O'Reilly Releases "Understanding the Linux Kernel, Third Edition"

Filed under
Reviews

The book is not specifically for system administrators or programmers, but for anyone who wants to understand how things really work inside the machine. "It explains the theoretical underpinnings for why Linux, and many other operating systems, do things the way they do," Cesati explains. "We try to go beyond superficial features and offer a background, such as the history of major features and why they were used."

"Understanding the Linux Kernel" differs from other books on Linux internals by discussing the kernel in relation to a specific hardware platform. "Efficient kernels take advantage of most available hardware features, such as addressing techniques, caches, processor exceptions, special instructions, processor control registers, and so on," Bovet points out. "If we want to convince readers that the kernel indeed does quite a good job in performing a specific task, we must first tell what kind of support comes from the hardware."

How to set up Raspberry Pi, the little computer you can cook into DIY tech projects

You don't need an electrical engineering degree to build a robot army. With the $35 Raspberry Pi B+, you can create robots and connected devices on the cheap, with little more than an Internet connection and a bunch of spare time. The Raspberry Pi is a computer about the size of a credit card. The darling of the do-it-yourself electronics crowd, the Pi was originally designed to teach kids computer and programming skills without the need for expensive computer labs. People have used Raspberry Pis for everything from robots to cheap home media centers. The Pi sports USB ports, HDMI video, and a host of other peripherals.

LibreOffice Ported To 64-bit ARM (AArch64)

As more and more open-source programs get brought up for 64-bit ARM, LibreOffice is the latest to receive such AArch64 enablement. As of today in LibreOffice Git is the initial AArch64 support. Over one thousand new lines of code were added to LibreOffice by Red Hat's Stephan Bergmann for allowing the open-source office suite to build on the ARMv8 64-bit architecture. LibreOffice already runs on many CPU architectures from x86 to Alpha and SPARC with ARM64 just being the latest. Read more

SUSE's Flavio Castelli on Docker's Rise Among Linux Distros

Docker has only gained traction since its launch a little over a year ago as more companies join the community's efforts on a regular basis. On July 30, the first official Docker build for openSUSE was released, making this distribution the latest among many to join the fray. I connected with Flavio Castelli, a senior software engineer at SUSE, who works extensively on SUSE Linux Enterprise and has played a major role in bringing official Docker support to openSUSE. In this interview, he discuses the importance of bringing Docker to each Linux distribution, the future of Docker on SUSE Linux Enterprise, and other interesting developments in the Docker ecosystem.
