Homework8.4: Linux

Complete this homework on your own blog, and send me the link.

The Linux operating system was developed by Linus Torvalds in the 1990s. The operating system is gaining some ground on the more well-known operating systems: Windows, Mac OS, and UNIX. These three popular operating systems have one thing in common: They generate great amounts of money for their developers. Linux, on the other hand, is available free of charge; its developer has not become a multimillionaire.

Why did Torvalds offer the code free of charge?

Why does he continue to do so today?

What is the philosophy behind his unique offering and how is it changing the world of software?
