It is with immense pleasure that @KathiFisler, Ben Lerner, @joepolitz, and I announce the first version of our new book, DCIC: a Data-Centric Introduction to Computing. This brief thread explains the book a little. 1/10 https://t.co/3OT5hOLHsE

Oh good! Someone from the @racketlang community can weigh in on the benefits. Oh wait… Anyway, sooner or later the time for computable reals will come. I'm still HODLing stock in continued fractions (and teaching them every year to my first-year students).

I am sharing one of each of these adorable desk mats. If you want to be considered simply let me know which one you would like! 🎁

Realizing that I live in a city with lots of artists and hence proper art stores. Going to go try one of those for a proper ball-point.

Lost ball-point pen. Went to Staples to get a new one and felt depressed. Remembered I had this old box of fountain pens my dad had given. Decided to revive one of them, impractical as it is. So the Sheaffer inlaid nib it is for now, for the ~10-15 words/month I write by hand…

Now available by popular demand.

To be clear, I'm not involved in this in any way. I'm just messaging for a mutual and because this looks cool.

Planning out a UK tour ~ mid-Feb/mid-March 2026. Stopping by U's of Edinburgh, Glasgow, Oxford, Cambridge, King's London, Imperial (say hi if you're at these places!). Anything else going on in that timeframe that I should know about, before I finalize plans?

Popped into a store to get a beer to go with tonight's Game 7, and this seemed rather appropriate given the dramatis personae…

From reporting about last night's World Series Game 6: This is the kind of amazing act that makes someone a professional. Not only the sensory ability but also the ability to act on it in a fraction of a second. And it completely changed the game's outcome.

🚨BREAKING: Colorado Online Censorship Label Law HALTED in NetChoice Lawsuit DENVER–Today, a U.S. District Court granted NetChoice’s request to temporarily halt Colorado’s censorship law that would have compelled online businesses to display government-mandated "warning"

Very unusual to see Australia get Australia'ed, that too by India. What a gripping pair of semi-finals in the women's ODI world cup! Just hope the final doesn't prove to be a damp squib. #cricket

What can a German studies and gender studies professor have to say about tech and thinking? Quite a bit! Well-written and insightful, with a bit of SV "inside baseball" thrown in. The quotes at the bottom of this page are surprisingly accurate. #BookReview https://t.co/BhnSJL1Oar

One of the most remarkable episodes of @theanalyst Inside Cricket is this one from 2020 of "The special sounds of cricket", featuring commentator Dean du Plessis, who is BLIND. Even by the amazing standards of visually impaired people, he's next-level. https://t.co/tk3EP270rK

This is the end-point of extractive AI. First get people to upload everything, then suck everything out of it, then get AI to generate all the answers. I wonder how this cycle continues. (If it means Chegg can't continue the cycle…paint me so sad.)

Icarus International Consulting Group | The War on Buttons: A Human Rebellion Against Unnecessary Complexity Some wars are fought over land, others over ideology. Ours, today, is over buttons—and it’s a battle that touches the core of what it means to be human in a digital age.

Me: You're from Toronto, right? Student: Yeah! M: Is there joy in Mudville? S: ?!? M: That's a baseball reference! S: Oh, I hate baseball. I have a whole list. [We spent 15min on it. Mostly fair; some even map to cricket. Some were just wrong!] Education takes many forms! 🙂

Gotta watch *the episode* in her honor tonight. https://t.co/7CeJQwB0Fe

It's forbidden to play this game on the Singapore subway. [Game designer says "we designed a fast-paced, educational game that teaches players to differentiate durian types while maintaining the original's chaotic fun". https://t.co/ovVInHRymQ ]

Was discussing w/ friends how I think Mamdani would perform as mayor. I was curious to see what prediction markets had to say. Surprised that only Kalshi had any on post-election acts; Polymarket and Manifold only on election itself. (I don't really use them; is this typical?)

"All maps are wrong, some maps are useful." Mostly this just traces colonialism. Reduces countries to one language. Turkish used an Arabic script until the Atatürk Latinization reforms. Etc, etc.

This is a banger of a fact!
