Tanenbaum–Torvalds debate Tanenbaum–Torvalds debate The Tanenbaum–Torvalds debate was a debate between Andrew S. Tanenbaum and Linus Torvalds, regarding the Linux kernel and kernel architecture in general. Tanenbaum began the debate in 1992 on the Usenet discussion group comp.os.minix, arguing that microkernels are superior to monolithic kernels and therefore Linux was, even in 1992, obsolete. Linux kernel developers Peter MacDonald, David S. Miller and Theodore Ts'o also joined the debate. The debate has sometimes been considered a flame war. While the debate initially started out as relatively moderate, with both parties involved making only banal statements about kernel design, it grew progressively more
V (operating system) modular windowing system for both local and remote applications. The little-known W Window System got its name because it was first hosted on the V operating system, and the better-known X Window System in turn got its name because its first version was based partly on W. V also spawned another pure microkernel effort at Apple Computer known as Vanguard, which added a number of improvements to the basic system. Vanguard later disappeared in a reorganization. The Tektronix VM700 television measurement instrument was developed in a networked V environment in the late 1980s and ran a lightly modified version of
