In the Star Trek episode "The Trouble with Tribbles," we see a graphic example of how small initial changes can lead to monumental consequences over a fairly short time. In the episode the possible consequences of rapidly-reproducing tribbles were contained and managed, leading to awareness of the effects of "new" species on established societies. A similar story can be seen in the rise of open source software — from Linus Torvalds' first release of source code in 1991, Linux has spread by allowing users to modify, improve and share software. Open source software is now a massive force in technology today. Yet many of us aren't aware of the reach and influence open source has on our personal and professional lives.
