NetTuts needs to mention which key derivation function they are using so the community can verify they didn't fuck up again.

I would also recommend that they use this opporunity to teach their web developing users about proper password storage, but after reading their php hashing tutorial[1], I think it's best if their users look elsewhere. The tutorial eventually recommends bcrypt after listing multiple unsafe solutions. I understand that the author is trying to build up to the solution, but the correct solution needs to be in the first paragraph. The incorrect solutions need to be clearly flagged so a beginner skimming through doesn't see "md5" and stop.
