  • Exactly these codes will end up at the Daily WTF

    by Adam Nemeth,

    The main property of failures is that everyone believes they do the best job possible. They don't want too much overhead of course, whatever that means for them - wether be dumb work or cleverness - yet somehow projects still end up on that website.

    I've seen applications on a daily basis where they followed Alex' advice, like, they actually forked an application instead of providing clever extensibility, ending up with managing two full applications for more than 10 years, where one even had to stay in an unsupported platform. I see code without any design patterns or config files.

    The only reason those codes didn't end up at Daily WTF is usually NDA. A full team of outsourcing company can laugh at you just before committing such errors themselves.

    So, remember: that dumbass who did that crap and can't code, in the eyes of your project's next maintainer (or the first one who doesn't know you) is you!

    Slides do not load for me. Are they available anywhere else? Can the feed be fixed?
