Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Python 2.x

$ python -m SimpleHTTPServer 8000

var parser = document.createElement('a');
parser.href = "http://example.com:3000/pathname/?search=test#hash";

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

--This script attempts to migrate the users
--from the old ASP.Net Membership tables
--into the new SimpleMemberShip tables
--The SimpleMembsership uses more secure password hashing, as such the old password hashes won't
--work with the SimpleMembership tables.
--As far as I can tell you have two options
--1) Get your users to reset their passwords
--2) Update your web.config to force SimpleMembership to use the old SHA1 format.  See more details
