Subject: 5th International Obfuscated C Code Contest Rules
Newsgroups: comp.lang.c,comp.unix.wizards
Keywords: rules,1988,obfuscate,contest

    Obfuscate:  tr.v.  -cated, -cating, -cates.  1. a.  To render obscure.
        b.  To darken.  2. To confuse:  his emotions obfuscated his
        judgement.  [LLat. obfuscare, to darken : ob(intensive) +
        Lat. fuscare, to darken < fuscus, dark.] -obfuscation n.
        obfuscatory adj.

GOALS OF THE CONTEST:

    * To write the most Obscure/Obfuscated C program under the rules below.
    * To show what should NOT be done in C programs.
    * To provide a safe forum for poor C code.  :-)

RULES:

    To help us handle the vast volume of entries, we ask that you
    follow the rules below.  Sorry for the length, but we need all
    the help we can get!

    1) Your source MUST be 1536 bytes or less, and it must be a complete
       program, not just a subroutine.  NOTE the new maximum size.

    2) To help us process your entries, we ask that you submit entries
       in the following format.  Please be sure to include the --- lines,
       otherwise our extraction program may skip your entry!

---header items---
name:        Your name, of course!
org:        School/Company/Organization
email address:    Email address from a well known site
postal address:    Postal address, include your country as well
environment:    Indicate the Hardware & OS under which your program was tested
entry:        A of B        <entry number such as 3 of 5, 1 of 1...>
remarks:            <see below>
---how to compile---
X Give the command(s) needed to compile your program.
X Follow the same rules as given for the program below except that the
X command size must be 160 characters or less.
---program---
X Place obfuscated source of 1536 characters or less in this section.
X Add a leading X to each line to avoid problems with mailers.
X Some mailers don't like files with very long lines.  If your entry contains C
C    lines longer 80 chars we ask you to form continuation line sets.  To form C
C    a continuation line set, place a 'C' character at the point of a split C
C    and place a C (instead of an X) at the beginning of the next line. C
C    Finally, end the continuation line set as normal.
X The C\nC's and leading X's will be removed prior to extraction and thus C
C    they don't contribute toward the source character count.  All other C
C    characters are considered to be source.
X Newlines count as 1 character.  Assume a standard 8 character tab stop.
---end---

    3) Regarding the header items:

        * Any text outside of the above format will be kept confidential.

        * All header lines are required, but you may use 'annonymous'
          for any header line other than 'remarks' or 'entry'.

        * In the 'remarks' please include:
        - what this program does
        - why you think the program is obfuscated
        - any other remarks you wish to make

    4) Your entry should be written in common C. (K&R + common extensions)
       Due to the lack of ANSI C compilers, it is suggested, but not
       required, that you avoid use of constructs unque to ANSI C.

    5) The program must be of original work.  All programs must be
       in the public domain.  All copyrighted programs will be rejected.

    6) Entries must be received between 15-Mar-88 0:00 GMT and
       25-May-88 0:00 GMT.  Email your entries to:

            ...!amdahl!obfuscate

       Amdahl talks to hplabs, decwrl, pyramid, sun, uunet, cbosgd, ...
       We will attempt to Email a confirmation of receipt of contest
       entries, however since Email is not reliable you may not receive it.
       People are strongly encouraged to submit entries via Email, however
       one may mail entries the following postal address:

        Landon Curt Noll
        Amdahl Corp.
        1250 E. Arques Ave.   M/S 316
        P.O. Box 3470
        Sunnyvale, CA
        94088-3470
        U.S.A.

      Write the words: "International Obfuscated C Code Contest" near the
      bottom left corner of the envelope.

    7) Each person may submit up to 8 entries.  Multiple entries must
       be sent in separate Email letters or postal envelopes.


ANNOUNCEMENT OF WINNERS:

    * First announcement will be at the Summer 88 Usenix BOF.

    * Winning entries will be posted to comp.sources.unix
      as well as news groups where these rules were posted
      in mid June 1988.  (depending on the judges work load ;-})

    * An article containing the winning entries will be published
      in a future issue of the "Micro/Systems Journal".

    * Winners receive international fame and flames!  :-)


JUDGING:

    Awards will be given to the best entry in a number of categories.
    The actual category list will vary depending on the types of entries
    we receive.  As a guide, consider using the following:

        * The best small one line program
        * The most obscure algorithm
        * The strangest source layout
        * The most useful obfuscated program
        * The most creatively obfuscated program
        * Best obfuscated entry smaller than 256 bytes
        * Best obfuscated entry smaller than 1024 bytes
        * <anything else so strange that it deserves an award>

POINTS TO PONDER:

    People are encouraged to examine winners of the previous contests.  A
    copy of these entries was posted to comp.sources.unix on or about
    15-Mar-88.  Contact the comp.sources.unix moderator, or some archive
    site if you missed that posting.  Keep in mind that rules change from
    year to year, so some winning entries may not be valid entries this
    year.  What was unique and novel one year might be 'old' the next
    year.  In short, use your best judgement.

    We examine each entry on several levels of confusion.  For example
    each entry is judged when we:

        * look at the original source
        * run it through;  sed -e ',^#[     ]*define,d' | /lib/cpp
        * run it through a C beautifier
        * examine the algorithm
        * compile and lint it
        * execute it

    One line programs are best when they are short, obscure and concise.

    We tend to dislike programs that:

        * are very hardware specific
        * are very OS or Un*x version specific
             (index/strchr differences are ok, but
              socket/streams specific code is likely not to be)
        * dump core or have compiler warnings
             (it is ok only if you warn us in the 'remark' header item)
        * won't compile under both BSD or SYS V Un*x
        * use an excessively long compile line to get around the
             size limit
        * are longer than they need to be
        * are similar to previous winners
        * are similar to previous losers  :-)

    Simply abusing #defines or -Dfoo=bar won't go as far as a program
    that is more well rounded in confusion.

    Unless you are crampt for space, or unless you are entering the
    'best one liner' category, we suggest that you format your program
    in a more creative way than simply forming excessively long lines.

    We like programs that:

        * are as concise and small as they need to be
        * do something quasi-interesting
        * pass lint without complaint
        * are portable
        * are unique or novel in their obfuscation style
        * use a number of different types of obfuscation
        * make us laugh and/or throw up  :-)

    Some types of programs can't excel in some areas.  We try to account
    for this by giving awards to programs in a number of areas.  Of course,
    your program doesn't have to excel in all areas, but doing well in a
    few helps.

    Be creative!

    The Judging will be done by Landon Noll and Larry Bassel.  If you have
    any QUESTIONS or COMMENTS, please feel free to send them to:

             ...!amdahl!judges

    however contest entries should be sent to:

            ...!amdahl!obfuscate
