Optimizing Software Occlusion Culling – index | The ryg blog edit / delete
Detailed worked example of optimising low-level graphics code. AG0803 students, you'll probably like this (well, if you like AG0803).

Software optimization resources. C++ and assembly. Windows, Linux, BSD, Mac OS X edit / delete
Good stuff -- lots of information on how modern computer architectures work. (I'm upgrading my previous assessment of this site, having found it really useful while updating the CE0813 material!)

68000 TRICKS AND TRAPS edit / delete
I will probably never find this useful, but it's quite interesting anyway.
to 68000 assembler optimisation programming ... on 14 August 2008
Some interesting stuff about GCC and optimisation; in particular, a good discussion of strict aliasing and how it can help the optimiser.

Paul Hsieh's Square Root page edit / delete
How to calculate square roots quickly. (There's other interesting stuff on the site too, although it's a pain to navigate.)
