Heads-up that I've changed my bluesky handle to @jbsustbuild.bsky.social from @thewoodlouse.bsky.social to avoid confusion with my creative alter ego (@the-woodlouse.bsky.social). It's always possible that this will make things worse, but at least I've tried!
I’ve very much neglected this account. General life pondering and rubbish-talking now happen on my other account. Not sure how many of the Passivhaus/low-carbon/low-impact construction people are still active on here, but just in case: Hello! [waves].

It's national Get That Slightly Squeaky Fan Out of the Loft Day for those of use that don't live in a house where overheating risk was properly considered. It's already 24° in my office but the air movement from the fan helps it feel more comfortable, squeak not withstanding.

This episode is amazing. If you want to know what it’s actually like being autistic (as opposed to the stereotypes) it’s a must-listen. I’m autistic & this episode is just about the most validating thing I’ve listened too, ever.
Also, effing funny. Also the best (wholly justified) righteous rants.

I wish the UK gov would focus on tangible improvement of public services and people's lives instead of blaming immigrants.

Migrants have not done “incalculable damage to our society”. People scapegoating, othering, and encouraging hatred of migrants (and others) *have* done that.

1. The Supreme Court ruling is not "the law", nor has it changed existing legislation.
2. The EHRC's interim update is also not "the law". It isn't even "guidance".
3. The upcoming EHRC guidance, likewise, is not "the law". Again, the legislation hasn't changed.

Love this chart
This chart is internet-famous since Steve Jobs allegedly looooooved it. It shows how much energy (measured in calories) is needed to move objects by weight. A human on a bicycle is outrageously energy efficient. Cycling is the king of transportation!

2. Coffee break in the sun outside my back door, staring at the sky
3. See my first swift of the year gliding about above

This analogy definitely works if your kid has a disability or health condition that means they can’t get a Saturday job and if they don’t get a Saturday job, you let your kid starve to death
Jeez. Treasury Secretary Darren Jones compares Labour's welfare cuts to cutting his kids' pocket money when explaining the Government's impact assessment
"I'm going to cut your pocket money by £10 a week but you have to go and get a Saturday job"

Watching a very depressing but incredibly useful smoke test video of a post retrofit house. Lots of leakage at floor to wall junction (suspect leakage through floor, and wall not properly sealed to floor), and a fair bit around windows (both through window seals, and join of window to building).
