Programmer Bedtime Stories
summary
Four short fables expose concrete bugs and costs: a Python remove-below-average recursion that iteratively trims a 10,000-soldier army down by 3,300 then repeatedly until 612 remain, letting a merchant exploit the process; a weight-miscommunication where 16 cows sell for 14.9 boulders because of Giga vs GiB ambiguity; and a JavaScript scope error where using var instead of let makes loops share an index, producing one tart instead of many — a real-world scoping failure that kills the enchantment.
