Entertaining June

Scroll for English

Keine hochfliegenden Gedanken für heute. Bloß zwei Juni-Musikstücke vor und nach dem Englischtext, die ich seit eh‘ und je liebe, und der Link zu einer Konferenz, in der ich die aristotelische Sau rauslasse.

Enough with scrolling

No big philosophy for today. Just two songs that pertain to June and that I’ve loved for years and years, and a link to a conference in which I’ll have an Aristotelian agenda to defend.

Last debt to a dead friend

Scroll for English

Gerade eben korrigierte ich Hansens Beitrag in UNILOG 2013 in Rio de Janeiro fertig. Die Kongressakten mit dem wenig bescheidenen aber akkuraten Titel: The Aftermath of the Logical Paradise, hg. von Béziau et al., werden bald erwartet.

Hans wollte noch vor der Publikation des logischen Paradieses lieber schnell das himmlische Paradies erleben.

Enough with scrolling

I just finished the proof-reading of Hans’s contribution in UNILOG 2013 in Rio de Janeiro. The Aftermath of the Logical Paradise, ed. by Béziau et al., is expected to be shortly published and to give a picture of the event.

Hans, unfortunately if you ask me, preferred to see the heavenly paradise before the logical one.

TeX and rust

Scroll for English

Nach Jahren der Pause arbeite ich wieder mit TeX. Ich kämme Hans Burkhardts Text aus Jean-Yves Béziaus Universallogik-Kongress in Rio de Janeiro. Ein letzter Dienst an den toten Freund.

Nun, es ist unglaublich, wie schnell ich verrostete. Ich gucke die ganze Zeit nach! „Hmmm, wie war jetzt noch mal die TeX-Syntax dazu?“

Enough with scrolling

Years after, I’m working with TeX again. Just proofreading Hans Burkhardt’s paper from Jean-Yves Béziau’s Universal-Logic congress in Rio de Janeiro. A last service to the friend who passed away.

And it’s ridiculous how fast I got rusty. I have to check for the syntax of TeX features I had been using constantly.
