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.

20 Years of Nix
As far as I know, it’s still about [0]. I’ve had a better experience with deploy-rs though [1] - or even just using nixos-rebuild to target the remote machine.

Will we move away from DSLs?
For example Nix can already replace ansible, packer, cloudformation[1], dockerfiles.

NixOS History and Our Experience - Nix, Null, Nada, Nothing
Nix can also ship the nixpkgs as an oci image (e.g. docker image), vm image, iso, or if you're able to: as a nixos configuration. Tools like nixops can allow you to deploy many machines and have their behavior exactly specified, and the configuration can be version controlled. NixOS configuration can be thought of as congruent configuration management, where many other tools give you many less guarantees about configuration drift and reproducibility.

The best solution for deploying flakes
There are 4 tools I'm taking into consideration right now, but every suggestion is welcome: 1. deploy-rs - I don't know anything about it, heard about it like a day or two ago 2. NixOps - the official one, I don't know what to think, but I have concerns about Flakes compatibility 3. morph - I understand this as "NixOps, but better", no more toughs. 4. colmena - seems to be pretty straightforward with quite nice docs

Spectrum OS: a declarative, reproducible, compartmentalized Linux
I'm still relatively new to NixOS, having switched all my personal systems over to it this spring/summer. I don't have a detailed answer to your question, but I believe NixOPs is the canonical way to do what you're describing in production/at scale:

NixOS 21.05 Released!
Well, everyone of course! But especially devops, developers, power-users, and ricer folks. Due to the declarative and purity aspect of nixpkgs, all builds and configurations can be version controlled, cached and shared. NixOS can easily be extended to produce docker images, vm images, or even distributed deployments. You can also write reproducible multi-node integration tests. Tinkerers! Love playing around with the latest desktop manager or modifying builds? Nixpkgs allows you to modify any package you wish to, locally! Nixpkgs is actually a source distribution but its guarantees around purity and reproducibility are so strong that you can get a binary cache "for free".

Backblaze Is Now a Terraform Provider
You could use NixOps[0] for Nix but I'm not sure you can directly compare Terraform and Guix/Nix? My set up involves Terraform for infrastructure and Nix for provisioning, and it's working for me so far.

Benefits/disadvantages of Guix System in general and over NixOS?
I'll have to read more about NixOps though, I had kind of forgotten that it existed!

NixOS Linux
Kind of off topic, but I would love to have NixOps (https://github.com/NixOS/nixops) as an abstraction layer for every type of cloud service, and not just virtual machines (e.g. queues, object storages, etc).
There is Terraform and Ansible, of course, but Nix seems like it could combine the strengths of both of them.

A treatise on Nix
Yes, you can "hold on", it's called gcroots. There's lorri which you can also use to defer the tediousness of managing the gcroots to a daemon.

Per process memory and CPU usage control
Not that I know of but if you are having trouble with rebuilding and running out of memory, maybe the solution would be to cache the builds locally? You could use lorri to cache your development builds (https://github.com/target/lorri).

NixOS Linux
> Using a special command (nix-shell) whenever I needed to do development things (e.g. Rust builds) was not my idea of fun.
Funny you should mention that, because that's exactly what got me using Nix everywhere :). I've always hated installing tools and libraries globally—what if I need a different version for a future project?—so I like tools that sandbox as much as possible like virtualenv, cargo, cabal... etc. But these tools are all language-specific and have their own limitations (especially around native libraries and dependencies written in other languages).
nix-shell gives me the equivalent of virtualenv that works for everything. I can have a single sandboxed environment even if my project uses a bunch of different languages and I can manage everything in a reproducible, low-overhead fashion. No more worrying about making a mess by installing tools or packages globally.
Then, once I got really used to that, I spent some time setting up direnv[1] and lorri[2]—both of which are themselves managed with Nix, of course!—so that my environment gets automatically configured as soon as I enter a project directory without needing to call nix-shell explicitly. To be honest, the experience is still a bit rough, but it works well enough day-to-day that I have my reproducible sandbox cake and eat it in an mostly frictionless way too :).

What are some alternatives?
deploy-rs - A simple multi-profile Nix-flake deploy tool.
direnv - unclutter your .profile
terraform - Terraform enables you to safely and predictably create, change, and improve infrastructure. It is a source-available tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.
