About this site

Introduction

Unixrealm was created in 1999. It was designed to be a source of information, mainly for systems administrators and other people who have to deal with computers on a daily basis.

The idea came from my own frustration of constantly looking for information on twenty different search engines. I basically created this site using my own Netscape bookmarks hoping visitors would submit links and help make this site bigger and better. Every submission will be carefully checked to make sure they satisfies unixrealm.com's requirements. My goal is not to have millions of links but a handfull of usefull links (the good old quantity vs. quality thing...).

Server

unixrealm.com runs on an Intel machine running the RedHat distribution of Linux and the Apache web server. The apache is configured to allow me the use of Server Side includes. These days, a lot of the old server side includes have been replaced by php. scripts.

About Myself

Well, I am the one who put this site together originally and I am currently the one who maintains it. This site is just starting so it is pretty low maintenance. I wanted to write a little something about myself in here. Since I did not have the time, I included my resume as a starter. I am not currently seeking employement.
