Computer Knowledge CD v2.0

I was just going through and rebuilding my Computer Knowledge CD, and I ran out of ideas of what to put on it. I have about 50 megs left to fill. Anyone have any ideas?

The main topics right now are Assembly, C/C++, Internet/Hacking/Security, Networking, Mathematics, Windows, Cisco, and Misc.

Any and all ideas are appreciated. Thanks in advance.

What does this CD contain? Tutorials or Programz? Or both?

Tutorials and books. Use to have programs, but I cut those to make space for the text.

Well. . . I suggest you add the Digital VooDoo Tutorial to your cd. Its pretty good.
