Conrad Irwin @cirw.in · 01/10/2026Just realized that Go’s unconventional capitalization scheme helps them avoid associated methods. func NewFile() *File Hard to get away with that unless your functions and types are in the same namespace 011
Conrad Irwin @cirw.in · 06/09/2026I guess a more interesting question is "what do good compiler diagnostics look like" going forward? Guessing (and hoping) we'll see a shift away from the fancy underlines and colors, and back towards short and succinct 000

Conrad Irwin @cirw.in · 18/06/2026Although agentic coding makes it easier to make large changes; It's so time consuming to keep prompting it to make the small refinements that keep code quality good... Guess that's why they call it a #slopmachine 070

Conrad Irwin @cirw.in · 04/04/2026Fun thing about watching agents write rust is learning new weird features. If you can't put your files in the right place, no problem! 180
Conrad Irwin @cirw.in · 14/02/2026The spicier take is; it feels like all the AI tools I see are catered towards quick-wins and easy fixes. Super dumbed down UIs. I'm really looking forward to tooling designed for the huge wave of expert software engineers that will be here after a few years of practice. 040
Conrad Irwin @cirw.in · 14/02/2026It's really exciting to me how much easier it is for people to get started programming with LLMs. Being able to fully control a computer is super empowering. 130

Conrad Irwin @cirw.in · 14/01/2026Close politely (almost always). If it's something we wanted, and the author makes it clear that (a) they understand what the code is and (b) they chose to create it that way, (and (c) I agree with their judgement), then I'll engage. 120
