Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I just discovered Illumos based distributions, what are the main differences between those and FreeBSD ?
key features at OmniOS Community Edition

Looking for more ideas
OS Challenge: Try out an Illumos (OpenSolaris) image in a VM (there are Solaris kernel options available in Proxmox). If you want something fun, install OmniOS and create a Linux zone on it. So cool to run Linux on Solaris. https://omnios.org/

Virtual machine efficiency
While UTM is much better at resource usage, it's not perfect. Virtualbox seems to emulate more of a system instead of passing it through to the hypervisor and so is better for running more unusual OSes. I have two VMs there running Illumos which I have yet to figure out how to boot in UTM. A problem that I think is related to UTM's greater use of the hypervisor is that you can't suspend and resume VMs that use it instead of being emulated, so I've still got a few VMs hanging around in Virtualbox which spend most of their time suspended. Finally, what stops me from using UTM at work is that you can't use it as a Vagrant provider. This is incredibly annoying, as the lack of a decent virtualization application makes the otherwise very nice M1 Macs nothing more than pretty toys. I expect that this glaring lack will be fixed within the next couple of years.

Just getting started
Can anyone recommend a good place to start learning OmniOS? Coming from Debain world. Other than the documentation on omnios.org, I only found a few blog posts here and there...

I was thinking about more "exotic" OS's
OpenIndiana is pretty neat. It has quite a few cool features like Zones, DTrace and Crossbow. ZFS is another big feature but you have already said that you don't really care about that. Hardware support is kinda lacking, but improving. Also it's rolling release so if you're like me and don't like that, OmniOS might be a better option; it's another illumos based OS.

QEMU Version 9.0.0 Released
My most-wanted QEMU feature: https://github.com/qemu/qemu/commit/a2260983c6553
Using `gic-version=3` on macOS you can now use more than 8 cores on ARM chips.

Autoconf makes me think we stopped evolving too soon
A better solution is just to write a plain ass shell script that tests if various C snippets compile.
https://github.com/oilshell/oil/blob/master/configure
https://github.com/oilshell/oil/blob/master/build/detect-pwe...
Not an unholy mix of m4, shell, and C, all in the same file.

These are the same style as a the configure scripts that Fabrice Bellard wrote for tcc and QEMU.
They are plain ass shell scripts, because he actually understands the code he writes.
https://github.com/qemu/qemu/blob/master/configure
https://github.com/TinyCC/tinycc/blob/mob/configure
OCaml’s configure script is also “normal”.
You don’t have to copy and paste thousands of lines of GNU stuff that you don’t understand.

Revng translates (i386, x86-64, MIPS, ARM, AArch64, s390x) binaries to LLVM IR
> architectural registers are always updated
In tiny code, the guest registers (global TCG variables) are stored in the host's registers until you either call an helper which can access the CPU state or you return (`git grep la_global_sync`). This is the reason why QEMU is not so terribly slow.
But after a check, this also happens when you access the guest memory address space! https://github.com/qemu/qemu/blob/master/include/tcg/tcg-opc... (TCG_OPF_SIDE_EFFECTS is what matters)
But still, in the end, it's the same problem. What QEMU does, can be done in LLVM too. You could probably be more efficient in LLVM by using the exception handling mechanism (invoke and friends) to only serialize back to memory when there's an actual exception, at the cost of higher register pressure. More or less what we do here: https://rev.ng/downloads/bar-2019-paper.pdf

Multipass: Ubuntu Virtual Machines Made Easy
Some of these tools include Oracle VM VirtualBox (that I've used since before the acquisition of Sun Microsystems by Oracle), VMWare Workstation Player, and QEMU, but last year, I found out about Multipass.

Libsodium: A modern, portable, easy to use crypto library
For C/C++ projects that use meson as the build system, there is an excellent way to manage dependencies:
https://mesonbuild.com/Wrapdb-projects.html
https://mesonbuild.com/Wrap-dependency-system-manual.html
meson will download and build the libraries automatically and give you a variable which you pass as a regular dependency into the built target:
https://github.com/qemu/qemu/tree/005ad32358f12fe9313a4a0191...
https://github.com/harfbuzz/harfbuzz/tree/main/subprojects
https://github.com/harfbuzz/harfbuzz/blob/37457412b3212463c5...
Or, if you're using proper operating systems, they're managed by the usual package manager, just like everything else.

Top 6 Virtual Machine Software in 2023
For all the users of the Linux platform, QEMU is the VM that you should go for. This software comes without any price tag and works as an emulator of various machines with utmost ease and completion; the software uses dynamic translations to emulate hardware peripherals and enhances its overall performance. If you are using QEMU as a virtualizer, then it will function exactly like the host system (provided you have the right set of hardware).

UTM for Developers
In this tutorial, we set up macOS and Windows virtual machines on UTM, a macOS application that provides a GUI wrapper for QEMU, a powerful open-source emulator and virtualizer. UTM allows you to easily manage and run virtual machines without memorizing complex commands. It also has special handling for macOS, making it simpler to install compared to other virtual machine software.
What are some alternatives?
