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.

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.

Alternatives to Makefile for Python
I like this pattern so much, I wrote an article about it; if you want to see what it looks like in real life, check this out.

reader 2.5 released – a Python feed reader library
It can also be used to build bookmarking / read later functionality similar to that of Tiny Tiny RSS; extracting content from arbitrary pages would be pretty helpful here.
To find out more, check out the GitHub repo and the docs, or give the tutorial a try.

sqlite-utils - my Python library and CLI tool for manipulating SQLite databases
Looking now through the Python API docs, I found the Quoting characters for use in search thing, which may come in handy for something I'm doing for my feed reader library (deduplicating articles). Not sure if I'll vendor it or add sqlite-utils as a new dependency, but it's good to know someone already solved this problem (I have a prototype, but I haven't really tested it).

Sunday Daily Thread: What's everyone working on this week?
I'm also working on the 2.0 version of my feed reader library. The backwards compatibility break allows me to clean up a bunch of unnecessary code and fix some bad design decisions; I've deleted 250 lines of code until now, and it's very satisfying.

PEP 661 -- Sentinel Values
The exact same problems None has when it's not a valid value. None is different from the variable type, that's why you have Optional[VarType], which is an alias for Union[VarType, None]; you can model this in exactly the same way: Union[VarType, MissingType]; here's an example.
