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.

The KDE desktop gets an overhaul with Plasma 6
I would suggest that nearly every person on this website is a developer. Both C and C++ let you shoot yourself in the foot quite easily, but at least C++ has RAII.
If you're referring to Rust, it's just not there yet for anything serious: https://areweguiyet.com/

Ask HN: Rust Viable for Data Analytics?
I normally use python to do some quick data analysis, with pandas/polars/pyspark/...
But I've started to use rust more and more in the last few weeks and really start to like it.
Does anyone have experience doing data analysis with rust, and would you recommend it over python?
And are there any resources like https://areweguiyet.com/ but for data analysis?

On inheritance and why it's good Rust doesn't have it
You still haven't said anything about why those existing frameworks don't count. Again, they are used in production and do exactly what a gui framework is supposed to do. Sure they may not have all the features of the frameworks that have existed a decade before rust even existed but the issue is time not rust itself. They very clearly can be used to build complex UI without inheritance. Since you mentioned it, you should probably actually look at it https://areweguiyet.com/ the page clearly says that GUI frameworks do exist in rust.

BeeWare Toga v0.4.0 – A Python native, OS native GUI toolkit
The web site https://areweguiyet.com/ has a list of GUI libraries for Rust.
I haven’t tried any yet as I lack the time, but it can be a good starting point.
Iced and Slint where interesting when I looked at that, and Slint may be done by former Qt developers.

Learn graphics for theoretical gui with rust
I also hope that it is consistent with the goals mentioned at https://areweguiyet.com/
- Are We <Thing> Yet?
- Is it possible to build a gui which is both cross compatible and native?
-
Can someone explain in layman's terms what is the deal with the GUI Framework for Rust?
There is research being done, people are working on architectures based on the ELM architecture (check areweguiyet.com for more) and reactive ones, but I haven't had a very good experience out of them yet.

Announcing concoct! A cross-platform native UI framework (formerly viewbuilder)
Very nice! Hoping to see this on https://github.com/areweguiyet/areweguiyet ;-)

Uv: Python Packaging in Rust
Congrats!
> Similarly, uv does not yet generate a platform-agnostic lockfile. This matches pip-tools, but differs from Poetry and PDM, making uv a better fit for projects built around the pip and pip-tools workflows.
Do you expect to make the higher level workflow independent of requirements.txt / support a platform-agnostic lockfile? Being attached to Rye makes me think "no".
Without being platform agnostic, to me this is dead-on-arrival and unable to meet the "Cargo for Python" aim.
> uv supports alternate resolution strategies. By default, uv follows the standard Python dependency resolution strategy of preferring the latest compatible version of each package. But by passing --resolution=lowest, library authors can test their packages against the lowest-compatible version of their dependencies. (This is similar to Go's Minimal version selection.)
> uv allows for resolutions against arbitrary target Python versions. While pip and pip-tools always resolve against the currently-installed Python version (generating, e.g., a Python 3.12-compatible resolution when running under Python 3.12), uv accepts a --python-version parameter, enabling you to generate, e.g., Python 3.7-compatible resolutions even when running under newer versions.
This is great to see though!
I can understand it being a flag on these lower level, directly invoked dependency resolution operations.
While you aren't onto the higher level operations yet, I think it'd be useful to see if there is any cross-ecosystem learning we can do for my MSRV RFC: https://github.com/rust-lang/rfcs/pull/3537
How are you handling pre-releases in you resolution? Unsure how much of that is specified in PEPs. Its something that Cargo is weak in today but we're slowly improving.

The bane of my existence: Supporting both async and sync code in Rust
In the early days of Rust there was a debate about whether to support "green threads" and in doing that require runtime support. It was actually implemented and included for a time but it creates problems when trying to do library or embedded code. At the time Go for example chose to go that route, and it was both nice (goroutines are nice to write and well supported) and expensive (effectively requires GC etc). I don't remember the details but there is a Rust RFC from when they removed green threads:
https://github.com/rust-lang/rfcs/blob/0806be4f282144cfcd55b...

Why stdout is faster than stderr?
I did some more digging. By RFC 899, I believe Alex Crichton meant PR 899 in this repo:
https://github.com/rust-lang/rfcs/pull/899
Still, no real discussion of why unbuffered stderr.

Go: What We Got Right, What We Got Wrong
Rust shares Go's "errors as values + panics" philosophy. Rust also has a standard library API for catching panics. Its addition was controversial, but there are two major cases that were specifically enumerated as reasons to add this API: https://github.com/rust-lang/rfcs/blob/master/text/1236-stab...
> It is currently defined as undefined behavior to have a Rust program panic across an FFI boundary. For example if C calls into Rust and Rust panics, then this is undefined behavior. Being able to catch a panic will allow writing C APIs in Rust that do not risk aborting the process they are embedded into.
> Abstractions like thread pools want to catch the panics of tasks being run instead of having the thread torn down (and having to spawn a new thread).
The latter has a few other similar examples, like say, a web server that wants to protect against user code bringing the entire system down.
That said, for various reasons, you don't see catch_unwind used in Rust very often. These are very limited cases.

Ask HN: What's the fastest programming language with a large standard library?
Rust has had a stable SIMD vector API[1] for a long time. But, it's architecture specific. The portable API[2] isn't stable yet, but you probably can't use the portable API for some of the more exotic uses of SIMD anyway. Indeed, that's true in .NET's case too[3].
Rust does all this SIMD too. It just isn't in the standard library. But the regex crate does it. Indeed, this is where .NET got its SIMD approach for multiple substring search from in the first place[4]. ;-)
You're right that Rust's standard library is conservatively vectorized though[5]. The main thing blocking this isn't the lack of SIMD availability. It's more about how the standard library is internally structured, and the fact that things like substring search are not actually defined in `std` directly, but rather, in `core`. There are plans to fix this[6].

Progress toward a GCC-based Rust compiler
Mara's blog post also describes the benefits of standardizing Rust.
Since she created the RFC for standardizing Rust (https://github.com/rust-lang/rfcs/pull/3355) and is also on the team that is working on Rust standardization (https://blog.rust-lang.org/inside-rust/2023/11/15/spec-visio...), I think she was making the point that Rust has good controls in place for adding features while compatibility, not that "Rust does not need a standard".
If she really believed that Rust does not need a standard, why would she create the RFC and join the team working on the effort?
Rust is a great language. There is no reason why it should not have a standard to better formalize its requirements and behaviors.
