Securing your Docker containers and the hosts upon which they run is key to sustaining reliable and available services. From my professional DevSecOps perspective, securing the containers and the orchestrators (e.g., OpenShift, Docker Swarm, and Kubernetes) is usually far from easy. This is primarily because the goal posts change frequently thanks to the technology evolving at such a rapid pace.

I have no idea what you did at your job last week. I couldn't find out if I wanted to. But if you were curious enough about it, you could find out exactly what I did, Monday through Friday. read more

I recently installed the latest release of Fedora 26 from scratch on a brand new laptop. If you've been using Linux for a while, you may opt to do upgrades instead of fresh installs to keep your preferences and configurations intact. After all, who wants to go searching for customizations every time a new version of your favorite distribution (in my case, Fedora) comes out? read more

Having open-source programming chops or Linux sysadmin skills is only the start.

Instead of relying on servers concentrated in one large data center, the new Kubermesh is designed to simplify data-center architectures for smart factories by elegantly and cost effectively leveraging a distributed network of computing nodes spread across the enterprise.

Distributed denial-of-service (DDoS) attacks continue to be a weapon of choice among threat actors seeking to extort money from victims, disrupt operations, conceal data-exfiltration activities, further hacktivist causes, or even to carry out cyberwar.

Eurotech’s rugged, Linux-driven “BoltMAR 20-11” mobile access router offers Cisco 5921 ESR software, dual Ethernet ports, and WiFi, GPS, and cellular links.

Like other blog software, you can make both timed posts and static pages. Pelican supports feeds, external analytics tools, and can import from WordPress or other feeds.

While grep is a well-known Linux command (we've already covered it in detail), do you know that there exist two different variants of this tool? Yes, these are egrep and fgrep. In this tutorial, we will discuss the latter (fgrep) using easy to understand examples.

There comes a time in the journey of most any programmer when they are ready to branch out past the basic examples and start to build a graphical interface to their program. In Python, the steps to get started with GUI programming are not terribly complex, but they do require the user to begin making some choices. By its nature as a general purpose programming language with interpreters available across every common operating system, Python has to be fairly agnostic as to the choices it presents for creating graphical user interfaces. read more

Building modern software in a predictable and repeatable way isn't easy. The overwhelming number of software dependencies and the need to isolate conflicting components presents numerous challenges in managing build environments. Although there are many tools aimed at mitigating this challenge, there are two approaches most of them take: either they rely on package managers to preserve and replicate package sets, or they use virtual or physical machines with preconfigured environments. read more

Have you ever wondered why some open source projects have better luck than others when it comes to attracting and retaining enthusiastic contributors? Here are a few ways open source projects can improve their chances of getting—and keeping—the kinds of contributors who help make projects succeed. read more

The cool thing about Linux and FOSS is also an aggravating thing, which is that sometimes there's too much of a good thing. There is such an abundance of goodies that it can be overwhelming. So I am here to help you decide which programming language you should learn next, and that is Python. Oh, yes, it is.

With a new school year beginning in many areas, now is a great time for parents, students, and educators to try out apps that can help with the learning experience. The following eight apps can turn an Android phone or tablet into a tool to help a student learn and study. They are all open source and all of them are available from the F-Droid repository, so you easily add these apps to any phone that is configured to allow apps from external repositories. read more

This is the third in a series of articles on system administrator fundamentals where I focus on some lessons I've learned through the years that might be obvious to longtime sysadmins, but news to someone just coming into this position.

AspenCore has released the results of an embedded technology survey of its EETimes and Embedded readers. The survey indicates that open source operating systems like Linux and FreeRTOS continue to dominate, while Microsoft Embedded and other proprietary platforms are declining.
