+               <description>&lt;p&gt;A fun way to learn how to program
+&lt;a href=&quot;https://www.python.org/&quot;&gt;Python&lt;/a&gt; is to follow the
+instructions in the book
+&quot;&lt;a href=&quot;https://nostarch.com/programwithminecraft&quot;&gt;Learn to program
+with Minecraft&lt;/a&gt;&quot;, which introduces programming in Python to people
+who like to play with Minecraft.  The book uses a Python library to
+talk to a TCP/IP socket with an API accepting build instructions and
+providing information about the current players in a Minecraft world.
+The TCP/IP API was first created for the Minecraft implementation for
+Raspberry Pi, and has since been ported to some server versions of
+Minecraft.  The book contain recipes for those using Windows, MacOSX
+and Raspian.  But a little known fact is that you can follow the same
+recipes using the free software construction game
+&lt;a href=&quot;https://minetest.org/&quot;&gt;Minetest&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;There is &lt;a href=&quot;https://github.com/sprintingkiwi/pycraft_mod&quot;&gt;a
+Minetest module implementing the same API&lt;/a&gt;, making it possible to
+use the Python programs coded to talk to Minecraft with Minetest too.
+I
+&lt;a href=&quot;https://ftp-master.debian.org/new/minetest-mod-pycraft_0.20%2Bgit20180331.0376a0a%2Bdfsg-1.html&quot;&gt;uploaded
+this module&lt;/a&gt; to Debian two weeks ago, and as soon as it clears the
+FTP masters NEW queue, learning to program Python with Minetest on
+Debian will be a simple &#39;apt install&#39; away.  The Debian package is
+maintained as part of the Debian Games team, and
+&lt;a href=&quot;https://salsa.debian.org/games-team/unfinished/minetest-mod-pycraft&quot;&gt;the
+packaging rules&lt;/a&gt; are currently located under &#39;unfinished&#39; on
+Salsa.&lt;/p&gt;
+
+&lt;p&gt;You will most likely need to install several of the Minetest
+modules in Debian for the examples included with the library to work
+well, as there are several blocks used by the example scripts that are
+provided via modules in Minetest.  Without the required blocks, a
+simple stone block is used instead.  My initial testing with a analog
+clock did not get gold arms as instructed in the python library, but
+instead used stone arms.&lt;/p&gt;
+
+&lt;p&gt;I tried to find a way to add the API to the desktop version of
+Minecraft, but were unable to find any working recipes.  The
+&lt;a href=&quot;https://www.epiphanydigest.com/tag/minecraft-python-api/&quot;&gt;recipes&lt;/a&gt;
+I &lt;a href=&quot;https://github.com/kbsriram/mcpiapi&quot;&gt;found&lt;/a&gt; are only
+working with a standalone Minecraft server setup.  Are there any
+options to use with the normal desktop version?&lt;/p&gt;

-               <description>&lt;p&gt;A few days, I rescued a Windows victim over to Debian.  To try to
-rescue the remains, I helped set up automatic sync with Google Drive.
-I did not find any sensible Debian package handling this
-automatically, so I rebuild the grive2 source from
-&lt;a href=&quot;http://www.webupd8.org/&quot;&gt;the Ubuntu UPD8 PPA&lt;/a&gt; to do the
-task and added a autostart desktop entry and a small shell script to
-run in the background while the user is logged in to do the sync.
-Here is a sketch of the setup for future reference.&lt;/p&gt;
-
-&lt;p&gt;I first created &lt;tt&gt;~/googledrive&lt;/tt&gt;, entered the directory and
-ran &#39;&lt;tt&gt;grive -a&lt;/tt&gt;&#39; to authenticate the machine/user.  Next, I
-created a autostart hook in &lt;tt&gt;~/.config/autostart/grive.desktop&lt;/tt&gt;
-to start the sync when the user log in:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-[Desktop Entry]
-Name=Google drive autosync
-Type=Application
-Exec=/home/user/bin/grive-sync
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Finally, I wrote the &lt;tt&gt;~/bin/grive-sync&lt;/tt&gt; script to sync
-~/googledrive/ with the files in Google Drive.&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-#!/bin/sh
-set -e
-cd ~/
-cleanup() {
-    if [ &quot;$syncpid&quot; ] ; then
-        kill $syncpid
-    fi
-}
-trap cleanup EXIT INT QUIT
-/usr/lib/grive/grive-sync.sh listen googledrive 2&gt;&amp;1 | sed &quot;s%^%$0:%&quot; &amp;
-syncpdi=$!
-while true; do
-    if ! xhost &gt;/dev/null 2&gt;&amp;1 ; then
-        echo &quot;no DISPLAY, exiting as the user probably logged out&quot;
-        exit 1
-    fi
-    if [ ! -e /run/user/1000/grive-sync.sh_googledrive ] ; then
-        /usr/lib/grive/grive-sync.sh sync googledrive
-    fi
-    sleep 300
-done 2&gt;&amp;1 | sed &quot;s%^%$0:%&quot;
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Feel free to use the setup if you want.  It can be assumed to be
-GNU GPL v2 licensed (or any later version, at your leisure), but I
-doubt this code is possible to claim copyright on.&lt;/p&gt;
