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.

Legged Robots in Ignition / Gazebo
If you are not constrained to using Gazebo as the simulation environment, I would also suggest pybullet. (Here)[https://github.com/bulletphysics/bullet3/blob/master/examples/pybullet/examples/quadruped.py] is the quadruped simulation script, it is super simple to get it running and also meets your requirements(as mentioned in the question)

Microsoft wins FTC fight to buy Activision Blizzard
Halo was mostly all about single player and early multiplayer/local multiplayer but their online netcode has sucked since Blood Gulch. Lots of games do networking horribly, I have been in gamedev making networking and I hate most of what people do. The ones that have a clean natting, based on enet style reliable UDP channels, RakNet style punch are better (RakNet was good until Facebook bought it). It has come a long way but also fallen back. Valve source netcode (on github) is probably the best and you can check it out here. They started with the best in Quake networking, then to Source.

Multiplayer Networking Solutions
Raknet No longer worked on but from what I've read, it's complete and working. It has been used in many games between 2000 - 2010

Making a multiplayer server
Inconsistencies can be prevented by ensuring the server handles all operations and does so in a given order, then transmits the results to clients. I wrote a little about this for my game Avoyd a long while ago. Clients (including a client running the server) send an edit request via reliable ordered UDP (e.g. using Enet, Raknet, Steam Networking etc.) and the server places these in a single queue then performs the edits and sends the results back also using reliable ordered UDP.
