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>>

Creating and Theming a Custom Content Type with Drupal 7

By Danny Englander 

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

By Doc Searls 

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

By Shawn Powers 

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

By Shawn Powers 

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

By James Slocum 

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

By Kyle Rankin 

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

By Shawn Powers 

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>>

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?
