  • Andrew S.Tanenbaum He is also the author of MINIX, a small UNIX clone initially intended for use in student programing labs. It was the direct inspiration for Linux and the platform on which Linux was initially developed. The current version of MINIX, called MINIX 3, is now focused on being an extremely reliable and secure operating system. Prof. Tanenbaum will consider his work done when no computer is equiped with a reset button and no living person had ever experienced a system crash. MINIX 3 is an on-going open-source project to which you are invited to contribute. Go to www.minix3.org to download a free copy and find out what is happening. (查看原文)
