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.

Hack Lang: Contexts and Capabilities
Learned of this in https://news.ycombinator.com/item?id=37186869 it was posted 2 years ago to no discussion https://news.ycombinator.com/item?id=30291459 seems far more interesting than that.
https://github.com/facebook/hhvm/blob/master/hphp/hack/doc/H... appears to be where it was proposed, and has more background than the current docs.
- Has Meta/Facebook stopped developing hacklang?
-
Hacklang is no longer opensource?
also fredemmott is not working on it any more https://github.com/facebook/hhvm/issues/9376

Interesting ocaml mention in buck2 by fb
Hack and Flow are also written in OCaml.

Buck2, a large scale build tool written in Rust by Meta, is now available

Taking Hack Seriously - Slack Engineering
Compared to PHP, with its visible community, Hack/HHVM does seem like a dead-end technology. But it’s very actively maintained and it powers the largest website on the planet. It definitely doesn’t make sense for the average PHP developer to switch (and the article steers clear of evangelising) but it also definitely doesn’t make sense for us to switch back.

PHP is nearly as old as the web. Change the conversation and say: I use Hack on the Hip Hop Virtual Machine

RFC: Add large language models to Rust
https://github.com/rust-lang/rfcs/pull/3603
- Rust to add large language models to the standard library
-
Why does Rust choose not to provide `for` comprehensions?
Man, SO and family has really gone downhill. That top answer is absolutely terrible. In fact, if you care, you can literally look at the RFC discussion here to see the actual debate: https://github.com/rust-lang/rfcs/pull/582
Basically, `for x in y` is kind of redundant, already sorta-kinda supported by itertools, and there's also a ton of macros that sorta-kinda do it already. It would just be language bloat at this point.
Literally has nothing to do with memory management.

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:

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.

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].
