Pretty interesting how an old hardware works well and compute well in the strange configurations.

Prereqs: Intel Atom N2800 1866 MHz and 2 Gb RAM.

Since there are no NetBSD builds of xray-core and v2raya — I spin up a FreeBSD VM inside the Qemu and without NVMM accelerator (not supported by my CPU). Execute these programs inside this VM — and the server still running and even doesn't overload drgn_shocked

Hello Anti-Ai, Anti-Tech, Anti-Fun Complainers,

Go ahead and keep being miserable while the rest of the world moves on without you; leveraging advanced technology to further the human race, engaging in complex scientific research with supercomputers, solving complex medical diagnoses, improving the success rate of invasive surgical procedures, and continuing efforts to create the world which you already benefit from — despite all of those misinformed views about this evolving technology you refuse to understand.

> "but.. the media told me that skynet.. and those evil chatbots.. something about hallucinations.. and our burning desire to anthropomorphize machine intelligence".

Anyway: https://zenodo.org/records/17196870 here's some recent fun with LLMs.

> [Kelsi Davis] decided to port the Macintosh System 7 OS to run on native x86 hardware, which would be challenging enough with full access to the source code. However, she instead performed this task by analyzing and reverse engineering the System 7 binaries with the aid of Ghidra and a large language model.
>
> Soon enough, she had the classic System 7 desktop running on QEMU with a fully-functional Finder and the GUI working as expected. [Kelsi] credits the LLM with helping her achieve this feat in just three days, versus what she would expect to be a multi-year effort if working unassisted.

Zenodo

Leveraging Artificial Intelligence for Automated Reverse Engineering of Legacy Software Systems

We present an AI-assisted reverse engineering framework that achieves dramatic speedups—on the order of hundreds of times faster than traditional manual methods—by orchestrating specialized agents for evidence curation, struct recovery, and code drafting. Using this approach, we recreated a bootable prototype of Apple System 7.1 from binary analysis in just 3 days, a task that would normally require months or years. The framework enforces strict provenance tracking, tying each change to either disassembly bytes or runtime verification under QEMU. Rather than reporting abstract accuracy percentages, we emphasize artifact-based validation: screenshots, serial logs, and resource extractions that demonstrate Chicago font rendering, menu bar behavior, desktop patterns, and icon display. This work shows how carefully scoped AI assistance, coupled with human review and a structured verification loop, can transform reverse engineering from a slow artisanal process into a systematic, reproducible workflow for preserving computing history and modernizing legacy systems.

I like the minimal TUI installer of OmniOS. The system was installed in less than 2 minutes without problems.

Now I can start exploring it...

Just finished updating my SlackBuild to build QEMU 10.1 cleanly on Slackware 🎉

✨ Highlights of QEMU 10.1 on x86_64:

- Improved CPUID handling (guests see cleaner CPU flags)

- KVM backend improvements (TDX/SEV-SNP support for servers on newer kernels)

- TCG accuracy improvements

Still runs great on laptops for daily Slackware VM use

I’ve updated my SlackBuild so it compiles QEMU 10.1 without Meson option issues.
Grab it here:

Back to working on my #homelab after a break. It isn't very apparent or easy to find the cloud images for #ubuntu or #debian to run #VM. I have this setup via #libvirt #qemu & #cockpit. Took some time to find the correct permissions on #ArchLinux but quite a breeze to use afterwards.
