Why LiveView DOM patching doesn't overwrite attributes updated through JS commands? This is one of the top questions I received after my "mastering live view reconnects" talk.
I finally have time to explain it 😁

Finally spent some time trying to contribute to Expert LSP.
I started to have problems with Expet with Zed and asdf.
With the inspiration from this gist.github.com/jeregrine/1b... and some help from Claude Code, I was able to try some improvements:

Elixir is full of useful gems. Just came across this one to capture logger outputs scoped to the test. Doing something like that in the Tuist CLI codebase took us a bunch of boilerplaity code:

Want to disable all unmocked HTTP calls from Req at once during #ElixirLang tests?
Simply add this to test/test_helper.exs:
Req.default_options(
adapter: fn req ->
raise "Unmocked call to #{req.url}"
end
)
(replace `raise` with a log warning if that's more useful)

Most coding agents wait for you to bring them the error.
Tidewave catches the exception in your running app and asks: "fix this?"
You don't have to explain what went wrong because it's already watching your app, not just reading static files.
Here's how it works.
