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.

OpenIndiana Illumos Distro
Actually several docs in their repositories point to https://github.com/oxidecomputer/helios which... doesn't exist?
It does seem derived (rather than based) from OmniOS indeed, so little to do with OpenIndiana (https://news.ycombinator.com/item?id=33337086)

What Is PID 0?
We can see it is called sched. Why sched? This article talked about the historic role of PID 0 in process swapping. Process swapping is a scheduling problem (like a lot of problems in software). This is why swappers are traditionally called medium-term or memory schedulers. Illumos generally gives most groupings of kernel worker threads their own processes with their own PIDs, but one, called "sched", remains in PID 0, and its responsibility? Process swapping:

The Wikipedia article has now been hastily edited, and replaces a claim that was true only of certain Unixes other than Linux with a claim true only of certain Unixes including Linux. Is this an improvement?

eBPF Documentary
It may become a footnote on Linux, but Linux isn't the only system out there -- and DTrace remains alive and well in many systems (not least in its reference implementation in illumos[0]).

Oxide Computer releases distribution of illumos intended to power the Oxide Rack
Nobody's paid to have it pass Open Group Unix Branding certification tests
https://www.opengroup.org/openbrand/register/
so it can't use the UNIX™ trade mark.
But it's got the AT&T Unix kernel & userland sources contained in it.

In OpenZFS and Btrfs, everyone was just guessing
> it seems like this bug might actually date back to the very beginning of ZFS with Sun
Looks like you might be right about that. The oldest commit referenced in the fix [0] was from 2006[1], which was just months after Sun released ZFS.

Grokking AVL and RAVL Trees
It could be good for in memory stores / log-structured merged trees / other data store applications although it isn't used much now-days. I find them simpler to implement and understand than red-black trees -- although that's a matter of taste I suppose. They beat red-black trees in read-heavy loads (i.e. writes / updates are more costly for AVL trees than for Red-Black trees although they beat R-B trees for read-heavy loads). You can find another implementation in Illumos (an open source Unix operating system) available here: https://github.com/illumos/illumos-gate/blob/master/usr/src/...

OpenIndiana
It's high time that the Illumos developers patched https://github.com/illumos/illumos-gate/blob/master/usr/src/... and https://github.com/illumos/illumos-gate/blob/master/usr/src/... to just set the error flag and return, and made the #ifndef TIOCSTI path in https://github.com/illumos/illumos-gate/blob/master/usr/src/... the only path.
Because by the looks of https://github.com/illumos/illumos-gate/blob/7c478bd95313f5f... the C shell was fixed years ago.

Can SGI’s Enthusiast Community Bring IRIX Back to Life?
People are still actively working on Illumos. The last change was yesterday morning.
* https://illumos.org
People are still actively working on MirBSD. There's a CVS commit account that can be followed on the FediVerse.
* http://www.mirbsd.org
It's DragonFly BSD, not Dragon BSD, and the irony of that is that you missed FreeBSD, which is of course still going.
* https://dragonflybsd.org
* https://freebsd.org
As is GhostBSD, which tracks FreeBSD.
* https://ghostbsd.org
HardenedBSD is still going. Shawn Webb regularly talks about it on the FediVerse.

Linux distributions' relative popularity over time (by Distrowatch hits)
Its successor is still out there: Illumos. Though it seems to be mainly focused on backwards compatibility for existing custom applications as it still enforces things like an 8 character username limit.
