+Welcome at ralfj.de, my server for experiments and digital independence.
+On this machine I maintain several services which are part of modern life, and which I would rather not entrust to data krakens in some cloud (what if it's raining?):
+</p>
+<ul>
+ <li><a href="mailto:post-AT-ralfj-DOT-de">E-Mail</a>,</li>
+ <li>Jabber: My Jabber-ID is <a href="xmpp:ralf-AT-jabber-DOT-ralfj-DOT-de">ralf-AT-jabber-DOT-ralfj-DOT-de</a> (also see <a href="https://en.wikipedia.org/wiki/Extensible_Messaging_and_Presence_Protocol" target="_blank">the Wikipedia article about Jabber</a>),</li>
+ <li><a href="/git">Git repositories</a>,</li>
+ <li><a href="https://lists.ralfj.de/">Mailing lists</a>,</li>
+ <li>a DNS server (incl. DynDNS and DNSSEC),</li>
+ <li>and more.</li>
+</ul>
+<p>
+All software running on my server is of course <a href="https://en.wikipedia.org/wiki/Free_Software" target="_blank">free</a>.
+This is the only way for me to expect that it is not actually acting against my interests.
+Besides, all communication (if at all possible) is encrypted. This self-defense is seemingly necessary today to achieve freedom and basic rights (like privacy of telecommunications) in the digital world.<br>
+Speaking of which, my GPG key has the ID 0x1B24F3FF. You can download it <a href="0x1B24F3FF.asc">here</a> or on any <a href="https://sks-keyservers.net/" target="_blank">keyserver of the SKS network</a>.
+</p>
+<p>
+You may wonder why I spend so much time on this. Well, I already mentioned independence of the usual internet giants.
+Besides, it's lots of fun to have a closer look at the tools and service we all use daily, and understand how they function.
+Last not least, I learned a lot while setting up this server.
+If you have questions about this (or anything else on this server), please don't hesitate to <a href="mailto:post-AT-ralfj-DOT-de">mail</a> me!

+Use the menu at the left to browse this site for information about me and my projects. Maybe some of them are also of interest to you?

<h2>Willkommen</h2>
<p>
Willkommen auf ralfj.de, meinem Server für Experimente und digitale Unabhängigkeit.
Auf dieser Maschine laufen diverse Dienste, die zum modernen Alltag gehören, und die ich ungern Datenkraken in irgendwelchen Wolken anvertrauen möchte (was, wenn es regnet?):
+</p>
<ul>
<li><a href="mailto:post-ÄT-ralfj-PUNKT-de">E-Mail</a>,</li>
<li>Jabber: Meine Jabber-ID lautet <a href="xmpp:ralf-ÄT-jabber-PUNKT-ralfj-PUNKT-de">ralf-ÄT-jabber-PUNKT-ralfj-PUNKT-de</a> (siehe auch <a href="https://de.wikipedia.org/wiki/Extensible_Messaging_and_Presence_Protocol" target="_blank">den Wikipedia-Artikel zu Jabber</a>),</li>
<li>ein DNS-Server (inkl. DynDNS und DNSSEC),</li>
<li>und einiges mehr.</li>
</ul>
+<p>
Alle Software, die auf meinem Server läuft, ist selbstverständlich <a href="https://de.wikipedia.org/wiki/Freie_Software" target="_blank">frei</a>.
Nur so kann ich davon ausgehen, dass sie nicht gegen mich bzw. meine Interessen handelt.
Zudem läuft alle Kommunikation (soweit irgend möglich) verschlüsselt ab. Diese Art von Selbstverteidigung ist heutzutage offenbar nötig, um verbriefte Rechte (wie das Postgeheimnis) und unsere Freiheit auch im Internet durchzusetzen.<br>
<p>
Im Menü links findest du Informationen über mich bzw. was ich so tue.
Vielleicht ist manches davon ja auch für dich interessant.
