  1. Quoting John Gruber

    Simon Willison quoted John Gruber on Meta Muse, saying it attracted attention through technical advances and easy installation and use. Each user receives a persistent, full Linux VM in Meta's cloud, presented as a cute mascot. Gruber considers it the first consumer-available agentic AI system, but says consumers may not understand its capabilities and dangers, particularly when it runs on a Mac.

  2. NarrateAI: production-ready LLM quality assurance on Amazon Bedrock

    NarrateAI uses five techniques on Amazon Bedrock to achieve around 99% numerical accuracy with real-time streaming responses for over 4,000 AWS executives: adaptive pipeline orchestration, cross-account multi-model failover, real-time streaming evaluation, a composite evaluation framework and data-accuracy validation. Around 90% of queries take a single-pass fast path; only about 10% use parallel batch processing.

  1. Trump admin using AI to deny medical care for seniors in disastrous experiment

    The Trump administration launched WISeR in January, a pilot using AI to decide authorisation for some Medicare services for elderly patients, which previously required no advance approval from doctors. Reports described technical failures, lengthy approval and treatment delays, confusing denials and patients waiting in pain. Federal documents obtained and published by the Electronic Frontier Foundation in litigation earlier this month, including provider feedback, largely corroborated those reports.

  2. The Pentagon wants $30 million to build an AI-powered lie detector

    The US Department of Defense requested $30.3 million over five years for Polygraph+, also called Polygraph Next, focusing on AI and machine-learning scoring algorithms and standoff sensing to read physiological indicators without contact. The Defense Counterintelligence and Security Agency (DCSA) is responsible for the project, intended for employee screening and insider-threat detection. Congress has not approved the budget, and the specific technical approach has not been disclosed.

  3. Northern Gannet, Great Blue Heron, California Brown Pelican

    Northern Gannet, Great Blue Heron and California Brown Pelican were observed at Monterey Bay National Marine Sanctuary, California, from 7:07 to 7:27 pm. A new 200–800 mm Canon EF lens captured the best Morris photos yet; they like staying beneath that sign in the harbour.

  4. Note on 24th September 2026

    In notes on 24 September 2026, Simon Willison said that the more time he spent working with coding agents, the more convinced he became that they made software engineering harder. He believes they can produce astonishing results, but realising their full potential requires exceptional discipline and knowledge.

  5. When chat is the wrong UI

    The GitHub Copilot app introduced canvas, full-stack mini-apps running inside the app without browser chrome. They communicate bidirectionally with Copilot agents and can call third-party APIs or execute code locally.

  6. New Jersey fines data center $1.1M after drone pics expose 62 gas generators

    New Jersey fined DataOne's Vineland data centre $1.1 million this week for secretly installing and operating unpermitted gas generators in breach of its Air Pollution Control Act. The Guardian and Floodlight News discovered them with a thermal-imaging drone in August: 45 of 62 generators were running. None had the permits required for capacity of 37 kilowatts or more, while actual operating capacity reached 1,982 kilowatts.

  7. Google's first Suncatcher orbital data center test launches October 1

    Google's Project Suncatcher will launch its first test satellite, MVP, on 1 October to validate an orbital AI data-centre concept. Roughly refrigerator-sized, it carries four Google-designed TPU accelerators and about one kilowatt of solar power. Google integrated the chips into a satellite already built by imaging company Planet Labs to accelerate progress; the original plan was to launch two custom satellites in 2027.

  1. Trump’s China rivalry and “AI race” delusion may endanger US, experts say

    The US and China began AI safety talks this week. Treasury Secretary Bessent says they discussed a new notification mechanism that, with Chinese participation, could alert either side when its AI systems pose threats or behave unpredictably. Reports also note tighter Trump administration export controls, congressional bills further restricting chips and hardware, and US Justice Department accusations two weeks ago that six major Chinese AI firms stole frontier lab technology, strongly denied by China. Experts say Trump's China competition and AI race narrative could put the US itself at risk.

  2. XPRIZE Wildfire winners spotted fires within 10 min—but couldn’t stop them

    Results of the $11 million XPRIZE Wildfire competition left both grand prizes unawarded. The space detection track required identifying fires across a large Australian area within 10 minutes; SIRIUS Wildfire Alliance won a $500,000 first-place award. In the autonomous response track, tested across 386 square miles in Alaska, all three finalists detected high-risk fires within 10 minutes, but none completely extinguished them.

  3. YouTube promises custom feeds and a lot more AI later this year

    YouTube announced Custom Feeds at its annual Made on YouTube event, generating personalised content tabs from descriptions and saving multiple feeds. It will launch soon for US web, mobile and TV users. GIF comments and group chats in YouTube messaging are also coming this year, initially limited to the US, UK, Singapore, Brazil and some European countries.

  4. Rendering huge pull requests in the GitHub Copilot app

    GitHub rebuilt its Copilot app's pull request view to handle rendering pressure from huge diffs and comments, testing an open-source PR with 2,200 files, over 1 million changed lines and more than 400 inline comments. It separates document height into deterministic code geometry and dynamic block geometry: code line heights are computed precisely in advance, while comments and other dynamic blocks use bounded heights and deferred measurements, with corrections anchored to the user's current position.
