For another site of mine I needed a way to determine whether black or white was a better choice for text on a randomly colored background. The function takes a color as an array with elements r, g, and b and returns an array with the same 3 elements. Although in the returned array all… Read more »

Math for Game Programmers
Had an idea running through my head for a while now and finally pulled the trigger last weekend. Something I’ve noticed teaching students to write games is that most don’t expect programming games to involve as much math as it does.

Map of the Japan earthquakes

CompSci Minor and employment
Came across a new blog to add to my reader last week called CompSci Woman. I’m always on the lookout for articles to give my students that show computer science as something other than the Office Space view of a pasty white guy sitting in a cubicle or his parents’ basement, and the first couple… Read more »
TinEye – Finding your images on the web
Came across a new search engine called TinEye last week. It lets you either upload or paste a link to an image and it searches its index looking for the same image. For those that make money off of their images, or just don’t want copies on other sites, this is a good way to… Read more »
