Winners of the 18th IOCCC

achowe writes "The winners of the 18th International Obfuscated C Code Contest have been announced. This years winners include a 'Commodore PET emulator', 'Sound generation with SDL audio', and a 'Text WWW Browser'."

No Source Code?

[geomon]

What's with that?

Seriously though, why post the results of a competition regarding obfuscated source code if we are unable to view the entries ourselves? Seem the announcement was a bit of a let down if all we get to see is a couple of output files from some of the entries.

Sigh... I miss the old days when awards announcements didn't have a trailer.

Maybe they are really available but are difficult to see? That would be the theme of the contest after all. Time to start digging through the html on the site!

RTFA. It quite clearly states that the source will be released later this year after the participants have been consulted.

Re:No Source Code?

[graveyhead]

WTF?

Right at the top of the page it says:

"The source code has not been released yet. The winners will be notified by EMail soon. They will be given a chance to review the write-up of their entry. Once this process is complete the source code will be made available on the winning entries web page. We anticipate that this will be in mid-December."

[jtorkbob]

True, they do propose a time at which they WILL give us the source, but it's still a nasty, nasty tease. I kind of expected to be able to see the code. "Free donuts in the break room." (minutes pass) "I see no donuts." "I didn't mean *right now*!"

[IdahoEv]

I can't wait until the code is out! I'm really excited by this one:

Most superfluous output

Francois Boutines - XML Voronoi diagrams generator
Toulouse, France

I've been wanting to write a voronoi generator for a game-map-development project (maps for a Risk clone). But I could only find mathematical definitions, not any good code that clearly laid out the algorithm. Hopefully this program will be nice and clear (and well-documented!) so that I can reproduce the algorithm from it.

This is the Interntional Obfuscated C Code Contest, not the Butt Ugly Perl Contest. How about:

Re:No Source Code?

[sethml]

Wikipedia has a pretty good entry on Voronoi diagrams [wikipedia.org].

And if you check out the image attached to the article [wikipedia.org], you'll find a remarkably obfuscated and short chunk of code to generate a random Voronoi diagram image. I bet this is the precursor to the winning code submitted to the IOCCC.

I love how on Slashdot a minor misunderstanding warrants the indignation of "WTF?" followed by an accusation of drug use.

I imagine in real life that you're much more pleasant. Perhaps in such a circumstance you would have said something along the lines of, "You may have missed that they will be releasing the source code, they just haven't done it yet."

I'm not one of the mods, but I'd like some if you're going to the pot store anyway.

Re:No Source Code?

[captain_craptacular]

I think you're the one smoking. Who cares that they announced their lameness at the top of the page? It's still utterly lame to announce the winners of an obscure coding challenge and not show the code.

Thats akin to the Academy Awards occuring for as yet unreleased movies. Which apparently is OK with you, as long as they tell you that you can't watch the movies for another month or two.

Re:No Source Code?

[redink1]

Obfuscation... You fear to go into those minds. The coders delved too greedily and too deep. You know what they awoke in the darkness of Programming... shadow and flame.

Source Code Published

[sr180]

The source code is usually published a month or two after the winners are announced. I dont know why, but this is typical.

Dont worry, most of us wont be able to read the source code anyway.

Re:Source Code Published

[QuantumG]

It's not source code. It's just code. "Source code" is defined as the prefered form of the program for making modifications. Obviously this aint it.

Re:Source Code Published

[grammar fascist]

It's not source code. It's just code. "Source code" is defined as the prefered form of the program for making modifications. Obviously this aint it.

Does this mean the authors can't release this code under the GPL?

Or would that disqualify way too much Perl?

Re:Source Code Published

[QuantumG]

That is my understanding yes. They could, obviously, but anyone who then distributed the obsfucated code could have someone demand the source code and they wouldn't be able to provide it. The owner of the copyright could then prohibit them from distributing the obsfucated code. Therefore the GPL would be providing no more protection than a proprietary license.

Re:Source Code Published

[makomk]

Let me let you in on a secret. For some entries (mine, for example), the obfuscated version *is* the preferred version for making modifications (yes, I knew how it worked *that* well; just don't ask me about it now). I'm not sure if everyone's is that way, but it could well be...

Well the judges of the IOCCC always make the announcements of the winners first to the public often at some event (this year it was the Vintage Computer Festival), then the judges notify the winners, soon after they send the winners the source tar ball with the judges' write-ups. The winners test the tar ball build process for their code and others, correct any serious mistakes with packaging, provide feedback on the comments, and sometimes they are allowed to correct serious bugs in their entries normally

Re:No Source Code?

[panth0r]

Let's think about this. These programmers aren't "jury-rig[ging]" code to work, they take a program that is relatively simple and make it as hard to read as possible. One of the points of the competition is to make your code difficult to read, which is a hard enough task to do, trust me. Reading obfuscated code is quite difficult, as I'm sure you would agree, but don't you think being able to both write and read obfuscated code might actually have some programming value?

Re:My favorite

[32Na]

Make v. 3.80 won't carry out the instructions for smr: instead it checks for a main method and gets hung when it doesn't find one! Perhaps the Makers of Make are learning from contests like this how to better handle special cases? (Or perhaps I don't know how to handle it properly...)

Re:My favorite

[WWWWolf]

I think Make just gets hung on pondering dependencies or something.

Anyway, the makefile for that entry just does something along the lines of "mv smr.c smr; chmod +x smr". It's an empty file. *NIXes have no problem executing empty files (producing nothing on stdout, so yes, it produces its own source), not sure about Windowses. =)

GCC doesn't seem to like this file - or actually, it *compiles* all right (with -c, it produces an object file with no problems), it just doesn't *link* the executable (undefin

Re:My favorite

[m50d]

I don't see how that one won, it's not a valid C program. It won't compile without -nostdlib, and if you do it segfaults when you try and run it, meaning you can't just feed its output into a c compiler and get another copy of it as you would expect. It's a clever idea and would work in, say, perl, but did they even test it?

Though I have though about how the writing process is. Do they like first write then program, then try to obfuscate the code. I can't be very easy to write a complex (well more or less) program directly obfuscated.

Perl, of course, is the ideal language for such a thing, and you would be looking for Acme::Smirch [cpan.org], which does a fabulous job of taking any perl script and producing a perfectly functional perl script that uses no alphanumeric characters or whitespace. The results of applying smirch to the smirch module are... well they're impossible to get past the lameness filter, but I think it is safe to say that it is fairly obfuscated.

One of my winning entries did something like that; because the judges would c-preprocess the file while judging it, I wrote the program in a high-level assembly language as macros, and let the c-preprocessor "compile" it to (obfuscated) two-opcode machine language inspired by the Analytical Engine.
