Is Your UUID Truly Unique?

uuid-memes, database-memes, unique-memes, irony-memes, programming-memes | ProgrammerHumor.io

Checking if your "universally unique identifier" is actually unique by comparing it to a database of other UUIDs is like asking if your fingerprints are unique by pressing them against everyone else's fingers. The whole point of UUIDs is that they're generated to be mathematically unique without needing to check a central registry. With 2^128 possible combinations, you have better odds of winning the lottery while being struck by lightning... twice... on Mars.

Content Example of GPT-4 visual input: icer What is funny about this image? Sneed's Feed Seed formerty Chuck's GPT-4 The sign is a subtle joke. The shop is called "Sneed's Feed Seed", where feed and seed both end in the sound "-eed", thus rhyming with the name of the owner, Sneed. The sign says that the shop was "Formerly Chuck's", implying that the two words beginning with "F" and "S" would have ended with "-uck", rhyming with "Chuck. So, when Chuck owned the shop, it would have been called "'Chuck's Feeduck and Seeduck". Table 3. Example prompt demonstrating GPT-4's visual input capability.
