Alright, Fedi of the verse. Got a tech question for you that I seemingly cannot find an answer for, so I come to y'all nerds!

I'm currently trying to make an aarch64 VM on x86_64 hardware, which afaik, is entirely possible. I wanna emulate Windows on Arm, basically.

I'm using QEMU/KVM & Virt Manager, and I can get to the "posting" process, at which point it just... maxes out ONE core of my CPU, forever, until I close virt-manager. I've no idea why?

Any takers? #Tech #AskFedi #VirtualMachine

Oh and Virtualbox ain't working on Debian 13 (Trixi) you need to install it via Debian 12 (Bookworm) Now that gave me a fright as I use Virtual Machines for work.

and once installed I had to run this "sudo rmmod kvm_amd", as "VirtualBox can't enable the AMD-V extension" to get my virtual machine running

I'm starting a series of blog posts, in which I write a #bytecode #compiler and a #virtualMachine for arithmetic in #Haskell. We explore the following topics in the series:

- Parsing arithmetic expressions to ASTs.
- Compiling ASTs to bytecode.
- Interpreting ASTs.
- Efficiently executing bytecode in a VM.
- Disassembling bytecode and decompiling opcodes for debugging and testing.
- Unit testing and property-based testing for our compiler and VM.
- Benchmarking our code to see how the different passes perform.
- All the while keeping an eye on performance.

The first post of the series that focuses on writing the #parser is now out: https://abhinavsarkar.net/posts/arithmetic-bytecode-vm-parser/

#RUNBSD! But BoxyBSD now also starts to support #Linux! We're starting soon with the Linux support for already present users, offering free boxes:

* #AlmaLinux
* #Alpine
* #Debian
* #Devuan
* #CentOS
* #Fedora
* #Gentoo
* #OpenSuse
* #OpenEuler
* #RockyLinux

Just next to our core OS like #FreeBSD, #OpenBSD, #NetBSD, #MidnightBSD and #DragonflyBSD (and #illumos). This should also make the step easier to compare and test different scenarios where BSD provides a different behavior compared to Linux systems.

Thanks to @gyptazy for the implementation!

Mastodon (official) mobile apps and mastodon.social, mastodon.online web UI will include easily dismissable donation banner:
https://news.itsfoss.com/mastodon-in-app-donation-nudge/
(Some people often get mad if a project asks for donation within its software UI, but I think volunteer devs also deserve to get some payment for their work, it's fair to include a donation notice, if it doesn't annoy users with its placement.)

Bluesky introduces age verification (using payment cards, ID scans, or face scans) for accessing adult content and direct messaging, and content controls for UK users:
https://alternativeto.net/news/2025/7/bluesky-introduces-age-verification-and-content-controls-for-uk-users/
(Yeah we're heading into a dystopian future, where you can't use social media without giving up sensitive information... Or can't send messages because a small portion of predators also use that feature... It shouldn't be the responsibility of governments and social media platforms to protect children, it's the parents' task to protect their children. If governments would really care about protecting children, they would rather push campaigns targeted towards parents to raise awareness of the importance of paying attention what their child is doing online. But nah, this "protect children" thing is only pushed for emotional manipulation, so that the governments can cover their arse, while building surveillance infrastructure.)

A note on my #UltimaVM for #RISC_OS users: when coding on Ultima, we don't care at all about RO multistasking, we just code like on Windows, Linux or macOS. If we want to run an Ultima App in the desktop we just use the `--mt` option in the command line, everything else is handled by Ultima itself:👇
