Git clone using ssh agent forwarding and sudo
SSH agent forwarding is great. It allows you to ssh from one server to
another all the while using the ssh-agent running on your local
workstation. The benefit is you don't need to generate ssh key pairs
on the servers you are connecting to in order to hop around.
When you ssh to a remote machine the remote machine talks to your
local ssh-agent through the socket referenced by the SSH_AUTH_SOCK
environment variable.
So you the remote server you can do something like:
# This allows developers to pass an Active Model object
# to within, check and uncheck. This is very useful when
# used with `content_tag_for` since `content_tag_for`
# generates an unique dom id for each object. With this
# module, we can write:
#
# within comment do
# click_link "Destroy"
# end

ruby-1.9.3-p327 cumulative performance patch for rbenv

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

FSSM based FileWatcher for Rails

Rails 3.2 ships with a simple FileWatcher that only reloads your app if any of the files changed.

Besides, it also provides a mechanism to hook up your own file watcher mechanism, so we can use tools like FSSM that hooks into Mac OS X fsevents. This is an example on how to hook your own mechanism (you need Rails master, soon to be Rails 3.2):

  1. Copy the 2_file_watcher.rb file below to lib/file_watcher.rb

  2. Add the following inside your Application in config/application.rb

if Rails.env.development?

SSH known_hosts tools
# This is a short collection of tools that are useful for managing your
# known_hosts file. In this case, I'm using the '-f' flag to specify the
# global known_hosts file because I'll be adding many deploy users on this
# system. Simply omit the -f flag to operate on ~/.ssh/known_hosts
# Add entry for host
ssh-keyscan -H github.com >> /etc/ssh/ssh_known_hosts
# Scan known hosts
ssh-keygen -f /etc/ssh/ssh_known_hosts -F github.com
