OpenGL Tutorial Site
Ok, this is really impressive: NeHe Productions has 48(!) OpenGL tutorials, including instructions for getting OpenGL up and running on Solaris and MacOS X. When you get there, note that if you scroll down to "Resources" in the left-hand column, you can download all the tutorials as a single file.

Handbook of Applied Cryptography
Another reference book available free on the Internet is the Handbook of Applied Cryptography from CRC Press.
