Deploying a Keystone App to Heroku

Keystone comes completely set up to install on Heroku in a couple of steps.

1. Sign up for a Heroku account and install the Heroku Toolbelt.

Log in with it and you're ready to begin. Heroku uses git to deploy a new site, so with that in mind:

2. Create a new repository on Github and then clone it.

The Ultimate Git Alias Setup

If you use git on the command-line, you'll eventually find yourself wanting aliases for your most commonly-used commands. It's incredibly useful to be able to explore your repos with only a few keystrokes that eventually get hardcoded into muscle memory.

Some people don't add aliases because they don't want to have to adjust to not having them on a remote server. Personally, I find that having aliases doesn't mean I that forget the underlying commands, and aliases provide such a massive improvement to my workflow that it would be crazy not to have them.

The simplest way to add an alias for a specific git command is to use a standard bash alias.

# .bashrc

developer88

# config/initializers/active_admin.rb

ActiveAdmin.setup do |config|
  config.current_user_method = :current_user
  config.authentication_method = :authenticate_user!
  config.before_filter :admin_role_filter
end


# Adding all recource names to Permissions table after ActiveAdmin is loaded

#List vms
VBoxManage list vms

#get status of time sync
VBoxManage getextradata <vm-name> VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled 

#NOTE: Make sure to restart the VM after changing these settings.

#disable time sync
VBoxManage setextradata <vm-name> VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled 1

In penance for cracking stupid jokes on Twitter, here's my Emacs cheat sheet. Emacs has a steep learning curve, so I've tried to order them by importance so you could learn them in stages.

One overall rule of thumb: pay attention to the minibuffer (the line at the bottom of the editor). It will often guide you through a process, and also gives you hints about what state you're in, such as the middle of a multi-chord sequence.

The other rule of thumb: when in doubt, C-g it out.

Basics (mandatory)

You simply can't get by without having these at your fingertips.
