Our Military, the greatest and most powerful (by far!) anywhere in the World, hasn’t even started destroying what’s left in Iran. Bridges next, then Electric Power Plants! New Regime leadership knows what has to be done, and has to be done, FAST! President DONALD J.TRUMP

Trump is committing war crimes in Iran and is threatening more and worse ones. His entire war strategy at this point is war crimes. A functional Congress would be far down the road of impeachment and removal.

This Palm Sunday, let’s remember...

Jesus chose a donkey of peace instead of a horse of war.

Jesus disarmed his followers instead of forming an army.

Jesus exposed the evil of violence instead of partnering with it.

Jesus laid down his own life instead of taking anyone else’s.

Add VacuousTest check · s3cur3/credo@7e502a5 This adds a new check to flag tests that fail to exercise any production code. Broadly speaking, these are tests that amount to either - testing the test itself, or - asserting that the Elixir lan...

Wanna find garbage tests in your #ElixirLang codebase?

I'm working on a Credo check that will flag any test that fails to exercise production code. Stuff like:

test "to_string works" do
assert to_string(:user) == "user"
end

(That's a real example I found in our ~20k test codebase!)

#ElixirLang 🤝 #Typescript like never before 😎 This is *end-to-end type safe Phoenix channels*. The typescript client is *generated for you*. This is on top of a full RPC generated from your actions. Works with any typescript front-end. This is *huge*.

With pi-agent, I use a todos extension, originally by @mitsuhiko.at, that makes it super easy to interactively steer the agent; I use it for the same type of reasons. Though, an out of band todo, as is the one you create, could be much easier to reason about, think through, and type out.

The more I have AI agents write all my code, the more I feel that us devs will be alright (and possibly more in-demand for important stuff)

Hard for me to imagine anyone building *reliable* software without an understanding of how to do this (either via experience or study)

We will somehow escape to some deserted island that has a forgotten/hidden cache of rum left over by Captain Jack Sparrow. I can’t think of any other way to survive the absolute incompetence and foolishness of every single member of this administration and their “decisions”.

For all TUI enjoyers, if you haven't tried gh-dash.dev, you're missing something. It's a simple gh cli extension but it feels like giving GitHub a proper tiling window manager.

Simple but so good.

Very Important Agents | Nick Nisi My recent Changelog and Friends podcast appearance and the Claude Code plugins that help me get real work done with AI.

🤖 Very Important Agents

I was recently on the @changelog.com & Friends show to discuss my AI workflow, AI browsers, Bun's acquisition, and more! I wrote about it and went into more detail on my workflow plus some of the agents I'm building/using.
