Planners make up schedules. Frightened coders strive to meet schedules. Real programmers ignore schedules. Real programmers like vending machine popcorn. Coders pop it in the microwave oven.
Real programmers use the heat given off by the cpu.
They can tell what job is running just by listening to the rate of popping. Real programmers know every nuance of every instruction and use them all in every real program. Puppy architects won't allow execute instructions to address another execute as the target instruction. Real programmers despise such petty restrictions. Real programmers don't bring brown bag lunches to work.
