Compared to this trip, that sonification is far too orderly and organized. The beginning was more Zappa than Kraftwerk

It did, but the shortest path required 4 trains instead of 2: trains just dropped passengers at random Dutch stations on the way and told us to wait for the next one

Solution: my cognitive limits prevent me from taking a route involving 4 German regional trains and computing alternatives should any or those connections fail -> waiting for the shortest path to materialize.

Time-respecting path problem: getting by train to Düsseldorf. Your first train is cancelled. Should you wait for a direct connection (to be cancelled with probability p) or pick a route with many hops (p again per hop, but increasing number of alternatives). There must be a DAG for this #NetSci2025

Something got broken in my coding setup (several things were deprecated) and I had to ask ChatGPT for help. I complained to it that I feel old, and got this as the answer: "That’s not 'old' — that’s veteran-level :-)" This will be my new motto I think.

I channeled my inner Marvin Minsky to give a different perspective on AI science. It ended up being about how our lazy attitude toward our language stops science from its (utopian-level) full potential … and stuff.

Yes, and sometimes it’s good to let your subconsciousness do the work. Maybe I’ll write more about this on some occasion. But at least to me, the best ideas (including RQs and hypotheses) come when I am not actively looking for them. Reading books is slow, and slow is good!

How to choose a research question?
Choosing which problems to work on is perhaps the hardest and most crucial part of science. It is also an invisible and underrated part.
