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.

no_panic causing errors in hello world?
I discovered a crate called no_panic that prevents a function from compiling, unless the compiler can proof that this function can't panic.
-
Is there something like "super-safe" rust?
/u/dtolnay has a no-panic macro, I don't know its limitations but in older comments they note it pretty much has to be used in release mode, as there are lots of panic codepaths which get optimised out.

Is Rust really safe? How to identify functions that can potentially cause panic
'Hacks' such as https://github.com/dtolnay/no-panic, https://crates.io/crates/no-panics-whatsoever that ensure any calls to panic handling will result in link errors. Not really reliable in terms of being able to abort instead, but a possible tool.

US NGO Consumer Reports also reporting on C and C++ safety for product development.
nope. Unfortunately, no mainstream language has this yet. We need an Algebraic effects typesystem to do this properly. There are a few temporary band-aid solutions like https://github.com/dtolnay/no-panic

Carefully exploring Rust as a Python developer
This kind of already exists in the form of #[no_panic] [1]?
> If the function does panic (or the compiler fails to prove that the function cannot panic), the program fails to compile with a linker error that identifies the function name.

LKML: Linus Torvalds: Re: [PATCH v9 12/27] rust: add `kernel` crate
I really think that Rust needs an official #[no_panic] macro that can validate these sort of things (like dtolnay’s crate, I’m not sure why it was archived)

A pair of Linux kernel modules using Rust
Because it's convenient and familiar to most programmers. Not providing bounds-checked indexing makes some kinds of code very hard to write.
But note his problem also happens with integer division.
In Rust, a[x] on an array or vec is really a roughly a shortand for a.get(x).unwrap() (with a different error message)
Likewise, a / b on integers is a kind of a shortand for a.checked_div(b).unwrap()
The thing is, if the index ever is out of bounds, or if the denominator is zero, the program has a bug, 100% of time. And if you catch a bug using an assertion there is seldom anything better than interrupting the execution (the only thing I can think of is restarting the program or the subsystem). If you continue execution past a programming error, you may sometimes corrupt data structures or introduce bizarre, hard to debug situations.
Doing a pattern match on a.get(x) doesn't help because if it's ever None (and your program logic expects that x is in bounds) then you are kind of forced to bail.
The downside here is that we aren't catching this bug at compile time. And it's true that sometimes we can rewrite the program to not have an indexing operation, usually using iterators (eliding the bounds check will make the program run faster, too). But in general this is not possible, at least not without bringing formal methods. But that's what tests are for, to ensure the correctness of stuff type errors can't catch.
Now, there are some crates like https://github.com/dtolnay/no-panic or https://github.com/facebookexperimental/MIRAI that will check that your code is panic free. The first one is based on the fact that llvm optimizations can often remove dead code and thus remove the panic from a[x] or a / b - if it doesn't, then compilation fails. The second one employs formal methods to mathematically prove that there is no panic. I guess those techniques will eventually be ported to the kernel even if panics happen differently there (by hooking on the BUG mechanism or whatever)

Redoing the runtime
Hmm, yeah as you mentioned, looks like a surprising amount of stuff is already done in the rust for the linux kernel project: https://github.com/Rust-for-Linux/linux/tree/rust/rust/. It's also MIT/Apache licensed, but I was expecting gpl, so I can actually use it. It's still a lot to trim down on, so might be easier to just build up as needed. Additionally I just saw /u/dtolnay's #[no_panic] attribute which at least makes it a compiler error if it's accidentally done.

[PATCH 00/13] [RFC] Rust support
Obviously, in bare metal systems, in the kernel, etc, you always want to use the second style. In this patch series, the first type had been stubbed out to panic, but Linus doesn't want any chance of panicking, he wants it to be a compile time error if anyone tries to call these methods from within the kernel, for example by not providing the symbols and failing to link if someone did try to use them. There is already precedent for doing that in the Rust ecosystem, so it's planned to do that in this patch series, but the authors hadn't gotten to that yet.

Have you ever wanted a library to check for 69 in a string?
You can use Tensorflow for Rust to simplify that task and avoid pain with regex. Just have the right mindset.

Making a better Tensorflow thanks to strong typing
What is the benefit of this compared to using bindings/a wrapper to Tensorflow, or other ML libraries written in C/C++, such as this community hosted project on tensorflow's github. If it's just for fun that is a valid enough reason imo, just curious since you describe it as a better Tensorflow because of the typing vs using the python wrapper, when there already exist ways to interact with tensorflow with both Rust and other statically typed languages, also including C++ (officially supported), C#, Haskell and Scala, as well as probably having bindings not mentioned on the documentation for more niche languages.

Is PyO3 library production ready?
Thank you for the restponse! With tensorflow I am probably better of with something like; [tensorflow rust bindings](https://github.com/tensorflow/rust/tree/master/src). But I believe some useful extensions are still written in python for example; [TFDV](https://github.com/tensorflow/data-validation).. and how about scikit-learn or even something that is simpler like fb-prophet that is entirely written in python?

How mature is the QT integration?
Tensorflow bindings exist, technically, but they're in a pretty rough state AFAIK.
