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>This is a nice quick <a
|
||
href="https://en.wikipedia.org/wiki/Histogram">histogram</a> plotter. A
|
||
useful utility when you need to look at the distribution of some
|
||
data.</p>
|
||
<h3 id="challenges">Challenges:</h3>
|
||
<p>You can modify the number of histogram <a
|
||
href="https://en.wikipedia.org/wiki/Data_binning">bins</a> and the
|
||
scaling of the histogram by editing the source. Try to find them!</p>
|
||
<p>If you look at the source you will notice that the usual array of
|
||
histogram bins is missing. The source contains no arrays and it does not
|
||
use <code>malloc(3)</code> or <code>alloca(3)</code>. How does it build
|
||
the histogram?</p>
|
||
<p>While the input does not need to be sorted, the histogram output is
|
||
sorted. How does it put the data into buckets? Why does it
|
||
<code>fork(2)</code> 22 times?</p>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<p>This small piece of program is meant to be a useful tool, when there
|
||
are some data around and you need a quick glance at the histogram. I am
|
||
all too often logged in to a remote machine with slow X connection, and
|
||
a terminal-based program would be of great help.</p>
|
||
<h3 id="limitations">Limitations</h3>
|
||
<ul>
|
||
<li>I optimized the output for the data I had around, you might want to
|
||
adjust for your needs. For a great excess of data points the program
|
||
will crash (depending on the available stack).</li>
|
||
<li>Giving too few (distinct) points can also cause crash (or division
|
||
by zero).</li>
|
||
<li>The program expects plain numbers separated by white spaces.</li>
|
||
<li>ASCII is assumed.</li>
|
||
<li>Some POSIX-like system is assumed (<code>fork()</code> and
|
||
<code>wait(NULL)</code> are used).</li>
|
||
<li>Do not give any arguments to the program.</li>
|
||
<li>Could rounding errors cause the omission of the highest bin? There
|
||
might be empty bins at the edges.</li>
|
||
</ul>
|
||
<h3 id="obfuscation">Obfuscation</h3>
|
||
<ul>
|
||
<li>The program follows a rather unconventional approach to the task of
|
||
histogram building. The usual array of integers (for the histogram bins)
|
||
is missing entirely. The data are read once, the range is determined,
|
||
but the data points are not put in any array. Yet they are remembered,
|
||
and each of them is put into its own bin afterwards. But where are the
|
||
bins?</li>
|
||
<li>I tried to use as few keywords as possible, hence there are no
|
||
loops.</li>
|
||
<li>Multi-process approach for optimal use of resources.</li>
|
||
<li>Some bin size obfuscation.</li>
|
||
</ul>
