Many times, examples on internet cannot be used in real production environment. They are missing some important things, such as DB transaction, profiling, etc.
Many times, examples on internet give you only fragment of codes, which you cannot make it works and you want the full code.
Many times, examples on internet give you too long explanation and that makes you lose the important points.
So, posts in this site will be short with only important points and code should be always runnable…. not much explanation, the code will tell…
I hope this site can save your time.
