A little bit more than 2 weeks from the beginning of the semester I have an idea what are the courses going to be and what I’ll be doing during the semester. In my Economics course there is this old professor that “is teaching this course for 35 years” and since the beginning of the semester we’ve been watching videos of “Economic USA”. Pretty boring. In assembly language, we write programs like

3. ; Your program will then print either twice the number or 9, whichever is larger."

In Environment the only topic is how bad humans are and how because of us the planet is in such a bad shape and there are so many illnesses around.
My last course, independent study - “Spectrum Analysis of Network Traffic” ( Sounds pretty cool ) I haven’t done much about. I’ve only read some big portion of the book Fourier Series by Georgi Tolstov. I didn’t do much more, because I had to finish my other Independent study - Networking. Fortunately the paper is almost finished. It just needs some polishing and it is done.
