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

If you're already at @netsciconf.bsky.social and you're wondering what that graph is doing on your badge, here's the reason! We will have a lightning talk on wednesday to explain the rules before the first coffee break, don't miss it!

Hi dagshop.xyz participants: the entrance is through Grote Gracht 90 (no-one knew this until a few minutes ago). We are on the ground floor left from the entrance (there is no sign) @netsci2025

New paper out! "A Blue Start: A large-scale pairwise and higher-order social network dataset" in collaboration with @cetaceanneeded.bsky.social, Ilya Amburg, @diesagar.bsky.social, and @foucaultwelles.bsky.social. Paper at arxiv.org/abs/2505.11608 and dataset at socialmediaarchive.org/record/78

DAGshop is almost here — less than a week to go! If you’re at NetSci, come explore the connections between temporal networks, causality, spacetime, quantum gravity, and more. dagshop.xyz

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.

Registration is now open for IceLab Camp – a four-day off-site PhD course designed to train participants in asking research questions, laying the foundation for new multidisciplinary collaborations. www.umu.se/en/icelab/ca...

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.

In other news, here is some new music with me producing and playing bass: music.youtube.com/playlist?lis...

The deadline for applying to our PhD position in GeoAI & LLMs approaches soon! Apply by next Sunday 2nd March to our exciting PhD position! 🌐 💡 See more details below.

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. 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

Here's a quick recap of the NetSci 2025 speakers announced so far: @lindadouw.bsky.social, @jsaramak.bsky.social, @zdeborova.bsky.social, Iza Romanowska, Sonia Kefi, Michael Macy, @manlius.bsky.social, Huijuan Wang. #NetSci2025

My LaTeX compiler duly and understandably complained about the \textbff{} command I entered, and now I am wondering whether I've accidentally invented some new term for computational social scientists working on smartphone ego-nets

The worst thing about writing grant applications is that they make you think about all the great stuff you could be working on if you wouldn’t need to write grant applications

📢 NetSci 2025 Speaker announcement: Jari Saramäki, Full Professor at the Department of Computer Science, Aalto University "Networks in Time and Space" #NetSci2025 @jsaramak.bsky.social

New paper in PNAS 📰🚨 Beyond a binary theorizing of prosociality www.pnas.org/doi/full/10....

#NetSci is one of the most #awesome true #multidisciplinary conferences in existence. If your research deals with #complex #networks, and you are not part of the crowd yet, please consider submitting & participating. "All is Interaction" – A. v. Humboldt netsci2025.github.io/calls/ Please repost!

Here is a @github.com repo where I will share tutorial notebooks on how to retrieve and analyze data from @bsky.app @atproto.com Feedback, suggestions, and contributions are welcome! github.com/brianckeegan...

So many new people here, brilliant!! Complexity people interested in art meets science — here's some music to start your week with, composed using temporal networks of baboon interactions from the SocioPatterns project: jarisaramaki.fi/2024/09/30/b...

🚨 ALERT 🚨 Are you looking for (recent) longitudinal social media data? We recently released a huge #bluesky anonymized #dataset of social interactions and contents covering 80% of the service users for 13 months. Available on Zenodo! Read more: arxiv.org/abs/2404.18984 #academicsky #NetSci

A starter pack for researchers interested in #ComplexSystems. Complex system science investigates how interactions among multiple parts lead to collective behaviour, as well as how the system interacts and forms links with its environment - please add your name! go.bsky.app/FNYZ61y

Nice to see Bluesky finally taking off! Hello all new followers! For those interested in scientific writing, here are some blog posts: jarisaramaki.fi/tag/scientif...

Haluaisin vaihtaa sen neropatin kanssa pari sanaa, jonka mielestä on hyvä idea, että yliopiston Outlook-sähköpostijärjestelmä herjaa koko ajan huutomerkillä ja punaisella, että lähettäjä/vastaanottaja on organisaatiosi ulkopuolelta. Jotain on tässä ymmärretty pahasti väärin.

I interviewed @jsaramak.bsky.social on his journey in #network_science. We discussed how to formulate impactful research questions, the importance of collaboration, and his advice for younger researchers. youtu.be/HwdZS6Fy8X8

When I open my next postdoc call, I will attach these photos of April weather in Finland. Limits the pool of applicants to extremely motivated people. Or insane people, come to think of it…

Whaat, (at least some) OpenReview conference reviews now require a title (!) for the review and a brief summary, and then the review itself. Having to come up with titles is a bit much... Here is my complete set of alternatives: "Great paper", "This is crap", "ChatGPT generated this title"
