cargo-raze VS nix

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.

See:

- https://github.com/bazelbuild/rules_rust

- https://github.com/google/cargo-raze

I can make much more sense of C++ code to ensure that two build systems produce the same effect than I can parse and learn two completely unconnected programming languages deeply enough to do the same. I can unit-test core routines. I can as easily extract core logic into shared (configuration) files etc. The benefit of a standard is not to discourage alternatives but rather to agree on definitive semantics and shared and common needs (that is: in this case needs for interfaces to the compiler/linker). The implementation and general availabilty is just one of the by-product. The ability to do introspection in common terms is maybe the most consequential other product, and this is critical for 'transpiling' to other build systems and writing automated adapters such as the one that bazel is recommend for cargo's dependency management.

Cargo is not that tightly coupled with Rust. You can absolutely use bare rustc, and in fact people do that with other build systems like Bazel.

Interesting, aren't the community-driven crates for these areas satisfactory enough? There's PROST and tonic, and quite well-used. I don't know about Bazel though, but I found this. Feel free to correct me on this subject, I admit I don't know that much about it.

There is a project to generate Bazel BUILD files from Cargo.toml.

As we covered in my last post, NixOS is a amazing Linux distribution for creating stable and declared environments. Now while this is amazing for a desktop setup, it is also perfect for a home-server or home-lab.

(Nix itself is slowly chugging along with Windows via MinGW - https://discourse.nixos.org/t/nix-on-windows/1113/108 and https://github.com/NixOS/nix/issues/1320 , for example.)

Nix is a cross-platform package manager. It uses the nix programming language. Nix and NixOs are often used in the same context, but while the first is a package manager, the latter is a linux distribution based on nix.

Today I want to talk to you about Nixos. What is it? Nixos is a declarative and reproducible OS, partly taking the words used on their own page. What does that mean?

Software developers often want to customize:

1. their home environments: for packages (some reach for brew on MacOS) and configurations (dotfiles, and some reach for stow).

2. their development shells: for build dependencies (compilers, SDKs, libraries), tools (LSP, linters, formatters, debuggers), and services (runtime, database). Some reach for devcontainers here.

3. or even their operating systems: for development, for CI, for deployment, or for personal use.

Nix provision all of the above in the same language, with Nixpkgs, NixOS, home-manager, and devShells such as https://devenv.sh/. What's more, Nix is (https://nixos.org/):

- reproducible: what works on your dev machine also works in CI in prod,

- declarative: you version control and review your configurations and infrastructure as code, at a reasonable level of abstraction,

- reliable: all changes are atomic with easy roll back.

Hopping from one distro to another with a different package manager might require some time to adapt. Using a package manager that can be installed on most distro is one way to help you get to work faster. Flatpak is one of them; other alternative are Snap, Nix or Homebrew. Flatpak is a good starter, and if you have a bunch of free time, I suggest trying Nix.

- it reduces bloat, because you can generate an environment or OS image with only the software needed to run a specific program or service

My guess is that a big efficiency gain would come from the second point, because you don't waste CPU on code that you don't use.

Does this make sense? Has anyone explored this?

1) Setting up the development environment - I currently use devcontainers for most things, but may also dig into nix -> isolated, portable, repeatable development environment 2) Exploring Echo - understand routing, requests, response, etc. 3) Incorporate Templ - integration with Echo, template composition, etc. 4) Integrating TailwindCSS - config for use with Echo/Templ, development cycle, deployment, etc. 5) Add in HTMX - endpoints, template structure, concepts, etc. 6) hyperscript for interactivity - client side interactivity

Oh, wait a second, my bad, that's the quote on the box cover for Zork I: (

What you really wanted was a link to where you could download Nix/NixOS -- and/or learn more about it!

Here ya go!

"Your greatest challenge lies ahead -- and downwards..."

:-) :-)

I say all of the above in the spirit of humor -- and as a NixOS user and fan!

(But yes, there is a learning curve to it, so yes, learning Nix/NixOS could be a challenge!)
