Any academics I follow interested in moving to Europe? My department here in Maastricht, Netherlands, is hiring:

Associate Professor in System and Network Security, open until May 10, 2026
https://vacancies.maastrichtuniversity.nl/job/Maastricht-Associate-Professor-in-System-and-Network-Security/1357701057/

Assistant Professor in Computer Systems, open until May 10, 2026
https://vacancies.maastrichtuniversity.nl/job/Maastricht-Assistant-Professor-in-Computer-Systems/1357700157/

Both of these are for the equivalent of tenure-track, i.e. after a 18-month probationary period, you have a permanent contract.

I'm happy to tell anyone interested about the university, the department, the role, the city of Maastricht, or about moving to the Netherlands as an English-speaker.

Et tu, Grüne?

Even the German Greens are supporting the fairytale of a 'highly efficient' combustion engine, alongside 'climate-friendly fuels', plug-in hybrids, hydrogen and e-fuels.

With these friends, the European Green Deal doesn't need enemies.

This is from the planned coalition in Baden-Württemberg

I made mini onigiri for bike ride fuel. And I was dead chuffed.

Thanks Oheso for the suggestion many moons ago here in Bikenite

@ascentale @bikenite A8: rode round Wollongong yesterday. Some very nice coastal bike paths, and then this approach into the city proper from there.

It's both impressively well done, and a reminder of how hard it is to retrofit good bike infrastructure into a car-dependent hellscape. It's not ideal to have a shared path down a hill, but finding space for car storage, car movement, bike movement *and* pedestrians?
