Sometimes you can find yourself in a situation where you need to compare two sets of data in your shell script. Until now I was unaware that rms is a co-author of the program does just that. The utility is called comm and you can probably find it in your distro’s core packages.

Sometimes we have to use Matlab at work. Whenever that’s required, it brings pain for various reasons. My team managed to solve one of them for ourselves and other coworkers. Let’s start by describing where the issue comes from.

I started my first job a month ago. Until now I didn’t care about managing my configs because I had a single workstation.

The only missing point was a mechanism to use them in a managable way since now they were kept in a separate place.
