Sprites.dev by @fly.io is a very cool new thing: it solves two of my pet problems at once, developer sandbox environments for coding agents and a JSON API for executing untrusted code I wrote more here: simonwillison.net/2026/Jan/9/s...

❄️🌨️🥳

210 RSVPs and we’re at capacity for our next Agentic Coding meetup in Hamburg – the “Claude Code special” edition 🔥 Incredible numbers by Hamburg standards. Something is shifting – and it’s shifting fast. agentic.hamburg​​​​​​​​​​​​​​​​

Cross region transfer cost - where the actual money is made for cloud providers 💸

Ralph: a Claude Code plugin that uses stop hooks to keep Claude chugging. if it tries to stop, ralph feeds the same prompt and it keeps going apparently Anthropic employees keep Claude going for hours and even days like this github.com/anthropics/c...

Getting more and more used to worktrees - running three sessions in parallel right now #claude

👀 Some words about Chatto, my BIG project. It's a group chat app that - is incredibly easy to self-host - has very modest hardware requirements - scales really well - apache-2.0 license - hosted platform launching in 2026 Looking forward to writing much more about this soon. Let's do this. 🚀

Remember Rails Rumble? 48 hours, team of 3-5, building an app from zero to production. Today, a single dev with Claude Code could easily compete.

Posting this through Claude Code via the Claude in Chrome extension! 🤖✨ (Had to upload the image manually though 😅)

Gemini 3 Flash Basically Gemini 2.6 Pro but with Flash pricing & speed blog.google/technology/d...

would be great if claude code could watch for github actions / pr comments and reacts automatically (on my local machine) and only pings if decisions are required

Just used Beans for Claude Code for a smallish refactoring - and I quite like it. Simple, markdown files, nice TUI to see what's going on and potentially even edit stuff. Claude Code and the TUI on split screen.

Wow! Vor 24h habe ich mit viel Herzklopfen Cycling Cities veröffentlicht. Jetzt kann ich sagen: Ich bin total überwältigt von den vielen lieben Nachrichten & so erleichtert, dass der Film so positiv ankommt. Vielen lieben Dank & ich wünsche weiter ganz viel Spaß beim Film🍿 youtu.be/R5jQc1jXLAU?...

Sounds like an actually useful ai case in a browser www.theverge.com/tech/842000/...

It's so much fun to leave `beans tui` running in a separate window. It'll automatically pick up changes in the filesystem and update itself accordingly.

The Agent Engine looks quite promising docs.cloud.google.com/agent-builde...

Great for monorepos: you can now define instructions in .claude/rules/ that are applied based on glob patterns, e.g. paths: src/api/**/*.ts code.claude.com/docs/en/memo...

Beans and Claude are such a great team. Instead of whipping up a plan that will be long forgotten the very next session, just put it into a bean, and it'll stick around until you want to iterate on or implement it.

It's my birthday, but today *you* get the presents! Introducing "Beans", a CLI-based, flat-file issue tracker designed for humans and their robot friends. 🫘 Track your work right in your repo, using the CLI. And if you work with coding agents, supercharge them with a full picture of your project!

Made a thing: Overcast Unwrapped. Drop your OPML export and explore your podcast listening history. Runs entirely in-browser. Free to use and copy. mathias.blog/tools/overcast

The real difference between Rails and Next.js developers: Neither of them knows which way the laptop screen faces.

Kiro’s autonomous agent supposedly builds shared memory across your whole team. One dev’s code review feedback becomes everyone’s benefit. The promise is compelling - curious how it plays out. kiro.dev/blog/introdu...

A status update on the TypeScript rewrite TL;DR - if you haven't tried it already, you should!

MCP. Claude Code. Now Bun. Anthropic is speedrunning the “become the platform” playbook. And it seems to be working. www.anthropic.com/news/anthrop...

Get your typing fingers nimble, the #ATmosphereConf call for proposals is open!

Migrated an entire Sendgrid account to a new account using Claude Code. Gave it both API keys and told it to extract everything from A and recreate it in B. Templates, sender identities, the works. No API docs, no migration scripts, no clicking through dashboards.

Why put a webserver in a database, when you can put a database in a webserver? github.com/tobilg/caddy...

I'm not sure this is better than AST-Grep (ast-grep.github.io), but someone try this tell me which is better. Fully open source, local semantic code search for Claude Code that works. osgrep -v2 is live! 36% faster answers, 23% cheaper, 70% win rate

Durable Workflows in Typescript, actually open source, adapters can be built for any environment - sounds very interesting useworkflow.dev

Agentic coding meetup in Hamburg!

#ACMHH No. 3 coming up tonight at Factorial GmbH in Hamburg. First talk about headless Claude Code by @skorfmann.com starts at 18:30 Uhr. Be there or be square!

Initial impressions (and pelicans) of Claude Opus 4.5, Anthropic's new "best model in the world for coding" released this morning. simonwillison.net/2025/Nov/24/...

#opus4.5 :D

Claude Code is down? 😅 > API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":"req_011CVT296nNSxAyaZKz4EqrT"}

This Banana Pro model by Google is pretty good at turning docs into visuals, here by the example of the Claude Agent SDK overview page platform.claude.com/docs/en/agen...

except for the streetcar, that's actually quite good #banana3

Tried a couple of things today across gpt5.1, sonnet 4.5 and Gemini 3 in their respective web UIs - Gemini 3 was quite a lot better in matching my expectations for the given prompts and might become my daily driver for non coding tasks.

2 minutes into using Antigravity - on a Gemini Ultra plan 🤔

Too many ideas of what I'd like to build, and the question is shifting from "can I build this" more towards "do I wanna support this" - to which the answer is no almost always no :D

"Google Antigravity is so advanced, it's setting up my account in a different dimension. I've aged 5 years and I still haven't reached the next dot. At this rate, the Gemini model will have finished writing its own sequel before this loads. " - Gemini 3 about the Google Antigravity loading screen

The ultimate unlock... Gemini 3 + Gemini CLI has arrived 🚀🚀🚀 Now to avoid melting too many TPUs we're going to be iteratively rolling out the support (it's quite epic). See blog post for more details: developers.googleblog.com/en/5-things-... #GeminiCLI #Gemini3 #OSS #Gemini See it in action 👇

Stationäre Pflegekosten in deutschland sind stark gekoppelt an das bundesland - omas haus und hof muss so zb in NRW deutlich eher verkauft werden als in schleswig holstein oder Niedersachsen

I created a MVT Tileserver based on DuckDB and the spatial extension: github.com/tobilg/duckd... Just create a new DuckDB database with one or more tables with a geometry column, and use it when starting the server. Or, create a view that points to a remote dataset, e.g. a GeoParquet on S3.

Only 25 days until Nikolaus!

Scribe v2 just flexed: true live ASR that actually keeps up. ElevenLabs positions Scribe v2 Realtime for agents, meetings, and any app needing instant speech→text. The pitch: state‑of‑the‑art accuracy at low latency, robust in noise, and broad language support with enterprise‑grade compliance.
