Dave continues with his shell-script L33t translator.In my last article, I talked about the inside jargon of hackers and computer geeks known as "Leet Speak" or just "Leet". Of course, that's a shortened version of the word Elite, and it's best written as L33T or perhaps L337 to be ultimately kewl. But hey, I don't judge.

It's occasionally useful to have a block of Perl code that you use only for debugging or development tweaking. That's fine, but having blocks like this can be expensive to performance, particularly if the decision whether to execute it is made at runtime. read more

My reaction when I first came across the terms counter and gauge and the graphs with colors and numbers labeled "mean" and "upper 90" was one of avoidance. It's like I saw them, but I didn't care because I didn't understand them or how they might be useful. Since my job didn't require me to pay attention to them, they remained ignored. That was about two years ago. As I progressed in my career, I wanted to understand more about our network applications, and that is when I started learning about metrics.

Managing an open source project is challenging work, and the challenges grow as a project grows. Eventually, a project may need to meet different requirements and span multiple repositories. These problems aren't technical, but they are important to solve to scale a technical project. Business process management methodologies such as agile and kanban bring a method to the madness.

Back in 1996 I learned how to install software on my spanking new Linux before really understanding the topography of the filesystem. You see, back then, Linux was not the intuitive, user-friendly system it is today. I soon realized I would need to spend some time getting a handle on how the directories were organized and what all their exotic names like etc/ (not a for miscellaneous files), usr/ (not for user files), and bin/ (not a trash can) meant. This tutorial will help you get up to speed faster than I did.

It's not hidden that apart from costing tons of money, the use of proprietary software also brings along hidden security caveats. These are the two primary reasons why the usage of open source software is being pushed in public agencies all around the world, especially in European countries.
