Drive space isn't quite as precious as it was in the early days of computing, but no matter how much space you have, there's always the potential to run out. Computers need a little space just to operate, so it's important to check occasionally to ensure you haven't inadvertently used up literally all the space available on your drive. In the Linux terminal, you can do that with the df command.

Will 2021 prove to be the year privacy went mainstream? Our guest author discusses events pointing to a turning point in favor of consumer privacy. The post 2021: The year privacy went mainstream appeared first on The Mozilla Blog.

Axiomtek’s Linux-ready, Apollo Lake based “ICO300-83M” DIN-rail PC offers ATEX/C1D2 certification for safe operation in highly explosive environments. Isolated I/O includes 3x GbE, 6x COM, and DIO, and you also get SATA, M.2, and 2x mini-PCIe. Axiomtek announced a rugged, fanless DIN-rail system billed as being “explosion proof.” The ICO300-83M may be tough, but it’s not likely to withstand a nearby explosion.

WildFly, formerly known as JBoss Application Server, is an open source Java EE application server. Its primary goal is to provide a set of vital tools for enterprise Java applications. According to the Jakarta EE 2020/2021 survey, WildFly is head and shoulders above in the recent application servers and in the rating categories. Here are some of the reasons why:..

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.
