One way that would have avoided sounding negative, and which (I HOPE) would have got you a lot more upvotes, would have been to say something like "This is a nice demo! Here's some further reading for these algorithms {CITE}, and here are some other implementations if different languages {CITE}", with a bit of discussion of where you used them and the problems you solved.
Personally, I'd much rather see someone's implementation of something that yet another {article I don't like}.
