[mkc2023] No lecture next week

Hi everyone,

like already said yesterday, there will be no lecture next week (April 13th), because I'm on vacation. The next lecture will be on April 20th.

Sorry also for the bad BBB experience yesterday. No idea why we were thrown out multiple times. BBB worked really well last year actually. Let's hope it's better next time.

Best regards and happy easter, Nils
