She was happy. That’s most important. And she voluntarily gave me her smartphone and headphones when I delivered her the other week. So she really did a week of digital detox and like it. The weather was mostly good with just a few days of occasional rain. They did a lot of kayaking and hiking in the forests. Learned to read animal traces and crafted a bunch of stuff from natural materials. </p><p><strong>Summer camp II</strong></p><p>The other kiddo biked with the WWF team along the river Oder all the way up to Szczecin. Thats where I had to fetch him and bring him back to Berlin. Including my bike. And because he’s a newly discovered social animal he asked whether we can take two other participants with us back to Berlin. I don’t fully understand the physics of these Thule bike mounts for the tow hook. But it worked with three bikes. </p><p><strong><a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://falko.zurell.de/tag/project25/" target="_blank">#project25</a> update</strong></p><p>Fixed the garden faucets. Basically replaced the two old faucets with new ones. The old ones were leaking and couldn’t be fully closed anymore. So I bought two new ones and replaced them. Now we have water outside the house. </p><p>While rummaging around the garden I also found what looks like to be the old well. Will see whether that still has water. </p><p><strong>Webcam Templin</strong></p><p>The town got a live stream webcam now. Mounted on the tower of the Maria Magdalenen Kirch. Nice view: <a href="https://livespotting.tv/deutschland/templin/m55n7ph4" rel="nofollow noopener" target="_blank">https://livespotting.tv/deutschland/templin/m55n7ph4</a></p><p></p><p><strong>Red Kite</strong></p><p>Saw this impressive bird circling over my head this week. First thought it to be a bald eagle. Although a little too small. Asked my friend who actually raises eagles in our area here. He told me it’s “just” a red kite. And my friend @gemlog told me that apparently in the us the call of the bald eagle is often dubbed with that of the red kite. Because the <a href="https://xeno-canto.org/893195" rel="nofollow noopener" target="_blank">bald eagle’s call</a> doesn’t really sound bold :D. The <a href="https://www.british-birdsongs.uk/red-kite/" rel="nofollow noopener" target="_blank">red kite’s call</a> is what most of us probably associate with a bald eagle.</p><p><strong>Meshcore</strong></p><p>Played around with <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://falko.zurell.de/tag/meshcore/" target="_blank">#Meshcore</a> this week. <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://falko.zurell.de/tag/meshtastic/" target="_blank">#Meshtastic</a> and Meshcore represent two distinct approaches to LoRa mesh networking, each offering unique advantages for off-grid communication. While both platforms enable long-range, decentralized messaging without cellular infrastructure, their architectural differences and security models create important trade-offs for users.</p><p>Flashing the Meshcore firmware onto my Lilygo T-Echo and a Heltec V3 board was straightforward using their <a href="https://flasher.meshcore.co.uk" rel="nofollow noopener" target="_blank">web flasher</a>. </p><p><strong>Core Architectural Differences</strong></p><p><strong><a href="https://meshtastic.org" rel="nofollow noopener" target="_blank">Meshtastic</a></strong> operates as a true mesh network where every client device can route traffic for others, creating flexible communication paths through multiple hops. This approach maximizes coverage and connectivity but generates more network traffic as messages flood through the mesh. Meshtastic prioritizes accessibility with its open-source model, extensive community support, and user-friendly apps across platforms.</p><p><strong><a href="http://meshcore.co.uk" rel="nofollow noopener" target="_blank">Meshcore</a></strong>, by contrast, employs a more controlled architecture requiring dedicated repeater nodes for routing while limiting client-to-client communication to direct radio range. This design reduces network congestion and provides more predictable message delivery, but requires strategic repeater placement for optimal coverage. Meshcore emphasizes lightweight implementation and precise control over message routing and delivery confirmation.</p><p>Recent security research has exposed several critical vulnerabilities in Meshtastic that have heightened interest in alternatives like Meshcore. The most severe flaw, <strong><a href="https://cyberpress.org/severe-meshtastic-flaw/" rel="nofollow noopener" target="_blank">CVE-2025-52464</a></strong> with a CVSS score of 9.5, affected devices running firmware versions 2.5.0 through 2.6.10. This vulnerability stemmed from duplicated X25519 public/private key pairs and insufficient entropy during key generation.</p><p>Eventually I switched my device back to Meshtastic as there doesn’t seem to be any neighbouring nodes in my area. For Meshtastic I could at least find one in Templin.</p><p><strong>Debian Trixie Update </strong></p><p>Updated my old trusty Lenovo X220 to Debian 13 – Trixie. Also played around with different desktop managers and settled on MATE. </p><p>Tested “Tuba” Fediverse client and was surprised that it even handled the quirky Pixelfed Login properly. </p><p><strong>Pixelfed update</strong></p><p>speaking of the devil …. this week a new Pixelfed release and my automatic container update via Watchtower damaged <a href="https://pxl.mxhdr.net" rel="nofollow noopener" target="_blank">my Pixelfed</a> instance. </p><p>This was expected as Pixelfed is really a total mess to self-host. Again I had to manually intervene and trigger the database migrations manually to upgrade to the latest version and get my instance back working.</p><p>Now the Story feature works properly (from what I can tell) in the web interface and the native app on iOS. </p><p></p><p><a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://falko.zurell.de/tag/meshcore/" target="_blank">#Meshcore</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://falko.zurell.de/tag/meshtastic/" target="_blank">#meshtastic</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://falko.zurell.de/tag/project25/" target="_blank">#project25</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://falko.zurell.de/tag/uckermark/" target="_blank">#Uckermark</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://falko.zurell.de/tag/weekly/" target="_blank">#weekly</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://falko.zurell.de/tag/weeklyreview/" target="_blank">#weeklyreview</a></p>
