This is a series of small articles / tutorials based around virtual memory. The goal is to learn some CS basics, but in a different and more practical way.

For this first piece, we'll use /proc to find and modify variables (in this example, an ASCII string) contained inside the virtual memory of a running process, and learn some cool things along the way.
