Reddit’s most hateful subs, or subs most hated by r/AgainstHateSubreddits

I’ve always been interested in the ever dynamic classification of hate on Reddit. As the post modernist set of moralities continues to expand, more and more subjects, ideas, and opinions become taboo. A growing creep of egg shells in Reddit’s ecosystem. One particular subreddit spearheads the outrage operations: /r/AgainstHateSubreddits.

It being a new year, I wanted to get a clearer picture of the sub’s current targets. So I wrote a quick script to parse out all subreddits names from hot post titles and created a simple wordcloud. Font size emphasis is increased by frequency of occurrence.

Reddit’s Most Hateful Subs of 2019

Double Pendulum and More Simulations

Unless the initial conditions are identical, they never swing the same.

The video below, displays a variety of chaotic blooms.

Initial Conditions for one of the scenes.

Gravity Simulations with Particle Streams

A compilation of gravity force simulations. Animations show what happens to a stream of particles when the force of gravity changes, or the source of gravity moves. These simulations were baked using Blender’s physics system.

Flower like shapes and interesting stream knots can be seen forming in the video below.

Fluid Resolution Differences in Blender 2.79

A video compilation showing how fluid behaves at different resolutions. These clips were rendered using the cycles engine in blender 2.79. Two distinct structures were created for the fluid simulations.

Close Packing Defect Formations of Equilateral Spheres

I made some animations of crystallographic defect formations using equilateral spheres. Point defects, lattice regions, and other interesting patterns can be seen forming in the video below. This was created using Blender’s rigid body physics system.

Visualizing Project Euler Laserbeam Problem 202

Below is an animation of a laser bouncing around a triangle with open vertexes. A link to the Euler problem can be found at projecteuler.net/problem=202. This is just a visualization of the problem. This post does not contain an answer, or any algorithms.

Map of Chicago created by Traffic Crashes 2016 – 2018

Point and heat maps of Chicago created by plotting coordinates of traffic crashes. Time range used, spans from January 2016 through September 2018. The data can be found at data.cityofchicago.org.

Crash data shows information about each traffic crash on city streets within the City of Chicago limits and under the jurisdiction of Chicago Police Department (CPD).

Subreddit Relationships by Mods (The_Donald, AgainstHateSubreddits, and TheBanOut2018)

I thought it would be interesting to see how specific subreddits are related to one another by their mods.

Here is an example of a single mod to many sub relationship.

Three root subreddits where chosen: r/The_Donald, r/AgainstHateSubreddits, and r/TheBanOut2018. Below are wordclouds showing what other subreddits share the same mods as the root subreddit. The font size is the scale for how many mods from the root sub are in another sub. The larger the font, the more mods they share with the root sub. For AHS and TheBanOut2018 clouds a mod relationship less than 4 where filtered out.

Chicago Gun Commissioned Robberies Batteries and Assaults – 2010 through 2018

A visualization of gun related incident reports from the Chicago Police Department. Primary crime types of robbery, battery, and assault with the use of a handgun. Time range used 2010 through 2018. To get access to the data, visit here https://data.cityofchicago.org/
