I think the blogpost is worse than helpful, as the author is simply parroting common hiring tropes, then adding misleading advice. Consider:
* He recommends CLRS for learning the basics of algorithms. This is like reading baby Rudin to learn about the basics of numbers.
* He edited his post 2-3 times because he can't identify whether Common Lisp is a purely functional language or not.
* He mentions that side projects don't need to be complex, then suggests "simple" iPhone apps or open source libraries. In practice, neither of these is "simple."
