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.

The Near-Lossless Image Formats Using Ultra-Fast LZ Codecs
It's important to notice that ZPNG beats virtually all QOI variants, as discovered in: https://github.com/nigeltao/qoir

Hello, PNG
But most platforms these days have some form of CRC32 "acceleration". Adler32 is easy to compute so I'm even less concerned there.
I spent a bunch of time optimising the code in [fpnge](https://github.com/veluca93/fpnge), which is [often notably faster than fpng](https://github.com/nigeltao/qoir/blob/5671f584dcf84ddb71e28d...), yet checksum time is basically negligible.
Having said that, the double-checksum aspect of PNG does feel unnecessary.

Quite OK Image is now my favorite asset format
* AFAIK it does this while beating the original QOI in terms of speed AND efficiency
Lots of benchmarks in: https://github.com/nigeltao/qoir
QOIX
QOIX is my very own version that adds:

CVE-2023-4863: Heap buffer overflow in WebP (Chrome)
So the real issue here is that the lack of tree validation before the tree construction, I believe. I'm surprised that this check was not yet implemented (I actually checked libwebp to make sure that I was missing one). Given this blind spot, an automated test based on the domain knowledge is likely useless to catch this bug.

Notes: Advanced Node.js Concepts by Stephen Grider
In the source code of the Node.js opensource project, lib folder contains JavaScript code, mostly wrappers over C++ and function definitions. On the contrary, src folder contains C++ implementations of the functions, which pulls dependencies from the V8 project, the libuv project, the zlib project, the llhttp project, and many more - which are all placed at the deps folder.

Dear Pirates Donate as much as you can
Seeing the text in red got me thinking for a moment, "wow, didn't realize pirates had such love for an open-source compression library"
