50 Years Later, MIT Looks Back At AI and Networking Pioneer Project MAC 50

v3rgEz (125380) writes "Fifty years ago, a major project that ultimately seeded much of today's computer technology was created at MIT: Project MAC, and the Multics operating system initiative within the project. Daniel Dern interviews some of the key figures involved in the pioneering project, looking at how one laboratory helped spawn Ethernet, AI, and dozens of tech companies and other innovations that took ideas from the lab to the personal computer."

    Unix is not Multics and that is really all you need to know about Multics

    There are many interesting aspects about Multics that deserve to be heard about if not studied. To name a few: the second-dimension access system or protection rings [wikipedia.org] via "ring brackets" that allowed a 'r', 'w' or 'x' access to a "segment"/file depending on the caller (user or daemon) own "running ring". Thus, a lower (higher privilege) ring program would extend its r&|x access via brackets to allow a user to enter that program (a "gate"). For instance the continuums [multicians.org] (now forums) were usually running in ring 3, while a simple user was in 4 (the core system was in 0). Multics had also convenient and powerful ACL [multicians.org], accesses provided to user/group-project/login-mode. Using long names or short names for a file(segment)... Studying a bit of Multics helps to realize that most of OSes concepts were already invented ~50 years ago...

Nobody's gonna believe that computers are intelligent until they start coming in late and lying about it.
