In this tutorial, we will discuss the vector algebra and corresponding calculations under Scientific Linux. For our purpose, I have chosen Python as the programming language for its simplicity and power of calculation. Any Linux distribution has by default a Python editor / compiler which is invoked through a terminal window. Let's go over some concepts of vector algebra.

On the final day of LinuxCon North America 2015, Linux Foundation Executive Director Jim Zemlin welcomed a "surprise" guest, Linus Torvalds, to the stage for a brief Q&A session. Zemlin read quotes from a recent article about Torvalds, The creator of Linux on the future without him, which said, "Torvalds may be the most influential individual economic force of the past 20 years." Torvalds jokingly responded, "I love open source and how all the credit goes to me," but then he explained that the power he has over the Linux kernel is just the power to say no—he doesn't actually write the code anymore. read more

Below is a video of that appearance—on Wednesday, June 24, 2015—along with a transcript of the conversation for the first six and a half minutes. This is a transcription. read more

Computer science courses at universities are great at teaching algorithms, basic principles, and the theoretical foundation of computing. While these are essential for broader grasp of the discipline, graduates often find themselves lacking the practical skills needed by companies in their day-to-day operations. read more

We know, on the internet today, that attackers have the advantage," Schneier said. "A sufficiently funded, skilled, motivated adversary will get in. And we have to figure out how to deal with that." Using the example of last November's crippling online attack against Sony Pictures, Schneier said it was clear that many of these new attacks were the work of well-funded nation-states.

Like it or not, email isn't dead yet. And for Linux power users who live and die by the command line, leaving the shell to use a traditional desktop or web based email client just doesn't cut it. After all, if there's one thing that the command line excels at, it's letting you process files, and especially text, with uninterrupted efficiency. read more

Axiomtek’s “MANO842″ Mini-ITX board runs Linux on a quad-core Bay Trail Celeron, and offers PCIe, mini-PCIe, SATA, and a choice of ATX 12V or 12V DC power. The MANO842 is the latest of Axiomtek’s MANO-branded Mini-ITX boards, such as its Intel 4th Gen Core based MANO881. The new MANO842 opts for the Bay Trail generation […]

In a broad-ranging question and answer session, Linus Torvalds, Linux's founder, shared his thoughts on the current state of open source and Linux.

In 2015, the Free Software Foundation presented Reglue the Award for Projects of Social Benefit. After losing his larynx to cancer, Ken used text-to-speech (TTS) software to present at LibrePlanet 2015. In this interview, Ken tells us about his Texas Linux Fest talk, Text-to-speech and Linux.

Just wants to get through next 6 months. LinuxCon 2015 Linux kernel maintainer Linus Torvalds isn't thinking about where his creation will be ten years from now – in fact, he claims he doesn't even think ahead one year.

In a broad-ranging question and answer session, Linus Torvalds, Linux's founder, shared his thoughts on the current state of open source and Linux.

Dolphin's new look - based on KDE Frameworks 5. Today KDE released KDE Applications 15.08, the collection of more than 150 applications. This release features the Kontact Suite and Dolphin ported to KDE Frameworks 5.

One of the things that makes Python so powerful is that you can find a module for almost anything. In this article, I cover Astropy, which was originally developed by the Space Telescope Science Institute for doing astronomy calculations like image processing and observatory calculations.

The Linux Foundation's Core Infrastructure Initiative is reaching out to the community to help determine which open-source projects practice good security methods.

The second day of LinuxCon in Seattle started with an announcement by Linux Foundation Executive Director Jim Zemlin about the Core Infrastructure Initiative. The CII will have a new free badge program. According to the program site, "Projects having a CII badge will showcase the project's commitment to security." The first draft of the badge criteria is available on GitHub, and community feedback is encouraged. read more

Google Drive is a popular online service that allows for the easy sharing and collaborative editing of documents (word files or spreadsheets). Under the most usual day to day circumstances, the GDrive tool is very useful serving as a cloud space and/or a readily available online collaboration platform. On this guide, we will see how you can install an open source client tool for the service named Grive, and how to set it up according to your needs.

ADI will announce an enhanced, open-source “MinnowBoard Turbot” SBC at IDF on Aug. 19, featuring a higher performance CPU, regulatory compliance, and more. While crawling the expo at the Intel Developer Forum held in San Francisco this week, we were treated to a sneak preview of a new “MinnowBoard Turbot” single-board computer at ADI Engineering’s […]
