gentoo-on-rpi-64bit VS nix

You're probably thinking of the now unmaintained https://github.com/sakaki-/gentoo-on-rpi-64bit. He took a %dayjob% that required him to stop committing to open source projects or, possibly, just

64 bit with gentoo i think is slightly less supported; but that is just from me looking around the package archive, and what it appears to be from the wiki. Though i am in the process of taking sakaki's 64 bit image and moving it over to use the official gentoo repos, so i guess i am glutton for punishment

Last time I was looking into this, no normal 64-bit rpi distro (including alarm) supported it. There was only gentoo that somebody hacked together offering mmal interface for h/w codecs: https://github.com/sakaki-/gentoo-on-rpi-64bit

You can build a binary distro based on Gentoo, e.g. https://github.com/sakaki-/gentoo-on-rpi-64bit (sadly EOL'ed several months ago).

Anyway, from my own experience, the video decoding performance of gentoo-on-rpi-64bit was somehow nowhere close to LibreELEC, on the same hardware. Perhaps there is a lesson to be learnt there...

yes. use gentoo. specifically this version: https://github.com/sakaki-/gentoo-on-rpi-64bit

This is very encouraging—I'm doing the same thing eventually on my Surface Pro (2017 model). Right now, I've just got it on a raspberry pi 4B 8GB. It works amazingly there, but I'm using a binary-heavy overlay and dwm. Firefox works better than I expected, but I haven't bothered with sound much, so I don't watch any video or anything. Also, the image I use (I use the “lite” variant available there) comes with an easy-to-use update tool (“genup”). At the very least, I consider it a great way to get acquainted with a significant portion of the Gentoo experience.

(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!)

((But you're a bright person, you have Google and ChatGPT to assist you, and you like challenges!))

Semi-related, I would recommend to anyone who is a Linux native to try to find some kind of "minimum viable setup" that is really really easy for you to run out of VirtualBox or Parallels or something for this reason. No matter where you go, you know you can have a suite of tools which work just as you want them to there. Being able to tear it down and rebuild it quickly is also a great way to deal with debugging certain kinds of problems of the "it runs/doesn't run on my machine" category.

How you do this is of course up to you. At one end of the spectrum is just relying on your memory. At the other end is using NixOS https://nixos.org/ to get fully reproducible builds anywhere you go. Between these are a vast field of options. I know a guy who maintains an Ansible file set to `host: localhost` which installs everything he wants from that file. For me, I just stick with the latest Ubuntu version and maintain a few shell scripts [1] that install 80% of what I like to have on a new install.

If you like the scientific approach, you can install something like https://atuin.sh/ and do some statistics on what programs you actually run most frequently based on your long term shell history.

See https://github.com/NixOS/hydra/issues/838 for making content-addressed derivations supported by hydra.nixos.org. At that point, we can actually try out the XP feature at scale.

Also see https://github.com/NixOS/nix/issues/8919 for this accepted RFC

Once those things are done, we can get back to merging in the IPFS code.

Now that there is an Nix team and I am on it, there is much, much less of an issue of these experiments being caught in limbo :).
