Every program has at least one bug and can be shortened by at least one instruction -- from which, by induction, one can deduce that every program can be reduced to one instruction which doesn't work. | |

As I argued in "Beloved Son", a book about my son Brian and the subject of religious communes and cults, one result of proper early instruction in the methods of rational thought will be to make sudden mindless conversions -- to anything -- less likely. Brian now realizes this and has, after eleven years, left the sect he was associated with. The problem is that once the untrained mind has made a formal commitment to a religious philosophy -- and it does not matter whether that philosophy is generally reasonable and high-minded or utterly bizarre and irrational -- the powers of reason are suprisingly ineffective in changing the believer's mind. - Steve Allen, comdeian, from an essay in the book "The Courage of Conviction", edited by Philip Berman | |
Technicality, n.: In an English court a man named Home was tried for slander in having accused a neighbor of murder. His exact words were: "Sir Thomas Holt hath taken a cleaver and stricken his cook upon the head, so that one side of his head fell on one shoulder and the other side upon the other shoulder." The defendant was acquitted by instruction of the court, the learned judges holding that the words did not charge murder, for they did not affirm the death of the cook, that being only an inference. -- Ambrose Bierce, "The Devil's Dictionary" | |
Experience is the worst teacher. It always gives the test first and the instruction afterward. | |
In California, Bill Honig, the Superintendent of Public Instruction, said he thought the general public should have a voice in defining what an excellent teacher should know. "I would not leave the definition of math," Dr. Honig said, "up to the mathematicians." -- The New York Times, October 22, 1985 | |
"No program is perfect," They said with a shrug. "The customer's happy-- What's one little bug?" But he was determined, Then change two, then three more, The others went home. As year followed year. He dug out the flow chart And strangers would comment, Deserted, alone. "Is that guy still here?" Night passed into morning. He died at the console The room was cluttered Of hunger and thirst With core dumps, source listings. Next day he was buried "I'm close," he muttered. Face down, nine edge first. Chain smoking, cold coffee, And his wife through her tears Logic, deduction. Accepted his fate. "I've got it!" he cried, Said "He's not really gone, "Just change one instruction." He's just working late." -- The Perfect Programmer | |
Ever feel like life was a game and you had the wrong instruction book? | |
I would suggest re-naming "rmbdd()". I _assume_ that "dd" stands for "data dependent", but quite frankly, "rmbdd" looks like the standard IBM "we lost every vowel ever invented" kind of assembly lanaguage to me. I'm sure that having programmed PPC assembly language, you find it very natural (IBM motto: "We found five vowels hiding in a corner, and we used them _all_ for the 'eieio' instruction so that we wouldn't have to use them anywhere else"). - Linus Torvalds on linux-kernel | |
(IBM motto: "We found five vowels hiding in a corner, and we used them _all_ for the 'eieio' instruction so that we wouldn't have to use them anywhere else"). [...] (IBM motto: "If you can't read our assembly language, you must be borderline dyslexic, and we don't want you to mess with it anyway"). [...] (IBM motto: "TEN vowels? Don't you know vowels are scrd?") - Linus Torvalds on linux-kernel | |
The Tao is forever undefined. Small though it is in the unformed state, it cannot be grasped. If kings and lords could harness it, The ten thousand things would come together And gentle rain fall. Men would need no more instruction and all things would take their course. Once the whole is divided, the parts need names. There are already enough names. One must know when to stop. Knowing when to stop averts trouble. Tao in the world is like a river flowing home to the sea. |
