Plain text is the most resilient format for documents. Plain text documents are small, transfer quickly between machines, and can be read on any device. Therefore, it makes a lot of sense to take notes in a plain text document.

When you learn a new programming language, it's good to focus on the things most programming languages have in common:

• Variables – places where information is stored
• Expressions – ways to calculate things
• Statements – the means by which state changes are expressed in a program

These concepts are the basis of most programming languages.

This is an edited excerpt from my forthcoming book on Trust in Computing and the Cloud for Wiley and leads on from a previous article I wrote called Trust & choosing open source.

This year, we are looking at all-in-one solutions in addition to strategies to help in 2021. Welcome to day 4 of 21 Days of Productivity in 2021. In this article, I'll examine a strategy for prioritizing tasks on a to-do list. To find the open source tool that suits your routine, check out this list. 

I work with multiple servers with various architectures (e.g., Intel, AMD, Arm, etc.) when I'm testing software on Linux. Once I've provisioned a Linux box and the server meets my testing needs, I still have a number of steps to do:

In 2020, Java marked its 25th anniversary and, despite its age, remains strong and active. Its seven to 10 million developers make it one of the top three languages in use today, according to the TIOBE Index.

For the past 10 years, I've worked remotely most of the time, but when I go into the office, I sit in a room full of fellow introverts who are easily disturbed by ambient noise and talking. We discovered that listening to music can suppress office noise, make voices less distracting, and provide a pleasant working environment with enjoyable music.

KubeLinter is an open source project released by Stackrox to analyze Kubernetes YAML files for security issues and errant code. The tool covers Helm charts and Kubernetes configuration files, including Knative files. Using it can improve cloud-native development, reduce development time, and encourage DevOps best practices.

Like many of us, I have a love/hate relationship with email. Email was one of the earliest means of communication on the proto-internet, corporate LANs, and the dial-up BBS ecosystem. Email was, and still is, one of the primary means of electronic correspondence. It is used for business communications, commerce, notifications, collaboration, and a pile of useful things.

The Linux command line provides a great deal of flexibility. Whether you are managing a server or launching a terminal window on a desktop system, the command line brings with it an extensive toolkit to update files, tweak system performance, and manage processes. The command line is where it's at.

Testifying to the command line's popularity, Opensource.com publishes many excellent articles about how to get the most out of your system. The following were some of Opensource.com's most-read articles about Linux commands in 2020:

Happy new year! 2020 was one heck of an unusual year with the COVID-19 pandemic pushing us to stay at home and dramatically transforming our lifestyles. However, a time like this is also the best time to start picking up a new programming language or to level up your existing programming skillset. We begin with some light reading: What is your first programming language? and Why developers like to code at night. Next, we have articles about some specific programming languages like C, D, and Awk.

Bash is the default command line shell on most Linux systems. So why not learn how to get the most out of it? This year, Opensource.com featured many great articles to help you leverage the power of the Bash shell. These are some of the most-read articles about Bash:

Ceph is an open source software storage platform that provides object, block, and filesystem storage in a unified storage cluster. I first used Ceph when I integrated it with OpenStack. At first, I was confused about why I should use Ceph since storage devices are widely available.

Like nearly everyone, 2020 was a bit rough on me, with many unexpected changes. That meant I missed every single event this year, even though all of them were virtual. As things settled down a bit over the holidays, I started looking around to find out what I missed.

In case you're in the same position, I'll walk you through the virtual events that you should have seen in 2020. The good news is, since they were all virtual, you can still watch them.

Opensource.com publishes a wealth of information on a wide range of technical topics. Everyone has their favorite subjects to learn about, yet stories about the various programming languages seem to be of special interest to our readers.

When I’m not at work on my Linux desktop, you can usually find me writing code for a legacy 16-bit system. FreeDOS is an open source DOS-compatible operating system that you can use to play classic DOS games, run legacy business software, or develop embedded systems. Any program that works on MS-DOS should also run on FreeDOS.
