Hello #ElixirLang

Does anyone look for principal/senior level developer? Either permanent or contract.

I have experience in performance optimisations and observability of Elixir and Erlang codebases.

💥 Elixir PSA: update Plug *immediately* to the latest possible (1.20.1)

The latest CVE makes it trivially easy to DOS a plug based server.

cna.erlef.org/cves/CVE-202...

This one is a doozy stay safe out there and keep your deps updated!

TIL about `LiveView.static_changed?/1` 💜

Clients that connect to the new deploy of an #ElixirLang LiveView app won't load the latest JS/CSS (that only happens on a hard refresh). `static_changed?/1` gives you an easy way to show an alert suggesting they refresh manually.

🚨 Please update "decimal" 🚨

A *single* calculation like:

Decimal.new("1e1_000_000_000") |> Decimal.add(1)

will OOM your application. Poof. Adios. Auf Wiedersehen.

My Team and I are looking for a second senior elixir developer to join us at AZAV Pilot! You’d be joining me in developing and improving our main Phoenix/LiveView SaaS and internal tools.

#ElixirLang #ElixirPhoenix #hiring

In #Phoenix #LiveView v1.1.0-rc.0 we shipped `:key` support for comprehensions in HEEx. The idea was to finally be able to have change tracking in comprehensions. We did this by leveraging LiveComponents. Sounds easy enough, right? There were some problems though. A thread. #MyElixirStatus

The second RC for #Phoenix #LiveView 1.1.0 is out now with a bugfix for an issue affecting template re-rendering when using `:let`.

I did not post about rc.0 last Tuesday, but it's a quite big release, so please give it a spin and open up issues in the repo if you find any problems! #MyElixirStatus

I wrote about something very close to my heart: how to make ALL the tests async in @elixir-lang.org.

Day 24 — Svelte now handles `class` attributes with github.com/lukeed/clsx. Much more powerful than the `class:` directive, but since this is Svelte you still get dead code elimination of unused styles!
