What’s what? Open source, free software, GPL, LGPL…

I’ve touched on the relationship between free software and open source several times,
but only today did I come across an older article by Milan Zamazal
(zamazal.org) with the rather unwieldy title
Free Software, Open Source, FSF, OSI, RMS, ESR, GPL, LGPL… Confused?.
The author explains the basic difference between free software and open source, touches on licensing questions (GPL, LGPL, BSD),
and discusses how free and proprietary software can work together. If you’re at sea with these terms or they aren’t quite clear, it’s a good place to start.
