I often have people ask how I’m using Claude code so much, given that I have a bot account storming the SciML Open Source Software repositories with tens to hundreds of PRs a day, with many of them successful. Then GSoC students come in with Claude/Codex and spit out things that are clearly just bot spam, and many people ask, what is different? The difference is actually knowing the codebase and the domains. It turns out that if you know how to actually program, you can use the LLM-based interfaces as just an accelerator for some of the tedious work that you have to do. I tend to think about it the same as working with a grad student: you need to give sufficient information for it to work, and if you don’t get good stuff back it’s … READ MORE

Claude Code sucks but is still useful: experiences maintaining Julia’s SciML scientific computing infrastructure
So it’s pretty public that for about a month now I’ve had 32 processes setup on one of the 64 core 128gb RAM servers to just ssh in, tmux to a window, and tell it to slam on some things non-stop. And it has been really successful!… with the right definition of success. Let me explain.
This is a repost of the long post in the Julia Discourse.
* How is Claude being used, and how useful has it been?

I think the first will answer the others. Basically, Claude is really not smart at all. There is no extensive algorithm implementation that has come from AI. I know some GSoCers and SciML Small Grants applicants have used AI (many without disclosure) but no wholesale usage has … READ MORE
