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.

OpenBSD KDE Plasma Desktop
Well of course they're not trying to replace macOS, for instance, but when an OS gets big enough to have offshoots and different front-ends and desktop environments and so forth, one would assume there are at least experimental attempts emphasizing ease of use, just like there are experiments to develop offshoots for any other purpose, from power users to pen testers. At least like, someone's toy project on GitHub or SourceForge. I just assumed BSD was big and well-established enough to have such efforts.
Besides GhostBSD, looks like there's also Lumina, and TrueOS/Project Trident?

Making cross-platform software using Linux that also runs on BSD
Oh, you might also look at the Lumina desktop which strives for minimal dependencies and portability across Linux+BSDs.

I'm bored with Gnome and KDE. Suggest me something that is drastically different than anything I've ever used before.
You might be interested in Lumina.

[7b7b] a fork of the lumina desktop
DBus was used only in this part of the code, also i wanted to follow what lumina is claiming about not using linux frameworks.

The Reality
There are at least two more independent Qt-based DEs: Lumina and Deepin. Also, MATE and Cinnamon are forks of GNOME.

So many GTK Desktop Environments, yet so little Qt ones
There are some more qt ones but no clue how actively they are developed: Lumina, cutefish, Trinity...

Hermit is a hermetic and reproducible sandbox for running programs
I think this tool must share a lot techniques and use cases with rr. I wonder how it compares in various aspects.
https://rr-project.org/
rr "sells" as a "reversible debugger", but it obviously needs the determinism for its record and replay to work, and AFAIK it employs similar techniques regarding system call interception and serializing on a single CPU. The reversible debugger aspect is built on periodic snapshotting on top of it and replaying from those snapshots, AFAIK. They package it in a gdb compatible interface.
Hermit also lists record/replay as a motivation, although it doesn't list reversible debugging in general.

Deep Bug
Interesting. Perhaps you can inspect the disassembly of the function in question when using Graal and HotSpot. It is likely related to that.
Another debugging technique we use for heisenbugs is to see if `rr` [1] can reproduce it. If it can then that's great as it allows you to go back in time to debug what may have caused the bug. But `rr` is often not great for concurrency bugs since it emulates a single-core machine. Though debugging a VM is generally a nightmare. What we desperately need is a debugger that can debug both the VM and the language running on top of it. Usually it's one or the other.
> In general I’d argue you haven’t fixed a bug unless you understand why it happened and why your fix worked, which makes this frustrating, since every indication is that the bug exists within proprietary code that is out of my reach.
Were you using Oracle GraalVM? GraalVM community edition is open source, so maybe it's worth checking if it is reproducible in that.

So you think you want to write a deterministic hypervisor?
https://rr-project.org/ had the same problem. They use the retired conditional branch counter instead of instruction counter, and then instruction steeping until at the correct address.

Is Something Bugging You?
That'll work great for your Distributed QSort Incorporated startup, where the only product is a sorting algorithm.
Formal software verification is very useful. But what can be usefully formalized is rather limited, and what can be formalized correctly in practice is even more limited. That means you need to restrict your scope to something sane and useful. As a result, in the real world running thousands of tests is practically useful. (Well, it depends on what those tests are; it's easy to write 1000s of tests that either test the same thing, or only test the things that will pass and not the things that would fail.) They are especially useful if running in a mode where the unexpected happens often, as it sounds like this system can do. (It's reminiscent of rr's chaos mode -- https://rr-project.org/ linking to https://robert.ocallahan.org/2016/02/introducing-rr-chaos-mo... )

When "letting it crash" is not enough
The approach of check-pointing computation such that it is resumable and restartable sounds similar to a time-traveling debugger, like rr or WinDbg:
