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.

CVE-2023-2163: How we found and fixed an eBPF Linux Kernel Vulnerability
DTrace and eBPF are "not so different" in the sense that dtrace programs / hooks are also a form of low-level code / instruction set that the kernel (dtrace driver) validates at load. It's an "internal" artifact of dtrace though, https://github.com/illumos/illumos-gate/blob/master/usr/src/... and to my knowledge, nothing like a clang/gcc "dtrace target" exists to translate more-or-less arbitrary higher-level language "to low-level dtrace".
The additional flexibility eBPF gets from this is amazing really. While dtrace is a more-targeted (and for its intended usecases, in some situations still superior to eBPF) but also less-general tool.

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.

Reentry – An Orbital Simulator
Maybe not surprising at all. The author open-sourced Orbiter in 2021 [1]. It's MIT [2], so anyone can pick up from where he left off and create a commercial version:

- Would anyone like to build an Open Source KSP-like thing?

Open-source wind or solar power simulation
Also if you want to work on wind based simulation maybe this project might interest you https://github.com/orbitersim/orbiter The flight dynamic model is not super accurate and the author is not using the off the shelf library like jsbsim so a lot of improvements are possible.

Think you guys might appreciate this :)
Still the same, but now it's gone open source, hoping for a quicker development by the community now :)

PSA: Orbiter vs "OpenOrbiter"
"OpenOrbiter" is a misnomer, because Orbiter is already open and under MIT. I want everyone to know and understand that the real Orbiter repo, with commits being directly made by the good doctor is this one: https://github.com/orbitersim/orbiter

Games I can contribute too.
If you like space there is vega strike , pioneer and orbiter.
- Is there an explanation of the Orbiter codebase, like what part is the "main" where it all starts kind of thing?
- Orbiter launcher seems to have low text quality?

As a sidenote, it looks like the author released orbiter on GitHub: https://github.com/orbitersim/orbiter
