A screenshot of the DBLP page for the journal "Discrete Mathematics". The page lists volumes published by year. Between 2006 and 2013, and between 2015 and 2026, one volume was published per year. In 2014, for some reason, 23 volumes were published.

Learning that 2014 was apparently a huge year for discrete mathematicians, for some reason.

The hardest part of writing a new paper isn't figuring out all of the main ideas in your head and how to prove them, it's having to figure out all of the 'infrastructure' (background, motivation, definitions, references) you need to include to support those main ideas.

4-panel SMBC comic update. A woman is teaching a man sitting at a desk. The man says "I get it! You write (equation)* and that tells you the superposition is some amount in the 0 direction and some amount in the 1 direction." The woman replies "now that you've got it, we'll use this easier form" and proceeds to write a much longer equation on the board. The man then says "this is why people become chemists" to which the teacher replies "do not use the c-word in my presence" *equation won't copy properly in the alt-text.

Sadly, it appears Michael Rabin passed away on April 14. Among other achievements, Rabin received the Turing Award with Dana Scott in 1976 for their paper "Finite Automata and Their Decision Problems", a highly influential work in automata theory.

I've never taken an economics course in my life. The extent of my economics knowledge is a second-hand textbook left behind when an undergrad friend moved out for the summer, currently 2000km away in my mom's basement. And I can still say with confidence: I know more about economics than this guy.

30 years ago today, Principal Skinner purchased fast food to disguise as his own cooking at an unforgettable luncheon with Superintendent Chalmers.

With all the news today about Hungary, my mind keeps going back to one thing: lángos is one of the most delicious foods I've ever eaten. I've been to Hungary twice and that's not nearly enough to get my lángos fix.

A screenshot of an assignment question I wrote. It reads: "In the Astadhyayi, Panini developed a grammar for the Sanskrit language. Here, we will use the grammar for a very small subset of Sanskrit. Consider the following four Sanskrit root words: bhu (to be), kr (to do), path (to read), likh (to write), and vad (to speak). Sanskrit combines root words with endings that depend on the grammatical person and number: - First person singular: ami - First person plural: amah - Second person singular: asi - Second person plural: tha - Third person singular: ti - Third person plural: anti For example, to say "I read" in Sanskrit, you would say pathami. Like Panini, we can develop some grammar rules to form Sanskrit words: - word -> stem ending - stem -> root a - a a -> a (sandhi vowel contraction rule) - bhu -> a (guna vowel gradation rule) - kr a -> kara (guna vowel gradation rule) Using our grammar rules, how can we derive the following words? (a) pathami ("I read", first person singular) (b) likhamah ("we write", first person plural) (c) vadasi ("you speak", second person singular) (d) karatha ("you [all] do", second person plural) (e) bhavanti ("they are", third person plural)"

One of my favourite parts of teaching TCS is motivating concepts in a way that goes beyond just the definitions. When we cover grammars, I mention Pāṇini and his work on Sanskrit. Today, I wrote this fun little question.

Can anyone familiar with Sanskrit tell me if I made any embarrassing mistakes?

A screenshot of an ad from Best Buy Canada. The first product shown in the ad carousel is an anatomical model of a “mammary gland in lactation” from Walter Products. It looks exactly like what you think it is.

Either Best Buy is really diversifying their product offerings, or I’ve done something very strange to whatever recommendation algorithm served up this ad.

Earthset captured through the Orion spacecraft window at 6:41 p.m. EDT, April 6, 2026, during the Artemis II crew’s flyby of the Moon. A muted blue Earth with bright white clouds sets behind the cratered lunar surface. The dark portion of Earth is experiencing nighttime. On Earth’s day side, swirling clouds are visible over the Australia and Oceania region. In the foreground, Ohm crater has terraced edges and a flat floor interrupted by central peaks. Central peaks form in complex craters when the lunar surface, liquefied on impact, splashes upwards during the crater’s formation. [alt text from NASA]

HISTORY MADE!
Orion Integrity and its Crew Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen have broken the 56 year old recod set by Apollo 13 and its crew James Lovell, Jack Swigert, and Fred Haise, and have become the humans that have travelled the farthest distance from Earth.

Okay everyone, Artemis II is behind the moon. We've got about 30 minutes now to replace everyone in Mission Control with apes to make the crew think something happened while they were away.

Cross Country Canada is the greatest trucking simulator that ever existed.

You didn’t grow up a Canadian millennial if you didn’t experience the pain of being towed because a pebble hit your windshield.

Good paragraph

i'm sorry but the moon is a complete boondoggle that should never have been put up there in the first place. we still have to send repair missions up there a hundred-plus years later all because taft was trailing in the polls and decided to learn magick. i don't know why he thought it would help him

I can't believe this is all building up to the biggest April Fools' reveal of all time: that the moon is fake and they're just going up there to change the bulb in the big spotlight.

I have a similar feeling when writers (notoriously, most academic writers) describe something as “celebrated”. Of course I know “the celebrated result of so-and-so”, everybody in our field does!

A Twitter thread posted by Aalok Thakkar (@AalokDThakkar) on Mar. 22, 2026. The tweets read, in order: 1. "While there is a dearth of women in computer science, another problem is that the women who are in CS often become invisible. I’ve been teaching Theory of Computation and have comfortably used photos of Turing, Church, and even problematic figures like Minsky and Chomsky." 2. "Only today did I learn that Greibach, of Greibach Normal Form, is a woman. Sheila Adele Greibach is an Emeritus Professor at the UCLA and has worked extensively on contex-free and context-sensitive languages, parsing, automata, and decidability problems." 3. "There are so many excellent women in computer science doing foundational and groundbreaking work. I hope we (I) get better at naming their work, showing their photos, and telling their stories when we teach. This visibility shapes who feels like they belong."

This is something I've had to contend with in my own courses. I regularly tell students about Greibach (grammars), Goldwasser (zero-knowledge proofs), and Williams (matrix multiplication), but so many results in the core curriculum stem from the same group of guys and I don't know how to improve it.

I watched The Godfather for the very first time last night. And I suspect when I share this news with my friend group, they're going to react in exactly the same way as when I told them I first watched The Sound of Music just a couple of years ago.
