Welcome to another issue of Full Circle magazine. ast month, Andrew gave us his Top 5 Media Center applications. This month I've written a How-To on using Ubuntu on an Acer Aspire Revo to create the foundation for Boxee. For under £150 I've created a fantastic media center L which not only looks great, it's fully customizable! That's my media center story, but don't forget to read the My Story articles which this month focus on Ubuntu, Linux and open-source in public education, as well as how one man went from using old (modern at the time) computers, to using Ubuntu.

Just drop the correct file or folder into options, and a MUCH nicer Web interface. Additionally, it's the Ubuntu One folder, and watch everything automagically cross-platform (you can use it on Windows, OS X, and even the sync up.

One of the coolest synchronization programs around is . It's a Gnome project created with the purpose of syncing anything with anything. So, you can sync your photos to Facebook, Tomboy to Backpack, and folders to folders. You can also sync across computers and to external media, like iPods and hard drives. It takes some getting used to (it's pretty dissimilar to anything I've ever used before, so the interface feels kind of weird), but once you get used to it Conduit is an incredibly powerful tool.
To install Conduit, use the ` ` package in the `universe` repository.
