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.

Git log is not a changelog
we use https://github.com/anchore/chronicle to generate release notes in a changelog format using the issues and PRs from GitHub as the source of truth. In this way time well spent in the curation of issues and PRs (which is something we need to do anyway) means that we automatically get release notes for free. (disclaimer: I'm the author of chronicle)

Keep a Changelog
The approach I like to take is to curate issues and PR with semantic titles and organize them by label ("bug", "enhancement", etc) or linking PRs to an already curated issue. This way automation can use these to generate the changlog for me on each release based on closed issues and unlinked PRs since the last release.
We wrote Chronicle to do that automation for us: https://github.com/anchore/chronicle .
The nice thing about this... since you typically curate issues during the development process anyway, if you're doing that right then you get a nice looking changlog for free! We use this approach with our core tools, Syft and Grype (some changlog examples: https://github.com/anchore/syft/releases/tag/v0.31.0 and https://github.com/anchore/grype/releases/tag/v0.26.1 ).
Always happy to hear new feature ideas and possible customizations for Chronicle (put in an issue and let's chat )!

Ask HN: What are some 'cool' but obscure data structures you know about?
Tries (or prefix trees).
We use them a lot at Pyroscope for compressing strings that have common prefixes. They are also used in databases (e.g indexes in Mongo) or file formats (e.g debug symbols in macOS/iOS Mach-O format are compressed using tries).
We have an article with some animations that go into details about tries in case anyone's interested [0].

Question: How do you handle oversized heap analysis?
You could use continuous profiling with Pyroscope which uses async-profiler under the hood, but with the added functionality that you can add relevant tags to your VMs (example).

JFR (Java Flight Recorder) Parser written in Go
Java Flight Recorder (JFR) is a format for collecting diagnostic and profiling data from Java applications. A while back someone created an issue for Pyroscope , an open source continuous profiler written in Go, to support ingesting profiles in JFR format, but there were no existing parsers that were also written in Go.

flamegraph.com - a new website for uploading, analyzing, and sharing pprof profiles
This cloud version is actually a slimmed-down version of Pyroscope which is open source and so you can run it locally.

We created flamegraph.com - A website for uploading, analyzing, and sharing flamegraphs
At Pyroscope (open source continuous profiling) we use flamegraphs extensively to visualize and analyze profiling data. However, one of the worst parts about using flamegraphs for analysis is that they are kind of annoying to share.
