Yubikey - PGP - SSH - Git Signing

Instructions largely found from here: https://www.esev.com/blog/post/2015-01-pgp-ssh-key-on-yubikey-neo/ https://www.ahrenstein.com/blog/using-a-yubikey-4-and-gpg-for-ssh-on-a-mac/

Go here if you want to update expiration dates on your keys: https://www.g-loaded.eu/2010/11/01/change-expiration-date-gpg-key/

Best to store master key and backups on an encrypted removable drive. I formatted a USB drive for this purpose.

  1. Mount the encrypted USB drive and link it in to the default .gnupg directory (this will create a new keyring on your encrypted drive) ln -s /Volumes/NONAME .gnupg

Internet Scale Services Checklist

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."

Basic tenets

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