<p>In my spare time, I currently develop two Android apps using <em>Flutter</em>: <a href="https://codeberg.org/PapaTutuWawa/anitrack">AniTrack</a>, a
simple anime and manga tracker based on my own needs, and <a href="https://moxxy.org">Moxxy</a>, a modern XMPP
client. While I don't provide release builds for AniTrack, I do for Moxxy. Those
are signed using the key-pair that Flutter generates. I thought to myself: "Wouldn't it be cool if I could keep
the key-pair on a separate device which does the signing for me?". The consequence
of this thought is that I bought a <em>YubiKey 5c</em>. However, as always, using it for my
purposes did not go without issues.</p>

<p>Hello everyone. Long time, no read.</p>
<p>In 2020, I published a post titled "<a href="https://blog.polynom.me/Running-Prosody-traefik.html">Running Prosody on Port 443 Behind traefik</a>", where I described how I run my XMPP server
behind the "application proxy" <a href="https://github.com/traefik/traefik"><em>traefik</em></a>.
I did this because I wanted to run my XMPP server <em>prosody</em> on port 443, so that the clients connected
to my server can bypass firewalls that only allow web traffic. While that approach worked,
over the last three years I changed my setup dramatically.</p>

<p><em>TL;DR</em>: This post also talks about the problems I faced while working on my logging. To log to
syslog from within my containers that do not support configuring a remote syslog server, I had
<em>syslog-ng</em> expose a unix domain socket and mounted it into the container to <code>/dev/log</code>.</p>

<p>I love static site generators. They are really cool pieces of software.
Give them some configuration files, maybe a bit of text and you receive
a blog or a homepage. Neat!</p>

<span class="text-md mt-2">Posted on 2020-01-03</span>

<span class="prose text-white mt-4">
<p>Roughly eight months ago, according to my hosting provider, I spun up my VM which
I use to this day to self-host my chat, my mail, my git and so on. At the beginning, I thought that
it would allow me both to get away from proprietary software and to learn Linux administration. While
my first goal was met without any problems, the second one I achieved in ways I did not anticipate.</p>

<p>About one year ago, I made plans to ditch many of the proprietary services that I used
on a daily basis and replace them with FOSS alternatives. Now it is a year later and
while my project is not done, I really did quite a lot.</p>

<p>In the first post of the series, I showed what information I gathered and what tricks can be used
to debug our mainline port of the <em>herolte</em> kernel. While I learned a lot just by preparing for
the actual porting, I was not able to actually get as close as to booting the kernel. I would have
liked to write about what I did to <em>actually</em> boot a <em>5.X.X</em> kernel on the device, but instead I will tell you
about the journey I completed thus far.</p>

<p>I love Linux. In fact, I love it so much that it runs on every computer I use, except for my phone but that
can be changed. It always amazes me how much control Linux gives me about my computer and how easy it is
to create a script that just does everything that I was doing manually before.</p>
