Once again, on March 11 I had a great guest to save me some work and give a talk at my class! This time it was César Yáñez, and he talked about memory management algorithms, emphasizing on ARC.

The video is available, both at this server and in archive.org.

Thanks a lot!

Another guest in the classroom! Sandino Araico ( @KBrown ): Memory management and security

Submitted by gwolf on Sun, 11/03/2013 - 12:16

This last Thursday I was able again to lure a good friend of mine into presenting an interesting topic to my students at my Operating Systems class: Sandino Araico, a very well known and very well regarded local security guru, presented several issues regarding memory management. I asked him to present the issues on buffer overflows, as well as possible mitigaion strategies, but of course, to present that topic, he had to walk all over the map of memory management.

A good and interesting class. I was able to film it again, and here it is — Sadly, as I explain to some students who suggested me to put the computer in a different place, the angle and the audio quality are not as good as they could — If I were to move the computer to have a better angle of Sandino, I would lose audio quality.

Being it the eve of Día de Muertos, and having a beutiful mega-altars festival just outside the faculty, the outside noise level was quite high, and... Well, I know Sandino rarely raises his voice, so it was better to locate the computer close to him. Of course, add to it that my hardware is by a long shot far from professional-grade. I just used a very cheapish laptop.

I was a bit skeptical to begin with — I have to recognize I have given this topic quite hastily, as we are getting near the end of semester and there's still a lot of topics to cover. But the students seemed interested in Sandino's presentation, and –once again– I am fully satisfied with my guest's performance.

As always. All of my six guests' presentations (over two semesters) have been great. If I were able to get a guest for each of my classes... I'd even save a lot of class-preparation time! :-}

Oh, but you came here looking for the video, right? Here it is: Memory management and security, by Sandino Araico. October 31, 2013.
