Computer Letter: Sharing software

ONE SMALL minority of users totally ignored by David Hewson's piece is the experts - those who converted from trainspotting because it was getting too fashionable. I am writing up a PhD thesis on an esoteric Electrical Engineering subject, using only public domain software. The operating system is BSD Unix - the real thing from Berkeley, the graphical interface X11 - the real thing from MIT. The editor is GNU Emacs from the Free Software Foundation and the print preparation program LaTeX from Donald Knuth.
