Elixir project dependencies compilation with Elixir 1.19.0-rc.1 measured on my MacBook Pro M1 Max (10 cores) is 2.3x faster than with 1.18.4. Crazy! 🤯🚀⚡

This is very cool! 😮
What a WILD day at #Goatmire! I finally unveiled the surprise that @lawik.bsky.social and I have been cooking up for the last few months - every attendee received a Nerves-powered e-ink name badge!
I had a blast on stage presenting the project and the process of how to design hardware for Nerves

Introducing `Ash.TypedStruct`, a nice convenient wrapper around creating struct types 🎉. It doesn't do typespecs, as we're waiting for the type system to add generated types in Ash, but you get all the other benefits, including automatically supporting OpenAPI & AshGraphql.

LLMs are cool and stuff, but one technological advancement I am still waiting for is a silent boiling kettle.

Has something changed with this in the meantime? #elixirlang
I mean this in the most positive way, but I feel like the "Official Elixir LSP" effort deserves some communication towards the community. Many (I hope) of us (or our companies) have set up sponsorships to help it, but after 1/2 year we have no idea what's going on. Or I missed something? #elixirlang

I hope I'll see a day when we won't care about files and directories when programming. Just modules and functions (or types for that matter). Having to think about the file structure feels redundant. I want to work with the code similar to a mind mapping tool.

I keep a draft PR open for our app to try CI against the main Elixir branch (1.19). There were so many warnings I thought it's nonsense. But then I looked closer and realized it found calls to non-existing fields on schemas being passed through multiple layers without pattern matching 🤯 #elixirlang

Any idea why am I seeing `:erlang.binary_to_existing_atom("...")` in my @appsignal.com error? Three dots instead of the problematic string isn't very useful. AppSignal is showing a warning "Backtrace regex did not match" for that line, but I have no idea what that means. #elixirlang

That feeling when trying to configure NeoTest in LazyVim as a total noob only to realize after a few days, that I had a typo in otps vs opts. 🤦♂️😅

Euruko 2010 in Krakow was the only real tech conference I've ever attended. Now, 15 years later, I'll be returning to Krakow—this time for the @elixirconfeu.bsky.social but still with @josevalim.bsky.social 😊 Feels symbolic in a way. #elixirlang

I wrote a new article exploring how set-theoretic types (the foundation of Elixir's type system) could address how many statically typed languages do not allow libraries to evolve their data definitions in a backwards compatible manner: dashbit.co/blog/data-ev... - be warned, it is a long one.
Data evolution with set-theoretic types - Dashbit Blog
In this article we explore the challenges of data evolution in static typing and explore type safe solutions.
