So far the hardest part of this new AI agent future we're living in is simply keeping track of what all your agents are doing and the multi-tasking involved in keeping them productive, geesh... Makes me think I need an AI agent to help me supervise them all.

I find that Claude Code planning mode is only useful for really small tasks - for larger tasks what's working better for me: Ask Claude to make a plan in a markdown file -- then promptly take that Claude out back and shoot it (ctrl+c) Spin up a new Claude and tell it: "a…

21 years ago today, after months of work, @dhh released Rails v0.5.0 to the world with the note: “this piece will grow in public.” He wasn’t wrong. Since then, Rails has powered countless companies, grew with the support of thousands of contributors, and has kept true to its core…

API Error: 500 {"type":"error","error":{"type":"api_error","message":"Overloaded"}} ugh

Pro Tip for agentic coding: Set rules to use @rails runner and not use rails console for debugging and insights.

"You're absolutely right!" Oh how I hate these three little words. #anthropic #claudecode

Ruby AI Newsletter mentioned at @railsconf! 😍 Thank you @inazarova!

What if we kept our APIs private instead of exposing them publicly? Then wrapped system internals with an MCP server (or equivalent) and expose a single API endpoint that simply accepts a prompt. 🤔

Attending @railsconf and talking to folks, my biggest realization is just how expansive @rails’ usage is, just that it doesn’t get spoken about publicly as often as other frameworks / technologies. Rails just seems to be silently chugging along in many companies’ tech stacks…

There is no reason to use fixtures anymore. They are not faster at all! Well-written factories will be slightly faster. The second file is with factories, and it is 13 seconds faster than using fixtures. So, if you want a fast test suite, you have to choose factories. I hope…
