I've been on a journey from Mac to Linux since joining the staff at Opensource.com almost two years ago. In a huge step for me, I finally made the call to have my personal laptop also run Linux. Due to the coverage of System76 in our community, I thought I'd give it a shot. I'm coming from a MacBook Pro as my go-to device, so I went with a near-standard build of the Lemur Pro for a comparable system. A reasonably priced upgrade to more RAM and a speedy NVMe hard drive later, my order was on its way. read more

WordPress is best known as a website content management system, but it also a great learning management system (LMS) for delivering online courses. If that is what you are looking for out of WordPress, then H5P should be the top plugin on your list.

One way to get started with an open source community is to write about it. You can contribute to technical documentation, share how you use the software, or write an article for Opensource.com. But getting started writing is easier said than done. The two most common excuses I hear for not writing are: "I have nothing new to say" and "I'm not a good writer." I'm here to dispel both of those myths.

It's been a long time since I properly learned a new language—computer or human. Maybe 25 years. That language was Java, and although I've had to write little bits of C (very, very little) and JavaScript in the meantime, the only two languages I've written much actual code in have been Perl and Java. read more

What happened to the promise of live patching Linux kernels? This article looks at its history, its problems, and the cheapest and easiest ways to do it on Ubuntu Focal Fossa (20.04 LTS).

A few months ago, we got a requirement to provide a stable and reliable Domain Name System (DNS) server for a new project. The project dealt with auto-deployment using containers and where each new environment would generate a unique, random URL. After a lot of research on possible solutions, we decided to give PowerDNS (PDNS) a try.

Cloud-init is a standard—it would not be a stretch to say it is the standard—that cloud providers use to provide initialization and configuration data to cloud instances. It is used most often on the first boot of a new instance to automate network setup, account creation, and SSH (secure shell) key installation—anything required to bring a new system online so that it is accessible by the user.

The Free Software Foundation's (FSF) annual conference LibrePlanet went fully virtual in 2020 due to ongoing issues caused by the coronavirus pandemic. In our last week of preparations before the live event, increasingly disturbing news related to the virus made us realize we could not responsibly hold our usual conference on software freedom in person while protecting the safety of our participants and their communities.

I see this question popping up quite often in different conversations. Recently, we had a good discussion about it within my team. The main question was about how to communicate openly with the community, as well as have the space to build a team and work as a team. This can be challenging; for example, when a company or a sponsor pays a part of the contributors to work full time on a project. In this article, I will explain why agile works with the open source development model. read more
