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.

Pharo 11
IMO it's a good tool for web scraping. The reason: you can do web scraping with Parasol (i.e. Selenium [1]) and then if you need visualization tools then you can immediately use Roassal [2]. The thing is: Pharo and the fact that it's more GUI-oriented than other programming languages, allows for data visualization a bit easier.
Another use-case is: open-source software where you want to encourage users to just open up "the damn code engine" and hack straight into it, seeing it change on the fly. Like, can you just right click in Windows on a pixel and change the code that underlies it? In Pharo you can! Commercial parties would find this horrible, but it's amazing for full open-source software.
For web apps, B2B works quite well. B2C, I see scalability issues.

Rust: Box Is a Unique Type
If you have an object that's !Unpin, then Miri will not apply uniqueness rules to anything containing it [0], including boxes and &mut references. (In the example code, replacing the PhantomPinned with a () will make Miri complain again.) This is considered a temporary (if long-lived) measure to allow async executors to manipulate pinned futures without invalidating all their references and whatnot. Thus, it might be seen as undetected UB, in lieu of a permanent solution.

Fivefold Slower Compared to Go? Optimizing Rust's Protobuf Decoding Performance
That would be true if you used `Vec::clear` too, it doesn't allocate a new vector. My point was that you still end up running Drop implementations with RepeatedField, just not all at once. See https://play.rust-lang.org/?version=stable&mode=debug&editio...

How to Lose Control of Your Shell
That's a valid Unix path, but rust's quoting does nothing to stop it: https://play.rust-lang.org/?version=stable&mode=debug&editio...

Borrow Checking Without Lifetimes
Self-referential structs work fine in Rust and always have.
https://play.rust-lang.org/?version=stable&mode=debug&editio...
The compiler will correctly prevent you from moving the value.
The other way to have a struct that starts out as non-self-referential and then becomes self-referential can be achieved with `unsafe` and `Pin::new_unchecked`, which is how `async {}` is handled.

Improving Interoperability Between Rust and C++
In rust as currently stands: https://play.rust-lang.org/?version=stable&mode=debug&editio...
On the other hand, both this wrapper and yours are counterproductive if the element size is dynamic (e.g. perhaps you're dealing with some nonsense like:)

New Linux glibc flaw lets attackers get root on major distros
Overflow checks turn into two's compliments' wrapping, but that's only considered acceptable because bounds checks are not turned off.

Atomics and Concurrency
I have no idea what you're talking about, but it sounds unnecessarily complicated and why I don't use Rust for any serious work.
This demonstrates the ABA problem in safe Rust: https://play.rust-lang.org/?version=stable&mode=debug&editio...
Substitute the sleep with a combination of doing computation/work and the OS thread scheduler, and you can see how the bug surfaces.
