re: http://www.garlic.com/~lynn/2013m.html#36 Quote on Slashdot.org not only didn't Pascal sofware have the vulnerabilities epidemic in C language software ... but Multics PLI also didn't have those vulnerabilities ... old posts referencing IBM Research paper http://www.garlic.com/~lynn/2002l.html#42 Thirty Years Later: Lessons from the Multics Security Evaluation http://www.garlic.com/~lynn/2002l.html#44 Thirty Years Later: Lessons from the Multics Security Evaluation http://www.garlic.com/~lynn/2002l.html#45 Thirty Years Later: Lessons from the Multics Security Evaluation original paper now 40yrs ago http://csrc.nist.gov/publications/history/karg74.pdf ibm research paper a decade ago http://www.acsac.org/2002/papers/classic-multics.pdf there was little competition between the science center on the 4th flr tech sq with cp67/cms (later morphs into vm370) and project mac on the 5th flr and multics ... some past posts mentioning tech sq http://www.garlic.com/~lynn/subtopic.html#545tech from long ago and far away http://web.archive.org/web/20090117083033/http://www.nsa.gov/research/selinux/list-archive/0409/8362.shtml and theirs http://www.multicians.org/mgs.html#SiteN another cp/67 story (USL was in another bldg in tech sq) http://www.multicians.org/thvv/360-67.html complete list of mutlics sites http://www.multicians.org/sites.html psuedo competition was one of my hobbies was providing highly modified custom virtual machine systems for internal datacenters. it wasn't "fair" to compare total number of multics to total number of vm370 or even total number of multics to total number of internal vm370 ... but could compare total number of multics to number of internal csc/vm sites (well over 100 at one point). old email referencing csc/vm http://www.garlic.com/~lynn/2006v.html#email731212 http://www.garlic.com/~lynn/2006w.html#email750102 http://www.garlic.com/~lynn/2006w.html#email750430 another multics http://www.multicians.org/mga.html#AFDSC and I tweaked them with AFDS looking at 20 vm/4341s which turned into 210 vm/4341s http://www.garlic.com/~lynn/2001m.html#email790404 posting in multics discussion group http://www.garlic.com/~lynn/2001m.html#12 -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
