So is the standard Rubik’s cube so easy that you’re bored with it? Can you solve it in 12.1 seconds?

Well, try your hand at a 4D Rubik’s cube.

Then, if your head hasn’t exploded, check out the 5D Rubik’s cube! From the site: “In the spirit of taking things too far, here is a fully functional 5-dimensional analog of Rubik’s cube.”

Sadly, 5 people have already solved the 5D cube. You can’t be first.

Cameron’s recent data loss is an example of why online back up will become an integral part of home computing in the years to come. As our memories are increasingly stored in digital format (I know in the 9 months of my son’s life there has not been one film based photograph of him taken) people will be looking for a secure off site means of ensuring no harm comes to their pictures or files. Often though, like Cam, it won’t be until after a disaster has hit

I’m currently using Mozy; a free, automatic, secure back online back up system from Berkeley Data Systems. It’s simplicity itself – you download the application, tick the boxes on the predefined back up sets (such as ‘Word Documents’, ‘Music’, ‘Mo vies’,'Photographs’,'Financial Records’ etc), Mozy tracks down all your files and away it goes. You can define your own back sets if you wish and even drill down to the file level to add or remove files for a particular set.

Mozy claims to use differential backup, so it should only back up the bits of your Outlook file that have changed, but I haven’t found that to be the case in my instance. The Mozy icon lives in your system tray and behaves itself very well by only backing up when your system is idle. My only problem with this has been it back ups when I have an unattended torrent going so it can impact on your bandwidth.

You get 2G of backup for free, which covers most of my documents save for my music and video collections. There is a premium service, currently offering up to 20G for USD$39.95. If you want to try it and use my referral link https://mozy.com/ref/UTVC5L we both get an extra 256MB of back up space.
