Every year the grad students host a pumpkin-carving party, and this year a student in my computational physics class contributed a #julialang pumpkin. I'm quite proud 😂

Saddened to hear of the passing of Prof. Axel Becke. What he wrote in this article (pubs.aip.org/aip/jcp/arti..., @aip-publishing.bsky.social) is one of the reasons why I decided to pursue a doctorate in #compchem. Our community lost one of its giants

Very interesting & extensive write-up by @chrisrackauckas.bsky.social on the limitations & benefits of using Claude Code for writing & maintaining libraries for non-trivial / novel computational research (scientific ML, ODEs, etc.) (src: @julialang.org Discourse)
ChrisRackauckas:

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.

> 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 actually worked. And not even for me either. Claude can only solve simple problems that a first year undergrad can do, it can’t do anything more, it’s pretty bad. For people who can use it for more, it’s probably some standard Javascript or Android app that is the 20,000th version of the same thing, and yes it probably is copying code. But by definition most of what we have to do in SciML, especially these days, is a bit more novel on the algorithmic side and so Claude is really bad at trying to get anything right.

The CCL (Computational Chemistry List) will close very soon. I still remember my first post there (as a PhD student, 1998 😱) asking about #DFT and non-dynamic correlation. A big thank to Jan for all this work: having such a resource was important in those dates. #theochem #compchem #quantumchem

🚀 Strong correlation is the Everest of quantum chemistry. Next to the coupled cluster highway, the multireference molecular terrain is underserved—gravel roads and promenades. With Orbformer, we're building a new infrastructure by marrying neural network wavefunctions with cost amortization at scale
