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.

Anyone have luck getting viewcore to work? panic: weird mapping Read|Write|Exec
I've been trying to find a utility that would let me peek into the coredump and see whats going on. I ran into viewcore (https://github.com/golang/debug/tree/master/cmd/viewcore) which seems to be a rather nice utility... unfortunately it panics:

Hi everyone, How could you find the lines executed for a particular method call in any language (java, go..) using eBPF?
They were bought by Elastic, maybe they'll open source it. There's also https://github.com/parca-dev/parca

How do you monitor your Go apps?
an alternative option to pyroscope to do continuos profiling in production could be parca.dev check and here

Continuous Profiling in Kubernetes Using Pyroscope
Parca collects, stores and makes profiles available to be queried over time. It is open source and can be deployed on production environments as Parca focuses on sampling profiling two main types of profiles: tracing and sampling.

Launch HN: ContainIQ (YC S21) – Kubernetes Native Monitoring with eBPF
Polar signals develops Parca [0] which is another eBPF observability tool, and Isovalent develops Cilium [1] which is built on eBPF as well. Genuinely curious if there are differences, or if eBPF only allows for specific observability functionality and each tool has it all.
