I'm gonna get my first cloud #VPS this week and this handy site (not affiliated) helped me choose the best provider and plan.

vps-prices.com

I chose #Hetzner; but I'm pending ID verification. I did some research and found lots of people getting rejected on Reddit... Hope I pass!

Will probably get #CAX11 #arm64 (2 VCPU, 4GB RAM, 40GB NVME, 20TB traffic) for $4.59USD/m to test some #selfhosted tools that require a 24/7 server as my home RPi server is not on all the time. #SelfHosting

We discussed truncating large disk images, OpenPower planning, a new ESXi release, Haiku, a long-term networking issue and its progress, #FreeBSD 15.0-RELEASE goals, uboot/squashfs/uboot under #ARM64, debugging with GDB and bhyve, joining Production User Calls with FreeBSD and Wayland, and more!

I'm writing an article on what kernel page size is, why you might want to use larger page sizes for certain applications, and how to do it. I'm interested in any feedback that #Arm64 users might have, or any experiences you can share: community.amperecomputing.com/

Ampere arm64 Developer Community · 64K Memory page sizes - any experiences to share?Hi all, I’m writing a fairly brief overview of the differences between 4K and 64K kernel page sizes - what a bigger kernel page size means, what types of applications benefit from larger contiguous chunks of memory, and how to use larger page sizes on various distributions. I’d love to hear feedback from anyone who has used larger page sizes, and whether they saw significant performance benefits for things like running VMs, databases, or AI inference workloads when running with 64K kernels - a...

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](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:
github.com/liske/needrestart/b
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:
github.com/liske/needrestart/b
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!

💻 FreeBSD Snapdragon X1E-78-100 💻

@dexter Revisiting the ThinkPad T14s Snapdragon with FreeBSD 15, here's where I left off. Do you know if there's been substantial momentum for the chipset (iirc, similar underlying requirements for your X13s)?

Two items stand out from my perspective, which may point to missing aspects in the "Fixed ACPI Description Table (FADT)", which should map the HPET .. hmmm..

1. No PSCI/SNCCC call function found
2. panic: No usable event timer found!

@crest this might be of interest?

From the original discussion months ago, some aspects from Linux World, specific to the X1E, which .. while not new-news etc etc you know where this goes... perhaps references something-something technical aspects. 😊 The T13s has almost full support for hardware enablement on 6.12/13 and branched.
