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>>

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>>

Obsession with Big Data has gotten out of hand. Here's how. 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>>

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>>

Mac? Only if it's a vim macro. more>>

Promise Theory—What Is It?

During the past 20 years, there has been a growing sense of inadequacy about the "command and control" model for managing IT systems. Years in front of the television with a remote control have left us hard pressed to think of any other way of making machines work for us. 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. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

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.
