Andrei Kashcha has developed a graphical map of reddit. Each dot on the map is subreddit. Two dots within the same cluster are usually close to each other if multiple users frequently leave comments on both subreddits.
I processed 176,178,986 unique comments that redditors left in years 2020 – 2021 and computed Jaccard Similarity between subreddits.
Then I treated relationships between subreddits as a graph clustering problem. Once clusters are computed, I treated them as a graph layout problem and created an SVG file. Once SVG file was created I treated it as a dual problem of WebGL rendering and streaming SVG parsing, and created my own webgl renderer and streaming svg parser.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
