Dabblers and Blowhards:
To which I'd add, what hackers and painters don't have in common is everything else. The fatuousness of the parallel becomes obvious if you think for five seconds about what computer programmers and painters actually do.
Computer programmers cause a machine to perform a sequence of transformations on electronically stored data.
Painters apply colored goo to cloth using animal hairs tied to a stick.
It is true that both painters and programmers make things, just like a pastry chef makes a wedding cake, or a chicken makes an egg. But nothing about what they make, the purposes it serves, or how they go about doing it is in any way similar.
