Having a class on history of the hacker culture in the dgplug IRC channel has been highly interesting. Only within moments after starting the journey in 1955/56 at the MIT TX-0 computer, my Wikipedia tabs popped up almost by themselves, going from TX-0 to Hacker to Hacker Culture to Tech Model Railroad Club and Richard Stallman. By the end of the day I ended up installing FreeBSD and Plan9 on virtual machines on my laptop and began to explore those (what a weird thing, this Plan9, but interesting and consistent in concept)
Obviously, Richard Stallman had a great influence on hacker culture, the free software movement and actually on the working environment that I use right now and every day. After watching some talks and interviews, I realized that this guy really has the 100% freedom in mind (which ironically seems to be quite constraining in some way), avoiding any proprietary software, but also boycotting a whole bunch of other services, tools, hardware and whatsoever if they violate against his philosophy.
So I was interested in the OS and tools that are actually approved by Richard Stallman and found a good list here. I don't remember how often I checked that box saying "install non-free packages" on my OS installations, without thinking twice. I will do now, and I think I might try out Parabola GNU/Linux and stay free, by avoiding proprietary software as good as possible. Judging from the post on stallman.org, not even he can manage to get the 100% he aims for; sometimes a trade-off is necessary until a better solution is found or created.
So I start to search for it and/or to create now.
