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.

Shot this using the Sony A7Cii handheld
I am no videographer and only read somewhere about gyro-stabilization and https://gyroflow.xyz So maybe that's an alternative to that software. Just leaving it here.

I like rust but want to use Qt.
You can get pretty far with Rust + Qt and I've been very happy with it, see Gyroflow

Any good beginner open source projects for a guy with a math background?
I need some math in Gyroflow for lens geometry and lens projection if you have experience with that

Qt Creator 12 Released
Rust has quite decent support for QML though. One of the really famous video footage stabilizer apps uses Rust with QML: https://docs.gyroflow.xyz/app/technical-details/used-technol..., and that is a non trivial UI: https://gyroflow.xyz/

Hero 10 Black overheats in Time Warp - options?
I think you would get the same result if you just recorded a regular video (at whatever resolution you want and a minimal framerate), then pass it through something like Gyroflow and increase the speed. Downside — it’s not automatic and you can’t preview on the camera. Upside — it won’t overheat you have more options to tweak after the fact.

A gimbal for travel or go handheld?
My buddy and I have been playing with Gyroflow (free and open source) for stabilization. It uses the A7C's gyro data to smooth out handheld footage. There are a ton of options to play with, too - much more to work with than Resolve, which is what we had been using. We've had solid results on the A7C and excellent results with the BMPCC6K.

Stabilization Algorithm
Maybe it wouldn't be a bad idea to dig into the Gyroflow's sources.

Tilt angle data
You can convert that data into a CSV using Gyroflow in combination with this Python script.

3rd Edition of Programming: Principles and Practice Using C++ by Stroustrup
This is overly dramatic. The "keywords" are just macros. If you don't want an additional preprocessor to generate code in a separate .cpp file from these macros, you can use https://github.com/woboq/verdigris
The concurrency model, object ownership and life cycle you are mentioning are not part of C++, those are just conventions in specific C++ user groups - Qt code compiles plain and simple with pretty much every conformant C++ compiler and that makes it as much C++ as anything else.

Qt Creator 12 Released
There were a couple of attempts in that direction, but i haven't really seen them used in any production codebase.

Will C++ ever get a standard GUI/2D Graphics library?
Is Moc for signals and slots still needed? Mind you, I haven't used Qt in 15 years, but I was sure I heard about some standard C++ way of building Qt apps without needing the MOC prebuild step (IIRC https://woboq.com/blog/verdigris-qt-without-moc.html).

KDE Plasma development switches to Qt 6 tomorrow
Nope, Qt 6 still uses moc. I don't think modern C++ meta programming is quite capable of entirely replacing moc. The closest thing I'm aware of is [0], but it requires additional macros compared to what moc requires, and compilation speed can suffer. Chances are moc won't be dropped until full reflection lands, if ever, and even then if compilation speed is too bad I wouldn't be entirely surprised if moc remains.

Carbon Language: An experimental successor to C++
> it's possible to do Qt without moc even in C++ with https://github.com/woboq/verdigris/, why wouldn't it be possible from D ?
You're talking about an entirely different thing. While OP was referring to the current state of D's ecosystem and the impact that missing key frameworks have on hindering adoption, you're arguing about the theoretical possibility of writing a framework with a language, which really does not address OP's point.

GUI for software, not games, but lighter than Qt ?
And much more importantly, MOC specifically is a code generator which has a competitor without the code generation requirement. Fully compatible even. So no, sorry "Qt is bad because MOC" stopped being an argument years ago (if it ever was).
