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.

Inverted pendulum realtime metrics
I think that's probably the way to go. There are a couple of launch files like that, I guess that use tracetools_launch (see here in one of the pendulum_bringup launch files) to actually record some timing statistics.

Inverted pendulum realtime metrics
Hello, I am doing my thesis in ros2, on linux with realtime preemt kernel and all the reccomended settings. The problem is, in older demo : https://github.com/ros2/demos/tree/rolling/pendulum_control Performance statistics got printed automatically, in a newer version :

Are lifecycle / managed nodes common and/or recommended?
Managed or lifecycle nodes make sense to me (see also design page). I've frequently used state machines for this sort of thing in the past, and it sounds like a good idea to have some infrastructure in place to avoid reproduction of effort.
What are some alternatives?
