RasPi.TV has Kickstartered a $12 “RasPiO Analog Zero” Raspberry Pi add-on board the size of an Raspberry Pi Zero. It offers eight 10-bit analog inputs.
The RasPiO Analog Zero has surpassed its Kickstarter goals, and is available through May 31 starting at 8 Pounds ($12). Designed for reading up to eight analog sensors simultaneously on a Raspberry Pi, the add-on board is matched to the size of the 65 x 30mm Raspberry Pi Zero. However, it plugs into any Pi with a 40-pin expansion connector, and can work with older 26-pin Pi models with the help of an adapter.
It won't be long after starting to use Linux that you ask a question and the answer begins with, "Open a terminal and..." At this point, you may be thrown into an alien environment with typed Linux commands instead of cheery-looking icons. But the terminal is not alien, it's just different.
You are used to a GUI now, but you had to learn that, and the same applies to the command line. This raises an obvious question: "I already know how to use a windowed desktop, why must I learn something different?"
The Raspberry Pi 3 is not hurting for operating system choices. The tiny ARM computer is supported by several Linux distributions and even has a version of Windows 10 IoT core available. Now, it looks like the Pi is about to get official support for one of the most popular operating systems out there: Android. In Google's Android Open Source Project (AOSP) repository, a new device tree recently popped up for the Raspberry Pi 3.
Raspberry Pis, if you're not aware, are cheap, credit card-sized, single board ARM computers with a focus on education and open source software. Hardware hackers and DIYers love the Pi due to its open nature, small size, and plethora of ports and software.
There is a lot of interesting buzz around specialized container hosts, rump kernels, and unikernels because they hold the potential to revolutionize certain workloads (embedded, cloud, etc.). Keep your eye on this exciting, fast moving space, but cautiously.
Currently, unikernels seem quite similar to building printed circuits. They require a lot of upfront investment to utilize and are very specialized, providing benefits for certain workloads. In the meantime containers are quite interesting even for conventional workloads and don't require as much investment. Typically an operations team should be able to port an application to containers, whereas it takes real re-engineering to port an application to unikernels and the industry is still not quite sure what workloads can be ported to unikernels.
Here's to an exciting future of containers, rump kernels, and unikernels!
A few days ago when delivering benchmarks of the new CPUFreq "Schedutil" governor in Linux 4.7 the P-State comparison results on this Git kernel looked particularly terrible. I've since done some P-State tests on the same system using the Linux 4.5 and 4.6 kernels that further point towards a regression having taken place.

Bryce Harrington announced the release today of the release candidates for Wayland 1.11 and the reference Weston 1.11 compositor.
The official 1.11 release candidate announcements can be found via the Wayland-devel mailing list.
Convergence is not a word on everybody's lips. But if Canonical Software, the company that controls Ubuntu, has any say, it soon will be.
Others may be more skeptical.
Canonical describes convergence as "a single software platform that runs across smartphones, tablets, PCs, and TVs. It is designed to help make converged computing a reality: one system, one experience, multiple form factors."
Whom can I recommend CentOS to? Probably to people I mentioned in the very beginning of this article: students who want to dedicate their life to system administration. You need to learn how to search for the answers, how to do things manually. That is your profession. That is your bread. CentOS gives you a brilliant opportunity to learn all of that along with learning the system itself.
But CentOS is not for home users who want things done quickly and easily, I'm afraid.
