Yesterday I’d done the heavy lifting of uphauling the #crux #rpi5 3.8 repo and right now I’m testing an update to kernel 6.12.28 which should be available soon as well. https://github.com/crux-arm/crux-ports-raspberrypi5-arm64 (check the 3.8 branch)

Zjistil jsem, že #HA na #Rpi5 nebliká. https://vhsky.cz/w/4YPgnxFpon4ZcP7CETLgNs
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, 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Previously, the tool always claimed that a reboot was necessary because it thought an outdated Linux kernel was running.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?
A question for #nextcloudpi and #nextcloud AI folks: would adding #hailo 8l to my #rpi5 offer any performance advantage?
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.
This is interesting: on the #rpi5 using a USB3.0 external drive, after #Jellyfin runs #ffmpeg on some files, or sometimes if a playback is interrupted and I try to resume, over in a terminal, unix filesystem tools cease to work until I cd off of the USB drive and then return. ls for example gives
ls: reading directory '.': Input/output error
If I do "pushd ~; popd", everything is fine again!
#JeffGeerling finally unlocks #RaspberryPi external #GPU support, and yes it runs Doom... 3 at 4K!
Raspberry Pi wizard Jeff Geerling has demonstrated 4K60 gaming on his #RPi5 setup. Crucially, the Pi 5 was given a considerable lift in the GPU department via the use of an M.2 to OCuLink adapter and an AMD Radeon RX 460 desktop graphics card
SuperTuxKart and Doom 3 can both run at 4K60 and max settings!

Another step in #homecloud! I had been using a Raspberry Pi4B, and I loaded it up, #Nextcloud, #Icecast2, #Wordpress, even never visited #Mobilizon, and it ran pretty good, no issues. Then I added #Pixelfed, and clearly it was straining, especially during overnight CRON jobs. So today I completed porting the works, not without hiccups and timely kind fedi- and forum help (opensource is cool!), to an #rpi5 that boasts twice the RAM and twice the speed!
And now I have a spare rpi4B
an #rpi5 question: if I take the 128G sd out of the 4B+ and boot a 5 with it, what are the chances it would "just work"? Like, how different could they be at the OS level? #famouslastwords

#RaspberryPi 5 patch boosts performance up to 18% via #NUMA emulation — #Geekbench tests reveal gains in both single and multi-threaded performance
According to #Linux kernel mainling list post "This series adds a very simple NUMA emulation implementation and enables selecting it on #arm64 platforms."
This improves #RaspberryPi5 single-core performance by 6% and multi-core performance by approximately 18%. These figures were determined using #Geekbench6 tests.
