Great investigation work from a horribly under resourced Environment Agency. A record fine of £8M against South West Water. www.bbc.co.uk/news/article...

South West Water fined almost £8m for sewage spills

The Facial Expressions of Tethys by artist Julius von Bismarck. A suspended high-sea buoy that moves in real time. Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

More fiddling with my #watercolor experiments. Added where the colours sit on the gamut solid, and what they are. Ran it through a shader to make it look more like watercolour itself, and put it on a white background. All to avoid working on the app’s marketing.

I wanted to visualise the colours that commonly available #watercolour palettes are able to reach (part of a feature I'm working on for my app Undertint). For fun, I've made a tool to compare them side-by-side. I think they're rather lovely in their own right. justin.stach.uk/palette-spac...
The image shows a 3d solid representing the colours that the Holbein 24 colour Artist's Watercolours Set can reach. It is irregular and rainbow-coloured.

another big one for me is how extreme wealth inequality less a moral issue and more a security risk so much money that you're insulated from every conceivable fuckup demonstrably makes you stupid like the power to drag the entire world off a cliff with you and be the only one with a parachute

Solid and thoughtful. And I couldn’t agree more with, ‘Any platform that uses an algorithm more complex than ‘people you follow in chronological order’ to be treated as a publisher, and held to account for content’.

Interesting that Starmer, like Corbyn seems to elicit the same visceral but never explicable reaction from normal folks. Makes me wonder just what is it about Labour leaders that prevents them clicking with the general public.

My latest project, “Tatebanko” (Mac, iPad, iPhone) to create interactive paper dioramas. Shown is a Hokusai tatebanko from @mfaboston.bsky.social Author shapes and folds, then build! Trace-to-cut, pinch-to-fold, and drag-to-position in an adjustable 3D scene. Sugoi!

Back Rooms is very good, but even better was the two incredibly freaked out people frozen in the cinema’s dark exit corridor because they were trying to push the door open from the hinge side.

I agree. He's made silly mistakes but the actual data proves that the economy is improving (despite a world in turmoil), immigration is down (despite what reform would like you to believe) and we're building closer ties to the EU. Not extreme enough for the left or the right though.

You always get a lot of angry replies here if you complain about the Greens blocking solar farms or power grid upgrades. Maybe they should stop instigating pile-ons and start instigating pylons.
