What started as “please remember my dev ports” became an SNI router that hands the original TLS socket to Phoenix—no TLS termination, no relay, real client IP. Inspired by Chris McCord and enabled by @mtrudel.bsky.social 's Bandit/Thousand Island. cookbook.geuer-pollmann.de/elixir-beam/...

Been hacking on an Elixir port of Karpathy's autoresearch — an LLM agent that designs and trains GPT models autonomously, overnight. Turns out the BEAM is (unsurprisingly) a natural fit: hot code reloading for experiments, multi-GPU fault tolerance, LiveView to watch it think.

Still very rough, but it's fun to wake up to a trail of experiments you didn't run yourself. github.com/chgeuer/ex_a... #elixirlang

Found the time to publish an Elixir LiveView app that allows you to run Github Copilot sessions in the browser and see the full fidelity about tool calls. And review previous sessions. And backup sessions. And continue. And Claude, Codex, and Gemini github.com/chgeuer/copi...

Last week (when OpenAI's symphony came out), I thought: Replace github with local git, replace Linear with Beads, and slap some Phoenix Liveview on top. Well, and some Github copilot and @mikehostetler.bsky.social Jido github.com/chgeuer/jido... #elixirlang

Your Elixir Phoenix projects are fighting over port 4000 on your machine? 😅 Fix it forever: github.com/chgeuer/phx-... #myelixirstatus #elixirlang

Your AI coding agent can iex --remsh into your running BEAM node. Agents use a single shell script + a skill definition. Now they inspect GenServer state, trace processes, hot-reload fixes (Soul of Erlang&Elixir), but the operator is an AI. 🤯 cookbook.geuer-pollmann.de/elixir-beam/... #ElixirLang

And ... fixed

It’s a bit like tidewave without all the UI stuff, just a bunch of shell scripts

Having a distributed Erlang/Elixir cluster with Erlang distribution running over Azure Relay Hybrid Connections, not too shabby. Allows me to do cross-site clustering without Wireguard etc. #ElixirLang #Elixir #Erlang

Was wondering why @arvidkahl.bsky.social switched from #elixirlang to PHP, got the answer in the most recent podcast episode. Despite my big appreciation for Elixir and Phoenix, certainly understand the reasoning from a founder perspective. thebootstrappedfounder.com/the-ownershi...

Here'a a little #elixirlang library prototype for having plain old Elixir structs (POCOs, but POESs). No GenServers, just immutable data structures. Use at your own risk, and check-out the @livebook.dev here: github.com/chgeuer/reac...

I need an Elixir library to have properties on a struct transitively automatically updated, when other properties change. Is there already something (yes, I know, @ash-hq.org has calculated fields). Just wanted some POES (plain old elixir structs) 😐 #elixirlang

Wrote a small library to play with rendevouz hashing, similar to HCA Healthcare's Project Waterpark from @bryan-hunter.bsky.social , and a visualization in @livebook.dev to show actor placement and replication across the cluster, based on the ID of the patient (or actor) @elixir-lang.org
