IT, linux, opensource movement, free software, software development, network security, voip and so on. Modern technology in general. Travelling. Politics (have to, every conscious human being should). Women (have to, every male human being should). Cooking (japanese & italian cousine). Loads of other stuff.
My future wife. And her lovers, too.
Electrionic music, mainly progressive house/trance, but also house, trance, electro (house), minimal, breaks, ambient and others.
Requiem for a dream, Boston Saints, Lost Highway, Human Traffic, Oldboy. Polish: Mis, Sexmisja, Kingsajz, Dlug. Lots of others that I forgot the names of.
Mostly hate it.
Rarely read anything not being displayed on my computer's screen, although somewhere I have some list of the books (do I?) that I want to read someday.
Rambo, Terminator, Conan. You name it. Seriously though, everyone who is happy with his life. Nothing more to it.
