Girls and Software

December 2013's EOF, titled "Mars Needs Women", visited an interesting fact: that the male/female ratio among Linux Journal readers, and Linux kernel developers, is so lopsided (male high, female low) that graphing it would produce a near-vertical line. more>>

2013 Book Roundup

I'm always amazed to hear about the death of the publishing industry. True, books and (gulp) magazines are often fighting for their lives, and the state of journalism is in tatters. more>>

Compojure

In my last article, I started discussing Compojure, a Web framework written in the Clojure language. Clojure already has generated a great deal of excitement among software developers, in that it combines the beauty and expressive elegance of Lisp with the efficiency and ubiquity of the Java Virtual Machine (JVM). more>>

Web Administration Scripts

During the past month or so, I've also been dealing with an aggressive DDOS (that's a "distributed denial of service") attack on my server, one that's been a huge pain, as you might expect. What's odd is that with multiple domains on the same server, it's one of my less-popular sites that seems to have been the target of the attacks. more>>

Cribbage: Calculating Hand Value

The last few months, we've been building a complex shell script to play elements of the game of Cribbage, demonstrating a variety of concepts and techniques as we proceed. That's all good, and last month, the script expanded to include a "shuffle" capability and the ability to deal out six cards, a typical two-player starting hand. more>>

GNU Awk 4.1: Teaching an Old Bird Some New Tricks, Part II

In an earlier article ("GNU Awk 4.0: Teaching an Old Bird Some New Tricks", published in the September 2011 issue of Linux Journal), I gave a brief history of awk and gawk and provided a high-level overview of the many new features in gawk 4.0. more>>

Sublime Text: One Editor to Rule Them All?

Sublime Text is a proprietary, cross-platform text editor designed for people who spend huge amounts of time shuffling code around. A programmer's editor, Sublime Text is a third option to the long-standing "Vi or Emacs" conundrum. Going beyond the basics of syntax highlighting and code folding, Sublime offers a litany of innovative and unique features. more>>

Get More Juice out of Your Enterprise Code Base with Code Search

When most people think about a company's reusable assets, source code doesn't usually show up on the list, even though millions of dollars are spent every year on creating and maintaining code. Most large companies are managing hundreds of millions of lines of code—the majority of which was purpose-built to solve a specific application problem. more>>

September 2013 Issue of Linux Journal: HOW-TOs

How'd Ya Do That?

I tend to read science fiction or fantasy for entertainment and/or escape from reality. more>>

Sidekiq

From my perspective, one of the best parts of being a Web developer is the instant gratification. You write some code, and within minutes, it can be used by people around the world, all accessing your server via a Web browser. more>>

Advanced OpenMP

Because the August issue's theme is programming, I thought I should cover some of the more-advanced features available in OpenMP. more>>

Building a Better Mouse (and Keyboard) Trap

I've mentioned in years past that my programming skills started with Pascal and ended with bubble sorting. more>>

Developing Your Own Scientific Python Code

In many cases, scientific research takes you into totally new areas of knowledge, never before explored by others. This means the computational work you need to do may be totally new as well. Although typically such code development still happens in C or FORTRAN, Python is growing in popularity. This is especially true in physics. more>>

Pythonic Parsing Programs

Creed of Python Developers

Pythonistas are eager to extol the lovely virtues of our language. Most beginning Python programmers are invited to run import this from the interpreter right after the canonical hello world. One of the favorite quips from running that command is: more>>
