O3 Magazine
O3 magazine is a free magazine distributed electronically in PDF format. O3 is published on a monthly basis. The focus of O3 is on the use of Free and Open Source (FOSS) software in Enterprise Data Networking environments. Some articles in O3 will introduce open source solutions, while some are designed to demonstrate how to integrate open source solutions with leading Enterprise Data Networking hardware from a wide variety of vendors.
O3 is created using Open Source tools exclusively. Scribus, an Open Source Desktop Publishing solution for Linux® is used to layout and produce the PDFs, while The Gimp is used for image creation and manipulation and Open Office is used by our writers to create the articles.
Each issue of O3 magazine features articles on the following topics:
* Security
* Internet
* Web Technologies
* Business
* Voice/Multimedia (VoIP)
* Networking
* Network Applications
* Network Security

Who should read O3?

O3 should also appeal to the small business owner who is interested in a strong, secure and scalable IT infrastructure without incurring high deployment costs.
