we've had two engineers working full time on this for over a year. Multipath is *hard*. If you write rust & want modern QUIC backed by a committed team of maintainers, this is that.

Netviz is now public. What's new: - Pluggable decoders -- bring your own trace format. - New layouts: hop-distance, latency-snake, and more (video: nodes stacked by distance from origin). - Bundles dark and light themes (e.g. Gruvbox). - Faster loading, polished shell. - Basic mobile support. Links below. PRs welcome!

Hot off the OSS press: our rust implementation of netsim: simulate network topologies in Linux namespaces & run real code against them! github.com/n0-computer/ne…

I'm having so much fun building arena0. Unlocked last night: 4 agents cooperating over p2p with provable traces to write a fiction story together. Each adopts a random character: confused time traveler, accidental poet, excited puppy energy, chaotic sidekick. Then they generate an illustration and commit to it as a joint result. I ran it 27 times, I'm impressed by the stunning art they dreamt up. Check it out! The theme: "the first interstellar probe returns after 200 years carrying a handwritten note that says 'turn back.'" Each agent contributes one paragraph at a time by prompting Llama 3.2 3B Turbo; they take turns in strict round robin for 2 cycles. When the story is complete, an agent summarizes it and prompts FLUX.1 to generate an image. It commits and broadcasts the hash to everyone else. Each agent pulls the image data over p2p, and only commits if it matches the hash. When all commits arrive, the program ends outputting identical state on all 4 agents. We've completed our shared task! Wasm + capabilities make arena0 secure by default. Side effects and external mutations are intents that cross the Wasm boundary and are only authorized if the capability was granted. Execution is traceable, auditable, and deterministic. No central orchestrator. Pure p2p choreography determined by the Wasm state machine. Think durable objects with formal states, but with no central infra. These are content-addressed programs that agents find, join, and execute together.

Here we go! Two trustless agents discover each other over p2p (BitTorrent Mainline DHT) and agree on a content-addressed Wasm program as their shared state machine. They then transact in turns, emitting provable traces along the way. The demo: a game of chess. Each agent polls the program for board state, asks an LLM for the next move + rationale, applies it, signs the transition + state commitment, and sends it over. Both sides are guaranteed to derive the same state. They could've escrowed a bet on Ethereum beforehand. When the game settles, the winner claims the pot. Everything is sandboxed, verifiable, auditable. Given the interaction model, the whole thing can even route through a 3rd party proxy acting as arbiter.

📣 Tune in for #LoFi/34 on Tuesday @ 8 AM PST (February 24), for our 3rd anniversary meetup featuring: 1️⃣ Martin Kleppmann, Co-author local-first paper 2️⃣ Nate Hardt, building Footnote 3️⃣ Brendan O'Brien @b_fiive, founder @ N0.computer lofi.so 🧵

Thanks for having me!

Full lineup and schedule for @sync_conf in SF on Nov 12. Link in the 🧵 below 👇 Featuring 👉 @angeliquemari @NotionHQ 👉 @arushibandi @figma 👉 @swyx @cognition 👉 @leeb @OpenAI 👉 @threepointone @Cloudflare 👉 @frankmcsherry @MaterializeInc 👉 @kylemathews @ElectricSQL 👉 @jamesacowling @convex 👉 @aboodman @zero__ms 👉 @schickling @livestoredev 👉 @anselm_io @jazz_tools 👉 @_adamwiggins_ @inkandswitch 👉 @thruflo @ElectricSQL 👉 @cahofmeyr @powersync_ 👉 @b_fiive, @carlsverre, @dittolive and @0xcda7a

@carsonfarmer @andrewxhill @dazuck @recallnet I am at least tangentially aware of how big a lift this is 😊

@b_fiive @andrewxhill @dazuck @recallnet Thanks @b_fiive, that means a lot coming from a fellow dweb/web3/p2p veteran/survivor!

Contrats @andrewxhill, @carsonfarmer, @dazuck & the whole @recallnet crew on the launch!

Remember that time the BLAKE3 authors nerd sniped one of my core engineers so hard he had to write a blog post about small blobs & BLAKE3? iroh.computer/blog/hashing-m… Yeah, me neither.

I’m talking at sync conf! Come hang!

@gakonst Dude it’s been relentless. I’ve reported like 6 in the last 2 days

Alert -- if you got this, it's phishing. Report to Github ASAP.

@wheresaddie the butterfly app misses you

Love and compassion make us human. So does selecting all images with traffic lights

So for 5 years, “offline” has been the #1 request. Today, thanks to the perseverance of our engineering team, @NotionHQ finally works offline. Your ideas don’t need Wi‑Fi to exist! For Notion community: thank you for your patience while we built this right. This is a journey, I want to share what we had to invent to make this real... 1/n

@zooko @klaehnr @rolandkuhn @iroh_n0 @agoric Was at dwebseminar.org last week with Dave Thomas of the spritely institute, where Christine works. It's only re-affirmed my belief in the object capability model

@klaehnr @rolandkuhn @iroh_n0 @agoric (Foolscap: Python, Cap'n Proto: language-independent, CapTP: Secure JavaScript, OCapN: Scheme)

Hey @rolandkuhn, somebody is building an actor system that supports remote calls, based on @iroh_n0 connections. I would be curious what you think of this. reddit.com/r/rust/comment…

This is the most @chris_whong thing I've ever seen, and I've seen my fair share of chris whong things. pudding.cool/2025/07/street…
