Colin writes – “Linux Infrared Remote Control (LIRC) allows you to use inexpensive hardware to control your Linux PC with a TV remote control. Why would you want to control your PC with a TV remote control? A number of reasons are possible, the most obvious being MythTV, which I wrote about earlier for LJ.com. You might want to use LIRC for presentations, so you can step out into the audience and still change slides on your laptop. Or, LIRC can be used when you are keeping a machine out of the way somewhere but still want to control it.” [via] – Link.
