In my experience, if you have to keep the lavatory door shut by extending your left leg, it's modern architecture. -- Nancy Banks Smith | |
Talking about music is like dancing about architecture. -- Laurie Anderson | |

It is a very humbling experience to make a multimillion-dollar mistake, but it is also very memorable. I vividly recall the night we decided how to organize the actual writing of external specifications for OS/360. The manager of architecture, the manager of control program implementation, and I were threshing out the plan, schedule, and division of responsibilities. The architecture manager had 10 good men. He asserted that they could write the specifications and do it right. It would take ten months, three more than the schedule allowed. The control program manager had 150 men. He asserted that they could prepare the specifications, with the architecture team coordinating; it would be well-done and practical, and he could do it on schedule. Furthermore, if the architecture team did it, his 150 men would sit twiddling their thumbs for ten months. To this the architecture manager responded that if I gave the control program team the responsibility, the result would not in fact be on time, but would also be three months late, and of much lower quality. I did, and it was. He was right on both counts. Moreover, the lack of conceptual integrity made the system far more costly to build and change, and I would estimate that it added a year to debugging time. -- Frederick Brooks Jr., "The Mythical Man Month" | |

***** Special AI Seminar (abstract) It has been widely recognized that AI programs require expert knowledge in order to perform well in complex domains. But knowledge alone is not sufficient for some applications; wisdom is needed as well. Accordingly, we have developed a new approach to artificial intelligence which we call "wisdom engineering". As a test of our ideas, we have written IMMANUEL, a wisdom based system for the task domain of western philosophical thought. IMMANUEL was supplied initially with 200 wisdom units which contained wisdom about such elementary concepts as mind, matter, being, nothingness, and so forth. IMMANUEL was then allowed to run freely, guided by the heuristic rules contained in its heterarchically organized meta wisdom base. IMMANUEL succeeded in rediscovering most of the important philosophical ideas developed in western culture over the course of the last 25 centuries, including those underlying Plato's theory of government, Kant's metaphysics, Nietzsche's theory of value, and Husserl's phenomenology. In this seminar, we will describe IMMANUEL's achievements and internal architecture. We will also briefly discuss our recent efforts to apply wisdom engineering to oil exploration. | |

"The net result is a system that is not only binary compatible with 4.3 BSD, but is even bug for bug compatible in almost all features." -- Avadit Tevanian, Jr., "Architecture-Independent Virtual Memory Management for Parallel and Distributed Environments: The Mach Approach" | |
"So I decided that if the architecture is fundamentally sane enough, say it follows some basic rules like it supported paging , then I would be able to say, yes, Linux fundamentally supports that model." -- Linus Torvalds on Portability (Open Sources, 1999 O'Reilly and Associates) | |
The relative speed of a computer, regardless of CPU architecture, is inversely proportional to the number of Microsoft products installed. -- From a Slashdot.org post | |
Because you want to win benchmarketing exercises, not demonstrate that your architecture has any value in the real world whatsoever. Because you know that you can induce people with financial approval to make stupid and irrational decisions based on irrelevant data. - Rodger Donaldson about benchmarking on linux-kernel | |
Hurd and architecture in one sentence? Uh-oh... - Al Viro on linux-kernel | |
indent does _not_ solve the problem of: * buggers who introduce wrappers for standard kernel stuff - like, say it, typedef int Int32; and sprinkle their crap with per-architecture ifdefs. - Alexander Viro on coding style |
