Goal of this how-to: Step to step guide on how to setup OpenDKIM with postfix on Debian GNU/Linux to send signed email from your VPS. There are numerous methods or techniques that you can use to achieve email message signing. Good examples are DomainKey as well as DKIM which is an abbreviation for DomainKeys Identified Mail. DomainKeys Identified Mail (DKIM) lets an organization take responsibility for a message that is in transit. The organization is a handler of the message, either as its originator or as an intermediary. Their reputation is the basis for evaluating whether to trust the message for further handling, such as delivery. Technically DKIM provides a method for validating a domain name identity that is associated with a message through cryptographic authentication.

I hope you have enjoyed the first and the second parts of the Linux Screenshot Beauty Contest. Let's see the third part.

Over the course of the past year a case about four financial software patents has taken on great significance. In 2007, Alice Corp accused CLS Bank of infringing its patents on a type of computerized trading platform that used "shadow accounts." In the years since then, the Supreme Court has significantly tightened up the rules about what is patentable. In 2011, Alice's patents were thrown out by a federal judge, who ruled they didn't cover patentable subject matter.

Despite using Linux there is software most of us use every day that is proprietary in nature. In this review of Fedora 18 I ask the question "Can we ever be totally free?"

Are you confused by the recent spate of Java SE updates? You ain't seen nothing yet. While Oracle has diligently been updating Java for security flaws (and some features too) in recent months, it has been hard to keep track of version numbers. Oracle is not introducing new nomenclature that might make it easier or harder, depending on your perspective.

Last week, The White House published an Executive Order by which the default method for government data collection and dissemination must now be open and machine readable.

Social sites are a key part of online life and with Firefox we want to make it easier to use the Web the way you want.  Mozilla developed the Social API to enable social providers to integrate directly into Firefox … Continue reading

NASA’s Linux-based “Robonaut 2? is undergoing extensive testing on the International Space Station (ISS), and will soon be put to work. The humanoid Robonaut 2 will soon receive a major upgrade that will provide legs and an expanded battery pack, enabling it to perform more duties, including space walks. Robonaut 2 arrived at the ISS in Feb. 2011, billed as the first dexterous humanoid robot in space, but it has yet to see much action. Recently, however, the bot has been undergoing extensive testing of its motor controls and vision system.

Barely a week after the big Debian Wheezy release and Google is already making a big move in its direction. The Google Compute Engine (aka Google's Cloud) is moving to Debian. "For fast performance and to reduce bandwidth costs, Google is hosting a Debian package mirror for use by Google Compute Engine Debian instances," Jimmy Kaplowitz, Site Reliability Engineer and Debian developer, wrote in a blog post. "We are continually evaluating other operating systems that we can enable with Compute Engine. However, going forward, Debian will be the default image type for Compute Engine." Google's own Goobuntu distribution which is used on internal desktop's is based on Ubuntu.

One of the exciting features of LLVM 3.3 that is due out next month is the final integration of the AMD R600 GPU LLVM back-end. This LLVM back-end is needed for supporting Gallium3D OpenCL on AMD Radeon graphics hardware, "RadeonSI" HD 7000/8000 series support, and can optionally be used as the Radeon Gallium3D driver's shader compiler. In this article are some benchmarks of the AMD R600 GPU LLVM back-end from LLVM 3.3-rc1 when using several different AMD Radeon HD graphics cards and seeing how the LLVM compiler back-end affects the OpenGL graphics performance.

Vim is always my favorite text editor. I've been using Vim for over 2 years and still learning it. If you want to use Vim, the first thing you will need to know is how to navigate in Vim, since it is text-based.

Back in March and April, when the Java browser plugin was getting hammered with security holes that were being exploited in the wild, we conducted a couple of unscientific polls here on FOSS Force to determine how our visitors were handling this security crisis.

What makes Linux Mint so awesome? That, in itself, is quite a question. After all, why do we use Linux? It's one of those questions that can only be answered from the point of view of an individual's personal approach to their experiences with the operating system itself.

As you might have seen in Jonathan’s blog post we discussed Mir in Kubuntu at the “Mataro Sessions II”. It’s a topic I would have preferred to not have to discuss at all. But the dynamics in the free software world force us to discuss it and obviously our downstream needs to know why we as an upstream do not consider Mir adoption as a valid option.

First-quarter 2013 shipments of “smart mobile devices,” including notebooks, tablets, and smartphones, swelled by 37.4 percent year-on-year to 308.7 million units, reports mobile market analyst Canalys. From the operating system perspective, Android grabbed a healthy majority of units shipped, at 59.5 percent. Of the other leading smart mobile device OS vendors, Apple’s iOS accounted for [...]

Want to run Linux on the Google Computer Engine cloud? Starting immediately, Debian Linux is Google's Linux of choice.

JQooBe is a platform that allows users to create simple blogs, websites, and advanced applications within a community. It is developed in PHP, Ajax, and MySQL. I talked with Federico Pilia, one of the founders of JQooBe, about why this platform is different from other content management systems.

Android looks unstoppable, and it's a mess. The first fact tends to eclipse the second observation, but Android's new supremo diplomatically acknowledges as much in an interview. "Here’s the challenge: without changing the open nature of Android, how do we help improve the whole world’s end-user experience?" Chrome chief Sundar Pichai told Official Google Hagiographer™ Steve Levy.

I like Arch and I like Cinnamon, so for me Cinnarch Linux was an obvious fit. Except for the fact that apparently Cinnamon doesn't work so well with Arch.
