I'm very weary about this conceptually. If you don't know what a piece of code is doing, then you shouldn't be putting it into your project; because when it breaks, you wont know how to fix it. So a cookbook with explanations would accompany this nicely.

Licence concerns me, the page states (We've searched so you don't have to) are you certain you are legally allowed to publish these code samples? Creating your own is fine, but if you've searched places like blogs, stack overflow, etc, you could be infringing copyright. I'll release code samples for free use, but you aren't allowed to re-publish them or make a profit off of them.
