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 
Processes graph from Munin. It shows that there are near 53 processes before 11:00 and near 65 processes after this time.
The memory usage by category graph. It shows rise of anon memory from 0.3 Gb to 0.8 Gb at near 11:00 or 12:00.
Load average graph from Munin. Overall usage were at near 0.3 but raised to 0.8 at 11:30. With one visible spike to 2.8 at near 12:50
CPU usage graph from Munin. The graph shows 5-10% CPU usage. The graph rises to near 5% at near 11:40. With one visible spike to 120% at near 12:50.

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.

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:
