Using Gmail as GNOME’s default mailer

Post date: May 17, 2006, 15:05 Category: Desktop Views: 3683 Comments
Tutorial quote: I started using Gmail as my primary mail application a little over a year ago. For the most part, it has been a pleasurable experience. However, to my knowledge there has not been a simple way to make Gmail your default mailer in GNOME. There are firefox extensions that implement this functionality, but I used epiphany and the functionality does not extend to the entire GNOME desktop.

The perfect Setup - White Box Linux

Post date: April 15, 2005, 23:04 Category: Installing Views: 7298 Comments
Tutorial quote: This is a detailed description about the steps to be taken to setup a Linux server based on White Box Linux that offers all services needed by ISPs and hosters (web server (SSL-capable), mail server (with SMTP-AUTH and TLS!), DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.).

Since White Box Linux is very similar to Red Hat Enterprise Linux this tutorial should also work for Red Hat Enterprise Linux.

OpenOffice Tips: Writer, Calc and Impress

Post date: April 14, 2005, 13:04 Category: Software Views: 3296 Comments
Tutorial quote: Making the switch from Microsoft Office to OpenOffice can save you a lot of money on licensing fees, and it isn't difficult--most people get used to the changes quickly. But if you've been using MS Office for the best part of a decade and learned a few of its tricks along the way, you may find yourself baffled about how to do certain tasks in OpenOffice. Here are a few tips on using Writer, Calc and Impress.

Introduction to Python

Post date: April 17, 2005, 09:04 Category: Programming Views: 3692 Comments
Tutorial quote: Ok, first part is going to be fairly boring, but put up with it. Im just going to go through a few reasons why you should choose Python as a language to learn. First off it free!, there is no cost involved in gettin Python, although there is a license, but this is just a standard license that goes with all free and open source software. Python is an open source language, as is the interpreter (Python is written in C).

Arcane Linux Commands: dc

Post date: December 31, 2007, 01:12 Category: Miscellaneous Views: 4349 Comments
Tutorial quote: If anybody within earshot of you is struggling to learn sed and ever remarks "This is like learning Klingon! Could they make it any more cryptic?", you can always point them to dc.

dc is the command-line Unix "Reverse-Polish Notation"(RPN) calculator. The name stands for "desktop calculator". OK, so what is a Polish calculator and why would you want to reverse one? The math that you do in school uses infix notation, with the operator between the numbers (3 + 5). Prefix notation puts the operator first (+ 3 5) and is what the Lisp language uses. The prefix notation is known as "Polish notation" after the nationality of Jan Łukasiewicz who invented it. Postfix notation, then, has the operator at the rear (3 5 +), and so is also the reverse of Polish notation.

What's the difference? In computer programming, you have to specify what order you want a multi-part calculation to be in. Everybody is familiar with the old problem of A*B-C. For A=5, B=3, C=2, multiplying first and subtracting second gives you 13, while subtracting first and multiplying second gives you 5. To specify which operations you want performed first, you have to either memorize the complex orders of operations (which change from one language to the next) or use a lot of parenthesis ((A*B)-C) or (A*(B-C)). Hey, that's what everybody complains about in all those languages that use parenthesis!

Benchmarking Filesystems Part II

Post date: January 6, 2006, 22:01 Category: Benchmarks Views: 5538 Comments
Tutorial quote: After the last article was published, I have received more than a dozen requests for a second filesystem benchmark using the 2.6 kernel. Since that time, I have converted entirely to XFS for every Linux machine I use, so I may be a bit bias regarding the XFS filesystem. I tried to keep the hardware roughly the same. Instead of a Western Digital 250GB and Promise ATA/100 controller, I am now am using a Seagate 400GB and Maxtor ATA/133 Promise controller. The physical machine remains the same, there is an additional 664MB of swap and I am now running Debian Etch. In the previous article, I was running Slackware 9.1 with custom compiled filesystem utilities. I've added a small section in the beginning that shows the filesystem creation and mount time, I've also added a graph showing these new benchmarks. After the first round of benchmarks, I received a sleuth of e-mails asking for the raw numbers. The numbers are now included in tables at the end of this e-mail for both the last and current set of benchmarks.

Configuring virtual domains with Cyrus+Postfix in FreeBSD 5.4

Post date: December 1, 2005, 03:12 Category: Software Views: 5410 Comments
Tutorial quote: Cyrus IMAP is an efficient IMAP server capable of handling a large number of accounts. Its biggest drawback is getting it installed and configured. This tutorial is a step-by-step guide on how to use Cyrus with the Postfix mail transfer agent (MTA). I tested these instructions with FreeBSD 5.4.

Postfix is a replacement for sendmail, the stock MTA that comes in FreeBSD. It is easier to configure and manage than sendmail. If you depend on sendmail, you can still look at the article for the Cyrus part, but you'll need to look elsewhere for the MTA configuration.

Unless otherwise instructed, perform all operations in this tutorial as root. You will need to use the port system. If you are new to it, check Chapter 4 of the FreeBSD Handbook.

An Easy Way To Install Gnome Shell

Post date: September 21, 2009, 16:09 Category: Benchmarks Views: 4870 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:

Linux stateful firewall design

Post date: April 12, 2005, 17:04 Category: Network Views: 3089 Comments
Tutorial quote: This tutorial shows you how to use netfilter to set up a powerful Linux stateful firewall. All you need is an existing Linux system that's currently using a Linux 2.4.x or 2.6.x kernel. A laptop, workstation, router or server with at a Linux 2.4.x or 2.6.x kernel will do. You should be reasonably familiar with standard network terminology like IP addresses, source and destination port numbers, TCP, UDP and ICMP, etc. By the end of the tutorial, you'll understand how Linux stateful firewalls are put together and you'll have several example configurations to use in your own projects.
