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
> I tried to install NixOS using the live cd last week in a Hyper-V VM, but it failed to get anywhere due to SquashFS errors.
Heh, that reminds me of installing NixOS back around 2014. I didn't have any way to physically boot off the install CD; so I ran it in qemu, using my real /dev/sda as the "virtual" hard drive (which I'd already partitioned). Thankfully there was no interference with the host system (Trisquel).
I'm still using (and evolved version of) the same NixOS config to this day; it still contains the following comment ( https://github.com/Warbo/nix-config/blob/master/nixos/machin... ):
trace "FIXME: Which modules are artefacts of using QEMU to install?"

The Curse of NixOS
Where nixpkgs2105 is a pinned revision of the Nixpkgs repo, defined in another overlay. My current Nix config has pinned Nixpkgs versions going back to 2016. For example, here's a bunch of such overrides:
https://github.com/Warbo/nix-config/blob/master/overrides/fi...
At the moment I'm using niv to manage the pinned Nixpkgs versions (the 'repoXXXX' entries):

Ask HN: Best Alternative to Homebrew in 2021?
`nix-env` is an imperative command, whilst writing a .nix file is declarative. In particular, the latter can be managed using git.
For example, here's a system-wide config dating back to Feb 2015: https://github.com/Warbo/nix-config
(That's actually a NixOS config; my macOS config is in a private repo, but it imports that repo to define its "one big system package")

I've used Nix/NixOS for about 8 years, but not delved into flakes yet.

NixOS RFC 136 accepted: A plan to stabilize the new CLI and Flakes incrementally
Yes, to get Nixpkgs it's much faster to use `fetchTarball`.
You're right that `builtins.fetchTarball` is faster than `builtins.fetchGit` (due to the ridiculous amount of commits in the Nixpkgs repo). I like to keep such definitions in a single, company-wide/project-agnostic git repo (what the Nix Pills series calls the "repository pattern"), and have individual projects import them via `builtins.fetchGit`.
Many years ago we didn't have `builtins.fetchGit`, so had to use the 'fetchgit' function from Nixpkgs instead. That created a chicken-and-egg situation if we wanted to take the Nixpkgs version from some other git repo; hence needing to "bootstrap" via `(import { config = {}; }).fetchgit`, and cross our fingers that `NIX_PATH` wasn't set to some crazy value (which, of course, I would inevitably do... https://github.com/Warbo/haskell-te/blob/24475a229908caa3447... )
Note that we need `config = {};` when importing Nixpkgs to avoid an impurity which tries to read files in $HOME. More recent versions of Nixpkgs also need `overlays = [];` to avoid another impurity (looks like this changed at Nixpkgs 17.03, according to https://github.com/Warbo/nix-helpers/blob/master/nixpkgs.nix )
