diff -u: What's New in Kernel Development

David Herrmann wanted to disable the virtual terminal subsystem in order to save space on a kernel that didn't need a VT. But, he still wanted to see kernel oops output for debugging purposes. The problem was that only the VT subsystem would display oops output—and he'd just disabled it. more>>

It seems like every day there's a new mobile game that takes the world by storm. Whether it's Flappy Bird or Candy Crush, there's something about simple games that appeals to our need for quick, instant gratification. more>>

Super Pi Brothers

I don't game as much as I used to. Although I've certainly spent countless hours of my life in front of a Nintendo, SNES, or after that, playing a first-person shooter on my computer (Linux only, thank you), these days, my free time tends to go toward one of the many nongaming hobbies I've accumulated. more>>

A Process for Managing and Customizing HPC Operating Systems

Non-Linux FOSS: My Portable Windows Lab

Portable apps aren't anything new. There are variations of "single executable apps" for most platforms, and some people swear by keeping their own applications with them for use when away from home. I don't usually do that, as most of what I do is on-line, but there is one exception: security. more>>

Scientific Graphing in Python

In my last few articles, I looked at several different Python modules that are useful for doing computations. But, what tools are available to help you analyze the results from those computations? Although you could do some statistical analysis, sometimes the best tool is a graphical representation of the results. more>>

Sicker Than Sickbeard?

When I wrote about Usenet and Sickbeard a while back, I got many e-mails that I had broken the first rule of Usenet: don't talk about Usenet. I'm a sucker for freedom though, and I can't help but share when cool programs are available. This month, I switched from Sickbeard to NZBDrone for managing my television shows. more>>

Linux Containers and the Future Cloud

Linux-based container infrastructure is an emerging cloud technology based on fast and lightweight process virtualization. It provides its users an environment as close as possible to a standard Linux distribution. more>>

rc.local, Cron Style

Occasionally as seasoned Linux users, we run across simple things we never knew existed—and are amazed. Whether it's tab autocompletion, sudo !! for when you forgot to type sudo or even recursive file listing with ls, the smallest tricks can be so incredibly useful.

June 2014 Issue of Linux Journal: Networking

I tend to be a fairly funny guy. Well, at least I think I'm funny. My kids might disagree. The thing is, it's hard to find a group of people to understand obscure networking jokes. more>>

Resizing Images with ImageMagick

Sure, you can open up a graphics program like GIMP and resize an image, but what if you want to resize 10, 50 or 200 images? ImageMagick's convert program is just what you need. more>>

A Little GUI for Your CLI

I've tried pretty much every IRC client available for both Linux and OS X. (I use both platforms during my day job.) No matter how many times I try to find a GUI application that meets my needs, I always turn back to Irssi. more>>

Command-Line Cloud: rss2email

In my last article, I started a series called Command-Line Cloud. The intent of the series is to discuss how to use the cloud services we are faced with these days without resorting to a Web browser. I spend most of my time on the command line, so that's where I'd most like to interface with cloud services. more>>

The Growing Role of UEFI Secure Boot in Linux Distributions

With the increasing prevalence of open-source implementations and the expansion of personal computing device usage to include mobile and non-PC devices as well as traditional desktops and laptops, combating attacks and security obstacles against malware is a growing priority for a broad community of vendors, developers and end users. more>>

Take on "dependency hell" with Docker containers, the lightweight and nimble cousin of VMs. Learn how Docker makes applications portable and isolated by packaging them in containers based on LXC technology. more>>

Non-Linux FOSS: Git Yer Tortoise On!

Git has become the most popular version-tracking platform around for open-source projects. Whether you're using GitHub, Gitorious, Bitbucket or similar, or even if you're hosting the git repository yourself, accessing the code is something us Linux users take for granted. 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.

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.
