The primary goal of a backup machine for Postfix is that if the first one fails, mail will be collected by the secondary mail server until the primary mail server is back online. When you build the Backup MX be sure to install all of the necessary applications to scan for viruses and check for SPAM as you do not want to overload the primary machine once it comes online.

Installing and Running Linux on Sony PlayStation 3 (PS3): It is possible to install and run Linux on the Sony PlayStation 3 (PS3) video game console (not-including the PS3 Slim model). In fact, there are plenty of distros that are compatible with the PS3 such as Fedora, Ubuntu, openSUSE, Yellow Dog, and Gentoo. The Linux kernel supports PlayStation 3 since version 2.6.21, that means no patches or hacks are required to install and run a full-featured distro.

A confirmed GNOME superfan takes a new look at KDE 4.4 and likes it. This article isn’t a formal KDE 4.4.x review. I’m looking at it with a discerning eye and a prejudiced viewpoint. I don’t feel compelled to present a purely journalistic “fair and balanced” point-by-point arraignment of KDE. There are plenty of lighthearted reviews and cosmetic critiques of the new interface dawdling about so I dare not add another to the din. Instead, I’m stepping back into KDE from a GNOME user’s viewpoint with a single question in my mind: “Does it work yet?”

I admit it: I'm slightly jealous of Microsoft server administrators. You see, in the Linux world, we have the power to create crazily robust and creative systems, but we're often reinventing the wheel.

The other night my son had a school assignment to interview me about how technology had changed since I was a kid. I began rattling off all of the gadgets and gizmos we take for granted today and realized just how far we've come.

Portable document format is one of the most popular file formats on the web. Of course Adobe is the market leader for PDF. However, there are lot of free alternatives around. Here are some free pdf viewers for ubuntu.

The story first hit in last week on the Slovakian tech site DSL.sk. Since I am not linguistically equipped to follow the Slovakian tech scene, I didn’t hear about the story until it was brought up in English on TechCrunch. The gist of these reports is this: DSL.sk did a test of the “ballot” screen at http://www.browserchoice.eu, used in Microsoft Windows 7 to prompt the user to install a browser. It was a Microsoft concession to the EU, to provide a randomized ballot screen for users to select a browser. However, the DSL.sk test suggested that the ordering of the browsers was far from random.

Following Saturday morning's major earthquake in Chile, aid efforts worldwide are already springing into action. The open source Open Street Map (OSM) project plans to lend its support by calling for volunteers to update its maps of Chile on the basis of the latest satellite images. This will assist orientation and coordination of aid teams in Chile.

Microsoft has a problem: it wants to complain about what it considers Google's anti-competitive behaviour. Unfortunately, all the arguments Microsoft made when it was being targetted for anti-competitive behaviour - that it was simply "successful" and "innovative" - can be used by Google too. So Microsoft finds itself arguing against itself - and looking ridiculous.

A course set up by a Junior High public school in Monza, Northern Italy, involves students who find difficult to focus on theoretical, talk-only lessons by teaching them how to build their own computer and install Ubuntu on it. A few participants went back to Windows after the course, but the majority liked Ubuntu so much to stick to it.

It might sound outlandish but the process has begun. First, this patent deal and next you'll see a big announcement from Amazon and Microsoft for this new device.

Frank struggled to organize his thoughts as he left the fiasco of an “interview” he’d just endured at the hands of CIA agent Carl Cummings.  Time to be logical, he thought, not emotional.  If he didn’t start getting a hold of himself, at this rate he’d find himself in jail. 

Government competition agencies are increasingly focused on Google’s growing power in search and online advertising. The U.S. Federal Trade Commission, the U.S. Department of Justice and the European Commission have all determined that Google is dominant in certain markets, including search advertising. In late 2008 the DOJ was prepared to go to court to block Google’s attempt to partner with its largest search rival, Yahoo!. Last year the DOJ told a federal court that Google’s book search plan is anticompetitive in several respects. (One big problem is that Google would help itself to essentially exclusive rights to tens of millions of books—effectively locking out everyone else.) Last week the DOJ reiterated that view in court, even after Google had an opportunity to address the DOJ’s concerns. This week came news that the European Commission is investigating various aspects of Google’s conduct, including claims of retaliation, exclusivity and manipulation of search results to disadvantage rivals. The European Commission is likely to treat these cases quite seriously, given that Google’s share of search and search advertising is north of 95% in many European countries.

Archbang, like Crunchbang Linux - but Arch and Openbox, is now available for the first time with an installer.

In this article I will describe how you can monitor your Debian Lenny server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

A look at the first ever Gnome Shell themes and how to install (or even create your own) a Gnome Shell theme.
