The Perfect Desktop - Part 1: Fedora Core 6

Post date: February 22, 2007, 19:02 Category: Desktop Views: 6420 Comments
Tutorial quote: With the release of Microsoft's new Windows operating system (Vista), more and more people are looking for alternatives to Windows for various reasons. This tutorial is the first of a series of articles where I will show people who are willing to switch to Linux how they can set up a Linux desktop (Fedora Core 6 in this article) that fully replaces their Windows desktop, i.e. that has all software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions, and the best thing is: all software comes free of charge.

Video Surveillance With ZoneMinder On Ubuntu

Post date: September 9, 2007, 00:09 Category: Desktop Views: 7629 Comments
Tutorial quote: ZoneMinder is the top Linux video camera security and surveillance solution. In this document I will cover how to get ZoneMinder up and running on Ubuntu 6.06.1 LTS or Dapper Drake with the recent updates included. The surveillance system I am covering here utilizes 4 Dome CCTV cameras hooked up to a single Kodicom kmc-8800 capture card, in addition I also used infra red LEDs so my cameras could see in the dark (honestly I am abit scared to look). ZoneMinder also does a good job with IP Cameras, unfortunately they are considerably expensive in my part of the world, hence 4 cameras would blow my budget.

Benchmarking BSD and Linux

Post date: June 18, 2005, 22:06 Category: Benchmarks Views: 3641 Comments
Tutorial quote: These benchmarks are the result of my scalable network programming research. My interest in this area is to see how scalable and fast network applications can be on standard PC hardware.

I have done most of my research on Linux 2.4, 2.5 and 2.6 kernels using a home-grown distribution I affectionately call "Leanux". I have experimented with several APIs and methods to try and get the most scalability and performance out of a web server. The ultimate goal, however, is to demonstrate scalability by surviving a Slashdotting.

An Easy Way To Install Gnome Shell

Post date: September 21, 2009, 16:09 Category: Benchmarks Views: 3692 Comments
Tutorial quote: Gnome Shell consists of two big parts: the panel and overlay. The panel part is pretty much obvious - system tray, user name, and clock stuff and the activities button which activates the overlay -, and about the "overlay", well, take a look at this screenshot:


Basically, it allows the user to concentrate on switching to a new activity by opening new applications, documents, or both. It displays all the current user workspaces and open windows and facilitates organizing them.

So far, the Gnome Shell installation was quite time-consuming, so most people didn't try it until now. With time, however, this has changed, and you can install it by running a script. Here is how:
