Add preview of 1984-2019
The 2020 winners are hinted it, but the source code is not there,
nor are the hints. Someone could look into the HTML and
see what was commented out, but that is not a problem because
WHO won is known and the name of their AWARD is known already.
Moreover a number of the winners have talked about what their
entirs do, so the commented out spoiler text is not a bit problem.
One will find HTML commented out with:
<!-- XXX remove when 2020 is ready
2020 links here
XXX remove when 2020 is ready -->
The "XXX remove when 2020 is ready" string is found at the
start and end comment blocks. Again, soneone could read
what was commented out, but that is OK since most of that
information is known or can be known. The following files
have such HTML comment blocks in them.
./winners.html
./years-spoiler.html
./years.html
In addition, ./all/summary.txt was modified to not
include the 2020 entries for the momemt.
The 2020 winner code AND write-ups are NOT part of this set.
p.s. The all/all.tar.bz2 does not contain the 2020 source code (yet?).

In 1984, the first contest was held. The name of the contest was simply
|
||||
``Obfuscated C Code Contest''.
|
||||
|
||||
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.

that branches to the rest of the PDP code. On the Vax main is called with

the calls instruction which uses the first word of the subroutine as a

mask of registers to be saved. So on the Vax the first word can be anything.

The real Vax code starts with the second word. This small program

couldn’t! :-)</p>

mask of registers to be saved. So on the Vax the first word can be anything.
|

The real Vax code starts with the second word. This small program
|
||||
makes direct calls to the write() Unix system call to produce a
|
||||
message on the screen. Can you guess what is printed? We knew you
|
||||
couldn't! :-)

I'm sure you have all seen gross, or down right structurally obscene C
|
||||
source code before. Some people who deal with various parts of the
|
||||
UN*X source wonder if some folks try rather hard to produce such
|
||||
down right smelly code.
|
||||
|
||||
Now you have the chance to compete with the worst C hackers around
|
||||
by sending in your own obfuscated C program. Just follow the contest
|
||||
rules below:
|
||||
1) the source file must be no more than 512 bytes long
|
||||
|
||||
2) mail your source to: hplabs!nsc!chongo
|
||||
no later than April 11, 1984. entries posted to
|
||||
the net will NOT be accepted. please give your
|
||||
letter the subject of: obfuscated C code contest.
|
||||
|
||||
3) winning entries will be posted to net.lang.c after
|
||||
April 12, 1894. (thats the prize folks)
|
||||
|
||||
4) indicate your net address in the text of your
|
||||
entry, this will be used to give credit unless
|
||||
you indicate that you want to remain anonymous.
|
||||
|
||||
5) entries must be of original work. (dont send anything
|
||||
that might upset Big Brother Bell) all entries are
|
||||
public domain. (who would want to own them anyway?!)
|
||||
|
||||
Entries will be judged for: violations of structured programming, non-clarity,
|
||||
and use of "by the K&R book" C. (use of local mods to C are not encouraged)
|
||||
extra credit if they can be compiled using the 4.2BSD C compiler on our VAX 780,
|
||||
but dont let the lack of a 780 or 4.2 discourage you!
