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.

Dwarf-Based Stack Walking Using eBPF
Thanks!
As @brancz mentioned, Delve uses DWARF unwind information to produce backtraces (they are stored in the .debug_frame section for Go).
You are right, Go enabled frame pointers for all architectures as of 1.17 [0]. This is enabled to allow profilers to work well, without having to use to techniques such as the one we describe in our post.
When it gets funny is that there's `gopclntab`, a 3rd option in Go to unwind stacks, used by `panic` and I believe other parts of the runtime. If you are interested in more details, Felix Geisendörfer's repo contains way more details [1]
