In this article, I'm diving into chemistry again. Many packages, both commercial and open source, are available to make chemistry calculations at the quantum level. The one I cover here is gromacs (http://www.gromacs.org). It should be available for your distribution via its package manager. more>>

In this tutorial, the fifth in a series of seven tutorials covering intermediate network administration on Linux, David Mertz continues preparing you to take the Linux Professional Institute Intermediate Level Administration (LPIC-2) Exam 202. By following this tutorial, you will examine several protocols' centralized configuration of network settings on clients within a network. DHCP is widely used to establish basic handshaking to clients machines such as assigning IP addresses. At a higher level, NIS and (more often) LDAP are used for arbitrary shared information among machines on a network. This tutorial also discusses PAM, which is a flexible, networked, user authentication system.

Linux has been described as one of the most secure operating systems available, but the National Security Agency (NSA) has taken Linux to the next level with the introduction of Security-Enhanced Linux (SELinux). SELinux takes the existing GNU/Linux operating system and extends it with kernel and user-space modifications to make it bullet-proof. If you're running a 2.6 kernel today, you might be surprised to know that you're using SELinux right now! This article explores the ideas behind SELinux and how it's implemented.

Going back to last year there's been the "Glamor Acceleration" project out of Intel to accelerate the 2D operations within X using OpenGL on Mesa. This is similar to the Xorg state tracker approach and while it's not yet enabled by default, Intel OTC developers have been making much progress in recent months. In this article is a look at the recent Glamor update while comparing it to the stock Intel UXA acceleration as well as to the other experimental acceleration option: Intel SNA.

Two years after its initial attempt to sell Nexus smartphones directly to consumers flopped, Google is apparently trying to revive the strategy. This time, though, it's added a few new touches. It's going to work with up to five device manufacturers at a time to create a portfolio of Nexus-line devices that include smartphones and tablets.

A few weeks back, I was whining that although Doctor Who was available on Amazon Prime streaming, I didn't have any way to watch it on my television. Thankfully, my friend Richard Servello pointed me to the bluecop repo for XBMC. Not only does bluecop support Amazon Prime streaming, but it also has add-ons for Hulu and countless other network-video-streaming collections.

SugarCon, the SugarCRM user meeting held in San Francisco a couple of weeks ago, did some important things for Sugar. It was a coming out party of sorts for a company with a distinct business model and strategy, namely open source. It was also validation of that strategy and, for many, a new realization of what open source means.

Bitcoin mining is so last year. Put your expensive GPU to use cracking passwords.

When the Bitcoin mining craze hit its peak, I felt the tug to join this new community and make some easy money. I wasn't drawn only by the money; the concepts behind Bitcoin mining intrigued me, in particular the new use of graphics processors (GPUs). With a moderately expensive video card, you could bring in enough money to pay off your initial investment and your electricity bill in a relatively short time.
