In Linux and UNIX system services are configured using various text files located in /etc/ or /usr/local/etc/ directory tree. A typical server system could have dozens of configuration files.You can check your configuration files for syntax errors without starting the server and validate all settings.

I haven’t had to use MS-Office / word in years and I have never had a problem with awesome OpenOffice.org software. I have been using it in Linux for a long time, and recently at work we started using it in windows-xp systems too. I have also got a couple other people in my school, work and small business to use it as well. This tutorial explains the approach you take when you want to print labels under Ubuntu Linux using gLabels. It is a label, business and media cover designer for the GNOME. The intuitive editor allows to create text fields, insert images, simple objects, and create barcodes. It is designed to work with common laser/inkjet printers peel-off label and business card sheets. From the article:
Ubuntu has no shortages of software for printing labels. Many users content themselves with the label and mail merge features in OpenOffice.org Writer or in Abiword or KOffice. All these solutions will do a basic job, especially with text. But what if you want elaborate formatting or graphics with your labels? What if you want a smaller, dedicated program that is quicker to load than a complete word processor? In these cases, you should consider turning to gLabels instead.
Canonical the makers of Ubuntu about to introduce a new desktop notification system proposal. New changes should improve the usability of the Linux desktop including desktop notification system for both GNOME and KDE. From the Mark Shuttleworth blog:
The key proposals we are making are that:
* There should be no actions on notifications.
* Notifications should not be displayed synchronously, but may be queued. Our implementation of the notification display daemon will display only one notification at a time, others may do it differently.
That’s pretty much it. There are some subtleties and variations, but these are the key changes we are proposing, and which we will explore in a netbook device with a partner, as well as in the general Ubuntu 9.04 release, schedule gods being willing.
I think new changes looks more like Growl system used in Mac OS X. You can read more about proposal including mockup video that shows new notification system here.
