Open source smart thermostats



What Google can really do with Nest, or really, Nest’s data



Open source smart thermostats rise to compete with Nest after Google acquisition | Ars Technica:

 "open source version of a smart thermostat using their own Spark Core, an Arduino-compatible Wi-Fi development board. They added in a humidity and temperature sensor, IR motion detector, and some LEDs and LED matrices to put together and mount inside a custom wood and acrylic enclosure."



 

In all, the team completed its open source version in less than 20 hours for “about $70,” including their $39 Spark Core. The thermostat is still in the experimental stage and lacks much of the sophistication and “smartness" of the Nest, but it still constitutes a networked and remotely controllable thermostat that has a memory of its own work.

LXC - Linux Containers

LXC - Linux Containers:
"LXC is a userspace interface for the Linux kernel containment features.
Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers."

LXC - Wikipedia, the free encyclopedia
LXC provides operating system-level virtualization not via a virtual machine, but rather provides a virtual environment that has its own process and network space. LXC relies on the Linux kernel cgroups functionality that was released in version 2.6.24. It also relies on other kinds of namespace-isolation functionality, which were developed and integrated into the mainline Linux kernel. 

LXC is similar to other OS-level virtualization technologies on Linux such as OpenVZ and Linux-VServer, as well as those on other operating systems such as FreeBSD jails, AIX Workload Partitions and Solaris Containers.
