The Thirteen Greatest Error Messages of All Time

Technologizer writes "They add insult to injury — and computing wouldn't be the same without 'em. So I rounded up a baker's dozen of the most important error messages in computing history — from Does Not Compute to Abort, Retry, Fail to the Sad Mac to the big kahuna of them all — the mighty Blue Screen of Death. And just in case my judgment is off, I include a poll to let the rest of the world vote for the greatest error message of all." I can't believe that "I'm sorry Dave, I'm afraid I can't do that" didn't make the list.

  17. WebTV Anecdote "The Wrong Error Message" by Burning1 · · Score: 5, Funny

    The following story comes from Andy McFadden:

    The wrong error message

    In the late hours of September 17th, 1996, the day before the WebTV service was scheduled to go online, a group of us (Rick Daley, Lennart LÃvstrand, me (Andy McFadden), probably Arnold de Leon, plus several others I can't remember) had gathered in the operations center in 275 Alma St., Palo Alto. A collection of network operations and service software engineers were hanging around to bear witness to the official launch of WebTV.

    When the fated hour struck, one of the netops folks, Bryce Jasmer, started to go through the registration process with his WebTV box. As with any online service, we figured the good names would go quickly, so it was important to get in and register before The Masses signed up. Besides, there was something nifty about being one of the first people to ever sign up on the "real" service. Until this day, all accounts were "disposable" test accounts.

    A few of us were standing around, watching him type, feeling giddy with anticipation and lack of sleep. He'd entered his name, address, and other personal information, and was typing in his user name. This is the name used as the e-mail address. He typed in "jazz", so his e-mail would be "jazz@webtv.net". When he hit "enter" on the wireless keyboard, we heard the "whoom" sound that meant an error dialog was coming up. All eyes turned to the screen.

    ---

    To understand what happened next, it's important to understand a little something about how the service worked. WebTV was meant to be a family-oriented service, so it was important to screen all user names and other externally visible features for profanity. It's impossible to catch everything, but it's not hard to catch obvious things.

    The user names were compared against a set of regular expressions. Regular expressions allow you to match against a pattern. For example, "fu.*bar" would match against all names starting with "fu" and ending with "bar". With carefully-chosen patterns, you can catch and reject blatant instances while accepting words like "shitake" and "matsushita" that have a profane word embedded within them.

    The same mechanism was also used to prevent users from selecting "forbidden" names, such as "postmaster", "root", "admin", and "help". We had a text file that looked like this:

    admin.*
    User names may not start with "admin".
    postmaster
    You're not the postmaster.
    poop
    That's a bad word.
    weenie
    That's a bad word.

    An entry had two lines. The first was the regular expression to match, the second was the error message that would be displayed to the user. The service code read the file, grabbing two lines at a time, and when a user name was entered it compared the name against every regular expression. An error dialog was displayed for the first one that matched. If nothing matched, the user name was accepted.

    The code that read the file knew how to skip over comments. It did not, however, give any special treatment to blank lines.

    ---

    Someone had made some changes to the file with the profanity expressions, and while doing so had added a single blank line after the end of the "reserved" names and before the start of the profane words. When the code read the filter list, it grabbed the blank line as the regular expression, and the word that followed as the error message. As luck would have it, a blank-line regular expression matched anything.

    It's midnight. We're all a little punchy. Bryce types in a user name, and the box responds with a very simple message (click here to view).

    We start laughing hysterically.

  36. Explaining ARF by DragonHawk · · Score: 4, Informative

    I seem to remember a few times getting all four: Abort, Retry, Ignore, Fail. Ah, DOS.

    Yah. ARF came from the DOS "critical error" handler. Problems that required operator intervention were termed "critical errors", since the system could not proceed without help. When a BIOS or DOS system routine encountered such a problem, they invoked a software interrupt. The theory was that a good program could hook the interrupt and put in a more useful error handler. Obviously, not many programs did so.

    Abort killed the running program or command, and returned you to the DOS prompt. Retry had DOS try again, without returning control to the caller. Ignore meant control was returned to the calling routine, as if nothing had gone wrong. Fail meant control was returned to the running routine, with an error status indication.

    "Fail" might seem like a good idea, but it turns out that a lot of code didn't check the error status, leading to erratic behavior and/or just calling the same routine again.

    There was some rhyme or reason to when which choices were displayed when, but I've long since forgotten it. Some of it might have had something to do with some commands being internal to COMMAND.COM and some being external programs, but the service routines all invoking the same "critical error" software interrupt.

    I once wrote an "Eliza" like program in Basic....

    When I spotted a bug in the output I typed...
    list 1000-4000
    and my program responded...
    Really? Why?
    Totally derailed my train of thought.
