My "best" answers:
- How does x86 paging work?
- What is a mixin, and why are they useful?
- How to use GLUT/OpenGL to render to a file?
- What does "static" mean in a C program?
These are answers on which I worked a lot, and/or contain hard to find useful information. They are not necessarily the most upvoted ones.
