This is great, both as actual content and advice to (beginner) programmers but also as "link-bait" in the best sense of the word, i.e. content that is very likely to gather a lot of inbound links.

As a very active Stack Overflow user, I immediately start thinking about how many questions that are going to get links to this as comments. :)

Well done, I hope it helps although I guess the supply of beginner programmers won't dry up over night.
