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.

Show HN: Pzip- blazing fast concurrent zip archiver and extractor
Please note that allowing for 2% bigger resulting file could mean huge speedup in these circumstances even with the same compression routines, seeing these benchmarks of zlib and zlib-ng for different compression levels:
https://github.com/zlib-ng/zlib-ng/discussions/871
IMO the fair comparison of the real speed improvement brought by a new program is only between the almost identical resulting compressed sizes.

Introducing zune-inflate: The fastest Rust implementation of gzip/Zlib/DEFLATE
It is much faster than miniz_oxide and all other safe-Rust implementations, and consistently beats even Zlib. The performance is roughly on par with zlib-ng - sometimes faster, sometimes slower. It is not (yet) as fast as the original libdeflate in C.

Zlib Critical Vulnerability
Zlib-ng doesn't contain the same code, but it appears that their equivalent inflate() when used with their inflateGetHeader() implementation was affected by a similar problem: https://github.com/zlib-ng/zlib-ng/pull/1328
Also similarly, most client code will be unaffected because `state->head` will be NULL, because they (most client code) won't have used inflateGetHeader() at all.

Git’s database internals II: commit history queries
I wonder if zlib-ng would make a difference, since it has a lot of optimizations for modern hardware.

Computing Adler32 Checksums at 41 GB/s
zlib-ng also has adler32 implementations optimized for various architectures: https://github.com/zlib-ng/zlib-ng
Might be interesting to benchmark their implementation too to see how it compares.

games-emulation/dolphin-9999 is failing to build because devs switched to minizip-ng and zlib uses minizip. I'm not sure how to get it to build now, details in post.
(2) There are many packages that rely upon zlib and minizip and switching those underlying dependencies is easier said than done. We can't drop zlib completely and switch: "The idea of zlib-ng is not to replace zlib, but to co-exist as a drop-in replacement with a lower threshold for code change." - https://github.com/zlib-ng/zlib-ng

Re: Zlib memory corruption on deflate (i.e. compress)
There are already active zlib forks (e.g. https://github.com/zlib-ng/zlib-ng), the problem is with having people move to them. It takes a lot of effort to move mindshare from the original version to a fork, there's some historical examples of it happening, but not a ton.

Lottie under the hood
Actually, that's not entirely accurate. The lottie-web library itself doesn't support rendering to WebGL. However, there is a package called canvaskit-wasm that wraps Skia (a graphics engine) with WebAssembly (wasm). This package includes a module called skottie which supports rendering animations into a WebGL surface. However, there is a drawback with this approach: using wasm requires loading a relatively large package, and it's uncertain whether all features are supported correctly, as the official compatibility table that tracks lottie support on different platforms does not include skottie.

Due to popular demand, here’s part 2
The imgs are mainly used by Tencent QQ and Baidu Tieba users. QQ and Tieba compress imgs by default, so the popular imgs (in China we call them "屌图" or "表情包") would be compressed million of times during the spreading, causing the super low quality. These APPs on Android are using Skia for image processing, which suffering from a legendary bug: result would be more green. The bug was fixed in 2016: https://github.com/google/skia/commit/c7d01d3e1d3621907c27b283fb7f8b6e177c629d

Graphic Library for C
There’s also Skia by Google. Used by Android and Google Chrome.
What are some alternatives?
zstd - Zstandard - Fast real-time compression algorithm
bgfx - Cross-platform, graphics API agnostic, "Bring Your Own Engine/Framework" style rendering library.
ZLib - A massively spiffy yet delicately unobtrusive compression library.
nanovg - Antialiased 2D vector drawing library on top of OpenGL for UI and visualizations.
Minizip-ng - Fork of the popular zip manipulation library found in the zlib distribution.
GLFW - A multi-platform library for OpenGL, OpenGL ES, Vulkan, window and input
libdeflate - Heavily optimized library for DEFLATE/zlib/gzip compression and decompression
Atomic Game Engine - The Atomic Game Engine is a multi-platform 2D and 3D engine with a consistent API in C++, C#, JavaScript, and TypeScript
brotli - Brotli compression format
Ogre 3D - scene-oriented, flexible 3D engine (C++, Python, C#, Java)
uzlib - Radically unbloated DEFLATE/zlib/gzip compression/decompression library. Can decompress any gzip/zlib data, and offers simplified compressor which produces gzip-compatible output, while requiring much less resources (and providing less compression ratio of course).
