Signpost article on {{Calculator}}

 The most recent issue of the Wikipedia Signpost published an article I wrote about the {{calculator}} series of templates, which I worked on.

 The signpost is Wikipedia's internal newspaper. I read it all the time. Its really cool to have contributed something to it. 

So what's this all about?

Essentially I was hired by Wiki Project Med, to make a script to add medical calculators to their wiki, MDWiki.  For example, you might have a calculator to calculate BMI, where the reader enters their weight and height. After being used on MDWiki, the script made its way to Wikipedia.

 The goal of this was to make something user programmable, so that users could solve their own problems without having to wait on developers. The model we settled on was a spreadsheet-esque one. You can define cells that readers can write in, and you can define other cells that update based on some formula.

Later we also allowed manipulating CSS, to provide more interactivity. This opened up a surprising number of opportunities, such as interactive diagrams and demonstrations.
