So pleased that the team I work with at Southwark Council has been nominated for the Digital Leaders – AI Impact Awards 2026. Our project uses AI to convert PDFs into accessible HTML, making council information easier to access. awards.digileaders.com/AIImpactAwards…

Asking two agents in different harnesses to debug your code (from andirockk on IG)

Obviously AI, but I wish it was real, imagine how much better international relations could be and what great trade deals would be negotiated!

Happy Easter!

I know you're all getting mighty tired of seeing typography on your timeline today! But here's a pretext.js demo that (hopefully) isn't a crime against justification and indentation.

finally the web has become interesting again

My dear front-end developers (and anyone who’s interested in the future of interfaces): I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept): Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

My favourite live show of all time - was always such a great way to start the day!

‘Dune is about religious fundamentalism and the danger of charismatic lead-“ Actually it’s about the importance supply chain diversification

It will soon be possible to build Platonic Park…

So cool. I imagine this can be built on to create a free home security system.

The Great Orme is a limestone headland on the North Wales coast. It has a herd of approximately 200 feral Kashmir goats. They were given to Queen Victoria in 1837 by the Shah of Persia. She kept them at Windsor. At some point in the Victorian era they were moved to the Great Orme. They have lived there, unmanaged, entirely feral, for approximately 180 years. They are technically still the property of the Crown. The Crown does not appear to be particularly exercising this ownership. The goats, for their part, have no opinion on the constitutional question. They have opinions on gorse, on limestone scrub, on the timing of the tourist season, and on the structural integrity of garden fences in Llandudno. Because several times a year: usually when the weather on the headland becomes unacceptable even by Kashmir goat standards, they come down. Into the town. They eat the hedges. They occupy the gardens. They stand in the road. They have been photographed in chip shops, bus shelters, and outside estate agents with the calm assurance of animals that know they were here before the terrace housing and will probably be here after it. Llandudno has 20,000 residents and 200 goats and it is not always clear who is more inconvenienced by the arrangement. The goats have never once asked permission. They were here first. Technically the Queen gave them the place.

@BreatheLesss Trust the art history!

One time I mentioned this theory to an art history major. She looked me dead in the eyes and said:

@InputEndorsers @planetmaaz The Builder Bear strategy?!

@planetmaaz I'd love a deeper comparison among 20+ currencies (strong and weak) with/without treasuries, which ones do/don't have max cap (important too!), where does the funding come from, who allocates it in which ecosystem, UTXO/account-based etc... A deeper insight w/ multiple factors

Advocating for a Cardano NCL higher than 350m Ethereum spent aggressively through a 94% crash in '18-'19 → funded Uniswap, Aave, Compound → DeFi summer '20-'21 Solana expanded grants post-FTX '22-'23→ ecosystem resurgence 24'-'25 Build through the bear. Win the bull. few.
