 <p>The solution is adding another USB drive (2TB) with an encryption container (GELI) and a ZFS pool. The GELI encryption requires a secret key and a secret passphrase. I am updating the data to that drive once every three months (my calendar is reminding me about it), and afterwards, I keep that drive at a secret location outside of my apartment. All the information needed to decrypt (mounting the GELI container) is stored at another (secure) place. Key and passphrase are kept at different sites, though. Even if someone knew of it, he would not be able to decrypt it as some additional insider knowledge would be required as well.</p>
 <h2>Walking one round less</h2>
 <p>I am thinking of buying a second 2TB USB drive and setting it up the same way as the first one. So I could alternate the backups. One drive would be at the secret location, and the other drive would be at home. And these drives would swap place after each cycle. This would give some security about the failure of that drive, and I would have to go to the secret location only once (swapping the drives) instead of twice (picking that drive up to update the data + bringing it back to the remote location).</p>

 <p>I enhanced the procedure a bit. From now on, I have two external 2TB USB hard drives. Both are set up precisely the same way. To decrease the probability that both drives will not fail simultaneously, they are of different brands. One drive is kept at a secret location. The other one is held at home, right next to my HP MicroServer.</p>
 <p>Whenever I update the offsite backup, I am doing it to the drive, which is kept locally. Afterwards, I bring it to the secret location, swap the drives, and bring the other back home. This ensures that I will always have an offsite backup available at a different location than my home - even while updating one copy of it.</p>
 <p>Furthermore, I added scrubbing ("zpool scrub...") to the script. It ensures that the file system is consistent and that there are no bad blocks on the disk and the file system. To increase the reliability, I also run a "zfs set copies=2 zroot". That setting is also synchronized to the offsite ZFS pool. ZFS stores every data block to disk twice now. Yes, it consumes twice as much disk space, making it better fault-tolerant against hardware errors (e.g. only individual disk sectors going bad). </p>

 <p>How to overcome this? You need to take it further.</p>
 <h2>Taking it further</h2>
 <p>If you want to take it further, type "Object-Oriented Programming with ANSI-C" into your favourite internet search engine, you will find some crazy stuff. Some go as far as writing a C preprocessor in AWK, which takes some object-oriented pseudo-C and transforms it to plain C so that the C compiler can compile it to machine code. This is similar to how the C++ language had its origins.</p>

 <p>Have you reached this article already via Gemini? It requires a Gemini client; web browsers such as Firefox, Chrome, Safari, etc., don't support the Gemini protocol. The Gemini address of this site (or the address of this capsule as people say in Geminispace) is:</p>
-<a class="textlink" href="gemini://snonux.de">gemini://snonux.de</a><br />
+<a class="textlink" href="gemini://foo.surf">gemini://foo.surf</a><br />
 <p>However, if you still use HTTP, you are just surfing the fallback HTML version of this capsule. In that case, I suggest reading on what this is all about :-).</p>

 <p>Check out one of the following links for more information about Gemini. For example, you will find a FAQ that explains why the protocol is named Gemini. Many Gemini capsules are dual-hosted via Gemini and HTTP(S) so that people new to Gemini can sneak peek at the content with a regular web browser. Some people go as far as tri-hosting all their content via HTTP(S), Gemini and Gopher.</p>

 <h2>Conclusion</h2>
 <p>It was quite a lot of fun writing Gemtexter. It's a relatively small project, but given that I worked on that in my spare time once in a while, it kept me busy for several weeks. </p>
 <p>I finally revamped my personal internet site and started to blog again. I wanted the result to be exactly how it is now: A slightly retro-inspired internet site built for fun with unconventional tools. </p>

 <h2>Perl</h2>
 <p>Will I abandon my beloved Perl? Probably not. There are also some Perl scripts I use at work. But unfortunately I only have a limited amount of time and I have to use it wisely. I might look into Raku (formerly known as Perl 6) next year and use it for a personal pet project, who knows. :-). I also highly recommend reading the two Perl books "Modern Perl" and "Higher-Order Perl".</p>

 <h2>Conclusion</h2>
 <p>Should you be pedantic about open-source software? It depends. It depends on your fundamental values and how much time you are ready to invest. Open-source software is not just free as in money, but also free as in freedom. You will gain back complete control of your personal data. Unfortunately, installing ready proprietary apps from the Play Store is much more convenient than building up a trustworthy open-source-based infrastructure by yourself. As a guideline, use proprietary software and services with caution. Be mindful about your choices and where you leave your digital fingerprints. In doubt, think less is more. Do you really need this new shiny app? What benefit does it provide to you? Probably you don't really need that shiny new app.</p>
 <p>You have better chances when you know how to manage your own server and install and manage alternatives to the big cloud providers by yourself. I have the advantage that I have work experience as a Linux Systems Administrator here. I mentioned NextCloud already. I use NextCloud for online photo and file storage, contact and calendar sync and as an RSS news feed server. You could do the same with your own E-Mail server, you can also host your own website and blog. I also mentioned Matrix as a Skype alternative (which could also be an alternative to WhatsApp, Skype, Telegram, Viber, ...). I don't know a lot about Matrix yet, but it seems to be a very neat alternative. I am ready to invest time in it as one of my future personal pet projects. Not only because I think it's better, but also because for fun and as a hobby. But this doesn't mean that I invest *all* of my personal free time in it.</p>
