Music on Console aka MOC is perhaps the most lightweight and easy-to-install music player for Linux I have ever tested. And don't be intimidated by the fact that MOC is a console only player. Once you spend enough time with MOC, it becomes as easy to use as any other alternative music players for Linux. Moreover, if you're a fan of MPD plus NCMPC combination who doesn't like to jump through hoops just for installing and setting it up, MOC might be the alternative you have been looking for. It's right there in Ubuntu repositories by default.
The latest bi-weekly Wine development release is now available and it brings with it some noteworthy changes.
MATLAB  has to be one of the all time greats for analyzing nearly any sort of data, just like a spreadsheet is for making a plot of data. Alas, these programs while powerful do have a limitation – they are costly and rightly so: They do a job, have great depth and are actively supported, and we all know that this takes some overhead dollars to maintain. For spreadsheets we have some really well done GNU options like Libre Office. But what about our design programs?
The GNU design software tends to be somewhat usable but unpolished in many cases; the same could be said about the many MATLAB-like GNU options. This one does that well, that one is a little different there, etc., but none of them "Hits a home run" on all counts, until now.
GNU Octave  is the closest MATLAB-compatible program, with all the same language syntax, etc. In fact many basic MATLAB scripts will run without an issue in Octave. The biggest thing that held Octave back was the command line interface.
