Well sadly I have a Kubernetes cluster I've just stood up, using some ansible that I have spent this afternoon taking pains to finish.

Now what the hell do I do with it?  ???

The battery in my phone no longer lasts a day, but other than that, it's still fine (it was top of the range 3 years ago). Samsung service centre initially said they could change the battery for me, but ultimately couldn't, as mine is a Hong Kong model, and has a different battery SKU number. So after watching a lot of videos in youtube I decided to take the risk and change the battery myself.

Essentially all modern phones are kept water tight by hot melt glue, you have to heat the back of your phone with a hairdryer, and then try get a little sliver open, and then get a paper thin piece of plastic in the crack to slice through the glue, and ball it up, and the glass back should lift off.

Took me a couple of hours, and in the spirit of fix it until it's broken, I cracked the glass back when I was a bit impatient. However the new battery is in, and I've got a few more days of battery testing before the new glass back arrives and I reseal it all.

I am valiantly putting off the installation of my new steering wheel on account of the undignified rolling around on the floor required.  It's cold down there…

I sent my iMac to the guys that provide cover for the office computers when it needed a new HDD.  Cue an email asking if I had ever noticed a crack in the screen.  No, I replied.  Totally honest, never been damaged, sent to them in original apple packaging.

iMac returned one week later with new screen!  I did feel a little sorry for them until I saw the latest invoice for their care package for the offices.

Fettling my oil tank readings into influxdb.
A couple of years ago I set up rtl_433 on a pi to listen to the level sender and log the data.  The readings I have are intermittent and were spread over various places.  Initially they got logged to csv on the pi.  Later I set up influx & told rtl_433 to send the readings there.  That wasn't satisfactory as it gives you no control over the database schema.  So mosquitto and rode-red were recently added to the mix and once I'd figured them out and designed my schema readings started going to a new measurement (equiv of an sql table).  Useful metadata is added and the data goes in as appropriate data types instead of all floats.

Now comes the hard part, getting all the historic data in.  Some was in the old measurement, some was still on the pi in csv form.  I got there eventually but I hit upon a dirty little secret of node-red.  The influx output node doesn't use the time in the mqtt message it receives, the timestamp sent to influx is the node-red inject time.  Yep, node-red corrupts your data.

That, to me as a control system engineer, is effing nasty.  Recording the wrong timestamp on your data ffs!  I'd get fired if I did that at work and rightly so.

There is a solution, don't use the influx inject node, use the influx batch inject node.  That's designed (obviously) for sending multiple data points in one go but it works fine with just one.  Another day of head scratching and I had data flowing via batch inject and the timestamps in influx were correct.  Pity about all the corrupt data....

Luckily I'm a cautious engineer & when I got rtl_433 logging to influx and then later to mqtt I didn't stop the local csv logging :-)  This meant I could identify, delete and re-inject the readings node-red had cocked up.
Next I need to fix the nodes I have recording temperature and humidity data.  I should have correct backups for that too.

/Toddles off to see if I can submit a bug report...

Upgraded barakta's Mac from 832MB of RAM to 896MB, because I could.

Changed the battery on my Toshiba Satellite laptop.

Removed all the screws in the base, which didn't seem to be enough. Quick reference to utube revealed that just two at the back release the complete battery unit, so simples.

Had to reset the time and date on restart, ignored all the other options which I didn't understand anyway.

The new one is white rather than black like the rest of case, very distracting during usage, so stuck some black handlebar tape on it. Battery now lasts about four hours rather than 20 minutes, though I usually keep the mains unit plugged in and exercise the battery once a week.

I passed the screwdrivers.....

I went into the office for the first time in nearly two years yesterday. My bosses' laptop was on his desk, powered on as it has been for the last two years so that he can access it remotely.

Later in the afternoon he unplugged it to go to a meeting and by the time he returned the trackpad had started to bulge. It got worse. Both upper and lower halfs of the bottom were bulging. Screws were failing. Obviously the battery was having a major sulk.

As I'd taken my small screwdrivers with me (Wera, natch) I have them to him and he opened it up to remove the corpulent energy store.
Won't somebody think of the hamsters!

Cleaned fly contents off my screen from where I had rubber-banded a big'un off to infinity.

Drained the coolant out of my dead all-in-one CPU 'water' cooler, I don't think it is supposed to be lumpy.
Rinsed out with distilled water from the dehumidifier until the lumps stopped appearing.
Refilled with heat transfer fluid left over from the solar thermal install on Mrs Tween's barn.

Running at ~50˚C so far.  £63 saved if it holds.
