Sort of global (through an app), but quite unreliable and bound to change without warning

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

Jari Saramäki @jsaramak.bsky.social · Jun 6

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

Jari Saramäki @jsaramak.bsky.social · Jun 6

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.

Jari Saramäki @jsaramak.bsky.social · Jun 6

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

Minut nimitettiin jäseneksi Helsingin yliopiston tiedesäätiön valtuuskuntaan 3-vuotiskaudelle. Tiedesäätiö edistää ja tukee nuorten tieteenharjoittajien tutkimustyötä Helsingin yliopistossa. Olen nimityksestä todella iloinen, sillä tiede ja alma materini merkitsee minulle paljon.

Sama. En tiedä olisiko liikaa toivottu, että kolmesta arvioijasta edes yhdellä olisi edes yksi julkaisu hakemuksen tieteenalalta?

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.

Essay time: AI and science’s happy ending

I’ve been a bit disappointed with the debate about the future use of AI in science. Either it has been short-sighted: “Wow, let’s try this thing we’ve always been doing, but…

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.
