I often daydream about some physics thing, or how you can things make things in principle. Also (embarasingly) i sometimes daydream of being, well, sort-of-rambo. (nah different really, but a hero basically.)
I also think about darwinbots(.com) sometimes, like making a worm-bot. (I tried a little, cant get the tie-connections to work, although the manner of communication is simple as can be :/) Or about all kinds of things that can be programmed in principle, but i never get to actually program them. There is too much of those idea's for one, and although the principles of working in my head often work. (even programmed them) I often miss that i need other principles too, and also I never seem able to put them together.
I hope my luck with common lisp is better then with c++. I actually started to dislike the classes of C++, calling things member functions seems silly to me now, unless it is really only gaining simple information from a class. (sure, in a member, it saves writing, but note lisps '(with-slots (..)..)' )
Lately, this forum is in my head often too.
