Google announced that its third Code-in contest for high school students will start on November 26. The contest, which aims to introduce 13-17 year old pre-university students to open source software development, will run from November to mid January and the 20 grand prize winners (and one of their parents or legal guardians) will get a trip to Mountain View to explore the Google campus and meet with Google employees. The Code-in program will feature a number of tasks related to existing open source projects, all of which have experience mentoring students through Google’s Summer of Code program for college students.
