An interesting side effect of using coding agents is that my GitHub Issues have become much more detailed. Mostly as context to the agents when they plan. But I've benefited from that so much already, both in easier context switching between tasks and better onboarding for new contributors.

I love that we're discussing the use of .unwrap() in #Rust today, but I'm wondering how actionable the discussion is for most maintainers? I've found designing good error types one of the hardest challenges in API design.

Okay, fell down a rabbit hole. In positive news, refactoring the module for my GitHub org and manually manipulating the state to migrate resources has worked!
There's something about #Terraform that just tickles my brain in the right way...

Fuck all of those "Try Gemini" pop ups when I try to get work done. Why can't Google just remember that I wasn't interested in Gemini yesterday and I am still not interested in it today...

Wondering what the right time is to start a glossary for internal company lingo. The company is two people and a Notion doc, so I guess we're too late?

I'm trying out GitHub's Spec Kit with Claude Code today and I have so many questions. Feels like something is missing in the toolkit that enables small units of change while still allowing the AI to drive the design. Will report back later...

Two weeks in, countless brainstorming sessions later. We might've accidentally founded a brainstorming consultancy instead of a company. 🙈

I want to start writing shorter, more frequent blog posts. Long-form takes too much effort and social media's too brief to explore ideas properly. I want something in between - a quick way to explore unfinished ideas.
Should probably just start, right?

Funny how if you ask AI to critique something it just generated, it'll tear it apart about 90% of the time. Zero loyalty to its own ideas. 😂

Just made a sprint planning meeting notes template. Haven't had to do that in... years? Not sure if that's a good or bad sign.
