My Julia Megarepo

This repository contains my simulation course exercises and other experimentations. I am generally using it as my Julia scratchpad. I’ll refactor out some of its parts when I should have the time.

The things of interest in it currently include:

An elaborate infectious disease model (which is remarkable in that it runs in a continuous mode, unlike most simulations that run in discrete steps)

Quickstart: The Infectious Disease Model

You need Julia v1.5 installed. You can copy my environment from this commit. The .julia directory needs to be in your HOME directory (i.e., at ~/.julia).

The model was tested with this commit, though I recommend just using the latest commit. Do not use the readme from that commit, always use the latest master commit for the readme.

Go to the project directory: cd ./project/
Start a Julia REPL: julia
Source the code: include("./prj.jl")
Now you can run the models. There are a few sample runs with the command that runs them in the project’s Telegram channel, since Github doesn’t show videos. I have also included a few screenshots below.

A happily-colored ising model

The code is at exercises/ising.jl. The generated pictures and videos are at art/ising/.

An image redrawing filter using Poisson processes

The code needs refactoring, it’s currently at line 108, @plot drawP2D(G=(λ) -> imgrate …. You can see examples at art/2d/. Most generated files have the code that generated them as their filename, or in a companion file with the same name as them. These code fragments might still have used an older API or a global variable, so they might not be copy-pasteable.
