I don't know how many readers know this, but my very first Linux Journal column ("Browse the Web without a Trace", January 2008) was about how to set up and use Tor. Anonymity and privacy on the...

Adminer—Better Than Awesome!

I've always loved PHPMyAdmin for managing MySQL databases. It's Web-based, fairly robust and as powerful as I've ever needed. Basically, it's awesome. Today, however, I discovered something better than awesome: Adminer. Although it is conceptually identical to PHPMyAdmin, it is far simpler and far more powerful. How can it be both? more>>

It Actually Is Rocket Science

I've never once made a model rocket. I've always wanted to, but apart from "tube with explodey rocket part", I really didn't know where to start with designing. I recently found an open-source application that should help me with my lack of rocket science know-how: OpenRocket. more>>

Android Candy: Repix, Not Just Another Photo App

Apps like Instagram have made photo filters commonplace. I actually don't mind the vintage look for quick cell-phone snapshots, but a filter can do only so much. At first glance, Repix is another one of those "make your photo cool" apps that does little more than add a border and change saturation levels. more>>

Dolphins in the NSA Dragnet

There's an old quote from Jamie Zawinkski that goes: "Some people, when confronted with a problem, think ‘I know, I'll use regular expressions.’ Now they have two problems." Even people like me who like regular expressions laugh at the truth in that quote, because we've seen the consequences when someone doesn't think through the implications of a poorly written pattern. When some people write a bad pattern, they end up with extra lines in a log file. When the NSA does it, they capture and retain Internet traffic on untold numbers of innocent people. more>>

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>>

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.
