From mathcurve.com: Alain’s curve (studied by Alain Juhel) is the projection of the intersection of the elliptical cone c²z²=a²x²-b²y² with the hyperbolic paraboloid cz=x²-y² onto the xy plane: So it makes sense to plot that xy projection as 0-level contour… Continue Reading →
In September, Ulrike, Joseph, and I attended PDF Days in Berlin to present our work on making complex STEM documents truly accessible. The core message: PDF/UA-1 simply isn’t designed for mathematics, so marking documents as “compliant” doesn’t mean they’re actually… Continue Reading →
The final pre-release version for the 2025-11-01 LaTeX kernel went to CTAN few days ago: it’s now in TeX Live, and we hope people will test it out. As with previous recent releases, the major focus here is tagging: we… Continue Reading →

As I mentioned yesterday on goLaTeX.de, the forum mrunix.de was permanently closed on August 1, 2025. The reasons were low activity and a high volume of spam. Besides Unix topics, the LaTeX subforum was very active—probably the most active of… Continue Reading →
Wie ich gestern auf goLaTeX.de erwähnte, wurde das Forum mrunix.de am 1. August 2025 dauerhaft geschlossen. Grund war die geringe Aktivität und das hohe Spam-Aufkommen. Neben Unix-Themen war das LaTeX-Unterforum sehr aktiv, ich würde sogar sagen, am aktivsten von allen… Continue Reading →

This is a demonstration of how to write Japanese text in TikZ pictures, using luatexja.
またXの夜。@nawi0718の質問を見かけて、「はい、TikZで絵が描けるよ」って答えられるなーと思って。ヘッダーに朝比奈みくるがいたから、さっとこの絵を描いてみたよ。彼女の恥ずかしがり屋で控えめな性格が好き。
