visualising data structures and algorithms through animation - VisuAlgo
VisuAlgo was conceptualised in 2011 by Dr Steven Halim 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, CS3230, CS3233, and CS4234), as advocators of online learning, we hope that curious minds around the world will find these visualizations useful as well.

Autotracking is Ember's new reactivity system, which is what allows Ember to know when stateful values (such as @tracked properties) have changed. This was a
For years, a trend in our industry has been to build single-page apps, or SPAs.
Today, I want to explore why that’s nonsense. Let’s dig in!
Reactivity, or “reactive programming”, is one of those buzz words that has been thrown around a lot in the past decade or so. It has been applied to many different contexts, and is a very broad concept, so it can be hard to try to distill down exactly what it means. But, I’m going to try 😄
