See user's browsing history through root

Is there a way to deny a user of linux OS that doesn't have root access to delete their browsing history? Or to see their browsing history even if they delete it?

I'm asking because I recently got a laptop and live with some roommates who ask me for it; so I banned access to facebook (because I don't want the battery of my laptop going dead from hours and hours of endless chatting. And after all, is my fucking laptop) through hosts. But I know about proxies and all those websites that exists to avoid this kind of ban, so I want to see if they are using one of these to ban it too.

I'd just like to interject for a moment.

What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use.

Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.

You're right, Dr. Stallman. Have some foot's fungus as a way of apologizing.































Deep inside, we all know Stallman is right.
