This document describes how to install a mail server based on Postfix that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses.

Open Source is known for User Interaction with Operating System which cannot be done with other OS
Ladies and Gentleman, the November 2007 Community Report is now available! Go and read it to find out what many of the Ubuntu teams have worked on this month. Rock and roll.
Today I've finished installations of two very different operating systems, Vista and Kubuntu. Both are essentially trying to accomplish the same thing, which is to provide desktop users a satisfying and relatively seemless desktop computing experience. Both succeed to a certain degree and both fail in some important areas. The question is why?
Microsoft DirectX is a collection of application programming interfaces for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms.
Over the past few years, like lots of Linux users, I have become increasingly frustrated with the performance of Firefox in Linux. Though I haven't been as vocal as others of the state of Firefox, it was clear that most of us were just sick and tired of Firefox being a "good Windows browser that happened to run in Linux."
Currently OpenOffice’s presentation program Impress lacks a presentation view with notes and so on for a second monitor during presentations. But the feature is in active development, and first results are visible.
This isn’t about literally searching your install of Ubuntu, this is about searching the Internet for help. For example, if I search Google for Ubuntu games, I get a general mish mash. I get a Digg story on the Top 10 Ubuntu Linux Games. Better yet though, I can use a customized search just for Ubuntu.
Yes, I know the headline sounds like the fodder for a joke: "Run IE on
If you have a fondness for old arcade games and want to play them again, try the Multiple Arcade Machine Emulator (MAME), a free emulator that lets you recreate the look and feel of old arcade game systems in software.

Gogh is an extremely lightweight drawing program designed for pressure-sensitive devices. Despite its simplicity, it packs in a lot of features and a lot of fun.
Ah, the crassness of the commercialized holiday season is upon us, and I could curl my lip and refuse to participate, but no! Instead, I have scoured the Internet for holiday gifts that are geeky with an open source, stick-it-to-the-man slant. Now these are just my random, probably unsuitable selections, but you feel free to add your own ideas.
I found an even easier and more effective way of keeping prying eyes away from my stuff in Ubuntu, and thought I would expand another of my tutorials, "Create an Invisible Desktop Shortcut in Ubuntu". This one is so easy, I'm not even going to use more than one step. Enjoy...
Although Mozilla Corporation has this week released the opening 3.0 beta of its popular Firefox Web browser, it has issued a warning to mainstream Web users that the beta should only be adopted by related software developers and those officially connected to the browser’s testing process.
As my colleague Sam Varghese has written , after nearly two weeks of flawless operation, my first Ubuntu Linux installation unexpectedly became unstable, crashed and was unable to be booted. Puzzled that an OS with the reputed stability of Ubuntu could behave like this, I searched forums and user groups for an explanation. What I found led me to believe that an open source package manager called Automatix that I installed was the cause. As a result, I am going to try an experiment: same computer, two disks, two clean installs, two operating systems - Vista and Ubuntu. But is there an issue with Linux and video codecs?
So there you are. You’re an average geek with a nice cluster of Linux systems. All configured to act together in whatever you’re doing with it.
One of the reoccurring ideas in revisions of the desktop is to tie it more closely to the Internet. The idea was last popular in the late 1990s, when one example of it was the use of KDE's Konqueror for both web browsing and file management. Now, with the GNOME Online Desktop (GOD), the idea has been revived to reflect the rise of social networks and file sharing. The revisions to the standard GNOME desktop are easy to learn, but how you view them will probably depend on how much you participate in the phenomena they're designed to accommodate.
Microsoft's rivalry with Google heated up considerably this past year when rumors surfaced that Google might release its own operating system to compete with Windows. Has Google finally jumped into the fray with its own OS?

This is a detailed description about setting up an Ubuntu based server (Ubuntu 7.10) to act as file- and printserver for Windows(tm) workstations in small workgroups. This howto uses the tdb backend for SAMBA to store passwords and account information. This is suitable for workgroups for up to 250 users and is easier to set up than an LDAP backend.
Mencoder is part of the MPlayer media player package. While MPlayer can play audio and video files, mencoder converts and manages multimedia files.
