Saw Richard Stallman and his copyright presentation

I saw Richard Stallman (of Emacs and GNU FSF) at Virginia Tech where he spoke at invitation of the ACM. He spoke on copyright, what he perceived as the problems with it and how he would fix it. (Basically he proposed reducing the copyright term substantially to 10 years, a number he thought about right but was willing to say that it should be tried and adjusted if appropriate). He also advocated dividing the copyrightable works into 3 classes and treating each class differently. The first class were reference works, textbooks and like (things you need to do your job). For these advocated essentially a GPL approach anybody could copy or modify and redistribute. The second class were “impressions”, works of opinion etc. These he would allow free noncommercial distribution but no modification. The third class was entertainment, music, video, art etc. These he would allow free noncommercial distribution but was ambivalent about modification saying there were good arguments to be made for modification and nonmodification (for example to preserve artistic integrity). Obviously he covered more, a few political comments some of which I agreed with and some I did not. Afterwards he sat down, answered questions, during which he took his socks off. All in all an entertaining and thought provoking session which perhaps got off to a slow start.

Retro Computing Hercules IBM 370 on a PC Hercules an IBM S/370 and ESA/390 Emulator than runs on Intel architecture. Of course it needs an operating system. Some of the older MVS, MVT, VM 370 R6 operating systems are in the public domain, but not the manuals. (Interesting that they are in the public domain perhaps they were not copyrighted at that time because it was believed that software was not copyrightable/patentable?
