10 Best Ways to Use Your PC While You're Sleeping or at Work
Run a Music Server
There's no need to drag your music collection between home and office. Give your iPod or Zune a rest and use our own Norm Chan's How To: Stream Your Music Library to Any Computer tutorial to bring your music to your office. The most time-consuming step (page 2) is importing your music into Netjukebox, so it's a perfect candidate for running it before you hit the hay or head to the office.
Compiling Code or Render Graphics
Compiling code and rendering graphics are among the most time-consuming tasks you can perform, so you shouldn't waste precious playtime by watching your computer munch program and video bits.
Start these processes before you clock out for the evening or as you start off to work. To make sure they run as quickly as possible, set your computer's power management for high performance and turn off other tasks that might interfere, such as Windows and application updates and other processes (such as the ones listed in this guide). If you're rendering graphics to an external drive or building a DVD or Blu-Ray disc, make sure your external drive is ready to roll and that you have a suitable blank disc in your drive.
Contribute to Distributed Computing
You can "give something back" to the world by devoting unused computer cycles to a cause you support. You can help make scientific discoveries or fight deadly diseases, and there's no shortage of causes looking for your help. For a list of projects, see these Maximum PC stories: Facebook and Intel want You to Donate Your Spare Cycles, Freeware Files: Five Free Distributed Computing Projects for your Idle PC!, and New Distributed Computing Initiative Wants to Create Artificial Life.

How to Manage It All When You're Away
Whether you're running apps that include built-in schedulers or need to start them yourself, you're going to want a way to log into your home PC from the office and keep an eye on what's going on. You could use commercial services like GotoMyPC, but if you're looking for a powerful freebie, check out the remote connection apps in our story The Ultimate Free Network Applications, Period. During your coffee breaks or lunch, you can stay in complete control of your PC at home.
