From time to time I'm going to be posting a collection of cool links to gamedev-related stuff that I found on the internet over the last couple of weeks. This is the first post in that series.
Introduction to Digital Filters is a free online book by Julius O. Smith III. It's a fairly easy read and serves as a great introduction to the theory. The main page of his site has some other cool online books too, in particular one on the Mathematics of the Discrete Fourier Transform.
smallptis a Monte Carlo path tracer in 99 lines of C++ written by Kevin Beason. It comes with source and a cool presentation that explains all 99 lines in detail.
Calibrating Lighting and Materials in Far Cry 3
There were lots of great real-time graphics courses at SIGGRAPH this year. Unfortunately, I couldn't attend this year. However, most of the slides are online. Stephen Hill is keeping a great link collection to all SIGGRAPH talks. One talk that I liked in particular, is Steve McAuley's Calibrating Lighting and Materials in Far Cry 3 from the Practical Physically Based Shading in Film and Game Productioncourse.

Rick Skorski has been posting an interesting, ongoing series on the x64 ABI on Windows over at AltDevBlogADay:
