This month, our focus is on demonstrating how ODROIDs can be used as personal private cloud servers. Storing files “in the cloud” normally involves subscribing to an expensive third-party service, with the potential for data to be hacked or exposed, as has been demonstrated with recent news articles involving celebrity photos and corporate emails that were released to the public without permission. By installing and configuring software such as Seafile and OwnCloud, you can maintain your preferred level of security by using any ODROID device to host the files at your home or office. By doing so, you can limit exposure to a local secure intranet, so that the chance of an unknown intruder gaining access to them is greatly reduced.

A hot topic in world of cloud computing is Docker, which allows applications to be built on a platform of the developer’s choice, then installed and run on nearly any architecture, including ODROIDs! As demonstrated in the latest Google I/O conference, Docker offers a highly stable environment in which to distribute and compartmentalize applications for scalability purposes. It enables apps to be quickly assembled from various components that are completely portable. Fred Meyer, a Docker expert who recently joined the ODROID Magazine team, presents the first part of an interesting series on getting Docker running on an ARM device.

Now that the ODROID-C1 has been available for a while, the ODROID forum has grown to nearly 8,000 members, with many suggestions, tips, and tutorials being posted daily. Tobias recently uploaded many of his game packages and useful software to the Hardkernel community server, and also put together a guide for connecting to his repository in order to get kernel updates via a simple apt-get command, which is a more convenient way to update custom ODROID software from Debian and Ubuntu.

As always, we bring you reviews of some fun games to play, including several Android programs, as well as a comparison of the gaming power of the ODROID-XU3 vs the ODROID-U3. Nanik continues his excellent series on Android Development with an introduction to the Zygote app, and we feature a tutorial on using your ODROID as a modern digital radio using the GNU radio package.
