Advent of Code, often called AoC, is a yearly coding challenge that starts on December 1st and ends on December 25th, just like an advent calendar. Each day, Participants receive a new coding puzzle to solve. The Puzzles are designed for various skill levels, making it accessible for everyone from beginners to experts.

The charm of Advent of Code is that it combines the joy of solving puzzles with the excitement of a countdown to Christmas. Participants can choose any programming language they like to solve the challenges, making it a fun way to learn and practice coding.

How It Works

Each day, participants log onto the AoC website to see a new puzzle waiting for them. These puzzles come with a story, giving a bit of context to the coding task. While the backstory is the same for everyone, the input data provided to each participant is unique.

After crafting their solutions, participants submit their results to see if they have cracked the code for that day. If they do, they can move on to the next puzzle. Each puzzle usually has two parts, and you must complete the first one to access the second. There’s also a global leaderboard that ranks participants based on how quickly they solve the puzzles.

The Community Aspect

Unlike other coding competitions that have dedicated forums for discussion, participants in AoC gather on Reddit. More specifically, they flock to the /r/adventofcode subreddit, where they discuss strategies, share their solutions, and even exchange tips. This community aspect adds a social element to the challenge, making it more engaging.

The Reddit Megathreads

For each day of AoC, moderators create "megathreads" on Reddit. These threads are like a digital campfire where participants can come together to share their solutions and thoughts on the puzzles. Participants post their answers, and other users can jump in to comment, ask questions, or offer advice.

Why is Advent of Code Popular?

Advent of Code has gained immense popularity over the years, especially during the pandemic when more people turned to online activities. In the initial year, it attracted about 52,000 participants, and by 2021, that number grew to over 180,000!

One reason for this surge in interest is the lack of time pressure. Participants can work at their own pace. If a puzzle gets too tricky, they can take a break and come back later. This flexibility allows people to learn new Programming Languages without the stress of deadlines.

Moreover, the puzzles themselves don’t always require advanced coding skills. They emphasize problem-solving, which means that even those with minimal coding experience can still participate and improve.

What We Learned from Participants

Researchers took a closer look at the discussions and interactions of AoC participants on Reddit during the 2019, 2020, and 2021 editions. They analyzed over 23,000 comments and 5,000 unique participants to better understand user behavior.

User Participation Patterns

One key finding was that the number of participants increased each year. In 2019, around 52,000 people participated. By 2021, that number had nearly quadrupled! This growth indicates that more and more people are eager to take part in AoC each year.

Interestingly, participants often stick with the same programming language throughout the challenge. However, those who join multiple years are more likely to experiment with different languages in subsequent events. This suggests that AoC encourages users to stretch their coding skills and try new tools.

Programming Language Popularity

The researchers also dug into programming language choices among participants. They found that some languages, like Python and Rust, consistently ranked at the top across the years. Participants often opt for these languages because they are well-suited for problem-solving and easy to learn.

The study revealed that the most used programming languages remained similar each year, showcasing their significance in the coding community. When it comes to switching languages, participants typically change between different editions rather than during the same event.

The Love for Languages

According to feedback gathered from Stack Overflow surveys, certain programming languages are viewed as "loved" or "popular" among the community. It turns out that participants have a tendency to stick with loved or popular languages for longer durations during AoC. This makes sense – if you enjoy using a language and it’s well-regarded by your peers, you’re more likely to use it consistently.

The Complexity of the Puzzles

As the AoC event progresses, the puzzles often get more challenging. Research found that participation tends to drop as the puzzles become tougher, with fewer users attempting to solve them towards the end. This decline is understandable; complex challenges can be intimidating and demotivating.

If you're still in it by the 25th day, you’re probably a coding warrior!

Learning and Trying New Things

One of the beautiful aspects of Advent of Code is the opportunity it provides for learning new programming languages. Many participants join in with the intention of improving their skills. The community encourages this exploration, which is a significant benefit for both new learners and seasoned developers.

While many participants start with one programming language, very few switch during the same challenge. However, when they return for another year, a notable number of users choose different languages. This indicates that AoC is a great way to encourage people to try new things and expand their coding toolbox.

The Role of Community Discussions

The discussions that take place on Reddit are equally valuable. They allow participants to share their problem-solving strategies and discuss different approaches to coding challenges. These conversations can spark inspiration and help users discover new techniques, making the whole experience richer.

Future of Advent of Code

Looking ahead, Advent of Code shows no signs of slowing down. With its fun puzzles and friendly community, it’s likely that more people will join in the coming years. The challenge not only offers a platform for honing coding skills but also fosters a sense of camaraderie among participants.

Potential Improvements

As the event evolves, there may be opportunities for further enhancements. For instance, incorporating more interactive features on the AoC website could facilitate even greater community engagement.

Imagine being able to see which solutions are popular, track progress in real time, or join live coding sessions! The possibilities are endless and could make AoC an even more immersive experience.

Conclusion

Advent of Code is not just a coding challenge; it’s a wonderful mix of competition, learning, and community spirit. Whether you're a novice coder or an experienced developer, there's something exciting about tackling daily puzzles alongside thousands of others.

So, if you’re looking to sharpen your programming skills, consider jumping into the next Advent of Code. Who knows? You might just discover a new favorite programming language or meet fellow enthusiasts who share your passion for coding. Plus, you get to enjoy a dash of holiday spirit along the way! Happy coding!

Title: Characterizing Information Shared by Participants to Coding Challenges: The Case of Advent of Code

Abstract: Advent of Code (AoC from now on) is a popular coding challenge requiring to solve programming puzzles for a variety of skill sets and levels. AoC follows the advent calendar, therefore it is an annual challenge that lasts for 25 days. AoC participants usually post their solutions on social networks and discuss them online. These challenges are interesting to study since they could highlight the adoption of new tools, the evolution of the developer community, or the technological requirements of well-known companies. For these reasons, we first create a dataset of the 2019-2021 AoC editions containing the discussion threads made on the subreddit {\tt /r/adventofcode}. Then, we propose a model based on stream graphs to best study this context, where we represent its most important actors through time: participants, comments, and programming languages. Thanks to our model, we investigate user participation, adoption of new programming languages during a challenge and between two of them, and resiliency of programming languages based on a Stack Overflow survey. We find that the top-used programming languages are almost the same in the three years, pointing out their importance. Moreover, participants tend to keep the same programming language for the whole challenge, while the ones attending two AoCs usually change it in the next one. Finally, we observe interesting results about the programming languages that are ``Popular'' or ``Loved'' according to the Stack Overflow survey. Firstly, these are the ones adopted for the longest time in an AoC edition, thanks to which users have a high chance of reaching the end of the challenge. Secondly, they are the most chosen when a participant decides to change programming language during the same challenge.
