fix function - https://github.com/NixOS/nixpkgs/blob/9f087964709174424bca681b600af8ee8e763df5/lib/fixed-points.nix#L19 , https://en.m.wikipedia.org/wiki/Fixed_point_(mathematics) , point where x = f(x) = f(f(f(f....f(x)....)))

rec { a = 1; b = a + 1; } is the same as fix (self: { a = 1; b = self.a + 1; })

builtins.trace - https://github.com/NixOS/nixpkgs/blob/9f087964709174424bca681b600af8ee8e763df5/lib/debug.nix#L4 trace has different flavors, http://hackage.haskell.org/package/base-4.12.0.0/docs/Debug-Trace.html#v:trace all lazy languages have trace

builtins.seq - in lazy languages data is represented as thunks (IF data has not been yet evaluated THEN it's pointer on function that should produce this data ELSE it's pointer on data), builtins.seq forces first layer of data to evaluate (evaluates it to WHNF?), builtins.deepSeq is recursive variant of seq, it forces whole data to evaluate (evaluates it to NF?), (more https://wiki.haskell.org/Seq, https://www.google.com/amp/s/amp.reddit.

Nix Flake MVP

Goals

• To provide Nix repositories with an easy and standard way to reference other Nix repositories.

• To allow such references to be queried and updated automatically.

• To provide a replacement for nix-channel, NIX_PATH and Hydra

Multi user nix installation

Each section should be run as the user or as root, pay attention to which one!

Install nix single user

As $USER

Emacs packages, features, files, layers, extensions, auto-loading, require, provide, use-package… All these terms getting you confused? Let’s clear up a few things.

Files

Emacs files contains code that can be evaluated. When evaluated, the functions, macros and modes defined in that file become available to the current Emacs session. Henceforth, this will be termed as loading a file.

One major problem is to ensure that all the correct files are loaded, and in the
