During source code and application reviews a number of common issues are often seen. Developers making the same mistakes time and time again. There are also those 'unique' issues that only come up once in a while, when people handroll their own methods to solve a particular problem. Over the course of this talk, the speaker will explain and describe a number of issues that he has seen over the last 24 months in locally developed code. This is an opportunity to see what local developers are doing wrong, and why you shouldn't try this at home.
