December 2014 Issue of Linux Journal: Readers' Choice

The Best of the Best

I love the Readers' Choice issue. I jokingly say it's because all the work is done by the community, but honestly, it's because I love hearing the feedback from everyone. Year after year, I inevitably learn about a new technology or application, and I'm usually surprised by at least one of the voting results. more>>

Coolest Things You've Done with Linux

In our 2014 Readers' Choice Awards, we asked readers to tell us the coolest thing they've done with Linux. There were so many great responses, but we didn't have room for all of them in the magazine, so we're listing more of the best ones here. Enjoy!

Building my procmail pre-spam spam filter back in mid-late 90s.

Non-Linux FOSS: XAMP

One of my career iterations put me in charge of a Windows server that had Apache and PHP installed on it to serve as a Web server for the corporate intranet. Although I was happy to see Apache used as the Web server dæmon, the installation on the Windows server was the most confusing and horrifying mess I've ever seen. more>>

The Awesome Program You Never Should Use

I've been hesitating for a couple months about whether to mention sshpass. Conceptually, it's a horrible, horrible program. It basically allows you to enter an SSH user name and password on the command line, so you can create a connection without any interaction. A far better way to accomplish that is with public/private keypairs. more>>

Days Between Dates?

Alert readers will know that I'm working on a major revision to my popular Wicked Cool Shell Scripts book to come out later this year. Although most of the scripts in this now ten-year-old book still are current and valuable, a few definitely are obsolete or have been supplanted by new technology or utilities. No worries—that's why I'm doing the update. more>>

Synchronize Your Life with ownCloud

Like most families these days, our family is extremely busy. We have four boys who have activities and appointments. My wife and I both have our own businesses as well as outside activities. For years, we've been using eGroupware to help coordinate our schedules and manage contacts. The eGroupware system has served us well for a long time. However, it is starting to show its age. more>>

A GUI for Your CLI?

For new Linux users, the command line is arguably the most intimidating thing. For crusty veterans like me, green text on a black background is as cozy as fuzzy slippers by a fireplace, but I still see CLI Companion as a pretty cool application. more>>

Android Candy: Party Like It's 1994!

I really stink at video games. I write about gaming occasionally, but the truth of the matter is, I'm just not very good. If we play Quake, you'll frag me just about as often as I respawn. I don't have great reflexes, and my coordination is horrible. more>>

An Introduction to OpenGL Programming

OpenGL is a well-known standard for generating 3-D as well as 2-D graphics that is extremely powerful and has many capabilities. OpenGL is defined and released by the OpenGL Architecture Review Board (ARB).

This article is a gentle introduction to OpenGL that will help you understand drawing using OpenGL. more>>

diff -u: What's New in Kernel Development

Hardware errors are tough to code for. In some cases, they're impossible to code for. A particular brand of hardware error is the Machine-Check Exception (MCE), which means a CPU has a problem. On Windows systems, it's one of the causes of the Blue Screen of Death. more>>

Tomahawk, the World Is Your Music Collection

I don't listen to music very often, but when I do, my tastes tend to be across the board. That's one of the reasons I really like Pandora, because the music selection is incredible (in fact, I can't recommend the Pithos client for Pandora enough—I've written about it in past issues). Unfortunately, with Pandora, you don't get to pick specific songs. more>>

November 2014 Issue of Linux Journal: System Administration

Folger's Crystals

Every time I write a Bash script or schedule a cron job, I worry about the day I'll star in my very own IT version of a Folger's commercial. Instead of "secretly replacing coffee with Folger's Instant Crystals", however, I worry I'll be replaced by an automation framework and a few crafty FOR loops. more>>

Weapons of MaaS Deployment

My Day with Canonical

I've been researching OpenStack deployment methods lately and so when I got an email from Canonical inviting me to check out how they deploy OpenStack using their Metal as a Service (MaaS) software on their fantastic Orange Box demo platform I jumped at the opportunity. more>>

Ubuntu & SUSE & CentOS, Oh My!

Ubuntu & SUSE & CentOS, Oh My!

It's Halloween week, and the big names in Linux are determined not to disappoint the trick-or-treaters. No less than three mainline distributions have released new versions this week, led by perennially-loved-and-hated crowd favourite Ubuntu. more>>

Easy Watermarking with ImageMagick

Let's start with some homework. Go to Google (or Bing) and search for "privacy is dead, get over it". I first heard this from Bill Joy, cofounder of Sun Microsystems, but it's attributed to a number of tech folk, and there's an element of truth to it. Put something on-line and it's in the wild, however much you'd prefer to keep it under control. more>>
