Ladies and gentlemen, we've left Mars. Well, at least I'm done with the Martian lander from my past few articles. I hope you had chance to experiment with it and find out that it's not too easy to land a craft on any planet!

"A good engineer is a lazy engineer," some will say. And to a certain extent, it's true: Laziness is a great quality if you're automating repetitive tasks. But laziness flies in the face of learning new technologies and getting new work done. Somewhere between Junior Systems Administrator and Senior DevOps Engineer, laziness no longer becomes an advantage. Let's discuss the five laws aspiring DevOps engineers should follow if they want to become great DevOps engineers. read more

Adlink launched a rugged, Linux-ready “MVP-5000” industrial PV with 6th Gen Core processors, up to 32GB DDR4 RAM, and mini-PCIe based wireless options. The MVP-5000 is a close cousin to last year’s MVP-6000, the first in Adlink’s “value line” series of rugged, fanless MVP computers, which offer much of the functionality of its MXE line […]

DevOps is mostly about culture change. Being successful is all about finding ways to bridge the gap between the builders and the maintainers, bringing projects to fruition and updating them in shorter cycles to maintain a competitive advantage. But at the end of the day, you need the right tooling to make it all work. read more

Elementary OS, my dear penguin? With the death of Unity, Canonical will focus more attention on Ubuntu servers, Ubuntu in the cloud and Ubuntu in the so-called Internet of Things.…

Windows will almost certainly never be open source, but virtually all Microsoft Windows engineers are now using the open-source program Git to build Windows on.

MinnowBoard.org’s “MinnowBoard Turbot Quad” and Aaeon’s UP Squared SBCs began shipping, featuring community sites and Intel SoCs running Linux and Android. On May 23, Intel-backed MinnowBoard.org and ADI Engineering began shipping the first quad-core MinnowBoard, selling for $190.

Joining any new company—with an established culture and programming practices—can be a daunting experience. When I joined the Ansible team, I decided to write up the software engineering practices and principles I’ve learned over the years and to which I strive to work. This is a non-definitive, non-exhaustive list of principles that should be applied with wisdom and flexibility. read more

At one point in time, when you wanted to attach an external block storage device to a server, you mapped it as a Logical Unit (LU) across a Storage Area Network (SAN). In the early days, you would do this over the Fibre Channel (FC) protocol. More recently, iSCSI (SCSI over IP) has usurped FC in most data centers.

As we mentioned in the previous article, web browsers present the largest and the most exposed attack surface on your Linux workstation. We’ve already discussed some best practices that Linux sysadmins can follow to reduce the impact of a compromised browser, such as upgrading to Wayland, using a different browser for work/high-security sites, and using Firejail to create a sandbox around Linux applications.

The things we do for family, eh? Sometimes I wonder why I do it to myself, this not being the first time my perfectionism has led me to do far more work than a task originally required. read more

In this tutorial, I will show you step-by-step how to install Oracle 12c on a CentOS 7 x86-64 machine. This includes the preparation and configuration of the CentOS 7 machine for the Oracle 12c installation, the Oracle 12c installation and testing the database with the Oracle Database command line utility sqlplus and the web-based Oracle Enterprise Manager.

When you think of open source technologies, you probably think of the stalwarts, the technologies that have been around for years and years. It makes sense: According to a survey conducted in Q4 of 2016 by my company, Greythorn, 30%+ of participants said established technologies are among the top ten they primarily use. read more

The next major Red Hat Enterprise Linux update is on its way.

We’re introducing major upgrades for our educational, browser-based code editor. Learning to code—from getting the hang of HTML tags to mastering the nuances of JavaScript—shouldn’t be a challenge.

As a principal agile coach, my focus is to energize and inspire developers to adopt and follow through on the agile frameworks across our teams. Initially, I failed, as I didn't really understand the mindset of teams that have been working in an open source ecosystem. My assumption was that since agile and open source values align so closely, the barrier for adopting agile frameworks would be low and our people would take to it like fish to water. read more

Chef, the popular DevOps company, has expanded its Chef Automate program to handle cloud-native and container-first server environments.

Lime Micro has launched three open source “LimeNET” SDR systems that run Ubuntu Core on Intel Core CPUs, including one with a new LimeSDR QPCIe board. Lime Microsystems has gone to Crowd Supply to launch three fully open source LimeNET computers for software defined radio (SDR) applications. The systems run Ubuntu “Snappy” Core Linux on […]

I've written a little about PHP before, because I think it's a great utility language for writing quick things you need to do. Plus, it allows you to use a web browser as your interface, and everyone has a web browser. That makes it very convenient for my family, because I can make simple web interfaces for the various things I normally have to do from the command line.

When you're working in an organization where statements like "Good ideas can come from anyone" and "Experiment! We learn more from our mistakes than our successes!" are commonplace, does saying "no" create a contradiction that impedes adaptability and inclusivity? The answer depends on how you say "no" and the things you say "no" to. read more
