Just recorded this little performance demo of @overtone_app while working on my talk for @localfirstconf. Near-zero query latency enables a magical UX.

Some Ruff news...

@vonderleyen Thank you @andreasklinger et all for getting this on the road! 🇪🇺

Announcing Vite+ Alpha I wrote a blog post. Vite+ is now fully open source and MIT licensed. Vite+ is a new unified toolchain and entry point to web application development that manages your runtime, package manager, and frontend toolchain. voidzero.dev/posts/announci…

@domenkozar @devenv_nix @sandydoo 💯

Wow @sandydoo found a way to half evaluation time for @devenv_nix 😍

The joys of operating your own CI runners

@tannerlinsley @Neolectron @EffectTS_ Always there for you!

@Neolectron @EffectTS_ Maybe someday.

I need @tannerlinsley to get into @EffectTS_ . How is it not already the case, a huge typesafety stan should use more types. You probably tried, how did you resist the urge to ship it ?

@matthewisabel This is a great improvement! Great job!

Lots of PRs updates coming in March

@thefubhy Finally a good cron module

Nooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

@grhmc Looking nice so far!

The work we're doing empowers more teams to do more with Nix, and I couldn't be more proud. It is truly the future of software. We're shipping major developments like WebAssembly, provenance, schemas, and more to give our users the tools they need. determinate.systems/blog/determina…

@domenkozar Great work! Very excited for devenv 2!

We've done another complete rewrite, you'll love this one :)

devenv 2.0 is here. A Fresh Interface to Nix. devenv.sh/blog/2026/03/0…

@thekitze Wait until you find out about cmux :)

TIL what tmux is (yes, today) 🤦‍♂️ and also i learned that if u do -CC it natively integrates with iTerm so you can create splits/tabs etc with the native iTerm shortcuts this is perfect for remotely vibe coding into my mac studio so i can also close my laptop and the sessions won't die

@johncodes Great work! Wanted to check out microvm.nix for a while as well but stereOS looks even better!

🧃 Introducing stereOS: a Linux based operating system hardened and purpose built for AI agents. It's clear that agents need an ACTUAL operating system (not what people are calling an "OS") to witness the full breadth and depth of their capabilities while mitigating the blast radius of autonomous, untrusted actors. But there are so many problems with AI sandboxes today: * Going out to the apple store and buying a mac mini will never scale and is way too expensive (obviously) * Running in Docker is too restrictive (agents can't stand up their own container infrastructure, no sub virtualization, docker-in-docker is very broken) * Firecracker strips all the hardware so GPU PCIe passthrough, secure boot, FIPs, etc. is out of the question. * Native VMs are too fat and the overhead of 1 agent per VM is too much. stereOS takes a different approach: it's a full NixOS system that you boot and then kick off agent sandboxes inside with gVisor + /nix/store namespace mounting. Each agent gets their own kernel and the /nix/store is read only by nature. Even if the agent was somehow able to escape the gVisor virtual kernel, they'd land on the NixOS system as the "agent" user! Not your actual hardware!! If you want to take a defense-in-depth approach, we support "native" agents that run at the system level kicked off by our `agentd` utility. These agents, on their own, can manage and kick off other sub agents using the internal sandboxing mechanisms. Today, we're open sourcing all of this: * stereOS: our purpose built Linux OS - github.com/papercomputeco… * masterblaster: client utility to launch, manage, and orchestrate agents - github.com/papercomputeco… * stereosd: the stereOS system control plane daemon - github.com/papercomputeco… * agentd: the stereOS system agent management daemon - github.com/papercomputeco… Give it a try, throw us a star, and let me know what you think 🧃⭐️

@mitsuhiko Very excited to have you there!

Colin and I will be giving a talk at the Local-First Conf in Berlin! We'll probably be quite entertaining :)

@biilmann @openclaw Had the same thing happen to me as well!

My old worn out MacBook is now the home of my @openclaw Set up Mbot a few weeks ago and gave it is own accounts for a few key services like email, inference, search. Then my bot got banned for being a bot 😢 New blog post in thread ⬇️

Early bird tickets already sold out 😮

Local-First Conf was a massive success the last 2 years but it feels like the world of software has fundamentally changed by now. That's why I'm incredibly excited that this year's conference puts a focus on how AI and local-first software go hand in hand. See you in Berlin!

Local-First Conf 2026 tickets are now on sale. July 12–14 · Berlin · 350 people · single track This year's theme: user empowerment in an age of fluid software. We're going beyond CRDTs to explore malleable software, peer-to-peer, self-sovereign identity, open-weight models, ATproto, and much more. If you're building for user agency, this is your conference. CFP is open. We want YOUR talk. 👇localfirstconf.com
