Your GNU/Linux computer is an amazing machine. It can display images. It can run programs. It can perform dozens of functions all at the same time. How can you keep track of all this activity? By monitoring the processes that your computer runs, and one of the best ways to monitor and control processes is by using the command line.

WordPress Complete is a guide to “set up, customize, and market your blog using WordPress”. A beginner’s guide, but much more. Interestingly, its author studied in Bangladesh, and it is published by a firm that straddles Birmingham and Mumbai!
GNU/Linux is getting bigger and bigger. Microsoft’s recent patent threats are definitely helping GNU/Linux to gain mainstream popularity. Unfortunately, new users are often confused by why they should actually use GNU/Linux, and how to go about the transition. Hopefully, this article will fill that gap!
Why should everybody use GNU/Linux?
When you are looking for a workstation or new desktop there are a seemingly infinite number of potential solutions available. So where do you start? Well if you are after a powerful AMD based computer then you might want to take a look at the Sun Ultra 20 M2, a workstation based around AMD Opteron 1200 dual-core CPU, and available at a surprisingly reasonable price.
Workstation or desktop?
The desktop computer is not dead, but it’s doomed. Laptops are not dead, but they are doomed. And our mobile phones are going to kill them... sounds unlikely? Well, please read on—and let me know what you think. People have predicted the death of the desktop computer and the death of the laptop many times. These death sentences have often sounded like those religions which predicted the world would end by the year 2000—then the year 2000 came, and the end of the world was then rescheduled for 2004—then 2004 happily came and went—and so on.
When we enter the world of “free and open source software”, most of us will choose one or the other philosophy. This choice is usually made easy by the people that guide us when we enter this world. We are at a point where the philosophies behind free software, which have been heralded by Richard M. Stallman and others, are threatened; as more people make the jump away from proprietary operating systems, less of them know about these philosophies. Fewer people will weigh the decision for themselves.
What is the difference?
I picked up Beginning Ubuntu Linux, Second Edition with a sense of familiarity; I also had the pleasure of reviewing the First Edition and found the experience to be a gentle and very complete introduction to Ubuntu. It’s as though Keir Thomas wants to ensure that anyone starting out with GNU/Linux won’t feel like a worthless newb being thrown to the proverbial geeks, who will guffaw and point and weeze asthmatically and incomprehensibly.
No one would argue that software auditing is not an important feature of mission critical applications. If a software based process is critical to the life of your company, then so is the security and access control surrounding resources managed by that software based process. Auditing is the way you track who did what to what and when it happened. Lately, however, the software industry has been lackadaisical at best regarding auditing. Off the shelf software developers either care about auditing, or they don’t.
Dedicated to UNIX system managers, the book covers all there is to know about Samba (as of version 3.0.22), how it relates to Microsoft’s Active Directory networking (shares, accounts, printing) and to UNIX’s networking.
Samba itself started in 1991 as a reimplementation of SMB by Andrew Tridgell. The project is under the GNU GPL and now allows any POSIX system out there to behave as a Windows machine in pretty much any role it would play on a network: from Active Directory domain controller to simple client, with all kinds of shares: per user, per group, files, printers...
This article provides a real world perspective into why businesses move to and stick with free software. In this interview, Rob Fraser, from the premiere New Zealand open solutions company Egressive Limited (egressive.com), shares insights into why free software can benefit any business. The interview briefly covers: VPNs, spam filtration and risk mitigation, among other topics.
Free software is great, so why not run it on a free PC? Here’s how to get a free PC and configure it with free software to perform many tasks as well as a newly-purchased computer.
Sniffing out a PC
In this fast and over active world of computers, there is only one thing that seems to remain slow and underrated. I see it at school, with my fellow students; I see it with my friends. At home, I spot the same thing with my mom, and my dad and even my younger brother. It is the keyboard! In this article you will learn how to use TypeFaster to yes type faster!
MINIX, as originated by Andy Tanenbaum, is an operating system that has its roots and heart in academia as a tool that teaches you how kernels really should work. Recently, however, with the advent of version three of this rock solid OS, the focus is on making a production ripe embedded distribution. Being POSIX compatible with a Kernel of 3800 lines of code and a unique approach to handling drivers, MINIX 3 is well worth the effort to review for readiness.
A very brief history
My family is hooked on Windows. I’ve thought about trying to coerce them into switching to GNU/Linux, but the very thought of what I’d have to put up with for the next year just makes my head ache. I’m not talking about software maintenance issues. I’m talking about trying to defend my position time and time again as they complain that they can’t run their favorite games or applications. Telling them to change their favorites is like spitting into the wind—it’s sort of masochistic.
I recently started a new podcast where people like you and me have the chance to put questions to key people in our community. While doing that I discovered some aspects of our community that I feel are often over looked in the drive to find new users.
Why I did it
Did you know that it’s possible to build an entire telephony system centered around computers? One which is free of licensing costs too? Asterisk is a free software application written to do just that, and much more. Why? For the uninitiated, here’s why...
Wherever you go, your free software PBX follows!
When my DVD player stopped working, I definitively proved to myself (and to people I know) that if there is a simple and effective solution to a problem and a complex one which promises unpredictable results, I always choose the second option. Instead of buying a new DVD/DivX/MP3 player for the modest price of $40-50, I decided to build a home-made device that would allow me to record the TV, receive podcasts, watch my favorite movies, view webtv, play games, and a lot of other things that I considered cool. So my modest adventure with Freevo, GNU/Linux and a lot other free software begins...

When I was 14, I bought my first computer magazine. Yes, I was a late starter! What I found amazing was that, after buying my first issue, I understood pretty none of what I had read. There were terms like CPU, RAM, protected mode, driver... I had simply no idea. I was partially excused: we are talking almost 20 years ago, and back then many of those terms weren't as popular as they are now.
The picturesque village of Yankeetown on Florida’s Nature Coast has been the recent target of a large time-sharing resort condominium development proposal. Several townsfolk looked into the development and discovered what appeared to be corrupt practices in the town government. A loosely organized group of citizens decided to coordinate and share information via a web presence. Beyond any expectations, the picture albums, message boards, and mailing lists they used have been the catalyst for gaining state-wide attention and have led to direct intervention from the Governor’s office.
In the last article we parted ways after configuring a base FreeBSD system, enabling it with upgrades via
portsupgrade, and securing it with a simple
ipfw2 firewall. The previous article created a solid foundation which this article will build on, covering the configuration of Postfix, amavisd-new, ClamAV, SpamAssassin, MySQL and finally SquirrelMail for web mail.
