Hello, My name is Jasenko Krejić, I live in the beautiful town of Banjaluka, Bosnia, and Herzegovina. After wrapping up my master in telecommunications, I have been working with computer systems. A decade ago, I had my first encounter with Linux and immediately fell in love with it because of it being an open-source! I work in an enterprise-level company, but I always try to stay ahead and do various other projects, and learn new technologies. Part of learning is sharing knowledge. I consider it a part of my learning path. I hope that in my articles, I have aggregated my knowledge, explained the material as simple as possible and that I have sparked your curiosity to learn Linux.
