Contribution Track

As part of the Contribution Track, you will contribute code to our partner open source software (OSS) projects. You will work in groups, where you’ll have opportunities to learn from one another, as well as from experienced mentors, there to guide and help you make your OSS contribution.

Additionally, we have a “Choose your own adventure” option, where you have the opportunity to contribute code to projects led by women maintainers or to just any project in the OSS community.

New to Open Source? Don’t worry! You will not be alone; We will guide you through finding issues that are suited for your skill level and there will be mentors ready to help you.

Partner Projects


Description Maintainer(s)
A11y track is a new OSD initiative to make open source projects more accessible for contributors and users by breaking down language barriers and reducing the number of accessibility violations in applications and tooling.

A11y project participants will:

- Use WCAG and ATAG standards to fix accessibility, localization and internationalization bugs
- Test using assistive technology or auditing tools (such as AXE) to find accessibility violations within the project
- Add onboarding support for additional languages

Eclipse AQAvit

Description Maintainer(s)
AQAvit is the quality and runtime branding evaluation project for Java SE runtimes and associated technology. During a release it takes a functionally complete Java runtime and ensures that all the additional qualities are present that make it suitable for production use. These quality criteria include good performance, exceptional security, resilience and endurance, and the ability to pass a wide variety of application test suites. In addition to verifying that functionally complete runtimes are release ready, the AQA tests may also serve to verify new functionality during runtime development.

Hyperledger is an open source community focused on developing a suite of stable frameworks, tools and libraries for enterprise-grade blockchain deployments. It serves as a neutral home for various distributed ledger frameworks including Hyperledger Besu, Hyperledger Cactus, Hyperledger Indy, and Hyperledger FireFly.  
Hyperledger Besu: Hyperledger Besu is an Ethereum client designed to be enterprise-friendly for both public and private permissioned network use cases. It can also be ran on test networks such as Rinkeby, Ropsten, and Görli. Hyperledger Besu includes several consensus algorithms including PoW, and PoA (IBFT, IBFT 2.0, Etherhash, and Clique). Its comprehensive permissioning schemes are designed specifically for use in a consortium environment. Grace Hartley, and Justin Florentine
Hyperledger Indy: Distributed ledger software. Hyperledger Indy provides tools, libraries, and reusable components for providing digital identities rooted on blockchains or other distributed ledgers so that they are interoperable across administrative domains, applications, and any other silo. Indy is interoperable with other blockchains or can be used standalone powering the decentralization of identity. Renata Toktar
Hyperledger Cactus: Hyperledger Cactus is a plugin based framework which aims to provide developers with an abstraction over protocol specific implementations, and enabling interoperability. This enables solutions to more easily adapt to new protocols, and make transactions involving multiple public and/or permissioned ledgers. Peter Somogyvar, and Tracy Kuhrt
Hyperledger FireFly: FireFly is a multiparty system for enterprise data flows, powered by blockchain. It solves all of the layers of complexity that sit between the low level blockchain and high level business processes and user interfaces. FireFly enables developers to build blockchain apps for enterprise radically faster by allowing them to focus on business logic instead of infrastructure.

During this session, you will contribute to openSUSE, a Linux based open-source project which provides Linux distributions as the rolling release openSUSE Tumbleweed, the stable release openSUSE Leap and for Kubernetes openSUSE Kubic. Additionally, there are multiple sub-projects with expanding software. The openSUSE project supports the hardware architectures x86, arm, PowerPC and the mainframe architecture s390x (IBM Z). Participants in this Open Source Day project will learn about multiple ways of openSUSE contributions and how to become an openSUSE Member. In addition, they receive an insight how to enable application software as Container Images or packages. Do you want to help make a contribution? Then go to an openSUSE Mentor and you will be allowed to receive your first openSUSE experience on a mainframe with the name LinuxONE (outside of your pc hardware experience). We support you during your first steps with contributions to Linux. We are open for all questions, too. Sarah Julia Kriesch, and Christian Boltz

Description Maintainer(s)
Akri exposes IoT devices (such as IP cameras and USB devices) as resources in a Kubernetes cluster. Akri continually detects nodes that have access to these devices and schedules workloads based on them. A user simply installs Akri to their cluster, and the work of discovering, using, and monitoring the availability of the devices is abstracted away. Simply put: you name it, Akri finds it, you use it. Kate Goldenring, Roaa Sakr

Spring Cloud provides tools for developers to quickly build some of the common patterns in distributed systems (e.g. configuration management, service discovery, circuit breakers, intelligent routing, micro-proxy, control bus, one-time tokens, global locks, leadership election, distributed sessions, cluster state). Coordination of distributed systems leads to boiler plate patterns, and using Spring Cloud developers can quickly stand up services and applications that implement those patterns. They will work well in any distributed environment, including the developer’s own laptop, bare metal data centres, and managed platforms such as Cloud Foundry. Olga Maciaszek-Sharma
