This will provide a much faster and favorable experience VS RDC over network (or worse, the internet). It also gives you free reign to do whatever else you might want to do on windows (which for me isn't much, but a nice-to-have none-the-less).

The following list of commands will get you a free (microsoft sponsored) Windows XP VM environment with IE6 installed. The password is "Password1". When you first login, you will be asked to activate the OS. Do this immediately over the internet. You will get 90 days of activation. Once this runs out, activate the snapshot called "The initial VM state" to go back in time.

% mkdir -p ~/.vm/hdds/windows/winxp-ie6/
% cd !$

% wget http://download.microsoft.com/download/B/7/2/B72085AE-0F04-4C6F-9182-BF1EE90F5273/Windows_XP_IE6.exe
% unrar e Windows_XP_IE6.exe

Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

1) backup production database:
	heroku pgbackups:capture --expire --remote production

2) obtain url string to backup from step 1:
	heroku pgbackups:url --app production_app_name --remote production_app_branch_name

3) transfer backup from production to staging app:
	heroku pgbackups:restore DATABASE 'production_app_backup_url_string_from_step_2' --app production_app_name --app staging_app_branch_name
