DNSSEC Part I: the Concepts

Like IPv6, DNSSEC is one of those great forward-looking protocols that unfortunately hasn't seen wide adoption yet. Before I implemented it myself, I could see why. Although some people think BIND itself is difficult to set up, DNSSEC adds an extra layer of keys, key management and a slew of additional DNS records. more>>

Imagine what Puerto Rico would be like, if free software could become a movement for social justice on the island. Well, on Tuesday, February 11th, 2014, the Institute for a Free Puerto Rico planted the seed for this movement. more>>

Okay, Google

My favorite scene in Star Trek IV is when Scotty tries to use the computer in the 1980s. When he's told he must use the mouse, he responds, "how quaint", and then proceeds to try speaking into the mouse for the computer to respond. more>>

It's about the User: Applying Usability in Open-Source Software

Open-source software developers have created an array of amazing programs that provide a great working environment with rich functionality. At work and at home, I routinely run Linux on my desktop, using Firefox and LibreOffice for most of my daily tasks. I prefer to run open-source software tools, and I think most Linux Journal readers do too. more>>

Full SteamOS Ahead!

Although its timetable may not always be ideal, Valve has come through for Linux users lately. Not only has it released a native Linux version of Steam (with many native games!), it also has expanded its Linux support as the basis for its standalone SteamBox. The first step toward a Steam-powered console is the operating system. more>>

Free IBM Cloud Platform for developers…yeah, that’s a big deal. That platform being based on the latest IBM POWER7 and POWER7+ processor-based servers running Linux, AIX and IBM i operating systems…very big deal indeed! more>>

Linux Help for Neuroscientists

In past articles, I have looked at distributions that were built with some scientific discipline in mind. In this article, I take a look at yet another one. In this case, I cover what is provided by NeuroDebian. more>>

A Look at Warzone 2100

I'm not really much of a computer gamer. That said, I'm both ashamed and oddly proud of the hours (probably thousands!) I spent playing Dune 2000 back when it was cutting-edge gaming technology. There's just something about real-time strategy games that appeals to those of us lacking the reflexes for the more action-packed first-person shooters. more>>

Geek's Guide to Valentine's Day Gifting

Valentine's Day is right around the corner, but there is still time to find something awesome for the geeks in your life.

Anubis, the God of Dead Bitcoin Miners

With the recent resurgence of Bitcoin and the subsequent vitality of other cryptocurrencies (Litecoin, for instance), I've been receiving lots of e-mail messages asking how to mine. I've discussed cryptocurrencies in LJ quite a bit during the past few years. Recently, a friend introduced me to Anubis, so I want to mention it briefly here. more>>

On February 20, 2014 we will celebrate our first anniversary with an open format meeting with lightning talks from the community. more>>

Girls and Software

December 2013's EOF, titled "Mars Needs Women", visited an interesting fact: that the male/female ratio among Linux Journal readers, and Linux kernel developers, is so lopsided (male high, female low) that graphing it would produce a near-vertical line. more>>

February 2014 Issue of Linux Journal: Web Development

Spiders are really cool. Granted, they're terrifying, but they're still really cool. more>>

Rails and PostgreSQL

Regular readers of this column won't be surprised to hear that I love both Ruby on Rails and PostgreSQL. Rails has been my primary server-side Web development framework for about eight years, and it has managed to provide solutions for a large number of consulting and personal projects. more>>

Stream and Share Your Media with PlexWeb

Plex is one of those applications I tend to write about a lot. It's not because I get any sort of kickback or even a discount, but rather it's just an incredible system that keeps getting better. more>>

Make Peace with pax

pax is one of the lesser known utilities in a typical Linux installation. That's too bad, because pax has a very good feature set, and its command-line options are easy to understand and remember. pax is an archiver, like tar(1), but it's also a better version of cp(1) in some ways, not least because you can use pax with SSH to copy sets of files over a network. more>>

Two Pi R 2: Web Servers

In my last article, I talked about how even though an individual Raspberry Pi is not that redundant, two Pis are. I described how to set up two Raspberry Pis as a fault-tolerant file server using the GlusterFS clustered filesystem. more>>

SIDUS—the Solution for Extreme Deduplication of an Operating System

SIDUS (Single-Instance Distributing Universal System) was developed at Centre Blaise Pascal (Ecole normale supérieure de Lyon, Lyon, France), where one administrator alone is in charge of 180 stations. Emmanuel Quemener started SIDUS in February 2010, and he significantly cut his workload for administering this park of stations. SIDUS is now in use at the supercomputing centre PSM more>>

Linux Graphics News

Last October, our last look at graphics focused on the plans laid at September's X Developer's Conference. In the three months since then, these plans have come to fruition, reasserting the continuing relevance of X.org compared with Wayland and other compositing display servers. more>>

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority.

Webinar
Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
