If you ever wanted to install WordPress on your flash drive, here are two tutorials that explain how to do it:

1) http://www.tamba2.org.uk/wordpress/usb/

2) http://ralph.fm/2007/03/08/how-to-install-wordpress-on-a-usb-stick/

Update: Once the local version of your blog is ready to go live, you can easily migrate it to your web server. Andrew Strojny’s tutorial, Convert A Local Wordpress XAMPP Installation Into A Live Site explains the steps involved.

Time to upgrade your development skills with a new language? Why not try Ruby On Rails? Here’s a complete and portable Rails development environment called InstantRails, although you might want to add an IDE (I used Aptana’s RadRails, but it’s not portable).

Instant Rails contains everything you need to start coding, including Ruby, Rails, Apache, and MySQL. It even includes PHP, in case you want to learn that too!
