If you have little experience with ARIA, screen readers, or testing in general, understanding accessible descriptions can be trickier than understanding accessible names (already confusing for many). I have written explanations so many times for clients and in fora that I opted to put this together so I maybe never…
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.
Keyboard interaction note for just one control from the entire panoply of HTML controls: A native fires on key down when that key is Enter. If you hold down the Enter key, it continues to fire for as long you hold Enter (or something crashes). A native fires…

Ember Octane has landed along with a large number of new features, but none of these features is more exciting to me personally than autotracking. 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 😄
