Second update today...

Well, it's finally time to hit the hay tonight, as it's technically tomorrow, but I figured I'd update once more, seeing as I was so productive today. Whee.

Progress:

• Stanford Programming Abstractions: watched through lecture 12.
• Pointers! Um... are hard. Well, not super hard, but a bit unintuitive. I guess they'll get clearer when I get some practice with them. Hopefully I won't blow up my computer using them.
• MIT Linear Algebra: watched through lecture 9.
• More on spaces; this time talking about basis vectors, vector independence and such. Interesting. Actually this stuff was pretty easy to grasp, at least, at the beginning. Urgh, 9 lectures means I'm due for another problem set. Like Abstractions I guess.
• Coursera Machine Learning: watched through section 5.
• Learning about Octave, which seems cool, I guess. I guess it's like Mathematica, but it's reeeally big on matrices. Haven't really done much with it yet, but it all looked pretty straightforward. We'll see, I suppose.
• Udacity Web Application Engineering: watched through the middle of unit 3.
• Databases! A fairly straightforward topic, at least at the level that it's been taught so far. They aren't exactly lighting my fire as of yet, but I suppose they're cool. The parts that would likely interest me would relate to algorithms. There was a bit of that, mentioning hash tables and the like. I learned a bit of SQL code. With that plus Octave, I can now say that at least in a very limited sense, I've added two languages to my repertoire. Man, including JavaScript and I'm really learning quite a few! Though, none of them I've used in any real depth save for Python and C++.

So yeah, significant progress on four additional courses after my first update! Plus, I talked with my brother for 2 hours on the phone and watched several episodes of Big Bang Theory! Woohoo. Productive day. If I can match it tomorrow it'll be great.

Finding Programming Languages so interesting, I've also registered for the Coursera class on compilers, and watched the first two lectures. I'm not sure how much time/energy I'll be able to devote to that one, but it would be nice if I could complete that one too - perhaps not in a timely fashion though. Oh, and I forgot to mention that I have registered for the GRE! The test date is May 21st... only about two weeks away! Yikes. I keep putting off studying for that, since it's such a waste of intellectual resources compared to the other classes... but indeed, I had better do some more reviewing. Argh.

Stuff I'd like to get done tomorrow: 

• Udacity Robotics course (finish unit 2 and possibly unit 3)
• GRE study
• Linear Algebra and Programming Abstractions problem sets 3 and 4, respectively
• Possibly watch some more lectures on Compilers.
