Some 'best practices' are no longer 'best'. There are newer and better tools available to solve problems that even a couple of months/years ago required a lot of hacking and/or ugly code. In this talk I'll show you some examples of patterns and solutions that no longer apply and current/latest best practices. Also why they are better, why you should upgrade your code as soon as possible, and how to deal with 'obsoledge'. Includes Request/Resposne, Databases, Templates, APIs, 3rd parties, and more.
