At ELCE, Neopenda’s Teresa Cauvel explained how her team built a low-cost neonatal wearable for developing countries using an Intel Curie running Zephyr. The Zephyr Project is still a babe in the technological woods, so it’s only fitting that the open source real-time operating system is driving an innovative wearable solution that aims to improve […]

In OwnCloud, we can add external storage as ownCloud storage devices to extend the storage capabilities of the local server. In this tutorial, I will show you how to enable an external storage or drive in ownCloud 9.

For many of us 2016 flew by, and we didn't complete all our New Year's resolutions or mark everything off our "2016 To Do" lists. I didn't have nearly enough time to play with the Raspberry Pi this year, and my list of projects I want to do keeps growing. In this article I've rounded up 8 recent Raspberry Pi projects that I haven't made yet, but that made it onto my "2017 To Do" list. read more

We surround ourselves with our own personal soundtrack. Our music reminds us of the most significant times in our lives and helps us shape how we feel and view ourselves. Having a music player that supports the freedom to choose how our music is delivered to us while not detracting from the playback quality is important, and I've been carefully evaluating open source music players for quite some time. read more

Aaeon’s rugged, Linux-ready “Boxer-6616” embedded controller ships with “Apollo Lake” Celeron or Pentium SoCs, and offers 6x serial and 4x USB 3.0 ports. Aaeon’s Boxer-6616 follows in the steps of the Intel “Bay Trail” Celeron based Boxer-6614. This time, Aaeon moves up to either a dual-core Intel Celeron N3550 or a quad-core Pentium N4200 of […]

There are many recent examples of the threats to Internet security. We’ve talked about how protecting cybersecurity is a shared responsibility and we see increased need for governments, tech companies and users to work together on topics like encryption, security … Read more

It's getting down to the wire here for the holidays. You know, that time when we all realize that we've completely neglected to get gifts for people. While reading through our very excellent gift guide, a thought occurred to me: Those unfortunate souls with lives devoid of technological wonder... they need presents, too. 

In a previous article, I introduced the Tiny Internet Project, a self-contained Linux project that shows you how to build key pieces of the internet on a single computer using virtualization software, a router and free open-source applications.

At some point in your Linux administration career, you are going to edit a configuration file, write a Bash script, code, take a note, or any given task associated with text editors. When you do, you will turn to one of the popular text editors available to the Linux platform.

A few years ago, I gave a lightning talk at Red Hat Summit that took attendees on a tour of the 2012 open source creative tools landscape. Open source tools have evolved a lot in the past few years, so let's take a tour of 2016 landscape. read more

Yes, my fellow penguins, it is time for the annual ritual of having fun with silly Linux holiday commands! The fun of being a grownup is you get to make your own observances, and Linux silliness is one of mine. Without further ado let us plunge into our maelstrom of Linux holiday delights.

Because they spend most of their days looking at them, most sysadmins and developers are pretty choosy when it comes to picking a monospaced font for use in terminal emulators or text editors. Here are six great monospace fonts that... Continue Reading →

This article explains how to configure and set up Clair vulnerability scanner for Docker images on OpenPOWER servers.

DigitalOcean launched Hacktoberfest in 2014 to encourage contribution to open source projects. The event was a clear success, and in terms of attendance and participation goals reached, it's also clear that Hacktoberfest has become a powerful force in driving contributions to open source. The lure of a t-shirt and specific, time-limited goals help new contributors get started and encourage existing contributors to rededicate themselves and their efforts.

Is virtualization still as strategically important as it was now that we are in the age of containers? According to a Red Hat survey of 900 enterprise IT administrators, systems architects, and IT managers across geographic regions and industries, the answer is a resounding yes. Virtualization adoption remains on the rise, and is integrated with many cloud deployments and platforms.

The tiny, open-spec, Kodi-oriented “Khadas Vim” SBC has a quad-core, Cortex-A53 Amlogic S905X, plus WiFi, BT, 2GB RAM, and 8GB ($50) or 16GB ($65) eMMC. A Chinese startup called Khadas has launched an open source Khadas Vim single board computer that runs on the Amlogic S905X, a lower-cost upgrade to the quad-core, Cortex-A53 Amlogic S905 found on Hardkernel’s Odroid-C2 hacker SBC.
