    Isn't it called "Mandelbrot"?

    "Madelbrot" has a slightly different meaning in German :)

    Note from Alex: Ugh... fixed! I really should start writing these before 2AM...

  • squeamish ossifrage (unregistered)

    OK, I admit it, I've been known to stare into the cosmic wonder of the Mandlebrot Set while under the influence of a mind-numbing ... uh, margarita.

    But in this case I think it would be much more interesting to gaze into the depths of the brightly colored source code.

    The bar for entry into CodeSOD is pretty straight forward: professionally-developed code that elicits that certain What The— reaction.

    Is there really any point to censoring the phrase "What The Fuck" when everyone knows what "WTF" stands for anyway?

  • dkf (cs)

    This reminds me of when (many years ago now) we sent a postscript file to our brand-new 300dpi printer which computed and displayed the Mandelbrot set at maximum resolution, with all computations performed in the PS interpreter. I don't remember if it was an overnight job or an "over a long weekend" job, but it was definitely awesome...

    No, I don't have the code.

    In Austrian dialect, Mädel is maiden (Mädchen), and who knows, maybe there is some kind of bread made by maidens. Or maybe, if you put it into the context of the file "Hostel", bread made out of maidens...

    Just for fun I took the ispell 354984 word list and rot13'd it. then I checked how many encoded strings matched real words from the original list. Zero matches :( I am very disappointed. I expected at least 1% to encode into another valid string. I was amazed how quickly the following commands ran cat ROT13.LST | uniq -u > BIG.LST cat mword10/SINGLE.TXT | uniq -u >> BIG.LST cat BIG.LST | uniq --repeated > ROTRES.LST ROTRES.LST was empty, uniq -u removed any duplicates. echo owl >> test.file echo fox >> test.file echo owl >> test.file echo owl >> test.file cat test.file | uniq --repeated Gave the correct result "owl"

  • Smeagle (unregistered) in reply to tdittmar

    Depends on the region. Here in Bavaria, it's "Madel" for girl. So "Madelbrot" would be girlybread?

    TRWTF is that you made a screenshot out of plaintext you had on hand. Clearly you should have pasted it into Paint first, shot that, and pasted that into another imaging app, and included a shot of that.

    Doesn't "Mandel" mean tonsil? Back in the day we used to laugh about old tonsil bread and his set. Seriously.

    Courtesy of the great JoCo:

    Take a point called Z in the complex plane Let Z1 be Z squared plus C And Z2 is Z1 squared plus C And Z3 is Z2 squared plus C and so on If the series of Z's should always stay Close to Z and never trend away That point is in the Mandelbrot Set

    Mandelbrot Set you're a Rorschach Test on fire You're a day-glo pterodactyl You're a heart-shaped box of springs and wire You're one badass fucking fractal And you're just in time to save the day Sweeping all our fears away You can change the world in a tiny way

    I guess I thought that mentality had been put aside with the demise of the "Worse Than Failure" idiocy.

    Besides, people don't really think he actually changed the name because of his grandmother, do they?

    While everyone knows what it means, some of us appreciate the censorship so that it's a little less NSFW. You know, those of us who are grown up enough to actually have jobs? You'll get there someday, kid, if you're lucky.

    uniq expects the list to be sorted.

    From the man page:

    NAME
           uniq - report or omit repeated lines
    
    SYNOPSIS
           uniq [OPTION]... [INPUT [OUTPUT]]
    
    DESCRIPTION
           Discard all but one of successive identical lines from INPUT 
          (or standard input), writing to OUTPUT (or standard output).
    ...
    ...
    ...
    

    you should be using sort | uniq there.

    It stands for "Worse Than Failure". If you're filling in the other phrase, it's coming out of your own nasty mind. :D
