💜 A favor to ask: I'm looking to land Elixir consulting work. To help get in front of new faces, I have a "one problem, two weeks, $6,000" offer. Aimed at one nagging thing: a flaky test suite, a stalled upgrade. The debt that falls on the floor. A share or an intro would mean a lot. 🙏 #ElixirLang

Elixir Consulting

Elixir and Phoenix consulting. Fixed-price two-week sprints at $6,000, or ongoing hourly work, for teams that need upgrades, stability, and senior review.

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.
