A long time ago — 2005, to be exact — I read this article named Making wrong code look wrong, and it was a big influence on me. These days I don’t know how many people use variable naming conventions, but when working on web applications I still like the “us” (unsafe) and “s” (safe) convention for handling user input. As Joel Spolsky discusses in that article, that convention has a good way of making wrong software code look wrong.
