April 2014 Issue of Linux Journal: High Performance Computing

Reuven M. Lerner starts us out this month, this time with information on how to leverage geolocation information in your Web application. Whether you want to give your Web visitors a local weather forecast or just want to present them with location-appropriate options from your Web applications, geolocation is a powerful tool. Since the Internet is global, it's important to know where users are located. Reuven shows how to integrate geolocation awareness into your Web applications. Dave Taylor follows with the next in his series on Zombie Dice. It may feel like you're just making a cool game, but it's really just a ruse to help you learn something. (Well, it's a cool game too, but you really are learning!)

Why Facebook Does SDN

In a Cumulus Networks-sponsored webcast SDN panel on March 21, Najam Ahmad, Facebook's director of technical operations, explained why the social networking website has embraced the open SDN model.

Ahmad said that when it comes to the reasons SDN makes sense for Facebook, it boils down to two key things: scale and agility. He noted that there is a lot of traffic going between machines today that runs over network infrastructure. In order to scale the network to meet the needs for increasing machine-to-machine traffic, the traditional hierarchy-based network structure isn't a good fit.
