Young graduate students---if you're stuck and having difficulty reading a paper, it can be useful to set that ambition aside, read broadly in the nearby area purely for the sake of general enlightenment, and then approach again in 6mo-1year. The paper doesn't change in the meantime, but you will!

I can't quite believe that we're now announcing the eighth Programming Language Implementation Summer School (PLISS), but we are --- in May next year, if you want to learn more about programming language implementations, this is the place to come!

NSF pares down grant-review process, reducing influence of outside scientists Memo cites overburdened staff, but some say move also aims to elevate White House priorities

Also worth mentioning is the benefit of the reviews for proposal authors. Having more well written reviews helps authors improve and leads to more better science, faster. I can imagine the difficulty of finding qualified panelists, but it's a real opportunity too.

Does anyone else feel the analogy between chatting with an LLM service and looking into a palantir? Like there's the seductive possibility of learning more, but with potential downside of getting sucked in. Also that sentiment of not being sure what's happening with that chat data on the other side.

US students are voting with their feet – and global universities are ready The Trump administration's HE policies are making both domestic students think twice about studying in the US, writes Shaun Carver. Could universities in other parts of the world stand to benefit?

Man. I've always considered America's higher education institutions as one of the major competitive advantages. I sure hope this is wrong.

@shriram.bsky.social , did you once upon a time implement your own hiring portal at Brown using the Racket server library, and used that instead of whatever the institutional platform was? Am I getting my wires crossed?

Ghc now runs in your browser ghc itself can now run purely client-side in the browser, here’s a haskell playground demo. terms and conditions apply, and i’ll write up more detailed explanation some time later, but i thought this ...

This is not a drill: GHC (the #Haskell compiler) now runs in your browser. See the announcement (and please report any bugs) here: discourse.haskell.org/t/ghc-now-ru...

I saw a post that claimed they saw a post, but I couldn't find a citation. The post was:

Every programming language has one of two flaws:

* it has macros
* it doesn't have macros

Your description kinda reminds me of Alvin Cheung &co's work on verified lifting. Is that sort of the right idea?

Oh, interesting thought. My first guess was they originally went with Quadafny , and then a reviewer said it sounded like a former Libyan dictator. So they had to do a last minute s/Quad/Q/g.

Ho. Ly. Smokes. I haven't seen too many tags about #icfpsplash25 over here, but I _gotta_ believe it's because people were too excited and in the moment to be able to stop and microblog about it.

Wowza. What a day. I'm for sure gonna need a double Kopi C to get me going tomorrow morning.
