The Kubernetes orchestration platform is such a gigantic open source project that its evolution is inherently rapid. The pace of change significantly increases the importance of adhering to security best practices when using the ever-changing Kubernetes platform to automate deployment, scaling, and management of containerized cloud-native applications. read more

Linus Torvalds bashes CTS Labs' AMD chip report, calling it "more like stock manipulation than a security advisory...

In summer 2017, I wrote two how-to articles about using Ansible. After the first article, I planned to show examples of the copy, systemd, service, apt, yum, virt, and user modules. read more

Red Hat's Spectre remediation currently requires new microcode for a complete fix, which leaves most x86 processors vulnerable as they lack this update. Oracle has released new retpoline kernels which completely remediate Meltdown and Spectre on all compatible CPUs, which I install and test on CentOS here.

"Hello world" is the beginning of everything when it comes to computing and programming. It's the first thing you learn in a new programming language, and it's the way you test something out or check to see if something's working because it's usually the simplest way of testing simple functionality. read more

The Ubuntu-driven LimeSDR Mini SBC has begun shipping to backers, who have spent over $500M on the open source software defined radio hacker board, and it’s now heading to space in a deal with the European Space Agency.

In this tutorial series, we're providing practical guidelines for using PGP. If you missed the previous article, you can catch up with the links below. But, in this article, we'll continue our discussion about securing your keys and look at some tips for moving your subkeys to a specialized hardware device.

The Linux Foundation announced an Intel-backed embedded reference hypervisor project called “ACRN” that features real-time and safety-critical features for Linux and Android IoT and automotive projects. At the Embedded Linux Conference in Portland, Oregon, the Linux Foundation announced a project called ACRN (like “acorn”) based on Intel technology that will develop a lightweight, open source embedded reference hypervisor.

The Raspberry Pi 3 Model B+ has gone on sale for $35, boosting the Model B’s quad -A53 SoC to 1.4GHz, speeding the WiFi to precertified, dual-band 802.11ac, and adding USB-based GbE with PoE support. Two years after the arrival of the Raspberry Pi 3 Model B, which brought wireless and 64-bit ARMv8 computing to […]

Last April, a federal court in California handed down a decision in Artifex Software, Inc. v. Hancom, Inc., 2017 WL 1477373 (N.D. Cal. 2017), adding a new perspective to the forms of remedies available for breach of the General Public License (GPL).

Gaming has traditionally been one of Linux's weak points. That has changed somewhat in recent years thanks to Steam, GOG, and other efforts to bring commercial games to multiple operating systems, but many of those games are not open source. Sure, the games can be played on an open source operating system, but that is not good enough for an open source purist. read more

Since the turn of the millennium, online publishing has turned into a vampire, sucking the blood of readers' personal data to feed the appetites of adtech: tracking-based advertising. Resisting that temptation nearly killed us.

We regularly measure particulate matter in the air at our school in Southeast Asia. The values here are very high, particularly between February and May, when weather conditions are very dry and hot, and many fields burn. These factors negatively affect the quality of the air. In this article, I will show you how to measure particulate matter using a Raspberry Pi. read more

Raspberry Pi just celebrated its sixth birthday—that's six years since the launch of the original Raspberry Pi. Since then, it has released various new models, including the Pi 2, Pi 3, and Pi Zero. So far, 9 million Raspberry Pi 3s have been sold—and over 18 million Pis in total—and those numbers are likely to grow following today's announcement of the Raspberry Pi 3 Model B+. This new Pi features: read more
