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.

When Optimising Code, Measure
I really like magic-trace [0].

Not that the exact tracing relies on Intel PT - support for AMD was added recently but uses perf so suffers from the same sampling/skew issues, but is still very useful.

Grafana Phlare, open source database for continuous profiling at scale
Would love to see this integrate with magic trace [1]. I'll need to look at the code for the flamegraph plugin, because handling nanosecond timestamps in flamegraphs seems to break most tools due to float precision.

How to break into Hudson River Trading?
As for inner workings, have you looked into magic trace? I want to play around with it but last I checked, it doesn't work on macs.

Brendan Intel.com
I really hope he can work with cloud vendors and Intel to make Processor Trace a more popular and easier to use capability.
It's unfortunate how https://github.com/janestreet/magic-trace and PMUs in general can't be used by lots of people using cloud VMs.

Quadrillion Rows Example
I'm the author of regular-table, one of the alternatives mentioned in the accompanying blog. We went through a similar set of requirements to OP (and did at one point use fin-hypergrid as well, and also the excellent phosphor-datagrid which is now lumino-datagrid), and came to a slightly different conclusion regarding rendering. We ultimately decided to revert to (albeit bespoke) virtual DOM rendering for many of the same reasons mentioned by other commenters, namely:
- Ask HN: Why are developers so stingy with “rows per page”?
