I'm a mathematician at UNAM in Mexico City. I work in algebraic topology, homotopy theory and higher category theory, but am interested in all sorts of math.

I also enjoy computer programming as a hobby and am a big fan of the text editor Emacs.

Several times a fellow chilango¹ has told me they don't like burritos, only for me to learn upon further inquiry, that they have only had them in the US², and then I have to tell them not to knock burritos until they tried them in Chihuahua or Sonora! It seems that here in Mexico City plenty of people don't even know burritos are a normal (and great!) food item in certain parts of Mexico, they think of them as purely a US thing.

(Also, while the average seems pretty bad, you can of course can get good burritos in the US, at least in some parts. I've never had any in the US as that are as good as the ones in Sonora or Chihuahua, but I've had some very good ones in parts of California and New Mexico.)

¹ "Chilango" is the demonym for Mexico City.

² My friends are mostly academics, so most of them have travelled several times to the US.

From a recommendation letter I just read: "Apparently, people like his research and enjoy his talks."

Firefox ESR (is that the Eric S. Raymond edition? —I hope not) often is very slow to recover when my laptop goes to sleep and wakes up. My workaround is to just turn off the computer: thanks to SSD, it boots quickly and Firefox also opens surprisingly fast with all my tabs intact. It takes less time to reboot everything that to wait for Firefox to shake off its torpor.

RE: @rysiek@mstdn.social

It looks like the International Congress of Mathematicians is less serious than the Ig Nobel Prize. 🙁

Nice plot summary... Google just keeps getting dumber.

There is much truth to this post about about #math textbooks.

GIGO (Garbage In Garbage Out) is a core principle of basic computing science, yet we collectively fail to grasp its significance at scale when it comes to generative AI. Those who don't learn from his

@flargh@mastodon.social Charles Babbage on the matter of GIGO: "On two occasions I have been asked, – "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."
