Entry source is now prog.c for IOCCC years 2014 thru 2020, or is now dirname.c IOCCC years 1984 thru 2013. To achieve this state, we renamed the following: renamed: 2004/hibachi/src/hibachi.c -> 2004/hibachi/hibachi.c renamed: 2012/omoikane/nyaruko.alt.c -> 2012/omoikane/omoikane.alt.c renamed: 2012/omoikane/nyaruko.alt2.c -> 2012/omoikane/omoikane.alt2.c renamed: 2012/omoikane/nyaruko.c -> 2012/omoikane/omoikane.c renamed: 2012/omoikane/nyaruko.orig.c -> 2012/omoikane/omoikane.orig.c Modified `bin/subst.entry-index.sh` to add to entry `index.html` file, links to the `Makefile` and the _C code_ to the top navigation bar. Changed `bin/subst.entry-index.sh` VERSION from "1.2.2 2024-02-25" to "1.3 2024-03-02". Moved printing the Inventory link in the top navigation bar from `bin/subst.entry-navbar.awk` to `bin/subst.entry-index.sh`. Changed `bin/subst.entry-navbar.awk` VERSION from "1.0.1 2024-02-23" to "1.1 2024-03-02". Moved printing the Inventory link in the top navigation bar from `bin/subst.year-navbar.awk` to `bin/subst.year-index.sh`. Changed `bin/subst.year-index.sh` VERSION from "1.0 2024-02-11" to "1.1 2024-03-02". Changed `bin/subst.year-navbar.awk` VERSION from "1.0 2024-02-11" to "1.1 2024-03-02". Added location names (both default and common) to `author.html`. Changed `tmp/gen_author_json.sh` VERSION from "1.0 2023-06-06" to "1.1 2024-03-04". Added location names (both default and common) to `author.html`. Changed `bin/gen-authors.sh` VERSION from "1.2 2024-03-09" to "1.3 2024-03-04". The manifest and the resulting `.entry.json` files have been changed for `2004/hibachi` and `2012/omoikane`. The Makefiles for `2004/hibachi` and `2012/omoikane` copy the source file into the "previously used location". The `make clobber` rule removes the copied source. The `.gitignore` files have been updated accordingly. Improved how the concept of IOCCC terms _entry_, _author_ and _submission_ are used in markdown files. Links to markdown files (files ending in .md) within the repo were changed to link to HTML files (files ending in .html). Special cases where `README.md` became `index.html` were modified accordingly. Fixed URL for `bugs.html` in Makefile comments. Fixed name of `bin/sgi.sh` referenced in comments in `.gitignore` files. Links to locations within the repo are now relative. For example a link to `/contact.html` may become `../contact.html' or '../../contact.html` depending on the directory level of the markdown file. Nearly all links with absolute URLs under _https://www.ioccc.org_ or `https://ioccc-src.github.io/temp-test-ioccc_ have been changed to relative paths within the repo. Some exceptions to this (such as referring to a GitHub repo) were preserved. Fixed a number of inside `faq.md` and `bugs.md`. Added HTML name tags (in the form of an _entry_id_) for each entry referenced in `bugs.md`. Fixed links from outside of `bugs.html` into `bugs.html` accordingly. Where FAQ entries are referenced, a named tag is used so that if a FAQ is ever renumbered, links outside of `faq.html` will still work. Changed the _inventory_order_ of a compressed tarball from _300_ to _100000_. While this may have been done for the manifest, this changed had not yet been propagated into the `.entry.json` files. Links to web sites that were in the for <URL> are now [URL](URL). Performed `name www` to process all of the above. Improved format of `authors.html`. Full names are now bold. Location codes are now links back into `location.html` and location names (both default and common) are now italics. Added _author_handle_ each author. Changed `bin/gen-authors.sh` VERSION from "1.1 2024-02-25" to "1.2 2024-03-09". Improved format of `location.html` as location codes are now bold, author counts in a given location are now bold, and location names (both default and common) are now italics. Changed `bin/gen-location.sh` VERSION from "1.0.1 2024-02-23" to "1.1 2024-03-04". Added italic location name after location code in entry `index.html` files. Changed `bin/output-index-author.sh` VERSION from "1.4.1 2024-02-23" to "1.5 2024-03-04". Added _Location of authors_ to the sidebar as a link to `location.html`. TODO: While nearly all of the above mentioned changes are likely correct, they likely introduced a few errors that need correcting.
Twenty First 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.
The IOCCC has a web site and now has a number of international mirrors. The primary site can be found at www.ioccc.org.
Use make to compile entries. It is possible that on non-Unix / non-Linux
systems the Makefile needs to be changed. See the Makefile for details.
Read over the Makefile for compile/build issues. Your system may require certain changes (add or remove a library, add or remove a #define).
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.
Remarks on some of the entries
We believe you will be impressed with this year's winning entries. We had a very difficult time picking a single best from among the other entries because the overall quality of the submissions were so high.
This year we selected the top 4 entries for particularly high honors:
-
Gold award - Balanced use of obfuscation
A very extremely subtle and twisted piece of source code! Even if you start with the zeitak_deobfucate.c source, you will still have a very challenging time to understand it!
-
Silver award - Most elementary use of C
A fun program that could also have won "Best abuse of Ghostscript" because it managed to create some PDF files that Ghostscript could not read.
-
Bronze award - Best use of cocoa
A picture within a picture is worth more than a thousand (4 byte) words. :-)
-
Honorable mention - Most complex ASCII fluid
When you see this program in action, you too will very likely say wow as we did!
But don't ignore the other winning entries! There are games, utilities, eye candy, calculators and graphical tools to explore.
This year, Yusuke Endoh won with two entries, one of which (endoh1) won the special Honorable mention award. Eight of the winning entries were from people who won in previous years.
This year we had a number of authors from Asia. We saw our second authors from China and first from Korea. We are pleased to see outstanding entries from areas of the world that have not been active in past contests. Will we see an upswing of entries from South America, Africa and Antarctica next year? :-)
Please note that judging is done completely anonymously. Please do NOT reveal your identity in your source code. In the future we may disqualify entries that reveal the identity of the submitter!
There were some outstanding entries that did not win. Unfortunately some very good entries lost because they:
-
would take years to execute
-
were way way oversize and didn't even attempt to justify their excess by a clever abuse of the rules
-
obfuscate themselves by simply invoking a complex state machine
-
depend on a single obfuscation trick
-
could only be run on a particular vendor's platform
-
were very similar to previous winning entries
-
were based on an overused theme such as yet another fractal display program
-
didn't work as documented
We hope the authors of some of those entries will fix and re-submit them for the next IOCCC.
There is a risk in submitting an entry that is similar to a well used theme by previous winning entries. Previous entries set a very high bar. A new winning entry must not only compete against other submissions form the current year, they must also excel over similar winning entry in some particularly impressive way.
Final Comments
IMPORTANT NOTE: See contact.html for up to date contact details as well as details on how to provide fixes to any of the entries. See also the IOCCC FAQ for addition information on the IOCCC.
