Thanks @ bradfitz - memcached turns 10 years old
This week, memcached, a piece of software that prevents much of the Internet from melting down, turns 10 years old. Despite its age, memcached is still the go-to solution for many programmers and sysadmins managing heavy workloads. Without memcached, Ars Technica would likely be unable to serve this article to you at all.
Brad Fitzpatrick wrote memcached for LiveJournal way back in 2003 (check out the initial CVS commit here). While waiting for new hardware to help save the site from being overloaded, Fitzpatrick realized that he had plenty of unused RAM spread across LiveJournal's existing servers. He wrote memcached to take advantage of this spare memory and lighten the load on the site.
memcached is a distributed in-memory key-value store that uses a very simple protocol for storing and retrieving arbitrary data from memory instead of from a filesystem. To store a value, a program connects to the memcached server on the default port of 11211 and issues a series of basic commands. (Note: a binary protocol is also supported.)

Morin Tastes Own Medicine - to spam or not to spam?
Last Friday Facebook blocked Path’s “Find Friends” feature over brewing spam complaints. Shortly thereafter Dave Morin, Path’s CEO, proudly stated that “Path does not spam users,” but the tactics he is defending today are the very same practices that he himself cracked down on as “spam” when he was running the Facebook Platform. I watched the crack-down from the front-row at iLike, an early Facebook platform partner.
Compare Morin’s description of Path’s “feature” to the Facebook policy that was put in place while Morin was the head of developer relations for Facebook Platform. The official Facebook policy was that apps were forbidden from doing exactly what Morin now calls “not spam”:
Specifically, an app with a pre-selected (opt-out) checkbox sending messages to your entire address book if you simply pressed “OK” was what Facebook, under Morin’s oversight, considered to be a punishable violation of the terms of use. Let me say that again: the exact form of invitation interface Path uses was specifically called out and forbidden by Facebook under Morin oversight, in order to preserve the sanctity and user-experience of the Facebook platform ecosystem.
