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.

Why I enjoy using the Nim programming language at Reddit.
Another example of Nim being really fast is the supersnappy library. This library benchmarks faster than Google’s C or C++ Snappy implementation.

Stretch iPhone to Its Limit: 2GiB Stable Diffusion Model Runs Locally on Device
It doesn't destroy performance for the simple reason that nowadays memory access has higher latency than pure compute. If you need to use compute to produce some data to be stored in memory, your overall throughput could very well be faster than without compression.
There have been a large amount of innovation on fast compression in recent years. Traditional compression tools like gzip or xz are geared towards higher compression ratio, but memory compression tends to favor speed. Check out those algorithms:
* lz4: https://lz4.github.io/lz4/
* Google's snappy: https://github.com/google/snappy
* Facebook's zstd in fast mode: http://facebook.github.io/zstd/#benchmarks

Compression with best ratio and fast decompression
Google released Snappy, which is extremely fast and robust (both at compression and decompression), but it's definitely not nearly as good (in terms of compression ratio). Google mostly uses it for real-time compression, for example of network messages - not for long-term storage.

How to store item info?
Just compress it! Of course if you will you ZIP, players will able to just open this zip file and change whatever they want. But you can use less popular compression algorithms which are not supported by default Windows File Explorer. Snappy for example.

Apple Ramps Up R&D Intensity to Pre-iPhone Levels

HFS Origins: The Turbo File System (2017)
I think NeXT might've written an HFS Standard reader or something, but they used the Apple code for HFS+ so it ended up as a hybrid.

Windows 11 Insider Preview — Rust in the Windows Kernel
Mach message passing and objc message passing have no relation. I don’t think xnu contains much if any objc.

Apple M1/M2 systems can now run Windows games like as Cyberpunk 2077, Diablo 4 and Hogwarts Legacy thanks to its new emulation software - VideoCardz.com
Obviously not all of its, but they contribute quite a bit. https://opensource.apple.com/releases/

Apple releases a Game Porting Tool, based on open-source platform Wine, which can translate DirectX 12 into Metal 3, a potentially massive step for Mac gaming
here is the kernel source (they have branches for each individual macos release with its darwin kernel ver, macos 13 is ver 8792.xx.x for instance): https://github.com/apple-oss-distributions/xnu

Apple’s new Proton-like tool can run Windows games on a Mac
Apple does plenty of open source stuff. Safari's browser engine, Swift, libdispatch, the XNU kernel used by iOS and macOS, etc. And macOS is generally packed with open source things, like the default shell, zsh. Also, Metal actually predates Vulkan, so Vulkan was definitely not established when they started focusing on Metal. Yeah, they probably should consider supporting Vulkan now, but it's nothing to do with open source. The main beneficiaries of Apple supporting Vulkan would be people porting closed-source games.

- Believe it or don't, Idc, but I am the dude who "forced" Apple to open-source everything. Hackintosh ftw :D
