Quotes[edit]

  • I had never engaged in remote multishrink psychoanalysis on this scale before, so it was a fascinating experience.
    • Ken Brown's Motivation, Release 1.2 [1].
  • Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.
    • Computer Networks, 3rd ed., p. 83. (paraphrasing Dr. Warren Jackson, Director, University of Toronto Computing Services (UTCS) circa 1985)
  • Fight Features. … The only way to make software secure, reliable, and fast is to make it small.
    • "Some Notes on the 'Who Wrote Linux' Kerfuffle", release 1.5 [2].
  • Many security texts decompose the security of an information system in three components: confidentiality, integrity, and availability. Together, they are often referred to as "CIA". [They] constitute the core security properties that we must protect against attackers and eavesdroppers—such as the (other) CIA.
    • Modern Operating Systems (with co-author Herbert Bos), 4th ed, p. 596
  • However, as every parent of a small child knows, converting a large object into small fragments is considerably easier than the reverse process.
    • Computer Networks, 4th ed., p. 428.
  • The nice thing about standards is that you have so many to choose from.
    • Computer Networks, 2nd ed., p. 254.
  • "He" should be read as "he or she" throughout the book.
    • Modern Operating Systems, 3rd ed., p. 2.
  • UNIX does not allow path names to be prefixed by a drive name or number; that would be precisely the kind of device dependence that operating systems ought to eliminate.
    • Modern Operating Systems, 3rd ed., p. 40.
  • System designers who do not allow users to type far ahead ought to be tarred and feathered, or worse yet, be forced to use their own system.

The "Linux is Obsolete" Debate[edit]

  • "Linux is a leprosy; …" This statement is not grammatically or factually correct.
    • Rebuttal to Ken Brown [3].
  • A lot of other people wanted a free production UNIX with lots of bells and whistles and wanted to convert MINIX into that. I was dragged along in the maelstrom for a while, but when Linux came along, I was actually relieved that I could go back to professoring.
    • Ken Brown's Motivation, Release 1.2 [4].
  • I really am not angry with Linus. Honest. He's not angry with me either.
    • Ken Brown's Motivation, Release 1.2 [5].
  • LINUX is obsolete.
    • In a Usenet message, 29 Jan 1992 [6].
  • The only real argument for monolithic systems was performance, and there is now enough evidence showing that microkernel systems can be just as fast as monolithic systems.
    • In a Usenet message, 29 Jan 1992.
  • But in all honesty, I would suggest that people who want a modern "free" OS look around for a microkernel-based, portable OS, like maybe GNU or something like that.
    • In a Usenet message, 29 Jan 1992.
  • Be thankful you are not my student. You would not get a high grade for such a design :-) […] Writing a new OS only for the 386 in 1991 gets you your second "F" for this term.
  • A multithreaded file system is only a performance hack.
  • Writing a portable OS is not much harder than a nonportable one, and all systems should be written with portability in mind these days.
    • In a Usenet message, 3 Feb 1992.
  • While most people can talk rationally about kernel design and portability, the issue of free-ness is 100% emotional.
    • In a Usenet message, 3 Feb 1992.
  • Will we soon see President Bush coming to Europe with Richard Stallman and Rick Rashid in tow, demanding that Europe import more American free software?
    • In a Usenet message, 3 Feb 1992.
  • If you just want to use the system, instead of hacking on its internals, you don't need source code.
    • In a Usenet message, 5 Feb 1992.
  • Microkernels are not a pipe dream. They represent proven technology.
    • In a Usenet message, 5 Feb 1992.
