> What distro package manager is allowing me to give a project newbie a single command to hit the ground running across all platforms Nix (it's the "distro package manager" of NixOS, but runs happily on any Linux distro, without even needing root permissions; it's also supported on macOS. I've seen references to other Unix systems like BSD, for WSL, and possibly other OSes, but they aren't officially supported). In fact, we don't even use "a single command"; our projects have .envrc files for direnv (which has Nix support out-of-the-box), so our shells automatically enter/exit a (reproducible) development environment just based on their current working directory. > "docker-compose up" I wasn't aware that Docker was cross platform? I thought it used Linux containers, which requires running a VM on macOS, etc. (e.g. that's what applications like "Docker Desktop" do in the background). Apparently it also supports "Windows containers" now, but those aren't even compatible with the Linux ones! > What distro package manager is allowing me to have several different platforms that can just grab a GitHub repo link and deploy it viola? Nix does this with a built-in function called `fetchGit` (there are also specialised functions like `fetchFromGitHub` and `fetchFromGitLab` which download the tar.gz of a given commit, rather than checking-out the repo). "Deployment" varies, depending on what you want; e.g. it could be a simple 'nix-copy-closure' (to a physical machine, a running VM, etc.), it could be making a container image (with a call to `ociTools.buildImage`, `dockerTools.buildImage`, etc.), or a VM image (VirtualBox, libvirt or Xen). NixOps and Disnix can orchestrate and deploy those, but I've not tried them (we use AWS ECR and CloudFormation).
