Red Hat is collaborating with Nutanix to make OpenShift and Red Hat Enterprise Linux a fully supported solution on the Nutanix native virtualization platform, AHV. The new agreement provides for Red Hat OpenShift, its Kubernetes distribution, to be the Nutanix "preferred choice" for Kubernetes on Nutanix, and for Nutanix HCI to be fully supported by Red Hat for deploying Enterprise Linux (RHEL) and OpenShift. The Nutanix Acropolis Hypervisor (AHV) will now be certified by Red Hat for RHEL and OpenShift.

Let me start with a brief background to give my stories some context. I worked in desktop support for a couple of years before becoming a technical trainer on various platforms (Windows Server, different Linux distributions, Cisco, etc.). Eventually, some former students approached me to work as the network/systems administrator for their small organization (about 65 users). I worked there for a couple of years—an experience that inflated my already robust sense of cynicism. I freely admit that many of my observations are based on very small organizations (fewer than 100 users) and companies whose cultures did not easily embrace technology. I later returned to the training industry, though I did various consulting projects on the side. From those years come these anecdotes.

EteSync is an open-source solution to sync your contacts, calendars, and tasks. In this tutorial, I will show you how to install EteSync with Apache on Ubuntu 20.04.

The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced it will host Pyrrha, created and contributed by Prometeo Platform S.L., in collaboration with IBM to help accelerate the development and deployment of firefighter safety technology around the world. In 2019, Prometeo was named the winner of the Call for Code Global Challenge and since then their technology has been further developed with updated hardware and enhanced software through work with the IBM volunteer Service Corps and leading ecosystem partners.

Sysdig is an open-source and comprehensive activity monitoring tool for Linux. It is used to capture and analyze application logs and helps you to troubleshoot system-related issues. In this post, we will show you how to install and use the Sysdig monitoring tool on Linux.

MYIR’s tiny “MYC-YA15XC-T” module runs Linux on ST’s STM32MP1 with up to 512MB DDR3L and 4GB eMMC and optional -45 to -85°C support. The module is supported with a “MYD-YA15XC-T” dev kit. MYIR announced a 39 x 37mm MYC-YA15XC-T module as a more compact alternative to its 45 x 43mm MYC-YA157C module, which similarly runs Linux on STMicroelectronics’ 650MHz to 800MHz, single- or dual-core, Cortex-A7 STM32MP1. The SoC also integrates a 209MHz Cortex-M4 MCU, cryptography, and secure boot.

UBports, which took on the task of maintaining the Ubuntu Touch mobile OS after Canonical abandoned it, has released OTA-18 with lots of improvements, but still based on the ancient Ubuntu 16.04. According to the team, one of the big changes in this release is a rewritten Media-hub service, responsible for media playback and control. "20,526 lines of code later, the new media-hub emerged – with better tests, a more contributor-friendly structure, and a few fixed bugs to boot," said the post introducing the release.

RTFM: Read the [fine] manual. Traditionally the Darktable project only releases one update a year, with a new version arriving on Christmas day. But the developers behind Darktable have been adding new features and improving existing ones so quickly that one a year is no longer enough.

It is no secret that email is the preferred method of communication for businesses - a trend that has only been magnified with the increase in remote workers brought on by the pandemic. That being said, email is effectively a plaintext communication sent from email clients to receiving email servers or from one server to another, leaving the content of messages in transit vulnerable to compromise without additional protection via encryption technology such as the Transport Layer Security (TLS) standard.

The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced the keynote speakers for Open Source Summit + Embedded Linux Conference 2021, taking place September 27-30 in Seattle, Washington. The events are being produced in a hybrid format, with both in-person and virtual participation available, and are co-located with OSPOCon and Linux Security Summit, among others.

Minikube is an open-source tool that helps you to set up a single-node Kubernetes cluster on your local machine. In this tutorial, we will show you how to install Minikube on Ubuntu 20.04 server.

Communities and the value they inherently have in our lives has never been more highlighted than over the past year as we deal with a global pandemic keeping us home, away from conferences and events, and busy with the complexities of childcare, elderly care, working remote, and more. 

Recent years have demonstrated that Windows users are not the only ones who should be concerned about malware. Linux is becoming an increasingly popular target among malware operators due to the growing popularity of the open-source OS and the high-value devices it powers worldwide. Security researchers from AT&T Alien Labs are now warning that ''cyber gangs have started infecting Linux machines via a fileless malware installation technique that until recently was more commonly used against Windows-based systems''.

If you happened to have a time machine and chose to shoot yourself back a year to ask me what I thought about making open source contributions (of all the things you could've done), you may have guessed that I would just shrug and say something along the lines of, "I don't know, isn't that reserved for all the hard-core devs with the insane GitHub stats and decked-out macros and stuff? I'd have no idea what I was doing, and who would even care what some random college student had to say about their code?" And you'd probably be correct.

Virtualization is one of the most used technologies. Fedora Linux uses Cloud Base images to create general-purpose virtual machines (VM), but there are many ways to set up Cloud Base images. Recently, the virt-install command-line tool for provisioning VMs added support for cloud-init, so it can now be used to configure and run a cloud image locally.

In prior years, this annual series covered individual apps. This year, we are looking at all-in-one solutions in addition to strategies to help in 2021. Welcome to day 6 of 21 Days of Productivity in 2021.

When people learn that I work as an open source evangelist (focusing on syslog-ng and sudo), they often ask me what it's like to represent such well-known names in the Linux world. My short answer: It's good! I am part of research and development, so it is never boring. I feel that I make an impact when people implement what they learn from me and when the feedback I collect from users influences the development of the product.

The tKINO-UL6 is the second thin Mini-ITX board we have seen based on Intel’s 10nm fabricated 11th Gen Tiger Lake processors, following ASRock’s IMB-1224. It is also the second Tiger Lake SBC with a USB 4 port after Aaeon’s community-backed UP Xtreme i11. IEI’s more industrial focused board offers -20 to 60°C support and a 9-36V DC input.

Sometimes you need the short version. You know what you want to do and you just can't recall exactly how to do it. That's when cheat sheets come in handy. In this article, I suggest a cheat sheet to get you going with MariaDB and MySQL. This cheat sheet is great for the occasional database user. Next, I have listed two Raspberry Pi cheat sheets. The first gets you started with this single-board computer. Once you're comfortable with the basics, turn it into a home lab and begin working with Kubernetes container management.

If you're a programmer and you want to put a certain functionality in your software, you start by thinking of ways to implement it—such as writing a method, defining a class, or creating new data types. Then you write the implementation in a language that the compiler or interpreter can understand. But what if the compiler or interpreter does not understand the instructions as you had them in mind, even though you're sure you did everything right? What if the software works fine most of the time but causes bugs in certain circumstances?
