Awk is one of the oldest tools in the Unix and Linux user's toolbox. Created in the 1970s by Alfred Aho, Peter Weinberger, and Brian Kernighan (the A, W, and K of the tool's name), awk was created for complex processing of text streams. It is a companion tool to sed, the stream editor, which is designed for line-by-line processing of text files. Awk allows more complex structured programs and is a complete programming language. This article will explain how to use awk for more structured and complex tasks, including a simple mail merge application.

Ansible has long been seen as more than configuration management—it's an orchestrator more than anything, a conductor of the orchestra rather than playing a singular instrument. Since realising this, various tech communities have used Ansible to automate some interesting technology arenas.

It was fun to work at a large web property in the late 1990s and early 2000s. My experience takes me back to American Greetings Interactive, where on Valentine's Day, we had one of the top 10 sites on the internet (measured by web traffic). We delivered e-cards for AmericanGreetings.com, BlueMountain.com, and others, as well as providing e-cards for partners like MSN and AOL.

Port knocking is a method of dynamically opening network ports by "knocking" (i.e. connecting) on a predefined sequence of ports. This is especially useful for obscuring an open network port from port scanning since the port in question will be closed unless the port knocking sequence is executed.

Graphical user interface (GUI) test automation is broken. Regression testing is not testing; it's version control for a software's behavior. Here's my assertion: test automation without assertions works better!

After you've established a positive reputation in an open community—hopefully, as we discussed in our previous article, by being an active member in and contributing productively to that community—you'll have built up a healthy "bank balance" of credibility you can use to influence the direction of that community. What does this mean in concrete terms? It means you can contribute to the decisions the community makes.

I have been using Python since it was a little-known language in 1998. It was a time when Perl was quite popular in the open source world, but I believed in Python from the moment I found it. My parents like to remind me that I used to say things like, "Python is going to be a big deal" and "I'll be able to find a job using it one day." It took a while, but my predictions came true.
