Safe

• Add a new column
• Drop a column
• Rename a column
• Add an index concurrently (Example), Note: it will still take a long time to run the migration, but it won't write-lock the table.
• Drop a constraint (for example, non-nullable)
• Add a default value to an existing column

# Atom will evaluate this file each time a new window is opened. It is run

If someone forks a gist and you'd like to merge their changes. Do this:

1. clone your repo, I use the name of the gist

    git clone git://gist.github.com/1163142.git gist-1163142
   

2. add a remote for the forked gist, I'm using the name of my fellow developer

    git remote add aaron git://gist.github.com/1164196.git

Git hooks for better pivotal integration:

• pre-commit:
  • prevents commiting on a branch that is not suffixed by an issue number. Some special branches (develop, master) and hotfixes are not constrained
  • lints modified python files and exits upon non correctly formatted modules
  • other formats (js, scss) have pending code that is not currently called as the workflow for front code is not clear
• prepare-commit-msg: prepend issue number to commit message if it's missing and if it is set in the branch name (see pre-commit hook)
• post-checkout: [optional] automatically update submodules when checkouting a branch (requires to define the AUTO_SUBMODULE_UPDATE environment variable)

For easy setup:

[user]
	name = Firstname Lastname
	email = username@myEmail.com
[alias]
	co = checkout
	cot = "!f() { git branch | grep $1 | xargs -I {} git co {}; }; f"
        b = branch
        pu = push -u origin HEAD
        ci = commit
        st = status

// Use Gists to store code you would like to remember later on
console.log(window); // log the "window" object to the console
