@Nika Bee: Math, my first love. I remember as an undergrad my professor for Calculus encouraging me to switch majors (from Comp-Sci). I had a bad experience in Differential Equations after that with a student-teacher from the Middle-east that led me to stick with comp-sci as a major. Worked out pretty well. I am still working in the field. It was funny in Wroclaw, my son is older than most of the people I worked with. Maybe age discrimination is not as bad in the EU as it is in the US. I doubt I would ever get a job doing c++ programming in the states.
If I had to do it all over, I would probably choose linguistics as a major. Really enjoyed some work I did in Speech Recognition technology.
Regarding windows: some older halls had them. I recall KH in Buolder Colorado that had windows in the lobby overlooking Rockies to the west. I think it must be a liabilty issue.
