How YARN Changed Hadoop Job Scheduling

Scheduling means different things depending on the audience. To many in the business world, scheduling is synonymous with workflow management. Workflow management is the coordinated execution of a collection of scripts or programs for a business workflow with monitoring, logging and execution guarantees built in to a WYSIWYG editor. more>>

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

High-performance computing (HPC) for the past ten years has been dominated by thousands of Linux servers connected by a uniform networking infrastructure. The defining theme for an HPC cluster lies in the uniformity of the cluster. more>>

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. Not long ago, I had one of those moments. more>>

Linux is Everywhere...So where do we go from here?

We all know that Linux has changed the world...in small ways and large. One of the ways it's changed the world is by changing the way work gets done in corporations, big and small, around the world. As with the computer itself, the effects of ever-advancing Linux seem evolutionary and "slow & steady" from day to day. more>>

June 2014 Issue of Linux Journal: Networking

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
