Everpad

By Shawn Powers 

It seems as though all the cool kids are addicted to Evernote. I'm not quite that cool, but I have been trying hard to convert to a paperless lifestyle. Evernote admittedly is a great tool for archiving information. When I bought my Nexus 7, I also bought a subscription to Evernote Premium. more>>

Elliptic Curve Cryptography

By Joe Hendrix

Android Candy: Gurk—8 Bits of Awesome

By Shawn Powers 

Gurk really shouldn't be awesome. The controls are awkward on-screen arrow keys. The graphics make the original Nintendo look state of the art in comparison. The gameplay is slow.

And yet I just spent two hours straight playing it! more>>

Free and Open—and Their Opposites

By Doc Searls 

A linguistic look at some tenets of Linux.

Merriam-Webster defines a tenet as "a principle, belief, or doctrine generally held to be true; especially one held in common by members of an organization, movement, or profession." As it happens, Linux is claimed by two doctrines that are to some degree at odds: those of free software and open source. This contention began when Eric S. Raymond published "Goodbye, 'free software'; hello, 'open source'", on February 8, 1998. Here's an excerpt: more>>

Configuring One-Time Password Authentication with OTPW

By Todd A. Jacobs 

Password authentication contains a lot of assumptions about security and trust. Encrypted SSH tunnels and public key verification are two common ways to ensure that your password is not compromised in transit. But, what if it's the computer you're currently typing on that can't be trusted? more>>

How to Deploy A Server

By Kyle Rankin 

When I write my column, I try to stick to specific hacks or tips you can use to make life with Linux a little easier. Usually, I describe with pretty specific detail how to accomplish a particular task including command-line and configuration file examples. This time, however, I take a step off this tried-and-true path of tech tips and instead talk about more-general, high-level concepts, strategies and, frankly, personal opinions about systems administration. more>>

Android Candy: Pocket

By Shawn Powers 

Most people are familiar with Instapaper and Read It Later. Those types of services are great for tagging Web articles for later reading, and in the case of Read It Later (now called "Pocket"), they do a wonderful job of copying articles off-line for reading when the Internet isn't available. more>>

Speed Up Your Drupal Development Using Installations and Distributions

By Oliver Davies 

Do you find yourself repeating the same steps whenever you start a new Drupal project? Do you always download and enable the same modules, and make the same configuration changes every time? As we start doing more and more Drupal projects at Nomensa, I noticed that we were doing exactly this, so I started to look into ways to streamline our initial project setup process. more>>

Design Your Own Rocket

By Joey Bernard 

A lot of the software packages I've covered in recent articles have been focused strictly on doing computations on your machine, separate from the real world. So in this article, I explore how to use your computer to design something you can build and use in the real world: your own model rocket. more>>

Shell Game

By Shawn Powers 

Many of the cool things in Linux Journal require the use of the command line. For us Linux users, that's generally not a big deal, because we have a terminal window readily available. Some of the time, however, it's helpful to have a shell account on an Internet host somewhere. more>>

Phonegap Application Development

By Mike Diehl 

How many times have you heard, "there's an app for that"? But sometimes, there actually isn't "an app for that", or the apps that do exist don't meet your needs. As Linux users, we tend to like to scratch our own itches, and if that means we write some code to do it, so be it. more>>

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
