Happy beached whale dynamite day for all who celebrate

900 stars 7 days after release – I think it's safe to say we had a very successful launch with @zensical.org. We're super happy and the feedback is overwhelmingly positive. Thank you all for supporting our work ❤️

Mozilla Festival took place in Barcelona, and I really loved it. It’s a conference about how we can all fix the Internet with Wikipedia, Tor, EFF, lawyers, and activists. Compared to boring tech conferences, it was a real breath of fresh air. Highly recommend.

The Chinese Kimi K2 thinking model beats GPT and Claude on some benchmarks. This analysis from @natolambert.bsky.social is a good overview iew of what is going on www.interconnects.ai/p/kimi-k2-th...

ATProto devs PLEASE COPY THIS 🙇‍♀️ 🙏❣️❣️

Breakthrough 🤯 You're seeing - ALL my @leaflet.pub articles 📄 - from ALL my Leaflet publications 📚 on my 🚧 new site (in dev) 🙀 that's - version-controlled w/ @tangled.org 😳 - (soon) hosted w/ @nekomimi.pet's wisp.place 😱 EVERY PART is stored in my #PDS 🫠 #ATproto is the future!!! WTF 💙

Async QUIC and HTTP/3 made easy: tokio-quiche is now open-source blog.cloudflare.com/async-quic-a...

A free, non-VC funded lifestyle business idea: AI training / workshops for devs Massive demand from more traditional companies that have budget for this and are seeing devs not really picking up these tools. They want to invest Doesn’t exist as far as they are aware

I've been getting a lot of value using coding agents for code research tasks recently - I have a dedicated simonw/research GitHub repo and I frequently have them run detailed experiments and write up the results. Here's how I'm doing that + some examples: simonwillison.net/2025/Nov/6/a...

Every single woman you know has had this happen to her. Even the goddamn president of Mexico.

I really like Material for MkDocs, but this is some excellent news ♥️

So many amazing Gleam talks at @codebeam.bsky.social Europe! Yoshie's talk on safely and cautious adopting Gleam in existing businesses was absolutely brilliant. Really looking forward to the video being published

We're making the plc.directory more transparent and accessible! Its happening! 💪 There are already 5 public instances of plcbundle running, providing a complete and *verifiable* copy of the directory to anyone. plcbundle-watch.pages.dev

Exciting news! Today, we announced the Rust Foundation Maintainers Fund: an initiative to provide consistent, transparent, long-term support for the developers who make Rust possible. Supporting maintainers = supporting Rust’s future. Learn more: rustfoundation.org/media/announ...

A lot of specialized open source models for engineering tools would be nice. Ideally, they could run locally.

I wrote a bit about my sidequest at Earendil: Building Absurd which implements durable execution (𝚞𝚜𝚎 𝚠𝚘𝚛𝚔𝚏𝚕𝚘𝚠, Temporal, Inngest, etc.) on just Postgres. How it works and why I like it. lucumr.pocoo.org/2025/11/3/ab...

I'm surprised by is how many people that I'm interviewing mentioning that they don't use coding agents due to cost for their side projects. There are in fact free agents. Amp Code has a free tier and at the moment you can use Grok fast, still for free on OpenCode and others.

I don't celebrate the holidays by spending money. I celebrate the holidays by spending time. Community over consumerism.

The number of numbers in red circles I have throughout all software I use at work is maddening. Zoom is a big offender here trying to get me to read chats from all meetings.

My observation is that if a masc says something the listener doesn't believe, the response is always to give the benefit of the doubt & question gently Whereas if it's a femme it's a presumption that she's incorrect and an aggressive and hostile questioning You see it in PRs and doc reviews too

Every day it feels more and more like a zombie apocalypse over on LinkedIn, in which you start a conversation with someone who you hope is an ordinary person and then a couple of turns in discover that they have surrendered their brains to the "AI" mass delusion.

I wrote up some notes on two new papers on prompt injection: Agents Rule of Two (from Meta AI) and The Attacker Moves Second (from Anthropic + OpenAI = DeepMind + others) simonwillison.net/2025/Nov/2/n...

Rust 1.91.0 has been released! 🌈 🦀 This version brings you tier 1 support for aarch64-pc-windows-msvc, warnings for dangling pointers to locals, new methods on AtomicPtr, array::repeat, BTreeMap::extract_if, const TypeId::of, and more! Check out the announcement: blog.rust-lang.org/2025/10/30/R...

Ahoy! 🏴‍☠️ Claude got network access. When enabled, it can also communicate with Anthropic APIs! Twist: Attacker sets their own API key in prompt injection payload to upload user's data to their account 🔥 embracethered.com/blog/posts/2...

We made MLS more decentralized! We are excited to share DMLS that brings fork resilience to the MLS protocol, solving a key challenge in distributed systems while maintaining Forward Secrecy. This work was made possible by @equalitie.bsky.social, who funded it as part of the Breakout program.

Celebrate small wins as well 🎉

This is some good damn leadership. Respect to the PSF for sticking to their values.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms). It’s also concerning. 1/

I am a month late to the party, but the Chrome DevTools MCP is pretty sweet. developer.chrome.com/blog/chrome-...

First time trying Axum and it's a sweet web framework github.com/tokio-rs/axum #Rust #W#Rust #WebDeve#IndieDev

It's neat how if you ask Claude Code questions about itself it can answer them, because it knows how to fetch a Markdown index of its own online documentation and then navigate to the right place I wish more LLM tools would implement the same pattern! simonwillison.net/2025/Oct/24/...

💯 uv made Python a valid option beyond simple scripts to me.

Exactly, local-first is not an alias for offline. It is the benefit of a local app with local data and the benefit of a typical SaaS product at the time. This includes team collaboration ♥️

See you in London, Nov 11th. Room for a couple of lightning talks if you have something to share.

🫠 automerge.org The new Automerge website is live!! The biggest (smallest) surprise? How fun it was to build the demo! Automerge is so robust, it withstood all our weird ideas — like using physics-driven particles to literally push changes between docs — and it just worked. Perfectly. Every time.
