Scrambling Eggs for Spotify with Knuth's Fibonacci Hashing
In this blog post, we explore Spotify's journey from using the Fisher-Yates shuffle to a more sophisticated song shuffling algorithm that prevents clustering of tracks by the same artist. We then connect this challenge to Fibonacci hashing, and propose a novel, evenly distributed artist shuffling method.

π in Other Universes
Everyone loves $\pi$. It’s usually the first irrational number someone encounters. $\pi$ is conceptually simple enough that it can be explained with basic geometry.

"I don't know the numbers": a math puzzle
I saw a math puzzle the other day on Hacker News. It reads as follows:
Two numbers are chosen randomly, both are positive integers smaller than 100. Sandy is told the sum of the numbers, while Peter is told the product of the numbers.
Then, this dialog occurs between Sandy and Peter:
Peter: I don’t know the numbers. Sandy: I don’t know the numbers. Peter: I don’t know the numbers.

VisuAlgo was conceptualised in 2011 by Associate Professor Steven Halim (NUS School of Computing) as a tool to help his students better understand data structures and algorithms, by allowing them to learn the basics on their own and at their own pace. Together with his students from the National University of Singapore, a series of visualizations were developed and consolidated, from simple sorting algorithms to complex graph data structures. Though specifically designed for the use of NUS students taking various data structure and algorithm classes (CS1010/equivalent, CS2040/equivalent (inclusive of IT5003)), CS3230, CS3233, and CS4234), as advocators of online learning, we hope that curious minds around the world will find these visualizations useful as well.

Teaching Mathematics – Graph Theory | Math ∩ Programming
Community Service Mathematics is supposed to be a process of discovery. Definitions, propositions, and methods of proof don’t come from nowhere, although after the fact (when presented in a textbook) they often seem to. As opposed to a textbook, real maths is highly non-linear. It took mathematicians quite a lot of fuss to come up with the quadratic formula, and even simple geometric conjectures were for the longest time the subject of hot debate.
