Not so much ago, we had a boom of new enterprises offering Massive Online Open Courses (MOOCs for short).

First were Thrun and Norvig (Artificial Intelligence), with Widom (Introduction to Databases) and Ng (Machine Learning). Then, these initial experiments led to the creation of Udacity (founded by Thrun) and Coursera (founded by Ng and Koller).

I have been keeping an eye on them for some time and, in fact, I have been contributing to a project similar to youtube-dl (which I package for Debian), but focused on downloading videos from Cousera, called coursera-dl.

I started contributing to coursera-dl because I wanted to stratch some itches with downloading with aria2c, but soon the original author of the project granted me write permission to the repository and I have been one of the persons that commits the most, which is strange, since I was not the original creator of the program.

So far, from the courses that grant certificates, I have concluded the following:

  • Algorithms: Design and Analysis, Part 1 (Coursera)
  • Machine Learning (Coursera)
  • Introduction to Databases (Coursera)
  • Quantum Mechanics and Quantum Computation (Coursera)
  • Introduction to Cryptography I (Coursera)
  • M101P: MongoDB for Developers (10gen)
  • M102: MongoDB for DBAs (10gen)
  • M101J: MongoDB for Java Developers (10gen)

I have to say that this have been a pleasant experience, with some of the courses being challenging, but not up to what an undergraduate course would be (and the fears of some people that such courses would threaten the conventional University-style model are a bit far at this point).

Anyway, talking about challenging courses, in particular, prof. Umesh Vazirani's "Quantum Mechanics and Quantum Computation" had a lot of (computational) work and this was one of the courses that prompted me to use a computer algebra system for manipulating some tedious calculations.

In particular, I used a mix of the online SAGE math server and Wolfram Alpha, whichever I found the syntax to be easier to use for the problem in question. It is with happiness that I see that there are efforts to get SAGE again packaged in Debian.

Another (positively) surprising course has been Dan Boneh's "Introduction to Cryptography I", which was more theoretical and more serious than what I was expecting. It even included some nice proof sketches and discussion of recent results. The last course on cryptography that I took was in 1998 and a lot of things changed since then, including the way to think about cryptography. But more on that on a future post.

There are some other courses that I may be completing soon and that I will post more about, with some reviews of the good and the bad parts of select ones.
