Free Software

Definition (Free Software — a definition)

Free/Libre/Open Source Software (FLOSS) is computer software thatgives users the freedom to run the software for any purpose as wellas to study, modify, and distribute the original software and theadapted versions.

How is that different from “usual” (proprietary) software ?

Why bother ? — as citizens

Lester picked up a screwdriver. “You see this ? It’s a tool.You can pick it up and you can unscrew stuff or screw stuffin. You can use the handle for a hammer. You can use theblade to open paint cans. You can throw it away, loan itout, or paint it purple and frame it.” He thumped theprinter. “This [ Disney in a Box ] thing is a tool, too, but it’snot your tool. It belongs to someone else — Disney. It isn’tinterested in listening to you or obeying you. It doesn’t wantto give you more control over your life.” [. . . ]

“If you don’t control your life, you’re miserable. Think ofthe people who don’t get to run their own lives : prisoners,reform-school kids, mental patients. There’s somethinginherently awful about living like that. Autonomy makes ushappy.”

— Cory Doctorow, Makershttp://craphound.com/makers/
