It looks like NS is down. @NS_online, without warning or explanation, Delft Station has had no regular trains running since at least 0530 this morning. The digital displays show a message error or nothing at all and just now a high-speed freight train passed unexpectedly by.

Go, @Max33Verstappen! Two hours, two championships!!!

Interesting analysis of an interesting report. A detailed bibliometric analysis across leading research cities (and regions) in Europe. Lots of insight.

My IEEE GeCon 2022 keynote "Social Gamification Works! Empowering Students for 21st-Century Higher Education" is available online: https://t.co/GDk3Brq6ds Many thanks to @LargeResearch, all collaborators. #social #gamification #21stcenturyskills #education #highereducation

ICPE 2023 will be held in Coimbra, Portugal, in April 2023. Important information about the conference is already available on the website: https://t.co/s6T4bLqqck #ICPE2023 #ICPEconf

Our first book! Not yet done, in fact still far from that, hence the (analog) design gear. But it's our first and we are very enthusiastic. Thanks, @LargeResearch, @rellermeyer, all collaborators!

Congratulations, @avandeursen, @alanhanjalic, team @EEMCS_TUD! Thumbs up also for transparency.

On best practice for sharing research software. Thanks, @danielskatz!

Dear all, thank you for your kind birthday wishes and thoughts. Unfortunately, I've been down with COVID-19. After three rounds of vaccination, during two years of patience, my first. There were difficult days, but now I'm well. Good time to smile now. Stay healthy.
