César Yáñez (@caesarcomptus) in the classroom: Process scheduling

I try to have some guests every now and then to my Operating Systems class. The class is not as practical/interactive as I’d like, and having some people show the students how the subjects I teach are reflected in the real world is, I feel, very useful for them to understand the topics’ importance.

The past semester (the first one for me) I had three guests: Chema Serralde, talking about process scheduling and in particular on the importance of real time, from his perspective as a musician, Rolando Cedillo, talking about the early stages of the boot process, and César Yáñez, giving a review of file systems. This semester, there have been two guests so far: Felipe Esquivel, who spoke about parallelism, and used renders with Blender to illustrate the speed gains and limitations (i.e. Amdahl’s law), and this last Thursday, I invited again César Yáñez. César spoke about process scheduling, first giving a quite thorough review of what had taken me at least three sessions to go through, and second, giving some in-depth review based on his experience with Haiku OS.

What else was different this time? I told our coordinator in the faculty, and she invited the other teachers of the subject (and attended herself). So, instead of the usual ~25 students, we have ~40 people in the classroom. And one of them, Adolfo, recorded most of César’s explanation. Yay!

Of course, I asked Adolfo for a copy of his recording, and recoded it in a format more suitable for Web viewing. Here it is (almost 300MB, Ogg Video, ~95 minutes). I still have the original video file given to me, in an Apple-generated badly-compressed .mov, but at over 1.5GB, it’s too much for a Web download. I will try to record future sessions, as they will surely be useful!
