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.
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

Taking Chris McCord's idea one step further. What if #elixirlang accepts a TCP connection, chats with the client, then hands the live socket to a Rust process? One unbroken TCP stream, two languages. SCM_RIGHTS is wild. 🦀🔮 github.com/chgeuer/hand_off_to_rust Really hard /cgi-bin vibes..

Inspired by Chris McCord's tweets yesterday — built a blue/green hot deployment demo in Elixir. Accept a TCP connection on v1 on BEAM node 1, then live-upgrade to v2 mid-session using SCM_RIGHTS FD passing between peer nodes. The client never disconnects. 🔵🟢 github.com/chgeuer/blue_green

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

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...
![Elixir code:
defmodule Chain do
use ReactiveStruct
defstruct ~w[base step1 step2 final]a
computed(:final, deps: [:step2], do: step2 * step2)
computed(:step1, deps: [:base], do: base * 2)
computed(:step2, deps: [:step1], do: step1 + 10)
end
chain = %{final: 256} = Chain.new(base: 3)
chain = %{final: 400} = Chain.update(chain, base: 5)](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:bohbypttsuiw4knejkcs2ycl/bafkreiexwdm3i4e3ean4dpncg7ugmyniyyo2kpyrjindx5zubglxkqohjq)
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
![Elixir code
defmodule SomeStruct do
use ReactiveStruct
defstruct ~w{x2 x3 x ya yb y sum}a
computed(:y, deps: [:ya, :yb], do: ya - yb)
computed(:x, deps: [:x2, :x3], do: x2 + x3)
computed(:sum, deps: [:x, :y], do: x * y)
end
SomeStruct.new(x2: 2, x3: 3, ya: 4, yb: 5)
|> IO.inspect(label: :a)
|> SomeStruct.update(x2: 10)
|> IO.inspect(label: :b)

Are there #ElixirLang #AshFramework folks out there using DNSimple for their application‘s DNS needs? Would love a little ping
Giving Claude a little module to party in is working nicely, also codified in usage_rules.
