126 buckeyes made. A bit early for holiday cookies, but we've got a new neighbor and their house ain't gonna warm itself!

Oh dear, I just saw an academic paper in which the baseline, described as "naive search," was just querying an LLM...

Woke up this morning to some fresh identity theft! Sucks but glad I caught it early.

FWIW, I don't think my writing from 15 years ago is good either 🫠

"Freedom Foundation" sent a mailer to my teacher wife to ask her to opt out of union dues, implying that the right thing to spend that on is to donate it. Fuuuuuuck them

(As it turns out, the Torment Nexus had already been considerably improved in [Schmidhuber, 1993])

Trying to think of something serious to say about the “cryptographers lose the key for the cryptographer election” story and, mostly, hey: I just love that cryptographers are actually using the weird cryptography! www.nytimes.com/2025/11/21/w...

LLMs will end all disease and double the human lifespan! With all that extra time, and no useful activities left for humans to do, you'll have plenty of time to watch seasons 430-457 of "The Deepfaked Housewives of Datacenter 3f56ea9" on Amazon Prime!

I've published a blog post here, with implementation details and metrics: recursion.wtf/posts/detect/ this may not come as a surprise, but it not spawning a new process via `-exec` for every file or running multiple `xargs` passes makes everything significantly faster

Bicyclic Matrix-Matrix Multiplication in Fully Homomorphic Encryption https://www.jeremykun.com/2025/11/17/bicyclic-matrix-matrix-multiplication-in-fully-homomorphic-encryption/

It's weird how the prefix "cyber" has changed in tone from being cool and cutting edge to lame and cringey

After the twitter shakeup, my social media landscape has settled into: Mastodon for serious math posts Bluesky for jokes / shitposts and politics Lower my personal quality standard for what can go on my blog (and syndicate) And also, post a bit less in general

Why not? People already do "virtue names" (Prudence, Constance, Joy, Mercy, etc). IMO all you really need is a good nickname to go along with it. Chirality ("Kai" for short) Idempotence ("Ida") Correspondence ("Correy") Symmetry ("Sym") Theorem ("Theo") Geometry ("Geo") Tessellation ("Tess")

I feel like this is the end of the golden era for salacious emails. Corps and individuals are already starting to crack down and auto-delete emails after a certain period of time.

These elites and world leaders write their little emails like I wrote my AIM chats in the 90's. g2g crime l8r?

Just saw a newspaper delivery car drive by and it had some sort of rail gun launching papers onto people's porches.

ok wtf is Alma Linux and why the hell does cibuildwheel force me to use it.

The Zelda movie had better be about the balance of nature and Mononoke/Nausicaa type shit. If it's another lame cash grab like the Mario movie I'm going to be very salty about it.

Sine, wasine, secant, wasecant, tangent, and watangent.

FIFO (first in first out) and LIFO (last in first out) queues are so CS 102. Today let's talk about the FAFO queue (fuck around find out).

Hi, I’m Alex goldman. I used to host a podcast called Reply All that some people liked. For the past year I have been making a show called @hyperfixedpod.bsky.social. We now have 25 episodes (50 if you count premium episodes). You might enjoy it! Listen if you liked reply all

It's the calm before the Halloween storm in my neighborhood

Mastodon came through, gotta up your game mathsky 😘

Look at me I'm posting an image from another social network like a basic bitch. But THAT social network has typesetting 😀 and so the post reads nicer than if I retyped it here with no typesetting.

I agree that STEM, the social sciences, humanities and all the rest need to stand together against anti-intellectualism. I am also aware that when humanities funding was being collapsed, there was not a lot of STEM solidarity and there are STEM folks *now* still suggesting under-bussing humanities.

Not being an AI-doomer, but having experienced in my own department over the past 7 years a steady erosion of faculty governance norms and diminished prioritization of research-oriented pedagogy, this tracks. Let faculty and faculty interests lead the way, rather than administrators/regents

NGL I love this part of train trips. Get a sleeper car, dine with a rando, have a conversation with someone out of the ordinary.

There should be a bsky filter for "accounts that only post pictures with overlaid political messages"

😍😍😍😍

The wealthy are not moving away, and everyone is getting free childcare.

But also, just make it a fucking website! If the app is designed in a half decent manner, this should be easy.

Every time someone posts about how inconsistent some Republican talking point is, I want to shout, "THEY DON'T CARE" Pointing out hypocrisy doesn't achieve anything, and just allows them to control the discussion and distract from what matters. Ignore it and reframe.

I liked my Google home mini, until bit by bit it got worse at its core function (set a fucking timer) and now it's a brick. Can't imagine buying a new one based off Gemini, because what's to stop that one from becoming another brick?

An LLM that talks about itself like Chris Farley when it makes a mistake "I'm such an IDIOT"

Is it me, or does "copy/paste" just suck on computers these days?

It's like Minecraft for rigorous thought. It's a souls-like for your brain. It's a rogue-lite for your eraser!

I'll be giving a talk called "Lessons from Software on Managing Complexity", starts in 45 minutes.

Honest question: why don't people make and share email blocklists, and build up some basic automation around adding to them and syncing them? Surely people like this are few but noisy, and people could preempt voluminous email harassment quite easily.

Software books I wish I could read: buttondown.com/hillelwayne/... Write more books, people!

@anyaustin.bsky.social I heard about you recently and I think your videos are pretty cool. Keep it up!

Just a reminder to check for your name in this list of books that OpenAI trained from. If your name is there, they probably owe you several thousand dollars. OpenAI cried that if everyone eligible author files, the company will go bankrupt, so I'm alerting every author I have ever spoken to.

Good article, largely saying similar to others but saying it well (better than I can)

Our first featured presentation at the code4math.org Grand Opening will be featuring houseofgraphs.org — a database of *interesting* graphs, featuring metadata and search to help researchers in the field. Join us 9am Eastern on September 8! preview.scholarlattice.org/collections/...

Having ordered custom Lego pieces myself, this is fine. So many local options. Better to reduce waste and disincentivize buying so much shit online (fast fashion, etc.)

rebellious conference room sticker "become unbookable" send post

May this portion of the dissent by Ketanji Brown Jackson haunt John Roberts forever and be the final word on his tenure as Chief Justice.

Oh yeah I posted a new newsletter for the first time in a while. It's short but maybe people like that. Who knows, I don't do analytics on it. buttondown.com/j2kun/archiv...

Nightmare. Can't sleep. Post away!!!
