Ever go out with your laptop and realize you left something important on your computer at home? One way to solve this problem is to use a service like Dropbox, so your files are with you everywhere you go. However, it’s also handy to know how to use your home computer from anywhere. With a simple app, you can log into your home computer from another machine and use it as if you were sitting right at your desk—whether you just need to grab a quick file or access a program you don’t have elsewhere.
