every once in a while there's a post saying something like "GUIs are better, people only like TUIs because they want to feel cool" then i tell them to do opencode --port=4096 and go to localhost:4096 they can't fathom that you can build both because they can't do either

metaprogramming is so nice. being able to compile out entire sub systems of code based on a feature flag is dope. in jj-startship i have a feature-flag to optionally compile out git support if you are exclusively using jj

while it teaches the science behind prompt caching, @samwhoo's blog post is, imo, the best intro to how LLM's work. filled with Sam's charm, animations, and ability to distill highly technical topics into engaging blog posts, this is well worth your time https://t.co/SyC4ysYRgC

i am convinced that software devs have a speed problem they think the #1 issues is writing code faster... its not. its fixing the code that is already there to stop being utter garbage (as a garbage code connoisseur) quality is really lacking these days, yet quantity has never
