“oh boy have I got a toy for you asta.allen.ai/discover”

Joshua Grochow: Can one do "algebraic geometry" over a monoid in place of the coordinate ring? That is, suppose I have a commutative monoid. Is there a coherent (in the informal sense) notion of Zariski topology? …
Joshua Grochow: (Answers would be great, but I'm more looking even for keywords, authors, etc to look up - hard to search for.)

Ted Underwood: The Internet era is kind of rough on faculty in emerging fields, because if University U hasn’t yet hired someone in your field, the students there *will write you* to ask sincere, interesting ques…
Ted Underwood: I guess my takeaway is not, students pls be less curious & proactive — but more hurry the f up, Univ U.

Berna Devezer: i cannot wrap my head around that 2 papers a week (socarxiv) or a month (arxiv) should constitute a meaningful cap on preprint submissions. 2 papers a year (no one) though? that i'd get.
David Marx: They probably picked that threshold based on the current percentiles to try to at least "desk reject" the worst offenders. powerlaw effect as usual: it's likely a minority of bad actors are committ…

Mark Riedl: Reporter: OpenAI is a true champion of equity and democratization, with new results on low-resource languages… hold on, I’m getting an update… *holds finger to ear* COBOL. They mean COBOL.
David Picard: They're listening to their highest paying tier consumers who are mostly... *checks notes*... boomers??

Sung Kim: You'll be surprised how many unexpected bugs and inconsistencies this approach uncovers, even when your existing tests pass. Make sure the agent verifies expected results and application state chan…
Sung Kim: One effective approach is to have your AI coding agent create an API using the OpenAPI standard, generate an SDK, and then use that SDK to perform black box testing against the running app.

Eric Brachmann: It appears that coding agents have been trained on too many SOTA chasing papers, because they latch onto tiny, meaningless improvements in metrics. That's what you get...
David Marx: maybe try adding a prompt indicating a research phase, like "We are early in design exploration. There is a lot of uncaptured value to be leveraged. Don't get caught up on small incremental improve…
