[nycbug-talk] Darwin Kernel Hacking

[Isaac Levy]

Hi All,

Thought it was worth forking a new thread here, seeing as Mach Kernel  
hacking has gotten a WEE bit off the topic of file protocols... :)

Ok, so here goes some urls about kernel hacking in Darwin/OSX, and may  
shed some light on why Mach is different from other BSD kernels.
(note- I'm not at all suggesting any kind of kernel argument here, but  
am simply interested in sharing differences, strengths/weaknesses...)   
Any folks here with BSD Kernel Hacking experience, who just recently  
purchased iBooks etc..., (cough cough), here's some urls:

And noteworthy, while stumbling over Google fast to see if I could find  
some relevant Non-Apple source material, I found this nugget of fun:

Mach and Darwin binary compatiblity for  NetBSD/powerpc and NetBSD/i386.

(Photoshop on NetBSD/i386? wtf? perverse...)
