RancherOS is a container-native operating system designed solely for running Docker containers. It’s one of 6 operating systems designed just for Docker and other container runtimes in active development.
On an operating system of that nature, you need containers for providing system-wide services other than running applications. They are called system containers in Project Atomic, a container-native OS developed by the folks at Fedora. In this linked-to blogged post, Ivan Mikushin from Rancher, the company developing RancherOS, shows how to use Docker Compose to create such system containers.
At CoreOS, running containers securely is a number one priority. We recently landed a number of features that are helping make CoreOS Linux a trusted and even more secure place to run containers.
As of the 808.0.0 release, CoreOS Linux is tightly integrated with SELinux to enforce fine-grained permissions for applications. Building on top of these permissions, our container runtime, rkt, has gained support for SVirt in addition to a default SELinux policy.
My first Firefox OS device was the Geeksphone Revolution. Hardware wise it was a quite nice device, but the size just didn’t fit my hand and so I droped it a few times until the display was broken.
At that time - beginning of 2015 - I rather tended to go with anohther Firefox OS phone. Luckily the Alcatel One Touch Fire E got introduced at that time and I went with it (paying around € 120,-).

Chip blueprint scribbler ARM has released some of the source code for its first public beta of mbed, its operating system for the Internet of Things.
The Internet of Things is today's fancy word for embedded engineering, and ARM is all over that latter space: the tiny and relatively simple processor cores it designs are used in countless gadgets and gizmos, phones and tablets, controllers and sensors, smartcards, and so on.
