The free-software movement is devoted to making the source code of computer programs available to anyone, at no charge, so that the programs can be collaboratively modified and improved. But understanding how free software (or its close cousin, open-source software) is created and maintained can be life-changing even for people who will never write code, says ­Christopher Kelty, PhD '00, an associate professor at the Center for Society and Genetics and the Department of Information Studies at UCLA. In his book Two Bits: The Cultural Significance of Free Software, Kelty writes, "People--even (or, perhaps, especially) those who do not consider themselves programmers, hackers, geeks, or technophiles--come out of the experience with something like religion, because Free Software is all about the practices, not about the ideologies and goals that swirl on its surface." The free-software community, Kelty says, consists of people who come together to build practical alternatives to the status quo--and to maintain, improve, and share them. Some have devoted countless hours to building the Linux operating system and then freely distributing it so that others can use it, understand it, and modify it to suit their needs. Kelty thinks that anyone who understands this process will wonder how to create similar communities elsewhere--around "movies, music, science or medicine, civil society, and education," he writes.

Kelty's own "religious" experience came while he was working on his PhD through the MIT Program in Science, Tech­nology, and ­Society in the late 1990s. For his dissertation, he followed the teleradiology startup ­Amicas, then run by Sean Doyle '83 and Adrian ­Gropper '74; in the process, he got caught up in the appreciation for open standards and free software that drove the founders to push for using Internet standards in medical systems, rather than using proprietary systems. While Kelty had always wanted to be able to hack software, he'd also believed he needed a computer science degree to do so. "When I discovered free software," he says, "I realized, 'Oh my God, I could actually sit down and look at this and learn the entire thing on my own, by communicating with the people who created it.'"
