build index.html for all winners

Browse Source 
Updated manifest as per recent file changes.

Updated winner `.winner.json` to reflect the manifest changes.

Added [bin/all_run.sh](bin/all_run.sh) tool to run a command over
all winning entries.

These tools had slight improvements in the help usage message:

* bin/gen-author.sh VERSION="1.3.1 2024-01-16"
* bin/gen-inventory.sh VERSION="1.0.1 2024-01-16"
* bin/pandoc_wrapper.sh VERSION="1.3.1 2024-01-16"
* bin/subst.default.sh VERSION="1.1.1 2024-01-16"
* bin/subst.winner-index.sh VERSION="1.1.1 2024-01-16"

The `bin/readme2index.sh` tool was improved so that
if the `index.html` file exists and the tool forms
the exact same content, then the file `index.html`
file is NOT touched.

* bin/readme2index.sh VERSION="1.1 2024-01-16"

We used the following command to generate `index.html` files
for all winning entries:

```sh
bin/all_run.sh -v 3 bin/readme2index.sh
```

NOTE: We have not (yet) built HTML files above the winner directory
level (e.g., no year level nor top level HTML), nor have be built
non-index HTML files for winners.

NOTE: By default we are running `pandoc(1)` with:

```
--fail-if-warnings=true
```

This means that any problems with markdown to HTML
generates an error.  This is done to be sure that
the HTML conversion is clean.

We had to fix the following `README.md` files:

* `2000/rince/README.md`

The reference [^2] was never used.  We made a guess that [^2] applies
to the same spot as [^1].  Perhaps there is a better spot where
[^2] applies?

NOTE: For every reference, there MUST be some place where that
reference is used.

* 2012/vik/README.md

The string "$...$" is assumed to be a TeX encoded string.

NOTE: Every "$..$" needs to be backslashed as in "\$..\$".

* 2018/burton1/README.md

The reference [2] was duplicated.  We changed the
second [2] to [3].

NOTE: Every reference needs to have a unique number.

* 2020/carlini/README.md

The string "$...$" is assumed to be a TeX encoded string.

NOTE: Every "$..$" needs to be backslashed as in "\$..\$".

We also found 2 errors in the `author/author_handle.json` file set:

* author/Anonymous_2001.json

The `author/Anonymous_2001.json` file was missing.

* author/Jari_Arkko.json

The winner ID for `1989_jar.1` had a typo.

<h2 id="judges-remarks">Judges’ remarks:</h2>
<p>Several IOCCC themes (<a
href="https://en.wikipedia.org/wiki/Reverse_Polish_notation">RPN
calculator</a>, animated <a
href="https://en.wikipedia.org/wiki/GIF">GIF</a> generator, <a
href="https://en.wikipedia.org/wiki/Ray_tracing_(graphics)">ray
tracing</a>) in one package! Very impressive!</p>
<p>The checkerboard pattern in the output can be broken. Could you
figure out how?</p>
<p>Larger GIF files confuse some image viewers.</p>
<h2 id="authors-remarks">Author’s remarks:</h2>
<h3 id="remarks">Remarks</h3>
<p>This program renders a generic <a
href="https://en.wikipedia.org/wiki/Reverse_Polish_notation">RPN</a>
expression in <a
href="https://en.wikipedia.org/wiki/Ray_tracing_(graphics)">ray-traced</a>
animated <a href="https://en.wikipedia.org/wiki/GIF">GIF</a> form. The
expression in spatial variables <code>x</code> and <code>y</code> is
specified on the command-line with the required resolution, and an
animated GIF showing a fly-around of the resulting surface is output to
<code>stdout</code>.</p>
<h3 id="usage">Usage</h3>
<p>The program should be run as:</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="ex">./blakely</span> xy<span class="pp">*</span> 32 <span class="op">&gt;</span> pic.gif</span></code></pre></div>
<p>where the first parameter is a <a
href="https://en.wikipedia.org/wiki/Reverse_Polish_notation">RPN</a>
expression, and the second is the width of the required <a
href="https://en.wikipedia.org/wiki/GIF">GIF</a>, up to a maximum of
250.</p>
<p>The expressions are written in <a
href="https://en.wikipedia.org/wiki/Reverse_Polish_notation">Reverse
Polish Notation</a> with the following characters recognised:</p>
<pre><code>+, -, *, / - usual arithmetic operations
^ - Exponentiation; valid for constant exponent only
s - sin
c - cos
0-9 - single digit integers
d - duplicate number on stack
t - transpose top two elements on stack
x - x coordinate value
y - y coordinate value</code></pre>
<p>NB: all arithmetic is done in double precision, so <code>23/</code>
is two-thirds, rather than 0.</p>
<p>The surface plotted corresponds to <code>-1 &lt;= x,y &lt;= 1</code>
and for best results, the generated <code>z</code> value should lie
between <code>-1</code> and <code>1</code>.</p>
<p>If there is a division by zero, square-root of a negative number, or
similar operation, then the results are undefined.</p>
<h3 id="examples">Examples</h3>
<p>For test-runs, use a resolution of 32. For simple expressions, the <a
href="https://en.wikipedia.org/wiki/GIF">GIF</a> generation should take
only a few seconds with a modern processor and full optimization.
Runtime scales as <a
href="https://en.wikipedia.org/wiki/Big_O_notation">O(N^3)</a> with
resolution <code>N</code>, and more complex expressions take longer to
compute. For example, increasing the resolution of
<code>ripple.gif</code> to 250 took ~35 minutes to render on an <a
href="https://en.wikipedia.org/wiki/Intel_Core#Core_i7">i7
processor</a>.</p>
<div class="sourceCode" id="cb7"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./blakely</span> xy<span class="pp">*</span> 32 <span class="op">&gt;</span> saddle.gif</span>
<span id="cb7-2"><a href="#cb7-2" aria-hidden="true" tabindex="-1"></a></span>
<span id="cb7-3"><a href="#cb7-3" aria-hidden="true" tabindex="-1"></a><span class="ex">./blakely</span> xx<span class="pp">*</span>yy<span class="pp">*</span>1++d5<span class="pp">*</span>ct/ 64 <span class="op">&gt;</span> ripple.gif</span></code></pre></div>
<h3 id="algorithm">Algorithm</h3>
<p>A generic root-finding algorithm to find the point of intersection
between a ray and the surface is done using a simple forward search from
the eye. In order to make the rendering realistic, both the value of the
expression, and its derivative with respect to <code>x</code> and
<code>y</code> must be tracked. This is done using an obvious
stack-based approach.</p>
<h3 id="obfuscations">Obfuscations</h3>
<p>Much of the obfuscation is achieved through the use of single-letter
variables and <code>#define</code>s. The characters output for the <a
href="https://en.wikipedia.org/wiki/GIF#File_format">GIF format</a> are
generated in myriad and wonderful ways, making use of <a
href="https://en.wikipedia.org/wiki/Exclusive_or">XOR</a>, return values
from <code>putchar()</code>, and odd expressions. The layout is in the
form of <code>X Y Z</code>.</p>
<h3 id="limitations">Limitations</h3>
<p>ASCII is assumed since many bytes for the <a
href="https://en.wikipedia.org/wiki/GIF">GIF</a> output are generated
from characters given in the source code. On compilation a few warnings
about parentheses come up when using gcc 4.6.3, and one about no return
value from <code>main()</code> (who uses exit codes anyway?), but clang
3.1 emits no warnings.</p>
<h3 id="questions">Questions</h3>
<ul>
<li>Apart from their appearance when computing the <a
href="https://en.wikipedia.org/wiki/Reverse_Polish_notation">RPN
expression</a>, <a
href="https://en.wikipedia.org/wiki/Sine_and_cosine">sin and cos</a> are
not used. How do we then get the correct angles for rotation?</li>
<li>Exactly how many times will the animation repeat?</li>
<li>Why is there an upper limit of 250x250 for the resolution?</li>
<li>What is the point of <code>b[0]</code>?</li>
<li>Where are the words <code>NETSCAPE</code> and <code>GIF</code>
hidden in the source?</li>
</ul>
<p>(Note that the author may or may not be able to answer all of the
above questions.)</p>
