My biggest problem with the article is that it's essentially a puff piece about how awesome the writer thinks he is, and how special he is for being able to learn the basics in a short amount of time. The post is entirely too hand-wavy about actual details; telling someone to read some blogs, Q&A sites and code doesn't help anyone.

Where is the substance? Were there any interesting ah-ha moments? What would he do differently? What guidelines would he give to someone else in a similar position? How did he find an appropriate mentor? What was he surprised to learn? What can he do now that he couldn't do when he started?

There's so many things he could have documented that would have been helpful. He didn't write any of them. Instead, he made the implementation details seem mystical and gives the opinion that "hard work" (whatever that is) is the only key.
