what can a PC really do? from Jack prabha's blog

Spreadsheets, word processing and databases. Limiting a modern PC to running these bread and butter tasks is like buying a Ferrari and driving it to the corner shop.

The question is, with a fast processor, a quick internet connection and a little imagination, what can a PC really do?

We've asked our writers to kick back and let their imaginations run riot. Security expert Jon Thompson inevitably got involved with spying and subterfuge, uber geek Mike Williams remote controlled his home PC with Twitter and joker Jamie Middleton decided to change the world. So read on and spare a thought for those PCs condemned to a life of office work.

Keep high-def YouTube videos

There are quite a few sites, plug-ins and apps that allow you to download videos from YouTube in Flash Video format. However, these can be quite a poor reflection of the originally uploaded video. In a large and increasing number of cases, you can also download high-quality and even high-definition versions of YouTube videos by slightly changing the URL.

It works like this. When you find a video you want to download, change the domain from www.youtube.com to www.youtubekeep.com and hit [Enter]. You'll go to a YouTubeKeep page that features download options for the video. Select what you want, click 'Download' and save the file. Don't be tempted to download illegal content and never redistribute what you've downloaded.
