(3 minute read)Huawei plans to release two new AI chips next year. The company has now shipped more than 1,000 of its AI-computing systems to over 370 customers. China's AI chip market is projected to grow to $67 billion by 2030. Huawei's chip-making technology still trails Nvidia's, but the company is developing workarounds and new designs to squeeze in more computing power while using less advanced equipment.
(3 minute read)Anthropic claims that its Claude chatbot drives more than a quarter of its research and development work. There are over 30,000 agents doing research and engineering work at Anthropic at any one time. Its staffers collaborate with the chatbot for about 90% of their work. The company is trying to create a framework to track agents and monitor the amount of work they do.
(17 minute read)The differences between the versions of the Raptor rocket engine are stark. Many people initially didn't believe SpaceX when the company released a picture of the three generations of the design. The streamlining of the design also brought meaningful gains in performance - the Raptor 3 provides about 35% more thrust than the Raptor 1. This article looks at what specifically SpaceX changed that allowed it to take the Raptor from a tangle of wires and pipes into the svelte, streamlined engine it is today.
(14 minute read)Helix 2.5 is an advanced neural network pretrained on Index, Figure's global-scale dataset of human behavior. It can tidy living rooms, fold towels, and make beds in homes it has never seen. The model is the first evidence that whole-body intelligence can be learned from human experience and transferred to new scenarios. Index is now generating roughly 35 minutes of new human experience every second - if Helix 2.5 is any guide, more data and compute should translate directly into more of the physical world learned before a robot ever enters a new home.
(11 minute read)Researchers chained two critical vulnerabilities to compromise multiple OpenAI employees' ChatGPT accounts in July. The accounts could access internal OpenAI repositories and potentially many other connectors. They used one employee's Codex to open a PR in OpenAI's internal monorepo. This post provides a full timeline of the disclosure process and details about how the vulnerabilities were discovered.
(142 minute read)The release notes on the WebKit features for Safari 27.0 are the longest yet, detailing 83 features, including Safari MCP. Safari MCP makes working with coding agents dramatically easier. It gives users' agent of choice control over the browser window so it can see how code renders. The MCP provides access to the DOM, network requests, screenshots, and console output, allowing agents to do more with less effort from users.
Currying, purity, functors, monads…? If FP terms ever go over your head, TC39 delegate Hemanth HM's popular jargon reference is now an explorable map of concepts showing how they relate, each with a simple definition and JavaScript example.
Master.dev instructors build at Anthropic, OpenAI, Netflix, Google, and Stripe. Learn from them with hundreds of courses, live workshops, and expanded AI learning paths. New members get $100 off a yearly membership.
TypeScript's DOM types only include APIs shipped in multiple browser engines, so things like element-scoped startViewTransition and fetchLater throw up errors. modern-web-types is a drop-in lib.dom replacement that adds missing interfaces/members shipped in any single browser engine.
A significant minor release making view transitions and Fragment Refs stable, adding Trusted Types support, and more. We covered it in more depth in last week's React Status.
A simple async/await example produces different results in JavaScript, Rust, Python and Swift. Test your mental model with a quiz, then learn about the design choices behind the differences.
Shopify is moving away from React Native to native
GitHub's Copilot runtime moved to Rust, ported in pieces behind napi-rs shims while shipping daily. Startup times and memory usage inspired the move, but the gold for porters is in the regressions they hit involving number types, || semantics, and blocking the event loop.
Zoom the chart, change the range, and the whole query reruns from scratch. TimescaleDB extends Postgres so those aggregations return instantly. Continuous aggregates pre-compute rollups so dashboards stay fast at scale. Get $1000 credit to start.
A reasonably significant minor release that brings a few new things to the table:
A Node API/CLI for rendering JSON diagrams to PNG or HTML. Unlike Mermaid or D2, there's no auto-layout engine, so you (or your LLM!) get to control just where things go, while connection routing, icons and styling are handled for you.
A zero-dependency memcached client built on the modern meta protocol, pipelining over a single connection. Claims to be "roughly 3x" the speed of alternatives.
A wonderful tour of the non-standard CSS quirks developers used to make browsers behave, especially Internet Explorer. Covers the 'star hack', CSS expressions (JavaScript in your CSS!), IE's DirectX filters, the famous box model hack, and more.
✅ — We've shared this before, but it's kept improving and now has almost 400 frontend quality rules covering accessibility, performance, security, SEO, and more. You can also now connect it to Claude, Cursor, and other AI tools over MCP so they review against the same standards.
When text is just one line, an accompanying icon is nicely vertically centered, but when the text has multiple lines, the icon is still 'centered' but can look oddly misplaced… Ahmad explores a fix using CSS's lh unit.
With JPEG XL decoding making its way into Chrome and Firefox, an AV1 encoder developer who once backed the format argues it offers little advantage over AVIF for the web.
Real files came out up to 83% bigger than predicted. Read how a few browser metrics surfaced it.
A Remix team member picks at the just-let-AI-use-React trope. If frameworks don't matter, why use React? Skip one and agents improvise their own makeshift 'frameworks', so Brooks wants new, better ones with solid abstractions and constraints.
Lovable spins up a million Vite dev servers a day, so one of its engineers built OJ, a Rust dev server that reads your existing vite.config.ts and runs Vite plugins, but focused on low memory use and cold start times. It's open source but experimental.
React 19.2's <Activity> can render a hidden tree without mounting its Effects, which caused a leak in a legacy hook that subscribed during render. A practical rundown of what to audit before adopting it.
A new ESLint/Oxlint plugin that lets you declare which Tailwind classes each component accepts, with errors that tell agents which tokens or variants to use instead.
Components for the Konva 2D canvas scene graph library you might use to build whiteboards, diagram/design editors, etc. Now requires React 19.3. Repo.
Live Workshop Series: Debugging AI Agents
On October 7, Serge from Sentry instruments three agents with : a chatbot in an e-commerce store, a custom Slack agent, and a GitHub Action that reviews PRs. You'll see bad tool calls, unexpected output, and token spend per run.
