Albert Einstein

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>>

Gnome 3 Desktop

The Linux Desktop: We've Arrived.

Linux Desktop articles are all over the place. I can hardly open up a browser without tripping over one. Most of them are negative whine-fests, complaining that Linux is too hard for new users, or has become too dumbed-down for technical users, or the fonts are ugly, or the next generation desktop environments are too different, or... well I could go on, but I think you get the point. more>>

Linux Gaming: OpenClonk

Until recently, I had presumed that a Clonk was the sound that my hard drive made just before I realized that I hadn't backed it up properly. However, in this case, a Clonk is a tiny chap who can jump, climb and fire weapons in the service of reaching his goal. OpenClonk runs on Linux and is the latest in a series of side-view platform games that started life as a DOS shareware series. more>>

Minecraft. Not free.

Friday Fun: Minecraft

This week's game is one that isn't free. In any sense. It is closed source, and requires payment to even try it out. Why would we mention such a game here at Linux Journal? 2 reasons:

1) It works quite well in Linux more>>

Archiving CDs to ISO from the Command Line

A few weeks ago I was working on a PC when I needed to grab the motherboard driver CD.  In a perfect world, the CD would be located in a nice protective sleeve, safely kept away from the nasty elements that encompass the IT tech area (read: coffee, scratches, and the occasional jelly doughnut).  But in this case, it appeared someone had taken this CD and wiped it a more>>

Safer Access without Passwords

How do you make sure that your passwords are safe? You can make them longer, complicate them by adding odd characters, making sure to use different passwords for each user account that you have. Or, you can simply skip them all together. more>>

Webian Shell: Prototype Web-Based Shell

Webian Shell is a web-based shell that is designed to run full-screen and function as the primary user interface for your computer. At the moment, it's still at the proof of concept stage, but 0.1 is runnable without making any modifications to your system. As it features some interesting ideas, it's worth having a play around with. more>>
