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.

AprilTags
Now I know why. The blog post about the GM1 release says this: "The 2023-2024 CENTERSTAGE℠ field will contain AprilTag targets, developed by researchers at the University of Michigan to provide low overhead, high accuracy localization for applications such as robotics."

How can I count the number of stripes to identify an object?
There are solutions available to identify tags like this, only with more bits of data. One example is April tags: description, Github.

[help] looking for a simple way to scan a torso to build a mannequin
You can generate April tags (https://april.eecs.umich.edu/software/apriltag) and print them on letter address labels, and place those on your subject’s skin. Measure the distance between them. Then, in reality capture (www.capturingreality.com) you use “detect markers” to automatically identify those April tags, and “define distance” to input the precise distance between them. Click “update” in alignment to correct the scaling, and ta-da! - you’ve got a scaled model.

Retroreflective tape phasing out
I haven't seen anyone post about this yet, so I thought I'd share. From the blog, FIRST will be phasing out of retroreflective tape for vision tracking in the 2023 season. The field will have both retroreflective tape and Apriltags

Simple pattern detection and reconition
Just use this - good enough for NASA, compiles on basically anything, and small enough codebase to tinker.

Evaluate CPU requirement for C++ program
FYI: my program is pretty similar to this example: https://github.com/AprilRobotics/apriltag/blob/master/example/opencv_demo.cc

isaac-ros-common questions/issues
It looks like they just updated everything on the git hub and i am specifically trying to get the apriltags node running. NVIDIA-ISAAC-ROS/isaac_ros_apriltag: CUDA-accelerated Apriltag detection and pose estimation. (github.com)

Evaluate CPU requirement for C++ program
Yes that would be great, the only implementation I found is https://github.com/NVIDIA-ISAAC-ROS/isaac_ros_apriltag which I'm not sure how to implement. I'll still give it a try !
