Coursera Course Review: Software Security

I just finished taking the course Software Security from the University of Maryland via Coursera. It was a relatively easy course (at least if you know C) that gave an overview of the following areas: buffer overflows and other memory attacks, web security (including SQL injection, CSRF and XSS), secure design, static analysis, symbolic execution, fuzzing and penetration testing. The instructor, professor Michael Hicks, was one of the more pedagogical lecturers I have listened to, and the whole course was quite enjoyable. Continue reading

Programmer Knowledge

What is the half-life of programmer knowledge? It is quite common with claims that the half-life is something like 5 years. In other words, half of what you know about programming will be obsolete in 5 years. A similar sentiment is: “Programming sucks, because what you knew a few years ago is useless now”.

At first, this seems plausible. After all, there is a steady stream of new programming languages and technologies coming out. However, I think it is wrong. Programming knowledge is much more long-lived than some people realize. Continue reading

Coursera course review: Algorithms: Design and Analysis, Part 2

I recently finished the Coursera course Algorithms: Design and Analysis, Part 2 by Professor Tim Roughgarden of Stanford. I’ve already reviewed part 1, and here are my thoughts on the second part.

The main theme of part 1 was the divide and conquer paradigm. In the second part the main themes were greedy algorithms, dynamic programming and NP-Complete problems. The lectures were excellent, with clear and easy to follow algorithm development and proofs. At six weeks, it was one week longer than part 1, and I found it quite a bit harder than part 1. Here’s more on each part. Continue reading

Coursera course review: Design and Analysis of Algorithms I

I recently finnished the Coursera course Design and Analysis of Algorithms I, given by Professor Tim Roughgarden of Stanford. This was my second on-line course from Coursera (last fall I took Introduction to Databases, which I wrote about here), and I thought it would be interesting to compare  the two.

Introduction to Databases – On-line Learning Done Well

Last weekend I finished the free on-line course Introduction to Databases taught by Professor Jennifer Widom of Standford University. The course was given entirely over the web, with pre-recorded video lectures, and assignments and exams that were automatically graded when submitted. I didn’t quite know what to expect when I signed up for it, but I have to say that it was a great experience. It took quite a bit of work, but I did learn a lot.
