Why Is This Site Built with C
Agree regarding easiness of building rust (`cargo build`), extremely satisfying (git clone and cargo build...)
Does anyone have any comments on Bazel[1] because I'm kind of settling on using it whenever it's appropriate (c/c++)?..

Chicory: A JVM native WebAssembly runtime
Chicory seems like it'll be pretty useful. Java doesn't have easy access to the platform-specific security mechanisms (seccomp, etc) that are used by native tools to sandbox their plugins, so it's nice to have WebAssembly's well-designed security model in a pure-JVM library.
I've used it to experiment with using WebAssembly to extend the Bazel build system (which is written in Java). Currently there are several Bazel rulesets that need platform-specific helper binaries for things like parsing lock files or Cargo configs, and that's exactly the kind of logic that could happily move into a WebAssembly blob.

Is NixOS truly reproducible?
> Bazel also obviously uses the system compilers and headers. Nix does not.
Bazel allows hermetic toolchains, and uses it for most languages: Java, Python, Go, Rust, Node.js, etc. You can do the same for C++, but Bazel doesn't provide that out-of-the-box. [1]
Bazel sandboxing can restrict system access on Linux with --experimental_use_hermetic_linux_sandbox and --sandbox_add_mount_pair. [2]
Every "reproducible builds" discussion requires an understand of what is permitted to vary. E.g. Neither Nix nor Bazel attempts to make build products the same for x86 host environments vs ARM host environment. Bazel is less aggressive than Nix in that it does not (by default) attempt to make build products the same for different host C++ compilers.

Rhai: An embedded scripting language for Rust
You can say that for everything, after all of it's turing complete you can do anything.
But practically, the difference is intention, which drives design and ecosystem.
E.g: starlark is very oriented toward idenpotence and limiting side effects to get reproducible config data. By default they discourage reading files: https://github.com/bazelbuild/bazel/issues/13300
But rhai is not particularly oriented toward config, and the doc promotes an extension to read files: https://rhai.rs/book/lib/rhai-fs.html
The tutorials, stdlib, language design anf tooling will all reflect this.

7 Ways to Use the SLSA Framework to Secure the SDLC
To achieve reproducibility, your build process must control for environmental differences like timestamps, file ordering, or machine-specific configurations. Tools like Bazel or Nixprovide deterministic build systems that lock down these variables. For instance, Bazel uses a content-addressable cache, meaning the same source code and dependencies always result in the same build outputs, even when run on different machines.

Contributing To Open Source - C++ Edition
Despite following all the steps (on both Windows and Unix), I couldn't get the cmake build to succeed. After several hours of debugging, I decided to try another build method provided by the project, using bazel, which was much simpler.

How to effectively work in big codebases
Many big companies have built their own tools to reign in this complexity and make it easier and faster for developers to work on large, multi-language code bases. Meta has buck, Amazon has brazil, and Google has bazel. But from my experience, especially, with brazil, these tools also have some rough edges, so understanding how they work can go a long way.
