This tutorial shows how to install the free VMware Server on an Ubuntu 7.04 (Feisty Fawn) system. With VMware Server you can create and run guest operating systems (virtual machines) such as Linux, Windows, FreeBSD, etc. under a host operating system.
When you're dealing with multiple drives, both fixed and removable, it can get hard to remember which is which. Remembering to mount /dev/sda1 in one place and /dev/sdc5 in another. The solution to this problem is to use labels instead of partition names when referring to them, and here we'll show how that can be done.

Recently I did a lecture on the magical world of vim. Despite having used it for quite a long time I realize there is still far more that I could know about it, but there is also more that I haven’t published on this blog. Some of you might remember some of my earlier posts on vim [here], [here].

Last week, my fellow FOSSwire blogger Jacob introduced you to APT, the powerful package management system that is underneath Ubuntu.
The command line interface is the most powerful way to manipulate the software installed on your system, but to users who aren’t familiar with a command line interface, it can be a bit daunting.
DNS Stands for Domain Name Service.On the Internet, the Domain Name Service (DNS) stores and associates many types of information with domain names; most importantly, it translates domain names (computer hostnames) to IP addresses. It also lists mail exchange servers accepting e-mail for each domain.
I believe that every organization should have a NTP/time server if they have more than one computer on site. Having an NTP server will allow you to keep the times on all of your computers in sync. This helps when comparing the logs from various servers to trace through various events that happened.
The ext3 filesystem is probably the most common filesystem used upon GNU/Linux machines. It isn't necessarily the fastest, the best, or the most modern filesystem but it does perform adequately for the majority of users.
You hear about the great macro feature of Emacs all the time. You see cheat sheets for Emacs key combinations all the time. But you never quite see the keyboard macro trick demonstrated clearly. Here's how it works:
