The `display_as` field in an `.entry_json` file must match the regex `^[a-z][0-9a-z]*$` now. This is needed to reduce errors during the final round while converting a potential submission to entry form. Modify `1992/buzzard.2/.entry.json` and `1993/rince/.entry.json` to change `display_as` field to use lower case. Correct `2012/omoikane/.entry.json` to correctly reflect changes made by commit2955e5d07eand commit2955e5d07e. Change `bin/cvt-submission.sh` to verify that the `display_as` matches the above regex. Changed `bin/cvt-submission.sh` VERSION from "2.2.2 2025-06-30" to "2.3.0 2025-07-02". Rebuild all tarballs, both at the entry and the year level due recent changes to `var.mk`, `1337.mk`, and `ioccc.css`. Rebuild sitemap due to the changes above. Ran `make update` to test and perform the above.
First annual Obfuscated C Code Contest
In 1984, the first contest was held. The name of the
contest was simply "First annual Obfuscated C Code Contest".
View the index.html web page 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! This year we only had
remarks from two authors but these came years later.
Restrictions against machine dependent code were not in the rules in 1984. The source file size restriction was only 512 bytes. Rules and results were posted to net.lang.c and net.unix-wizards. The contest was announced in a net.lang.c post.
