An example of a hyper-specific niche in a once widely popular platform: Loop cassettes

There are all kinds of convoluted internal pathways, but they do the same thing: Add length to seamlessly continuous playback

The UK is currently cooking on about 12.5GW of wind energy (about 37% of our load) - I think that's a record. It was a bit lower over night, but still electricity prices went very negative in the early hours. Although they were still running some gas (about 2.5GW) and a touch of coal (about 0.7GW - I guess so they didn't have to let it cool down)

This thrush provides a nice christmasy picture, sitting on our rowan, in front of our holly. Curiously it picked holly berries from the ground but not from the tree.

I'm confused if anything could have stopped Friday's attack in London; keeping him in prison for another 8 years might have only delayed it. He was apparently such a model prisoner he was invited to the conference. You can imagine the services monitoring him thinking that a conference on prisoner rehabilitation was as safe a place as any.

Looking at ~6 years energy usage; my electric usage is ~10% down, and my gas ~15% up. Hmm. The gas is very variable though; I guess based on weather and things like the mood the boiler is in and whether people decide they want a shower every day.

Today has mostly been toast, crumpets and paper work. Hmm.

A 1970's tektronics spectrum analyser my dad has open on his bench; the design priority was obviously for it to be shiny. There's some crazy mechanics as well - knobs on the front that go via bevelled gears to move a lever that flicks a normal toggle switch somewhere inside.

I'd hoped the threadripper 2950x's would have dropped after the 3xxx were released this week - but nada; 2950x's seem to be rare now; and their bigger cousins, 2970/2990 have only dropped a few %.

Thanksgiving: how many others in non-us countries have had to correct others in other non-us countries who were surprised you didn't do thanksgiving. People seem to think the UK would.

Hmm another couple of short powrcuts this evening - I guess the last was a few months ago; but it's not something we have here normally; I guess it'll be like this until a cable really goes BOOM and they go 'ah. That'll be where the fault is....'

Fun bug of the week; something trying to allocate 2^49 bytes of ran (64-12 (4k chunk)- 3 (8 bits/byte)

A predator of some type has made it's home on a near by field; not sure what it is - but it's got a great fan tail when it's hovering looking for lunch.
This is as close as I've got it so far.

End of a holiday; done some paperwork (good), made small amount of useful progress on toy project 1 (Good, but wanted to finish it), started another toy project and got quite far (well OK, but as long as it doesn't end up as 1); got awful cold and have almost got over it (hmmm).

I don't see how anyone can promise a zero carbon economy on a day like this; a moderately cold winter day with moderate wind and we're burning away 25GW of gas, 2.6GW of biomass and 3GW of coal; we can get rid of that coal - but no one has any idea what to replace that gas with.

Sigh; tripped over kernel's printf now hashing all %p pointers - confused the hell out of me; even a NULL pointer comes out as some magic potentially legal looking value that confuses the hell out of you. I mean a NULL should look NULL.
