Although my previous post is long, it's well worth reading being that it points out huge flaws in these 'tricks' and also gives the information about why you SHOULDN'T use these 'tricks'. The information is very sparse on the site and doesn't include any information of WHY these 'tricks' do what they do...
A good analogy would be a mechanic saying "a quick replacement for a fan belt is a pair of ladies tights." He misses out the fact that it is an inefficient replacement and is only meant as a temporary fix, being that it won't take long for the tights to break.
Some of the 'tricks' he gives you are quite dangerous...
