Trying something new. I’m turning my two-track agents article into an animated explainer video. Writing a script, syncing with images, animations... It's hard! 😱 Hope to share the result soon.

It’s hard to collaborate with Claude Code on writing. Too much copy/paste. I wanted something like Google Docs for the agentic. So, I used Tidewave to build a local Markdown editor where I can connect Claude Code and we can work together. Would you use this?

Tidewave is the first AI tooling pitch in a while that sounds like it understands the actual job: not just reading code, but running it, querying data, and checking logs. If it works as advertised, that’s a meaningful step up from autocomplete with branding.

I use LLMs to audit my code a few times a week now. Below is the prompt I use most often. It's super simple, runs in less than 30min on a medium codebase, and gives you actionable suggestions for how to improve performance, data integrity, or security in your codebase. #ElixirLang

I'm building {insert purpose of your application}.
I want you to do an adverserial review of the codebase
Please run one subagent per file and per focus (performance/security/integrity).
Write your findings to `docs/audit/(performance|security|integrity).md`.
Give each finding a unique identifier in its header.

I'm using @ash-hq.org for the first time and I believe their tagline should be: *Ridiculously powerful* The amount of heavy-lifting they do is absolutely bonkers. All the stuff you don't *want* to care about in a web app is just being taken care of. *Massive* kudos to everyone involved!

Bye bye Claude Code 👋 We had a great time. But it's time to move to Codex. I want to be free to choose the harness that works best for me while paying for my agent provider subscription.

I was able to wire up Popcorn to run Elixir and PGlite to run Postgres, both in the browser. This means we can have an interactive and safe sandbox for arbitrary code. Which means a really good experience learning Ecto on a website. I'll publish it soon :) #ElixirLang
