There's a great, fun, programmer-centric website called thedailywtf.com (sorry, I just scheduled the rest of your afternoon for you). Developers can submit WTF's that they've found in other's code - as the site admin says, "curious perversions in information technology".<p>One thing that strikes me about the majority of the submissions, as funny as they are, is that they mostly boil down to "so-and-so didn't know that such-and-such feature existed, so wrote reams of code to implement that feature in a complex way". It also strikes me that just this article's sort of analysis of "prolific" (aka "good") engineers/programmers drives this same sort of behavior. If every developer is supposed to be committing code all day, every day, there's no time left over to read the product documentation, try out a new feature, review a reference implementation, read a blog post: to be "good", you must be spending as much time as possible _typing_, because that's what you're paid to do. This (ubiquitous) management mentality is how we end up with roll-your-own crypto, or five competing Javascript frameworks, parsing using regular expressions... it's not so much that what they did was wrong - and trust me, if it works, it won't be removed - it's that it's pointless.
