Renamed `ioccc.ico` to `favicon.ico`. Correctly added use of `favicon.ico` to all constructed HTML headers. Fixed the smart quote in HTML elements problem. Moved HTML "DO NOT EDIT" comments down below at the bottom of the HTML phase 1 section. According to to the Nu Html Checker, a charset attribute on a meta element found after the first 1024 bytes. Changed `bin/md2html.sh` VERSION from "1.1.3 2024-03-28" to "1.2 2024-03-30". Improved `bin/gen-status.sh` to adjust the "status_update" value only when the "contest_status" is changed. Performed a `make www` to perform and test the above under macOS.

||
<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||
<p>On many systems the compiler will not allow you to send the object file to
|
||
<code>/dev/tty</code>. The author suggested:</p>
|
||
<div class="sourceCode" id="cb5"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb5-1"><a href="#cb5-1" aria-hidden="true" tabindex="-1"></a><span class="fu">cc</span> <span class="at">-c</span> <span class="at">-o</span> /dev/tty jar.1.c</span></code></pre></div>
|
||
<p>As a last resort the <code>jar.1.sh</code> script provided simulates
|
||
writing the raw binary of the .o file to the terminal.</p>
|
||
<p>Abuse of the rules winning entry usually result in a change of the rules.
|
||
Starting in 1990, compiling entries must result an regular file
|
||
which can be executed.</p>
|
||
<p>Under certain conditions that are dependent on such diverse things such as:</p>
|
||
<ul>
|
||
<li>compiler type</li>
|
||
<li>compiler version</li>
|
||
<li>libc</li>
|
||
<li>crt0.o</li>
|
||
<li>operating system</li>
|
||
<li>terminal application</li>
|
||
<li>terminal driver</li>
|
||
<li>various bugs and misfeatures :-)</li>
|
||
</ul>
|
||
<p>the output of raw binary to a terminal can produce various effects
|
||
from the mildly annoying beeps to missing seeing the important
|
||
output, to various “ill effects” such as the crashing of the terminal
|
||
application. Instead we have opted to pipe raw binary thru the
|
||
strings utility before writing to standard output instead of
|
||
<code>/dev/tty</code>.</p>
|
||
<p>As a historical note, the Makefile does echo the original command
|
||
to standard output, the original shell command that once wrote raw
|
||
binary to the <code>/dev/tty</code> special file.</p>
|
||
<p>The use of piping raw binary thru stings makes the original 1989 output
|
||
more apparent, as was the case when using dumb CRT terminals (some
|
||
do dumb that they couldn’t even process simple ANSI escape sequences)
|
||
were more common.</p>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<p>This program is (supposedly) the smallest C program able to print “Hello
|
||
world.”. The compilation itself produces the desired printout and the program
|
||
need not be actually run.</p>
