If you are facing issue setting up @AmpCode with OpenCode Go subscription, edit the Models field to the following format: `<provider>/<model-id> -> <model-id>`. E.g. `deepseek/deepseek-v4.1-flash -> deepseek-v4.1-flash`

You will still get error when clicking Check Access though

Yesterday, during my ElixirConf keynote, I showed how Livebook/Kino can plug into Elixir's v1.14 dbg and allow you to debug and rearrange |> pipelines on the fly!

Did you know that team #PostgresProfessional published Part II of our "@PostgreSQL 14 Internals" #freebook that got positive reference from @martinkl and other experts of the #database world? If no, please read it on our website: https://t.co/ZPs7aGJcxR #PostgreSQL #opensource

[Livebook @livebookdev]

Introducing the Livebook app.

We want Livebook to be accessible to as many people as possible. That's why we built this.

It's the simplest way to install Livebook on your machine.

This book on PostgreSQL internals looks like a great resource on isolation levels, concurrency control, and various storage engine topics https://t.co/ZkkpKuNbbB

[Andrea Leopardi @whatyouhide]

New lovely @elixirlang feature just landed in main: "dbg" ✨

It's kind of like IO.inspect/2, but specifically tailored for debugging. I think it looks fabulous. 🎩

It's inspired by @rustlang, but has some superpowers too. See the thread 🧵🦸‍♀️

[Sugu Sougoumarane @ssougou]

It's a wrap!

This series shows a way to conceptualize consensus algorithms, where Paxos and Raft are a special case. But more flexible implementations are possible: @vitessio lets you specify arbitrary durability rules through plugins. @planetscaledata https://t.co/PdgxvIf4wy

[Recurse Center @recursecenter]

In honor of RC's 11th birthday this month, we're offering an extra 11 $1,000 grants for our fall batches to women, trans, non-binary, and/or Black programmers! 🎉

Apply by July 21 (earlier is better).

Please spread the word!

Nice, @readysetio is sharing the source for parts of ReadySet (the production-ready Noria) so you can easily try it out directly yourself 🎉

Episode 103: We learn about @VaxineIO, an @ElixirLang layer built on top of a distributed CRDT-based @erlang_org DB called Antidote. We cover CRDTs, the CURE protocol, and what @VaxineIO brings to the party. #ElixirLang #Database https://t.co/0MmDaWHjyp

Today during my @ElixirConfEU keynote I announced there is an ongoing PhD scholarship for researching and developing a type system powered by set-theoretic types for Elixir.

Here is a quick summary... 🧵 [1/6]

[Andrey Nᴏᴠɪᴋᴏᴠ - @envek.bsky.social @Envek]

— PostgreSQL, did you update all these megabyte-long JSON I gave you?
— Yes
— What did it cost?
— Everything… all the IO on the server.

Let’s talk about how PostgreSQL stores JSONB (yep, it will be a thread about TOAST) 🧵

[Kai Wern @kw7oe]

@darr1s @recursecenter Thanks! Same to you as well!

[Kai Wern @kw7oe]

For the past 6 weeks, I have been attending the @recursecenter (RC). The journey has been fascinating so far! Here's a longer write up about my first 6 weeks in RC: https://t.co/PVYOMAGfwW

[Mitchell Hashimoto @mitchellh]

Nomad 1.3 has built-in service discovery, so you can get service discovery out of the box in a single binary without adding on something like Consul. This should make adopting Nomad much easier, and especially helps smaller scale use cases. 😍 https://t.co/hyS8fCGQTS

[Kai Wern @kw7oe]

@recursecenter Also, consider reading RC self-directives: https://t.co/QG5pNaGSYx
It resonates a lot with how I approach learning. You'll definitely benefits from it even you're not attending RC.

[Adolfo Neto in on BlueSky and on Mastodon @adolfont]

Now there is a Livebook for Elixir code smells thanks to @crisguade:

@livebookdev @elixirlang Thanks for clarifying it! Will definitely do so 💯

Wrote a post about writing a simple Redis Protocol parser in Elixir with #Livebook support. You can use this link to run it in Livebook: https://t.co/idUvrIsxqj

It's part of my implementing mini Redis in Elixir series. One challenge I faced is test rerun:

#MyElixirStatus

[Kai Wern @kw7oe]

I tried looking into ExUnit docs to find out ways to reset the state or rerun the tests but have no luck with it.

I also tried Livebook branch out section, but didn't seem to be working as well.

Please let me know if you know a better way to do this!

[Kai Wern @kw7oe]

Here's a gist: https://t.co/cfKNI6YINw

With it, I only need to define the test code once. When I need to rerun the test, I just recreate the module and run the test. Hacky but works.

There's probably better way to do this. Here's what I tried:
