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.

My favourite Git commit (2019)
> On my work I make 1-15 commits a day. If I have to spend thought cycles on the commit message, that is time that goes from other productive endeavours.
I make roughly that many commits a day as well. If something's easy to understand I'll put in a simple commit message (e.g. [1]), but I do put in the effort for more complicated ones.

Oxide Computer releases distribution of illumos intended to power the Oxide Rack
> I also wonder if internally Linux is used for development of the platform itself
Developers at Oxide work on whatever platform they'd like. I will say I am in the minority as a Windows user though, most are on some form of Unix.
> so they can create "virtual" racks to dogfood the product without full blown physical racks.
So one of the reasons why Rust is such an advantage for us is its strong cross-platform support: you can run a simulated version of the control plane on Mac, Linux, and Illumos, without a physical rack. The non-simulated version must run on Helios. [1]
That said we do have a rack in the office (literally named dogfood) that employees can use for various things if they wish.

OpenAI Used Kenyan Workers on Less Than $2 per Hour to Make ChatGPT Less Toxic
When we started the company, we knew it would be a three year build -- and indeed, our first product is in the final stages of development (i.e. EMC/safety certification). We have been very transparent about our progress along the way[0][1][2][3][4][5][6][7] -- and our software is essentially all open source, so you can follow along there as well.[8][9][10]
If you are asking "does anyone want a rack-scale computer?" the (short) answer is: yes, they do. The on-prem market has been woefully underserved -- and there are plenty of folks who are sick of Dell/HPE/VMware/Cisco, to say nothing of those who are public cloud borne and wondering if they should perhaps own some of their own compute rather than rent it all.

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/...

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.

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.

Use a BSD style license for your Open Source Project (2021)
> Since then, illumos has rewritten all those components
But apparently kept the same license?
>> Most of the existing code is licensed under the CDDL and we expect new code will generally be under this license as well.[0]
