Sorry about being an asshole here, but really. The problem with articles like that, is that a novice developer, with some 5-10 years of experience can pick up an article similar to that one and use such techniques without any need. With disastrous consequences. How do I know it? I've seen it happen. Again and again. Hell, it had happened to myself, years back.
An article like that should start with: "unless you really really know what you are doing and are an adult (20+ years of coding) you should probably avoid using techniques like that in the production code."
