Professor Plödereder was (is?) in the ISO standardizing committee for Ada and it shows.

Great professor, great lectures. I took every lecture he offered.

My best memory is when he asked me questions in an oral exam that weren't totally foreign, but... somehow off the expected path. He never asked many questions whose answers were right in the lecture notes, always probing whether you had understood the concepts, so I assumed he was particularly demanding that day. When I came back into the room to get my grade, he told me that his TA had informed him that he was examining a different lecture than he was supposed to, and that he was quite impressed how I held myself up. The grade was accordingly chosen. :-)
