Too Long; Didn't Read
Early last year, I started working on a side project to create a websocket server from scratch. I wanted to know what the technical limitations were to serve millions of concurrent connections at scale. Well, I found my answer(s), and along the way I picked up a few extra problems that needed to be solved. The end result was <a href="https://recv.io/" target="_blank">recv.io</a> (receive eye oh), a globally distributed pub/sub network that doesn’t lose your messages.
