This year saw--as it does every year--developers, maintainers, and first-time contributors working side by side, creating solutions that matter to open source. A huge thank you to everyone who participated and made this Hacktoberfest special. We saw a lot of new faces join the celebration this year, and it's exciting to see the community grow! What really stood out this year? The genuine enthusiasm. People were here to contribute, collaborate, and make a tangible impact on open source projects. That's what Hacktoberfest is all about: getting more people involved in open source and working together to improve the software that powers our world. It's fulfilling to see how Hacktoberfest continues to inspire developers and successfully achieves what we set out to do. Here's what Mike Swift, Co-founder and CEO of MLH has to say about Hacktoberfest this year: "What I enjoyed most about this year's Hacktoberfest was seeing next-gen developers step into open source with genuine curiosity and realize they could make meaningful contributions. They approached issues, learned from maintainers, and connected those experiences to the AI tools shaping their work. Being part of moments like that is incredibly rewarding and exactly why the MLH community exists." A change for Hacktoberfest This year we increased the number of PRs from 4 to 6. As the program has matured and participants have access to better onboarding resources, we increased the requirement to encourage deeper project engagement and more substantial contributions. The additional PRs allow participants to move beyond initial contributions and tackle more complex issues, leading to higher-quality work and more meaningful impact on the projects they contribute to. This change was embraced by all contribu ## The Dodo Digest: PayPal, migrations, and UPI Autopay all in motion DevFeed: [The Dodo Digest: PayPal, migrations, and UPI Autopay all in motion]() Original publisher: [Read original article]() Author: Rishabh Goel Published: 2025-11-07T00:00:00Z Content type: news Language: en Sources: [Dodo Payments Blog]() Topics: [migration](), [Open Source](), [Hacktoberfest](), [stripe]() Tags: [hacktoberfest](), [latest-release](), [migration](), [newsletter](), [open-source](), [paypal](), [product-updates]() ### AI overview Dodo Payments reports new PayPal support in EUR and GBP, expanded one-command migrations from LemonSqueezy, Stripe, Paddle, and Polar, UPI Autopay early access in India, and product improvements in release v1.56.0. ### Source excerpt PayPal support, one-command migrations, UPI Autopay early access, and v1.56.0 improvements - see what's new in this Dodo Digest. ## Hacktoberfest 2025: How to Participate DevFeed: [Hacktoberfest 2025: How to Participate]() Original publisher: [Read original article]() Author: Haimantika Mitra Published: 2025-09-29T07:06:22Z Content type: tutorial Language: en Sources: [DigitalOcean]() Topics: [Hacktoberfest](), [Open Source](), [pull-requests](), [GitHub](), [GitLab](), [Maintainers]() Tags: [also](), [community](), [contribute](), [contributions](), [github](), [gitlab](), [hacktoberfest](), [maintainers](), [open-source]() ### AI overview A guide to participating in Hacktoberfest 2025, covering registration, contribution requirements, rewards, code contributions, and ways maintainers can prepare open-source projects. ### Source excerpt Hacktoberfest 2025: How to Participate Hacktoberfest registrations are live, and we're just a few days away from kicking off the month-long celebration of open source. Every October, developers from all over the world come together to contribute their skills, big and small, to open-source projects. Code is the most common way people participate, but that's not the only way you can help. Open source thrives on more than just commits. It needs documentation, testing, design, writing, and so much more. Before we get into the how, let's cover the basics. First, the rules of Hacktoberfest: Register anytime before October 31. Contribute to projects on GitHub or GitLab that have the hacktoberfest topic. Submit at least 6 high-quality pull/merge requests between October 1 and October 31. These need to be accepted by project maintainers to count. Rewards: Everyone who signs up and gets at least one PR merged, gets a digital badge from Holopin (you can get up to 4 badges). If you're among the first 10,000 people to complete 6 merged PRs/MRs, you'll also get a limited edition Hactoberfest 2025 t-shirt. That's it! You're ready to dive in. Ways to contribute: 1. Code Contributions This is what the majority of Hacktoberfest contributions consist of. Most participants jump in by submitting code to projects they care about. Maintainers, many of whom run projects purely out of passion, appreciate thoughtful, quality code more than anything. Whether this is your 12th Hacktoberfest or your very first pull request, now's the time to fire up GitHub or GitLab and get started.

If you make four pull requests between October 1 and October 31 to any Github hosted repository you get a Hacktoberfest T-shirt. This year I decided to take part and I already made two pull requests. My first OSS contribution I created my first pull request to an OSS project 3 years after I registered on Github. I know it can be hard to start contributing. At first I didn't think my code was good enough, then I couldn't find the right project with the right issue I could fix. One day an opportunity presented itself. At work I was using auto-parcel to generate the boilerplate required for Parcebale implementation on Android. It's a cool library based on auto-value by Google. At the time I was using version 0.3 - the version displayed in the README file on Github. A few days later while creating another value class I got an error. I googled the error and it led me to an issue on the project's Github page. The issue was closed and a new version, version 0.3.1 was released. The README file was outdated, it still pointed to the previous release containing the bug. I spent 10 minutes because of a bug that was already fixed. What a waste of time. If I wasted time chances are someone else will also run into the same problem so I decided to do something about it. Opening an issue on Github would be nice but the solution was so simple I decided to fix it myself and make a pull request. I also updated another dependency (android-apt) in the README to the latest version. The next day my pull request was accepted and it felt good. Hacktoberfest 2017 A few days after Hacktoberfest 2017 started I run into an interested project on Github - TornadoFx a Lightweight JavaFX framework for Kotlin. I like Kotlin and it's Hacktoberfest so I decided to contribute and maybe get a cool T-Shirt in the process. I noticed the project didn't have enough unit tests so I decided to write a few. I fo ## Outreachy: What It Is, How It Works, and Why It Matters DevFeed: [Outreachy: What It Is, How It Works, and Why It Matters]() Original publisher: [Read original article]() Author: Anjana Sofia Vakil (contact@anjana.dev) Published: 2016-05-23T00:00:00Z Content type: article Language: en Sources: [Mozilla Automation]() Topics: [Hacktoberfest](), [Open Source](), [rust refactoring](), [Python](), [Testing](), [The Lounge](), [Firefox](), [Puppeteer]() Tags: [foss](), [internship](), [irc](), [mozilla](), [open-source](), [outreachy](), [python](), [refactoring](), [software](), [testing]() ### AI overview The author describes starting an Outreachy internship with Mozilla and explains how the program helps people from underrepresented groups participate in free and open-source software. The article covers its remote, paid, three-month internships, mentoring, communication practices, and the author's project to test and refactor Marionette's Python test runner. ### Source excerpt Today was my first day as an Outreachy intern with Mozilla! What does that even mean? Why is it super exciting? How did I swing such a sweet gig? How will I be spending my summer non-vacation? Read on to find out! What is Outreachy? Outreachy is a fantastic initiative to get more women and members of other underrepresented groups involved in Free & Open Source Software. Through Outreachy, organizations that create open-source software (e.g. Mozilla, GNOME, Wikimedia, to name a few) take on interns to work full-time on a specific project for 3 months. There are two internship rounds each year, May-August and December-March. Interns are paid for their time, and receive guidance/supervision from an assigned mentor, usually a full-time employee of the organization who leads the given project. Oh yeah, and the whole thing is done remotely! For a lot of people (myself included) who don't/can't/won't live in a major tech hub, the opportunity to work remotely removes one of the biggest barriers to jumping in to the professional tech community. But as FOSS developers tend to be pretty distributed anyway (I think my project's team, for example, is on about 3 continents), it's relatively easy for the intern to integrate with the team. It seems that most communication takes place over IRC and, to a lesser extent, videoconferencing. What does an Outreachy intern do? Anything and everything! Each project and organization is different. But in general, interns spend their time... Coding (or not) A lot of projects involve writing code, though what that actually entails (language, framework, writing vs. refactoring, etc.) varies from organization to organization and project to project. However, there are also projects that don't involve code at all, and instead have the intern working on equally important things like design, documentation, or community management. As for me specifically, I'll be working on the project Test-driven Refactoring of Marionette's Python Test Runner. You can
