Determining the Winding of a Polygon Given as a Set of Ordered Points

When working with spatial data one often needs to work with polygons to demarcate bounding areas. One important concept related to this is winding, which defines the relative order in which the vertex points of a polygon are listed. Winding can be either clockwise (CW) or counter-clockwise (anti-clockwise) (CCW), referring to the direction in which we pass through the vertices... Read more >>

Message Functions

One common functionality for software is the need to provide human readable text messages. This is true of native applications, web applications, and many back-end systems. For applications with a user interface there is often a requirement that these messages be localized, that is, provided to the user in the user’s native language. For this reason, best practices dictate that... Read more >>

Technology Radar 2014

We’re releasing our first Technology Radar. A Technology Radar, pioneered by ThoughtWorks, is a list of the techniques, tools, platforms, languages, and frameworks divided into recommendation levels: Adopt, Trial, Assess and Hold. It’s mostly a list of things we find useful and interesting.

We’ve built our own Technology Radar for several reasons. We think it will be useful internally... Read more >>
