Noll) Newsgroups: comp.lang.c,comp.sources.d,comp.unix.wizards,alt.sources,misc.misc Subject: 1991 International Obfuscated C Code Contest winners, 1 of 2 Message-ID: <20428@hoptoad.uucp> Date: 28 Aug 91 01:37:53 GMT Expires: 28 Nov 91 00:00:00 GMT Reply-To: chongo@hoptoad.UUCP (Landon C. Noll) Distribution: world Organization: Nebula Consultants in San Francisco Lines: 1632 Keywords: ioccc Enclosed is 1 of a 2 part shar file containing the winners of the 1991 International Obfuscated C Code Contest. First, we congratulate the winners for doing a fine job. Their efforts and feedback have resulted in a number of suggested changes for the 1992 contest. Second, we will be posting, sometime in early October 1991, a proposed set of rules for the 1992 contest. At that time, we will be requesting feedback on the proposed 1992 rules. Sometime later, perhaps in early November 1991, the official 1992 IOCCC rules will be posted. Last, we would like to make an apology to the 1991 winners and to the net for the delay in posting of these results. The poster of this article (chongo) went on vacation (Eclipse watching in Hawaii), held extended discussions with several of the contest winners, attempted to formulate the 1992 rules, and just plain ran out of time. We hope to avoid such delays in the future. If you find problems with some of the contest entries, or find typos in our notes, please send PATCH FILES containing the corrections to: judges@toad.com -or- ...!{sun,uunet,utzoo,pyramid}!hoptoad!judges chongo <Landon Curt Noll> /\cc/\ hoptoad!chongo Larry Bassel {uunet,ucbvax,cbosgd}|sun!lab p.s. previous winners are available on uunet.uu.net via anonymous ftp under the directory ~/pub/ioccc. The updated and corrected 1991 set will be deposited there when the 1992 rules are posted.

It is possible that Xon BSD or non-unix systems the makefile needs to be changed. X XLook at the source and try to figure out what the programs do, and run Xthem with various inputs. If you want to, look at the hints files for X(minor) spoilers. X XThis year, we did not single out an entry that was better than all of Xthe rest. We selected 3 entries that were, in our opinion, went beyond Xall of the other entries this year: X X Grand Prize by Brian Westley X Most Well Rounded by Diomidis Spinellis X Best Of Show by Daniel J. Bernstein X XName and address information are separated from the actual program Xprior to judging. This eliminates any chance that we would bias our Xjudging for/against any person or group. In the end, we are surprised Xas you are to see who as won. Even so, it is worth noting that XBrian Westley has submitted a winning entry for the past 5 years! X X XA few notes regarding possible changes to the contest: X XWe did not give awards to some traditional contest categories such as X"Best Layout" or "Worst Abuse of the Rules". We felt that to do so Xwould deny awards to more deserving entries. These categories have not Xbeen eliminated, and will likely be considered in future years. X XA number of entries made use of the following C pre-processor feature: X X #define X define X #X foo bar X XThis is not permitted under ANSI C. Some ANSI C compilers do allow Xthis. In the future, we do not want programs to use this feature. XBecause this request was not stated in the 1991 rules, we did not Xreject entries of this type. However we provided more portable Xversions so that more people could compile these programs. X XThis year we received entries that made use of the X Window System. XThis functionality is now available on many systems, we feel that Xprograms that use these are now portable enough to be valid entries. X XWe may allow programs to make use of the X Window System libs and include Xfiles, provided that they can operate with a system running at the level Xof at least X11r4. Requiring the use of imake, a specific window manager, Xspecific display hardware, or a specific user interface (Openl**k, XM*tif, ...) is likely not to be allowed. We will provide a more detailed Xexplanation of our viewpoint in next year's rules. X XIn order to encourage more 'normal' looking C programs, we are considering Xthe following change to the maximum size rule: X X Your source, not counting any <space>, <tab>, and a <newline> character, X and not counting any ';', '{' and '}' character followed by a <newline> X character, must be 1536 bytes or less. The entire source, counting all X characters, be 4096 bytes or less. X XSome thought has been given to adding some c++ categories, however this Xis not likely to happen soon. We are waiting until c++ compilers become Xcommon place on a wide number of systems. We also need time to brace Xourselves for what obfuscation c++ could wield! X XBe sure to wait until the 1992 rules are posted before submitting entries. XWe may fine tune the rules to reflect the some ideas above. X XPlease send us comments and suggestions what we have expressed above. XAlso include anything else that you would like to see in future contests. XSend such email to: X X ...!{sun,pacbell,uunet,pyramid}!hoptoad!judges X judges@toad.com X X XCredits: X XWe would like to thank Barbara Frezza for her role as official chef Xof the contest. Landon Noll appreciated the opportunity to serve Xas assistant pizza chef. Larry Bassel was official taste tester. Yummo!

X obfuscatory adj. X X XGOALS OF THE CONTEST: X X * To write the most Obscure/Obfuscated C program under the rules below. X * To show what should NOT be done in C programs. X * To provide a safe forum for poor C code. :-) X X XDEDICATION: X X The 1991 IOCCC is dedicated to the ANSI C pre-processor. X X XRULES: X X To help us handle the vast volume of entries, we ask that you follow the X rules below. SORRY FOR THE LENGTH, BUT WE NEED ALL THE HELP WE CAN GET! X X 1) Your source MUST be 1536 bytes or less. It must be a complete program. X X 2) To help us process your entries, we ask that you submit entries X in the following format. Please be sure to include ALL --- lines, X otherwise our extraction program may skip your entry! X X---header items--- Xname: Your name, of course! X Xorg: School/Company/Organization X Xemail address: Email address from a well known site, or in a registered domain X Xpostal address: Postal address X include your country as well X Xenvironment: Indicate the Hardware X and OS under which your program was tested X Xentry: 5 <i.e., entry number from 0 to 7 inclusive> X Xremark: Remarks about the program. See rule #3 below for details. X---how to ANSI compile--- XGive the command(s) needed to compile your program using an ANSI C Xcompiler. If your program should not be compiled under an ANSI C compiler, Xleave this section blank. The command size must be 160 characters or less. X---how to common compile--- XGive the command(s) needed to compile your program using an K&R/traditional XC compiler. If your program should not be compiled under a K&R style C, Xleave this section blank. The command size must be 160 characters or less. X---program--- XNot everyone has a program such as uuencode, and we don't want to blindly Xprocess a shar file, so we ask that you format your source as follows: X XAdd a leading X to EACH line, unless it is a split line. (see below) X XSome mailers don't like long lines. To be safe, split lines longer than 80 X characters. To split a line, place an E at the point of a split and X place a C (instead of an X) at the beginning of the next line. X XIf the program does not end in a newline, end the last line with an E. X XLeading X's, trailing E's followed by the two characters "\nC", and an E X at the last character of the last line are not considered to part of the X source and thus don't contribute toward the source character count. X Be careful with lines ending in "E\n", see the example below. X XNewlines and tabs each count as 1 character. Assume 8 character tab stops. X XThe newlines here were placed for reasons of readability. In your entry, X every line in this section must begin with either an X or a C. X XExample: X XXThis is a single line containing 79 E XCcharacters including the E XCfinal newline. XXThe next line contains only a single newline. XX XXThis line is terminated by a newline preceded by an EE XC XXThis last line is not terminated by a newline and ends in an EE X---end--- X X 3) Regarding the header items: X X * Any text outside of the above format will be kept confidential. X X * All header lines are required, but you may use 'anonymous' X for any header line other than 'remarks' or 'entry'. X X * Only the '---program---' section uses the 'X', 'C', 'E' notation. X X * In the 'remark' item, please include: X - what this program does X - why you think the program is obfuscated X - any other remarks (humorous or otherwise) X - By default, we will select your program source and/or binary X filename. If your entry REQUIRES a specific source and/or X binary filename, please say so in the remark section. X - If this entry is a re-submission of a previous entry. X X 4) Your entry should be written in common C (K&R + common extensions) X or ANSI C. If your program will NOT compile under an ANSI C or X K&R C compiler, leave the particular 'how to' section blank. X If you leave a 'how to' section blank, include the '---' line. X X You do not have to fill in both 'how to' sections, though you must X fill in at least one 'how to' section. If you leave a 'how to' X section blank, include the '---' line anyway. X X 5) The program must be of original work. All programs must be X in the public domain. All copyrighted programs will be rejected. X X 6) Entries must be received between 06-Mar-91 0:00 UTC and X 16-May-91 0:00 UTC. Email your entries the address found below. X (UTC is essentially equivalent to Greenwich Mean Time) X X We will attempt to Email a confirmation of receipt of contest X entries, however since Email is not reliable you may not receive it. X We regret that we can no longer accept entries via postal mail. X X 7) Each person may submit up to 8 entries. Only 1 entry per Email X letter. If you submit multiple entries, be sure that each has a X unique entry number. X X We will discard all but the latest email in the case of multiple X entries with the same entry number. Thus, if you wish to correct X a previously sent entry, re-send it with the same entry number. X Just to be sure email does not arrive out or sequence, note that X fact in the 'remark' item. X X 8) Entries requiring human interaction to be built are not allowed. X (for example, don't use #include "/dev/tty") X X 9) Compiling an entry must result a regular file which may be executed. X (for example, don't use -o /dev/tty) X X XANNOUNCEMENT OF WINNERS: X X * First announcement will likely be at the Summer 91 Usenix conference. X X * Winning entries will be posted in mid June 1991 to X comp.sources.unix as well as news groups where these rules X were posted. (depending on the judges work load) X X * Winning entries will be deposited into the uunet archives. X X * An article containing the winning entries will be published X in a future issue of the "Micro/Systems Journal". X X * Winners receive international fame and flames! :-) X X XJUDGING: X X 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. As a guide, consider using the following: X X * The best small one line program X * The strangest source layout X * The most useful obfuscated program X * The most creatively obfuscated program X * Best obfuscated entry smaller than 256 bytes X * Best obfuscated entry smaller than 1024 bytes X * Best abuse of ANSI C X * Worse abuse of the rules (no abuse of entry format please!) X * <anything else so strange that it deserves an award> X X XPOINTS TO PONDER: X X People are encouraged to examine winners of the previous contests. X A copy of these entries has been posted to comp.sources.unix. X Contact the comp.sources.unix moderator, or some archive site (such X as uunet). Keep in mind that rules change from year to year, so some X winning entries may not be valid entries this year. What was unique X and novel one year might be 'old' the next year. X X We examine each entry on several levels of confusion. For example X each entry is judged when we: X X * look at the original source X * If it is ANSI, convert tri-graphs to ASCII X * C pre-process the source ignoring '#include' '#define' lines X * C pre-process the source ignoring '#define' and '#include' lines X * run it through a C beautifier X * examine the algorithm X * lint it X * compile it X * execute it X X One line programs are best when they are short, obscure and concise. X X We tend to dislike programs that: X X * are very hardware specific X * are very OS or Un*x version specific X (index/strchr differences are ok, but socket/streams specific X code is likely not to be) X * dump core or have compiler warnings X (it is ok only if you warn us in the 'remark' header item) X * won't compile under both BSD or SYS V Un*x X * use an excessively long compile line to get around the size limit X * obfuscate by excessive use of ANSI tri-graphs X * are longer than they need to be X * are similar to previous winners X * are similar to previous losers :-) X X Simply abusing #defines or -Dfoo=bar won't go as far as a program X that is more well rounded in confusion. X X Unless you are cramped for space, or unless you are entering the X 'best one liner' category, we suggest that you format your program X in a more creative way than simply forming excessively long lines. X X We like programs that: X X * are as concise and small as they need to be X * do something at least quasi-interesting X * pass lint without complaint (not a requirement, but it is nice) X * are portable X * are unique or novel in their obfuscation style X * MAKE USE OF A NUMBER OF DIFFERENT TYPES OF OBFUSCATION X * make us laugh and/or throw up :-) X X Some types of programs can't excel in some areas. Of course, your X program doesn't have to excel in all areas, but doing well in several X areas really does help. A humorous note in the remark section helps. X X Be creative!
