Changed the model of `status.json` model.
Updated `status.json` IOCCC_status_version from "0.2 2023-05-22"
to "1.0 2024-03-09".
Updated FAQ 2.6, improving how IOCCC entries announced.
Moved `bin/ioccc-status.sh` to `tmp/ioccc-status.sh`
now that we have a new status.json model for
which this tool no longer fits (sorry tm Canada 🇨🇦).
Added `status.md` markdown to explain the `status.json` model.
Added `status.html` to both display the contents of `status.json`
and render the contents of `status.md` as HTML.
Added `bin/status2html.sh` to convert `status.json`
into HTML for the `status.html` file.
Added `bin/gen-status.sh` to form `status.json`
and `status.html` files.
Added `make gen_status` to top level Makefile.
Performed `make www` to complete all of the above.

<h2 id="judges-remarks">Judges’ remarks:</h2>
|

<p>This entry confuses some C-preprocessors and some C-beautifiers. We
|

found one cpp that processed this source differently when it was read on
|
||
<code>stdin</code> instead of via <code>cc -E</code>.</p>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<h3 id="description">Description</h3>
|
||
<p>The following short program implements the “Yet Another” algorithm
|
||
for generating prime numbers. It will generate all primes up to
|
||
33554432, displaying them to the standard output as it churns along. As
|
||
33554432 is rather large on most machines, this code may take quite some
|
||
time to run to completion, so as an added feature, it will cease
|
||
execution upon reception of a signal (any will do equally well), as well
|
||
as in the event of a system shutdown or reboot.</p>
|
||
<h3 id="bugs">Bugs</h3>
|
||
<p>The alternative version (<a href="weisberg.alt.c">weisberg.alt.c</a>)
|
||
has never actually run to completion. After running for close to a week
|
||
it had reached somewhere around 250e6, when it became necessary to test
|
||
the reboot feature (which worked remarkably well). As there are quite a
|
||
lot of primes to be found before reaching <code>INT_MAX</code>, the
|
||
output produced can be quite overwhelming so it’s recommended to pipe
|
||
the output through your favorite pager (<code>more</code> or
|
||
<code>less</code>), and not output to a paper output device (unless you
|
||
have <em>LOTS</em> of paper).</p>
|
||
<h3 id="technical">Technical</h3>
|
||
<p>The original “Yet Another Prime Program” algorithm used here was
|
||
developed as a Computer Architecture course micro-programming exercise,
|
||
and was designed to take full advantage of the UR300 micro-architecture
|
||
to achieve blindingly fast speed. It was ported to C specifically for
|
||
the IOCCC. In the conversion/obfuscation step some of (much of) the
|
||
blazing speed was lost, but as a bonus, the understandability of the
|
||
code was reduced to zero.</p>
