Nope. Stopped using it and locked my accounts quite a long time ago and finally deleted them earlier this year. I don’t want anything to do with anything supporting Musk, and he’s distorted twitter to meet his desires.

Hello! Yes, I have a separate account for creative/performance projects, more personal things and general waffling, to keep this one clear for sust build stuff.

If you're not familiar with @thedailytism.com , I HIGHLY recommend becoming familiar with them. They're brilliant. Searingly funny, on a daily basis, making the world better one highly-entertaining satirical article at a time. Having now worked with them, I can confirm they're also just top humans.

I find internal overheating hardest to cope with when there's no air movement. On a breezy day I prefer to keep windows a little open as the cross ventilation makes it feel cooler. Today is still and feels airless, so I'm shifting to closing the windows and breaking out the fan.

It also features an excellent introduction to heat pumps from Paul Rychnovsky. He managed to explain the functioning of them so clearly that I actually understood it properly at last :-D

Excellent investigatory air / smoke test and thermal image survey by @thermalimageguy.bsky.social . Very thorough, very clear, and incredibly helpful!
