NEW! Fan of the list Diego Peinador has done what I've been too lazy to do for years: stand up an easily-remembered domain for The Rules, complete with one-per-page URL schema - e.g., for Rule 42 just visit https://the-rul.es/42/

Thanks Diego! <3

(subject to additions, but rarely changes)

rule 0: It has to work.

rule 1: As simple as possible.

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

Does the design expect failures to happen regularly and handle them gracefully?
Have we kept things as simple as possible?

Ruby, RVM and Mountain Lion

Key problems

Mountain Lion (10.8) has three main difference compared to Lion (10.7):

XCode 4.4 does not install Command Line Tools by default
X11 isn't available anymore
The installed version of OpenSSL has some bugs
