Part of it is the prevalence of "pop and bang" maps, modified ECU configuration which changes timing and allows unburnt fuel to enter the hot exhaust and explode. There is a purpos…

I wrote a PostgreSQL extension years ago that visualises pages (as text): https://github.com/hollobon/pagevis

There have been negative electricity (spot) prices already - https://www.montelnews.com/en/story/sweden-finland-see-negat... .

Sounds very familiar - they probably knew each other.

Ha. My father worked for Norsk Data in the UK during the late 1980s and early 1990s after they bought Wordplex. They had incredible offices at a stately home near Newbury.

Under £500m. Still a huge amount but considerably less than £9b. https://www.bbc.co.uk/news/health-26954482

I've used it for about that long, with no real problems at all. We have probably a hundred or so migrations, and have added support for various things not supported out of the box …

This looks interesting. If you're using SQLAlchemy, Alembic is a good migration management / generation / application tool: http://alembic.zzzcomputing.com/en/latest/ , and works w…

Only seen it done with ones removed from old keyboards. On at least some (including the IBM SpaceSaver IIs that I have), it's on a separate little board. I believe the outputs are …

I guess with practise it may well have improved. I just didn't find it comfortable enough to persevere.

I've got one of the thumb keys on the left of the Kinesis mapped to shift; never quite got used to it though and I'm always mistyping when holding it.

I've been meaning to hack a trackpoint into my Kinesis. It's been done before, mounted where you can control with the thumb so you don't need to move your hand at all.

The trouble is tuning it so that you don't need to actively hold your foot to prevent it actuating, and also having enough feedback on actuation. I felt that some kind of wireless,…

I converted a set of pedals for a dictation machine to work with my Kinesis keyboard. It wasn't as useful as I expected. Having to keep my foot in the same place all the time becam…

IIRC the other shot is somewhere south of the river. I worked it out at the time. I was near Tower Bridge on the north side.

Oh yeah, I don't deny it isn't insanely improbable. Still, finding same strike in a newspaper, shot from a very similar angle, was quite surprising.

I had the same thing happen with one of my photos of lightning in London. I actually thought my shot had been ripped off at first glance, then realised it was from a different angl…

I found this post about latency of input devices very interesting: https://danluu.com/keyboard-latency/

Love this sort of thing. I did a Tetris game for a led-matrix clock I got from Banggood: https://github.com/hollobon/jy-mcu-3208-tetris

Porting an ancient 6502 Forth to Z80. Nobody will ever use it and there are already loads of Z80 Forths around, but it's fun and forces me to learn exactly how a language that's al…

Agreed, and it's become common on many more cars than supercars to add valves to make exhausts noisier. I suspect these valves are not triggered in regulatory exhaust noise tests. …

We use ZFS (on Linux) clones to instantly fork a read-only replica of our production database, to create r/w copies. We also currently have these upgraded in-place to 9.6 (we're st…

This is cool. Always worth spending some time setting up psql. In my psqlrc I also have a bunch of "macros" (unfortunately no parameters in psql) for common stuff like transaction …
