Patrick,
Welcome aboard!
As for hobbies it really depends on what YOU like. You have mentioned two things already, photography and computer, as I read between the lines. I am also into both as well as an audiophile, the three hobbies keep me busy all the time. Not to mention I also like to share my experience by way of writing on all three subjects, basically ramblings on what I have experienced in the last few decades that I have been involved in them.
If you take up any of the three as your hobby too I will be glad to assit you on the forum. There are others here who also have great amount of knowledge on these subjects and you will come across them from time to time sharing what they know.
Hope you enjoy interacting with all here.
