In Linux, there may be times when you might want to change the owner and group-related information for a file or directory. If you are a command line newbie, and want to know how you can make such changes through the command line, you'll be glad to know that there exists a command - dubbed chown - that lets you do this.

GNOME, the Fedora Workstation default environment, has a well known Alt+Tab feature to switch apps. This control groups windows for a single app together. For example, multiple terminal windows appear as a single terminal app. The Alt+` (backtick or backquote) shortcut switches between those... Continue Reading →

Links are a very handy way to create a shortcut to an original directory. Links are used in many instances: Sometimes to create a convenient path to a directory buried deep within the file hierarchy; other uses for links include:

Oracle wants to be a cloud power, but instead of branding their own cloud DevOps program, they'll be working with CoreOS on Kubernetes.

The Semantic Web, a term coined by World Wide Web (WWW) inventor Sir Tim Berners-Lee, refers to the concept that all the information in all the websites on the internet should be able to interoperate and communicate. That vision, of a web of knowledge that supplies information to anyone who wants it, is continuing to emerge and grow. read more

JavaScript is the lingua franca of the Internet. Like English, it's a language that language snobs love to hate, and it's spoken everywhere. As Anders Hejlsberg said: "JavaScript is the only true cross-platform game in town." read more

Some genuinely exciting news piqued my interest at this year’s DockerCon, that being the new operating system (OS) LinuxKit, which was announced and is immediately on offer from the undisputed heavyweight container company, Docker. The container giant has announced a flexible, extensible operating system where system services run inside containers for portability. You might be surprised to hear that even includes the Docker runtime daemon itself.

NutsBoard.org’s upcoming 3.5-inch, i.MX6-based “Pistachio” SBC follows the recently released TI AM3352 based “Almond” COM, Walnut carrier, and mini-PC. Shortly after Taiwan-based startup NutsBoard.org shipped a TI Sitara AM3352 based, 68 x 38mm Almond computer-on-module, the company went to Computex last week to show off an upcoming Pistachio SBC built around the NXP i.MX6.

Keeping time in Linux is not simple, and virtualization adds additional challenges and opportunities. In this article, I'll review KVM, Xen, and Hyper-V related time-keeping techniques and the corresponding parts of the Linux kernel. Timekeeping is the process or activity of recording how long something takes. We need "instruments" to measure time. The Linux kernel has several abstractions to represent such devices: read more

Protection of system firmware against malicious attack is paramount to server security. If an attacker is able to inject malicious code at the firmware level, no security measure at the operating system level can fully guarantee the trust of the system. IBM OpenPOWER servers support secure boot of system firmware to ensure the system boots only authorized firmware. When the system boots, each firmware component is verified against a cryptographic signature and integrity-checked against a secure hash of the component. If any check fails, secure boot prevents the system from booting until the problem is corrected.

The open source arena continues to rapidly converge with the field of artificial intelligence (AI). Not only are technology industry titans contributing meaningful tools to the community, but international players and billionaires are making contributions. Meanwhile, some of our smartest people are also laser-focused on keeping AI development open and safe.

If being open is so great, why isn't everyone embracing it? Answering this requires asking a few more questions: Why is it so hard for leaders and organizations to introduce and maintain policies and processes designed to create open environments? Why are technology firms and millennial-driven startups more likely to see the value in open strategies? Most leaders in large organizations are more than capable of running successful open systems—so why aren't they doing it? read more

TI’s Linux-driven, Cortex-A8 “Sitara AMIC110” SoC with PRU-ICSS is designed for multiprotocol industrial Ethernet and fieldbus communications. Texas Instruments has announced the AMIC110, the first in a series of Sitara AMIC SoCs designed to “help developers convert existing non-networked designs such as motor drives to networked systems by adding industrial Ethernet.” The SoC’s single-core, 300MHz […]

Over the past few years, Software Defined Networking (SDN) has been a key buzz in the computer networking/IT industry. Today, more and more companies are discussing SDN to leverage it for their business and future growth plans.

It is not often that most of us need to update the BIOS in our host computers. In fact, most motherboard manufacturers, including Intel, recommend against upgrading BIOS unless there is a specific problem that an upgrade to a specific BIOS level will fix. Most sysadmins also would agree that "if it is not broken, don't fix it." Upgrading BIOS just to get to the latest level is counter-productive in terms of the time it takes, but also can cause problems that did not previously exist. read more

After our group of friends founded a small open hardware community in El Salvador a few years ago, we felt alone in the region. The open hardware movement had developed in a creative explosion of projects and (thanks to the popularization of 3D printing and digital technologies such as Arduino) under a common understanding of how to develop new physical products. read more
