Most of these slides are in gzipped postscript (*.ps.gz) format.
If your browser cannot deal with this format, the link
http://www.csl.sri.com/cgi-bin/rushby/unzip.pl?~rushby/slides/xxx
will generate plain postscript, and the link
http://www.csl.sri.com/cgi-bin/rushby/ps2pdfslides.pl?~rushby/slides/xxx
will convert to PDF, where xxx should be replaced by the
basename of the file.
