Now that Phoenix 1.8 and LiveView 1.1 have been released, here's a little something I've been working on:

LiveView can be a bit intimidating for a mostly backend Elixir engineer, at least it was for me, so here's some basics to get you started

#ElixirLang

Phoenix 1.8.0 is released! 🎉

Release ElixirLS 0.29.0 · elixir-lsp/elixir-ls v0.29.0: 4 August 2025 Highlights Added Call hierarchy provider implementing LSP textDocument/prepareCallHierarchy, callHierarchy/incomingCalls and callHierarchy/outgoingCalls ElixirLS now bundles...

New elixir-ls release!

> ElixirLS now bundles a number of experimental LLM oriented tools exposed as custom commands and a builtin MCP server. The tools focus on model friendly text interface instead of typical IDE oriented LSP API methods

cchistory: Tracking Claude Code System Prompt and Tool Changes Exploring how to track and analyze changes in Claude Code's system prompts and tools to understand AI assistant evolution

Hacked Claude Code to see what it does. It's kinda funny.

I don't hate it but why? 🙃

`M3u8::Reader.new.read` <- this is an anti-pattern:

1) you create a pointless intermediate state and waste memory
2) if a constructor changes, all those calls will have to be updated
3) it is actually not clear what's going on because `.new` may do a lot of weird stuff

💔😢

Yes, a very kind person with an amazing sense of humor. A fantastic public speaker too.

We lost a wonderful human being this week.

I wish we did swap our talks back at RubyConf in Braga to troll the audience and see if they will realize you're not me, and I'm not you, like you wanted to.

You were THE Piotr S. of the Ruby community, as we liked to joke.

I'll be missing you Piotr.

Elixir and @gleam.run have both landed in the top 3 most admired languages in the 2025 @stackoverflow.com.web.brid.gy Developer Survey. 👏

According to devs worldwide, Gleam is turning heads while Elixir continues to impress.

Announcing drops_relation 0.1.0 - a new #ElixirLang library which provides a high-level relation abstraction on top of Ecto! 🎉

Please test it out and let me know what you think. PostgreSQL support should be quite good, SQLite works but inference is limited due to missing type info from migrations.

Would love to see it too :)

One thing I wanted to clarify - I built technical foundation for slices via dry-system gem, and came up with the idea to call them slices in Hanami *however* the concept of slices was first introduced in Merb back in 2008.

I just carried the Merb torch.

I've recently become a fan of igniter btw :)

Yes this should mostly boil down to coming up with nice conventions and a little bit of orchestration to ease setup.

This is a really cool project! github.com/bradleygolde...
Think of it like a Quickstart for working with claude code and Elixir projects, that leans on all the conventions we've been working on like tidewave & usage rules.
#ElixirLang

Small PSA: If you use "Money.divide/2" in :money (not :ex_money) then please update your Money version and replace it with "Money.div/2" since the "divide/2" function can lead to Out-of-Memory (OOM) issues:

Actually, I run CI inside my docker container, and I can reproduce it easily locally, I struggled a lot with other stuff, like juggling 3 Ecto repos and 2 adapters, and 3 apps for testing, and deps, and dealing with caching issues, and so on and so forth 🙃

🤦🏻🔨

Yes and I'm determined to build at least a PoC for Phoenix at some point later this year

Small delay as I hit various issues when writing doctests yesterday, but things are resolved and I'll be releasing it today 🙃

I just released 0.2.0 of Inherit. Lots of improvements, feels very solid now. Have been using it heavily in GenDOM

#ElixirLang

Hey Elixir friends! :) 🚀 Hologram v0.5.0 is here!

Major performance leap: milliseconds → microseconds execution times + 50x rendering speed improvements!
and... Session/cookie management, live reload, incremental compilation, new pointer/mouse events.

#Hologram #Elixir #ElixirLang #BEAM #WebDev

A screenshot of code showing the new `match_mode` option for multi select fields. ``` <Cinder.Table.table resource={MyApp.Book} actor={@current_user}> <:col field="tags" filter={:multi_select} filter_options={[ options: [ {"Fiction", "fiction"}, {"Bestseller", "bestseller"}, {"Award Winner", "award_winner"}, {"New Release", "new_release"} ], match_mode: :all # Records must contain ALL selected tags ]} > ```

Cinder v0.5.0 has been released, with fixes for array fields including a new `match_mode` option - select records where any or all of the array values match the filter! hexdocs.pm/cinder/

Gonna release drops_relation 0.1.0 on Monday. You can check out the README to see how the API looks like.

I'm really excited about this one 🙃

#ElixirLang #SQL #OpenSource

This is not about what's possible to do, but more about what is built into the framework and promoted as a "blessed way" of handling params. IIRC Phoenix doesn't have that.

ps. I just noticed that you're one of the authors of sentry-elixir which I happen to maintain now so ^5!

Thanks for acknowledging this and engaging then. I appreciate it a lot 🙂

I love Ecto. I even played a role helping with architectural design of Ecto 2.0.

This lib is one of the reasons why I decided to dive into Elixir eventually and make it my go-to language 💜

Congrats!

That's why I wrote around 5k LOC of OSS Elixir code during the last month or so 😆
