The mobile About menu was missing the IOCCC markdown guidelines. This has been added to the mobile menu but moved to 'Status' which is where guidelines are (it has been renamed to be 'IOCCC Markdown Guidelines' to match the style of the other items in that menu). The About menu now has two more links, one for the website tools and the other for the include files of the tools. It might be, looking at the generated html files, better to have another menu instead, but what that should be is unclear. The reason it might be better is because the 'About' menu is rather long. In retrospect it might be better to not have the script include files in the html files but this can be decided and dealt with later. The script bin/find-missing-links.sh now ignores the directory NOTES/. A better approach might be using git ls-files --exclude but a quick test did not work right. Another option, at least for NOTES/, might be to use 'git ls-files --exclude-standard'. The bin/index.html file has been updated. Run make www to rebuild all html files.
Twentieth International Obfuscated C Code Contest
Standard IOCCC stuff
View the index.html web page for the given winning entry for information on how
on how to compile it and how to run the winning program.
Look at the winning source and try to figure how it does what it does!
You may then wish to look at the Author's remarks for even more details (this
year we included most of the information by the submitters).
Some ANSI C compilers are not quite as good as they should be. If yours is lacking, you may need to compile using gcc instead of your local compiler.
Historical note:
The IOCCC has a website and now has a number of international mirrors. The primary website can be found at www.ioccc.org.
Historical update:
The IOCCC website once had a number of international mirrors. As of 2020 Dec 29, GitHub serves as the distributed server farm for the IOCCC winner repo that GitHub renders as Official IOCCC web site - www.ioccc.org.
Remarks on some of the entries
There were some outstanding entries that did not win. Unfortunately some very good entries lost because they:
-
did not follow the "one program - one file" rule;
-
depended too much on 32 bit architectures;
-
were more of the "obfuscated math" kind rather than the "obfuscated C" kind.
We hope the authors of some of those entries will fix and re-submit them for the next IOCCC.
We believe you will be impressed with this year's winning entries. The Best of Show - Most Shrinkable is a fine example of character stitching. But don't ignore the other entries! There are games, puzzle solvers, utilities, eye candy, calculators and graphical and audio tools.
This year all authors are different, and there is a authors from a new country - China! Many authors won for the first time. (Please note that judging is done completely anonymously. Be warned that we may disqualify entries that reveal the identity of the submitter).
Final Comments
