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.

According to these https://github.com/lz4/lz4 values you need around ten (10) quite modern cores in parallel to accomplish around 8GB/s.

> The downside of lz4 is that it can’t be configured to run at higher & slower compression ratios.
lz4 has some level of configurability? https://github.com/lz4/lz4/blob/v1.9.4/lib/lz4frame.h#L194
There's also LZ4_HC.

Get your bootloader unlocked via Download mode and then obtain your stock firmware, preferably for your current region https://samfw.com (Download mode: CARRIER_CODE). Get the boot image from AP with 7zip, unpack from LZ4 with https://github.com/lz4/lz4/releases (drag and drop), patch with Magisk https://github.com/topjohnwu/magisk/releases/latest, grab the new image, name it "boot.img" and pack it into a .tar with 7zip and flash to AP with odin https://odindownload.com
An efficient image format for SDL
4 projects | reddit.com/r/gamedev | 28 Sep 2022
After some investigations and experiments, I found out that it was the PNG compression (well, decompression I should say) that took a while. So I've made some experiments using the LZ4 compression library, which is focused on decompression speed, and it turned out to be an excellent solution!
Bzip3 – a better and stronger spiritual successor to bzip2

If anyone just cares for speed instead of compression I’d recommend lz4 . I only recently started using it. Its speed is almost comparable to memcpy.
I just took a random screenshot and made it look prettier. [ I don't know if this counts as fanart ]

E: Realtime compression (A good compression library like Zstandard can make a game less than half the size while taking a tiny amount of CPU power when loading stuff. I think thats a pretty worthwhile trade.) (ZSTD github) (LZ4 github)

lz4 for maximum decompression speed, for data that is often read but rarely written
How to become a tools/graphics/engine programmer

Getting lost in material models is tempting. But, at this point you are overdue for working on your own asset pipeline. glTF is great. But, you should learn how to do it yourself. The hardest part will be reading source asset files. The FBX SDK is painful. Assimp isn't great either. Writing your own exporter to your own intermediate text format from Maya or Blender would be good if you are up for it. From whatever source, make your own archive format and binary formats for meshes, animations, textures and scenes. Use https://github.com/lz4/lz4 for compression. You should be able to decompress a list of assets into a big linear array and use them right there with just a bit of pointer fix-up. Minimize the amount of memory you have to touch from start to finish. Data that is going to the GPU (textures, vertex/index buffers) should decompress straight into mapped buffers for fast uploads.
LZ4, an Extremely Fast Compression Algorithm
9 projects | news.ycombinator.com | 27 Jan 2021
I'm not a fan of the stacked bar charts, I like the table of data for "Benchmarks" on the github source page: https://github.com/lz4/lz4
It makes it very clear where LZ4 fits into comparisons with compression speed, decompression speed and compression ratio
Introducing zune-inflate: The fastest Rust implementation of gzip/Zlib/DEFLATE
2 projects | reddit.com/r/rust | 11 Feb 2023
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
4 projects | news.ycombinator.com | 14 Oct 2022
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.

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.2 projects | news.ycombinator.com | 4 Aug 2022
Convenient CPU feature detection and dispatch in the Magnum Engine

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)
4 projects | news.ycombinator.com | 28 Mar 2022
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.
