The wildly opposite ai programming takes are a sign the folks calling it over are missing what's possible, because they were limited by what they came from. Dream bigger!

others: "it's over, guess it's all rust from here"
me: "omg there's so many things I can build in Elixir"

Hooray! @hugobarauna has done a fantastic job improving the onboarding experience for Tidewave, smoothing the steps to select your framework and configuring your first agent!

New version of the Elixir Language Tour is here! 🚀

In this release we vastly extended the Processes chapter, so you can learn & play with core OTP components: Links, Agents, GenServers and Supervisors.

The tour runs fully in your browser – all thanks to Popcorn 🍿

The Erlang VM has all these incredible things. Did you know you can boot a `:peer` node as a VM within the VM, fully meshed? Enter `FlyDeploy.BlueGreen` - "hot bluegreen" deploys where we spin up the new incoming VM, then cutover seamlessly:

Currently I am test upgrading a couple of @elixirphoenix applications to Elixir v1.20 rc1 just to run the tests and see how the new type system works. It has found and helped to fix bugs in every one of them.

Quite powerful without any additional human work.

Introducing Sagents -- an open-source #ElixirLang framework for building #AI agents with human oversight, composable middleware, and real-time @ElixirPhoenix LiveView integration.

Built on OTP. Each agent is a supervised GenServer.

We just launched a Task Board for Tidewave, which allows sharing tasks across agents sessions. @hugobarauna has been using it for a while, using one chat to plan and spec tasks, while another chat is getting items from the board and implementing them!

Streams are one of @elixirphoenix LiveView’s superpowers, and LiveDebugger v0.5.0 lets you finally see them in action 👇

In LiveView, we keep the state in one place - the server - and it simplifies a lot. But sometimes the state on the client is preferred, or even necessary, and we can't use LiveView for that part.

Unless we have a LiveView that runs on the client 👀

Using Popcorn, we managed to run LiveView fully in the browser – here's a POC 🎉

The approach is to have a fully client-side LiveView rendered by a server-side one, and they can communicate with each other.

Last week we used https://t.co/KNZbk8apeI to find accessibility issues on @37signals's Campfire (Rails), @shadcn's UI (Next.js), and our own @livebookdev (Phoenix), and we were able to automatically fix 79% of the issues we found, 2x more than using Claude Code standalone.

It's been a while since last Elixir Stream Week...

...which is why we're starting to think of pulling another edition out 👀

In the meantime, here's a recap from the previous one, where @chris_mccord live-coded a real-time Twitch clone. Full video in 🧵
