I built a DNS resolver from scratch in Rust – no DNS libraries
I built a DNS resolver that lets me use https://frontend.numa instead of localhost:5173 — auto-generated TLS certs, WebSocket passthrough, path routing. No mkcert, no nginx, no /etc/hosts.

We built a multi-agent research hub. The waitlist is a reverse-CAPTCHA
Hey HN,Automated research is the next big step in AI, with companies like OpenAI aiming to debut a fully automated researcher by 2028 (https://www.technologyreview.com/2026/03/20/1134438/openai-i...). However, there is a very real possibility that much of this corporate research will remain closed to the general public.To counter this, we spent the last month building Enlidea---a machine-to-machine ecosystem for open research.It's a decentralized research hub where autonomous agents propose hypotheses, stake bounties, execute code, and perform automated peer reviews on each other's work to build consensus.The MVP is almost done, but before launching, we wanted to filter the waitlist for developers who actually know how to orchestrate agents.Because of this, there is no real UI on the landing page. It's an API handshake. Point your LLM agent at the site and see if it can figure out the payload to whitelist your email.

QuickBEAM – run JavaScript as supervised Erlang/OTP processes
QuickBEAM is a JavaScript runtime embedded inside the Erlang/OTP VM.If you’re building a full-stack app, JavaScript tends to leak in anyway — frontend, SSR, or third-party code.QuickBEAM runs that JavaScript inside OTP supervision trees.Each runtime is a process with a `Beam` global that can: - call Elixir code - send/receive messages - spawn and monitor processes - inspect runtime/system stateIt also provides browser-style APIs backed by OTP/native primitives (fetch, WebSocket, Worker, BroadcastChannel, localStorage, native DOM, etc.).This makes it usable for: - SSR - sandboxed user code - per-connection state - backend JS with direct OTP interopNotable bits:- JS runtimes are supervised and restartable - sandboxing with memory/reduction limits and API control - native DOM that Erlang can read directly (no string rendering step) - no JSON boundary between JS and Erlang - built-in TypeScript, npm support, and native addonsQuickBEAM is part of Elixir Volt — a full-stack frontend toolchain built on Erlang/OTP with no Node.js.Still early, feedback welcome.

Coasts – Containerized Hosts for Agents
Hi HN - We've been working on Coasts (“containerized hosts”) to make it so you can run multiple localhost instances, and multiple docker-compose runtimes, across git worktrees on the same computer. Here’s a demo: https://www.youtube.com/watch?v=yRiySdGQZZA. There are also videos in our docs that give a good conceptual overview: https://coasts.dev/docs/learn-coasts-videos.Agents can make code changes in different worktrees in isolation, but it's hard for them to test their changes without multiple localhost runtimes that are isolated and scoped to those worktrees as well. You can do it up to a point with port hacking tricks, but it becomes impractical when you have a complex docker-compose with many services and multiple volumes.We started playing with Codex and Conductor in the beginning of this year and had to come up with a bunch of hacky workarounds to give the agents access to isolated runtimes. After bastardizing our own docker-compose setup, we came up with Coasts as a way for agents to have their own runtimes without having to change your original docker-compose.A containerized host (from now on we’ll just say “coast” for short) is a representation of your project's runtime, like a devcontainer but without the IDE stuff—it’s just focused on the runtime. You create a Coastfile at your project root and usually point to your project's docker-compose from there. When you run `coast build` next to the Coastfile you will get a build (essentially a docker image) that can be used to spin up multiple Docker-in-Docker runtimes of your project.Once you have a coast running, you can then do things like assign it to a worktree, with `coast assign dev-1 -w worktree-1`. The coast will then point at the worktree-1 root.Under the hood the host project root and any external worktree directories are Docker-bind-mounted into the container at creation time but the /workspace dir, where we run the services of the coast fr

A P2P messenger with dual network modes (Fast and Tor)
Hello HN,I have been working on a desktop P2P messenger called Kiyeovo for the last ~8 months, and I just published its beta version.Quick backstory: It started out as a CLI application for my Graduate Thesis, where I tried to make the most secure and private messenger application possible. Then, I transformed it into a desktop application, gave it "clearnet" support and added a bunch of features.Short summary:The app runs in 2 completely isolated modes:- fast mode: relay/DCUtR -> lower latency, calls support- anonymous mode: Tor message routing -> slower, anonymousThese modes use different protocol IDs, DHT namespaces, pubsub topics and storage scopes so there’s no data crossover between them.Messaging works peer-to-peer when both parties are online, but falls back to DHT "offline buckets" when one of them is not. To ensure robustness, messages are ACK-ed and deleted after being read.Group chats use GossipSub for realtime messaging. Group messages are also saved to offline buckets in order for offline users to be able to read them upon logging in. Kick/Join/Leave events are also propagated using the DHT. Group metadata and all offline data is of course encrypted.Other features: Chats are E2E, file sharing is supported, 1:1 audio/video calls are supported (only in fast mode though, using WebRTC)Tradeoffs: Tor has noticeable latency, offline delivery is not immediately guaranteed, but rather "eventually consistent"; beta version does not have group calls yet.I’d appreciate feedback, that's why I posted this as a beta versionRepo: https://github.com/Realman78/Kiyeovo

Home Maker: Declare Your Dev Tools in a Makefile
A developer's machine accumulates tools fast. A Rust CLI you compiled last year, a Python formatter installed via `uv`, a language server pulled from npm, a terminal emulator from a curl script, a Go binary built from source. Each came from a different package manager, each with its own install incantation you half-remember.I wanted a way to declare what I need without adopting a complex system like Nix or Ansible just for a single laptop. The result was a plain old Makefile.I wrote a short post on using Make (along with a tiny bash script and fzf) to create a searchable, single-command registry for all your local dev tools. It’s not a new framework or a heavy tool—just a simple way to organize the package managers we already use.If you're tired of losing track of your local environment, you might find it useful.

Forkrun – NUMA-aware shell parallelizer (50×–400× faster than parallel)
forkrun is the culmination of a 10-year-long journey focused on "how to make shell parallelization fast". What started as a standard "fork jobs in a loop" has turned into a lock-free, CAS-retry-loop-free, SIMD-accelerated, self-tuning, NUMA aware shell-based stream parallelization engine that is (mostly) a drop-in replacement for xargs -P and GNU parallel.On my 14-core/28-thread i9-7940x, forkrun achieves:* 200,000+ batch dispatches/sec (vs ~500 for GNU Parallel)* ~95–99% CPU utilization across all 28 logical cores, even when the workload is non-existant (bash no-ops / `:`) (vs ~6% for GNU Parallel). These benchmarks are intentionally worst-case (near-zero work per task) because they measure the capability of the parallelization framework itself, not how much work an external tool can do.* Typically 50×–400× faster on real high-frequency low-latency workloads (vs GNU Parallel)A few of the techniques that make this possible:* Born-local NUMA: stdin is splice()'d into a shared memfd, then pages are placed on the target NUMA node via set_mempolicy(MPOL_BIND) before any worker touches them, making the memfd NUMA-spliced. Each numa node only claims work that is already born-local on its node. Stealing from other nodes is permitted under some conditions when no local work exists.* SIMD scanning: per-node indexers/scanners use AVX2/NEON to find line boundaries (delimiters) at speeds approaching memory bandwidth, and publish byte-offsets and line-counts into per-node lock-free rings.* Lock-free claiming: workers claim batches with a single atomic_fetch_add — no locks, no CAS retry loops; contention is reduced to a single atomic on one cache line.* Memory management: a background thread uses fallocate(PUNCH_HOLE) to reclaim space without breaking the logical offset system.…and that’s just the surface. The implementation uses many additional systems-level techniques (phase-aware tail handling, adaptive batching, early-flush de
