Remove hint.html and index.html
As per discussions on GitHub the index.html and hint.html files should be deleted in favour of README.md files (from any .text/.txt/.markdown/.md files which will be turned into README.md in an upcoming commit).

<h2>Judges' comments:</h2>
|

|

<h3>To build:</h3>
|
||||
|
||||
<pre><code>make dlowe
|
||||
</code></pre>
|
||||
|
||||
<h3>To run:</h3>
|
||||
|
||||
<pre><code>./dlowe [numbers...]
|
||||
</code></pre>
|
||||
|
||||
<h3>Try:</h3>
|
||||
|
||||
<pre><code>./dlowe 0 1 2 3 4 5 6 7
|
||||
./dlowe 16 32 64 128
|
||||
|
||||
echo sparkline of file sizes: `wc -c * | awk '{print $1}' | xargs ./dlowe`
|
||||
|
||||
./dlowe 0
|
||||
</code></pre>
|
||||
|
||||
<h3>Selected Judges Remarks:</h3>
|
||||
|
||||
<p>We liked how this entry used Unicode, specifically UTF-8, in a somewhat obfuscated way.</p>
|
||||
|
||||
<p>Also, why doesn’t it crash, and produces a correct output when called with one argument
|
||||
or when all arguments are equal?</p>
|
||||
|
||||
<p>For extra fun, compile and run</p>
|
||||
|
||||
<pre><code>#include <stdio.h>
|
||||
int main() {
|
||||
printf("%d %d %d\n", (int)(-1.0/0.0), (int)(0.0/0.0), (int)(1.0/0.0));
|
||||
}
|
||||
</code></pre>
|
||||
|
||||
<p>with gcc and clang.</p>
|
||||
|
||||
<p>With GCC (4.7.2), we get</p>
|
||||
|
||||
<pre><code>-2147483648 -2147483648 -2147483648
|
||||
</code></pre>
|
||||
|
||||
<p>and with clang (3.3), we get</p>
|
||||
|
||||
<pre><code>-2147483648 0 2147483647
|
||||
</code></pre>
|
||||
|
||||
<p>Which one is correct? :)</p>

<h1>sparkl</h1>
|
||||
|
||||
<p>A tiny implementation of command-line ‘sparkline’ data visualization.</p>
|
||||
|
||||
<h2>Synopsis</h2>
|
||||
|
||||
<pre><code>$ sparkl 0 1 2 3 4 5 6 7
|
||||
▁▂▃▄▅▆▇▉
|
||||
|
||||
$ echo sparkline of file lengths: `wc -c * | awk '{print $1}' | xargs sparkl`
|
||||
sparkline of file sizes: ▁▁▁▃▃▂▁▂▁▁▉
|
||||
</code></pre>
|
||||
|
||||
<h2>Description</h2>
|
||||
|
||||
<p>This is a handy little tool for visualizing numeric series from the
|
||||
command-line, using ‘sparklines’. Pass it a numeric series as arguments, and
|
||||
sparkl will display a sparkline graph, which you can use to very quickly get a
|
||||
sense of the shape of your data.</p>
|
||||
|
||||
<h2>Limitations</h2>
|
||||
|
||||
<ul>
|
||||
<li>Crashes with 0 arguments. It’d be trivial to fix, but adds a few bytes to the
|
||||
code.</li>
|
||||
<li>Produces bogus graphs when given > about 5000 arguments.</li>
|
||||
<li>Only works if your terminal is utf-8 and your font supports the 8 glyphs
|
||||
used.</li>
|
||||
<li>Produces a few harmless compiler warnings.</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<h2>Obfuscation</h2>
|
||||
|
||||
<p>The code is very terse. I was torn between submitting this version, and a
|
||||
one-line version compressed using a couple more -D flags.</p>
|
||||
|
||||
<p>Hand-rolled utf-8 sequence, magic numbers (what’s that 7 for?), meaningless
|
||||
variable names, reused variables, and so on.</p>
|
||||
|
||||
<h2>Acknowledgements</h2>
|
||||
|
||||
<p>Edward Tufte invented sparklines (among other things.) Brilliant.</p>
|
||||
|
||||
<p>Zach Holman’s <a href="https://github.com/holman/spark">‘spark’ utility</a> was absolutely
|
||||
an inspiration.</p>
|
||||
|
||||
<p>As I was writing up this description, I discovered I’m not the first person to
|
||||
write an obfuscated C sparkline utility! Vicent Martí created
|
||||
<a href="https://gist.github.com/vmg/1368661">this one</a> years (!) ago. (My
|
||||
implementation is completely independent.)</p>
