The Linux Journal offers ways to customize Open Office 2.0.

Can't find your favorite functionality tools and shortcuts in 2.0? They still might be available, if you know where to look.

Linux.com brings us the next segment of their Command-Line-Interface series.

Most of us probably use regular expressions -- pattern that describes a set of characters -- every day without realizing it. Chances are, however, that you aren't really using them to their full potential.

The Linux Journal offers help with the popular programming language Ruby.

What's behind all the Ruby hype? Reuven walks us through a couple of examples to let the code speak for itself.

Linux.com demonstrates how to gather information via the command-line in this tutorial.

There are lots of ways the CLI can help you. Often, you don't need to do something so much as you need to know something. This week we'll take a quick look at several commands -- whereis, whatis, df, kernelversion, ifconfig, route, and last -- that can quickly answer questions about your system or configuration. Wipe that GUI mess out of your eyes and meet me at the CLI.

NewsForge offers this tutorial on increasing portability when programming in C and C++.

One of the things I usually take care of as a Gentoo packages maintainer is sending patches to upstream developers. If a patch is applied upstream, we can remove it from future versions of a package so we have less work to do to maintain the package. Unfortunately, it seems that other distributions and packagers don't always do the same. This is true not only for Linux distributions such as Debian, Fedora Core, and SUSE, but also for maintainers of packages in places like FreeBSD's Ports, DarwinPorts or Fink. Here are some tips for developers on making things easier for yourself and everyone who has to touch your code.

Big Blue wants to show you how to setup a wireless ISP with Linux.

Setting up a wireless Internet Service provider (WISP) for your office or neighborhood doesn't have to be a taxing or expensive ordeal. If you build your network from easy-to-buy equipment and use Linux™, you can use the power of shell scripts to make network management easy. This article gives you the tips and scripts you need.

Novell has posted a tutorial created by one of their software engineers on programming in PHP, Perl, Python and Ruby in Linux.

While most developers use popular languages such as C, C++ and Java to create solutions on Linux, others are using somewhat obscure or strange languages to create Linux solutions. This article will look at providing Linux solutions using such programming languages as Python, Perl, PHP, and Ruby.

Linux.com shows how to turn a pirate's chest into a Linux powered computer. Arg!

My girlfriend's ancient HP Pavilion was dead, and she wanted a replacement that was a little different from the standard desktop computer. I showed her a few ATX chassis designs on some Web store sites, then casually mentioned that some people like to make computers out of strange and unusual objects. "Really? Could you make one out of a pirate treasure chest?" she asked. She just happened to have one lying around; I just happened to have a Linux-compatible Mini-ITX VIA EPIA ME6000 motherboard/CPU combo lying around. Here's the story of the pirate chest EPIA project, complete with photos.

The NewsForge presents this tutorial on ngrep.

Constant monitoring and troubleshooting are key to maintaining a network's availability. With ngrep, you can analyze network traffic in a manner similar to that of other network sniffers. However, unlike its brethern, ngrep can match regular expressions within the network packet payloads. By using its advanced string matching capabilities, ngrep can look for packets on specified ports and assist in tracking the usernames and passwords zipping off the network, as well as all Telnet attempts to the server.

We visit Linux.com for this tutorial on Bash history.

This week's CLI Magic -- by Shashank Sharma -- is all about history expansion. The Bourne-Again SHell (bash) has a major user base and the fact that it has incorporated some useful features from the Korn shell (ksh) and C shell (csh) might be one of the reasons. History expansion, for example, was first implemented in csh.

We have written a range of guides highlighting excellent free books for popular programming languages. Check out the following guides: C, C++, C#, Java, JavaScript, CoffeeScript, HTML, Python, Ruby, Perl, Haskell, PHP, Lisp, R, Prolog, Scala, Scheme, and SQL.
