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.

Source code for Quake 2 rerelease
> Glad to see the source code released!
In case you were unaware, this is actually the source code of the rerelease of Quake II. The source code for the original Quake II has been released for many years[0], along with many of the id Software classics[1].

- Someone dropped the source code for Far Cry 1 on archive.org
- I fully support this.
-
What are some source codes to have read, and why?
I really enjoyed reading the Quake and Quake 2 source code, personally https://github.com/id-Software/Quake-2
- Ask HN: What piece of code/codebase blew your mind when you saw it?
-
What would you have gotten once you licensed the Quake engine in the late 90s?
Does ID provide you the full source code (as it is now on Github)?
- What was the "old," way of doing 3D graphics before shaders? (fixed function pipelines and such)
- are there tutorials for code organization for games in C?
- Interesting Halo 3 script comments.
-
If you license your code as GPL, and Assets as CC-BY-NC-SA, what license do you then use for the compiled binary?
There's nothing stopping your from putting your code under GPL and your assets under copyright (no permissive license) or public domain. Code and assets don't need to be under the same license. See how id did it:

Mistral CEO confirms 'leak' of new open source AI model nearing GPT4 performance
I often like to think about https://github.com/chrislgarry/Apollo-11 as an analogy. It's public domain with available source, in the assembly language in which it was written... so it fills all the definitions of OSS!
But the process by which that code arose, the ability to modify any line and understand its impact (heh) on a real execution environment, is dependent on a massive process that required billions of dollars and thousands of the smartest people on the planet. For all intents and purposes, without that environment, it is as reliably modifiable as an executable binary in any other context - or a set of weights, in this one!

TIL an Oxford University physicist claimed that for the moon landing conspiracy to be true, around 411,000 people would’ve needed to keep it secret. He also suggests the hoax would’ve broken down in 3.68 years.
You can look at the Colossus 2A code written by Margaret Hamilton and her very small team on Github.

Software Disenchantment
My more positive take on this: our runtime environments are bloated because we have ways to enable trust, stability, and iteration speeds that people wouldn't have dreamed of in years past.
Your Notion desktop app and Google Chrome both support embedding & displaying multimedia content that's controlled by people that you may not trust, but they can draw on decades of engineering to sandbox that content. They can independently be updated without worrying about a centralized `flexbox.dll` that may or may not be the right version. They do not require building a new executable to make the vast majority of UI changes. And the cost is simply storage space and initial download bandwidth.
We can look with rose-colored glasses at an era of "every byte of assembly has been hand-crafted." I, too, look in awe at what was achieved with such things as https://github.com/chrislgarry/Apollo-11/tree/master/Luminar... . But that software, per https://en.wikipedia.org/wiki/Apollo_Guidance_Computer#Softw..., took 1400 person-years of work.
We have to compare apples to apples - the abstractions we have today would not prevent such a piece of software from being built, and indeed would allow us to build that exact software, even bit-for-bit the same, much more easily due to abstractions on our tooling itself. We have not departed a world where, given a nation-state budget, one could pay for 1400 person-years of work and create the AGC (though one might make arguments about the distraction levels of modern society, but that's a different thing entirely).
But we also exist in a world where I can build and ship a cross-platform video chat application in an afternoon (well, not counting app store approvals) and be reasonably confident that my app will be compatible with, and secure on, practically any computer or mobile device sold in the past half decade, regardless of how many other apps may have been installed on each device. I'd venture to say that Apollo engineers would, and do, find this aspect of our world fascinating, too.
