does any have the tenderbutton/dylan stiles archive in one place? #chemsky #chemchat There's a lot mirrored on archive.org but it would be great to have it fast, searchable and ideally complete somewhere

sad to see the low success rates of MSCA this year, with many excellently rated projects not meeting the unusually high funding threshold. wonder if the big increase in applications is due to the decline of american science funding and prestige

sometimes, you simply require thousands of unique SMILES for the same molecule (e.g. teaching a language model to pretend it's a graph based model instead). A prototype of the trivial "solution" to this problem using disconnected atoms dialect of SMILES is here now: github.com/dehaenw/ultr...
