In computer world, it seems like hardcore programmer is used in this sense and "Real programmer" phenomenon is compared to No true Scotsman fallacy. [However, hardcore programmer might be used in other senses as well.]
The term Real Programmer in computer folklore has come to describe the archetypical "hardcore" programmer who eschews the modern languages and tools of the day in favour of more direct and efficient solutions—closer to the hardware. The alleged defining features of a "Real Programmer" are extremely subjective, differing with time and place, in the fashion of the "no true Scotsman" fallacy. [Wikipedia]
Definition of "real programmer" from "The New Hacker's Dictionary" by Eric S. Raymond:
Real Programmer: [indirectly, from the book "Real Men Don't Eat Quiche"] n. A particular sub-variety of hacker: one possessed of a flippant attitude toward complexity that is arrogant even when justified by experience. The archetypal `Real Programmer' likes to program on the bare metal and is very good at same, remembers the binary opcodes for every machine he has ever programmed, thinks that HLLs are sissy, and uses a debugger to edit his code because full-screen editors are for wimps.
