Linux Journal - Wed, 2014-02-26 15:20

It's been months, and I'm still dealing with a DDOS (distributed denial of service) attack on my server—an attack that I can see is coming from China, but there's not really much I can do about it other than try to tweak firewall settings and so on. more>>

DNSSEC Part I: the Concepts

Linux Journal - Mon, 2014-02-24 12:42

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

Linux Journal - Wed, 2014-02-19 13:41

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

Linux Journal - Tue, 2014-02-18 13:34

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!

Linux Journal - Thu, 2014-02-13 13:12

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 Journal - Wed, 2014-02-12 14:22

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

Linux Journal - Mon, 2014-02-10 16:29

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>>

Anubis, the God of Dead Bitcoin Miners

Linux Journal - Thu, 2014-02-06 11:43

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>>

Girls and Software

Linux Journal - Tue, 2014-02-04 15:14

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>>

Rails and PostgreSQL

Linux Journal - Wed, 2014-01-29 14:37

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

Linux Journal - Tue, 2014-01-28 14:26

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

Linux Journal - Mon, 2014-01-27 14:36

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

Linux Journal - Wed, 2014-01-22 14:25

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 (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 Journal - Fri, 2014-01-17 12:52

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>>
