Listening to My Students at Scale: Exit Tickets, NotebookLM, and the Tightest Feedback Loop I've Ever Built It started at a teaching workshop, last semester: Craig Kapp and Rob Egan presented a seminar at the NYU Center for Teaching and Learning ...

Panos Ipeirotis (NYU): "How I started using exit tickets (short feedback surveys after every class) and processing them through NotebookLM to generate follow-up materials before the next session. The feedback loop went from one semester to a few hours." www.behind-the-enemy-lines.com/2026/02/list...

Bluesky Network Analyzer Find accounts that you don't follow (yet) but are followed by lots of accounts that you do follow.

There is a third-party app for this, you can find it here: bsky-follow-finder.theo.io

My impression with bluesky is that a lot of things exist but there is just no way of finding them.

Jenseits fester Pole: Was Netzwerke ΓΌber Polarisierung verraten Forschende der TU Wien entwickeln ein Modell, das Meinungen nicht als diametral entgegensetzte Pole interpretiert, sondern als ΓΌberlappende Bereiche auf Gruppenebene.

Meinungen und Einstellungen sind selten schwarz-weiß. Ein Forschungsteam der TU Wien zeigt, dass sich Positionen in gesellschaftlichen Debatten oft ΓΌberschneiden und nicht klaren Lagern zuordnen lassen. Das neue Modell analysiert dafΓΌr Interaktionen zwischen Gruppen. πŸ’¬πŸ“Š

I enjoyed reading this. I agree that throughout the last 10 years or so, CS has become a lot more empirical.

This also means that there is a lot of work for theoretical computer scientists out there.

The directed next-to-shortest path problem was solved by 2 undergrads! arxiv.org/abs/2511.04345 Look out for Kuowen Chen and Yiran Zhang this PhD application cycle.
