+Google Android Is Open Source: LinuxCon
+=======================================
+
+**Google's top-open source exec explains at the  LinuxCon conference why Android is open source and why open source is a key part of Android's success.**
+
+NEW ORLEANS—Google Director of Open Source Chris DiBona took the keynote stage at the LinuxCon conference here on Sept. 16 with a key message: Android is open source.
+
+DiBona plays a key role at Google in helping to make sure that his company does right by the open-source community and is compliant with open-source licensing requirements. During his keynote, DiBona explained that from the very beginning of Android's strategic development back in 2005, a core underpinning of the platform has been about being open.
+
+The challenge for Google in 2005 was that it was difficult to get its search engine onto phones. At the time, the handset market was a closed system and Google had to go through a carrier-by-carrier process to get on phones. Android in part was an effort by Google simply to make sure that its search engine could be easily deployed on any phone.
+
+"We wanted people to have the same experience on their phone as they did on the desktop, but no options were available in open source," DiBona said.
+
+With Android, Google wanted to provide a new minimum level of capabilities that users should expect from a phone, DiBona said. What Google didn't want was to have to continuously cut deals with carriers in order for Google search—or, for that matter, any given Website—to run on any phone.
+
+"Cell phone operators can't compete by restrictions anymore; there has to be a level of freedom," DiBona said.
+
+Android has been a tremendously successful effort for Google that gets better every year, according to DiBona. Currently, 1.3 million Android devices are activated daily, he noted.
+
+###Linux
+
+While Android leverages Linux as part of its platform, Android has had some issues with Linux in the past. In 2010, the Google Android code [was dropped][1] from the mainline Linux kernel.
+
+It was not until March of 2012 with the [Linux 3.3 kernel][2] release that Android finally returned to the mainline Linux kernel. DiBona commented that he always thought that it was a good idea for Linux and Android to be together. The dispute was a deeply technical one and dealt with [wake locks][3], a power-saving mechanism.
+
+Linux dispute aside, DiBona said that while some have questioned whether or not Android really is open source, there is a surefire way to prove that it is. Android can be shipped by anyone and included in any product, without Google's involvement or even permission. That fact is enabled by the permissive open-source license under which Google makes Android available.
+
+In the final analysis, DiBona stressed that open source is what makes Android work for Google, and it's a powerful concept that is at the core of Android.

+Red Hat Expands Virtualization Options With Open-Source Docker
+==============================================================
+

+
+**Red Hat teams up with the developers behind the open-source Docker container technology to provide an alternative to virtualization hypervisors.**
+
+Linux vendor Red Hat is working with virtualization vendor dotCloud to bring a new type of open-source container technology, called "[Docker][1]," to the Fedora community Linux project. Fedora is a Linux project that is sponsored by Red Hat.
+
+Virtualization technology on Linux today typically includes hypervisors such as KVM and Xen as well as container technology in the form of the [Linux LXC][2] project (LinuX Containers). Fedora Project Leader Robyn Bergeron explained to eWEEK that Red Hat has been using container technology as part of its OpenShift platform-as-a-service (PaaS) solution to provide application isolation.
+
+Docker is not the container technology that Red Hat is currently using for OpenShift, though Bergeron noted Docker does have a similar type of container approach. Bergeron said both dotCloud, the lead commercial vendor behind Docker, and Red Hat had been receiving requests about having Docker work on Red Hat-based Linux systems. The partnership between dotCloud and Red Hat will see Docker packaged for Fedora Linux as part of a collaborative open-source development.
+
+Solomon Hykes, founder of dotCloud and the creator of the Docker project, explained to eWEEK that Docker is not a replacement for LXC containers.
+
+"Docker uses LXC under the hood, combined with other technologies," Hykes said. "It's a collection of low-level technologies that already existed, but organized in a way that is more than the sum of its parts."
+
+The goal is to bring to the world of [DevOps][3] a unit of technology that both developers and operations people can understand and use, according to Hykes. A Docker container contains all the binary, library and configuration files necessary to run a particular process.
+
+"We're orienting the use of containers toward the deployment of applications, as opposed to just treating them like miniature servers," he said.
+
+###Containers vs. Virtual Machine Hypervisors
+
+In the enterprise server space, many system administrators today are familiar with virtualization hypervisors such as VMware ESX, Xen and KVM. Hykes sees container technology as being complementary to hypervisors.
+
+"What has happened with hypervisors is that it's a great technology, but the industry sees it as a big hammer and is trying to use it everywhere," he said.
+Hykes sees virtual machine (VM) hypervisors as a server type that provides an alternative to a bare metal machine. In contrast, the job of the container is to deliver a unit of software.
+
+###Red Hat and Docker
+
+As part of the development partnership with Red Hat, Hykes said his first goal is to make sure that the usage of Docker on Red Hat-based Linux systems is a smooth one. He admitted that the current Docker 0.6 version doesn't run properly on Red Hat-based Linux systems, including the Fedora Linux system. The goal with the 0.7 release will be to change that and make Red Hat-based Linux systems a first-class citizen for Docker deployments.
+
+To date, dotCloud has raised $10 million in venture funding for its Docker development efforts. Hykes noted that there is not yet a commercial product, as his first priority is to build the Docker community and user base.
+
+"Phase one for us at dotCloud is to make sure Docker is ubiquitous and that larger players in IT are comfortable with it," Hykes said. "Having Red Hat working with us is a huge win."
