   IIRC the idea is that executables go in specific places in your $PATH and   
   are not found if not in that path. The './' tells the shell you are using   
   to look in the current directory, '.', for the file to execute you append   
   the '/' because in unix file systems files prepended with a '.' are   
   "hidden" so the '/' is used to differentiate. Searching in the   
   current directory, '.', is not done by default for security reasons.   
      
   For fun you could place your executable one directory up and use '../' to   
   run it. The '.' and '..' are file system place holders for current   
   directory, '.', and directory one level up, '..'. If you want to know more   
   about the Linux directory structure go have a look at:
