in reply to do you know Perl ?, or do you know ?
I've seen this described as the difference between a Programmer and a Developer.
The Developer can take the real world problem, break it down into pieces (steps, objects, whatever...) and then build those pieces.
The Programmer can write code that executes according to instructions to complete a well-defined task.
The Programmer builds the pieces. The Developer determines which pieces should be built.
Sun is one place that buys into this distinction. At Sun, getting a 'Sun Certified Java Programmer' certification is (can be) a step on the road to getting a 'Sun Certified Java Developer'.
