As we ring in a new year that many hope will look a lot different than 2020, I propose we try to keep a few things that difficult year gave us: read more

There are a lot of text editors available. There are those that run in the terminal, in a GUI, in a browser, and in a browser engine. Many are very good, and some are great. But sometimes, the most satisfying answer to any question is the one you build yourself.

Fedora Project Leader recaps the year in Fedora and the success we've had as a community in a difficult year.

The advantage of plain text is that there’s no extra computer-specific information cluttering up your otherwise human-readable writing. The good thing about computers is that they’re programmable, and so as long as we humans agree to follow very specific conventions when writing, we can program computers to interpret human-readable text as secret instructions. For instance, by surrounding a word with two asterisks, we not only give a visual cue to humans that a word is significant, but we can also program computers to display the word in bold.

If you're a fan of scripting languages like Bash, Python, or Ruby, you might find Lua interesting. Lua is a dynamically typed, lightweight, efficient, and embeddable scripting language with an API to interface with C. It runs by interpreting bytecode with a register-based virtual machine, and it can be used for everything from procedural programming to functional programming to data-driven programming. It can even be used for object-oriented programming through the clever use of arrays, or tables, used to mimic classes.

As in recent years, Python proved a popular programming language in 2020. Each year, Opensource.com publishes various articles about Python to pique new users' interest and help long-time Pythonistas expand their skills. The following are Opensource.com's top 10 articles about Python in 2020.

The Semitic root q-d-m in Aramaic, Hebrew, and Arabic is usually associated with moving forward or making progress. The Arabic word taqaddum (?????) means "progress." Progress is important. As every feel-good movie will tell you, the journey is as important as the destination.

Elastic Container Service is a fully managed container orchestration service provided by AWS. In this article, we will create an ECS cluster and deploy a sample Nginx application onto it. We will create a test cluster to understand the cluster setup. You are advised to set up a production cluster with a customized configuration as per the requirement.

The Haiku operating system is a bold but successful attempt at reviving an old OS called BeOS. In the 1990s, BeOS was positioned to become the foundation for the next evolution of the Apple Mac line of computers. Back in the 1990s, Apple Inc. was poised to acquire BeOS as its next generation operating system. At the last minute, however, Apple decided the price was too steep and acquired the UNIX-based NeXT operating system instead (and so Mac OS X was born). read more

Recently, I stumbled on an old MacBook Pro 13" from late 2011, with a 125GB SSD and 8GB RAM. I've taken this machine on trips around the world, and back in the day, I ran many a session, workshop, or demo to share all the AppDev goodness from JBoss technologies. After verifying that its battery works, charging it up, and reinstalling a new OS X, it turns out that the Safari browser version is limited to an old security specification, which means it can't connect to a lot of HTTPS sites now. This renders this solution defunct. What to do with this old thing? read more

KeeWeb is an open-source password manager used to store passwords both online and offline. It is compatible with KeePass and also available as a web version and desktop apps. In this tutorial, we will show you how to install the KeeWeb password manager on Ubuntu 20.04.

There are a couple of ways to learn a programming language. If you're new to coding, you usually learn some basic computer coding concepts and try to apply them. If you already know how to code in another language, you relearn how coding concepts are expressed in the new language.

I’m a fan of text editors that make it easy for you to learn how to use them. GNU nano is my favorite example of this: you launch nano, and you see a list of the most common commands along the bottom of the window throughout your entire session. Joe’s Own Editor (that’s joe for short) is another great example.

If you want to contribute to the Fedora project and community, participating in a test day is an excellent way to start. This test week will focus on the linux kernel 5.10 for Fedora.

2020 was the year remote work became the norm. Due to the COVID-19 pandemic, people and companies shifted to "temporary" remote work, though many have now extended it indefinitely. As remote work will be the norm for the foreseeable future, here’s a review of some of the many articles published on Opensource.com regarding remote work practices, tools, and activities to manage this new normal. read more

There’s a somewhat obscure feature in Linux and Unix shells that allows you to open a sort of do-while loop for the cat command. It’s called the heredoc, and it enables you to have, more or less, a text editor no matter what shell you’re using.

Looking back through Opensource.com's articles about DevOps in 2020, there was a bit of something for everyone—from people starting the DevOps journey to seasoned DevOps veterans. The articles focused on testing, software methodologies, and DevOps' most important part: the people. Here are the top 10 DevOps articles of 2020.

In this article, we will create an inventory configuration to store object metadata in CSV format. We can store reports in the same bucket as the source bucket, but we will use a different bucket to store this than the bucket for which we will be creating this inventory configuration.
