Many that play PC games, such as battle.net, need to be able to set up port triggering. Typical "hardware" routers have the ability to set this up from online menus. However, using a Linux PC to perform your router functions can provide much more control and versatility than can be realized with a "hardware" router.

Over new year, I've been playing around with Strigi and Nepomuk, which are the two technologies around desktop search and "making sense of your data". Strigi is the underlying library that is used to analyze all sorts of files and index those results. Nepomuk provides a semantic layer on top of this information, and a nice KDE API for easy integration in applications.

This isn't about a shell script, it's about a really cool technique to apply in shell scripts. Have you ever been worried about multiple instances of a shell script running because they might overwrite or corrupt the data or devices they are working on? Here's a way to prevent that.

Having several offices in the company and one of our policy being to allow people to work from home, a lot of our services are available as web services. As we make heavy usage of virtualization, these websites are spread on many different virtual machines, depending on their requirements (PHP, Java, Python, Mysql, Postgresql...).

During my work with computers, I like to check the usage of system resources in my network. Sometimes a running process takes up too much CPU load, or the disk I/O goes too high. To get a clean picture of how much resources are being used by a client, I used ifstat, top(1) and iostat(1). Since I have found out about dstat, I can cleanly check out all the system resources used by my computers.

While you were likely to be opening up Christmas presents, Linus Torvalds was giving Linux users around the world a special present: the release of the next major Linux kernel: Linux 2.6.28.

There's nothing quite like command-line tools for handling large batches of tasks, and image manipulations are no exception. Web developers and administrators will appreciate the ability to handle large numbers of files easily, either at the command line or in scripts.

In 1976 one man changed the face of text editors. That man is Bill Joy who developed vi for BSD UNIX. To those who are a bit unfamiliar with command line UNIX/Linux, vi (short for Visual) is a screen-oriented text editor that operates in two modes: insert mode and normal mode. Please reference here for a deeper explanation of its design and implementation.
