We set LC_ALL=C when sorting in a bin tool. This was done to make the result of using `sort(1)` consistent. Improved how the Primary files and Secondary files are sorted by `bin/output-index-inventory.sh` to sort with "-u -k 1n -k 3.2d". The above will change `index.html` files for all entries. Changed `bin/chk-entry.sh` VERSION from "1.1.2 2024-03-17" to "1.1.3 2024-03-18". Changed `bin/gen-authors.sh` VERSION from "1.3 2024-03-04" to "1.3.1 2024-03-18". Changed `bin/gen-location.sh` VERSION from "1.1 2024-03-04" to "1.1.1 2024-03-18". Changed `bin/gen-sitemap.sh` VERSION from "1.3 2024-03-16" to "1.3.1 2024-03-18". Changed `bin/output-index-inventory.sh` VERSION from "1.2 2024-02-27" to "1.2.1 2024-03-18". Changed `bin/pandoc-wrapper.sh` VERSION from "1.5 2024-03-18" to "1.5.1 2024-03-18". Changed `bin/sort.gitignore.sh` VERSION from "1.1.1 2024-02-23" to "1.1.2 2024-03-18". Changed `bin/tar-all.sh` VERSION from "1.1 2024-02-27" to "1.1.1 2024-03-18". Changed `bin/tar-year.sh` VERSION from "1.1 2024-02-27" to "1.1.1 2024-03-18". Performed `make www` to update all entry `index.html` files.

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||
<p><a href="https://en.wikipedia.org/wiki/WarGames">A strange game. The only winning move is not to
|
||
play</a>. No, really; you can’t
|
||
actually win. :)</p>
|
||
<p>The formatting really wants a wide screen; if you can’t read it that way, it’s
|
||
the standard “three triangles around a circular” logo for nukes.</p>
|
||
<p>This is a pretty straightforward game.</p>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<p>What this program does:</p>
|
||
<p>It plays <a href="https://en.wikipedia.org/wiki/Missile_Command">Missile Command</a>,
|
||
complete with MIRVs, smart bombs, extra cities, and scoring.</p>
|
||
<p>Command line arguments and input files are ignored.</p>
|
||
<p>To play, just point and click where you want your ABMs to explode.</p>
|
||
<p>The score is 10 points for each missile which is destroyed before
|
||
it reaches the ground, -1 point for each ABM used, and 100 bonus
|
||
points for each city left at the end of a level.</p>
|
||
<p>The game ends when you lose all your cities, although you will have
|
||
to wait until the level finishes raining down to see your final score.</p>
|
||
<h3 id="obfuscation">Obfuscation</h3>
|
||
<p>The main obfuscation technique is the need to compress the code to fit
|
||
all the functionality within the size limits. I could not have included
|
||
smart bombs without the rule excluding <code>{};</code> characters in the counts.
|
||
All of the <code>#define</code>s are there to reduce code size.</p>
|
||
<p>On the other hand, I did waste a few characters in order to include
|
||
some rather obfuscated math in the program. It uses fixed-point
|
||
arithmetic, resulting in the overuse of bitwise shift operators.
|
||
Another example is <code>(x|1)</code>, which is used in a couple different ways.
|
||
The purpose of <code>A/(x|1)</code> is probably obvious, but what does <code>(x|1)%2</code> do?</p>
