You think rewriting Bun in Rust with agents is fun? How about rewriting Git into a memory-safe Rust library? A few weeks and 45B tokens in, the new Grit project is passing 99.3% of the entire 42k test Git testing suite.

One of my personal favorite features announced at WWDC will I suspect be a sleeper hit: container machines, allowing your Mac to run a lightweight, persistent Linux environment with your home directory and repos automatically mounted: github.com/apple/container/b…

PostgreSQL 19 Beta 1 adds ON CONFLICT DO SELECT. Insert a row. If it already exists, return it. Atomic get-or-create, finally. 👇 #PostgreSQL #SQL

Ehh, it tends to shine only if your app is React Native. All the most interesting functionality is from the Expo plugin (like inspection and running simulator side-by-side), and less from the "Build iOS apps" one though that comes with nice setup for skills/CLIs

Tell me you have a foldable coming without telling me you have a foldable coming

Codex is so bad today I need to setup my workflow on Claude too so I can switch easily I am at a point where I wasting more time on iterations on design and copy vs just using Claude instead

you used to spend a day messing with your neovim config, feel self conscious, then get back to work now people are spending weeks on some hyper customized coding agent workflow that definitely is worse than vanilla but they can talk about it like they're ahead of the game

people using herdr: - developers who still choose their own tools - people who like simple software - people who don’t want another app - people who just want to ssh into a vps - terminal enjoyers - tmux users - people who want tmux energy without tmux homework

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

Today, we’re proud to introduce @routinehq 1.0 🎉. What started as a personal productivity tool combining tasks, calendars & notes has evolved into something much bigger: a new productivity operating system for individuals and teams.

Compose Hot..Swan is finally here! 🦢 HotSwan allows you to do Compose Hot Reload in real Android devices, instant UI updates on your running Android app, with state preserved. No rebuilds, no relaunching, no navigating back to the same screen again. hotswan.dev/

five words. 20 years. unfinished.

🛠️ Swift Package Manager support is now available in Kotlin Multiplatform. Try importing iOS dependencies from Swift packages or migrating from CocoaPods. See how to try out this experimental feature ➡️ kotl.in/kmp-swiftpm-import Share your feedback ⬇️🧵

Node.js is moving to one major release per year starting with Node 27! 🚀 ✅ Simpler: Every release becomes LTS. ✅ Predictable: Version numbers now align with the year. ✅ New: A 6-month Alpha channel for early testing. Read why we’re evolving: bit.ly/4rnosLg

You can now run a virtual iPhone with iOS 26.1 Yes. A real version of iOS running inside a virtual machine on Apple Silicon Macs. Not a simulator. Not a fake UI. An actual iPhone environment that boots, loads iOS 26.1, and works like a device. What this means: • iOS 26.1 boots virtually • It behaves like a real iPhone • Graphics acceleration works • Researchers can test without a physical device We just moved from “Apple probably has this internally” to “anyone can build it.”

Finally got this virtual iPhone running iOS 26.1 up and running on macOS. It's jailbroken and going to help with security research a ton. Big thank you to @wh1te4ever for this. This is not for the average user and is complicated to set up. Highly recommend Codex and/or Claude to assist. For those interested, the project is here: github.com/wh1te4ever/super-… And the writeup is here: github.com/wh1te4ever/super-…

🗞️A fully working iOS 26 virtual iPhone now runs on Apple Silicon using PCC firmware — with public setup instructions. This could be a new path for security researchers without depending on Corellium🔥 onejailbreak.com/blog/ios-26…

New art project. Train and inference GPT in 243 lines of pure, dependency-free Python. This is the *full* algorithmic content of what is needed. Everything else is just for efficiency. I cannot simplify this any further. gist.github.com/karpathy/862…

It's very exciting to see @tuistdev's binary cache support for @gradle projects taking shape, and our cache infrastructure getting better every day. We are onto something, building infrastructure for productive developers and agents.

Introducing Claude Opus 4.6. Our smartest model got an upgrade. Opus 4.6 plans more carefully, sustains agentic tasks for longer, operates reliably in massive codebases, and catches its own mistakes. It’s also our first Opus-class model with 1M token context in beta.
