Writing can be hard. One of the main obstacles that people encounter when sitting down to write something is all the distractions that a modern desktop throws at you such as cats on the internet, cats on twitter, and cats... Continue Reading →

I have always interested in historical dates and determining what actual day of the week an event occurred on. What day of the week was the Declaration of Independence signed? What day of the week was I born on? What day of the week did the 4th of July in 1876 occur on? I know that you can use search engines to answer many of these questions. But, did you know that the Linux command line can supply those answers too? read more

"Organizational culture" is something plenty of people are puzzling over today, and with good reason. More and more leaders are realizing that the culture permeating and guiding their organizations will determine whether they succeed or fail. The term “organizational culture” refers to an alignment between two forces inside an organization: values and behaviors. Aligning those forces productively is one of the most difficult and important tasks facing leaders today. read more

Arduino LLC’s $22 “MKRZero” shrinks the guts of the Arduino Zero board to the 65 x 25mm size of a MKR1000, but without the MKR1000’s WiFi. Earlier this year when Arduino LLC debuted its $35, IoT focused MKR1000 board, we suggested it was like combining an Arduino Zero with its WiFi Shield. With its new […]

The task of securing Linux systems is so mind-bogglingly complex and involves so many layers of technology that it can easily overwhelm developers. However, there are some fairly straightforward protections you can use at the very core: the kernel.

I've been doing open source documentation for a long time. Over the past decade, there have been a lot of attitude shifts regarding authoring and publishing. Some of these trends seem to go in cycles, such as the popularity of semantic markup. The latest trends move documentation closer to code, what many have called docs as code. Let's look at a few of the larger themes in documentation trends.........

For today, in this final part of this series, we'll go into detail on how to set up virtual users and mailboxes in Dovecot and Postfix. It's a bit weird to wrap your mind around, so the following examples are as simple as I can make them.

As 2016 draws to a close, we looked back at some of the highlights from ApacheCon and Apache Big Data and collected the 7 videos from our most-read articles about the events in 2016. These videos help highlight the good work the open source community accomplished for and with Apache projects this year.

This article is the fourth in my series about the Qubes operating system, a security-focused Linux distribution that compartmentalizes your common desktop tasks into individual VMs.

Let's take a trip back in time to the early, simpler days of the web. A time when most of us used low-powered PCs or dumb terminals, often over slow dial-up connections. We generally visited web pages using command-line, text-only browsers like the venerable Lynx. read more

During OSCON a few years ago, Nicole Engard stopped to chat with a few representatives of women-in-tech nonprofit ChickTech. Today, she's the founder and coordinator of the organization's chapter in Austin, Texas. In her lightning talk at All Things Open, Engard shared a bit about her personal journey to ChickTech as well as some of the organization's goals for the future. read more

The performance of Linux-based network solutions was one of the biggest issues in the past and that's why Intel started the Data Plane Development Kit (DPDK) project. The goal of the ODP environment is to provide a cross­platform framework for data plane applications. OpenFastPath (OFP) is another open source implementation of a high-performance TCP/IP stack which is helpful for network applications with a traditional Linux stack. In this tutorial, OFP will be installed on an Ubuntu 16.04 VM.

Grasping the nuances of hardware supply chains and their management is straightforward—you essentially are tracking moving boxes. Managing something as esoteric as resources for building software with a variety of contributions made by the open source community is more amorphic. read more

Eurotech’s “CPU-161-18” is a headless COM Express Type 6 Compact module with a 12-core Xeon-D, up to 24GB DDR4, PCIe x16, and wide temperature operation. Like Advantech’s SOM-5991, Eurotech’s CPU-161-18 is “server-class” COM Express Type 6 Compact module aimed at high-end embedded applications, and equipped with Intel’s 14nm “Broadwell” based Xeon D-1500 SoCs. The module […]

Pure Engineering’s Arduino IDE compatible “PUREmodules” kit offers solderless IoT prototyping, and features a Nordic NRF52 Bluetooth SoC and sensors.

Ceph is a widely used open source storage platform. It provides high performance, reliability, and scalability. The Ceph free distributed storage system provides an interface for object, block, and file-level storage. Ceph is build to provide a distributed storage system without a single point of failure. In this tutorial, I will guide you to install and build a Ceph cluster on CentOS 7.

Documentation is one of those areas that never feels quite finished. There are almost always areas that could be updated or improved in some way. In his talk at LinuxCon Europe, Chris Ward provided a crash course on ways to make documentation for your projects better, starting with thinking about how to answer the three W’s:

Election night for the US presidential election as come and gone, but the memory of our hackathon lives on. read more

In the first article in this series, I introduced the rsyslog tool for logging, and in the second article I provided a detailed look at the main config file. Here, I’ll cover some logfile rules and sample configurations.

Because the Linux kernel community celebrated a quarter-century of development in 2016, many people have asked us the secret to the project's longevity and success. I usually laugh and joke that we really have no idea how we got here. The project has faced many disagreements and challenges along the way. But seriously, the reason we've made it this far has a lot to do with the community's capacity for introspection and change. read more
