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>>

August 2013 Issue of Linux Journal: Programming

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>>

Dart: a New Web Programming Experience

JavaScript has had a long-standing monopoly on client-side Web programming. It has a tremendously large user base, and countless libraries have been written in it. Surely it is the perfect language with no flaws at all! Unfortunately, that is simply not the case. more>>

Working with Stdin and Stdout

Previously, I erroneously titled my column as "SIGALRM Timers and Stdin Analysis". It turned out that by the time I'd finished writing it, I had spent a lot of time talking about SIGALRM and how to set up timers to avoid scripts that hang forever, but I never actually got to the topic of stdin analysis. more>>

The Über-Skeleton Challenge

I received an interesting message from Angela Kahealani with a challenge: "Here's what I'd like to see in Work the Shell: a full-blown shell script template. It should comply with all standards applicable to CLI programs. more>>

New Products

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

Scientific Visualization with NCL

Many of my previous articles have looked at software packages that do scientific calculations and generate scientific results. But, columns of numbers are nearly impossible to make sense of—at least, by regular human beings. So what can you do? The answer is visualization. more>>

Extending GlusterFS with Python

Are you a Python programmer who wishes your storage could do more for you? Here's an easy way to add functionality to a real distributed filesystem, in your favorite language. more>>

Python Scripts as a Replacement for Bash Utility Scripts

For Linux users, the command line is a celebrated part of our entire experience. Unlike other popular operating systems, where the command line is a scary proposition for all but the most experienced veterans, in the Linux community, command-line use is encouraged. more>>

Symbolic Math with Python

Many programming languages include libraries to do more complicated math. You can do statistics, numerical analysis or handle big numbers. One topic many programming languages have difficulty with is symbolic math. If you use Python though, you have access to sympy, the symbolic math library. more>>

Calculating Day of the Week, Finally

As with many of the challenges we tackle, the latest project has sprawled across more articles than I ever expected when I first received the query from a reader. The question seems reasonably simple: given a month, day number and day of the week, calculate the most recent year that matches those criteria. more>>
