My first time going to the Outer Banks in North Carolina. It was surprisingly warm and sunny over the weekend. (Timeline cleanse?)

This paper has been gaining lots of attention... I've seen it on my LinkedIn and Facebook feeds now (in addition to several times on here) www.reddit.com/r/LocalLLaMA... news.ycombinator.com/item?id=4575...

This is worth a read regardless of your stance on or professional incentives to promote or oppose AI:

The path to a superhuman AI mathematician. (Mathematics is the first place where evidence of AI superintelligence is likely to appear, a theoretical computer scientist says). ~ Lawrence Fisher. cacm.acm.org/news/the-pat... #AI #Math #ITP #LeanProver

Soumith Chintala, creator of PyTorch, leaves Meta: soumith.ch/blog/2025-11... I had the privilege of being on a relatively small call with him while I was at FAIR. Seemed like a really humble person.

uwu what’s this

Today on the job I learned about the cpulimit and taskset commands. They limit CPU utilization of processes (but in different ways)

> Turnout surged past two million voters, the highest level of participation in one of the city’s municipal elections since 1969. About tonight’s election in New York City.

ChatGPT recommends PyAV as an alternative to cv2 for reading through frames in a video. Chat, is this actually a reasonable alternative? #python

A movie you’ve seen more than seven times with a gif.

Echoing what’s said in this thread. Idea seems interesting and worth trying out. I have no intuition for how this’d go in practice.

Uh, does Spotify *really* need a DM feature?

Alright. After hearing so much from friends about It Takes Two, we’re gonna give the game a shot.

I don’t know how I’ve gone this far in life without knowing what the phrase “what’s the tea” means or really hearing of it. Relevant XKCD: xkcd.com/1053/

If I’d had the time this year to plan for a Halloween costume (I *almost* did it), I would have revived my Todd Chavez (from Bojack Horseman) costume. Really easy homemade outfit.

I read ArgoCD as “arg, OCD” and won’t be able to unread or unhear that ever again

Florence + the Machine’s new Halloween-themed, spooky album is out! spotify.link/Kk6rMK4FUXb

Found it on my second search. (incidentally @mackuba.eu it would be incredibly helpful if the search tool indexed the embed data and not just the post text - this didn't show up in a search for "arxiv")

I got to see a really cool demo of an aerosol jet printer (it prints electronics stuff) today and it’s a reminder to me of how much interesting, non-AI technology there is out there. I always enjoy learning random new things from non-CS, non-AI STEM folks

Random things you only learn when writing course material: jupyter will not color hyperlinks that are on back ticked text (code), so it isn’t obvious that it is a hyperlink. You have to mouse over to see that it’s hyperlinked because then you’ll see it underlined when you do

(Reposting this only to pin it) I’ll be presenting at the Joint Math Meetings this January! I’ll be talking about distributed computability to an audience of applied category theorists. meetings.ams.org/math/jmm2026... Results presented are originally from my PhD dissertation.

god I will never get over how sensitive to coffee I’ve apparently become

@nsaphra.bsky.social, I just realized that our last names are permutations of one another (my display name is intentionally misspelled right now, because, you know, spooky month; it’s Saraph if not obvious) I don’t think I’ve ever seen or noticed any other such name.

Uh, as much as I love all the fake internet points I’m getting on this post, go actually donate to PSF!

I donated $25 to the Python Software Foundation. Did I do that to post about it social media? Yes. Did I also do it because I think that the Python programming language is awesome, and PSF and PyCon are awesome, and they need more funding? Also yes.

I obviously know that LLMs are not great at doing arithmetic (like adding two numbers) (use a tool call instead!) but for Qwen you have to use surprisingly large numbers before it fails at correctly adding them. Like 50 digits large.

My team at Quantinuum is looking for a Lead/Principal Quantum Compiler Engineer to join us. You'll be at the forefront of quantum tech, developing the compiler infrastructure that translates quantum algorithms into instructions for our cutting-edge trapped-ion quantum computers.

In all my years writing Python code I don't know how it is that I never came across the bisect module: docs.python.org/3/library/bi...

> Our central finding is that causal decoder-only Transformer language models are injective almost surely. I don't read enough ML theory papers like this. Very interesting results here. As part of the injectivity proof, it's shown that transformers are also real analytic.

Geometry and topology have some of the weirdest counterexamples

Reminded yet again today that BNF syntax is itself expressible in BNF.

Okay. I caved and got Pokémon Z-A.

It’s very cool that there’s a whole microkernel (seL4) that’s been formally verified: www.sigops.org/s/conference... en.wikipedia.org/wiki/L4_micr...

Aaaand session 2 kicks off 🔫 🐎

I wrote about SAT solvers: vaibhavsagar.com/blog/2025/10...

It’s exciting to say that I’ve now actually written some Lean code for a work project leanprover-community.github.io

I first heard this banger of a song on Never Have I Ever and was glad to once again hear it on the last episode of Ginny and Georgia: spotify.link/dWdHEfyKBXb

Just finished teaching session 1 of an AI course 😮‍💨 my co-instructor and I have gotten a lot of positive feedback but it’s also been an excellent learning experience on how to teach.

I came across this seemingly informative stack exchange post as I begin to scratch the surface of PL-y and formal methodsy thing: langdev.stackexchange.com/questions/26...

I see a lot of discussion among my mutuals about a supposed influx of new users on here? What’s up?

Welcome new AFOLs and other LEGO Fans check out the LEGO Feed and give it a heart to help other newbies find it

Prompt engineering? It goes without saying that all engineering should be completed in a timely fashion.

I don’t know how today is the first day I heard this joke, but a friend just texted it to me today: > Are you today’s date? > Because you’re 10/10 🤣

I somewhat recently learned that Lean is also a functional programming language in addition to an interactive proof assistant and now I know which language I’m going to try advent of code in this year. (hint: it’ll be Lean)

The pre-hunt to the MIT Mystery Hunt, which this year is being called MIT Mystery Hatch, will be starting in just a couple days online and is open to the general public! It ran a few days ago for MIT teams only. www.mitmysteryhatch.com

Apparently I login to Bluesky to learn how big the moon was.
