Post date: January 10, 2006, 12:01 Category: Network Views: 65
Tutorial quote: Most of you have probably heard of Ruby on Rails and may be wondering what exactly it does and how you can try it for yourself. Put simply, Rails is a web application framework that uses the model-view-controller software design pattern to allow for rapid development of web applications. This article will cover how to install Rails on Debian and how to configure it to work with Apache and a relational database of your choice.
RedHat Creating desktop profiles with Sabayon
Post date: July 18, 2005, 18:07 Category: Desktop Views: 101
Tutorial quote: Instead of creating a new desktop setup every single time a new user comes along, it would be much easier to create some templates. If only there were an easy way to make and manage these templates.

Fortunately, we are not the first to ponder this issue. The creators of Sabayon decided to tackle the lack of a good desktop setting management tool. With Sabayon, they created an application that handles these problems and more.
Unix+clones How to create OpenOffice.org macros and automation
Post date: April 12, 2005, 20:04 Category: Software Views: 31
Tutorial quote: There are times when you need to perform some task over and over, or when a task is complex enough that doing it manually makes it hard to get it right. OpenOffice.org macros allow you to save a sequence of operations with a single name so you can do the same thing repeatedly. Automation is a first cousin to macros. It lets another application control OOo and make things happen without user intervention.
Slax Creating a custom live CD with Slax
Post date: June 15, 2005, 12:06 Category: Miscellaneous Views: 238
Tutorial quote: Live CDs can be useful for testing an operating system or performing special operations -- assuming there's a live CD distro that does what you need. Unfortunately, if you are running a special application, especially one you wrote yourself, no live CD will be tailored exactly to your needs. But creating you own live CD is easier than you might think, with Slax and its easy customization utility MySlax Creator.
Linux Today's Linux screen capture technology
Post date: April 12, 2005, 14:04 Category: Miscellaneous Views: 42
Tutorial quote: "I'd like you to help me find out about video screen captures," said one of my editors a while back. "Sure, let me see what's available," I replied. He pointed me to a couple of Web sites to get me started, and here I am a few weeks later ready to share my findings. I'll discuss ways that you can make video clips in Linux, talk about their applications and shortcomings. I'll also cover suitable ways to view your masterpieces once they're recorded.

Video screen captures are useful for jobs like application training, computer instruction, or product demos. An example would be the little one-minute video I set up for my wife. She kept forgetting how to start up Mozilla Mail on her Windows 98 machine. I captured the mouse clicks and screen changes (in real time) as I ran through the process, saving it to a Macromedia Flash file. I then created a little Web page on one of my Apache servers, that described how to start Mozilla Mail and included a link to the Flash file. Instead of asking me how to do it, she can now just click on the video tutorial.
Ubuntu Installing Windows XP/2000 in Free VMWare Player
Post date: November 27, 2005, 12:11 Category: Miscellaneous Views: 216
Tutorial quote: This guide will allow you to install Windows XP or 2000 solely with the VMWare Player. For the uninitiated, VMWare released a free application that allows users to run, but not create virtual machines. Using QEMU, we will create an environment suitable for use with the player.

As a side-note, I'd like to point out that VMWare makes quality software. If you require additional functionality, consider upgrading to Workstation.
Linux Hardening Linux: a 10 step approach to a secure server
Post date: June 22, 2005, 06:06 Category: Security Views: 156
Tutorial quote: The Internet has become a far more dangerous place than it was 20 years ago. Nowadays, Operating System and application security is an integral part of a server configuration and, while firewalls are very important, they are not the panacea.

This list of steps is intended as a guideline with a practical approach. We’ll try to provide a complete picture without getting into unnecesary details. This list won’t replace a good book on secure systems administration, but it will be useful as a quick guide.

Before we get started it’s worth to mention that security is not a status: it’s just a process. The correct initial setup of the server only provides a good start and helps you get half the way through. But you actually need to walk the other half of the road, by providing proper security vigilance, monitoring and updating.
Unix+clones Streaming music with SlimServer
Post date: June 15, 2005, 12:06 Category: Network Views: 72
Tutorial quote: Converting your CD collection into MP3 or another digital file format gives you the ability to enjoy the music on your computer and stream it all over the house and the Internet. To do the latter, however, you have to install and configure a streaming server on your computer. That might sound like a daunting task, but there is a streaming server application that makes the whole process pretty painless. SlimServer from Slim Devices is a cross-platform streaming server that runs on Windows, Linux, and Mac OS X and supports a wide range of formats, including AAC, AIFF, FLAC, Ogg Vorbis, MP3, WAV, and WMA. Although it was developed to stream music files to Slim Devices' Squeezebox2 hardware player, it works perfectly with any software MP3 player capable of working with network streams.

It's a simple application of what you already have learned in our Gimp tutorial series about using the Gimp's layer and pattern tools.
Unix+clones A web server in a shell script
Post date: March 14, 2006, 03:03 Category: Programming Views: 30
Tutorial quote: Suppose you want to experiment a little with web pages and CGI's, but you don't want the hassle of installing the full Apache package. This quick and dirty shell script could just be what you need.

Put simply, a web server is an application that sends local text files over the network to the clients that request them. If you let another program (for example inetd) deal with the network part, the web server could be reduced to a mere cat "$filename" to stdout. Of course, the difficult part would be to extract that filename out of the HTTP request string: nothing that a Bash script cannot easily do!
