Really excited for this one. My colleague Matt knows his stuff when it comes to frontend performance, and he’s come up with tricks I’ve never seen anyone else even hint at.

✏️ My pull request for a refund feature grew past 3,000 lines. At that size, a code review can't do its job: reviewers miss things or rubber-stamp it. So I stopped adding to it and started extracting the unrelated fixes and tests into their own PRs. mikezornek.com/posts/2026/9...

⚗️ Elixir Tip #24 - Erlang phash2 ⚗️ Did you know that you can hash any term in and clamp it to an integer range? In other words, you can get a consistent integer value given any input. Useful for partitioning and retrieving data 😉. #ElixirLang #Erlang #Livebook

An ExUnit on_exit callback runs in another process, so self() inside it is not the test PID. Capture the original PID when cleanup uses it as an ownership key. The test process will already be gone when the callback runs. elixirdrops.net/d/i4LKDQFf #elixir #exunit

👨‍💻 Posted some follow-up observations about phoenix_test performance. #ElixirLang TL;DR: Yes, it can be slower (because it is doing more helpful work), but `async: true` should be your first target if you're having trouble with test wall-clock time -- always. forum.elixirforum.com/t/one-pipe-o...

It never felt good to me to get done working on a change, then be given a list of 20 things the linter demanded I fix before I could ship it. Each of those is mentally taxing, and they really sapped my motivation. When the rewrites happen automatically, it feels like I’ve gotten something for free.

Tyler A. Young ⚗️🧑🏻‍💻 @tylerayoung.com · 10/09/2026

We do *also* have a bunch of linter checks, but they’re for things we can’t fix automatically (where the suggested alternatives are not semantically equivalent). We took the position that anything the linter *can* just fix for you, it should.

TIL the term “dry run” originated with firefighters in the late 1800s; a dry run was a practice without actually turning on the water hose. The opposite term, a “wet run,” was also used.
