Numeric Relativity with the Einstein Toolkit

This post finds us at the cutting edge of physics, numerical general relativity. Because we haven't perfected mind-to-mind transmission of information, we won't actually be able to cover in any real detail how this all works. more>>

iSCSI Lab

Creating Software-backed iSCSI Targets in Red Hat Enterprise Linux 6

Studying for certification exams can be an adventure. Even more so when the certification exam is a hands-on, performance-based exam. The quandry most people I know fall into, is that to effectively study for such an exam, you need access to a lab environment with elements that may be beyond the scope of the average Linux enthusiast. One such element is iSCSI.  more>>

Maxima

Maximum Calculus with Maxima

We looked at Maxima in the February 2011 issue to do algebra and rearrange some equations. But those aren't the only tricks up Maxima's sleeve. This month, I describe how Maxima can help with differential equations, but I'm going to leave out some of the intermediate results to save some space. more>>

Secondary Window Tools in Scribus

Scribus is designed so that the main window shows only the document you are designing. Other tools are positioned to secondary windows, where they have all the room they need for detailed settings. You may discover some of these secondary windows via menus and toolbars as you work, but not all. more>>

Drop Your Dropbox and SparkleShare Instead!

We love Dropbox here at Linux Journal. It's cross-platform, offers a decent free offering and generally "just works". It has some problems though. Dropbox is proprietary. Dropbox stores a copy of your data in its own data repositories. Dropbox is limited in size, especially with its free accounts. more>>

Tweaking text in Scribus

In word processors, users generally settle for an appearance that is good enough. By contrast, in a design application like Scribus, you have the tools to adjust the layout until it is exactly the way you want. more>>

Silly Programs

Those of us who have been using Linux for a long time all know the joy of silly programs like xeyes. One of my favorites, however, is good old xsnow. Whether you love the cold weather or live in Florida and like to ski on occasion, xsnow will add some winter fun to your desktop. The xsnow program has been around forever and is surely available for your distribution. more>>

Using Styles in Scribus

If you don't include master pages (which are really styles under another name), then Scribus supports three types of hierarchial styles: lines, character, and paragraph. As in any other self-respecting word processor or layout application, these styles allow you to apply detailed sets of formatting options quickly, without having to change each instance of a formatting option individually. 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.

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.
