This article shows how to use curses functions to read the keyboard and manipulate the screen. My previous article introduced the ncurses library and provided a simple program that demonstrated a few curses functions to put text on the screen. In this follow-up article, I illustrate how to use a few other curses functions.

I recently got my hands on a SparkFun micro:arcade kit and micro:bit single-board computer. It's a great combination of hardware for adults and kids who want to build and program their own arcade console and games.

By design, Linux is a very secure operating system. In fact, after 20 years of usage, I have personally experienced only one instance where a Linux machine was compromised. That instance was a server hit with a rootkit. On the desktop side, I’ve yet to experience an attack of any kind.

Sometimes, while working on a Linux machine, you'll see that an application or a command line process gets stuck (becomes unresponsive). Then in those cases, terminating it is the only way out. Linux command line offers a utility that you can use in these scenarios. It's called kill.

In this week's top 5, we take a look at the top 6 desktop email clients, the cp command, a DeLorean that runs Perl, and more.

Mycroft has Kickstarted an open source “Mycroft Mark II” smart speaker and voice assistant that runs Linux on a quad-core Xilinx SoC, and offers a 6-mic beamforming array, 10W speaker, 4-inch touchscreen, and a promise of user privacy. Mycroft launched its Kickstarter campaign for the original, voice-activated Mycroft home automation hub back in Aug...

The more secure Red Hat Enterprise Linux 7.5 is now out in beta.

Kubernetes is an open source platform that offers deployment, maintenance, and scaling features. It simplifies management of containerized Python applications while providing portability, extensibility, and self-healing capabilities. Whether your Python applications are simple or more complex, Kubernetes lets you efficiently deploy and scale them, seamlessly rolling out new features while limiting resources to only those required. In this article, I will describe the process of deploying a simple Python application to Kubernetes, including: read more

The previous Magazine article on container testing showed how to use Meta-Test-Family (MTF) to validate  standalone containers. The goal is to avoid shipping containers without proper testing, and to guarantee that a given service in a container works properly. Another... Continue Reading →

Grav is a modern web application that requires no database. It's a file-based web platform that's simple and fast. In this tutorial, I will show you step by step how to install and configure Grav CMS on Ubuntu 16.04.

Whistleblowing protections, crowdsourcing, anonymous voting processes, and even Glassdoor reviews—anonymous speech may take many forms in organizations. As well-established and valued as these anonymous feedback mechanisms may be, anonymous speech becomes a paradoxical idea when one considers how to construct a more open organization. While an inability to discern speaker identity seems non-transparent, an opportunity for anonymity may actually help achieve a more inclusive and meritocratic environment. read more

This tutorial shows how to encrypt your files by using Tomb on Ubuntu 16.04. Tomb is an alternative to Truecrypt and Veracrypt designed for Linux systems.

In my previous article for Opensource.com, I introduced the OpenHPC project, which aims to accelerate innovation in high-performance computing (HPC). This article goes a step further by using OpenHPC's capabilities to build a small HPC system. read more

Google's parent company Alphabet has launched a security company named Chronicle. The business will be the new home of VirusTotal, which Google acquired in 2012. Chronicle's other story will be "a new cybersecurity intelligence and analytics platform that we hope can help enterprises better manage and understand their own security-related data."

Technology is continually providing us with new ways to create and publish stories. For these stories to achieve their full impact, it requires that the tools to deploy them become accessible and easy to use. That’s one of the reasons why Mozilla has worked to develop A-Frame, a framework that makes it easy for anyone to build virtual reality experiences for the web.

Adlink’s Linux-ready “IMB-M43H” ATX board supports Skylake or Kaby Lake Intel Core CPUs with up to 32GB DDR4, 4x SATA III, 8x USB, PCIe and PCI, EN 55032 EMI protection, and USB power stabilization. Adlink’s industrial ATX form-factor (305 x 244mm) IMB-M43H is designed as a Skylake or Kaby Lake upgrade for legacy installations.

Fixing the chip security holes Meltdown and Spectre will take a long, long time, but Linus Torvalds and Intel developers are slowly moving to answers for Linux.

What's new in kernel development: complexifying printk(). It's so simple! The kernel decides to output a log message, so it calls printk() to send the message to a serial console—except it's not simple at all. What if the kernel is in the middle of crashing, and the log message is the crucial clue needed to diagnose the problem?
