With a little luck, and contributions from all of us (hopefully, Peter will have an open ear for story pitches), GQ could be for code what Make is for the DIY scene.
Here's some hypothetical articles I could imagine reading:
* A critical reading of The TeXbook.
* Bootstrap your own self-compiling mini-language.
* A brief history of asynchrony.
* Fun with Octrees.
* Visualizing strange attractors.
* A security analysis of the SHA-3 contenders.
