Git is an indispensable part of the code-sharing development workflow. Be you a beginner or an expert, this powerful version control system is the first thing you are expected to learn when working with open source code. You don't need to know everything under the sun when it comes to Git, but knowing specific hacks makes sharing your code a lot easier on platforms like GitLab, so you can collaborate with developers far and near. If there's something you're not sure about, git --help can come to your rescue.

Anyone can get started in programming. We all started somewhere, and you don't need to have a computer science background to learn to code. That's the power of Linux and open source—anyone can learn a bit of coding.

If you want to learn a new programming language, we have several great articles to get you started. Below are a few of our most popular articles to help you.

2021 has been an exciting year for DevOps as teams continue to adjust to remote and hybrid working models. The DevOps articles that made our most-read list this year show how our community focuses on tools, innovation, best practices, and transformation.

The Internet of Things (IoT) is a fascinating development in the realm of computing. Connected smart devices, home automation, and related areas of development are producing many interesting projects. Opensource.com's writers shared their expertise about a variety of Internet of Things projects many times during 2021. Here are Opensource.com's ten best Internet of Things articles from the year.

I am privileged to be here at Opensource.com as the new community manager. I'm looking forward to working with existing correspondents and contributors, and also bringing in new contributors and increasing the diversity of thoughts and ideas shared here on Opensource.com.

I moved through several lifetimes before coming into tech and all have shaped me into who I am as a contributor to open source. Here are some of the most impactful experiences of my life so far:

2021 has been an exciting year for Kubernetes, and these articles prove it. From fun interfaces to homelabs to development environments, check out my favorite articles from 2021, K8s style.

Open source has a learning solution for you no matter where you are on the education continuum. This year our writers provided readers with a wide variety of articles that spanned that spectrum from PreK-12 to higher education. Here are 12 you won't want to miss:

This year, Opensource.com ran several great articles focusing on open source in business. These articles show the power of open source in business as tools, platforms, or integration points. Let's review some of the top open source business stories from 2021:

This year we learned a lot about our community as we embraced our new work-from-home lives. We also met some amazing folks who are leveraging Linux and open source software in their organizations. 

Open source software isn't just about creating alternatives to proprietary software. On the business side, open source has become a "force multiplier" to transform how organizations do business. At the same time, more companies have started to adopt more open source methodologies, even in managing teams and processes.

In the last year, we ran many great articles that show how businesses connect with open source software. Here are some of the most-read articles:

2021 was another year spent largely online, but that's nothing new for the open source world. The ability to work from anywhere is in our DNA, preceding the pandemic that ushered remote work into the mainstream.

Still, all that time in front of screens this year made our community consider open source alternatives. Regardless of the tool type you need, many of the most popular vendors are not your only option.

The Raspberry Pi is one of the most popular brands of single-board computers. Part of the reason for this popularity is the massive number of unique and interesting projects that people have built using Raspberry Pi. Several Opensource.com authors have used Raspberry Pi in various projects and provided instructions so others can recreate their projects. Here are the ten most popular Raspberry Pi articles published by Opensource.com in 2021. I hope they inspire you as you tinker with your own Raspberry Pi.

Whether you celebrate Christmas or not (our family does, as it happens), this time of year is one where presents are often given and received. I thought it might be nice to think about what presents we could give in the spirit of open source.

There are many great synthesizers for Linux, and like synthesizers in real life, most of them can be controlled using the MIDI protocol.

Opensource.com published well over 150 articles about Linux in 2021. From articles about small utilities for desktop Linux users to tutorials about working with Linux as a server operating system and everything in between, these articles have covered many facets of the Linux ecosystem. It is well worth your time to check out all of them, but here are ten great articles published this year to get you started.

A wall of synth. That's what I dream of. Given the chance, on one wall of my office, I'd have a modular synthesizer that only Bob Moog himself could truly ever understand. Until I realize this dream, I make do with a very good approximation: Zyn-Fusion.

The ongoing pandemic kept 2021 far from normal, yet there were glimmers of hope through the uncertainty. In-person conferences slowly resumed, if smaller and with more masks than in years past. And the asynchronous essence of open source allowed many people to keep working on passion projects while growing their careers.

As a full-stack developer, especially a front-end developer, DevOps technologies and the way DevOps developers think were always a mystery to me. When the company I work for launched a new command-line interface (CLI) application called Gatekeeper, I jumped into the world of DevOps and Kubernetes, and what I learned turned out to be very valuable. I now have a much better understanding of Kubernetes and the DevOps pipeline, and I can better explain how our CLI application supports them both.

Simplicity is sometimes undervalued. Something that's simple is often seen as the result of laziness or as something trivial. But there are many instances when simplicity is very useful. Consider logo design, for example. Many of the most famous logos are the ones designed to be simple and easily reproducible. Think about the Signal logo, the LibreOffice logo, or the KDE logo. They use basic shapes, are not cluttered, and are recognizable.

One of the most prevalent discussions on Opensource.com in 2021 was about the security and privacy of your own data. A noticeable theme was that your data is yours and that passwords were key to security. This year's security authors provided helpful tips and open source tools for keeping your data and hardware secure.

Here is my top-five countdown of this year's security journey.
