OpenAI PrismのLaTeXで日本語を使う

とりあえずOpenAIのPrismのLaTeXで日本語を使う方法をまとめておいた: okumuralab.org/~okumura/mis...
ほかにノウハウがあれば教えてください。

Typst is used to create the official Swift reference. Check the repo for a great example on how to create long-form documentation with Typst.

Fix uneven CJK-Latin spacing in justified paragraphs by ryuryu-ymj · Pull Request #7606 · typst/typst Fixes #6062 This PR ensures that CJK-Latin spacing is applied evenly both before and after Latin glyphs when par is justified. Previously, Latin glyphs followed by CJK characters were not marked as...

Typst使えねーと思っていたCJKのアンバランスがfixされたようだ github.com/typst/typst/... 次のリリースで直るんだろう

Blueskyの新しいガイドライン、否定的反応が多いですね。

1. Safety Firstの D.Adult Content、やC. Child Safety、でフィクショナルなもの、イラストやアニメなどにまで規制の強化が強いあたりとか。

The suspensions landed perhaps most heavily in math. NSF suspended a $25 million grant for the Institute for Pure and Applied Mathematics (IPAM), an international center at UCLA that hosts about 2000 visiting researchers every year for workshops and other programs. One of its stars, Terence Tao, a Fields Medal winner frequently named as one of the greatest living mathematicians, also had his only NSF grant suspended. The $750,000 award was in its first year and supported Tao’s own research and a handful of graduate students in developing tools to tell whether a set of numbers is structured or random. Tao says he now cannot offer research assistant opportunities during the academic year, and he calls the cuts to IPAM “quite disastrous.”

Tao’s ultimate goal is to use the tools to solve the twin primes conjecture, a centuries-old problem in number theory that suggests there are an infinite number of prime pairs that differ by two, like five and seven. But the NSF grant provided the vast majority of outside support for his UCLA salary. “I’m currently doing summer research unfunded,” he says.

Math at UCLA suffered the greatest blow.

I spoke with Terry Tao—Fields Medalist and arguably the preeminent mathematician of his generation—who is apparently now doing his summer research in number theory without external funding.
