I just discovered jsfiddle.net. It's a website that lets you type (or paste) HTML, CSS and JS code and load a specific JavaScript library to test its effects live.

Just as a reminder:

• use the disk sharing icon at the bottom of he VirtualBox window to setup a shared directory (let's say you give it a name of "shareddir")

• open a terminal (Execute cmd)
• type "net use x: \vboxsrvshareddir"

System error 67 has occured.

Let's say you want to install Chamilo on your netbook for a demo... Because Apache uses a lot of memory (and so does MySQL), it is generally considered a good practice to try and use something a bit lighter for your web server This procedure might also work, with a few minor alterations, for OLPC's XO laptops.
