There are two ways to write error-free programs. Only the third one works. The personal computer market is about the same size as the total potato chip market. Next year it will be about half the size of the pet food market and is fast approaching the total worldwide sales of panty hose. - James Finke, President, Commodore International Ltd. (1982) Documentation is like sex: when it is good, it is very, very good; and when it is bad, it is better than nothing. - Dick Brandon A bad random number generator: 1, 1, 1, 1, 1, 4.33e+67, 1, 1, 1 A bug in the code is worth two in the documentation. A bug in the hand is better than one as yet undetected. A computer program does what you tell it to do, not what you want it to do. A computer scientist is someone who fixes things that aren't broken. A computer's attention span is only as long as its extension cord. A fault tolerant system must report the faults even as it tolerates them. A hacker does for love what others would not do for money. - Laura Creighton A list is only as strong as its weakest link. - Don Knuth A low level language is one whose programs require attention to the irrelevant. A paperless office has about as much chance as a paperless bathroom. A successful tool is used to do something undreamed of by its author. - Johnson A)bort, R)etry or S)elf-destruct? A)bort, R)etry, I)gnore, V)alium? A)bort, R)etry, I)nfluence with large hammer. AAAAAA - American Association Against Acronym Abuse Anonymous APATHY ERROR: Don't bother striking any key. ASCII to ASCII, DOS to DOS. Abstraction is achieved by data hiding and enforced by encapsulation. Adding manpower to a late software project makes it later. - Brook Advanced design: Upper management doesn't understand it. After a number of decimal places, nobody gives a damn. All computers run at the same speed...with the power off. All the simple programs have been written, and all the good names taken. All wiyht. Rho sritched mg kegtops awound? All you need to know is the user interface. - J. Redford An algorithm must be seen to be believed. - D. E. Knuth An elephant is a mouse with an operating system. And on the seventh day, He exited from append mode. Another megabytes the dust. Any given program will expand to fill available memory. Any nitwit can understand computers. Many do. - Ted Nelson Any program that runs right is obsolete. Any programming language is at its best before it is implemented and used. Any sufficiently advanced bug is indistinguishable from a feature. - Kulawiec Artificial Intelligence: Making computers behave like they do in the movies. As far as we know, our computer has never had an undetected error. - Weisert As of next week, passwords will be entered in Morse code. Asking if computers can think is like asking if submarines can swim. Asking whether machines can think is like asking whether submarines can swim. Avoid GOTOs completely if you can keep the program readable. Avoid temporary variables and strange women. Avoid the Fortran arithmetic IF (or better yet, just avoid Fortran). Avoid unnecessary branches. BASIC is to computer programming as QWERTY is to typing. - Seymour Papert BREAKFAST.COM halted... cereal port not responding! Backup not found! A)bort, R)etry or P)anic? Backup not found: A)bort, R)etry, M)assive heart failure? Bad command or file name. Go stand in the corner. Bad style destroys an otherwise superb program. Base 8 is just like base 10, if you are missing two fingers. - Tom Lehrer Be careful when a loop exits to the same place from side and bottom. Beware of programmers who carry screwdrivers. - Leonard Brandwein Brain fried; core dumped. Breakthrough: It finally booted on the first try. Breakthrough: It nearly booted on the first try. C:\BELFRY is where I keep my .BAT files. C:\GRAPHICS\GIF\NAUGHTY\FILTHY\DISGUSTING\WOW!

Try DEVICE=C:\EXOR.SYS Computer programmers do it byte by byte. Computers are a more fun way to do the same work you'd have to do without them. Computers are only human. Computers are unreliable, but humans are even more unreliable. - Gilb Computers are useless. They can only give you answers. - Pablo Picasso Computers talk to each other worse than their designers do. Computers... are not designed, as we are, for ambiguity. - Thomas Congratulations! You are the one-millionth user to log into our system. Controlling complexity is the essence of computer programming. - Kernigan Customer: A primitive life form at the bottom of the food chain. DYNAMIC LINKING ERROR: Your mistake is now everywhere. Debugger: A tool that substitutes afterthought for forethought. Design simplicity: It was developed on a shoe-string budget. Design: The activity of preparing for a design review. Diagnostics are the programs that run when nothing else will. Disc space, the final frontier! Disclaimer: Any errors in spelling, tact, or fact are transmission errors. Do files get embarrassed when they get unzipped? Do you like me for my brain or my baud? Document code? Why do you think they call it "code?" Don't comment or patch bad code; rewrite it. Don't compare floating point numbers solely for equality. Don't diddle code to make it faster; find a better algorithm. Don't document the program; program the document. Don't hit the keys so hard, it hurts. Don't let the computer bugs bite! Don't stop at one bug. Dreams are free, but you get soaked on the connect time. EBCDIC: Erase, Back up, Chew Disk, Ignite Card E Pluribus UNIX. Earth is 98% full...please delete anyone you can. Emacs is a nice operating system, but I prefer UNIX. - Tom Christiansen Error 13: Illegal brain function. Process terminated. Esc key to reboot Universe, or any other key to continue... Every bug you find is the last one. Every program in development at MIT expands until it can read mail. Every program is a part of some other program, and rarely fits. Every program is either trivial or it contains at least one bug. Everybody needs a little love sometime; stop hacking and fall in love! Exclusive: We're the only ones who have the documentation. Expert systems are built to embody the knowledge of human experts. - Kulawiec Field tested: Manufacturing doesn't have a test system. Finish your mail packet! Children are offline in India. Foolproof operation: All parameters are hard coded. Foolproof operation: All parameters are hard coded. From C:\*.* to shining C:\*.* Futuristic: It only runs on the next-generation supercomputer. Futuristic: It will only run on a next generation supercomputer. Gotta run, the cat's caught in the printer. Hackers have kernel knowledge. Hardware: The parts of a computer system that can be kicked. Help! I'm trapped in a Chinese computer factory! Hex dump: Where witches put used curses... Honey, I Formatted the Kid! Host System Not Responding, Probably Down. Do you want to wait? (Y/N) How an engineer writes a program: Start by debugging an empty file... How do I love thee? My accumulator overflows. How do I set my laser printer on stun? How was Thomas J. Watson buried? 9 edge down. I am a computer, dumber than any human and smarter than an administrator. I am still waiting for the advent of the computer science groupie. I am the computer your mother warned you about. I bet the human brain is a kludge. - Marvin Minsky I came, I saw, I deleted all your files. I do not fear computers. I fear the lack of them. - - Isaac Asimov I haven't lost my mind; it's backed up on tape somewhere. I just found the last bug. I modem, but they grew back. I must have slipped a disk; my pack hurts. I smell a wumpus. I suppose when it gets to that point, we shan't know how it does it. - Turing I used to have a life, then I got v32bis! I'm a modemer and I'm OK. I post all night and I sleep all day. I'm not a sysop, I just play one on the echoes. If I had it all to do over again, I'd spell creat with an "e". - Kernighan If a program is useful, it must be changed. If a program is useless, it must be documented. If a train station is where the train stops, what is a work station? If at first you don't succeed, call it version 1.0 If at first you don't succeed, you must be a programmer. If it was easy, the hardware people would take care of it. If only women came with pull-down menus and online help. If the code and the comments disagree, then both are probably wrong. - Schryer If you have a procedure with 10 parameters, you probably missed some. Implementation is the sincerest form of flattery. In /dev/null no one can hear you scream In computer science, we stand on each other's feet. - Brian Reid In the long run, every program becomes rococco, and then rubble. - Alan Perlis Is reading in the bathroom considered Multi-Tasking? It is easier to change the specification to fit the program than vice versa. It is easier to write an incorrect program than understand a correct one. It is now pitch dark. If you proceed, you will likely fall into a pit. It is ten o'clock; do you know where your processes are? It said, "Insert disk #3," but only two will fit! It wasn't as easy to get programs right as we had thought. - Wilkes, 1949 It's 10 o'clock. Do you know where your child processes are? It's here at last: We've released a 26-week project in 48 weeks. It's redundant! It's redundant! - R. E. Dundant Justify my text? I'm sorry but it has no excuse. Kiss your keyboard goodbye! Know Thy User. LISP: To call a spade a thpade. Last one out, turn off the computer! Let the machine do the dirty work. - Elements of Programming Style Life would be much easier if I had the source code. Life would be so much easier if we could just look at the source code. Lisp Users: Due to the holiday, there will be no garbage collection on Monday. Logic is neither an art or a science but a dodge. Logic: The art of being wrong with confidence... Long computations that yield zero are probably all for naught. MC Hammer, n. Device used to ensure firm seating of MicroChannel boards MIPS: Meaningless Indicator of Processor Speed. Machine independent code isn't. Machine-independent: Does not run on any existing machine. Maintenance free: It's impossible to fix. Maintenance-free: When it breaks, it can't be fixed... Make input easy to proofread. Make it right before you make it faster. Make sure all variables are initialized before use. Make sure comments and code agree. "Make sure your code ""does nothing"" gracefully." Managing programmers is like herding cats. Maniac: An early computer built by nuts... Manual Writer's Creed: Garbage in, gospel out. May the bugs of many programs nest on your hard drive. Maybe Computer Science should be in the College of Theology. - R. S. Barton Me and my two friends... GIF and Wesson. Meets quality standards: Compiles without errors. Meets quality standards: It compiles without errors. Memory dump: Amnesia... Microwave: Signal from a friendly micro... Modem: How a Southerner asks for seconds... Mommy! The cursor's winking at me! Multitasking: Screwing up several things at once... My BBS is baroque now. Please call Bach later with your Handel. My Go this amn keyboar oesn't have any 's. My computer NEVER cras My computer isn't that nervous, it's just a bit ANSI. My computer's sick. I think my modem is a carrier. My mail reader can beat up your mail reader. My sister opened a computer store in Hawaii. She sells C shells by the seashore. Netnews is like yelling, "Anyone want to buy a used car?" in a crowded theater. Never forget: 2 + 2 = 5 for extremely large values of 2. Never put off till run-time what you can do at compile-time. - D. Gries Never test for an error condition you don't know how to handle. - Steinbach Never trust a computer you can't lift. - Stan Masor Never trust a computer you can't throw out the window. - S. Hunt Never underestimate the bandwidth of a station wagon full of tapes. - Jackson Never violate the Prime Directory! C:\ Never write software that anthropomorphizes the machine. Never write software that patronizes the user. New: It comes in different colors from the previous version. Nice computers don't go down. No extensible language will be universal. - T. Cheatham No line available at 300 baud. No program done by a hacker will work unless he is on the system. No program done by an undergrad will work after she graduates. Nobody has ever, ever, EVER learned all of WordPerfect. Nostalgia: The good old days multiplied by a bad memory... Objects are closer than they appear. Old mail has arrived. Old programmers never die; they just branch to a new address. On a clear disk you can seek forever. - Computerworld Button On a clear disk you can seek forever. - Denning On a clear disk you can seek forever... One if by LAN, two if by C. - Paul Revere, as told by John Karwoski One man's constant is another man's variable. - Perlis One person's error is another person's data. One picture is worth 128K words. Overflow on /dev/null; please empty the bit bucket. People who deal with bits should expect to get bitten. - Jon Bentley Performance is easier to add than clarity. Performance proven: It works through beta test. Portable: Survives system reboot. Press [ESC] to detonate or any other key to explode. Printed on 100% recyclable phosphor. Profanity is the one language all programmers know best. Programmer: One who is too lacking in people skills to be a software engineer. Programmers do it bit by bit. Programming Department: Mistakes made while you wait. Programming is an art form that fights back. Programming is an unnatural act. Programming just with goto's is like swatting flies with a sledgehammer. Programs: What software used to be, back when we knew how to write it. Protect your software at all costs; all else is meat. Quality assurance: A way to ensure you never deliver shoddy goods accidentally. RAM DISK is not an installation procedure! REALITY.DAT not found. Atempting to restore Universe...... REALITY.SYS corrupted- reboot Universe (Y/N)? Random access is the optimum of the mass storages. Real programmers use: COPY CON PROGRAM.EXE Real programs don't eat cache. Remember the good old days, when CPU was singular? Remember, UNIX spelled backwards is XINU. Replace repetitive expressions by calls to a common function. Resistance is useless! (If < 1 ohm) Revolutionary: Disk drives go round and round. Revolutionary: The disk drives go round and round. SCCS, the source motel! Programs check in and never check out! - Ken Thompson SCCS, the source motel! Programs check in and never check out! - Ken Thompson SENILE.COM found... Out Of Memory. Satisfaction Guaranteed: We'll send you another copy if it fails. Save energy: Drive a smaller shell. Shift to the left! Shift to the right! Pop up, push down, byte, byte, byte! Software engineer: One who engineers others into writing the code for him/her. Software is best understood as a branch of movie making. - Ted Nelson Software is mind work. Having the right frame of mind is essential. Software is to computers as yeast is to dough. - Chuck Bradshaw Some programming languages manage to absorb change but withstand progress. Spellchecker not found. Press -- to continue ... Spelling checkers at maximum! Fire! Stack Error: Lost on a cluttered desk... Stack Overflow: Too many pancakes... Stack manipulation: The use of inflatable falsies. - -Datamazing, 4/1/78 State-of-the-art: What we could do with enough money. State-of-the-practice: What we can do with the money you have. Steinbach's Rule: Never test for an error condition you don't know how to handle Stock item: We shipped it once before, and we can do it again, probably. Structured Programming supports the law of the excluded muddle. Supercomputer: Turns CPU-bound problem into I/O-bound problem. - Ken Batcher Sure it's user-friendly...if you know what you're doing. Swap read error. You lose your mind. System going down at 1:45 for disk crashing. System going down at 5 pm to install scheduler bug. Systems programmers are the high priests of a low cult. - R. S. Barton Terminal glare: A look that kills... That does not compute. The Soviet Union does not exist any more in its present format. The attention span of a computer is only as long as its power cord. The best packed information most resembles random noise. The best way to accelerate a Mac is at 9.8 m / sec^2l. The computer is mightier than the pen, the sword, and usually, the programmer. The computer is the Proteus of machines. - Seymour Papert The computing field is always in need of new cliches. - Alan Perlis The determined programmer can write a FORTRAN program in any language. The generation of random numbers is too important to be left to chance. The generation of random numbers is too important to be left to chance. The less time planning, the more time programming. The moving cursor prints, and having printed, blinks on. The next generation of computers will have a "Warranty Expired" interrupt. The number of UNIX installations has grown to 10, with more expected. - June, 1972 The program is absolutely right; therefore the computer must be wrong. The program is absolutely right; therefore, the computer must be wrong. The programmer's national anthem is 'AAAAAAAAHHHHHHHH'. - Weinberg, p.152 The purpose of computing is insight, not numbers. - Hamming The steady state of disks is full. - Ken Thompson The value of a program is proportional to the weight of its output. The whole is the sum of its parts, plus one or more bugs The wise person writes bomb-proof code. The world is coming to an end... SAVE YOUR BUFFERS!! The world will end in 5 minutes. Please log out. The world's coming to an end. Log off and leave in an orderly fashion. There are always at least two ways to program the same thing. There are never any bugs you haven't found yet. There are two ways to write error-free programs; only the third one works. There can never be a computer language in which you cannot write a bad program. There is no problem that, when programmed just right, isn't more complicated. There must be more to life than compile-and-go. This BBS is ancient. Some say from the echocene. This fortune soaks up 47 times its own weight in excess memory. This login session: $13.76, but for you: $11.88. This message transmitted on 100% recycled electrons. This screen intentionally left blank. This system will self-destruct in five minutes. This time it will surely run. Those who can't write, write help files. Those who can, do. Those who cannot, teach. Those who cannot teach, HACK! Thrashing is just virtual crashing. To be, or not to be, those are the parameters. To define recursion, we must first define recursion. To err is human; to forgive, beyond the scope of the Operating System. To err is human; to really foul things up requires a computer. To iterate is human; to recurse, divine. To iterate is human; to recurse, divine. - Robert Heller To understand a program you must become both the machine and the program. Todays assembler command : EXOP Execute Operator Trojan: Storage device for replicating codes... Try not to let implementation details sneak into design documents. UNIX is a computer virus with a user interface. UNIX is many things to many people, but it has never been everything to anybody. USER ERROR: Replace user and press any key to continue. Unprecedented performance: Nothing ever ran this slow before. Unprecedented performance: Nothing ever ran this slow before. Use GOTOs only to implement a fundamental structure. Use IF...ELSE IF...ELSE IF...ELSE... to implement multi-way branches. Use free-form input where possible. User: A harmless drudge. Variables won't; constants aren't. - Osborn Virus detected! P)our chicken soup on motherboard? Volume in Drive C: TOO_LOUD! WOMAN.ZIP: Great Shareware, but be careful of viruses... WOMEN.ZIP: A great program, but it doesn't come with documentation... Was that your wife I saw in that GIF? Watch out for off-by-one errors. What do computer engineers use for birth control? Their personalities. What this country needs is a good five-cent microcomputer. When a program is being tested, it is too late to make design changes. When all else fails, let a = 7. If that doesn't help, then read the manual. When we write programs that "learn", it turns out we do and they don't. Where the system is concerned, you are not allowed to ask "Why?". Who is General Failure and why is he reading my disk? Why do we want intelligent terminals when there are so many stupid users? Years of development: We finally got one to work. You can't go home again, unless you set $HOME. You can't make a program without broken egos. You depend too much on computers for information. You don't have to know how the computer works, just how to work the computer. You forgot to do your backup 16 days ago. Tomorrow you will need that version. You forgot to do your backup 16 days ago. Tomorrow you'll need that version. You had mail, but the super-user read it, and deleted it! You have a tendency to feel you are superior to most computers. You have junk mail. You know it is going to be a bad day when you forget your new password. You might have mail. You never finish a program, you just stop working on it. Your e-mail has been returned due to insufficient voltage. Your fault, core dumped. Your password is pitifully obvious. ZAP! Process discontinued. Enter any 12-digit prime number to resume. ZMODEM: Big bits, Soft blocks, Tighter ASCII... [If you can't hear me, it's because I'm in parentheses] [Unix] is not necessarily evil, like OS/2. - Peter Norton f u cn rd ths, u cn gt a gd jb n cmptr prgrmmng. fortune: No such file or directory grep..grep..grep... (Frog with UNIX stuck in its' throat) The most likely way for the world to be destroyed, most experts agree, is by accident. That's where we come in; we're computer professionals. We cause accidents. - Nathaniel Borenstein There are two major products that come out of Berkeley: LSD and UNIX. We don't believe this to be a coincidence. - Jeremy S. Anderson If the automobile had followed the same development cycle as the computer, a Rolls-Royce would today cost $100, get a million miles per gallon, and explode once a year, killing everyone inside. - Robert X. Cringely The question of whether a computer can think is no more interesting than the question of whether a submarine can swim. - Edgar W. Dijkstra The only ""intuitive"" interface is the nipple. After that, it's all learned. Never trust a program unless you have the source. How should I know if it works? That's what Beta testers are for, I only coded it. If it aint broke, don't fix it! Our programs never have bugs, they just develop random features. ID10T ERROR! No decorations necessary. Dulce bellum inexpertis. JUST ROOTIN' AROUND. Common sense isn't. C'est la vie. I'm in shape ... round's a shape isn't it? ((wrong && wrong) != right) Quoth the Raven, "Eat My Shorts." "Said the fly, "Let us flee." Said the flea "Let us fly." Diplomacy is saying "nice doggy" until you find a rock. I just steal 'em, I don't explain 'em. Just My Opinion (But I'm Right!) Wanna giggle? Try (EDITOR=EDLIN !) in anything. Backup not found: (P) Panic (Any Other Key) Panic. Youth + confidence + myopia = naivete. Press -- to continue ... Buy a 486-33 you can reboot faster.. An appeaser feeds a crocodile, hoping to be eaten last. Success is just a matter of luck. Ask any failure. Irony: Giving father a billfold for Christmas. Every politician has a price, some hold bargain sales. The world is a beautiful book, for those who can read it. A person in a passion rides a mad horse. Hard work has a future payoff. Laziness pays off now. Celery raw develops a jaw. But stewed, is quietly chewed Where there is a stink feces there is the odor of being. A yawn is a silent shout. "A newspaper is a collection of half-injustices" If this is a battle, then you have already lost. "Every why hath a wherefore." An optimist is a guy without much experience... Life is not a spectacle or a feast, it is a predicament. A person is a lion in his own cause. Today has been a long year!!!!!!!!!! Any certainty is a delusion. "Beulah, peel me a grape." I sighed as a lover, I obeyed as a child. Every crowd has a silver lining. Old MacDonald had a computer with EIA I/O. Dammit Jim, I'm a doctor, not a tagline writer. Strange but not a stranger... He bellows like a cow standing on her tit. Good luck is a lazy man's estimate of a worker's success. Fiddle: Friction of a horse's tail on a cat's entrails. In this world a man must either be anvil or hammer. When you see a snake, never mind where he came from. Better to marry a man who loves you than one you love.
