My search for books only led to extremely out-of-date publications, and the whole ordeal was generally frustrating. I was amazed at the lack of documentation. Even Motorola and IBM's documentation resources (on the web) were lacking anything of use to me. However, it turns out that Apple provides a pretty good free tutorial on the subject. It's tailored for coding in Mac OS X, but I imagine it would be just as useful in any PowerPC environment. For some reason it includes instructions for the Intel architecture. Perhaps this has to do with the fact that Darwin runs on x86 as well."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
