Some web pages (e.g. reddit) aggregate a lot of useful youtube links, but provide no way of playing them all, without adding them manually in a playlist.

That is where my next little project comes in. You give it an URL, it looks for all the URLs that look like they point to a youtube video, generates a list and a video player that will automatically play them all.

Usage is very simple:

Currently there is a limit of 120 videos, imposed by the youtube API.

Berlin: been there, loved it, and returned. Now just a 3 day version and with a quartet!


For simulations I need to call functions in MATLAB and retrieve results from within a omnet++ simulation. There is documentation, however, it took me a while before I got it all working. So, I ended up with a small wrapper class that allows one to evaluate MATLAB code in a running MATLAB instance.

Because MATLAB has to start up the GUI every time the simulation starts (edit: I discovered it has a flag -nojvm -nodisplay -nodesktop which speeds this up), it gets quite slow and annoying, and thus I also looked at writing a wrapper for octave, a language that is largely compatible with MATLAB. Another advantage of using octave, instead of MATLAB is that octave is a shared library that runs in the same process, so one can pass around pointers.

By flipping a switch, the code will be either MATLAB or octave based.

The source and very simple, small examples can be found in source.tgz (5 KiB, modified on 27 January 2016, MD5 0b00489725ee2afbd929429f004c2355)

The Settle Up app is pretty useful; it lets you share bills quite easily with groups of people. It's pretty good, except for the fact it has no web interface, and thus useless for people without a smartphone (or tablet) at hand. I and a group of friends had to settle up a visit to Amsterdam, and my fingers itched to quickly jot a webpage, where you could just easily view and edit the data, and also have a set of transactions (not guaranteed to be the minimal set though).

You can try it out at, or even see a working, nerdy example Source is available at
