Implement Livebook Desktop with Tauri by wojtekmach · Pull Request #3112 · livebook-dev/livebook Already publishing as separate nightly builds: https://github.com/livebook-dev/livebook/releases/tag/nightly TODO: icons

Powered by Tauri github.com/livebook-dev...

Same tech we're using in the Tidewave desktop app.

You could already run Livebook in Linux since day 1.

But this makes it even easier: just a single install that includes everything (Elixir, Erlang/OTP).

Livebook desktop now supports Linux!

GitHub - PJUllrich/devcontainer: A Claude-based Devcontainer for Elixir development A Claude-based Devcontainer for Elixir development - PJUllrich/devcontainer

⚠️ Tiny soft-launch ⚠️

I built a devcontainer that makes it safe(-er) to run Claude Code with "--dangerously-skip-permissions" for Elixir/Phoenix projects and it comes with Tidewave too! It's based on Anthropic's reference but made safer and tailored to #ElixirLang

> to have a standard dev container that designers could spin up fully in the browser, with access to Tidewave Pro + Claude/Codex/whatever,

We considered that and asked our Discord community for feedback, but most people wanted code review instead.

So, we'll see. But it would be pretty cool!

Soft launch announced first in the Discord. We get feedback, iterate, and announce publicly like a week later.

The Nerves Starter Kit prototype (right) and the Goatmire name badge (left). The starter kit screen is 50% larger, with higher resolution. They're running the same software, but the starter kit text is smaller due to the higher resolution

The Nerves Starter Kit prototype side view. There are two arms that can attach to the back which tilt the display up at a 15° angle. The stand can be removed, and instead the whole device can be wall mounted for a picture-frame like experience instead

I had the pleasure of revealing some of the latest updates for the Nerves Starter Kit project last night at the monthly @nervesmeetup.eu! There were some really good discussions, and I definitely woke up today really energized from the feedback we got :)

Your agent just made a ton of CSS changes and you’re trying to make sense of them?

Same here. I was curious if Tidewave could help me understand it all visually.

Here’s how it went. SO COOL!

If you're on Tidewave's Discord, you already know this. ;)

Bluesky Map Interactive map of 3.4 million Bluesky users, visualised by their follower pattern.

I made a map of 3.4 million Bluesky users - see if you can find yourself!

bluesky-map.theo.io

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

A new and AWESOME 🤩 project of our book is coming!

Build an Etch A Sketch, input from your Nerves-powered Raspberry, and visualize within Livebook. 🔥

GitHub - puemos/craftplan: Self-hosted software for managing artisanal D2C micro-businesses Self-hosted software for managing artisanal D2C micro-businesses - puemos/craftplan

This person made a production management tool for his spouse's bakery in #ElixirLang + Ash + LiveView. It's super valuable to have an codebase like this be open source for people trying to get into that tech stack. 💜

Explaining a product in a new category is hard.

Every copy change is a chance to understand it better.

Today’s Tidewave website update feels like one more step forward.

Let me know what you think.
