where can the newest code of darwin for ppc be found?
Either on Apple's Darwin Developer site (<http://

does a website exist? or do all coders only send the sourcecode
back to apple? and apple will then release newer versions?
I have no idea what you mean here.
i'm asking because i'm not satisfied with the speed of osx...i
think it's the mach kernel which is quite slow...do newer, i.e
faster versions optimized for example for the g5 exist?
Well, look at it this way: Apple ships one version of Mac OS X that
works on all systems (well, currently, per CPU architecture). The
Darwin source represents a small chunk of the system, measured by
lines of code or by bytes used on-disk. Even if you shrunk the the
Mach kernel to size zero and decreased the kernel cycles needed to
execute whatever is asked of it to zero, this would probably account
for a 5-10% speedup[*].
Most of Mac OS X is *not* open source.
