Redis Watch Trivia "Facts" - a Meta Archive

Redis Watch Trivia "Facts"

a Meta Archive

Look for a new #RedisTrivia fact every Thursday with your Redis Watch newsletter :)

Lifted with permission from the Redis Watch Archive: https://redislabs.com/redis-watch-archive

  1. Redis stands for REmote DIctionary Server
  2. everybody knows that Redis' default port is 6379, but have you ever wondered why? The answer is that 6379 spells MERZ on the phone's keypad (want to know what MERZ is? Read the appendix at http://oldblog.antirez.com/post/redis-as-LRU-cache.html [warning: slightly NSFW links inside])
