Windows is for gaming, GNU/Linux for everything else. I rarely play games, so most of my time I use GNU/Linux. I'm not very advanced admin, but I know how to use Google. My current distribution is Antergos.
I was always interested in taking photos. Few months ago I bought a DSLR and now I enjoy photographing more and more. Especially I like macro, urbex and experimental photography.
Android is my love, but love without root privileges is not interesting. Custom ROM is something, what is necessary for my life, because I love experimenting.
