Added `bin/bin/tar-entry.sh` to build a compressed tarball for an entry. The compressed tarball is formed by gnu tar with options so that the same entry file content will always produce the same compressed tarball, byte for byte. As some files are missing from some entries, one should use the `-W` option as in: ```sh bin/tar-entry.sh -v 5 -W 2020/ferguson1 ``` Added `make form_entry_tarball` to the top level `Makefile` to build entry tarballs even when files are still missing. Added `make verify_entry_files` to verify that all entries have all of their files listed in their manifest, plus the top level ioccc.css and var.mk files. As file entry files are still missing (due to HTML files that need to be built), the overall `make quick_www` and `make www` do **NOT** (yet) exit when the `make verify_entry_files` fails. Improved `bin/chk-entry.sh` by removing some variables that were not needed. TODO: Improve `bin/` tool exit codes as the current use is a bit silly. TODO: Clean out some variables used in `bin/` tools as some of then are only set printed in debug statements. TODO: Clean up usage messages, some of the options listed to not match the `getopts(1)` parsing. In some cases the option needs to be parsed but needs to be ignored by the tool because another tool automatically passes along certain options that really have no effect. Such ignored options need to be show as "This option is ignored" in the usage message.
Fifteenth International Obfuscated C Code Contest
Standard IOCCC stuff
Look at the README.md file for the given winning entry for information 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.
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.
New Judge
The judges were unable to contact Jeremy Horn for judging the 2000 contest.
As a result, Simon Cooper: http://www.sfik.com/
joined our team. Simon is well known for being a co-author of the 2nd edition of the Building Internet Firewalls book.
Remarks on some of the entries
There were some outstanding entries that did not win. Unfortunately some very good entries lost because they:
- depended too much on non-portable side effects in expressions;
- depended too much on a particular byte order;
- required the use of a special script, data file or pseudo-machine language that was not supplied with the entry.
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 winners. The Best of Show is a fine example of compact obfuscation. But don't ignore the shorter winners. The Best Small Program, Best Abuse of User and Most Complete Program are well worth studying in detail.
The Worst Abuse of the Rules is technically allowed by the rules. We gave it an award this year, but don't assume you can get away with using it next time ... :-)
Speaking of time, be sure to check out the Astronomically Obfuscated and the Most Timely Output.
There was no 1999 contest
So what happened to 1999? Landon Curt Noll was scheduled to take a vacation from the IOCCC this year. The remaining judges were unable to contact Jeremy Horn, so the IOCCC stalled.
But thanks to Landon's returning early from his IOCCC vacation (Landon will take a full IOCCC vacation during some other year), Simon Cooper joining the IOCCC judging team as well as the hard work of Peter Seebach and Leonid A. Broukhis the judging was completed in Dec 2000.
It was decided that the 15th contest would be the year 2000 contest (the year the judging completed) rather than year 1999 (the initial scheduled start of the contest). That is why there is no 1999 contest.
