DNS: Two Hard Problems In One

Description

A simple Venn diagram titled "THE ONLY HARD PROBLEMS IN COMPUTER SCIENCE" shows a red left circle labeled "CACHE INVALIDATION" and a green right circle labeled "NAMING THINGS." The yellow overlap in the center is labeled "DNS" in large bold black letters. The meme riffs on the classic Phil Karlton-style joke about cache invalidation and naming being the hard problems in computer science, then identifies DNS as the painful intersection of both. Technically, it lands because DNS combines naming, propagation, TTLs, resolver caches, stale records, and distributed consistency into one operationally fragile system.
