More L337 Translations

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.

Multiprocessing in Python

Python's "multiprocessing" module feels like threads, but actually launches processes. Many people, when they start to work with Python, are excited to hear that the language supports threading. And, as I've discussed in previous articles, Python does indeed support native-level threads with an easy-to-use and convenient interface.

Tackling L33t-Speak

How to script a l33t-speak translator. My daughter and I were bantering with each other via text message this morning as we often do, and I dropped into a sort of mock "leet speak". She wasn't impressed, but it got me thinking about formulaic substitutions in language and how they represent interesting programming challenges.

Weekend Reading: Raspberry Pi Projects

The Raspberry Pi has been very popular among hobbyists and educators ever since its launch in 2011. It’s a credit-card-sized single-board computer with a Broadcom BCM 2835 SoC, 256MB to 512MB of RAM, USB ports, GPIO pins, Ethernet, HDMI out, camera header and an SD card slot. The most attractive aspects of the Raspberry Pi are its low cost of $35 and large user community following.

Getting Started with ncurses

How to use curses to draw to the terminal screen. While graphical user interfaces are very cool, not every program needs to run with a point-and-click interface. For example, the venerable vi editor ran in plain-text terminals long before the first GUI.

Ansible: the Automation Framework That Thinks Like a Sysadmin

I've written about and trained folks on various DevOps tools through the years, and although they're awesome, it's obvious that most of them are designed from the mind of a developer. There's nothing wrong with that, because approaching configuration management programmatically is the whole point.
