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>>

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>>

Puerto Rico Python User Group Celebrates First Anniversary

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>>

Non-Linux FOSS: Persistence of Vision Raytracer (POV-Ray)

Back in the mid-1990s, a college friend (hi Russ!) and I would put our old 8088 computers to work rendering ray-traced images for days—literally. The end result would be, by today's standards, incredibly low resolution and not terribly interesting. Still, the thought of a computer system creating realistic photos from nothing more than math equations was fascinating. more>>

Zedge, for All Your Annoying Ringtones!

I really don't understand folks who use songs as their ringtones. Isn't it annoying or confusing when the song comes on the radio? If it's your favorite song, don't you get desensitized to it when you listen to the CD (or digital equivalent of CD)? Nevertheless, you probably hear dozens of ringtones every day. Those probably vary from "super annoying" to "what a cool ringtone". 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.

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.
