It's probably because they are both complex systems of unknown origin and nature... When put in such way, all nonlinear complex systems seem to display some disturbingly similar traits to each other, regardless of the nature and scale of the components and the system itself.

If I was you I'd have different .bashrc files for different linux, unix, bsd versions. Yeah that is definetly something to keep track of.

I tend to use it for short commands that are annoying to type in (ls -laF... anyone), but make sure they're compatible with each system I use. There's nothing worse than getting used to a do-it-all alias called psgrep (ps aux | grep $1) which returns different/incorrect results on an older BSD/Unix system. That isn't a very good example mind you :P I've got the defaults from an old Gentoo system that I carry around with me in a .bashrc file now. That being: alias ls="ls -la" alias mv="mv -vg" alias cp="cp -vg" Apart from that I'll usually try to keep it short and sweet, and use the other commands to their fullest. I must admit, after continuously typing some, so many times it becomes second nature to actually keep typeing them. So much so that I'm then thrown as to how to solve the problem when I want a different behavour. For instance, without thinking, I'll see a tar file (usually with a bz2 extension) and type "tar -xjvf", only to come accrosss a .gz file and and have to think for a second as to correct command for gz files, which mind you is actually easier and more intuitve than the bzip command itself.

This has bitten me more often than I care to admit! I wrote lots of automation code in C, then we started implementing different things in C++ for a VRML front-end (this was in the late 90's). It took me quite a while to determine that the rule of thumb is to keep the type (and pointers and references count) in the first stage of a variable declaration. It's not a stupid mistake; it's a common thing for people coming from an ANSI C background. With C++, you’ve got to remember to put your types at the beginning of a definition.

I'm going to enjoy these for a while... As for the Make magazine boards, I'm fascinated with the idea of putting some of those together in an oddly-shaped board instead of a clean grid. Unfortunately, these boards are still a little pricey per unit given that a single glider might take up the majority of a single board. Again, excellent find! Excellent find!

But it's one of those things I'd like to find out how to do but all I know about computers right now is some linux, c and c++. I haven't been able to find much about doing it using playstation 2s. They are really cheap right now and they have the same linux compatibility. I’m not sure how they did it besides the fact that they used the graphics card.
