HOW-TOs

Temper Pi

By Kyle Rankin 

It was inevitable. Back when the Raspberry Pi was announced, I knew I eventually would use one to power a beer fridge. more>>

How'd Ya Do That?

I tend to read science fiction or fantasy for entertainment and/or escape from reality. more>>

Advanced OpenMP

By Joey Bernard 

Because the August issue's theme is programming, I thought I should cover some of the more-advanced features available in OpenMP. more>>

Multi-Booting the Nexus 7 Tablet

By Bill Childers 

Anyone who knows me well enough knows I love mobile devices. Phones, tablets and other shiny glowing gadgets are almost an addiction for me. I've talked about my addiction in other articles and columns, and Kyle Rankin even made fun of me once in a Point/Counterpoint column because my household has a bunch of iOS devices in it. more>>

Pythonic Parsing Programs

By Matt Harrison 
Creed of Python Developers

Pythonistas are eager to extol the lovely virtues of our language. Most beginning Python programmers are invited to run import this from the interpreter right after the canonical hello world. One of the favorite quips from running that command is: more>>

Cribbage: Sorting Your Hand

By Dave Taylor 

We've been working on writing code for the game Cribbage, and last time, I created the code needed to pick a random subset of six cards out of a "deck" and display them in an attractive format—like this: $ sh cribbage.sh Card 0: 7C Card 1: 5H Card 2: 9H Card 3: 10S Card 4: 5D Car more>>

Sometimes It's Okay to Point

By Shawn Powers 

Mom always said, "It's not nice to point." I'd argue Mom didn't manually enter long, cumbersome URLs, however. We're all familiar with services like TinyURL, but because we're Linux folks, we tend to prefer doing such things on our own. As with almost everything in Linux, there's more than one way to skin a cat, and in this article, I explore a bunch. more>>

Lock-Free Multi-Producer Multi-Consumer Queue on Ring Buffer

By Alexander Krizh... 

Nowadays, high-performance server software (for example, the HTTP accelerator) in most cases runs on multicore machines. Modern hardware could provide 32, 64 or more CPU cores. In such highly concurrent environments, lock contention sometimes hurts overall system performance more than data copying, context switches and so on. more>>

Counting Cards: Cribbage

By Dave Taylor 

I've spent the past few months reviewing shell scripting basics, so I think it's time to get back into an interesting project. more>>

Designing Electronics with Linux

By Joey Bernard 

In many scientific disciplines, the research you may be doing is completely new. It may be so new that there isn't even any instrumentation available to make your experimental measurements. In those cases, you have no choice but to design and build your own measuring devices. more>>

Dynamic DNS—an Object Lesson in Problem Solving

By Shawn Powers 

The other day in the Linux Journal IRC room (#linuxjournal on Freenode), I was whining to the channel about no-ip.com deleting my account without warning. My home IP address hadn't changed in a couple months, and because there was no update, it appeared abandoned. more>>

Using Salt Stack and Vagrant for Drupal Development

By Ben Hosmer 

What if, just like Bill Murray in Groundhog Day, you could wake up to a fresh and identical development environment completely free of yesterday's experiments and mistakes? Vagrant lets you do exactly that. more>>

Making Linux and Android Get Along (It's Not as Hard as It Sounds)

By Aaron Peters 

Many free software fans, if they were like me, breathed a collective sigh of relief when the Android operating system hit the market. more>>

Drupal Is a Framework: Why Everyone Needs to Understand This

By Diana Dupuis 

Everyone planning and building Web solutions with Drupal benefits from understanding what a "hook" is—and why Drupal is not a CMS. more>>

Home, My Backup Data Center

By Kyle Rankin 

New Linux users often ask me "what is the best way to learn about Linux?" My advice always comes down to this: install and use Linux (any distribution will do but something stable works better), and 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.

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?

They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
