+OpenEnergyMonitor are using Raspberry Pi as the base station for their #opensource  energy monitoring system, emonPi. It's designed to be easy to set up, yet still hackable and customisable for different types of monitoring application - home energy, solar PV, heat-pump and temperature & humidity. Their Kickstarter campaign has ten days left to run.

Google monetizing LINUX DESKTOP?

In short: Android Apps (with Google appstore behind) now run safely within Chrome browser!

Best: Linux, as basic operating system below, completely stays free and open, giving the user any freedom, very much unlike Microsoft™ architecture, which puts whole OS into prision: No chance to run uncertified touch GUI (aka 'Metro') applications.

Understanding things behind is a bit more complex.

First, Google Chrome or Chromium, like Chrome OS, now generally starts an app in it's own, virtual machine, completely emulating #ARM instruction set, ARM mobile hardware within Linux kernel. That's called 'ARC Welder' now.

Internally, it's called 'goldfish': http://www.strazzere.com/blog/2014/07/compiling-an-emulator-kernel-for-loadable-modules/

'Goldfish' is a complete ARMv7 mobile emulator running as kernel module. In former times #QEMU did emulate an Android mobile for e.g. development purposes.

Chrome / Chromium now was redesigned to display graphical output from that Android VM within a simple browser window.

But not only that: Chrome/Chromium now is able to display graphical output from any VM within a browser window!!! UBUNTU™ now can run in a Chrome browser tab!!!

That all began with a script named "Crouton", that lets you run Ubuntu™ or #Debian on a #Chromebook without uninstalling Chrome OS. Originally developed by David Schneider, that tool has been around for a few years, offering an easy way to run native desktop Linux apps such as GIMP, #LibreOffice, and even Firefox on Chrome OS laptops and desktops.

But up until recently you’ve had to flip back and forth between Chrome OS and Ubuntu desktop environments … now there’s an option to simply run Ubuntu in a browser tab.

Best again: All these apps now run graphics hardware accelerated. For a better understanding you may have a deeper look into, what Google has done for pushing Linux development:

http://dev.chromium.org/developers/design-documents

Means: Chrome / Chromium now can run UBUNTU™ Linux, Android safely in a VM (see #LXC / #Docker ) redirecting graphical output to a browser tab.

Interestingly, that now also works - remote. You just have to put some VNC libraries in between, pushing pixels, receiving mouse, keyboard input via network.

This work is already done, but still rarely advertised. See e.g. LibreOffice remote client for #Android, to be found in Google Android app store.

Have fun!
