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.

NixOS: Declarative Builds and Deployments
The same reason Bazel builds avoid using Cargo when building Rust software, so I'll describe why Bazel would do this:
- Bazel wants to cache remote resources, like each respective crate's source files.
- Bazel then wants to build each crate in a sandbox, and cache the build artifacts
This is an established practice, and Nix wants to drive the build for the same reasons.

Rust fact vs. fiction: 5 Insights from Google's Rust journey in 2022
To answer your question, I don't know if Soong or Bazel can reuse the files produced by an incremental Rust compilation. I tried searching the rules_rust repository and found some discussions, but nothing that clearly told me "Yes, this is supported".
-
When to Use Bazel?
Bazel doesn't allow targeting a lot of platforms (especially embedded) from Rust, even when the Rust ecosystem supports these targets. Something is off with its design if new work needs to be done for every platform that's already available behind an interface that's as consistent as what rustc gives.
What is supported needs to be inferred from this file, as far as I can tell: https://github.com/bazelbuild/rules_rust/blob/main/rust/plat...

Cpp-like build tools for Rust?
You might be overjoyed to learn that you can use a build tool that forces you to manually write out the dependencies between each file.

How to enable suggestions/autocomplete in VS Code?
I am using rules_rust and have the VS Code Bazel plugin installed, but I am still not getting autocomplete.

Blog Post: Fast Rust Builds
Other than that, the performance of both for builds should be determined exactly by the organization of code into separate crates and the rustc invocations. Bazel generally encourages smaller crates, but that's very subtle. There is at least 1 case I can think of where rustc is overfit to cargo, in a way that is not easily replicable by bazel, which is the metadata/rlib pipelining https://github.com/bazelbuild/rules_rust/issues/228

Modern C++ Won't Save Us (2019)
Rust integrates pretty seamlessly into Bazel projects via rules_rust (https://github.com/bazelbuild/rules_rust). The existing rules even allow for c calling rust and rust calling c. Example: https://github.com/bazelbuild/rules_rust/blob/main/examples/...

Why Zig When There Is Already C++ and Rust?
With any compiled language you can use the compiler and vendor your dependencies instead of using the language's conventional package manager. For example, nothing prevents skipping Cargo and building Rust directly with rustc the way Bazel does.

Programming from Top to Bottom - Parsing
You can never mistake type_declaration with an identifier, otherwise the program will not work. Aside from that constraint, you are free to name them whatever you like, there is no one standard, and each parser has it own naming conventions, unless you are planning to use something like LLVM. If you are interested, you can see examples of naming in different language parsers in the AST Explorer.

Look ma, I wrote a new JIT compiler for PostgreSQL
> There is one way to make the LLVM JIT compiler more usable, but I fear it’s going to take years to be implemented: being able to cache and reuse compiled queries.
Actually, it's implemented in LLVM for years :) https://github.com/llvm/llvm-project/commit/a98546ebcd2a692e...

C++ Safety, in Context
> It's true, this was a CVE in Rust and not a CVE in C++, but only because C++ doesn't regard the issue as a problem at all. The problem definitely exists in C++, but it's not acknowledged as a problem, let alone fixed.
Can you find a link that substantiates your claim? You're throwing out some heavy accusations here that don't seem to match reality at all.
Case in point, this was fixed in both major C++ libraries:
https://github.com/gcc-mirror/gcc/commit/ebf6175464768983a2d...
https://github.com/llvm/llvm-project/commit/4f67a909902d8ab9...
So what C++ community refused to regard this as an issue and refused to fix it? Where is your supporting evidence for your claims?

Rewrite the VP9 codec library in Rust
Through value tracking. It's actually LLVM that does this, GCC probably does it as well, so in theory explicit bounds checks in regular C code would also be removed by the compiler.
How it works exactly I don't know, and apparently it's so complex that it requires over 9000 lines of C++ to express:
