I've always been curious about hex editing, i know how to convert from base 10 to base 16 i just want to know what exactly can hex editing do, can you only edit the parts that are written in ASCII, or only most of the time? is it worth learning? please help, i need to know these things, my quest for knowledge will never end? also does anyone know what some good and productive there is for me to do online? heh

Hex is more commonly used referring to memory pointers (and other hardware associated stuff) and is unneccessary for regular programming.
