Source Code For 22nd IOCCC Winners Has Been Released

Posted by Soulskill on from the go-small-or-go-home dept.

An anonymous reader writes "The source code for the 22nd International Obfuscated C Code Contest winners has finally been released. Many entries exploited bugs in the size check program, making the 2013 entries possibly the most featureful submissions ever."

  1. Perl by Threni · · Score: 5, Funny

    Is there one for Perl, but the other way around - where it's clear what the code is actually doing?

    I find this very impressive, not so much for the obfuscation, but for packing so much functionality into a small bit of code....

  4. It's amazing that they don't link to the source co by Anonymous Coward · · Score: 5, Insightful

    For a contest involving writing source code, it's astounding and infuriating that the judges did not link to the source code in the results.

  5. Ray tracer + web server + image encoder + clock by hydrofix · · Score: 5, Interesting

    I found this one a pretty mind-blowing entry. When compiled and run, it creates a web server at http://localhost:8224, which can be opened in a browser to display a ray-traced 3D scene of steel ball bearings on a checker-pattern surface, arranged to display the current time. Quoting the description:

    The program wears many hats (not literally). It is
    * a web server
    * a PNG encoder
    * a ray tracer
    * a clock

    Unlike the PC emulator entry, it does not require a binary blob and all the code and data fit within the 4 kilobyte limit.

    What did you expect? It's a contest for writing obfuscated code and you expect a webpage that has clear, concise information?
