In part 1, we installed and tested the Postfix SMTP server. Postfix, or any SMTP server, isn't a complete mail server because all it does is move messages between SMTP servers. We need Dovecot to move messages off your Postfix server and into your users' email inboxes.

Everything has a season, and as organizations age—communities, charities, companies, churches and more—they face similar diseases of time. These are emergent patterns of failure that arise not from mistakes but from the consequences of earlier success. In open source, we are seeing the same patterns emerge; this should not be a surprise. read more

At the recent ELC Europe event in Berlin, Bird gave a “Status of Embedded Linux” keynote in which he discussed the good news in areas like GPU support and virtually mapped kernel stacks, as well as the slow progress in boot time, system size, and other areas that might help Linux compete with RTOSes in IoT leaf nodes.

With the recent release of Fedora 25, Fedora 23 will officially enter End Of Life (EOL) status on December 20th, 2016. After December 20th, all packages in the Fedora 23 repositories will no longer receive security, bugfix, or enhancement updates,... Continue Reading →

This tutorial shows how to prepare a Debian 8 (Jessie) server (with nginx, BIND, Dovecot) for the installation of ISPConfig, and how to install ISPConfig 3.1. ISPConfig 3 is a web hosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers nginx (instead of Apache), BIND as DNS server, and Dovecot (instead of Courier).

Animation is a robust field with a large number of specialties and an even larger number of tools for creating a particular look or style. In the past two months, I've covered Krita Animation for hand-drawn digital cel animation and StopGo for stop motion animation. read more

The internet didn't come with privacy, any more than the planet did. But at least the planet had nature, which provided raw materials for the privacy technologies we call clothing and shelter. On the net, we use human nature to make our own raw materials. Those include code, protocols, standards, frameworks and best practices, such as those behind free and open-source software.

Open source continues to drive rapid innovation in the 3D printing industry. This makes sense if you stop and think about it—a 3D printer exists to make other things. Combining that philosophy with free software and open source hardware helps other people participate in improving the objects that it makes, and in making the printers faster, smarter, and cleaner. Here are a few of my favorite open source 3D printing innovations from 2016: read more

In previous years, we have distinguished between open source cloud and others. But as cloud technologies have evolved it’s evident that any cloud without open source would be the equivalent of an automobile without an engine.

The Linux Foundation released its 2017 schedule, including an Embedded Linux Conference in Portland on Feb. 21-23 that needs proposal ideas by Dec. 10. This year, Linux Foundation events attracted over 20,000 “developers, maintainers, sysadmins, thought leaders, business executives and other industry professionals from more than 4,000 organizations across 85 countries,” and 25,000 are expected […]

Over the past few years, interest in both civilian and commercial use of drones has continued to grow rapidly, and drone hardware sits at the top of many people's holiday wish lists. read more

Traditionally, platforms and software stacks were implemented using proprietary software, and consisted of various software building blocks that originated as a result of internal development or via third-party software providers with negotiated licensing terms.

When we think about skills needed to build open structures and establish open mindsets, collaboration jumps to mind immediately. In order to collaborate effectively, communication—or rather, clear communication—is imperative to making it all work. read more

In the previous article, we looked at some of the basics of rsyslog -- a superfast Syslog tool with some powerful features for log processing. Here, I’ll be taking a detailed look at the main config file.

Redmine is an open source web application for project management and issue tracker. In this tutorial, we will install Redmine 3.2 with Nginx as the web server, MySQL as the database server on a CentOS 7 (64 bit) operating system.

Operating systems don't quite date back to the beginning of computing, but they go back far enough. Mainframe customers wrote the first ones in the late 1950s, with operating systems that we'd more clearly recognize as such today—including OS/360 from IBM and Unix from Bell Labs—following over the next couple of decades. An operating system performs a wide variety of useful functions in a system, but it's helpful to think of those as falling into three general categories.

If you're reading this article, odds are good that you're not only familiar with the command line on your computer system, but that you're quite comfortable using it to the exclusion of the graphical interface. I understand—I've been using the command line since that was the only option in the computing world, and even contributed code to BSD Unix, back in the day. There's a lot about modern GUIs that make them superior, but in terms of power, speed, and flexibility, the command line still rocks, and even more so if you can type quickly. read more

Igel has launched a “UD Pocket” USB stick that boots up a VDI environment on any 64-bit x86 PC, laptop, or other device without overwriting its local OS. Since the early days of Linux, IT administrators and demo presenters have been using USB stick and Live CD-based devices to boot up Linux distributions like Knoppix […]

Endless Sky is a 2D space trading and combat game similar to Escape Velocity. The game sets you as a beginning pilot, just having made a down payment on your very first starship. You’re given a choice between a shuttle,... Continue Reading →

So you have a Raspberry Pi, or you’re thinking of getting one, and you want to know how to get started and how to become a master user of one. The Raspberry Pi is a single board computer, meaning that in many ways it's a regular PC, except that everything that makes up the computer is on a single board rather than a traditional PC, which has a motherboard and requires a number of additional daughterboards to make a whole unit. read more
