On the MSc I was participating in, there is a teacher that has a lesson about Databases.

The MSc was not only for experience computer science students. We were informed that the first semester would be as an introduction to all.

So, Databases. No introduction at all. Just read the powerpoint and the pdf he had just translated (or not, because some were just from the internet), just refers to how they are structured briefly. He showed everything about Databases without the students that didn't know much to be involved (we didn't get to our lab for some reason) and then there was his assignment.

His assignment was written as it would be from a customer that knows shit about Databases (sorry but I had to rant). We sat down student's that knew already Databases and some of us worked as database engineers. We agreed on some steps that after read the next chapter of the assignment we reconfigured them. And so on, until we had nothing and we were back at the beginning.

Needless to say, I did not lose my Christmas holidays for him. It took me 2 days after to build a database that was not a full solution but a part (I wad noy sure, the assignment was ambiguous). I passed the lesson with the minimum passable grade.

So, I wrote a nice email to the MSc teacher that had to organize it (or something like that). I did not swear at all. I was professional and wrote what I encountered and what it should have been. The Databases teacher had always that smirk and face that he was THE boss and had no respect for his own lesson. But I didn't mention it. The organizing teacher shared the email with the databases teacher.

And the time came that we had another lesson (web development, it was awful under him) with the databases teacher. And he had the wonderful idea to read the email out loud in front if everyone. He did noy mention my name. I raised my hand and told my colleagues it was me. Then I asked him in front of them, if he was contented with the results (only a few passed the databases lesson and max grade was the smallest passable), first he avoided the question. I asked again. And he said yes. We all looked at each other and somehow knew. No one spoke and I didn't push because I didn't want to take the web lesson's hours for this. It was just hopeless.

From there on, the teachers said we were their best class ever but the most complaining one. They didn't even bother to analyze the "complaints".

So, there you go. One of the lot of those teachers.
