday), and Scan have already got it in the post to me, with it hopefully turning up tomorrow. :thumbsup:

I'd resisted the iPad keyboard, it seemed to be self-defeating, after all I could just take my MacBook if I wanted to type, but on a few recent trips I've relied pretty much on the iPad. I do write a lot though (you may have noted) and though I'm a dab hand with the on-screen keyboard, it's a bit wearing and it takes up a big chunk of on-screen real estate.

Then I found my wonderful Palm portable wireless keyboard earlier. Ha, happy days. Kids these days don't remember PDAs, and the time when you communicated with distant humans by shouting loudly at them, rather than shouting loudly into a phone. OK, when I say wonderful, it didn't work very well owing to the ropy IR connection (I promise never to say bad things about Bluetooth ever again) but the keyboard itself is excellent and it folds up mini. Shame it's IR but it did encourage me to order a foldable bluetooth keyboard. I'm not struck with the bulky folio type keyboards and the other option was the Logitech Ultrathin Keyboard Cover which looked nice, but a bit of a palaver, and I'm quite happy with my current smartcover, so wanted a keyboard that I could just pop in the bag or poket when needed. Bit of an Amazon lucky dip, so it might be shit. There was a review on YouTube but it was in German. Mind you, for a German he sounded pretty pleased. Or he could just have been really angry. I can never tell.

Impressively, along with the keyboard, I found no fewer than three Palm Pilots – the monochrome goodness of a m100, a shiny Tungsten E, and a TX. If I could find a charger, I'd be well on my way down memory lane by now. I have a drawer where technology goes to die. You don't want to know how many portable CD players there are in there, not to mention a small army of Walkmen, and I suspect a minidisc player. I was actually looking for the iPod shuffle. Never did find it.

The shuffle was on the floor outside my office door (thats if it was a gold coloured one)  I also have a drawer of odd things such as iPAQs, which I used to have in my previous job.  Very useful for checking at home, what my work diary was.  Nowadays, with all the advances in technology, I have to guess, or write it on a bit of paper.  Thats progress for you...

I also used to have a couple of Psion 3s, but someone from ths parish now has those.  Lovely keyboards.

I was amused by a non-work colleague who asked how he could use MS office on his iPad.  My other colleague who works for the evil empire of microsoft informed him that they had written it, but never issued it.  I replied that MS office compatible apps were easily obtained for Android devices, at which he took offence and said they were crap. Erm, but it works, and yours doesn't seem to do what you want...  Actually I thought there was an office app for iPads, but he wasn't getting any more help from me after that.  I would have thought he should have bought a little macbook, rather than an iPad?

what have I bought, nowt since the SSD for the netbook, which has made it rather snappier, but I feel an upgrade coming on...
Title: Re: Bought any computing stuff today?
Post by: ian on 06 June, 2013, 11:20:34 am
Nah, my shuffle (well, the wife's) is silver. I'd quite like it for cycling rather than faff with the phone, but owing to it's small nature, it's been elusive for a time now. My wife doesn't actually lose things, but she does some very effective filing.

There's plenty of MS Office compatible apps for the iPad. I don't think MS have finished their own apps, but I have heard it strongly rumoured that they are indeed busily developing them for a 2014 release. Office was designed with a fully powered computer in mind, so scaling them to something useful on a far less powerful tablet is a challenge. Being able to tweak documents and presentations without having to worry about compatibility issues would be good though. They'd probably get my money.

I've  now charged my Palm TX. I'm not sure what I'm going to do with it.

Oooh, shiny. A nice monitor is lovely. I've not-too-long-ago (maybe six months ish) upgraded to a nice 24" widescreen, and it's a world apart from the old 17" 4:3 I used to use. Not having completely knackered colours helps too  :thumbsup:

But this post is actually about my latest purchase, which will hopefully be winging its way to me shortly - a 16gb Google Nexus 7 tablet. I'd avoided the tablet idea for a while because I'm not a huge fan of touchscreens, but I've finally admitted that while I don't want to lug a laptop everywhere sometimes prodding away at an iPhone just isn't good enough.

I stood on the corner of my Netbook earlier, and fubared the screen. :(

It was never that good anyway, it had an upper limit of 2G of RAM (I'd already jumped it beyond it's supplied 1G), and that was painfully insufficient with Windows 7.  Windows 7 Starter was just about tolerable.

I've ordered a newer netbook, an Aspire V5-122P, but had to go with Windows 8, since it was very hard to find a Windows 7 netbook (and I resent paying an unreasonably large amount of money to revert to the previous version, which was what the few suppliers seemed to expect).  I can probably live with Windows 8, although every other Windows box I'm using at the moment is Windows 7.  This device also has 6GB of RAM and a 500GB disc, so should work reasonably well.

Would be interested to hear your thoughts on this once you've had a proper play with it - I'm currently weighing up whether to go for this or the 'Go' model for myself, also for the purpose of going as paperless as possible.

It's £50 more for the Go, but it does then go up to 600dpi which would be handy for a couple of projects I have planned (archiving family photos and converting into photobooks amongst others).

Also, how are you dealing with the scans? Evernote seems to be a choice of many.

300dpi's fine for me, and the One can (kind of) work as a Go with the addition of some AAA batteries, so I didn't see the point in spending the extra fifty quid. Instead I spent the money on an Eye-fi card, which I admit I still haven't sorted out.

Yes, Evernote is my destination as I was already using it for some other stuff. I still need to get the OCR magick working so that the PDFs are searchable within Evernote, I'm not sure whether I need an Evernote Premium subscription or whether the Doxie software is supposed to do it...

I'll keep you posted :-)

They are really good, for the money.

One thing to watch, though, is that occasionally (it has only happened once in 2 years) the whole machine locks up, the only way to fix it is a complete factory reset.  Thankfully the Kobo Library function will easily re-fill the unit.

One other thing that happened was that the Wifi settings became inaccessible.  Again factory reset fixed it.

Think Raspberry Pi but with a properly open1 architecture and better I/O2.

1 - as opposed to 'mostly open except for the most important bit, getting the specs of which requires you to take it roughly from behind from Broadcom'
2 - more GPIO stuff, plus an ethernet chipset which doesn't share bandwidth with the USB ports.

The Mac Mini has been struggling with Lightroom and Photoshop since I acquired a 24MP camera, so today I finally made the decision and purchased a new computer -

27" iMac
3.5GHz Quad core i7
8GB of Apple RAM (to be replaced with 32GB of Crucial RAM, saving £250 on Apple RAM prices)
NVIDIA GeForce GTX 780M 4GB
3TB Fusion Drive.

Should be with me at the end of the week :thumbsup:

I had been contemplating a new Mac Pro but (a) I could buy 2 of these iMacs for the price (b) it would be sensible to wait some time until all the problems/bugs are known and sorted and I'm getting frustrated at Lightroom NOW!

The Mac Mini is for sale in classifieds.

Didn't get it today, but further fettling of it today reminded me- a new to me Mac Pro (a 5,1- the last of the old version, rather than the new one). 3.33 hex core, 32GB RAM, 240GB SSD plus 3TB & 1TB hard drives. Goes like stink, and compared to the new hex core, only about 20-25% slower on most tasks for about a grand less (even before allowing for the HDs). Video card upgrade will close the gap still further. I was tempted (very) by the new one, but it's not that much better. Granddad (2.66 quad 1,1) will be staying on as backup.

I got an HP Proliant MicroServer towards the end of last year, since the older ones have dropped in price, with a newer one having just been launched.

Together with a couple of 3TB SATA discs (configured in a mirror) that'll keep my home storage needs covered for the immediate future, so long as I don't try to store too many ISOs on there.

It has four drive bays, so I can fit another pair of discs in there eventually, but for the time being I'm just going to use one bay for a 250GB disc and put the OS on that.  I may revert to using the internal USB socket for a flash drive based OS eventually (I've been experimenting with FreeNAS on a 32GB one).

It's a nice bit of kit, even if a little noisier than the QNAP which it's replacing.

Just taken delivery of a second 24" 1920x1080 display, so my main PC is now dual-headed with lots more screen space.
Mostly on account of the new job I'm doing, which is screen-space hungry.

It's an iiyama something or other, and it's much brighter and crisper than the old iiyama 24" it's sat beside.   Not sure if I can put up with the faded yellow whites on the old monitor.

I suppose that's a 1st world problem.

Board #1:  Had things hand-written on a couple of the chips with marker pen; CPU socket contacts were damaged.  I didn't even bother trying it.

Board #2:  Looked in good condition so I tried it.  Lived for a few seconds, then failed to do anything at all.  Removing and replacing the coin cell didn't 't fix it.  Maybe a BIOS chip problem?  I dunno.

Board #3:  Looked ok apart from excess thermal paste all over the place.  Works fine!  Now my PCIe SSD runs at full speed, even after resuming from standby, and I can have full-speed USB 3 and full-speed SATA 3 simultaneously. :thumbsup:

Illustrated computer not included!

It's expensive considering it's mostly air, but nicely designed.  Takes 140 mm fans without being too wide altogether to fit in a fairly narrow space.

Also bought a Corsair Force Series 3 SSD.  Disappointingly, it's down to several times slower than claimed once real data is on it (as opposed to benchmarking when empty), unlike the OCZ SSDs I've been accustomed to.  The access speed is still fantastic compared to HDD, though, of course.

That's a ver' ver' nice case, although I tend to steer clear of the window panels these days, opting instead for (probably snake oil) soundproofing foam.

I've had an Akasa Eclipse for years now (one of these (http://www.akasa.com.tw/img/product/common/feature/00/AK-BKCSE-01V3_f00.png) but without the window) . Solidly built, roomy inside and pretty quiet, although at some point I'll put some money into getting it "properly" silent.

Me too!  I've stuck soundproofing foam over the inside of the window!  :)   (I couldn't find another case with the dimensions and features I wanted without a window).  Actually, the foam will interfere with aerodynamics and cooling, but that's a compromise I'm happy to make.

I do think it's childish to "show off your work", as Corsair say the idea is.  It's also annoying that all my Corsair PSU cables are entirely black, making it harder for me to customise them.  Good PSU, by the way: RM750.  The fan only comes on at 40% PSU load.  Happened to get a load of Corsair stuff because that's what my favourite retailer, Scan, seems to major in.

I had a dsl-320b on order at Dabs.  They were clearly on some ship because quite a few resellers had no stock so I was content to wait. I logged daily into dabs looked at the sales page. On Tuesday morning I was pleased to see that the message changed from long delay to more than 50 in stock.  Then in the evening I noticed that my waiting order was still 'processing'. So on Wednesday morning I canceled the order, I could continue to use the old router as an ethernet modem.  Then I though of the reason I wanted the new modem in the first place. I found some at Morecomputers selected the 3-5 day free postage and it turned up today (next day). Dabs 0 - 1 More Computers.

Title: Re: Bought any computing stuff today?

I've been busy!

The NAS/Server parts acquired so far:

- mATX case
- CPU (Xeon E1220L v2 - only 17W TDP)
- ASUS P8B-X mobo - an actual bargain from eBay, fingers crossed it works
- 16GB low power ECC ram*
- 350w PSU (near silent/bronze rated)

That just leaves me to buy disks and a passive CPU cooler.
I'll probably swap out the stock case case fans for quieter alternatives.

This is all well overdue - my current NAS box is choc-full.

*I'm planning to use either XFS or BTFS which are memory hungry.

Update on my Corsair Obsidian 450D case, with some complaints.......

(http://www.corsair.com/en-gb/~/media/DCB593F1D6E9438993AE39CB1C696284.ashx?w=380)

I've given up trying to silence the case.  It's just much too open with its numerous great big fan holes.  To reduce noise with this, you need to reduce the amount of noise made in the first place, via quiet fans or fanless devices, and SSDs.  It's water-cooling ready (and I'd need water cooling for any more overclocking of my CPU), but I'm not convinced that the water pump would be as quiet or pleasant-sounding as I want, even with a variable-speed model.  My current CPU air cooling is practically silent at low load, and I run the machine at low load for 99% of the time.

You need a cable adapter (not supplied) to use the front panel USB 3 ports with USB 2 if you have a USB 2 header but no USB 3 headers on your motherboard or cards.  Get an adapter (or PCIe USB 3 card) off eBay, and also a motherboard beeper if you want one, as there's no beeper in the case.

The reset button is ridiculously small and recessed, but you probably won't need it often (unlike me at one point, so I made a remote control - which was ridiculous).

It can't take more than two CD/DVD/BD drives.

The two SSD caddies in the back of the case (behind the motherboard) are neat, but it's shame they're made of plastic rather than aluminium.  SSDs can run warm and there's little airflow there.  I suppose they don't get hot enough for it to be a big deal, but still it would seem good practice to sink some heat.  Alternatively, you can put SSDs in the air-cooled HDD cage (that takes up to three drives).

The quick-release front fan filter panel accidentally pops off too easily while handling the case.

Overall, though, it's a nice case, and exceptionally versatile for the size when it comes to fan options.  Still recommended.

See the YACF Classifieds if you'd like to buy the Corsair fans that came with mine.  (I'm using only-slightly quieter Noctua fans instead).

Got a BlackGold triple Freeview HD tuner the day after ordering direct from BlackGold, despite the website implying a 7 day wait.  No, I'm not sponsored by this company, although I reckon I deserve a few quid by now!  :)

They still seem to be having problems with the quad version, which remains unavailable.  I suspect the triple shares the same hardware with one tuner disabled or not working.  Some buyers of the quad complained that only three tuners worked.

A TP-Link W9980 VDSL (does ADSL too of course) modem/router, thus ending several years of putting up with feeble ISP-supplied Technicolor TG585s and freeing up a socket on the power strip. Impressed so far, and great value (£70 delivered)- four Gigabit Ethernet ports, wireless performance pretty good (a massive improvement on the 585, not surprisingly), easy to configure, and speedtests showing results much the same as the Openreach box which it's replaced as well. Recommended if you don't want to spend the extra on the equivalent Billion model.

Post by: Afasoas on 19 February, 2015, 11:23:36 pm
Happy to report that the Energenie sockets and the Pimote play nicely. Took me a couple of hours but that included finding the Pi + gubbins, trying to remember my user name/password, giving up and re-imaging the latest Raspbian onto an SD card and setting it up from scratch. The Energenie bits themselves were working in minutes and I can now switch the big managed switch on and off from anywhere via the VPN.

Now I need to work out how to get the Dell Poweredge 2950 to respond to a wake-on LAN packet. It's not a BIOS option and possibly involves booting from a CD with the appropriate utility installed on it. Must take care to only enable it on one of it's NICs and ensure it's the right NIC as they are both in two different networks.

The WOL is part of the Broadcom NICs firmware not the motherboards. When you boot the server it may display a post message about the NIC in which case hit "Ctrl S" at that point to get into the firmware for the NIC or if post messages have been suppressed hit "Ctrl S" lots of times as it boots and hope to do it at the correct point. The WOL is OS independent
You could get more control than WOL by using IPMI though..

Thanks Pat.
Actually I already tried that. There's no CTRL+S option presented whilst the box is booting, but I hit it several times regardless and no banana.
Using IPMI - does that mean fitting a DRAC card? I read a bit about the on-board BMC but I haven't quite figured out how to enable IPMI over LAN - I've hit CTRL+E in the BIOS and configured BMC IP address/netmask/gateway and I can now ping that IP address. I did a port scan on it and found all the ports scanned were filtered.

Obviously I'm new at this! I might just simplify things and buy a DRAC for it. It seems fairly trivial at work.

Always carried around huge Dell Precision workstation laptops, but more and more I do most of my commissioning work from home rather than having to be onsite (a little Intel NUC sat on site during commissioning phase with RDP).  I have a excellent workstation desktop - so it seemed daft to have to carry a heavy laptop (and I cycle everywhere, so a 3kg laptop/psu is not a good thing!).  I'd rather be sat at home with two massive monitors, a warm, comfy chair and a decent stereo. 

It's a bit of a risk - but I think it'll work out.  I've never had such a cheap laptop!

We tend to order the Saphire Radeon HD6450's for work desktops cos they have dual DVI and HDMI (IIRC)

Why have a VGA connector at all?  You can dongle the analogue signal out of a DVI port just fine, and they all seem to come with that dongle.  Two VGA monitors is expected, but not two DVI?

I suppose HDMI is effectively DVI-D thobut... It hadn't made it to sensible graphics cards last time I was in the market for one.

I don't think there'd be enough room for dual DVI even without the VGA, while supporting low profile, that is, but a second HDMI in place of the VGA would be better for the modern user.  I suppose they want to save old farts the bother of adapting to VGA.

The big graphics cards we order for our developers have dual display port on them, and then you chuck the dongle of choice in the display port or just hook them up to display port capable monitors.

it is funny watching folks trying to plug a hdmi lead into them though, they are almost similar, but slightly not.

That sounds like a good solution.  Presumably they fail on one of 'cheap' 'fanless' or 'decent Linux driver available'.

I've just realised that the Asus graphics card could easily provide two DVI sockets if it had a double bracket (the chunky heatsink makes it occupy two slots anyway), but that'd be more expensive.  It supports dual (and triple) display anyway, and one DVI + one HDMI happens to be what I need.

There are even cheaper versions with the same Nvidia chip from Gainward and Palit, just with less fancy heatsinks (that I bet work nearly as well).

Always carried around huge Dell Precision workstation laptops, but more and more I do most of my commissioning work from home rather than having to be onsite (a little Intel NUC sat on site during commissioning phase with RDP).  I have a excellent workstation desktop - so it seemed daft to have to carry a heavy laptop (and I cycle everywhere, so a 3kg laptop/psu is not a good thing!).  I'd rather be sat at home with two massive monitors, a warm, comfy chair and a decent stereo. 

It's a bit of a risk - but I think it'll work out.  I've never had such a cheap laptop! 

Should arrive early next week - it left China last weekend.

Excited.

Let me know how you get on with it. I am in the market for a new laptop and that (or the even rarer 15" variant) are at the top of my very short list.

I'll find out for you, Dell fit them for us.

In a bizarre roundabout way Dell and HP sell hardware accredited for our software, which we buy for our development teams.

Occasionally the department of insane personal computing at HP will send a tiny form factor 14 core workstation with terrabytes of ram for free to see how it gets on with our software, usually as they send only one they ended up in systems as our personal workstations, I miss being in systems now I'm in the website team.

Hopefully have it soon though.

There will apparently be a 15 inch with Infinity screen later in the year - I could have waited, but I am not that patient.

It'll be an interesting experiment for me - I've not had a little screen for a long time (since the days of all laptop screens being little!), but as I said, I do less and less coding and commissioning on-site these days - and with an Asus MB168+ this laptop still weighs less than my old Precision if I do want some more real estate for site work.

Wi-fi USB dongle for an ancient Pakard Bell laptop with no wireless built in.  I thought about seeing if it could take an internal wi-fi card instead, but I don't suppose it has an antenna for it anyway, like I think modern laptops have in the screen, or besides the screen.

Since my desktop PC has a Pentium 4, half a gig of RAM, an 80 GB disk and XP Crap Edition, and is thus a mere abacus compared with the Asus X102BA netbook, I do not think it is worth resurrecting.

It's about the size of a 4-port Ethernet switch, but with little fold-up antennas on it, has ye olde USB square connectors as found on printers, and a jack for an external power brick.

I've just pressed my old Belkin USB hub back into service.  It can act as an unpowered 4-port job or, by plugging this bit into a base station, a powered 7-port one.  The base station has a handy tray in which to store paper clips, while the power wossname is the size of a Range Rover.  In 4-port mode it sits snugly against the case of the Asus.

Which is nice.

Asus GeForce GT 730 (http://www.asus.com/uk/Graphics_Cards/GT730SL2GD3BRK/specifications/) - one of the most powerful fanless graphics cards.  Only fifty quid from Amazon.

I'll have to get into a bit of gaming to justify the 2 GB RAM and 384 cores!  Wonder what's suitable for middle-aged hand-to-eye coordination?

Incidentally, the Asus GT 730 is only a PCIe x8 job (which happens to be the number of lanes available for the GPU in my system anyway, thanks to a PCIe SSD nicking bandwidth).  You might prefer a x16 card if pushing limits.

That screen cap looks detailed.

Just picked up a cheap 6" Windows tablet and first impressions are surprisingly good. The build quality is okay. It's a nice size to hold and the display/touch sensitivity seem more than adequate. It does seem to be full blown Windows, which is both good and bad. Good in that any Windows apps will run on it. Bad in that it's only really metro apps that are designed for the touch interface.

It's almost completely devoid of any skunkware. And I was able to get it set up without using a Microsoft account.

It's a pity that of the 32 GB of storage, only 20 GB is available to use. That said, I can add a Micro SD card.
It's a nice notion having a such portable/fully fledged PC available to use.

Finally got around to buying a media server - primarily for music playback, although it will rip DVDs & presumably link up with fancy TVs if that's your thing.

It's a  DBM Vortexbox  (http://dbmservers.tictail.com/product/3tb-dbm-premium-dvd-vortexbox-server) & is connected to the network via Powerline/Ethernet & via an  Epiphany Acoustics USB DAC  (http://epiphany-acoustics.co.uk/products-page/dacs/ehp-o2di-desktop-headphone-amplifierdac-3/) to my Cyrus 7 amp.

Control is via laptop or tablet using Logitech Media Sever app or the  Orange Squeeze app  (http://www.orangebikelabs.com/products/orangesqueeze/).

Sound quality playing FLAC files is fantastic - probably better than playing the cd through my Cyrus 7 cd player (possibly due to the DAC being more up to date than the one in the Cyrus).

The only downside is it's highlighted a few tagging issues, mainly with compilation albums, but I can live with that.

I'm having lots of fun listening to old stuff on random play & utilising my hifi again after months of mainly listening via tiny speakers plugged into the laptop  :thumbsup:

Great service from the seller too.

May I recommend an A3 piece of wood?  I use the drawing board (a bit bigger than A3 obv. ) that I used to use for my 'O' level Tech. Drawing homework.  Nothing special; just a bit of plywood.  Light, big enough for laptop and flounder (logitech marble mouse) or trackball of your choice and at 5mm thick no flex.

I like the idea of some heat conduction as well, though, hence my choice of aluminium.  I don't actually use it on my lap.  I place it on my pocketed-sprung upstairs office work unit, where I operate it from a recumbent position.  I was using a piece of cardboard, previously, which allowed ventilation, but was too good a heat insulator.

Yeah, been using that for a few weeks to gradually tidy everything up - just hit the compilation albums, which can be a pain to get into my preferred format. Still on the learning curve though & get a few odd results (eg 'empty' albums listed under, say, artist Robin Saville but correctly listed under Saville, Robin) that all redoing/rescanning don't seem to clear. Also the occasional album that takes 25 min to update!

It's worth getting into MP3Tag's more advanced features to do batch jobs, if you haven't yet, if any batch jobs would help.  eg. if your compilation albums currently have artist names in the filenames (which you can grab to put in the tags).
Title: Re: Bought any computing stuff today?
Post by: fuaran on 29 March, 2015, 09:18:57 pm
For compilations, worth using the "album artist" tag, as well as the "artist" tag. ie you can set album artist to "Various", then use the specific artist tag for each song.
Then you can set your player to group albums by album artist, so it should put all of the compilations together.
The filenames don't really matter. Though it does look neater if they all use a similar style.

On eBay, I bought a new cheap small PC for the kitchen, where I've got fed up using the underpowered netbook.  It's not the most powerful PC in the world, but a Core i3-4160, with 8GB of RAM, and a 120GB SSD should be adequate for most of the functions that I require of it.

(http://balius.sp.ph.ic.ac.uk/~timo/stuff/small.php?size=400&file=MiniPC.jpg) (http://balius.sp.ph.ic.ac.uk/~timo/stuff/MiniPC.jpg)

I'm still undecided on whether to mount the TV on the wall using some species of VESA mounting, or just live with it's "foot" on the countertop.  Using the Bluray player to watch films would probably work better with the TV higher up, but using it as a PC, I'd probably suffer excessively from neck ache, if I was repeatedly looking up at it (plus, there isn't much room for wall mounting, anyway).

It'll probably be quicker to carry on doing them individually than get my head around batch processing! Only some filenames have artist names & I'm also finding a lot of albums where the tag source has debatable quality or is just not available...

I think I'm reaping what I sowed by deleting artist names when I originally ripped the comp cds, in favour of just using 'Various Artists' as album artist  :facepalm:

It's arrived now, and I'm quite impressed by it.  The performance is perfectly adequate for playing media, and browsing the web, it's much more responsive than the netbook that I was using for similar purposes.

Very neat.  Is it fanless?

No, but it's fairly quiet.  With no other sounds, and sat right next to it, I can hear the fan, but if I'm playing music or some video, the sound from that easily masks any noise.  I'd imagine if it was near (or behind) a TV, and you were sat across the room from it, you'd hear very little.

I wasn't really looking for the ultimately quiet machine, I was concerned more about reasonable performance, and this motherboard with the Core i3-4160 does that better than a laptop at twice the price could.  With Microsoft's Windows Performance Index, it actually outperforms my Core i5 Desktop, mainly because the onboard video of this machine is better than the onboard video of that one.  A fanless machine would likely have lower performance, since they tend to trade speed/heat against noise.

Yes, I fear with 95W, you'd need a fairly large radiator to dissipate the heat.  Size was also a criterion for me, albeit not the primary one.  I'd imagine that a decent heat dissipation system would also add to the cost.

An i3 3240 for my ASUS P8Z68-V LX, replacing the existing G620.  According to the benchmarks, it should almost double the performance of the G620, and amazingly, put it within touching distance of my elderly and expensive i7 920.

Interesting, so the i& I just bought for Mrs T has a similar score to the Dell E6330 with Core i5 that I have been using for a while! But way below (less than half) of the score of my current laptop, which is a 4G i7.

I wandered into town this morning to look at getting a new phone - probably Android, I'd thought - to replace my iPhone 5.

Instead, I seem to have come home with a 4G-enabled iPad Air. Oops!

In my defence, it was a good deal and matches my usage well. I hardly ever make voice calls, but like having access to more texts and data than I'm likely to need. So rather than shell out £lots per month for a fancy handset, I've dropped my existing phone onto a cheap sim-only tariff with just a little bit of minutes and texts, and used the difference to get 15 gigs/month of data on a shiny new iPad.

A Netgear GS105 network switch plus a couple of bits of Anbaric String.  Now the lapdancer is more like a Real Babbage-Engine than ever as it is surrounded by String: on the left external HDD, mains voles & HDMI, on the right network, keyboard, external CD/DVD & trackball.  And it talks a fair bit faster to the NAS an' all.

Edit: the switch is going to have to move somewhere out of sight though coz the blinkenlights will make me homicidal once night has fallen.  Also, what kind of cabbage puts the ports on the front of a thing like that ???

Title: Re: Bought any computing stuff today?
Post by: Kim on 07 April, 2015, 09:26:19 pm
I've wondered about that sort of thing myself.

The usual data on the front / power on the back arrangement makes sense for things that are likely to be rackmounted.

With small 'desktop' switches, you certainly want all the cables on one side, and the blinkenlights either on the same, or the opposite side depending on how you're planning to install it.  Domestic kit would benefit from  a more advanced blinkenlight management solution than blutac.  Obviously an LDR or push-to-illuminate-blinkenlights-for-half-an-hour button would add cost, but is the sort of feature that customers who don't understand router specs could find appealing.

Favourite bugbear:  Single channel PoE injectors and the like, with one data socket on each end and the power cable coming out the side.  Makes perfect semantic sense, and looks pretty enough if your anbaric gubbins installation consists of ....a single PoE injector.   :facepalm:

In another step on the road to becoming a fully-fledged Fruit Addict, this afternoon I cycled the mile and a half over to John Lewis and returned with an Apple TV (http://www.apple.com/uk/appletv/). A bit spendy, compared to a Chromecast, but it seems to play very nicely - especially with my existing iStuff. Like all iThings the main joy is the UI, which is much more enjoyable to use than my previous attempts with Raspberry Pi, MiniATX boxes and teeny little wireless keyboards.

At this point I'm becoming increasingly sure that true to Cupertino's plans my next PC will be running OSX (no way am I going to Windows 8  :sick:). Most likely an iMac, or perhaps a Mini if my monitor is still going strong when I upgrade.

The only problem is that pushing my music library through the TV has only highlighted how poor the inbuilt speakers are. Sadly my decrepit stereo amp isn't up to the job (no optical in, no remote) so an expensive trip to Richer Sounds for an AV receiver might be on the cards one day...

Big computery purchase today!

I've just got home with a 2010 21.5" iMac, bought from someone I know on Twitter who has recently replaced it with a very shiny-looking new model. I've been hankering after something OSX-y for a while, and this was too good a price to pass up.

It's rather pretty, and with the dinky little keyboard and mouse my desk feels very sparse which is nice. It's currently downloading Yosemite, after which the fun and games of moving everything over from my PC, installing software, finding alternatives for my Windows apps, and everything else...  :thumbsup:

Not bought today, but delivered.

Hopefully should be more reliable than my Jawbone Up, that lasted 10 weeks before breaking.

The fact the Vivofit doesn't need a cludgy way of syncing with your phone means they are already streets ahead of the UP.

A mechanical keyboard.

I have moved desks at work and the new keyboard I was given probably cost less than 50p and was spongier than Spongebob Squarepants.

It probably cost as much as some people spend on a cheap laptop, but typing is what I do all day and it will probably last until retirement. It is an absolute joy to type on.

They decided I could use a fondleslab, but knew better than get me an Apple product.

So I've managed to get it working as I want, with webby stuff and connecting to my IMAP mail.
I've used Handbrake to re-encode some LOTR blu-rays to MP4 and those seem to work well.
The screen is totally lovely.

And over the weekend, a new lapdog for Junior to take to Uni.

It's a Lenovo thing, quite powerful.
But the screen resolution is senselessly high 4k ( 3840x2160 ) for a 15" display, which means each pixel is about the size of an atom.
This means all the windows things have to have their magnification set to 250% by default, which in itself causes some windows to become fuzzy!
Some windows seem to be aware of scaling, and render themselves much more pretty on the hi-res screen, but many don't, and the dumb magnification is ugly.
Some programs are unaware of the silly resolution, and remain un-magnified, and continue to have icons 16 x 16 atoms big.

They are sensitive to noise on the mains, so if they are dropping out at a particular time of day, what electrical appliances are on then that aren't on at other times?

The angel of temptation has whispered sylphy promises in my ear, so after a couple of days playing with a brand new 5K iMac, I'm wavering on the entire preserve my early-2009 Mac Mini front. Computers don't run on coal now days, I'm told.

But seriously, what's the fucking difference between a m280 and a m290 graphics card other than a number and an amount of cash? Do I need that extra ten? I'll probably follow my usual mentally anaemic logic and buy the middle one. Oh wait, I can choose a M395 for – wait, how much? – that's an extra five. FIVE.

Five not enough for you? Let's notch it up. It's time for the big guns. When numbers aren't enough, you know it's time for...

3-9-5-X.

An X is always cool. It'd be better if it was XXX. That was certainly the case during my teenage years. But not XXXX, which is Castlemaine, probably one of the fouler substances on the planet. Not wait, the foulest. There's probably a good reason why I don't work in marketing, but I know when one X is too much.

I probably shouldn't make expensive purchasing decisions with a beer in hand.

Stupid question, because I used to know this stuff, but times have a passed since I last built a PC - I'm buying a swanky new iMac and avoiding the Apple RAM premium (£160, I don't think so dears).

Usually memory slots come in pairs, and you ideally want to put matched sticks of RAM in the paired slots, as this allows for higher throughput.

Random motherboard fussiness about order and sizes is usually documented in the manual, but my Mac experience pre-dates this sort of thing.

On a lot of the new Macs the memory is soldered directly onto the board, yes the RAM as well. I'm 100% the macbook, macbook air, and macbook pro are this way and I wouldn't be surprised if the imac isn't the same.

D>

Nope, there's still a panel on the iMac that let's the user shovel more RAM in. To be honest, I'm unsure that I need more than 8GB. My Macbook Air is soldered, but after a day of hammering away with 4GB, it's swapped about 60MB (and that's with Mail, Keynote, Word, and 12 Chrome tabs open) – currently hovering at 3.5GB used. My current Mac Mini has 8GB and whenever I've looked it's never maxed out. They're both pure-SSD machines, as will be the new iMac.

I'm just being greedy. That said, I'm planning a bit of video tinkering which the 2009 Mac Mini isn't really up to (and part of the reason I'm finally upgrading an otherwise perfectly good machine), though I'm not exactly going to dive into the realm of 4K.

After some research it seems that pretty much if you not wrangling huge datasets or virtualising a million machines, you're not going to get much value beyond 8GB, so I might hold at that.

Ironically, I do have to wrangle huge datasets. In Excel. On a Windows laptop that the mothership saw fit to limit to 4GB. Calculating 1%...........2%...............................3%............................

Yeah, I could do it on the Mac, but if you've met Excel 2011 for Mac, you'd understand that no matter what processor or how much memory, it performs like a benzodiazepine-dosed slug.

Ah, well, you see, I used Excel to build The Great Prognosticator. In simple terms (and it's a lot more complicated), I created a formula so iteratively complex that it practically tied a bow-tie in space-time and effectively made the future history and history future. The Great Prognosticator has a prodigious appetite for data though. I shovel in as much as possible and command 'Calculate Prognosticator!' The Great Prognosticator belches like a dragon with indigestion, and then after many hours of fitful snoozing, the curtains are yanked back on the future. Or I have to hit Ctrl-Alt-Del and try again. It's marginally more accurate than necromancy.

Ah, why don't you use a database, you may ask? Because databases get used by minions in Hyderabad who get paid a lot, lot less than me. I could command such a minion to do my bidding, but to be honest, it takes longer to explain than do. And they'll do it wrong. I'm not a natural delegator.

In other news, my splendidly shiny new computer is apparently enjoying the craic in Cork. I'm sorry little Mac Mini. I fear you're soon destined to the dark cupboard under the stairs with the gas and electricity meters and numerous spiders, where you'll have to evict an even older (good god, 2006) Mac Mini that acts as my secondary backup NAS and ripper of DVDs (it takes about four hours to do a movie, but I queue 'em up and let them go).

So my Wet String phone line is now enabled for FTTC!
Woohoo!

As AAISP use the 'wires-only' install method for FTTC ( as opposed to a 'Managed Install', where a BT engineer visits your property and installs a new VDSL faceplate and provides the modem ), I have just purchased a Huawei VDSL modem and a BT OpenRetch VDSL 'interstitial' faceplate for the NTE5.

A call to AAISP on Monday to initiate the re-grade.

<ETA>
Lots of grubbing around on AAISP website to see what the FTTC re-grade will mean in terms of tariffs.
I'm on a legacy tariff, and have a /26 IPv4 allocation.
The re-grade will force me to change to a current tariff, which will probably be home::1.
But that only has 1 IPv4 address.
I really don't want to give up my IPv4 space just yet.
But their FAQs state that "In some cases, existing customers with IPv4 space can move to Home::1 and retain their IPv4 space."
I'm hoping to invoke that clause.
I've had a quick forray on irc, and I got an opinion that the 'some cases' means existing customers with an IPv4 allocation.
I will call them on Monday, and see what I get.

Feanor - I got a upgrade to FTTC on my AAISP connection in January that involved new faceplate and modem supplied and some internal rerouting so the modem could go in my office upstairs for the standard upgrade price. I was on legacy (I assume you mean the unit tariff) tariff with /24 IPv4 allocation. This has all just stayed the same i.e. same address block for both IPv4 and IPv6, same number of units - monthly cost went up by £10. Only difference has been a tendency to burn through my units at a faster rate as Mrs M and I can now stream different films at the same time. I have got the full 40Mb downstream from the start - actually I seem to get 42.5Mb, 7.85 on upstream.

If you need a modem I can let you have a BT badged Huawei HG612 (for collection with a Firebrick 500 of yours that I still have!) as I got a spare when I was messing around with modified modem software.

Another iMac yesterday.
The first one (only about 4 years old) decided yesterday that it wasn't capable of backing up my iPhone 5s (although it did so quite happily until I installed the latest iOS on the phone a couple of weeks ago) as I don't have the latest version of iTunes, and guess what - my old iMac won't run the latest version of iTunes.
I'm running OSX Leopard on that, 10.6.8, and that is never going to move forward, as if I were to do so, 20 years worth of Power PC based work and other stuff would cease to be accessible - unless I updated all of the software which was used to create it...... I don't think so.

I knew this day was coming, an increasing number of pages were failing to open in Safari, as that is a no longer supported version - the workaround was to use an alternative browser.
So now, the two screens sit side be side.
The past 20 years on the left (backed up by time capsule) the future (from which this missive is coming from) on the right.
Trying to figure out what's the best way to transfer files between the two.
The additional ethernet cable the nice man in Peter Jones sold me yesterday for £20.00 is not going to do it, contrary to what he told me - as each machine has only the one ethernet port.
Gah!
Thanks for that - that'll be returned unopened for a refund.

It also meant my Saturday afternoon was spent on an overcrowded tube (Yuk!)
But it had the bonus of a taxi from PJ to Victoria Station where I treated myself to a filthy pastie from The Cornish Pastie Co, before catching my train home with the iMac.

Most impressive was the ease with which I was able to set up my email account using mail for Mac. Quite extraordinarily easy.

Post by: ian on 25 October, 2015, 06:11:55 pm
I think you can do it by connecting the machines directly via cat5. In the old days it was a crossover cable, but I think ports autodetect these days, and you get an ad hoc network. One of those clever network types will undoubtedly be along in moment to tell me to shut up. I'm from a time where we bundled ISDN lines to hit 128kb/s and dinosaurs were having their 'going away' parties. Hoverboards were within our reach, I tell you.

My new iMac has voyaged from Ireland and is now sitting in a UPS depot in Croydon, probably plotting my next entry in the shite couriers thread. I'm planning a clean install to rid myself of a decade of crud. There'll be swearing as bugger knows where the serial numbers have fled to, and I'm pretty sure the Canon scanner software will involve me burying chicken bones at the crossroads and calling up Finestre, the Demon of Such Things, and making another bargain.

Top marks on a the filthy pasty, it's a secret shame of mine too. As my wife says when I slink in after a night out – you stink of pasty. Yeah, well, actually CK's pasty pour homme.

Indeed, Cat5 is what the man in the shop said, and sold me.
Unfortunately, as each machine has only one Cat5 port it means deciding between two iMacs going "yadda yadda" or an internet connection....
Will it work via USB?
Or 'Lighting' ports? What are they for?
Wi Fi?

I presume he sold it as a once-only migration, though you could have done it over wifi via your router. If you're just planning to share files between the machines, use Dropbox or iCloud.

If you fire up Migration Assistant it'll give the options for moving stuff between systems.

What sort of modem/router are you using, and how many ethernet ports does it have? Probably easiest to plug both computers into that.

And £20 for an ethernet cable seems rather expensive. Unless its particularly long etc. Even PC World would sell you one for less than £10. Or Poundland often have them, 1m long for £1.
Title: Re: Bought any computing stuff today?
Post by: Jurek on 25 October, 2015, 06:40:10 pm
Quite possibly he meant it as a once only migration. That would be the norm, I guess.
I am not. (The norm).
I've no intention of doing that as the old machine will be used for running the old stuff, and it'll be only the occasional file or link from the old machine that I'll want to shift to the new one.
I guess it'll be so infrequent I could do it on a USB stick.
Or would it work with a USB lead between the two?
And how would that manifest itself on the screen(s)?

@ Fuaran
BT Hub, not the latest one - it has 4 ethernet ports.
Both machines are currently plugged into that. As well as a windows lappy.
The ethernet cable is 10m - it is all he had - hence the kerching! :(

Yeah, but that's not the sort of Cat5 cable you can take a dinner party where it will, sotto voce, mention how much its house cost before sharing a simply splendid recipe for galette.

But yes, Jurek, if you want to share files between the machine, then provided they're on the same network behind your router (which they should be from your description), then just select the folders on the other machine (in Finder, you'll need to provide any password details). A better solution, that doesn't involve having both machines on, is Dropbox – the shared folders will then simply sync with each other via the internet (or directly if both machines are on).

The network cable which connects the Great Hall of Larrington Towers with the estate office upstairs must be 15 metres long and cost about four or five quid from Ebuyer, while the short one between Great Hall network switches was well under a quid.  No good if you want one NOW obv.

Apple stuff talks networks like other stuff. Any computers on the network should (eventually) show up in the Finder, or you can connect directly by Cmd-K.

Jurek, note that if you want to keep your old computer but reclaim some desk space, you can run it headless (i.e. no monitor or keyboard) and use 'screen sharing'. Just fire it up and connect using the 'share screen' option in the Finder and your old computer desktop will be available in a window on your new computer.

I have an entire drawer filled with a spaghetti of network cables. I think they breed. I have trouble throwing things away. I was most disappointed the other year when I tried to open my c1996 P133 Canon laptop and the now brittle case cracked open. The Windows 95 startup sound is still the best ever (composed by Brian Eno, and ironically, on a Mac).

My new iMac is apparently out for delivery. Dare I pop to the swimming pool? Couriers lie in wait for opportunities like that.

Anyway, I'd recommend you use Dropbox, simply put all the files you might want to share in the Dropbox folder and let the internet take the strain. It'll update to the latest versions on whatever machine you happen to start up.

Wife tells me she has a text to expect delivery in the next hour. Ding goes the doorbell on time! Like a happy dog I go pounding to the front door (because couriers allow 403 ms waiting time before running back down the driveway and leaping into their van and disappearing into the sunset). Expecting a 14 kg box of goodness, instead I get handed a small padded envelope.

Turns out to be a bloody mobile phone adaptor. It's nice they have to-the-minute timing for that, but not the bloody iMac which will, helpfully, be sometime before 'the end of today.'

Anyway, didn't get time to set it up, so it's looking at me from the other side of the desk. Instead I spent entire hours cursing Finestre, the Demon of Such Things, unknotting the Medusa's bad hair day of wires under my desk. Seriously, how many fucking cables and power sockets and adapters do these things need? Two monitor cables, mini-displayport and the other kind of adapters, USB this, USB that, scanner, ethernet cables, lightning and old skool Apple connectors, assorted dangly USB leads of varyingly confused sizes for cameras and other devices. Wireless, my arse. Then there's phones, desk lamps, a hard drive enclosure that died whenever, the world's most cantankerous USB hub (do those things ever work?), bluetoothy speakers. It kept coming out. It was liking mining a seam of slightly outdated technology. Eventually, tabula rasa. Or more aptly, sub tabula rasa.

Now I have to put it all back. It starts tidy, but it goes all dreadlocks in a swimming pool when you stop looking at it.

In the morning, 43% then using the fast charge 1:20 to full.

Interestingly, the new 6 is distinctly average in the battery performance stakes, probably as it has bigger screen/processor. I've no reason to suppose that the 5X will perform any better than its predecessor in heavier use (as battery size is similar), but as someone who uses their phone in fits and starts rather than in constant heavy use mode, >doubling the one day between charges in light use and fast charge was a worthwhile upgrade for me.

A pit of 'lectrical vipers now writhes under my desk. You don't want to know how much cat fuzz I found back there, it's evidently a place where the cleaner fears to go.

I find USB to be most confusing standard there ever was, but I assume that USB3 allows for more juice anyway (900mA per port), so hopefully it'll be beneficent to my older USB2 devices.

Barakta received a partial delivery of her DSA equipment yesterday.  So she now has a book-friendly scanner for which the Sane developers abandoned all hope, but works admirably quickly under Windows, and more freakishly, the latest copy of Dragon.  This is the engine they used for Siri, and has finally reached a point where I consider it fit for purpose.  You barely need to train the thing, other than to sort the audio level out.

The reason why Dragon v13 is *so* much better than 12 is because they had magnitudes more training data from Siri et al to improve it with as they could ID when it had misunderstood. V12 required about 15 mins of training, 13 seems to require less than 5 mins, especially if you are Kim and it picks you up freakishly well.

One that I suspect will edge closer to my desk as the week progresses. I go quickly from Apple Store to Junk Store.

At work, our software product has a module which I'm involved with, which is very CPU-intensive.
So the underlying Matlab code had multi-threading enabled, to use a certain number of CPU cores.

This works fine on standard i7 machines with 4 hyperthreaded CPUs, ie where you get 8 virtual CPUs in the performance graph.
But customers with newer machines with more branez were getting Matlab errors relating to trying to start up worker threads.
Matlab was getting it's knickers in a twist counting cores.
We think we know what the problem is, and have coded a fix.
But we had no machines at work to test this out on!
New PCs with multi-branez are expensive.

So my cow-orker did purchase from eBay an old ProLiant 1-U server with dual quad-core hyper-threading Xeons for the princely sum of £50.
This arrived today, and it's been screaming like a banshee on my desk as I wrangle Windows onto it.
That's the thing about 1-U servers: the fans are stupidly small, stupidly many and stupidly high-RPM.
The rest of the office have been glowering at me.

Ah, new USB hub actual powers thing (went for an Anker 7+3 charging port hub). Good god, it came with yet another kind of USB connector for the Hub end. Only minor disappointment is that the external drive (the independently powered one) doesn't power off when the computer shuts down, presumably because the hub still distributes power. Solved by yanking the cable out. In man vs. computer, lo-fi always wins.

Quick review of recent shiny (because someone asked).

New iMac is lovely. Less so for graphics, you'll need to try to see the difference, but for the text which floats on the screen like high quality print, not a pixel to be seen. For those of us (probably me, myself, and I) who love text and typesetting, it's it a thing of beauty to see text so luminously and perfectly rendered. Everything else now looks chunky and harsh. I have it up and running next to the mothership 1920*1200. The comparison is stark. You take it for granted on smartphones and it's the future for desktops and laptops.

Other stuff, if anyone is considering the shinies. It's fast (go SSD, Apple are taking the piss with spinny drives in 2015). Apps open instantly, even the dreaded Office 2011 in less than a second. Startup from bong to app open is <15 seconds. It does seem to be Spotlight indexing forever, for some reason, but then the machine has only been up and running for a few hours in total. A small measure of forever anyway. Yes, yes, you can get better spec for less, but that's not the point. Design is now old skool iMac but why mess with something that looks that good.

New Magic Keyboard isn't very magic, more Macbook than the slightly clunkier old model, with less key travel. I wouldn't upgrade an existing keyboard. Adaptive backlighting, as per Macbook, would have been nice and seems an obvious omission. Otherwise, it's just a keyboard. If you like a Macbook keyboard you'll like it. Your wallet less so, if bought independently.

New Magic Mouse looks like the old Magic Mouse. Like the keyboard it's now rechargable. I personally never found changing a set of batteries every couple of months that much of a chore, but I guess loose batteries upset someone's office feng shui. Magic Mice are a bit love–hate (I love them, but if you're a mouse grasper you'll hate), and there's nothing different about this one, other than a few grams it's physically identical. They could have gone for the haptic feedback and force touch, not sure why they didn't. The internet is up in hands about the charging port on the underside (presumably because it's the only flat surface) – it takes two minutes to get a day's charge apparently, so I guess there's a lot of very busy who don't have two minutes to spare, presumably because they're complaining on the internet.

Only gripe is my mouse has a bit of a top wiggle that the old one doesn't, so unless my hand is resting on it, there's a pronounced (and noisy) tap before the spring engages. Not sure if that's design or a bit of a flaw in mine, may wander by an Apple store and see if they'll swap it.

Yes, that sounds like it. It's a minor nark, probably a fraction of a millimeter wobble that I might not have noticed, but back-to-back with an the older mouse, the clack it makes – particularly for double-tabs to bring up Mission Control or anything else that doesn't require an actual physical click – keeps annoying me. Of course, lost in the noise of the average Apple store, it'll probably be inaudible and I'll look like I've gone a bit mental and am hearing things.

I got one of the new generation Unifi APs today, it set up and ran just like the old ones except its 2.4 and 5GHz 2x2 for about £80. Smaller, too. I do wish they'd put proper POE on the basic ones but otherwise it's looking good so far.
The pro version of the new generation aren't due till January, they're 3x3 MIMO, dual LAN (not that I use that much) and use proper POE which keeps my cabinets tidier.. but hey.

Good to know.

Will probably invest in the Pro version when they come out, as we've got an abundance of 48V PoE kit (and an aversion to extra dongles and wall-warts), and an increasingly flaky old Netgear thing running DD-WRT as an access point that could do with being retired.

I tend to use second hand HP Procurves for POE, for much cheapness. Although the ones that can do POE over gigabit ports are a bit pricier. I don't know if you've played with the Unifi controller yet but you'll need v4.7 at least to run the new APs. No biggie, just a pretty big download when you're clutching New Shiny :)

It would be mine, but the fileserver has a gert big USB disk that hangs off it, and all the associated cables.

The firewall doesn't have the disk, but does have a rat's nest and is in the hallway, so people have to step over me whilst I am trying to fix issues.  I also need to be in reach of the DSL and switches, which also live in the hallway.

Cool just about covers it (not in the heating sense!)

It works, it is IP enabled, so can turn the heating up as I head home, it is currently learning our home/away patterns and it is a lot more reliable than the old thermostat.

Including the tuits?   ;D


I think mine (now on its third iteration) probably does a better job than the Nest, as it has more data to work with[1].  Obviously it's the antithesis of the Google learning-based approach, being an old-fashioned rules-based system.  But that works well iff you can collect some data and hand-craft the rules to do the right thing.  Being able to log in and give it a kick when you're on your way home is priceless.

It was a long time ago now, but we saw a huge reduction in gas consumption from simply not heating the downstairs when we weren't using it.  Of course, you can reasonably achieve that by carrying a modern wireless thermostat around.


[1] Off the top of my head: Individual room temperature and occupancy.  Whether we're in bed.  If there's a guest sleeping downstairs.  When the alarm clock's set for.  The front door opening.  Whether there's food cooking.  Probably some other stuff I've forgotten.

It has a manual, but its entirely focused on installing it as a replacement OS disk, and witters on about data migration, which of course is nonsense in this instance.

In Windows, probably easiest to use the Disk Management tool (run diskmgmt.msc). That will let you create partitions, and format it as required, and give it a drive letter.

There's an iThing lurking downstairs.  Fortunately it's a present, so I don't have to install iTunes on anything.

Now it's lurking in here. We have to remember to take it with us when we visit the intended recipient. Due to Apple emails I need to give it to recipient then do the sodding config...

I cheated and used the tools in Acronis True Image, which did the biz.  A bit obvious if I'd thought to look earlier, there's a tool called "add new disk"!

Its already got a couple of hundred GB of data on it now...  Next dread is dealing with the 3150 photo and video files I got back from Sierra Leone, with.  Lightroom, here we come!

Make sure you keep them backed up. SSDs failure mode tends to be silently corrupting data.
Title: Re: Bought any computing stuff today?

I will!
There's a general PC backup using Acronis, onto one spinny disc, a manual one of critical items such as photos onto another one, and this particular collection is going to be lodged with the British Library under their endangered archives programme.  There will also be a copy held in York, and one somewhere in darkest Dorset, and eventually one in Sierra Leone.  I hope that should cover it.   Not that I'm being over-cautious or anything.

My personal reason for using SSDs is that I'm extremely impatient!

A second TP-Link powerline WiFi thing arrived today to replace the dying Linksys running Tomato in the attic. Plugged it in in the lounge/kitchen and shut off teh WiFi in that attic and we now have reliable WiFi again and a lot faster too.
I'm quite sad that all my old WRT54G WiFi routers are now retired as they have served me well for a decade.
Still all modernised now with the BT Home Hub 5 in the office handling WiFi duties there and connecting to broadband with two poweline APs in the main house plus a poweline ethernet adapter in Pcolbeck juniors bedroom for gaming
I also ordered a couple of five port gigabit Ethernet TP-Link today so I can replace the WRT54G in the attic completely (I turned its WiFi off but its still acting as a switch to connect a few Ethernet sockets in the house to the office) and tidy up the wiring in the office.

I cant believe you can buy a green (only powers up used ports and takes into account cable length)  wall mountable gigabit switch for £12.50 but according to Mr Amazon you can. Amazing.

I've just retired a couple of trusty old Cisco Aironet 1200 Access Points.
These were running at 802.11g speed ( 54Mbit ).

The new ones are:
http://www.linksys.com/gb/p/P-LAPAC1750/

These do 802.11ac, at silly headline speeds.
My phone is claiming 780Mbps.

You get a lot of bang for your buck these days.
Dual-band concurrently;
Multiple SSIDs per radio;
Full VLAN support ie each SSID can go onto a different VLAN;
Proper WPA2-Enterprise support ( via RADIUS server);
IPv6 support ( for the config pages ).
Cluster management ( One AP acts as the Wireless Access Controller, essentially. )
Title: Re: Bought any computing stuff today?
Post by: Kim on 01 April, 2016, 02:29:12 pm
Similarly, I recently retired an old 802.11g Netgear router running DDWRT that had become flaky (presumably a hardware fault).

Replaced it with a Ubiquiti Unifi UAP AC Pro (https://www.ubnt.com/unifi/unifi-ap-ac-pro/), as the #a&a crowd seem to rate the Unifi stuff highly for its doing what it says on the tin factor (there seem to be a lot of people running point-to-point links with it).  I also wanted 802.3af support (I've got enough 48V passive[1] PoE kit that it seems pointless having an extra wall-wart), and the simultaneous dual-band because this is a student area and the 2.4GHz band is a mess.

Feature list broadly similar to the above.  Notably absent is any form of IPv6 support  (being a Layer 2 device, it'll happily pass IPv6 packets anyway[2]), but that's surely coming in a software update at some point.

The Unifi management is via a centralised server, which will run on all the popular OSes (or you can pay them for some cloudy thing, I think).  Installing it on Debian Jessie was just a matter of adding the repository and installing via apt-get.  This is somewhat overkill for a single access point, admittedly, but it works well enough.  Looks like a neat integrated solution if you've got multiple pieces of Unifi hardware (it allows you to manage switches etc via the same interface).

Wireless performance seems okay.  One strategically positioned AP covers the whole house, so no need for a second one.  We're mostly using it for phones/tablets, so aren't really taxing it at present.


[1] My deaf alerting system actually has proper 802.3af support, as do the Snoms for that matter, but I'm using fanless Procurves and passive multi-port injectors rather than proper PoE switches, because I'm cheap and fans are evil.  You can generally stick 48V up something that speaks 802.3af and it'll just get on with it.
[2] Unless you enable the AP's "guest mode", which seems to break it.  I didn't need that feature anyway.
Title: Re: Bought any computing stuff today?
Post by: Feanor on 01 April, 2016, 02:41:27 pm
The Unifi ones were high on my list, too.
Mostly based on RevK Rants blog, and consequently also on #a&a.

The Linksys also does PoE, but it's a bit power-hungry and needs PoE+, so I have to use external inline injectors as my PoE switch isn't up to the job.

The IPv6 stuff is a bit of a gimmick, because as you say, an AP is primarily a layer 2 device.
So in that respect, *all* APs are IPv6 compatible.

But the web GUI is accessible over IPv6.
Several other features seem to be IPv6 aware.
It doesn't look like it can talk to the RADIUS server over IPv6.

Just like this, it's my home-brew PoE injector from before I had a PoE switch:

Heh.  Is the blue cable the old two-100M-ports-on-one-cable bodge?  I think I've mostly eradicated those.

I've got a proper Cisco PoE injector somewhere.  And possibly a bulletproof 802.11b WEP-era access point to go with it.

Post by: Feanor on 01 April, 2016, 03:36:55 pm
No, no such bodgery!

The 3 patch cables you see all go to the switch.
Of the 3 cables inside the wall, 2 went to WAPs with added hard-patched 48v.
The 3rd access point was never needed, and that cable was re-purposed for the weather station server, and no longer carries the 48v.  That's the blue wire.

My phones all have proper Cisco PoE in-line injectors.
There's a bank of them, they all clip together nice and pretty.
They are fed from a single open-frame 48v PSU, rather than a pile of wall-warts.

Top tip for PoE - get a second hand HP Procurve switch. They last pretty much forever and come up on ebay all the time. You can get a 24 port 10/100 switch (with gigabit uplinks) for £50. All Gigabit ones are more expensive, but they're all excellent.

So, with the RasPi recording Garage Temps, I find the idea of running a fully fledged weather station tempting.

A few mouse clicks later, I learn Maplin sell one for sixty BRITTISH pounds and with the addition of a RFM01 transceiver, the Pi can be made to read the data that the Maplin weather station collects. This expenditure could of course be justified as it will mean my planned smart central heating controller will be able to take account of weather conditions. My theory is detecting a drop in temperature and turning the Central Heating on sooner rather than later could save some energy.

And with all the heavy rain we've had lately, it'd be nice to see some data on a graph!

One of these just arrived: http://www.portablepowersupplies.co.uk/portapow-dual-usb-power-monitor-v3/

I'd pre-ordered it, as for 9 quid including shipping it seemed worth a punt.

Initial impressions are that it does what it says on the tin.  Build quality and accuracy is substantially better than the incredibly useful but cheese-quality USB volt/amp meters you get on eBay for a couple of USD.  That it keeps a non-volatile running total of amp-hours is a major bonus.

My only complaints are that a single button UI makes for a lot of clicking (but keeps costs down, so fair enough), that the display is almost unreadable without the backlight, and that the current accumulated registers are numbered 1-9 rather than 0-9 or even 1-0 (surely everyone who has use for such a device can cope with 0 as an index).

BT Infinity ordered. BT TV ordered (currently using an old Sky box as a freeview box). Just need to speak to upstairs and downstairs neighbours to see if they need their aerial sorted (ours isn't working) when I get someone in to do that.

Gigabit powerline adapters ordered (I have some computers that don't do wifi in another room).

Gigabit switch and new Cat-6 patch cables ordered. I know my old random cat5 cables will probably work, but I've been hoarding random cables for years so it's finally time I got rid of the old lot and started again.

A few bits an pieces sorted out.

TalkTalk finally fixed the aDSL line.
So I complained bitterly, obtained some refundage and then switched out to Post Office broadband - it looks like the best value contract and given that it's for failover, should be sufficient. I honestly don't think it will be any better than TalkTalk should things go pear-shaped, but I can quite justify the spendiness of AAISP etc.

Ordered a bridgeable aDSL modem as I don't need the extra trickery/power consumption of a "super-duper-voodoo-hub". And whilst I was there, ordered some 4 gang extension leads with IEC 14 connectors so that I can run the modem/switch (along with the servers) off the UPS backup outlets and the nuc/brix/pi from UPS surge protected outlets.

Some ASUS iKVM modules for both servers so that I can has out-of-band management also made the list. Mainly because the server boards were EOL ~2 years ago and the modules are getting rarer/more expensive. With the firewall virtualised on one of the servers, I'd still be limited on what I can do away from home unless I switch to a highly available pfSense arrangement.

So that leaves me contemplating some more spendy stuff, which will inevitably have to wait a while. The main server has an 'idle' power consumption of 21W* with the quad port NIC - I'd have to change the PSU, boot disk, CPU, fans in the backup server as well as adding RAM/quad port NIC to get it's power consumption down to something reasonable, whilst making it suitable for running another virtualised firewall. I'd also have to obtain a new switch as I'd need 6 ports just for the firewall->WAN connections. Maybe it's overkill, but the server's gone down unexpectedly twice the last two years and that represents a major inconvenience when I'm on-call.

*Could be less with a modern NIC

The server contains 12, yes twelve, fans and consequently is slightly quieter than a 737 engine spooling up vacuum cleaner. I tried disconnecting one of the pairs of fans, but the BIOS just drove the remaining fans faster. There is nowhere in the house it can't be heard.

Been waiting ten days but finally someone in the UK has got some examples of the latest Nvidia GPU graphics cards in stock, which should make the 4k monitor sing and dance.

Which one's that, Mr L?

I'm about to "go 4K", and allegedly my onboard graphics does 4K, but I'm suspicious it might do better with a real graphics card.  However, I have a pathological hatred of noisy PC's, and wanted a silent fanless card.  My early investigations (considering I lost touch with graphics card developments about 10 years or more, ago) suggest that getting anything that will drive 4K and has a displayport output is quite big, noisy and expensive.  I'm not into gaming, but I do want good video, and obviously a quality output for photo editing.  I may also decide I want a dual monitor setup, with the existing 1080p monitor as the other one.  That uses a DVI-D input, but I can't recall if it also has displayport (I don't think so, but I'll check later).

Any polite suggestions as to "not too extreme" graphics cards that tick my particular boxes?

Mine is an MSI GEFORCE 1080 Gaming X which, far from being fanless, has a pair of them.  They'e a lot quieter than the Nvidia no-name job that was in the machine to start with but combine that with the two fans in the PC and it's not silent by any means.  The music and lorry noises drown them out though :)

My rule of thumb is that if you want a quiet server, you've got to mantle it from parts that don't have 'server' written on them and sacrifice the space efficiency.

(Current home server is in a 4U case designed for disk arrays:  High-end desktop motherboard that doesn't have rigid ideas about fans.  About a dozen empty hot-swap 3.5" drive bays on the front (and a few with disks), 4 slow-revving 80mm fans in the middle controlled by a gamer d00d 5.25" bay fan controller, and low-end CPU and high-efficiency ATX PSU with 120mm fans on tickover.  Main compromise is lack of filtration on the dust intakes, but you wouldn't get that on server hardware either.)

Nor me, but all of my hours of looking at specs of graphics cards has resulted in absolutely no silent ones, and anything that has 4k and displayport connection seems to be well into loony gamer territory.  They then proudly announce they can run 4 4K displays.  Christ, its a struggle to pay for one of the damn things, I'm not spending £2k on monitors!  Yes, I know you can get cheaper 4K monitors than that, but I want an IPS panel, and decent colour accuracy. 

My silent PC has 3 case fans (120mm) which only spin up when it starts, and then amble along totally silently, as well as the power supply fan (also huge and slow) and the processor fan.  The onboard graphics will drive a 4k monitor, and unless I have performance issues, I'll leave it that way when I get said monitor.  I just wanted to be prepared to buy a "decent" graphics card if required, but choosing was rather more difficult than I imagined.

Unless you need a GPU that can handle the kind of acceleration that the latest games require or you're into proper animation and rendering, pretty much any graphics chip and a couple of GB memory, even integrated, should handle multiple 4k screens. They passed the threshold for driving even the highest resolution 2D displays some time back. Bandwidth is the main issue, for this retina 5k screen Apple have to bundle two entire displayport channels.

Current generation (and, I think, the last generation) Intel CPUs with integrated graphics can run multiple 4K 60hz displays provided sufficient displayports are available. No need for a separate GPU. If your current setup doesn't have 4K compatible integrated graphics, there are plenty of cheap graphics cards available that will do the job.

WD Red/NAS friendly disks are, I feel, a bit of a con if you are using software raid.
Buy them from two different vendors or at different times so you don't get disks from the same batch, thus more likely to fail at the same time.
And generally, I buy cheaper/more - both my main and backup server are RAID1

Good points about different vendors and batches. I've suffered from bad batches of drives at work, thankfully I don't have to deal with that any more...

The joys of a single 345TB filesystem...anyway...

At home though, I don't use RAID on my backup server as it is a VM running on an ESXi box, so I can't do hardware RAID (at the VM level, and don't want to trust it at the Hypervisor level). As the data is backed up elsewhere too I've opted for simple zfs mirroring instead of software RAID.

Code: [Select]

The ESXi box currently has 32GB RAM, 2x128GB SDD and 2x2TB HDD and I've portioned off a 1TB chunk on each HDD that's visible to my backup VM which sees them as whole drives which zfs is consuming. As you can see the zpool is 95% full.

I've only got one spare SATA port on the motherboard (unless I disconnect the DVD drive) so I was going to add in the new 2TB drive and shuffle stuff around so I use the whole of the 2 of the 2TB drives as mirrors, leaving one 2TB free for other VM images.

Options for lots of storage (my brother and I are going to be each other's offsite backup using rsync...) are:-

1) Get 3 x 4TB drives and use these to replace the existing 2 x 2TB drives. The old 2TB drives I can then use as offsite backups for important stuff by taking one in to work every month and bringing the old one home. This gives me 6TB of mirrored storage.

2) Find a 4 port 6Gbps SATA controller that works well with the free version of ESXi I'm running so I can add more drives as required, there's space for 2 more 3.5" drives in the designated bays and then I've got 2x5.25" bays free that could fit another 3 HDDs. An 8 port controller might future proof it, especially if I want to add more SDDs.

3) Move the bulk backup storage to a separate HP Microserver and get 4x3TB drives for that and do RAID. This leaves the 2x2TB drives free for VMs (mostly my pet projects).

Hmm. Decisions. I'm leaning mostly towards #2 as it keeps everything in one box and costs about the same as #3.

3 years if you've got the money for it, but it depends on usage and number of power cycles. That's partly why I'm looking at doing this as the two 2TB drives in my ESXi box will be 3 years old in February.

I used to grab the SMART data from all the drives every 15 minutes but the scripts that used to do that (it's not so straight forward from ESXi) stopped working and fixing them has been on my TODO list for years.

Surely the point of RAID1 is you don't need to worry about swapping a drive out until it fails and the controller sends you an email?

Quite.  I'd only swap them before this point if I needed more space or if was rebuilding the system and it was a convenient time to replace the disks.  If they run at a sensible temperature and you never power them down, they can keep going for ages.

Once they're out of warranty and the SMART starts chuntering you're at the other end of the bathtub curve and it's important not to take the piss.

I looked into a PCIe SATA conroller and came to the conclusion tbe cheap ones were crud. The optimal path seemed to be buying a 2nd hand Dell/LSi card. But as I wanted (at the time) ZFS to handle the RAID and that meant re-flashing the controller to do non-raid I decided against it. That and the extra power consumption.

You don't say too much about how much storage you need?

Why don't you just throw out the optical drive and add another couple of disks in a new ZFS mirror? My now 2 yr old server has never had an optical drive in it.

If you have drives in the existing pool of the same age from the same vendor, you could buy two new 2TB disks, resilver your existing mirror to have one new/one old disk and your new mirror to have one old/new disk...

I was looking at £120-ish for a reasonable 8 port SATA controller.

You don't say too much about how much storage you need?

6TB or so would be nice and stop me having to mess around with it for another 3 or 4 years. If I effectively write off the current 2x2TB drives as probably dying soon then I'd like to replace with 4x3TB.

Why don't you just throw out the optical drive and add another couple of disks in a new ZFS mirror? My now 2 yr old server has never had an optical drive in it.

I used the optical drive today to upgrade to ESXi 6.0.0, but then that's the first time probably since the initial install. I would like more SATA ports as I've got a couple of ideas for projects that require a reasonable bit of fast storage so I may need to get a few more SSDs in it, and the motherboard's two 6gbps SATA ports are already taken with the existing SSDs.

If you have drives in the existing pool of the same age from the same vendor, you could buy two new 2TB disks, resilver your existing mirror to have one new/one old disk and your new mirror to have one old/new disk...

Thought of that but I'd want more storage, I can't remember enough of zfs configuration to know whether I can do a mirror of 2x2TB + 1x4TB. That way I'd then have a seperate 2x3TB mirror to take me to 5TB total...

You will need to make sure ESXi or whatever hypervisor you are running is compatible with it.

Could you not have done that with a USB stick? dd if=/home/user/Downloads/esxi.iso of=/dev/sdg1 bs=1M ... or if using Windows, http://rufus.akeo.ie/

Take out the ODD and you have six SATA ports to play with, two for RAID0 boot disk and 4x 3TB for 6TB of RAID10 (or striped-mirrored vdevs ins ZFS speak) - that will give you ample performance + resilience.

I think you might be able to do that with some clever partitioning but I'm not sure it's recommended. I know you can certainly use partitions as vdevs to create zpools, what I don't know is whether a logical partition can be made to span more than one disk.

You could always ditch the optical drive now, add 2x3TB or 2x4TB, rebuild your ZFS array in the appropriate shape  to give 4TB usable space and then resilver the remaining 2TB disks onto 3/4TB disks in future to enbiggen it as/when it's more affordable. Probably a good option if you don't need all 6/8 TB right now.

Another Raspberry Pi Zero (#4 in the house along with a Model B Pi) and the 4 port USB hub (that works kind of like a HAT): https://thepihut.com/collections/raspberry-pi-zero/products/zero4u-4-port-usb-hub-for-raspberry-pi-zero

This one is for my 5-a-side (just a bunch of friends, not a league, but still quite competitive) football project:-
* a rugged box hung up on the fence next to the 5-a-side pitch (it's got to survive being hit by a football kicked hard!)
* level with the centre line and above head height on a fence
* sponge/foam padding inside and on the back (the fence vibrates a lot when the ball, or a player, hits it) and bungees to hold it in place
* Two wide angle USB cameras to cover the pitch (and overlapping somewhat)
* 32GB micro-SD card to record everything
* microphone to record sound (the microphones in most USB cameras are crap)
* 2 x two-digit 7 segment displays (4" tall digits probably) for the current score
* buttons to press to increment/decrement/reset the counters (nearest person presses the right button after a goal has gone in, we do kickoffs after each goal so there will be someone nearby it)
* 6 digit 7 segment display clock module to show the current time (so we know how long to go and also make it easier for people to time their turns in goal)
* all powered by a 5000mAh USB power pack and possibly batteries for the 7 segment displays
* 4 USB ports for: camera #1, camera #2, wifi dongle, USB microphone

Not sure whether to have the Raspberry Pi control/power the 7 segment displays or whether to just have a couple of up/down counter circuits and copy the button press pins to the raspberry pi. Probably safer (because of button bounce) to have the Pi control things, that way it knows for sure what the score is since it is controlling the displays.

When the game is finished I press a button to save everything and shut down and it gets shoved in my bag. At home I'll plug the micro-SD card into a reader and copy the files (two video streams, audio stream and the timestamps for goal button increments/decrements) over to a server for post processing.

The post processing needs to:-
* stitch the two overlapping video feeds together and get them in sync (I may have to put a couple of markers, like in the corner of QR codes, on the far fence to make this easier)
* sync the audio (I'll do a clapperboard impression in front of the box before the start of the game)
* rationalise the goal button feed (to get rid of accidental double increments and subsequent decrement or people pissing around with it)
* find the exact frames where the goals are scored (for each goal just display on a web page a choice of 20 frames from the preceding 5 seconds of the button press and I just have to click on the best one or ask it for further back/forward or some in between frames)
* this then creates a graphic overlay in the top left of the final video with the time and current score (bibs vs non-bibs)
* encode it all in something friendly to youtube (so that it doesn't have to transcode it further)
* upload it to youtube
* email out the resulting link to the players

Once I've got the frames where I know a goal has gone in I can also show short snippets of the previous n seconds and then select which player got the goal and who got the assist. For more full opta-style stats (passes, pass completion, unforced errors, length of stints in goal [some people are cheeky and don't do their full turn], etc) I'm tempted to try shipping it off to Amazon Mechanical Turk. I'm sure someone out there will spend a couple of hours wading through an hour long youtube video making notes for a few $.

Anyway, it lends itself to a nice project with lots of incremental steps (start with one camera, no microphone, no 7-seg displays, no buttons, etc) and I get to play with toys and slowly build it up.

Also a nice variation of stuff to do:-
* hardware bodging (rugged container, vibration damping, waterproofing [eventually])
* delicate hardware bodging (soldering, up/down counters [16F628A maybe])
* python coding (Raspberry Pi GPIO pin stuff)
* AV fun (frame extraction, marker detection and splicing, syncing, audio syncing, score/time overlay generation, re-encoding)
* scripting it all together (machine boot into the right state ready for the start button to be pressed, etc) and also the post-processing VM
* networking (it may have a wifi connection so it can get to NTP via a hotspot on my iPhone and get the time right as Pi doesn't have a battery powered internal clock to keep the time when it's not powered on)

Sadly two hour long 1080p video feeds (3.6GB each if 8Mbps) will be too much to upload via Wifi for post-processing whilst I'm in the pub and I don't really want to have to lug a laptop with me to do it, so it can wait until I'm home and do it all whilst I'm asleep.

You can get realtime clock modules for the Pi, might be more reliable than a phone as a hotspot.

Or even use a GPS receiver - I've done that on barakta's alarm clock as a backup in case it comes back from a power failure without networking - but it's probably less good for this application as it can take a while to get a fix and there's no benefit to having a stratum 1 NTP server on a football pitch.

Same goes for MSF receivers - they inherently take over a minute to get a valid time, with the additional problem of being fussy about orientation.

It's only a one-off connection it needs in order to do a single ntpupdate at boot time to get the correct time. It won't need the wireless network during the game. My phone is in my bag which will be close enough for the hotspot to work. Just have to remember to enable to hotspot before the game and disable it afterwards (I don't want to leave it on.)

The Pi Zero will already have a 4-port USB hub on top of it so adding another module may be a pain in the arse if the relevant pins are occluded (it comes without a GPIO header, and I don't want to have to solder one on).

Depending on how much work they need to do I may need two raspberry pi zeros (if it's USB bandwidth and micro-SD card writing bandwidth that's a problem) or a quad core Raspberry Pi 3 (Model B) if it's CPU bound. If I have two pi zeros I'll need to get them to talk to each other and an ad hoc wifi network will work for that.

My point exactly.  A human remembering to do things in the right order is a major reliability problem.  (Though you may not actually care, and can simply turn the phone on and reboot the Pi).

Ah, yes, good point (you can see I've thought this through a lot). More soldering practice and I can mount the header on the underside of the board just as easily.

The 4 port USB hub just uses contact pins/patches so no soldering required.

TBH, it might be simpler to just go straight for the Model 3.  It's a one-off so the difference in cost is marginal (it will surely be dominated by expensive things like the displays and enclosure anyway), you'll have your GPIO header ready to go, and it means you can do away with the USB hub entirely.
Title: Re: Bought any computing stuff today?
Post by: Greenbank on 07 October, 2016, 02:19:29 pm
£15 (£4 for Pi Zero + £10 for USB hub and £1 for a header[1]) vs £30 for a Pi 3 (Model B).

It may end up being a Pi 3 but I'd like to try building it with a single Pi Zero first.

Display is likely to be £35 (4 x 4" high 7 segment displays plus a couple of controller chips and resistors).

Enclosure will be a few quid and bodged. The non-waterproof version is probably just going to be a tough metal grille bent into place with a few larger holes cut out so the displays can be seen easily. The waterproof version will probably just be the whole lot in a clear perspex cover sealed with silicone and behind the same grille.

1. Yes I know they are available elsewhere for much cheaper.

We've found that, as per the manual that I've now read, if you watch, you can make little adjustments that means more is accessible. Our house is very cluttered, and the boys and i are blind to mess. Moving a box here, a music stand and a chair there... Now she's cleaning under our 11 year olds bed. The amount of hair and filth is astonishing, given we'd already got a Miele vacuum that was used regularly-ish. The difference is that now we trigger the Neato when we leave the house and it's scheduled for when the boys are going to bed - in eco mode is quiet enough that it didn't disturb them. It feels like we're on top of things as opposed to being miserable cleaning on Saturdays.

Am still at the infatuated stage, because of the amount of crap every time it's used. Maybe I'll be less so when we're in maintenance phase. Seeing it navigate through the tiniest of gaps, and find its way home is really cool.

A tangerine 7" 8GB Amazon Kindle, because they're on special (presumably for Black Friday) at £29.99 each, the 7" and 8GB version because feeping creaturism kept on kicking in, and I'm just going to play with it, and tangerine on the basis it makes it harder for me to lose it somewhere around the house. ;D

(I've got a pink Q2 Wifi radio for similar reasons, although the pink one was also slightly cheaper than more conventional colours like black).

I haven't really looked too hard at how difficult it will be to root it, and install something more useful like CyanogenMod, but I'm assuming that even if no one has worked it out for the current version of software, there will most likely be a solution along eventually !

A tangerine 7" 8GB Amazon Kindle, because they're on special (presumably for Black Friday) at £29.99 each ...

For the money, it's impressively good.  I can fairly easily spend more shopping for groceries in Sainsburys!

It doesn't want to play the audio on one of my ripped AVI files (but it's hardly unique having that sort of problem), and somehow I managed to crash it, when the alarm went off, but otherwise it massively beats the performance of my old Nexus 7 that was a lot more expensive when I bought it.

Without a Micro-SD card it would rapidly run out of storage, but I have plenty of those, so that's not a big issue.

Surprisingly, it came with a 1A USB charger, which I didn't expect.  Several devices I've purchased recently have only provided a cable, so for a £30 tablet, finding a cable and a charger in the box was unexpected.

The adverts are a little annoying, and there's nothing spectacular about the facilities it provides, so I'll probably put another distribution on it, assuming I can work out how to jailbreak it.  Does anyone have any particular thoughts on what software versions are good for tablets, or should I just go for the current version of CyanogenMod ?

Snagged 3x cheap (new) 4GB Unbuffered ECC DDR3L DIMMs from fleabay.
The intention is to give the backup server a reasonable amount of ram (+4GB) so if it's ever relied upon, it can at least manage a bit of ZFS caching.

I had planned to pop the other two sticks in the main server, but it looks like my last updates have relieved memory pressure and I don't actually need it.

Not today, but yesterday, another two U2F keys.

Now Facebook supports two factor authentication using Fido U2F keys, it's slightly more useful than previously, when Google was one of the few mainstream companies that did.

At £8 each, they're not too unreasonable, and with several of them, I can lock one up securely, just in case, and always have a couple of others to carry around (and risk losing).  (I've got printouts of single use numbers, too).

Slightly annoyingly but understandably, by design there is actually no way to identify each key uniquely (like a serial number), so I've had to sticker them!  I think I should be able to identify each one, by signing a known phrase, which should be unique but produce a repeatable result.

Also not today, but a Creative sound card for the big bugger upstairs.  Upgraded the sound to 5:1, which uses one of the HDMI ports on the graphics card.  Problem is that this makes the graphics card think it's got a second monitor attached, to the considerable detriment of graphics performance chiz.

A 525GB "hard disk" (an M.2 2280 format SSD) for my Sony Viao flippy foldy touchscreen laptop...  Obviously the scary bit was getting inside it to swap the drive, but we both survived.  The only problem so far is that Acronis screwed up the cloning, and wrote two partitions the size of the original drive, and ignored the rest of the space.  Windows partition management tools won't expand the partition to fit the space released by the deletion of the spurious duplicate partition, so I suppose I'm going to have to buy something to fix it.  The original drive will live on as another 128GB USB stick, albeit a thin flat one on a flexi-cable.

A set of thermostatically controlled fans for the rack so I don't have to anticipate warm days and open the door.

In tests the rack-top fans at full pelt drop the temperature of the NUC in the top of the rack by ten degrees. But the two servers only by around two degrees.

The servers were rebuilt from tower cases which had 4x 120mm "quiet" fans. In the rack cases they now have 1x 120mm "quiet" fan blowing air across the mobo and 2x 80mm regular fans blowing air over the disks. Hence mobo and CPU temps aren't dropping much.

Next payday I'll replace the "quiet" fans with some that have a little more gusto and add some 60 mm fans to the front of the cases.
Title: Re: Bought any computing stuff today?
Post by: Kim on 07 April, 2017, 02:21:27 pm
The most important thing I found for keeping things cool in my rack was careful management of the airflow through the rack.  I've got a pair of 140mm silent fans pulling air out of the top of the rack, and air comes in through an open hole in the bottom (along with dozens of cables).  No vents in the doors or side panels.  A pair of 120mm fans in a 4U blanking plate occupy the lowest position in the rack, moving fresh cool air to the front section.  Then, and this is the important bit, I've filled the rack with equipment and blanking plates so air can't circulate between the back and front other than by being blown through equipment by its fans.  So everything that breathes is breathing cold air.  Non-rackmount bits and pieces are on a shelf at the very top, which doesn't short-circuit the overall airflow.

For noise and reliability reasons I've gone to a lot of effort to avoid any fans smaller than 80mm (and most of those are under thermostatic control to keep the noise down).  This seriously restricts your choice of computer cases, switches[1], etc.

Thanks for that Kim. What kind of CPU/MB temperatures to you see?

Similarly to yours,  my rack is fully enclosed and has a hole in the bottom - which I can close up during winter. Using a forward facing fan plate at the bottom to push the fresh air to the front sounds like a good idea.

The only slight spanner in the works is the cases I've got*: https://www.xcase.co.uk/collections/4u-rackmount-cases/products/x-case-xn402-front-access-4u-short-350mm-deep?variant=17249715141
They draw air in from the left and expel it to the right, which kind of knackers up the front/back (al a datacentre) ventilation.

At the minute there's a 1U shelf at the top of the rack, which is home to a passively cooled NUC, 2x RIPE probes (stacked on top of each other they are about the size of a rubix cube) and the cable modem. Underneath them is a passively cooled switch, followed by 2x 4U servers. Sitting on the bottom of the rack is a tower form factor UPS taking up a ridiculous 7U.

Eventually I'll replace the UPS with a rackmount one, at which point I think it's worth while moving the shelf down to the bottom.

In fairness, the always-on server doesn't generate too much heat to begin with and temps currently tick along in the low thirties. The other server is only switched on for the backup window and that doesn't seemt to be on long enough to cause any increase in temperatures. I guess...

a) I just like having some contingency for dealing with those rare hot days
b) I'm planning ahead** for when I add a couple of switches and a couple of Dell R210 IIs*** for some lab work

*They fit comfortably in a 600mm deep rack and I like the front facing connectors as it's difficult getting to the back of the rack
**wishful thinking
***They are shallow enough to fit

Room temperature from a sensor at chest height is currently 25.1C (The sun's been shining through the window for a few hours, but not on the sensor itself.)

Air at the bottom of the rack (sensor in front of the fan at the bottom) is 23.1C
Exhaust air (sensor above the top fan) is 27.4C

Server in the middle of the rack (Standard PC hardware, Celeron G1840 2.8GHz CPU, 3 active spinning-rust disks (and a couple in standby, and a pair of SSDs) in an completely overkill case (http://www.logic-case.com/products/rackmount-chassis/4u/4u-short-length-server-case-w-16-x-35-hot-swappable-satasas-drive-bays-6gbs-minisas-+-2-x-525-bays-sc-4316s/)[1]) reports:

Sensor 2 43.0°C

(Your guess is as good as mine as to what any of these sensors actually are.  Seems safe to assume the hot ones are the CPUs)

UPS near the bottom is reporting 35C on its front panel (the NUT driver doesn't report temperature correctly).  That's a 1500VA unit that's just ticking over with a claimed 145VA of load, and has had a fan transplant (and subsequent buzzerectomy[2]) in the interests of quiet.  It ran a few degrees cooler with the original scream-o-death fans.

There's also a passively cooled Ethernet switch, ADSL modem and PoE injector[3].  And a couple of wall-warts lurking at the back powering a 1-wire switch and the main fans.


Things that don't ventilate in the right direction are annoying.  Previous UPS was a skip-dived 3000VA tower beast, which did a passable impression of 5U if installed on its side using sturdy plywood shelf technology, and had a reasonable 120mm thermostatically controlled fan that only made proper noise if you plugged a kettle into it.  Unfortunately both the air intake and outlet were on the back panel.  I bodged a bit of extractor fan ducting to feed it cooler air from the front, but after about 12 years and two expensively large sets of batteries I retired it in favour of something smaller that could communicate its status without unobtanium proprietary software.


[1] I wanted 6 swappable drive bays, 80mm or larger fans (which pretty much implies desktop hardware), and a depth that would fit in the rack, so there weren't a lot of options.  I quite like the way this one has a row of fans in the middle - I've left the rear panel fan mounts unpopulated.  I've ignored the original hot-swap fan power wiring in favour of a g4m3r d00d thermostatic fan controller in one of the 5.25" bays, and attached the sensors to various heatsinks.  They're currently ticking over at ~1500RPM and keeping things in the 28-33C range.
[2] A tedious saga in which it turns out that it goes into alarm if it doesn't detect the fans running at >3000RPM, using a sneaky two-wire method rather than the usual tacho wire that would be easy to spoof.

Might not even need replacement, if it's the solder itself that's the break.  They all use that lead-free rubbish these days.  A dab with the iron and a bit of fresh solder might be all it needs.  Or you might find the board itself is broken and have to get creative with bodge wire and hot glue...

With the currently underway Ransomware (http://www.bbc.co.uk/news/technology-39901382) attacks hitting a lot of places, even though I haven't been hit privately or professionally, I'm still feeling particularly paranoid, so I've ordered a GL-AR300M mini PC thingy. Its pre-installed OpenWRT should let me firewall the house's network somewhat more effectively than the fairly limited and fiddly firewall configuration in my RTEMS based ADSL modem and router.  It's not dramatically different from the Raspberry Pi that I've used for other things, but does have more networking hardware built in, and a pretty box, as well as what should be a more sophisticated WiFi interface than the PCB antenna on the Pi Zero W.

This is about the biggest, most expensive and complicated version that they do.  It's got a 650MHz CPU, 128MB of RAM, 144MB of Flash and dual external WiFi antennas.  It's a little bit over 10cm across because of the antennas, the box alone is probably 5cm × 5cm × 2cm.

Just bought a 2TB Hitachi drive to re-build my CentOS7/Roundcube webmail server.
This was a nice new Gen8 HP microserver, but I just grabbed a random HDD from the Teetering Pile o' Old HDDs to shove in it in my enthusiasm to get it up and running.

Following a power outage, the drive never properly spun up again, and the box is now dead.
The machine was only ever an experimental build, so no great loss.
But I'm already getting gripes about when will the webmail be back up.
Bugger off and use the IMAP clients I set up for you all!

Anyways, a server re-build is on the cards, and this time I'll take a disk image once it's up and running.

I upgraded the fans in both home/backup server over the weekend so hopefully they will stay cool when summer finally arrives.
When I powered on the main server, the virtualised pfSense firewall stalled booting, because it had lost one of it's interfaces. The IGB driver logged "probed wailed with error -13" for one of the ports, so I'm assuming hardware failure. If it was a driver problem, I'd expect all four ports to be effect.

I've vLANned the b0rked interface over one of the other ports for now and order 2x pre-owned Intel Pro/1000VT quad port network cards. I'm thinking eventually I might get some static public IP addresses and start running a second virtualised firewall on the backup server for redundancy.

So.. anyone want an Intel Pro/1000VT quad port gigabit network card with only 3 working ports?

A 200kHz single channel scope, for £16 !

I'm not expecting a great deal, the bandwidth is low, and it's a single channel with no external trigger, but it should be fun to experiment with. :)

I've got fed up unmounting the Fly6 and Garmin Virb cameras from the bicycle, so that I can plug them into the NAS to charge the batteries and dump the video.

I can mount this stack of cards next to the bike, plugged into the same mains supply as I use to charge the Exposure lights.  With a little bit of bash scripting, it should be able to recognise that the devices have been plugged in, and start a transfer over the network to the NAS.  The Unicorn PHAT will allow me to display some basic status information about the devices plugged in, the networking connection, disc capacity etc.

It's always amusing that almost every extra board you buy for a Raspberry Pi Zero W, costs more than the processor board itself !

Just finished building mine (mildly irksome tiny pads on the through-hole stuff that a beginner might find challenging, it benefits from the flux pen treatment, but no real surprises).  The case is some of the cheapest nastiest self-untapping plastic rubbish you're likely to come across, but it does appear to work...

(http://www.ductilebiscuit.net/gallery_albums/random/2017_06_06_20_57_20.sized.jpg)

Seems to agree with the Rigol to within the sort of precision you can reasonably eyeball on such a tiny display (it doesn't do measurements).

Shame there isn't space for a 9V battery inside the case really, though it's drawing the best part of 120mA, so it wouldn't last long.

On the previous version you could hold down the OK button while the timebase was highlighted to turn a display of the values on or off. I bet this has got something similar.

Yes, holding down the OK button for 3 seconds turns the display of values on and off. There are various "hidden" functions like that, centering waveforms, even save and recall of waveforms by pressing combinations of buttons.

SSD arrived today and took about 90 mins to clone, say 2 hours total. Physically it went straight into a 6 year old Presario CQ61 with SATA 3 altho' the first start up was wobbly.  I've done quite a few starts since and boot time is greatly reduced and it's loads faster doing everything.  Runs very much cooler too.  Money well spent.

Now't special. Just three quality pre-loved SFX power supplies at a bargain £9 a piece. Two to use in my servers, one to keep as a spare (..they are second hand!)

When I rebuilt the main/backup servers into rack cases, the ATX PSUs were a tight fit and consequently I broke the SATA connector on one of the hard disks.
Said disk still works, but at some point I'll replace it just to be on the safe side.

I'm eyeing up some cheapish SSDs so that I can have mdadm RAIDed boot disks. Not rich enough to justify it yet, but as I've once lost the home network thanks to a dead SSD it needs doing.

It's only 750VA (where as the existing mini tower one is 1300VA), but given that the Rack's power draw is ~60W that should be more sufficient and a bit more energy efficient.

I've been contemplating a cheap hypervisor with enough oomph to perhaps run 8 or so small VMs for quite sometime. After considerable waxing, waning and deliberation a dual socket Supermicro board of some vintage, complete with a pair of Xeon L5520 (https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+L5520+%40+2.27GHz&id=1260&cpuCount=2) CPUs has been requisitioned.

It has lots of RAM slots which is good, because whilst 4GB DDR3 ECC registered dimms can be acquired for £notmuch, 8GB equivalents are £alot. Of course all those RAM slots come at a price - and that in this instance is a bloody big board. So now I have to find an E-ATX suitable rackmount case that is less than 484mm deep, with enough 120mm fan mounts and without silly-sticky-outy handles that foul that brackets on the server cabinet door. Such cases don't seem to exist - which means I can see the dremel being utilised to fashion something suitable.

On the bright side, I've two disks, a PSU and some other bits ready which should make this the thriftiest hypervisor by far. Save for the running costs. Which will be mitigated somewhat by restricting it's uptime to a few hours each week.

Not bought, rather blagged.

Our office is moving, and tomorrow is the last day at the old site.
Today was the ransacking and plundering of anything not nailed down, or marked up for transferring to the new office.

The IT cupboard was one of the first to be ransacked, and I came away with a Netgear GSM7224 24-port gigabit managed switch, which will replace the switch which died it the IT Meltdown I had earlier this year.  It's currently screaming away under my desk, having been factory-reset and then RS-232 consoled onto it to set up it's IP address.

I've set up the homenet VLANS and it's all working rather nicely, if a little noisily.
It's not actually in service yet, it's just hanging off the network for config porpoises.

I really need to do something about the wee screamy fans though.

Yes, rackmount kit is noisy because rack space is priced per-U, so everyone makes stupidly flat products.
So the fans can only be about 20mm high, and you then need lots of them spinning at 10,000RPM to get any airflow.

These fans have shot bearings, and simply doing a like-for-like replacement for new will help.
Otherwise, I may modify the case with a HBFO slow quiet fan on the top.

A Magic Trackpad. It doesn't disappointingly do actual magic (as far as I can tell, I've yet to find the Metatron's Cube gesture, but I'm working on it). Actually, I didn't buy it, it was a present.

I have a Magic Mouse for the finer work, but I do like the trackpad on my Macbook. I have to say it's rather spiffing for general scrolling and clickery but I'm running out of desk space.

For Defender you just needed twelve double-jointed fingers. Leastways you did to crack hyperspace on Level 142 when you'd run out of smartbombs. I think the highest score ever achieved was 33 million and took 38 hours to get there. I only played Defender in the chippie while I waited for my fritters and chips. They were usually ready in five minutes. There's no such thing as too much starch.

Anyway, owing to Magic Trackpad, I just learned that Apple trackpads have two levels of click (three if you count the tap). Despite owning a Macbook, I never knew that. It's another awesome thing I have no particular use of.

The latest blaggage was from the in-use server room.

Everyone is downstairs in the kitchen eating sossidge rolls and sammitches and drinking boozahol, prior to being kicked out at 1pm to allow the removal dudes to get on with it.
But also, the IT dudes are getting on with it.
The dude is in the extra-double-triple locked server room, stripping it down.

The one I've bought is based on an ESP8266[1] (so it can speak WiFi directly).  My plan is to modify the firmware to raise the PWM frequency to about 10kHz (barakta can perceive the flicker upto about 6kHz, so the default 500Hz is no good), hack around the resulting instability, then see about re-writing it for stand-alone colour temperature changing according to the position of the sun behaviour.  Anything else is a bonus.

I'm trying to keep the internet-of-shit factor to a minimum - it should always come on on boot-up.  Nobody wants to have to use an app to turn their lights on and off.


[1] https://authometion.com/shop/en/home/14-lyt8266-mounting-kit.html - it's expensive (moreso if bought pre-assembled) but if it works, I'm happy to pay a premium not to be locked into, well anything.  If you can easily write your own firmware, it doesn't matter what the manufacturer does in future.

Yes they are. The ones I bought are just white ones not vary coloured. Via the Amazon Echo you can change the brightness and turn them on and off but you cant change the colour temperature (if you have coloured ones you cant change the colour). You can dived the lights into different groups and control them by group name. If you want to change temperature or colour you need to get the Philips home hub and get Alexa to control them via that.
For what we need at  present the inbuilt home hub in the Echo Dot has sufficient functionality.
I'm pleased with it and Mrs Pcolbeck is too. Currently we keep asking Alexa random things and turning the lights up and down then giggling. Its like being in Start Trek. I'm tempted to change the wake up word from "Alexa" to "Computer".

Luckily Amazon are doing a buy three items get the cheapest free on a lot of Philips Hue stuff at the moment. I'll reuse the no adjustable bulbs where the temperature doesn't matter such as in the bedroom.

The one I've bought is based on an ESP8266[1] (so it can speak WiFi directly).  My plan is to modify the firmware to raise the PWM frequency to about 10kHz (barakta can perceive the flicker upto about 6kHz, so the default 500Hz is no good), hack around the resulting instability, then see about re-writing it for stand-alone colour temperature changing according to the position of the sun behaviour.  Anything else is a bonus.

I've got a fair way with LED 5050 strips to colour cast the room based upon time of day. I'm using adafruit feather huzzahs or Wemos D1 Mini Pros for processing, and both have ESP8266 onboard. A quick dash out to wunderground api and I know the sunrise/sunset times for the day. I use similar code for Frebber's nightlight, which sets max lux levels based upon time of day, or the blinds which track the sun.

Its all automated using an NTP time signal. Hook me up if you get stuck.

That particular project has been thwarted by inadequate hardware:  The lamp can do a respectable warm-white and all the garish RGB colours you can wish for, but subtle changes in colour temperature aren't really viable.  More disappointingly, the white LEDs are nowhere near bright enough to light a room with (it's about right for a desk lamp).  And the ESP module seems nonspecifically dodgy, vis intermittent flash problems and the WiFi only working in access point mode - I need to moan at the supplier about a replacement.

A brace of magic security cameras. After three years of deliberation (the old alarm was stripped out of the Asbestos Palace when it was refurbished). I don't like alarms, I figure all they're good for is disturbing the neighbours. Unless you pony up for the full security detail, I don't expect the police will rush around, and anyway, any practised burglar will be long gone before anyone turns up. There's the old alarm box outside and it looks like the sort of house that would have an alarm, plus there are lights on timers etc. A brief stroll around after dark makes it obvious which houses are empty. I'd make a great burglar. Hmm.

Anyway, we both travel a lot, and often out late in the evenings, the street lights go off at midnight and thereafter it's completely black, so it would be reassuring to know to house is still standing and if something does happen we might at least have some evidence. Though if the police treat any video the same as they do bike cams, I might not get my hopes up.

OK, I confess, it's mostly so I can spy on the cats and capture evidence of their many nefarious misdeeds. I tried to learn the psychic art of remote viewing and failed, so this is the next best thing.

As well as an NVIDIA GT1030 gpu, to drive the monitor, as the onboard graphics on my motherboard couldn't drive the screen at the required resolution.

Still to calibrate the screen using my spyder2 express colorimeter , but apparently the screen has been calibrated by BenQ themselves to an average Delta E of the sRGB Gamut of 1.1311. Not bad for a £280 monitor!

Make sure they've got the strands in the right order too.  Sparks aren't known for their understanding of RF, and failing to follow the standard colour code (getting the pinout right, but splitting signals across different pairs) is a popular way of cocking it up, and one that can be tricky to detect without proper test gear or Mk 1 eyeball access to the punch-downs.

The game SSD on my home PC is completely full of one flight sim (DCS World) and the updates were failing. Can't have that.

At the moment the main server is using a single SSD recycled from something else and the backup server uses a 500GB spinner.
In the near future they will each sport a pair of 860 EVOs (250GB variant) in some sort of RAID so a failed boot disk doesn't bring the server to its knees (... not that I've already had experience of that  :hand:)
I chose the Samsungs not for performance reasons, but energy consumption based on the servers typical workload (a constant trickle of read/write).

I've just ordered the 1U case, pico PSU, el cheapo 120 GB SSD and an Asrock J3455B-ITX mobo as a replacement to the Intel E3815 Atom NUC that sits in my DMZ. This is used for hosting demo web sites, hosting git repositories, running a jenkins build server that automatically deploys the demo websites and then deploys them live at the push of a button. It also runs a range of other things in tmux sessions, with the advantage I can SSH into it from anywhere.

Thing is, I now need to work collaboratively on some documents and run a shared calendar etc.. RunningNext Cloud with Only Office on the NUC was going to be asking too much of it.
The NUC might be offered for sale soon - ideal for anyone who wants a low power/always on server to do DHCP/DNS etc.

A little Bluetooth nuggle for my headphones. I was just going to buy some wireless headphones but they seem to waver between cheap and likely shit and ouchingly expensive. I lose headphones at a rate of about once a month which could promise to be an expensive habit very quickly and I'm happy with £30ish Sennheiser earbuds (I buy a couple of pairs at a time, may as well be prepared).

I was pretty blase about buying this (just another laptop) until it arrived today. I'm bowled over - smaller & lighter than the outgoing macbook air, faster than my main quad core 2013 i7 iMac, gorgeous screen, touch ID login just works, sound is better than adequate.

As mentioned, the evil geniuses (well, one called Vivian) at the Apple store made me buy a pair of new iPhones. I felt a bit bad at handing her my very grungy iPhone 6, which in the surgically clean retail splendour of the Apple Store looked a little worse for wear. I could only apologize greatly. I'm surprised she didn't get out a pair of latex gloves to touch it. Even my wife backed away a step. We'd only gone in to ask about a battery replacement so I wasn't planning on exposing it (it's been in a silicone case since forever, and all the grunge had levered its way behind it – and yes, I'm talking about the phone). On the plus side, it hid all the dinks and scratches.

But anyway, nice though it is, bigly! Sat on my desk next to my mothership-issued iPhone SE. I don't have pockets big enough to hold a dinner tray.

I'm not 100% sure that this can be described as 'computing stuff', but it's certainly related.  It comes under various descriptions, but one of the most common designations is LCR-TC1, and it's variously referred to as a Multi-Function Tester or Transistor Tester.  I just got it, although I ordered it a few days ago.

(http://balius.sp.ph.ic.ac.uk/~timo/stuff/vsmall.php?vsize=300&file=IMG_20190323_193919_crop_adj.jpg) (http://balius.sp.ph.ic.ac.uk/~timo/stuff/IMG_20190323_193919_crop_adj.jpg)  (http://balius.sp.ph.ic.ac.uk/~timo/stuff/vsmall.php?vsize=300&file=IMG_20190323_201842_crop_adj.jpg) (http://balius.sp.ph.ic.ac.uk/~timo/stuff/IMG_20190323_201842_crop_adj.jpg)

If you plug any small electronic component into it, it will determine what it is, and give you the basic parameters for it.  It seems to be able to identify single cell batteries (no more than 4.5V), capacitors, resistors, inductors, diodes, zeners, bog-standard bipolar transistors, thyristors, triacs, JFETs, MOSFETs and IGBTs.

You can probably buy similar unit, without a case or battery, and with a B&W screen for as low as £7 from China, and if you're willing to wait you can get this one with an internal USB charged Lithium cell and case probably for £12 on Banggood, AliExpress of eBay.  On eBay, I paid £15 with about 1 week delivery to Argos Click'and'Collect).  Now I know what to search for, they are also available for £18 on Amazon, with Prime next day delivery!

It's not terribly accurate, especially with some of the slightly more exotic parameters, like a capacitor's ESR, but certainly provides approximate values.  If you want to measure a zener, with a reverse voltage greater than 4.5V, there's a pair of special connections for that, which will supposedly work up to 30V, although it failed to measure a 29V Zener in a YouTube video I saw (but did work with a 20V Zener).

I've tested it on a few random capacitors and resistors, and it generally gives a value within the quoted error range of the components, and happily identified a MOSFET, although it measured an RDS variously between 0.2Ω and 0.4Ω, when the datasheet says a typical value of 0.065Ω and maximum of 0.075Ω.  However, for a unit costing £15, I didn't expect a great deal of fidelity!  Internally it's relying almost entirely on an AVR microcontroller for the measurements, and the ADC on that is optimistically only 10 bits typically over 5V, so naively that's resolution of 5mV, but I suspect other factors affect its ability to measure some parameters.

Quite a cool, neat little gadget. :thumbsup: :)

I've got an older variation on that theme.  I really like the ZIF socket for bunging random components in, and it's replaced my cheap Chinese LCR meter for quickly identifying random resistors without reliable colour vision.  One of my favourite functions is being able to read the ROM address from DS18B20 temperature sensors, for ease of identification or hard-coding in embedded things where a discovery algorithm would take up too much space.

(http://www.ductilebiscuit.net/gallery_albums/random/2019_03_25_12_14_21_001.sized.jpg)

Looks like yours has a much better case design, particularly with regard to accessing the lever on the ZIF socket.  I keep not getting round to trimming the plastic on mine so it's a bit less fiddly to release if you fully depress it.

It's also got basic frequency and voltage measurement, a basic frequency generator, and (more usefully, since I don't have something better that will readily do it) the ability to generate a PWM signal at arbitrary duty cycle.  Mine doesn't have the zener feature - it just identifies them as normal diodes.  Given how handy I've found the 15V diode range[1] on the 121GW multimeter, that sounds well worth having.

A lot of functionality in a cheap little gadget.  At a price that's well worth it for anyone starting out in electronics (I expect the actual *testing* of components is a lot more useful if you're not so confident about what you're doing, particularly when it comes to troubleshooting circuits), and useful simply as a random component identifier for tidying up after breadboard sessions.  The precision isn't brilliant, but it's perfectly sufficient for "what is this?" and "has this lost its magic smoke?".


[1] A niche multimeter feature that really shouldn't be:  Extremely useful for testing series LEDs, as well as zeners.

Just installed new Asus motherboard,  16gb DDR 4 memory and a six core AMD Ryzen 2600x CPU as a result of old i5 ddr 3 Gigabyte motherboard suddenly dying. Must say most impressed with the performance of what is a modern mid range cpu which is similar to current gen Intel I5 7700 (but apparently 3 x faster on multithreading)  and great vfm. but could have done without the expense just atm. New board has a 32Gb/sec M2 slot which I will be populating in due course. I was most hacked off at not being able to find a replacement Mobo for the old set up which still seemed capable of tackling just about anything albeit with a 4 core cpu. Also disappointed that local supplier wanted £70 more for same new kit but with a cheaper motherboard

AM4 motherboards are a little tricky at the moment.  AMD promised that the AM4 will be supported for several years.  Sadly that has resulted in too many processes for the space in the bios chips. So with the Ryzen 3000 series fulfilling AMDs promise to run on AM4 there are bios updates for old boards like mine to support the new processors. However this means that the lower end processors are no longer supported and some motherboard features such as raid stop working.

So I was pleased when I noticed that my motherboard, MSI B350 Tomahawk Arctic can support the latest processors I was little disappointed that would cripple the board even thought it would make no difference to me. MSI have re-engineered their motherboards.  There is for example MSI B450 Tomahawk MAX. The only difference for the B450 Tomahawk is a larger bios chip.  So this new motherboard can support every AM4 processor from the lowly AM4 Athlon or APU to the latest Ryzen 9 3xxx.

I should not grumble. Intel nearly always require a new motherboard for a new processor.

The stock cooler is struggling a bit in my system I assume partly due to the restricted floor standing location available for the pc as I am not deliberately overclocking. I bought some 140mm Corsair magnetic lev case fans to see if they would help. In the event I was only able to fit one of these on a side panel.  :hand: . These fans have a large operating range via PWM. Although fairly quiet at low RPM they quickly become something akin to a jet aircraft taking off, in addition to which, there is a constant low level motor whine. So, althought they are effective at moving large volumes of air around, and will probably prove to be very robust, I am a tad disappointed. I have now therefore ordered a new, rather expensive, Noctua designed cpu cooler in the hope that this sorts the issue.

I suppose I didn't _really_ need to go single mode because the run was measured at 542m but the single mode cable was cheaper. Plus I've found some 10Gb transceivers which should be compatible for under £100 each so... this could work!

Sorted my issues by relocating the new 140mm Corsair fan to the top of the case in extract mode and replacing it with an original 3 pin 120mm fan. I have ordered some semi rigid PVC dust filters which are supposed to help with this issue. Seems the new fan was resonating with the panel despite application of rubber washered mountings thereby producing its banshee wail, but now is very quiet. I have also installed a new Noctua extract fan to the rear of the case. CPU temps are now much lower with the stock cooler, so the new cpu cooler will be a bit of overkill, but never mind.

Spurred on by that I just spec'd out a similar machine and was surprised at just how cheap it was. I'd expected to be paying at least double, which only goes to show how out of touch I am with it all.

I remember buying my 486DX2-66 with 8MB RAM for £1000 in my first year of Uni back in 1994. That was my entire student loan for the first year and I remember walking through some dodgy bits of Sheffield (down by the station but lots of it was dodgy back then) with £1000 in £20 notes in an envelope in my pocket feeling rather uneasy.

Amazing isn't it. I do router virtualisation for self study and testing out configs before using them on clients networks. The old Cisco virtual images used to take up hardly any RAM or CPU but the new stuff requires 1 vCPU and 5-8GB RAM per router. Then there's management appliances etc. Oh and vMware with vCentre and NSX etc. A laptop just doesn't cut it for this kind of stuff any more and I had to bite the bullet.
Staying one generation behind the latest kit gets you an amazing amount of bang for your buck.
My electricity bill may get somewhat bigger though ....

An Ethernet cable cover is shirely the boot that stops the tab snapping off the RJ45 when you wrestle it from the other hissing cables...

I have a big box and one large drawer of ethernet (and other deprecated cables) folded into n-dimensional brane space (say what you want about Apple pricing, but they fold 'em up neat). There's some incontrovertible urge to hang onto this stuff in case I one day suddenly myself having to cable a large office block.

Of course, it's a rule that the one you want is the one you won't find.

I hope Cisco took whoever put the mode switch in that position on the front of the chassis out the back and gave them a serious seeing to.
That one caused me and network engineers all over the world much pain until someone noticed what was going on.

There was a DEC VT320 in my attic for years until Mrs Pcolbeck made me dispose of it a couple of years ago :~(

When I was a PSO, we had a Wyse VT-120 clone liberated from the Physics department skip, that lived on top of the fridge, logged into a Linux box in another room, running BitchX.  This enabled us to have put-the-kettle-on / does-anyone-have-some-cash-for-the-meter / come-here-and-remove-your-festering-pile-of-ming-from-the-sink-you-boabword conversations up and down the stairs at sensible student times like 2am, and with appropriate use of all caps and multiple exclamation marks, without waking our gratuated housemate who had a job that required audax o'clock starts (because BloodyTrains).

When barakta came along, this Just Worked for her, and so it came with us when we moved out, and was still in service until about 4 years ago, when it was replaced by a Raspberry Pi and 10 quid from eBay monitor.

The great thing about a serial terminal was that you could turn it on from cold and hit <ctrl><L> and be at a working IRC window complete with scrollback in about 5 seconds.  The Pi does somewhat better, by powering up the monitor as you walk into the room, but at a cost of a couple of watts quiescent power.

I imagine we were one of the last users of the things for some pratical application that was neither retrocomputing, art, nor control of some vastly expensive piece of industrial/scientific/banking equipment from 1983.

All Cisco switches and routers still need a serial console to give them a management address at least so you can SSH them (unless you POAP boot them which no one ever does unless you are building a fabric and even then its a PITA as they end up with random IP addresses). So there is a big market for USB to serial port adaptors for network engineers since they stopped putting RS232 ports on laptops.
Luckily these days quite often I get someone else to do that what with apparently being a network architect and not an engineer any-more (get to sit in a nice warm office or at home with RAS whilst someone else goes down to the datacentre racks).

Yep, serial's going to be with us for a long time yet.  Maybe not full RS232 like on network kit, but serial comms at TTL levels remains standard for talking to microcontrollers.  For bonus points, you get to play what-USB-dongle-does-the-timing/handshake-properly-for-this-fussy-piece-of-hardware while hoping that there isn't a pirate Prolific chip involved that will get bricked if you plug it into a Windows machine with the official driver.

At least the 25-pin D connectors have mostly gone.

Fortunately Concur and emailed receipts has made the scanner unnecessary.

Got an APC C5-650 UPS from my dad when visiting last week, he'd rescued it from a skip so it was free. Battery looks in good condition so no idea why it was thrown away. Will test it out when I'm in long enough to keep an eye on it.

I don't care if it can only provide a fraction of its stated capacity, I only need it to cover the very occasional (once every 3-4 months or so) blip in the power supply that's just long enough to cause various items (ESXi box and NAS mainly) to reboot. Also ordered a 4 way extension block with an IEC C14 socket on it to plug into the back of the UPS rather than having to faff with recabling everything.

Terrible scheduler on Dec-20s.  Great for teaching Basic etc. If a process was  interrupted for I/O it was placed at the front of the queue so you get a seemingly responsive system when you are typing a line of code. Or run you latest "hello world" job.  However if a process used it entire time slice it was placed on the end of the run queue.  So if you write a program that actually does some work it becomes the lowest priority task in the system and runs accordingly. In brief loved by users doing Programming 101 hated by every other user.

Works a treat and so NAS box, ESXi server and switch have been moved onto it. Should also put one of the monitors on it otherwise I have to open the laptop if the power does ever go and I want to log in and shut things down cleanly.

No idea how long it would last but it certainly lasted >30s whilst I was moving some cables around.

Also meant I could plug in an inline power meter to give me an idea[1] of the draw of the home office.

170W for two 23" monitors, work laptop, NAS box (nigh on idle), ESXi box (nigh on idle), speakers, HP OfficeJet printer, UPS keeping itself topped up, MSI min-laptop keeping itself topped up.

You'll probably die of slow frustration. In the meantime, Microsoft will farm and concentrate that slow seep of frustration and pipe it back to Redmond.

2 off Adaptec 6405T RAID controllers.  These should speed things up but that's only a bonus, the reasons are:

1) Mint can't read my windows partition because it's a SATA RAID1 off the motherboard and there's no frikkin driver for Linux.
2) The sheer unmitigated abominable detestable nightmare I went through to set up a Linux software RAID1 for my Mint installation is the kind of horror story I wouldn't wish on anyone.  I mean, to set up a Windows software RAID is a few clicks.  To set up a chipset fakeraid at Windows installation involves popping in the floppy at the appropriate point.  The instructions for setting up a Linux software RAID1 fill two sides of an A4 sheet.  I need to migrate my mail server to Mint next and I'm not going through that again.

A Lenovo Thinkpad X230 with no keyboard or hard drive arrived today from eBay.

I was allowed to take three laptops from the recycling cage at a corporate I am doing some work for for free. They were three Thinkpads.
The X1 Carbon fired up first time, just had a Bitlocker issue and installing Arch Linux on it got rid of that. Its lovely, I can't believe it was getting thrown away.
The T420 is absolutely fine as well. Could do with another 4Gb of RAM and an SSD to replace the spinning rust but that's it.
The X230i though just beeps and has no display. Maybe no RAM I need to check but its only an i3 anyway. I bought the X230 i5 with no keyboard for less than the cost of some RAM (and it has 8Gb in it). I'll swap the bits between the two and hopefully make one good i5 X230.
The X1 Carbon will be my main personal laptop now I think and the rest will be in my lab.

Bought Monday but arriving today - hopefully soon:


Ultimately all intended to sit behind the TV and act as a media server (hopefully including Netflix (which I've heard can be a bit finnicky to get going on a Pi) as well as Prime, Youtube, etc) and backup server for photos and important files off both of our computers. With any luck even some sort of automatic regular backup rather than just when we remember to. Once I know how big the backup portion is I may get a couple big USB sticks so I can have one in the drawer at work and swap them out as and when is appropriate.

I've been lucky in the past with a PC failure in the middle of my OU degree being the motherboard rather than the harddrives and shouldn't keep pushing my luck  :facepalm:

I don't quite know what I'm doing and I've only ever dabbled with a couple Linux live CDs in the past (Ubuntu vSome# and I can't remember the other) so I expect I'll have some very noobish questions in the coming days.

Apple durability and fixability is 'disappointing'.

Lasted almost a decade; that is not too shabby.
Though it highlights the problem with all-in-one computers. If part of the computer fails, or just becomes obsolete, need to replace the whole thing.
Monitors usually last much longer. Or if you do want to upgrade to something bigger/better, can use the monitor with an old computer, or TV, or games console, or give it away.
A Mac Mini plus a monitor of your choice wouldn't take up much more desk space.

Teltonika TRB140.  (An industrial LTE router with wired Ethernet, that's a bit cheaper and substantially more configurable[1] than the canonical Netgear product.)  This was to replace a buggy USB LTE dongle that was causing all manner of pfSense headaches with its general inability to stay connected and the amount of USB-gymnastics required to make it be a modem rather than a usb-storage device that happened to have a WiFi router built-in.

Having wrapped my head round the necessary incantations required to make it do bridge mode (easy) while still being able to access the admin interface (less intuitive, but I've been through this with various DSL modems over the years and know the score), it seems to be playing nicely.  This should guarantee that our DSL remains rock-solid and help mitigate against any sudden house-moves.

We discussed this but I suppose I just wanted to end DEDD computer problem quickly. I don't think we'll continue to get all in ones. Their heat management seems dismal. D uses MANY peripherals and Mac socket's aren't ergonomically positioned.

I think D's 33 year marriage to Apple might end soon...

Computers and components fail like anything else. Extrapolating singular experiences isn't very useful.

I think a 2012 computer is fairly good going, in 2012 they were probably looking at a three-year intended life (I suspect that's gone up these days).

No idea about heat management, mine doesn't get hot. If there are lots of peripherals, get a powered hub. I just have a single wire out the back to the hub.

Cheap, low spec and impossible to repair without oodles of patience and ingenuity.
All in ones are probably a bit easier than laptops, depending on how many bits are soldered onto the main board/how much glue has been used. No dastard hinges to contend with, as in a laptop!

I really like Dell's business orientated stuff because you can download official guides on dismemberment, should you find yourself in the position of trying to fix one.

A new fancy waterproof Kindle Paperwhite so I don't have to put it in a plastic bag when reading in the bath (an exigency because I used to nick all the bags from the security checkpoint at Heathrow, they were a perfect size and thickness).

I nearly bought a camera for the BHPC (automagic finish line photos, for the capture of), but aborted at the last minute as it appears the software developer is experimenting with adding support for Ethernet (rather than just USB) cameras.  Hurrah.

As a rather sad consolation prize I've bought an Apple Pencil. Never been convinced about styluses but I like to scribble notes in my ladylike handwriting. I have a wipe-clean Rocketbook thing at the moment, which is fine, though wiping it is a minor first world hassle and I get inky fingers. I don't really save the notes in the end, somehow writing them down imprints them on my mind. I also doodle exciting and informative diagrams. And occasionally vampires dining on the throats of those displeasing me. Don't make meetings borings, kids.

My typing has got a lot worse recently, I'm either missing out entire words or doubling up on bits of sentences. This of course could be an undiagnosed brain condition, but I've decided it's down to me using laptop keyboards exclusively for the past couple of years. The low travel silent keyboards on laptops are too quiet, allowing me to get easily distracted by other conversations in the office etc. Previously the click clack of me typing on old school keyboards drowned out all other noise and helped keep me focused on the email being drafted. So I went down the mechanical keyboard rabbit hole, and and now have a Keychron k2, small form factor wireless keyboard with brown switches. The wife complained about the noise about 2 minutes into me setting up the keyboard, and requested that I don't use it at home. The brown switches are supposed to be relatively quiet compared to the blue and green switches that I had been considering.  The rest of the team are going to love me hotdesking in the office tomorrow.

I have a keyboard with brown keys at the office. A few others have also bought the same. I was a bit worried when I first got it (hence the brown keys) but there have been several comments about how nice it is to hear fluent typing on a proper keyboard.

When WFH started I bought one with black keys for home. It's nicer still to type on, but then I don't have a The Wife to complain about the noise.

Strictly speaking, we're not allowed to use anything other than the company keyboards unless we can prove to occupational health that we have a documented need, but it's tolerated as long as we don't bring it to anyone's attention. As my job is typing all day, I'd rather leave than spend 8 hours a day typing on what is basically a sheet of foam with jam on it.

The red silent keys seem to a fair compromise between a nice tactile keyboard and noise. Noise level comparable with a membrane keyboard unless people hammer them home on each key stroke as if using a mechanical typewriter.

The keyboard is probably the only 'expensive' piece of kit in my home office, other than the work lapdog.

Indeed. I have a 2009 vintage monitor which is working perfectly. It was ex-display when bought, & was used with the main household desktop until that was relegated to reserve last year & the monitor went with it. Still used whenever Mrs B & I both want to use a computer.

There's an older monitor tucked away somewhere which was used a lot in the 2000s before becoming the spare, & then intermittently. Now it's the spare spare.

A laptop has to be all in one, but if a computer is going to sit on a desk, I'll go for separates. More comfortable keyboards, too.

I do like an all-in-one computer, it's just less faff and looks neater, there's already enough crap on my desk. That said, if Apple don't release another monster iMac then I might have to take the Mac Mini route (I don't think anything I use a computer for these days justifies a Mac Studio). This one is seven years old (I'm a tad surprised that it won't run Ventura) but still quite capable and the 27-inch 5k retina display lush so I'm not in a huge rush to upgrade. The sparkly new mothership Macbook Pro is quite sweet though, loving the keyboard even more than this Magic one, which I love quite a lot.

My budget doesn't stretch to Mega-Global Fruit Corporation computers, especially if I'm just going to end up running Linux on them, but the appeal of iMacs took a dive for me around whichever model it was that suffered from premature graphics card failure.  I looked up how to repair it, and the procedure for getting at the relevant components involved the sort of equipment normally used while hanging upside-down from a rope above a heavily alarmed display case in a museum.

The laptops are still lovely, thobut.

If your computing needs are modest there are plenty of small fanless machines that can be screwed to a VESA mount or otherwise hidden behind a standard monitor.


(Spare monitors seem to have a habit of breeding.  I currently count four that are old enough to still be square kicking around in here.  A couple of them have whistly power supplies or flickery back-lights and really ought to go in the WEEE pile.)

Which is one of the benefits of the Apple-verse. Of course, if you want to fix them yourself, there's not point in buying a machine that's basically a sealed unit.

"Forgive me Father, for I have sinned"

Just bought (in stages, including some spotting of "Black Friday deals") a complete set of components for a new desktop PC. As this 10 year old one is managing with 4TB of storage which is getting stuffed (I manage 2 photo archives, and photos have typically been 42MP in recent years, now escalated to 50MP, so a fair bit of space is required) I'll have 2 nvme drives, one 2TB for most everyday stuff including the smaller photo archive, and one 4TB one for my main personal photo archive, which insists on being in one volume, for its 30k plus images.  Trying to avoid excessively "gaming" graphics cards, yet having enough grunt for rendering images, and processing photogrammetry is quite a juggle, and I'm very keen on keeping both noise and power consumption to a minimum, so there are some compromises.  I'm still £2k poorer, though!

I get fed up with everything being gaming orientated, I haven't played a game on any computer since I played "elite" on my brother's BBC micro.  Its a tool, I want it to do its job, without flashing multicolour lights and fancy windows in the case.

Ah, I do need to buy a fingerprint reader, as I utterly detest having to "sign in" to an OS on my own PC in my own office in my own locked house whenever I start it.  So far managed to convince this PC to stay sans login, but failed with the laptop when I had to rebuild it, and I gather Windows 11 insists.

Having been previously warned, I was able to set up the BHPC's new (less viscous) jam-filled Windows 11 Babbage engine to not require a login on boot or (and this is the best bit) a Microsoft account.

The whole plan hinged on being able to deny it an internet connection at the crucial moment during the setup process.  This was easily achieved, as the machine itself was selected for that increasingly rare feature - a wired Ethernet port.  But if you have to use WiFi you could maybe apply a firewall rule or turn the access point off or something.
Title: Re: Bought any computing stuff today?
Post by: Wombat on 10 December, 2022, 05:59:01 pm
Aha, The new one will also be ethernet only, so denial of access is probably the favoured answer, but I'm sure I've seen something of what Commutetoofar suggests.  I do have something of an aversion to the Microsoft account.  I definitely subscribe to Kim's opinion that "yer can't beat a bit of wire" for internet connections, and the router is about 1.5 metres away from the PC, anyway. 

Currently playing with today's "toy", a thermal imaging module for the phone.  I sorely miss the thermal imager I always had access to at work, but that cost about £7.5K, and it seems the little module has higher resolution, and cost me £235 on an Amazon "deal". First discovery was exactly where all the central heating pipes are buried in the concrete floors of this place.  Even in 1985, that must have been a pretty stupid idea...
Title: Re: Bought any computing stuff today?
Post by: DaveJ on 11 December, 2022, 10:45:34 pm
The latest version of Windows 11 is more insistent about the Microsoft account, and if you pull the ethernet out, or turn off the Wifi, it says it can't continue until you have an internet connection.

You can get around this by Ctrl and F10 for a command prompt, and then OOBE\BYPASSNRO

But....I've seen a couple of Windows 11 machines with local accounts recently, with Disk Encryption turned on, and buried in the control panel, a message to say "Sign in with a Microsoft account to complete the disk encryption set up".  Quite a lot of potential here for losing the whole contents of the C: drive, because the bit that it hasn't done is to save the encryption key.  These machines were Windows 11 Home, not Pro, and the owners had not intentionally turned on Disk Encryption.  I rebuilt Windows 11 from scratch on one of these machines (disk initialisation and installation from USB), and it after I had done that, the C: drive ended up with disk encryption turned on, and again, without a Microsoft account to save the key into, the possibility of losing the whole contents of the encrypted disk.

I don't like it, I think it should be the owner's choice to have a Microsoft account or not, but I think its too dangerous to have a local account now.  The encryption key needs to be saved somewhere, and there's a bit less chance of losing it if its saved in a the Microsoft account.

Earlier on this year, I saw three Microsoft Surface machines in a fortnight, that all started asking for the encryption key after a Windows update.  None of the data was recoverable, because either there wasn't a Microsoft account to recover the key from, or the the key wasn't in it.  My guess is that Microsoft bundled a BIOS update for the Surfaces into Windows Update, and thats what wiped the key from the machines.  Without the encryption key, the data was toast.

Anyway...bottom line, bite the bullet and accept that Windows 11 needs a Microsoft account and associated logon.

New iPhone and watch. The old ones were running on battery fumes after five-ish years.

Ok, they’re a tad faster and the always-on watch is a boon. Probably the last upgrade ever as I’m now locked out of my bank account as it was tied to the last phone and through some ancient mishap my important details are awry.
