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.

Tvix – A New Implementation of Nix
(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.)

Colima k8s nix setup
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.

NixOs - Your portable dev enviroment
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?

Nix – A One Pager
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.

Tools for Linux Distro Hoppers
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.

Ask HN: Could Nix make crypto mining more efficient?
- 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?

Go + Hypermedia - A Learning Journey (Part 1)
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

Nixing Technological Lock In
"Your greatest challenge lies ahead -- and downwards..."
Oh, wait a second, my bad, that's the quote on the box cover for Zork I: (
https://upload.wikimedia.org/wikipedia/en/a/ac/Zork_I_box_ar...
https://en.wikipedia.org/wiki/Zork
)
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!))

What it was like working for Gitlab
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.

Cloudflare R2-Backed Nix Binary Cache on Fly.io
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 :).

How about converting it to Nix derivation?

Poetry2nix: mismatch cryptography sha256 but unable to modify
This looks really strange because I do not know how to solve it and also because it looks like the sha256 that I am setting is not the one that Nix will match. I read also https://github.com/nix-community/poetry2nix/issues/413 but I was not able to solve the problem.

As if there weren't enough packaging tools already: mitsuhiko/rye: an experimental alternative to poetry/pip/pipenv/venv/virtualenv/pdm/hatch/…
There's a project that does this with using Nix: https://github.com/takeda/nix-cde (this is a wrapper around https://github.com/nix-community/poetry2nix)

Setting up Stabe Diffusion on NixOS
A cleaner way might be to use https://github.com/nix-community/poetry2nix which can load poetry.lock inside Nix. I still need to try it for torch, but it does seem like a clean way to use it.
