New video lecture: distances, invariants and recursion

I have started a new series of video lectures, which I call “Meyer’s Object-Oriented Classes” (MOOC). The goal is to share insights I have gained over the years on various aspects of programming and software engineering. Many presentations are focused on one area, such as coding, design, analysis, theoretical computer science (even there you find a division between “Theory A”, i.e. complexity, Turing machines and the like, and “Theory B”, i.e. semantics, type theory etc.), software project management, concurrency… I have an interest in all and try to explain connections.

 

The first lecture describes the edit distance (Levenshtein) algorithm, explains its correctness by introducing the loop invariant, expands on that notion, then shows a recursive version, explores the connection with the original version (it’s the invariant), and probes further into another view of recursive computations, leading to the concept of dynamic programming.

The videos are on YouTube and can be accessed from bertrandmeyer.com/levenshtein. (The general page for all lectures is at bertrandmeyer.com/mooc.)

The lecture is recorded in four segments of about 15 minutes each. In the future I will limit myself to 8-10 minutes. In fact I may record this lecture again; for example it would be better if I had a live audience rather than talking to my screen, and in general the recording is somewhat low-tech, but circumstances command. Also, I will correct a few hiccups (at some point in the recording I notice a typo on a slide and fix it on the fly), but the content will remain the same.

Feedback is of course welcome. I hope to record about a lecture a week from now on.

New session of online Agile course starts now

Just about a year ago I posted this announcement about my just released Agile course:

In spite of all the interest in both agile methods and MOOCs (Massive Open Online Courses) there are few courses on agile methods; I know only of some specialized MOOCs focused on a particular language or method.

I produced for EdX, with the help of Marco Piccioni, a new MOOC entitled Agile Software Development. It starts airing today and is supported by exercises and quizzes. The course uses some of the material from my Agile book.

The course is running again! You can find it on EdX here.

Such online courses truly “run”: they are not just canned videos but include exercises and working material on which you can get feedback.

Like the book (“Agile: The Good, the Hype and the Ugly“, Springer), the course is a tutorial on agile methods, presenting an unbiased analysis of their benefits and limits.

New MOOC opens Tuesday

Our online course Computing: Art, Magic, Science, available from EdX, opens this Tuesday (tomorrow, 30 September) at 9 AM Zurich time (and at this time in your area).

An earlier article on this blog described the course, which integrates ten years of experience teaching introductory programming at ETH, and takes advantage of remote-compilation and remote-execution technology from our distributed development research.

You can find the course here.

Concurrency video

Our Concurrency Made Easy project, the result of an ERC Advanced Investigator Grant, is trying to solve the problem of making concurrent programming simple, reliable and effective. It has spurred related efforts, in particular the Roboscoop project applying concurrency to robotics software.

Sebastian Nanz and other members of the CME project at ETH have just produced a video that describes the aims of the project and presents some of the current achievements. The video is available on the CME project page [1] (also directly on YouTube [2]).
