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.

Blaze: A High Performance C++ Math library
For typical game physics engines... not that much. Math libraries like Eigen or Blaze use lots of template metaprogramming techniques under the hood that can help when you're doing large batched matrix multiplications (since it can remove temporary allocations at compile-time and can also fuse operations efficiently, as well as applying various SIMD optimizations), but it doesn't really help when you need lots of small operations (with mat3 / mat4 / vec3 / quat / etc.). Typical game physics engines tend to use iterative algorithms for their solvers (Gauss-Seidel, PBD, etc...) instead of batched "matrix"-oriented ones, so you'll get less benefits out of Eigen / Blaze compared to what you typically see in deep learning / scientific computing workloads.
The codebases I've seen in many game physics engines seem to all roll their own math libraries for these stuff, or even just use SIMD (SSE / AVX) intrinsics directly. Examples: PhysX (https://github.com/NVIDIA-Omniverse/PhysX), Box2D (https://github.com/erincatto/box2d), Bullet (https://github.com/bulletphysics/bullet3)...

Does anyone know any good open source project to optimize?
I suspect most C++ physics libraries like Box2D (https://github.com/erincatto/box2d) or Bullet3 (https://github.com/bulletphysics/bullet3) could really benefit a lot from SIMD.
- After months of work, I'm excited to share the first release of Godot Jolt, an extension that integrates the Jolt physics engine into Godot, demonstrated using GDQuest's RoboBlast

X4's Upcoming Multiplayer Features Are a Huge Step Forward
No, they replaced Bullet with Jolt. That is considerably more than "some adjustment", regardless of what you think of the result.

Ive been programming for four years and I told my dad to watch long videos and complete your own projects to learn most efficiently. He thinks he’s ready to tackle any project after a ten minute video…
The first two have a bunch of great examples, and I’m tying them together by refactoring some of the THREE examples to fit the ECS paradigm defined in AFrame. then upping the ante by adding physics using AMMO, which is more challenging since it’s only a partial implementation of Bullet, and already poorly documented (yet popular) physics engine.

Their music is just too good
Plus, SM uses a system called bullet physics, I imagine this would be rather complex to rework into a modern engine such as Unreal or Unity (after all, the majority of performance issues come from the physics engine rather than the graphics engine)

Is anyone working on more effecient HDT-SMP?
The physics in HDT-SMP are actually being calculated outside of Skyrim's engine with Bullet, an open-source physics engine. So this isn't some limitation of Skyrim's engine.

Tetris Development 1 - Setting Up
Instead, I was recommended Godot by a fellow developer. It is an easy-to-pickup and beginner-friendly open-source engine, which I will use to develop the Tetris game.

Ask HN: Yo wants to build a game, I'm lost. What can I do?
Godot [1] is a very nice game engine. There's a game on Itch.io that teaches the scripting language it uses [2], and a ton of great tutorials on YouTube for beginners and experts alike.

Would love to see this for Godot (https://github.com/godotengine/godot). Maybe Maplibre too (https://github.com/maplibre/maplibre-native)!

My thought on different engines
Godot Engine is a free and open-source game engine. The story started as an in-house engine of an Argentinian studio in 2007, and since 2014, it's been a community-driven project with a lot of contributors.
