2025 was an eventful/disruptive year for computer science research, for two reasons: 1) a shock to federal funding, and 2) the arrival of AI models capable enough to assist mathematical research. 1) is unambiguously bad and 2) is probably mostly good. I'll write about AI first.

Heute ist der Tag des Programmierers. Das ist ein russischer Feiertag am 256. Tag des Jahres. In Jahren, die kein Schaltjahr sind, ist das dann übrigens der 13. September. Warum der 256. Tag? Weil ein Byte (8 Bit) insgesamt 2^8 = 256 verschiedene Werte speichern kann.

@BachmannRudi @jsuedekum @bertpsch Bei einer harten Ansage aus Berlin könnte es doch vielleicht auch die Gefahr geben, dass sich der Landesverband abspaltet?

@ccanonne_ Ah yes, the n log n is of course dominated by the rest. So the surprising thing about cuckoo hashing is only that there is a *hashing-based* quadratic-time algorithm?

[Christian Komusiewicz @chkomus]

@ccanonne_ Did you mean some other running time for the first statement? Like 0(n^2 log n) time?

@BachmannRudi Even if there is causation, the direction is not obvious at all?

@ccanonne_ The reader may ask: is G type 1 or type 2.

@ben_golub and that is it’s impossible to use the word, dynamic, in a pejorative sense. Try thinking of some combination that will possibly give it a pejorative meaning. It’s impossible. Thus, I thought dynamic programming was a good name."

[Christian Komusiewicz @chkomus]

@ben_golub Chat GPT has learned from Richard Bellman, the inventor of dynamic programming: "Let’s take a word that has an absolutely precise meaning, namely dynamic, in the classical physical sense. It also has a very interesting property as an adjective, ...

[Christian Komusiewicz @chkomus]

@ben_golub Hmm, in our field (algorithms) I would say that "since" is used much more often than "because", I never heard of advice against using it.
