CS50x was my first foray into the realm of learning to program almost a year and a half ago. I had been looking at Coursera and edX for several months prior to starting CS50x. A few classes piqued my interest, so I started them, but I quickly lost interest as the lectures were boring or the feedback I was getting wasn't that great.

Enter CS50x - Programming was something I've always been somewhat interested in, but a class I took in high school (using BASIC) and another class I took in undergrad were not very engaging and I didn't make anything interesting. CS50x, on the other hand, is engaging from the get go. You can tell Professor David J. Malan has thought deeply about how to make this class interesting and accessible to people of all stripes. He often pulls volunteers from the class up to his stage to visually demonstrate some of the core principles of computer science. Other times, he plays a short (and entertaining) video clip to get the point across. It also helps that the class has excellent production quality.

This course really shines with it's projects and the various extras it offers. For every lecture, there are several separate videos. First of all, each code example given in class has its own 'Walkthrough' video so you can follow along later. Secondly, many concepts are explained in further detail as part of CS50x's 'Shorts'.

Of course, videos aren't enough to make a course great. There has to be some way to test your knowledge and get feedback. CS50x's Problem Sets do just that, and very well. Each set has a thorough walkthrough, with videos starring the charming teaching assistant Zamyla Chan. Almost all of the sets are done in CS50's Appliance, a virtual machine running Ubuntu, which must be downloaded at the beginning of the course. It makes downloading code and running tests extremely easy, with the added benefit of learning to use a Unix based system for those who are used to Windows.

The first Problem Set uses MIT's Scratch as the programming platform. It allows some creativity, since it's pretty easy to get the hang of. From that point on, however, most of the course is done in C. Starting with some basic algorithms to figure out the amount of change due, the material quickly accelerates, and by Problem Set 3, students are making a version of the classic arcade game Breakout. More advanced sorting and searching algorithms are then tackled in subsequent weeks, before moving on to learning some web development. In the last two Problem Sets, students make web applications using PHP, MySQL, HTML, and CSS. The first is a stock trading application and the second is a mashup of Google Maps and Google News. After that, you are tasked with a final project, using a language of your choice. Unlike all of the Problem Sets, which have automated tests to provide feedback, no feedback is given on the final project by course staff, unless you take a paid version of the course.

The course can be very challenging at times (only about 1% of registrants completed the first iteration of the edX course), and the constant barrage of "This is CS50!" seems a bit too pretentious at times, but overall I found it very rewarding. I feel like I learned so much, and it has started me on a path towards making programming a career. I highly recommend it to anyone looking for an introductory course to computer science.
