SIGALRM Timers and Stdin Analysis

It's not hard to create functions to ensure that your script doesn't run forever. But what if you want portions to be timed while others can take as long as they need? Not so fast, Dave explains in his latest Work the Shell. more>>

Speed Up Your Drupal Development Using Installations and Distributions

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

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

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

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>>

Contest Takes SXSW Experience Outside of Austin

Spring Break is upon us, and the destination of choice for geeks to take their annual spring sojourn is the South by Southwest Interactive Festival in Austin.  Not all those who wish to go will get the expense approved and instead will end up stuck sifting through a barrage of blog posts and event hashtags in order to get their SXSW fix. more>>

Creating and Theming a Custom Content Type with Drupal 7

One of the great new things about Drupal 7 is that it's now easier to customize your site content. In Drupal 6, you typically had to use the CCK (Content Construction Kit) module for fine-grained control in customizing content, but that has been folded into core for Drupal 7. Drupal 7 is now a true content management framework (CMF). more>>

Android for Independence

At some point in the early 2000s, I got my wife a Nokia phone with a keyboard, so we could text each other. It was a great little phone, not hard to use or understand, but she texted me only once with it, to send the word "no". Then, in late 2007, not long after the iPhone came out, she told me she wanted one. Why? more>>

Finally, "The Cloud" Means Something

Few jargonistic terms have annoyed me as much as, "The Cloud." When the term was first coined, its meaning was ambiguous at best. For some companies, it meant shared web hosting (but with a cooler sounding name). For others it was simply, "let us host your servers in our datacenter, which we now refer to as a cloud." more>>

Crashplan, the Only Reason I Install Java

I'm the sort of person who doesn't like to install Java. I actually don't like to install Flash either, but it's still tough to survive browsing the Internet without Flash installed. There is one program that makes me break my own rules, however, and that's Crashplan. more>>

Google Dart Article Correction

I'm the author of the article "Introducing Dart, the New Web Language from Google" in the March 2013 issue. I wrote the article in late December and submitted the article in early January of this year. During the time I was writing it, I was using Dart M2 (version 0.2.9.9). I made sure to have my colleagues check over my code and worked to make sure that everything was perfect! more>>

Troubleshooting with Telnet

Poor telnet, it used to be the cool kid on the block. It was the program all sysadmins turned to when they needed to connect to a remote server. Telnet just wasn't that good at keeping a secret—all communication went over plain text—so administrators started switching to SSH for encrypted remote shell sessions. more>>

Remembering Spidey

Back before Google was born, and even longer before it became a verb, the World Wide Web was often searched by a little spider on a surfboard. more>>

Pwn Your Phone

I've owned two different Android phones since they first were released, and I eventually rooted both of them. My Droid (original) was such a popular phone that rooting it was very simple. I used my rooted Droid until it wore out and rebooted every time I slid open the keyboard. My second Android phone, the Samsung Galaxy S2, is the phone I have right now. more>>

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.
