If you don’t know this already, I have a Psychology Degree and I’m build websites for a living. I have no formal training in programming or building websites. I often get nervous about the holes (large ones I have no doubt) in my knowledge due to the fact that I’m self taught. According to some people like me need to do some more learning.
While the article is centred around topics for game developers there are lots of articles that are good for any programmer in any language. I’d love to see a list like this specifically geared towards PHP and web programmers.
I also know from talking to other developers that we all have thoughts like that. Many of us have some worry that someone else will look at our code and then find out that all our knowledge is a sham.
