High performers tend to be ones who constantly re-evaulate their process (i.e. "how" they work) and keep on improving it.

Everyone should listen to what Addy has to say about AI coding.
Very thoughtful and level-headed but yet very optimistic about AI.

Just donated to PSF.
Sad to see they had to withdraw their proposal to the US government but I think it's the right decision.
My donations small but just wanted show some people are behind them.

Been posting the same message to X, Bluesky, Threads, Mastodon. Some apps retry properly even in the background.
You can always resend it yourself but it's so much more pleasant to use.

Simple grep commands prefered over RAG for code search and uses smaller models for 50% of operations.

Feels like it's becoming increasingly important to have "good taste" of what's better for your codebase.
It used to be that you had to spend time on code edits before you could tell but with LLMs like Claude Code, it's way easier to try it out.

Apple's new on-device LLM is post-trained on a special data structure that is and to be generated by the developer based on a Swift Generable annotation.
This is interesting.
First time I've seen an LLM integrated with a programming language in this way.

I'm starting to think static typing (or rather stricter rules enforced by the compiler) is the way to go when it comes to AI tools (Cursor, Cline, Claude Code, etc).
The compiler can pretty much direct the AI agent to apply the changes needed.

Wow...Claude Code has just upgraded my GitHub helper command written in Haskell from 9.10.1 to 9.12.1 and actually used it to create the pull request merely by reading the code (and maybe the help message it executed during the session).

The Composable annotation must be convenient.
But these "implicit" injections of code makes me wonder whether it might be impeding new comers from understanding how things actually work.
