happy friday! :p

Lately I've been doing more #SelfHosting again due to the current situation. Of course, I'm paying particular attention to power consumption and noise. After good experiences with the #ARM64 architecture, even with power-hungry applications such as [Mastodon](https://fedifreu.de/about), I'm now using the smartphone technology for my homeservers, too.

There are #SBCs with more open hardware, but the #RaspberryPi is widely available, well documented, powerful and inexpensive. And it is available with up to 16 GB of RAM.

Anyone operating a server on the Internet must install #security updates quickly. However, many people forget to restart running software so that the new version runs instead of the old one. The #needrestart tool helps with this on Debian-based Linux systems, which unfortunately is usually not pre-installed.

On my Raspberry Pi 4, `needrestart` always runs correctly (automatically after `apt upgrade`). On my Raspberry Pi 5, however, I first had to create a configuration file as described by the main developer here:
https://github.com/liske/needrestart/blob/master/README.raspberry.md
Previously, the tool *always* claimed that a reboot was necessary because it thought an outdated Linux kernel was running.

Next, I want to activate #LUKS hard drive encryption on both raspis. Unfortunately, this is not as easy under #Raspbian or #RaspberryPiOS as on other Debian systems. If you have managed this: Please let me know how you did it!

In letzter Zeit mache ich aus gegebenem Anlass wieder mehr #SelfHosting. Natürlich achte ich dabei besonders auf den Stromverbrauch. Nach guten Erfahrungen mit der #ARM64-Architektur selbst bei leistungshungrigen Anwendungen wie Mastodon setze ich jetzt auch zuhause auf auf die aus Smartphones bekannte Technologie.

Es gibt zwar #SBCs mit offenerer Hardware, aber der #RaspberryPi ist überall erhältlich, gut dokumentiert, leistungsfähig und preiswert. Und es gibt ihn mit bis zu 16 GB RAM.

Wer einen Server am Internet betreibt, muss zügig #Sicherheitsupdates einspielen. Viele vergessen aber, laufende Software neuzustarten, damit die neue Version läuft statt der alten. Dabei hilft auf debianbasierten Linux-Systemen das Tool #needrestart, das leider meist nicht vorinstalliert ist.

Auf meinem Raspberry Pi 4 läuft needrestart schon immer korrekt (automatisch nach apt upgrade). Auf meinem Raspberry Pi 5 musste ich aber erst eine Konfigurationsdatei anlegen, wie es der Hauptentwickler hier beschreibt:
https://github.com/liske/needrestart/blob/master/README.raspberry.md
Bis dahin behauptete das Tool immer, dass ein reboot nötig sei, weil ein veralteter Linux-Kernel laufe.

Als nächstes will ich auf beiden Raspis die Festplattenverschlüsselung aktivieren. Das ist unter #Raspbian bzw. #RaspberryPiOS leider nicht so einfach wie auf anderen Debian-Systemen. Wenn ihr das geschafft habt: Schreibt gern eure Tipps!

#TIL: #RaspberryPi5 doesn't support #WakeOnLAN

So how am I supposed to reduce power consumption when not using our #LibreELEC setup on #RPi?

I do have Shelly Plug S available but I guess that I'd need a remote shutdown command before turning off power. Furthermore: how do I enable auto-boot when power resumes?

Any ideas?

Has anyone got #FreeBSD running on a #RaspberryPi5? If so, can you document how you got it working? I must be missing something.

Mini PCs rule!

This evening it is finally arrived the GMKtec Mini Computer Intel N97 12gen Alder Lake I ordered a couple of weeks ago.

Now I look forward to install #FreeBSD on it, and to taste that joy you feel when you erase #Windows from a brand new computer...

If you see at the dimensions, it is just slightly bigger than a #RPI2, while it is much more powerful than a #RPI5 and it came equipped with 12GB and 256GB SSD. Not bad!

It will replace my #LibreComputer #Renegade, which has served me very well so far, but now I need more power and the ability to work on a browser without hiccups...

If everything is going to work as I wish, I am going to release a new article about my (new) #ghostpc with this tiny computer running FreeBSD.

Beställt mer RPi-saker. Snart dags att bygga ett nytt RPi-kluster så fort väntans tider är över.

Dear fellow #raspberrypi tinkerers: I need your suggestions!

What is your killer setup for a #rpi5-based media server setup? (one where the pi is connected directly to the TV with a friendly GUI player)

For a few years now, I have been running a #rpi 4 setup with #OSMC and #Kodi (I have customised the underlying Debian setup with a few services).

But OSMC does not support #rpi5, and I could also happily do with a slightly less horrendously clunky player than Kodi (if that exists?)…
