Seems a fair bit of it was copy pasted without attribution or consent. Normally this wouldn't be a biggie for a (presumably) casual side project, but intellectual property rights are listed explicitly [1] for the website under the "Terms of Use" tab displayed prominently at the top of the page.

I still could never blame someone for showing a little bit of work, or hell even for self-promotion when you're just getting started. But if your gonna copy-pasta you might as well leave the code comments explaining things a little bit!
