Re: Certification value (was Bitwise operators)
While I understand that certification in and of itself does not create a
good programmer, it is certainly an excellent start. It shows initiative
and willingness to learn in a structured environment, all great
qualities of a team player.
In my opinion, discouraging someone from getting certified or devaluing
this accomplishment is a form of negative energy that I think is
detrimental to Java.
