Uses 0's and 1's to make things happen. AND contrary to popular reports, 
0's and 1's have NOT (yet) been patented by B. Gates.

see the fiddlybits in  /usr/src/linux/*

See above answer.

Again, see above the previous answer.

ext2, reiserfs, fat32, fat, and just about any flle system, with a few hits 
or misses.


As secure as you make it.

huh?, is this anything related to DQ? oh, it's been a warm day..

>Networking facilities

ouuuu, this gets complicated...

>User interface(s) supported

too many to remember. Mainly (for me, anyway) kde, gnome, window maker, 
icewm, blackbox
and heh, ncurses.
oh, and fvm or something at times of immediate stress.

You can inspect, change any and all the code that you can find. There's 
lots of tid bits and mentions in the kernel source. Have a nagging opening 
screen? You can nuke it from where it really counts: the source code.
Oh, did I mention, its free? Built by (mostly) volunteers. Although these 
days, I'd hope they got some kind of compensation other than stock.

can't help ya there, either. Good luck

Right now, I'm using SuSE. and trying to get tascam 428 action going on for 
linux. So far, the kernel has yet to have a usb midi class... Someone that 
needs it, has a lack of hardware.


sure- anytime.
