In 2013 I built a Weather App for St. Patrick’s Mental Health Services and their presence at the Ploughing Championships. The App is a classic API mash up using a public Weather API mixed with Google Maps API. The result is an intuitive Weather App that works equally well on desktop or mobile all from a single HMTL deck with Javascript jQuery JSON API calls and CSS3.
Another small hack. Every 15 minutes a script builds a GIF89a image of the Met radar creating an animated sequence of images over time to track the radar. This is achieved with a CRON of some SHELL SCRIPTS I wrote that deploy the Gifsicle Unix application that builds a GIF file from a set of given images.
