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.

Cranelift code generation comes to Rust
Windows is supported. See https://github.com/rust-lang/rustc_codegen_cranelift/issues/....

A Guide to Undefined Behavior in C and C++
> When this happens, it seems like it'll be possible to get the LLVM bits out of the bootstrap process and lead to a fully self-hosted Rust.
What do you mean by "when this happens"? GP's point is that this has already happened: the Cranelift backend is feature-complete from the perspective of the language [0], except for inline assembly and unwinding on panic. It was merged into the upstream compiler in 2020 [1], and a compiler built with only the Cranelift backend is perfectly capable of building another compiler. LLVM hasn't been a necessary component of the Rust compiler for quite some time.

What are some stuff that Rust isn't good at?
Note that the Cranelift codegen will eventually become standard for debug builds to speed them up.

Rust port of B3 from WebKit, LLVM-like backend
Maybe one day we'll have rustc b3 backend like what they did with Cranelift

Any alternate Rust compilers?
Additionally, there is gcc codegen for rustc (https://github.com/rust-lang/rustc_codegen_gcc), which is not a compiler per se, but an alternative code generator, with more architectures supported and other nice things. It's also coming along, but there's still a lot of work to do there too. There's also Cranelift codegen (https://github.com/bjorn3/rustc_codegen_cranelift), which is designed to make debug builds faster, but this is not as exciting/useful as the other 2.

Capsules, reactive state, and HSR: Perseus v0.4.0 goes stable!
For the instant reloading, that's in Sycamore, so you should speak to its devs, but as for the alternative compiler backend, it's not my project, but it uses Cranelift and works pretty well! See https://github.com/bjorn3/rustc_codegen_cranelift for details.

Improving Rust compile times to enable adoption of memory safety
Cranelift is not used for debug builds by default. I think that's probably a goal (although I'm not actually 100% sure about that just because I'm not dialed into what the compiler team is doing). Even the OP mentions this:
> We were able to benchmark bjorn3's cranelift codegen backend on full crates as well as on the build dependencies specifically (since they're also built for cargo check builds, and are always built without optimizations): there were no issues, and it performed impressively. It's well on its way to becoming a viable alternative to the LLVM backend for debug builds.
And the Cranelift codegen backend itself is also clear about it not being ready yet: https://github.com/bjorn3/rustc_codegen_cranelift
(To be clear, I am super excited about using Cranelift for debug builds. I just want to clarify that it isn't actually used by default yet.)
The more immediate goal of "distribute the cranelift backend as a rustup component" has been making good progress and seems like it might happen relatively soon https://github.com/bjorn3/rustc_codegen_cranelift/milestone/...

Meta releases Sapling, a new way of using source control
Kind of weird that https://github.com/facebookexperimental/eden (linked in mononoke) redirects to sapling. Does that mean it's replacing eden?

We Put Half a Million Files in One Git Repository, Here’s What We Learned
Maybe at their scale it makes more sense to switch to a VCS like Eden? https://github.com/facebookexperimental/eden
Eden's equivalent of 'git status' should run almost instantaneous, as checkouts are hosted by a virtual file system (FUSE) that tracks changes.

Ask HN: What developer tools would you like to see?

Working on it :)
> - A version control system which scales to petabytes or more. Something that I could put large video files in without thinking twice about it. Something a large company could use for their monorepo—or even their data warehouse.

Eden
Hm. I can see why they'd build some of these features, but there's some significant downsides. The VFS in particular will end up a poor experience when a transitory network problem makes pulling the code hang apps.
On the build side.... holy jesus, are they really compiling 40 different dependencies from scratch every time they push code? This build has been running for 5 minutes and it's still just compiling dependencies: https://github.com/facebookexperimental/eden/runs/5997101905... Come on, ya'll. You're supposed to be the "advanced FAANG people". Cache some build deps, will ya?
The docs still refer to the the tool as Mecurial/hg:

Do you think Rust has a future in Backend Web Development?
Facebook's Mononoke has been their production monorepo since 2019. The "early stages of development" mentioned in the mononoke readme are regarding the work towards releasing this as open-source, without dependency on Facebook infrastructure.
