Millions of students are learning computer code this week as part of "Hour of Code," a nationwide campaign kicked off by President Obama this past Monday. And among them are hundreds of students at The University of Alabama in Huntsville (UAH), whose own site, Hour of Code with UAH 2013, invites Chargers to join the effort. How does it work? By visiting the Hour of Code website, students can learn the basics of computer program through interactive tutorials like "Write your first computer program" and "Introduction to Java Script." They can also participate in person at special sessions held by Apple and Microsoft at their retail stores.
