LaTeX (pronounced lay-tech) is a method of creating documents using plain text, stylized using markup tags, similar to HTML/CSS or Markdown. LaTeX is most commonly used to create documents for academia, such as academic journals. In LaTeX, the author doesn't stylize the document directly, like in a word processor such as Microsoft Word, LibreOffice Writer, or Apple Pages; instead they write code in plain text that must be compiled to produce a PDF document. read more

Powerful programs run daily by users of Linux and other flavors of Unix are riddled with holes that can be exploited by logged-in miscreants to gain root privileges, researchers at Qualys have warned.

The VIA Mobile360 Surround View Sample Kit, which runs Android on an octa-core SoC, provides real-time 360° vehicle monitoring, recording, and tracking. VIA Technologies has unveiled an embedded computer kit for commercial vehicles that integrates inputs from 4x automotive-grade Sharp FOV-190 or FOV-50 cameras.

One of the most common reasons people give for not contributing (or not contributing more) to open source is a lack of time. I get it; life is challenging, and there are so many priorities vying for your limited attention. So how can you find the time in your busy life to contribute to the open source projects you care about? read more

Monitoring IT infrastructure is essential to ensure its stability. Choosing an efficient, scalable, customizable, and light-weight solution for this has always been a challenge with changing requirements. Custom scripts can be used to achieve this smartly unlike the agent-based monitoring method in which all data defaulted by the monitoring tool used will be collected. This article describes the custom script method for monitoring system resources. In this method, the data collector(s) scripts running on data collector node will poll the target systems for data and so can decide on what data to be pulled.

Linus Torvalds took to the stage in China for the first time Monday at LinuxCon + ContainerCon + CloudOpen China in Beijing. In front of a crowd of nearly 2,000, Torvalds spoke with VMware Head of Open Source Dirk Hohndel in one of their famous “fireside chats” about what motivates and surprises him and how aspiring open source developers can get started. Here are some highlights of their talk. What’s surprising about Linux development

In Linux, there's a command line tool that you can use to create/verify checksum. It's dubbed cksum. Most vendors offer a checksum (or a checksum-like code) corresponding to the file(s) being downloaded. If the file doesn't behave in an expected way, user's can recompute the file's checksum and compare it with the original checksum provided by the vendor to see if the file is intact or got corrupted.

When last we met, we reviewed essential TCP/IP basics for Linux admins in Practical Networking for Linux Admins: TCP/IP. Here, we will review network and host addressing and find out whatever happened to IPv6?

In articles I have written about various aspects of Linux filesystems for Opensource.com, including An introduction to Linux's EXT4 filesystem; Managing devices in Linux; An introduction to Linux filesystems; and A Linux user's guide to Logical Vol read more

The Ztorg malware hid in apps on Google's Play Store to send premium-rate SMS texts and delete incoming SMS messages on Android devices.

Sometimes, while working on the command line, you arrive at a point where there's too much text on the terminal screen, and none of that is relevant to you. So, in order to avoid distraction, you'd want to clear the terminal screen. Those new to the Linux command line may not know that there exists a dedicated command line utility that does this work for you.

Red Hat and community developers took their own sweet time, but the next version of Fedora is finally on the runway and ready to fly.

Robert Kaye is definitely a brainz-over-brawn kinda guy. As the creator of MusicBrainz, ListenBrain and AcousticBrainz, all created and maintained under the MetaBrainz Foundation, he has pushed Free Software music cataloguing-tagging-classifying to the point it has more or less obliterated all the proprietary options.

In the history of computer games, very few are as influential as Colossal Cave Adventure. Initially developed in 1976 by Will Crowther and expanded by Don Woods in 1977, Adventure was the first interactive fiction game and inspired countless other computer games. Adventure directly or indirectly led to the entire corpus of text-based adventure games, and by extension, graphical adventure games. read more

Thecorpora’s Scratch-ready “Q.bo One” robot is based on the RPi 3 and Arduino, and offers stereo cams, mics, a speaker, and visual and language recognition. In 2010, robotics developer Francisco Paz and his Barcelona-based Thecorpora startup introduced the first Qbo “Cue-be-oh” robot as an open source proof-of-concept and research project for exploring AI capabilities in […]

Kdump is a way to acquire a crashed Linux kernel dump, but finding documents that explain its usage and internals can be challenging. In this article, I'll examine the basics of kdump usage and look at the internals of kdump/kexec kernel implementation. read more

For many Linux systems engineers, Ansible has become a way of life. They use Ansible to orchestrate complex deployment processes, to define multiple systems with a quick and simple configuration management tool, or somewhere in between. However, Microsoft Windows users have generally required a... Continue Reading →
