Until now to make my source code pretty I’ve used a pretty dodgy method that involved going from Visual Studio to Word to Blogger and surrounding the lot in a div to apply some styles to the whole thing.

It is sometimes necessary to group the rows of a HTML table. Say you want to display tabular data of a person and their qualifications, you could achieve this by having the name of the person and qualification on separate rows.

Game development introduced me to programming when I was around 10 years old, and I’ve loved it ever since. One of the first formal algorithms I learned before entering university was A* (pronounced “A star”), and I really had a great time learning about it. It’s one of the most widely used pathfinding algorithms and is one that you would likely be introduced to first when approaching the subject of pathfinding. A pathfinding algorithm takes a start point (also known as a node) and a goal and attempts to make the shortest path between the two given possible obstacles blocking the way.

This article goes over the capabilities and syntax of arrays in JavaScript.

I always assumed JavaScript had the ability to create custom objects but only bothered learning how to do so recently. Turns out it’s incredibly easy to create custom “objects” with parameters.

I’m always surprised at how many people I’ve worked with that don’t know how to do this. To center a block vertically and horizontally apply the following CSS.

The singleton design pattern enables easy access to a single instance of a class.

That latter point is incredibly important, if the icons are badly chosen then it just introduces confusion for the user.
