Go has popularized the mantra don't communicate by sharing memory; share memory by communicating. The language does have the traditional mutex (mutual exclusion construct) to coordinate access to shared memory, but it favors the use of channels to share information among goroutines. read more

This article is the second in my series "Road to RHCA", where I'm charting my journey to the Red Hat Certified Architect designation—a designation that's difficult to come by.

The first time I used DevPI, I was getting ready for a camping trip with my wife and kids. By "getting ready" I do not mean practicing my s'mores-making skills. I mean that I knew my kids would be entertained by camp staff some of the time, and I planned to fix a few bugs in the Twisted package. I also knew I would not have internet on the campgrounds, so I needed to be able to develop without connecting to the internet. read more

As open source has become more pervasive, it has also profoundly impacted the job market. Across industries the skills gap is widening, making it ever more difficult to hire people with much needed job skills. In response, the demand for training and certification is growing.

Nvidia unveiled a Jetson Xavier Developer Kit for its octa-core, AI/robotics focused Xavier module. The carrier includes eSATA, PCIe x16, GbE, 2x USB 3.1 Type-C with DP support, and 2x M.2 slots with NVMe support.

Guido van Rossum, the "Benevolent Dictator For Life" of Python, has had enough and is walking away from leading the popular open-source language.

Cluster computer projects are increasingly looking beyond the Raspberry Pi to build devices with faster cluster-friendly SBCs. Here’s a 96-core monster that taps the octa-core NanoPi Fire3. Cluster computers constructed of Raspberry Pi SBCs have been around for years, ranging from supercomputer-like behemoths to simple hobbyist rigs.

Python's Benevolent Dictator For Life (BDFL) Guido van Rossum today announced he's stepping down from the role. On the Python mailing list today, van Rossum said, "I would like to remove myself entirely from the decision process. I'll still be there for a while as an ordinary core dev, and I'll still be available to mentor people—possibly more available. But I'm basically giving myself a permanent vacation from being BDFL, and you all will be on your own."

Love it or hate it, for most of us, email is indispensable. And despite years of being told about the next big thing that's here to replace it, email doesn't appear to be going away any time soon. read more

Docker Swarm is a tool that allows you to deploy a cluster of Docker Hosts. It's a native clustering tool provided by Docker which provides high-availability and high-performance for your application by distributing it to all nodes inside the swarm cluster. In this tutorial, we will show you step-by-step how to create a Swarm Cluster using Ubuntu 16.04 LTS.

Axiomtek’s “MANO311” industrial thin Mini-ITX board runs Fedora, Ubuntu, or Win 10 on a dual-core Celeron N3350, and offers triple display and 4K support plus 6x serial, 6x USB, and SATA, mSATA, PCIe, and mini-PCIe. Axiomtek has released a thin-profile Mini-ITX board with wide-range power and a moderately extended 0 to 60?C range. The MANO311 […]

VIDEO: There's a new release of the Xen hypervisor, but it's far more than just a minor update.

Cluster computers constructed of Raspberry Pi SBCs have been around for years, ranging from supercomputer-like behemoths to simple hobbyist rigs. More recently, we’ve seen cluster designs that use other open-spec hacker boards, many of which offer higher computer power and faster networking at the same or lower price. Farther below, we’ll examine one recent open source design from Paul Smith at Climbers.net that combines 12 octa-core NanoPi-Fire3 SBCs for a 96-core cluster.

In Linux, if you ever need help regarding a command, all you need to do is to open its man page. But what if a situation arises wherein the requirement is to quickly search the names and descriptions of all available man pages? Well, Linux has got your covered, as there exists a command dubbed apropos that does exactly this for you.
