Guix on WSL2

(updated versions of this document, plus more, live here)

This will show you how to get Guix running on WSL2.
We're going to go as "minimal" as possible, without starting off one of the readily available WSL2 distros.
Parts of this guide should help with understanding how to set up any custom distro on WSL, not just Guix.

Disclaimer: I'm a Guix nOOb! (hence going through the trouble of installing it on WSL2)

// Creating a node graph editor for Dear ImGui
// Quick sample, not production code! 
// This is quick demo I crafted in a few hours in 2015 showcasing how to use Dear ImGui to create custom stuff,
// which ended up feeding a thread full of better experiments.
// See https://github.com/ocornut/imgui/issues/306 for details

// Fast forward to 2023, see e.g. https://github.com/ocornut/imgui/wiki/Useful-Extensions#node-editors

// Changelog
// - v0.05 (2023-03): fixed for renamed api: AddBezierCurve()->AddBezierCubic().

[JULIA] Faster than CGAL Delaunay

TL;DR

DelaunayJL is an incremental 2D Delaunay triangulation algorithm implemented in Julia, it is robust and ~20% faster than CGAL, the C++ de-facto industry standard. And it's MIT Licensed! all links to code are below

Show me the data!

The figure below shows how much time it takes to run a benchmark on my computer, an Intel Core i7-4800MQ CPU @ 2.7Ghz, 16GB RAM, Win8 64bit. The benchmark consists of inserting a number of points uniformly distributed. The benchmark is run 5 times for each number of points once for CGAL and once for Julia. The numbers of points used are 10K, 100K, 1M, and 10M. CGAL v4.4 was compiled with VS2013 64bit release mode, Julia is of version 0.3.0 Commit 7681878 (2014-08-20 20:43 UTC) x86_64-w64-mingw32 the delaunay code is here (see other gists of mine for complementing files... I'll compile this all into a library when I have the time)

(* How do to topology in Coq if you are secretly an HOL fan.
   We will not use type classes or canonical structures because they
   count as "advanced" technology. But we will use notations.
 *)

(* We think of subsets as propositional functions.
   Thus, if [A] is a type [x : A] and [U] is a subset of [A],
   [U x] means "[x] is an element of [U]".
