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>>

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>>

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>>

Blu-ray Encryption—Why Most People Pirate Movies

I get a fair amount of e-mail from readers asking how a person could do "questionable" things due to limitations imposed by DRM. Whether it's how to strip DRM from ebooks, how to connect to Usenet or how to decrypt video, I do my best to point folks in the right direction with lots of warnings and disclaimers. The most frustrating DRM by far has been with Blu-ray discs. more>>

Returning to Ground from the Web's Clouds

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale?
