"On a tight budget, but want to monitor your business, home, or maybe just your baby's room? Using Linux and the webcam_server project, you can set up a poor man's monitoring solution quickly and easily.
"Setting up a system to broadcast pics or video from a Webcam may sound like quite a challenge. Believe it or not, it's really fairly easy to get up and running. All you need is a Linux machine (In this case, Ubuntu), a Web server (Apache), a webcam, and a little tool called webcam_server. Once you are done, you can point that Webcam to your target and then view it from within a browser. If your machine housing the server is available to the outside world, you can share that link or view it from anywhere you have access to a Web browser, including your mobile device!

"With Linux, everything is a file ? and that includes devices, processes, and system information. /proc allows you to take a look at these 'files'. /proc (short for "process filesystem") isn't 'real'; it's a virtual filesystem, generated at boot and updated regularly by the kernel. Instead of storing information on disk, when you look at something in /proc, it fetches the information from the kernel to output as a file. This is great both for system communication (utilities can operate in userspace, rather than in kernel space), and for investigating your system's innards.
"/proc and processes
"If you type ls /proc, you'll see a set of numbered directories. These are your processes: one directory per process ID. Look at your process list with ps -A, and pick one to investigate. (Note that unless you have root/sudo access, you're best off choosing a process that you own.) Here's a sample process from my ps output:"
