Siege Your Servers!

Setting up Web servers is fairly simple. In fact, it's so simple that once the server is set up, we often don't think about it anymore. It wasn't until I had a very large Web site rollout fail miserably that I started to research a method for load-testing servers before releasing a Web site to production. more>>

Android Candy: Waze

I have a love/hate relationship with Waze. The idea of peer collaboration regarding traffic, combined with the technology to accomplish it on an enormous scale is truly amazing. Yet, every time I've used Waze myself, it's been an exercise in frustration. It has insisted I turn left off a bridge, and then it refused to reroute me when I didn't. more>>

SciPY for Scientists

In my last article, I looked at NumPY and some of its uses in numerical simulations. Although NumPY does provide some really robust building blocks, it is a bit lacking in more sophisticated tools. SciPY is one of the many Python modules that build on NumPY's. more>>

AutoSSH, for All Your <CONNECTION LOST>

I love SSH. I mean, I really, really love SSH. It's by far the most versatile, useful, amazingly powerful tool in my system administration quiver. One of the problems with SSH, however, is that when it dies, it doesn't automatically recover. Don't get me wrong. more>>

A Cool Project for Microsoft: Adopt Linux

"Do you know Linux? WE AE HIRING!" That's what billboards from HostGator have been saying for the past several years. That company is not alone. Demand for Linux talent is high and getting higher. more>>

May 2014 Issue of Linux Journal: Cool Projects

Cooler Than Minnesota in January

By the time this issue goes to press, the snow in my backyard probably will be only knee deep in the shade. more>>

Debugging Web Sites

I know, I'm in the middle of a series of columns about how to work with ImageMagick on the command line, but when other things arise, well, I imagine that a lot of you are somehow involved in the management of servers or systems, so you all understand firefighting. more>>

BirdCam, Round Two

In the October 2013 issue, I described the hardware and software I used to create my "BirdTopia Monitoring Station", more commonly called BirdCam. If you've been visiting BirdCam recently, which a surprising number of folks have been doing, you'll notice quite a few changes (Figure 1). In this article, I describe the upgrades, the changes and some of the challenges along the way. more>>

Linux Graphics News

At the start of this quarter we looked at how 2013's graphics developments were more incremental than revolutionary, perhaps with the need for LTS stability in mind. Things are looking quite different this year, with several major changes quietly under way. more>>

New Products

Please send information about releases of Linux-related products to newproducts at linuxjournal.com or New Products c/o Linux Journal, PO Box 980985, Houston, TX 77098. Submissions are edited for length and content.

Quantum Cryptography

Classical cryptography provides security based on unproven mathematical assumptions and depends on the technology available to an eavesdropper. But, these things might not be enough in the near future to guarantee cyber security. We need something that provides unconditional security. We need quantum cryptography. more>>

Command-Line Cloud: gcalcli

If you follow my columns in Linux Journal, you probably are aware that I'm a big fan of the command line. When it comes to getting things done efficiently, most of the time the command line can't be beat. more>>

Image Manipulation with ImageMagick

I've spent a lot of time in my column talking about text processing and analysis, with the basic assumption that if you're using the command line, you're focused on text. more>>

Non-Linux FOSS: Angry IP

The de facto standard for port scanning always has been the venerable Nmap program. The command-line tool is indeed very powerful, but I've only ever seen it work with Linux, and every time I use it, I need to read the man page to figure out the command flags. more>>

Encrypting Your Cat Photos

The truth is, I really don't have anything on my hard drive that I would be upset over someone seeing. I have some cat photos. I have a few text files with ideas for future books and/or short stories, and a couple half-written starts to NaNoWriMo novels. It would be easy to say that there's no point encrypting my hard drive, because I have nothing to hide. more>>

Numerical Python

For the past few months, I've been covering different software packages for scientific computations. For my next several articles, I'm going to be focusing on using Python to come up with your own algorithms for your scientific problems. more>>

Speed Test for Nerds

Most people with Internet access in their houses have visited a speed-test Web site to make sure they're getting somewhere close to the speed they're overpaying for. I'm paying more than $100 a month for my business-class connection from Charter, so on a regular basis, I make sure I'm getting the advertised speed. more>>

DNSSEC Part II: the Implementation

This article is the second in a series on DNSSEC. In the first one, I gave a general overview of DNSSEC concepts to lay the foundation for this article, which discusses how to enable DNSSEC for a zone using BIND. more>>

Pro Video Editing with Pitivi

Several decent video editors are available on the Linux platform. Kdenlive, OpenShot, Cinelerra and Pitivi are those that come to mind as "big players" in an admittedly small market. I've used them all through the years, with varying levels of success. 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.
