I have had lots of other things in mind - university studies, other interests (bowling, floorball and uni activities) and the main reason, some relationship problems that I don't want to share with everybody, and this is why I haven't even felt like continuing it. I have really stressed too much and thus haven't had the interest in hacking either.
But things could turn out different from now on - at least I feel like it :)
Now my studies this year are over and I work in an IT company for the whole summer. So I do have some spare time for hacking too if I get motivated enough to do this. Might as well :)
