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.

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.

gonna go off-topic, but doesn't LZ4 exists? I know IOI Interactive uses it for HITMAN 3.

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)

That's great news. I implemented LZ4 for the Apple II, but Yann Collet is the creator of the algorithm.

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

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

It's hard to tell, how much since the latest lz4 1.9 has been improved, because the (benchmarks)[https://github.com/lz4/lz4/commit/31763c59fca9a38bc697cd37f591d6ba385f7614#diff-b335630551682c19a781afebcf4d07bf978fb1f8ac04c6bf87428ed5106870f5] are executed with different processors3 projects | reddit.com/r/rust | 18 Jan 2021
Which version are you using ? Is that the reference implementation at github.com/lz4/lz4 ?

Re: Zlib memory corruption on deflate (i.e. compress)
4 projects | news.ycombinator.com | 28 Mar 2022
This seems to be a minor bug, in that it is only triggered using unusual (and rather unlikely) deflate parameters.
But, looking into this bug, I was sort-of interested to see how it was handled. The change log for 1.2.12 (2022-03-27) indicates the issue was resolved ("Fix a bug that can crash deflate on some input when using Z_FIXED"). Yet, in what seems to be the canonical Zlib repository (https://github.com/madler/zlib), I was unable to find a corresponding commit.
None of commits this year (7, so not too hard to review) seem to be particularity meaningful changes, and in particular yesterday's 'zlib 1.2.12' commit seems to only consist of version/copyright updates.
So, does anyone have any idea where to find the commits related to the change log entry? (Note that I'm not disputing the issue is actually fixed, I'm just trying to improve my Github reading skills...)4 projects | news.ycombinator.com | 28 Mar 2022
