What matters today: A Guardian investigation found that the UK government's touted 20B pound "Stargate" data center at Cobalt, part of a jointly announced 30B pound AI investment with OpenAI and Nscale in 2025, looks like it was more hype than plan: neither company ever visited the site or filed planning applications. Separately, Anthropic's new Claude Fable model had a quiet coming-out day, turning up independently in a Gaussian-splat research project, a full port of Command & Conquer: Generals to Apple platforms, and a rewrite of Simon Willison's sqlite-utils, a first sign the model is already doing real, unsupervised work in the wild.
AI / LLMs
- Anthropic's Claude Fable model surfaced in three independent builds today: a novel 4D Gaussian splat format (title only, page did not load), a full port of Command & Conquer: Generals to macOS, iPhone, and iPad (title only, page did not load), and sqlite-utils 4.0rc2, which Simon Willison says was mostly written by Fable for about $149.25: three hobbyist-scale projects, but a real signal the model is already shipping unsupervised work.
- GitHub Copilot CLI now lets teams define custom AI agents in Markdown files, turning one-off terminal prompts into repeatable, team-shareable workflows for security reviews, releases, and more.
- A GitHub issue argues GPT-5.5 Codex's reasoning tokens are clustering in a way that degrades output quality (title only, page did not load), drawing heavy debate on Hacker News.
- Armin Ronacher's "Better Models: Worse Tools" (title only, page did not load) drew enough interest to surface on both Hacker News and Simon Willison's blog today.
Devtools & Infra
- Cheyenne, Wyoming suspended a Meta contractor's data center water discharges (title only, page did not load) after they contaminated the city's water reuse system.

Startups & Industry
- AWS is putting Mechanical Turk into maintenance mode and closing it to new customers, signaling the crowdsourcing platform's eventual retirement.
- Neither OpenAI nor Nscale ever visited the Cobalt site or filed planning forms for the 20B pound UK "Stargate" data center ministers touted in 2025, a Guardian source says, calling the plan more PR than substance.
- The EU's automated biometric entry/exit border system is rolling out roughly, with airport operators warning of severe delays ahead of the summer travel season.
- Indonesia's under-16 social media restrictions are being enforced only patchily, with platforms largely ignoring the rules and minors still getting through.
- Some high-income families are turning to AI-powered private schools and tutors like Alpha School to tailor curricula and teach life skills.
- An Irish hotel canceled a "secretive" conference tied to a Peter Thiel group (title only, page did not load) after public pressure.
Research
- The European Southern Observatory warns satellites and space mirrors are pushing past sustainable limits for a dark night sky (title only, page did not load), threatening ground-based astronomy.
- Texas A&M researchers report reversing brain aging in animal trials with a nasal spray (title only, page did not load).
Elsewhere
- NASA launched an emergency mission using Katalyst Space Technologies' Link spacecraft to boost the aging Swift Observatory's orbit before it burns up, after solar storms pushed its altitude down to 224 miles.
- Finland switched off its last analogue landline phones after 150 years of service (title only, page did not load).
- Ars Technica reviews Supergirl: a solid but not great DCU entry, undone commercially by troll attacks, mixed reviews, and superhero fatigue rather than the film itself.
Hacker News
Zig's compiler team stripped all package management functionality out of the compiler and pushed it into the build system (161 points, 33 comments), a structural change worth a look for anyone tracking the language. On the AI tooling side, a GitHub issue arguing that GPT-5.5 Codex's reasoning tokens are clustering into degraded output drew heavy debate (194 points, 63 comments, covered above), while Armin Ronacher's essay on stronger models making tools worse pulled a smaller but engaged crowd (127 points, 39 comments, covered above). Two AI-assisted builds also stood out: a novel 4D Gaussian splat format (133 points, 51 comments, covered above) and a from-scratch Command & Conquer: Generals port to macOS and iOS (426 points, 164 comments, covered above).
Elsewhere, an investigation into a leak exposing YouTube creators' private videos led engagement for the day (531 points, 301 comments, covered above), followed by a Meta contractor's data center water discharges getting suspended in Cheyenne after contaminating the city's reuse water supply (220 points, 77 comments, covered above), and a Wicklow hotel canceling a secretive Peter Thiel linked conference under public pressure (114 points, 43 comments, covered above).
On the science side, Texas A&M researchers reported reversing brain aging with a nasal spray in animal trials (184 points, 71 comments, covered above), and an ESO statement warned that satellites and space mirrors are pushing past sustainable limits for the night sky, threatening ground-based astronomy (117 points, 204 comments, covered above).
Smaller threads rounded out the page: a review of the Common Lisp Cookbook against LispWorks, a proposed $200k bounty for scanning all books at Google Books scale (or similar), Finland switching off its last analogue landline phones after 150 years of service, and grumbling over Verizon's plan to break Gizmo watches.
Threads
- Claude Fable's coming-out day (a splat-format experiment, a full game port, a rewritten CLI tool) lands alongside GitHub Copilot's new markdown-defined agents and a GPT-5.5 Codex bug report: AI coding tools are visibly moving from novelty to daily, occasionally messy, use.
- Government tech mandates are landing rough: the EU's biometric border system and Indonesia's under-16 social media rules are both live regulations that, in practice, aren't working as designed.
- AI infrastructure promises are getting checked against reality: the Guardian's finding that the Stargate Cobalt site was more PR than substance, and Meta's suspended data center water discharges, both puncture the clean narrative around AI's physical buildout.
