Gnuplot—the Grandfather of Graphing Utilities

In these columns, I have covered several different scientific packages for doing calculations in many different areas of research. I also have looked at various packages that handle graphical representation of these calculations. But, one package that I've never looked at before is gnuplot (http://www.gnuplot.info). more>>

Plex

Android Candy: Plex

Anyone with an iPhone probably is familiar with the AirVideo application. Basically, it's the combination of a server app that runs on your Windows or OS X machine, and it serves video over the network to an AirVideo application on your phone. It's extremely popular, and for a good reason—it works amazingly well. more>>

Great Feedback!

The feedback I've gotten on my "Taming the Tablet" column in issue 226 has been amazing. Thanks to everyone who has sent me their tablet setup, their experiences, and their thanks. It makes writing my column feel more like a conversation than a lecture. :)

N900 with a Slice of Raspberry Pi

It may not come as a surprise to anyone who regularly reads my column that I tried to be first in line to order the Raspberry Pi. I mean, what's not to like in a $35, 700MHz, 256MB of RAM computer with HDMI out that runs Linux? In the end, I didn't make the first batch of 10,000, but I wasn't too far behind either. more>>

IBM's New SMB Cloud-making Machines

This week IBM released a bunch of new hardware, including 8 new Power Systems, 3 PureSystems models, and new storage technology. This is good news for small and medium businesses, because it means the same powerful hardware that powers Watson (http://www-03.ibm.com/innovation/us/watson/) is now available at prices designed to compete with commodity hardware from other vendors. more>>

Switching to Chrom(ium)

For someone who works with, writes about and teaches cutting-edge technologies, I tend to be a bit of a laggard when adopting new ones. I upgrade my laptop and servers very conservatively. more>>

Introducing Grive

Earlier this year, Google introduced its Google Drive cloud storage service. more>>

Native(ish) Netflix!

The folks over at http://www.iheartubuntu.com recently put up a challenge to the Linux community to get Netflix to work natively under our beloved OS. Thankfully, Erich Hoover stepped up to the challenge and patched the Wine Project in a way to allow Firefox/Silverlight to be installed and actually work with Netflix's DRM'd Silverlight! more>>

Android System Administration Utilities

“Change is inevitable in a progressive society. Change is constant” Benjamin Disraeli 1867. Quite a fitting quote if I say so myself. When I started in systems administration back in the mid 90’s everything was done either remoted in from your desktop, a server, or you plugged a terminal into the back of the server. more>>

February 2013 Issue of Linux Journal: System Administration

Digital Duct Tape

I've had enough system administration jobs to know that companies tend to take drastically different approaches to how they handle technology. more>>

Scientific Visualization with NCL

Many of my previous articles have looked at software packages that do scientific calculations and generate scientific results. But, columns of numbers are nearly impossible to make sense of—at least, by regular human beings. So what can you do? The answer is visualization. more>>

Aaron Swartz

Picking Up Aaron Swartz's Dropped Flags

My first quality time with Aaron Swartz was at the last Comdex, in the Fall of 2002. He had just turned 16, but looked about 10. His old Mac laptop featured a screen with no working backlight. Only he could read it, which he rationalized, with a smile, as a "security precaution." When I asked him about school, he said he had moved on. more>>

On Data Tagging

Pick up most items, from the soup can, to the library book, and you will find a data tag. In most cases, that tag is the simple, ubiquitous bar code that seems to have been around forever. more>>

Shawn demonstrates how to tunnel web traffic through a SOCKSproxy using SSH.

Android Candy: WiFi Analyzer

I have a new day job, and as part of the hiring package, I was issued a smartphone. I'm a little bitter that it doesn't include a tethering plan, but that doesn't upset me nearly as much as the lack of Wi-Fi analysis apps. See, my new job issued me an iPhone. I really like the iPhone (it's true, I can't lie), but in order to scan Wi-Fi, I'd have to jailbreak my phone! 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.
