Raspberry Pi: Hands-on with the Pi-Desktop kit

Filed under
Linux

This is the latest in my adventures to see what sort of useful things can be done with a Raspberry Pi. The friendly people at the Pi-Shop.ch recently added the Farnell element 14 Pi Desktop to their offerings. This kit is not only a nice case, it also includes an add-on board which contains a power on/off button (yes!), a Real Time Clock with battery backup, and an mSATA socket so that you can add an SSD (Solid State Disk) if you want.

There is also a software download available from the element 14 Pi Desktop page which adds the necessary functionality to the Raspbian operating system to make the On/Off switch, RTC and SSD work. Note that this software is required for any of these new hardware bits to work; the printed installation document included with the Pi Desktop implies that it is only necessary if you want to boot from SSD or USB, but that is not true.

Cinnamon 4.0 Will Tackle Screen Tearing on Linux Mint

Linux Mint plans to make more performance improvements to the Cinnamon desktop ahead of its next release. Similar work featured as part of Cinnamon 3.8, released as part of Linux Mint 19, and improved the responsiveness of launching apps on the desktop. For the next major release of the Cinnamon desktop environment, the team want to tackle another performance-related bugbear: screen tearing. “On modern NVIDIA GPUs we’re able to get rid of screen tearing by using “Force Composition Pipeline” in NVIDIA-Settings. With Vsync disabled in Cinnamon we then enjoy a faster desktop environments with no screen tearing,“, writes Cinnamon’s lead developer Clement Lefebvre in a recent blog post. Read more

4 open source media conversion tools for the Linux desktop

Ah, so many file formats—especially audio and video ones—can make for fun times if you get a file with an extension you don't recognize, if your media player doesn't play a file in that format, or if you want to use an open format. So, what can a Linux user do? Turn to one of the many open source media conversion tools for the Linux desktop, of course. Let's take a look at four of them. Read more

Launching Open Source Initiatives Is the Next Battleground In Quantum Computing

At a time when tech giants are ploughing millions of dollars in quantum computing and are striving ahead with breakthroughs, Google, Microsoft and IBM seem to be locked in an intense battle of quantum supremacy. Mountain View search giant announced Cirq — an open-source framework for NISQ computers. Cirq is an open-source initiative that allows developers to create algorithms that can run on a number of machines without having a full background in quantum physics. The Google blog notes that once installed — Cirq enables researchers to write quantum algorithms for specific quantum processors. “Cirq gives users fine-tuned control over quantum circuits, specifying gate behaviour using native gates, placing these gates appropriately on the device, and scheduling the timing of these gates within the constraints of the quantum hardware,” the blog notes. Cirq supports running these algorithms locally on a simulator and is designed to easily integrate with future quantum hardware or larger simulators via the cloud. Read more
