If you're on a Linux related forum, you'll see variations of this a few times per week:

• OMG help I have less than 1% free memory!
• I'm only running Apache but have 2GB memory used. How do I see what's using it?
• i think Linux has a memory leak, it's gradually filling RAM until i reboot

LinuxAteMyRam.com aims to be the default response to such questions. The goal is a simple, reassuring and informative source of information about the wonders of disk caching and what it means for performance and monitoring tools.

Issues and pull requests welcome.
