Recently found out about @jvkersch.bsky.social's `tmtools` github.com/jvkersch/tmt.... It works nicely! Being able to pass user-defined sequence alignments is a nice (if simple) feature that is missing from OpenStructure's own `tmtools` @torstenschwede.bsky.social.

Experiment 2 with #claudecode: vibe-coded #manim animations to convey the intuition behind QQ plots, which are notoriously difficult to explain just on the whiteboard.

First impressions with Claude Code: Add section headers to my calculus slide decks, and have autogenerated ToCs (github.com/ugent-korea/...). Overall: productive experience, but weird -- the jagged edge is real. 🧵👇

Dropping one "Make it so, Mr Crusher" has made Claude Code switch completely into Star Fleet officer mode...

The figure quoted in the article is 3Wh per query, which checks out: running one query with the DeepSeek 70b model quantized to 4 bits keeps my GPU busy for about 30 seconds, which works out to 1-1.5 Wh.

Plus or minus sexy?

Casually leafing through Leibniz's papers, as one does, and was surprised to see these astronomical symbols ☽☉ used as shorthand. Looking forward to using these, as well as ☿♃♆ etc in my calculus class.

This reminds me of my own journey to Python way back when (about 20 years ago). I was in a B&B without internet access and couldn't access the Matlab license server, and just decided to ditch it altogether.

Started reading Paul Nahin's "An Imaginary Tale: The Story of √-1" in preparation for teaching about complex numbers. Somehow I had never seen the derivation of the formula for the roots of a cubic, and was surprised at how easy it was to follow -- and how magical it must have been to derive.

Recently I got a citation alert for a paper that extended a result of mine from 2010. Upon closer inspection it turns out that the authors are from North Korea. Crazy that we are a mere 250 kilometers apart but we may be as well on a different planet.

Today I had to simulate a bioinformatics pipeline running in limited resources. Some useful commands, available on any modern Linux system 👇

New rule to survive the dark Belgian winters: hours before sunrise and after sunset are dedicated to learning.
