FreeBSD 15.0-RELEASE-p3 on ARM64 in QEMU:

― SDDM, pictured, is barely usable.

After login to Plasma (X11), resolution is limited to 800 x 600.

How can I avoid the issue with SDDM?

Host: Kubuntu 25.10, Virtual Machine Manager with Ramfb for video. Guest: non-base packages from the latest repos.

Not reproducible with FreeBSD 16.0-CURRENT on ARM64 in QEMU on the same host.

[Перевод] Оптимизация Java-приложений для Arm64 в облаке

JVM в облаке часто экономит память и CPU по дефолту, из-за чего Spring-сервис использует меньше ресурсов, чем вы ему выделили. В новом переводе от команды Spring АйО разберем, какие существуют базовые настройки кучи, GC и CPU помогают синхронизировать JVM с лимитами контейнера и не переплачивать за простаивающие ресурсы.

Okay first shot #aarch64 on Snapdragon...

#arm #snapdragon #ubuntu #linux

moving to MacBook, so fixed Newelle flatpak to run on aarch64 too!

I fired up my Snapdragon X laptop over lunch to see if its been behaving, and do Windows updates. I haven't used it since November and it still had over 60% battery. Installing updates, and the silence is golden—no fan noise. I love how much less the fans on this machine turn on… shame about the spontaneous reboots and spotty Linux support though. On that, there's news that Fedora 44 will have out-of-the box support for these laptops, so I plan to give that a try.
