By the end of part 1, we had purchased a domain name, set up a basic server, and done a bare-bones installation of Postfix and Dovecot. Here in part 2, we've got three primary tasks: Acquire and install an SSL/TLS certificate for our mail server; Perform some basic Postfix configuration so that it can function as an MTA and work with Dovecot; Perform some basic Dovecot configuration, including setting up three virtual users and their mail directories. Let's get started.

Mozilla quietly announced in a blog post March 7 that it is no longer putting full-time developers to work on the Persona Web-authentication system. In my opinion, that's a real shame and a tragic failure for Mozilla and its efforts to help build a more open and secure Internet.

The first Arduino-certified product to come out of Intel’s embedded systems division, is the Galileo a sign of things to come or a white elephant?

Regrets? None at all, says whistleblower Video NSA whistleblower Edward Snowden, addressing the SXSW conference via video link today, urged programmers to help save the world from government spies who are "setting fire to the future of the internet." developers to help save America.…

When I started teaching PostgreSQL education courses in 2001, PostgreSQL was the ugly one in the data center. Many of the people who were learning how to work with it were doing so grudgingly because of some specific requirement. They had inherited a PostgreSQL database, for example. As a result, many of them tried to learn just enough to do what they needed to do. The other population of students were serious technologists, die-hard open source devotees who wanted to use only open source solutions and were learning PostgreSQL because they needed a relational database for their operations.

Experts team up with space miners to sponsor asteroid finding algorithm contest NASA is teaming up with the asteroid-mining wannabes at Planetary Resources to offer $35,000 in prizes in a contest to develop algorithms to detect Near-Earth Objects (NEOs) – asteroids – with the goal of spotting those that might threaten the Earth.…

Advanced Format disks use 4,096-byte sectors rather than the more common 512-byte sectors. This change is masked by firmware that breaks the 4,096-byte physical sectors into 512-byte logical sectors for the benefit of the operating system, but the use of larger physical sectors has implications for disk layout and system performance. This article examines these implications, including benchmark tests illustrating the likely real-world effects on some common Linux file systems. As Advanced Format disks have become the norm, understanding how to cope with these disks is a vital skill for anyone who wants to avoid serious performance penalties associated with suboptimal configuration.

It’s been a while since I started to talk to people in the financial services ecosystem about our approach towards open source. At first, most of them thinking we were either bold, ahead of our time, or mad would listen to our story but would not really comment: "Let’s see where it goes" or "good luck with your brave intentions." Only after we started to show progress with the delivery of the FinTP Project, did people start to look seriously at what we were doing. That's when FinTP started to stir up interest and we got many inquiries about the project. I’ve already shared the most common questions, like: Why do we do it? Why should we join?

Google is beefing up its Compute Engine offering to go head-to-head against Amazon Web Services. The company is adding autoscaling and reserved instances to its infrastructure-as-a-service (IaaS) offering.

At South by South West this morning, Box CEO Aaron Levie predicted a future in which the generic Box app, which is the most popular use of the service now, would take a back seat to custom apps built on top of the Box platform to meet the needs of specific verticals and individual services.

AntiSquad is a fun looking turn based strategy game with character development included at no extra cost, bargain! The developer has confirmed it will come to Linux.

A survey conducted by PerspecSys at RSA Conference shows that the security of cloud is still a top priority and a top concern among IT security professionals.

If you're curious how Ubuntu 14.04 LTS is running against upstream Debian, given that SteamOS is Debian-based and Gabe Newell runs Debian, here's some fresh benchmarks comparing several flavors of Debian against Ubuntu 14.04 in its current development state.

Seco has spun a pair of nearly identical Qseven COMs, based on Intel Atom E3800 and AMD G-Series SoCs, and featuring extended temperature and optional SSDs.

The ASUS Zenbook UX301LA-DH71T is a Haswell-based Intel ultrabook that I have found to be quite interesting and will be carrying out a large number of Linux tests (and Windows 8.1 vs. Linux benchmarks) from this laptop that sports Intel Iris Graphics 5100, dual SSDs, and other impressive features.

TinyKeep is an upcoming action RPG with a heavy focus on smart monster AI. We all hate dumb AI in games right? I hope their AI is as smart as they make it out to be!

The secret Foreign Intelligence Surveillance Court has ruled against a U.S. government request that it be allowed to hold telephone metadata beyond the current five-year limit as it may be required as evidence in civil lawsuits that question the data collection.

“Why we don’t all switch to Diaspora I will never understand.”

My friend Ross made this remark on Facebook Thursday as introduction to a link to a petition by Demand Progress, a progressive political action site. The petition addresses Facebook and privacy issues, making some rather disturbing accusations. Although the text is short on siting sources, the accusations still ring true. The claim is that every time something is typed into a comment box but then not posted, Facebook keeps a record.

In today's open source roundup: Lubuntu could be the best replacement for Windows XP. Plus: A review of Portal 2 for Linux, and an interview with the creator of educational distro Ubermix.

Indeed, ever since Snowden provided reporters with a trove of top secret documents, we've been subjected to all sorts of NSA word games. And the word "collect" has a very special definition, according to the Department of Defense (DoD). A 1982 procedures manual says: "information shall be considered as 'collected' only when it has been received for use by an employee of a DoD intelligence component in the course of his official duties." And "data acquired by electronic means is 'collected' only when it has been processed into intelligible form."

Aimed at the complete novice, this is an overview describing in some detail the reasons I use Linux.

What's new for Google's Summer of Code (GSoC) internship program this year? For one, GSoC accepted 190 mentoring organizations, which is more than any other year. The very first GSoC program began in the summer of 2005, so this year also marks another milestone—they're 10th year anniversary. What is likely to remain the same this year is the overwhelming response from students from all over the world who want the chance to work on free and open source projects with mentoring organizations that Google has hand-picked.

In the world of mail servers, MailScanner is one of the best open source software for virus scanning and spam detection. MailScanner relies on pre-installed anti-virus and anti-spam software to check incoming and outgoing emails for malicious content or patterns of spamming. This makes sure that the mail server does not participate in the distribution of malware and unsolicited spam emails. It also helps preventing the mail server IP from becoming blacklisted, keeping the mail server records clean. This tutorial will focus on setting up MailScanner along with Clam Antivirus and SpamAssassin in a CentOS system. The procedure should work on RHEL as well.

Consistency—a necessity when it comes to any large-scale, open source project. Sharing source code and libraries between the different components of OpenStack is critical to its rapid evolution and fast-paced development. The Oslo program is what holds it all together and brings consistency to OpenStack. We wanted to learn more about Oslo and what is does for OpenStack. So we asked the program lead to share his thoughts.

MakuluLinux was already a solidly performing distro, but the latest version, released last month, takes Makulu to the next level of usability and maturity. Earlier versions offered a choice of Xfce, KDE and Enlightenment 17 desktops. So far, only the Xfce version is available in MakuluLinux 5. However, the tweaking Makulu developer Jacque Raymer built into this upgrade makes up for any loss.
