Managing auto-expanding archives via the ExchangeOnlineManagement module is a pain in my ass. This Github Gist is an aggregate of scripts I've written that allow me to administrate this mailbox feature effectively.

k-means clustering is a method of vector quantization, originally from signal processing, that aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centers or cluster centroid), serving as a prototype of the cluster. This results in a partitioning of the data space into Voronoi cells.

The Buddhabrot fractal is a type of fractal that is generated by plotting the paths of points that escape from the Mandelbrot set. The resulting image resembles a series of intertwined spirals and branches, and is named after the shape it resembles, which is said to resemble the seated figure of Buddha. The Buddhabrot fractal is created by assigning each point in the complex plane a "color" based on how many times it takes for that point to escape from the Mandelbrot set, and then plotting the paths of the points that do escape. This process is repeated millions of times, resulting in a highly detailed and intricate fractal image.

This Google Apps Script aggregates data submitted by Google Forms, puts it in .xlsx format and sends it in an HTML formatted email.

This script was written to satisfy a niche case where I temporarily needed a PoS (Point of Sale) to automatically login upon startup using AD credentials.

This Processing sketch loads two images and creates an image mask that blends them together. The transparency of the image mask is determined by 4D Open Simplex Noise, which loops perfectly.

This batch file utilizes robocopy to mirror a list of files contained within "targets.txt" in the same directory.

Here's my take on... Daniel Shiffman's take on... Beesandbomb's take on the cube wave.

In this sketch I turned every pixel of an image into a Lorenz System. I mapped the velocity of that system to the brightness value of the pixel. This was the result. Sadly, the Processing sketch I made this with is gone forever.

This is a virtual simulation of the magnets on my girlfriend's fridge.
