XThe 1986 contest was named: "The Third International Obfuscated C Code Contest"
X
XThe rules for 1986 suggested categories due to the success of the 1985
Xjudging method. The maximum size was increased from 512 to 1024 bytes.
XLarry Bassel joined as the second official judge.
X
XA poll was taken for the worst code for BSD and System V program.
XThe Bourne Shell (/bin/sh) won for both systems. The BSD finger
Xprogram took third place.
X
XRules and results were posted to net.lang.c and net.unix-wizards.
XMicro/Systems Journal published started regular publishing of the winners.
XThe practice of making first announcement of the winners at the Summer
XUsenix BOF started this year. A notice was posted to net.announce.

XThis program computes a specific mathematical value. Simply compile
Xand give it an infinite amount of stack space and cpu time. Otherwise
Xjust be satisfied with the approximation displayed just before the core
Xdump.
X
XThis program will pass lint on your system assuming your lint is brave
Xenough to try and parse it correctly.

XSubject: Third International Obfuscated C Code Contest Rules
XNewsgroups: net.lang.c
XKeywords: rules,1986,obfuscate,contest
X
XGOAL: To write the most Obscure working C program following the rules below:
X
XRULES: 1) The source must be 1024 bytes or less. NO exceptions!
X
X 2) Include in your letter:
X a) Name (or anonymous), Company/School, City, State and Country.
X b) Your path from a major network site, if applicable.
X c) A brief statement of what the program should do.
X d) The Machine(s)/Operating system(s) on which it runs.
X e) Enclose your source between the following lines:
X ---start of program---
X <place obfuscated source of 1024 bytes or less here>
X ---end of program---
X
X 3) The entry should be written in common C. (K&R + common extensions)
X
X 4) The program must be of original work. All programs must be
X in the public domain. All copyrighted programs will be rejected.
X
X 5) Entries must be received between 31-Mar-86 and 30-May-86 0:00 GMT.
X Email your entries to:
X
X decwrl!nsc!obfuscate
X
X Entries sent by UUCP Email will be confirmed starting 1-May-86.
X People are encouraged to submit entries via Email, however one may
X mail entries the following address:
X
X International Obfuscated C Code Contest
X National Semiconductor
X Attn: Landon Noll Mail Stop: 7c266
X 1135 Kern Ave.
X Sunnyvale, CA 94086
X U.S.A.
X
XAWARDS: Winners of each category and the best of Show will be posted to
X net.announce as well as being published in the May 86 issue of the
X "Micro/Systems Journal". Winners also get to receive international
X fame/flame for their efforts!
X
XJUDGING: Awards will be given to the best entry in a number of categories.
X The actual category list will vary depending on the types of entries
X we receive. At the moment, we are considering using the following:
X
X * The most obscure algorithm
X * The worst abuse of the C preprocessor
X * The strangest source layout
X * The best small one line program
X * The most useful program
X * <anything else we need to give recognition to a good entry>
X
X Judging will be done by myself, Larry Bassel and other local people
X who are willing to help out.
X
X We will attempt to run each of them on a Vax 785/4.2BSD system.
X Don't let the lack of such a system stop you! Try to avoid operating
X system/machine specific code if you do not have such a system.
X Extra points will be given for programs which:
X
X a) pass lint without complaint
X b) do something quasi-interesting
X c) are portable
X
X A larger program size was selected to allow for a wider range of
X program ideas. However if you don't need 1024 bytes don't use them.
X Given two programs with similar techniques and similar levels of
X obfuscation, we will tend to favor the more concise entry.
X
XPOLL: We want to know what you think is the most poorly coded utility
X released with 4.xBSD and/or Sys V. The top results plus the
X best flames will be posted along with the contest results.
X To vote, please follow the guidelines below:
X
X 1) Include at the top of the letter:
X a) Name (or anonymous), Company/School, City, State and Country.
X b) Your path from a major network site, if applicable.
X c) the name of the poorly coded utility
X d) the name of the operating system on which it is found
X e) the line: <<<FLAME ON>>>
X f) up to 1024 bytes of flames
X g) the line: <<<FLAME OFF>>>
X
X 2) Confine your vote to the standard set of commands. I.e., don't
X flame about local commands or user contributed software.
X
X 3) Submit your votes via Email to:
X
X for 4.xBSD: decwrl!nsc!bsd_util
X for Sys V: decwrl!nsc!sysV_util
X
X or, you may send your votes by letter to the same address used by
X the contest. Please place your votes on different sheets of paper.
