Posted on 2024-06-19 by Oliver

… and her infamous line “Fuck the EU”. Why? Because tomorrow the decision will be made whether the EU introduces surveillance for what’s meant to be private communication. Originally the voting was supposed to be done today (2024-06-19). More information … Continue reading →

Why?

Posted on 2024-04-12 by Oliver

I have written about Microsoft Teams before (in German), how horrible a user experience it is and so on. Let me tell you, it hasn’t gotten any better. Only “newer”. Remember, Microsoft loves Linux now. Right? Or so people, including … Continue reading →

Posted on 2023-10-27 by Oliver

Previously the so-called Office and especially Teams were ranking quite high among the shittiest software from Microsoft in my book. In fact Teams in all its incarnations is probably going to take up the four rear slots in my top … Continue reading →

Posted on 2023-07-10 by Oliver
