- Reposted by Jari Saramäki4 postdoc positions in complex systems at IFISC, Palma de Mallorca. Call open until 20/10/25, but positions will be filled starting immediately. If interested, please apply now. Candidates must be EU citizens.
- 📢 IFISC (UIB-CSIC) in Mallorca is offering up to 4 postdoctoral positions in complex systems science! 🔍 Topics: social systems, unconventional computing, life & environment. 📅 Deadline: 20/10/2025 🔗 Details: ifisc.uib-csic.es/en/about-ifi...
- 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
- 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.

- 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.

- Reposted by Jari SaramäkiI 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. petterhol.me/2025/02/09/e...
- 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.
- We're organizing a NetSci'25 satellite workshop on Directed Acyclic Graphs — if you're working on, e.g., citation graphs, pedigrees, causality, temporal-network event graphs, network representations of spacetime, or any other areas where DAGs play a role, please contribute! www.dagshop.xyz
