 It is good to know what's exactly that variable, to know if we are dealing with a file, with a directory, or with a value, I personally use for that a suffix (ending in) in the variables like '''_v''' for values, '''_d''' for identifying directories, '''_f''' for identifying a file, there's also a good practice to use '''_''' as ''prefix'' for any local variable.

+=== Big Applications ===
+Big applications are very hard to found where a bug is to fix it, very hard to maintain, etc, the best way to avoid these pains are:
+1. Keep everything modularized but independent, this means that every function, tool or feature, can be called independently without depend of any other thing, think about use external commands
+1. When those external commands or global tools/functions are called, make sure to include a debug entry showing how it is called, on this way you can easly reproduce the same callback outside the application
+1. Never delete or rename old functions, you will have tools that still depend of it, instead, replace it with the new function and add a warning line telling the user that this function is deprecated
+1. Never refactor changing the final behaviour, unexpected results will happen to applications that uses these functions
