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.

What libraries do you miss from other languages?
It really depends on what part of Numpy you're using. You can easily leave Numpy's text parsing in the dust. And if you're doing element-wise operations on arrays, you can easily see 2-3x improvement with just numba.

Experience with heap bloat
Amdahl's Law will catch up with you really fast as you add threads with this strategy, but it's simple and is amenable to formats where you may have a delimiter in the middle of a record. For situations where you need maximum scaling and don't have the possibility of delimiters scattered into records, you can use the strategy I used to implement a faster numpy.loadtxt: https://github.com/saethlin/loadtxt/blob/master/src/inner.rs#L84 The general idea is that you divide the file among thread boundaries by splitting it on byte boundaries, then seeking from that byte offset to the end of the next record. This gets you non-interleaved sections so there's no duplicate parsing.

Looking for projects to contribute to
Tangentially, I just listened to an old cppcast about https://www.copperspice.com/, a QT fork with ambitions of being more c++-ey.

Worries about QT
There was already a fork of Qt 4. It is tootling along fine: https://www.copperspice.com/

Missing features in modern C++
BTW, CopperSpice sounds pretty close to what you're mentioning: https://www.copperspice.com

Using sigslot as replacement of Qt signals/slots
If you already have a lot of use of Qt your might find CopperSpice to be a reasonable compromisehttps://www.copperspice.com/

15 year .NET vet moving to Linux and C++ and Qt
exactly I'm quite happy to have my code written for me. If you don't like the moc you can use CopperSpice https://www.copperspice.com/

GUI for software, not games, but lighter than Qt ?

New 3.1.6 release of wxWidgets, free and open source library for creating portable native GUI applications, adding transparent support for high DPI artwork and much more, is now available.
CopperSpice might be worth looking at too. Coming from Qt you're probably going to like it better than wxWidgets.

Qt Creator 6 released
So I strongly dislike Qt. It's got a predatory vision for open source enforcement where they mislead their customers with spoopy language and make it harder and harder to download. In addition, they continue to insist on an architecture that's not even actually C++ (it's got a different grammar) despite it being completely possible to architect a better version of their designs in standard C++.

making a qt fork
See copperspice project. Originally forked to work around short coming of Meta-Object Compilation.
