Fast, Declarative, Reproduble and Composable Developer Environments Using Nix
I gave devenv multiple tries, and I am sorry to say there are multiple annoying issues that forced me to give up every time.
Some of these 200+ issues are unsolved for a fairly long time.

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.

Show HN: Lapdev, a new open-source remote dev environment management software
https://devenv.sh/ and nix in general are great for setting up dev environments.

Show HN: Flox 1.0 – Open-source dev env as code with Nix
> but worried that the development is not moving forward
There is an open v1.0 PR: https://github.com/cachix/devenv/pull/1005

What's the Next Vagrant?
2) A way to run services apps depend on (databases, job runners, cache etc).
I am going to suggest one of the Nix based tools that do those things:
- https://devenv.sh/ (I use this at work)

Ask HN: How can I make local dev with containers hurt less?
Yup, I haven’t tried it but there is https://devenv.sh which is built on top of nix and makes it simple.

Flakes aren't real and cannot hurt you: using Nix flakes the non-flake way
Although Guix reads better than Nix (after all, it's Lisp), I found the support and resources available for learning severely lacking.
Plus, you have to jump through hoops to install non-free software, which goes against the ethos of Guix anyway.
IMHO, Nix is clearly "the winner" here and we'll see more and more adoption as it improves. Lots of folks are doing exciting work (see https://determinate.systems/, https://devenv.sh/, https://flakehub.com/). And the scale and organization around nixpkgs is damn impressive.

NixOS has one fatal flaw
I don't think you can ever get Nix as simple as PNPM, simply because native libraries are sometimes annoying, need to be configured at build time to a greater degree and because the problem space it attacks is so much larger than PNPM, which only deals with the JS/Node.js ecosystem.
However, I do think that there exist reasonable levels of abstraction that sacrifice some expressive power for simplicity and such systems could maybe expose a PNPM-like CLI. One example that comes to mind is devenv.nix [1]. While it doesn't yet have a CLI, its configuration file is YAML and relatively simple. I think there's more to be done in this space and I hope for tools that are easier to grasp in the future.
> Nix package files evaluate down to configuration for the Nix package manager, but I haven’t ever seen a good explanation for the basic essentials underneath all the abstraction. Every guide I’ve learned from and all the package defs I’ve read seem to cargo cult many layers of mysterious config composing config. Without easy to learn essentials it’s difficult to grok the system as a whole.
To me it sounds like the essential that you're referring to is the 'derivation' primitive, which is almost always hidden behind the mkDerivation abstraction from nixpkgs. This [2] blog post is an exploration of what exactly that means.
I'd also love for the documentation situation to be much better, in particular in terms of official, curated resources. But I'm not convinced that you actually need to know the difference between derivation and mkDerivation to make effective use of Nix, because in practice you would always use the latter. That said, mkDerivation and the whole of nixpkgs is essentially a huge DSL (I believe this is what you meant when you said 'config composing config') that you do need to know and is woefully underdocumented.
> I would love to adopt Nix for developer tooling for Notion’s engineers, but today it’s about infinity times easier to work around the limitations mentioned of Docker+Ubuntu+NPM than to work around the limitations of Nix.
One approach I have taken to is to specify the environment in Nix, but then generate Docker devcontainers from it, so most people don't come into contact with Nix if they don't want to.

Development Environments with Guix, similar to devenv.sh
This though, through the use of devenv.sh, which uses nix, as when I got into nix I though it was going to be easier to just make a development environment, not the case. Until I found devenv.sh, I could actually finally make good environments... It also has other features like containers and services, which also help me know that I can get the most of it if the time comes.

I use NixOS for my home-server, and you should too!
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.

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?

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

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!)
