This tutorial will discuss how to set up a working mail server in Ubuntu or Debian. As we know, the two major protocols used in a mail server are SMTP and POP/IMAP. In this tutorial, postfix will be used for SMTP, while dovecot will be used for POP/IMAP. Both are open source, stable and highly customizable.

Today in Open Source: Is the iPhone losing ground to large screen Android phones? Plus: Build an open source laptop, and six Linux distros for netbooks.

Easily benchmark your network connection between Linux boxes by using the netcat tool - you'll get reliable results in just a few seconds.

The acid test was not how much we liked it but on whether our Reglue Kids liked it. Working with a small sampling of 14 installations and different partition boot options, we gauged how well our KDE version did when compared against GNOME 3/GNOME Shell and Cinnamon. Each one of the 14 kids were asked to use all three environments and give us some feedback.

A few days before the announcement for the end of life of Ubuntu 13.04 (Raring Ringtail), Canonical has released the last major update of its soon to be unsupported Ubuntu operating system, fixing no more than nine vulnerabilities discovered by various developers in the upstream kernel packages.

The Intense PC forms the basis for a MintBox2 computer, jointly offered with the Linux Mint project, and it’s also available directly from CompuLab in a variety of customizable models. The Intense PC2 moves up from Intel’s 3rd Generation “Ivy Bridge” Core processors to the 4th Gen “Haswell”. The high-end model offers a quad-core Intel Core i7-4600U, clocked at 2.1GHz, with turbo mode reaching up to 3.30GHz. Other “Haswell” options are also available, including Core i5 and i3 chips, and the Intel Celeron 2955.

Last year, Lauren Egts designed and programmed a game (The Great Guinea Pig Escape) using a youth-focused programming language called Scratch. She presented it at the 2013 Cleveland Mini Maker Faire where it caught the eye of Element14's David Hamblin. He was impressed, and in June, Opensource.com shared Lauren's interview with David about how she got started programming and what her dad, Dave Egts, thinks of her hobby.

Lauri Kasanen wrote into Phoronix to request help in gathering information on the r600g open source AMD graphics driver.

This article proposes a new way to construct Linux and Windows images for private clouds built with the OpenStack cloud operating system. Current image-creation methods for OpenStack environments are cumbersome and time-consuming. The authors present an online, self-service method that makes image construction faster and easier for operators and end users of private clouds.

The first Europe Code Week was held two months ago at schools and CoderDojos in 26 countries around Europe—Ireland and Croatia being the most active. The event was launched to help increase the knowledge shared with school-age children about coding, computer science, and technology by The Young Advisors (a group of young people dedicated to advancing a digital society working closely with the Vice President of the European Commission, Neelie Kroes). During the events, kids from schools all over Europe used Scratch, Arduino boards, and other open source software and hardware to build thier projects (including robots)!   Each country that took part in Europe Code Week appointed an Ambassador to lead their event. I reached out to Ireland’s Julie Cullen, a teacher at St. Oliver’s College, Drogheda, Co. Louth, to get her take on the event. In this interview, Julie shares just how excited the kids were to work with code and computers, what open source software they hacked on, and what projects got underway. She also tells us what’s in store for this year’s #codeEU 2014.

LinuxSecurity.com: My expectations were low when I asked the National Security Agency to cooperate with my story on the impact of Edward Snowden's leaks on the tech industry. During the 1990s, I had been working on a book, Crypto, which dove deep into cryptography policy, and it took me years - years! - to get an interview with an employee crucial to my narrative.

3089 is a futuristic, procedurally generated, open-world action role-playing game. All terrain, enemies, weapons, items, quests & more are uniquely generated. It's also very weird.

Version 9.0.11 of ocPortal, a free and open-source CMS, has been released. This version is a patch release that introduces a number of bug fixes listed in the article.

In mid-November, the open source/open standards advocacy group, Open Forum Europe (OFE), released an "Open Cloud Declaration," which identifies ten principles to help policy makers, industry, and other stakeholders find "a global and open approach to Cloud technologies and solutions." It is not a coincidence, of course, that the Open Cloud Declaration was released during the same week that officials from the European Commission were meeting at a summit in Berlin to discuss data protection and cloud computing policy. These leaders (as well as policy makers in other countries, such as Brazil) are weighing their reactions in response to the ongoing revelations regarding data collection by the U.S. National Security Administration (NSA).

Every year or two, I like to look back over my client’s SSH configuration file and assess what I’ve changed. This year’s emphasis has been on a few options that center around session persistence. I’ve been spending a lot of time on the road this year, using SSH to log into remote servers over terrible hotel wireless networks. As a result, I’ve found myself plagued by SSH session resets. This can be somewhat distracting when I’m in the midst of a task that requires deep concentration— or in the middle of editing a configuration file without the use of screen or tmux.

NVIDIA's latest release series is the 331.xx series (soon to hopefully be replaced by a newer version) while NVIDIA continues maintaining the 319 series as a long-lived branch. NVIDIA has put out 319.82 to provide new GPU support and X.Org Server 1.15 compatibility, the new xorg-server that was released one month ago and will begin appearing in new Linux distributions.
