| Fosstars – A Rating Approach to Open Source Components | 31 Mar 2021 | 00:33:58 | |
In this episode Karsten Hohage talks with our guests Michael Bernhardt and Artem Smotrakov about Fosstars, a java-based framework that allows you to define various ratings for open source projects. The name “Fosstars” is a combination of “FOSS” for “Free and Open Source Software” and the concept of rating products or services with “stars”. It helps software engineers and architects to quickly assess various aspects of open source components, such as their security, maturity, etc. It is often difficult to analyze the actual code of all the open source components in an application and compare them with respect to various aspects. To make it easier, Fosstars offers ratings that are based on publicly available information about the projects, such as adopted security tools and best practices, activity of the community, and many more. Thus, Fosstars is a project, that deals with other open source projects, making the natural approach to it – guess what – open source! Guests:Michael Bernhardt works as a program manager for SAP’s Open Source Security Strategy and DevSecOps lead in SAP’s corporate security organization.

| Clean ABAP – Best Practices for Effective ABAP Code, Straight from the Expert | 24 Feb 2021 | 00:36:34 | |
In this episode Karsten Hohage talks with our guests Klaus Häuptle and Florian Hoffmann about the importance of having a readable and maintainable codebase to ensure sustainable development. Klaus and Florian started an internal repository with best practices for maintainable and readable ABAP code. Through info sessions with many hundreds of participants, intense discussions, and great contributions, SAP colleagues helped turn this into a treasure trove for modern ABAP’ers. Many developers asked if this would become available as a book, and if they would be allowed to share it with customers and partners. They soon realized that this initiative gained its early drive from its community and needed to remain part of that community. Thus, they opened it to contributions from inside and outside of SAP, hoping that this repository would help developers worldwide to make their ABAP code a little cleaner. In late 2020, they published the book “Clean ABAP” to help individual developers, teams, and entire organizations with learning and implementing clean ABAP. Guests:Klaus Häuptle is a software engineer who worked on different products and technologies in the areas of governance, risk, and compliance and supply chain management. During his career he has also been a trainer, coach, and product owner for agile software engineering.

| Project "Gardener" – Managing Kubernetes at Scale | 09 Dec 2020 | 00:35:40 | |
In this episode Karsten Hohage talks with our guests Vasu Chandrasekhara and Tim Usner about project Gardener. Today, Kubernetes is the natural choice for running software in the cloud. More and more developers and corporations are in the process of containerizing their applications, and many of them are adopting Kubernetes for automated deployments of their cloud native workloads. There are many open source tools which help creating and updating single Kubernetes clusters. However, the more clusters you need and the more infrastructures need to be supported, the harder it becomes to operate, monitor, manage, and keep all of them up-to-date. And that is exactly what project Gardener focuses on. Tim Usner Tim Usner joined SAP after studies in information technology. He started his career as a business software developer and later switched to the Gardener project in 2018. Besides his contributions to core components of Gardener, he has advocated the project at different events and supported development teams with their transition to Gardener and Kubernetes.

| Outbound Process Made Easy – SAP’s Process and Tooling | 25 Nov 2020 | 00:32:38 | |
In this episode Karsten Hohage talks with our guest Fabienne Haag about the Open Source Outbound Process at SAP and how it was implemented. During the last few years, SAP has been actively initiating and maintaining its own open source projects. Many SAP employees contribute to these projects or to completely different ones. This led to the need to have a simple and transparent process in place. The new Open Source Outbound Process enables developers to easily and quickly start new open source projects and contribute to existing projects – both in a compliant and secure manner. The entire approval workflow is executed in Enterprise GitHub, which is close to the developer community and gives them an easy way to manage their open source contribution requests. Guest:Fabienne Haag Fabienne Haag works at SAP Global Licensing. She is responsible for compliance requirements of the usage of open source components in SAP products. In addition, she is deeply involved in the open source outbound process. LinkedIn: https://www.linkedin.com/in/fabienne-haag-597a01173/ Show Notes:

| InnerSource Rocks | 11 Nov 2020 | 00:37:19 | |
In this episode Karsten Hohage talks with our guest Michael Picht about InnerSource at SAP and why it should be the default development model at SAP. InnerSource is the practice of applying methodologies and best practices from open source projects to in-house software development. In an InnerSource approach, projects are open for contributions from other teams. This implies that they accept and build on these contributions – just as an open source project would. The major difference are the boundaries: the community is in-house, it only consists of colleagues, and the codebase cannot be accessed from outside of the company. By applying InnerSource in an enterprise software development context, you can increase quality, speed, collaboration, and developer joy. Moreover, especially large development organizations can break silos between different teams and encourage developers to expand their skills or use them to support cross-team projects.

| Corona-Warn-App: Behind the Scenes | 28 Oct 2020 | 00:39:24 | |
SAP collaborated very closely with the German Government, Robert Koch Institute, Deutsche Telekom, and other partners to develop the Corona-Warn-App in an open source approach. The app warns the users if they have been in close proximity to someone diagnosed with COVID-19. This helps to trace chains of infection and provides guidance to people who have tested positive. The decentralized approach and pseudonymization ensure the highest level of security and data privacy. In this episode, our host Karsten Hohage talks to one of the community managers of the open source project, that was established to develop the Corona-Warn-App. If you want to learn more about The Corona-Warn-App go to: https://www.coronawarn.app/en/ or GitHub: https://github.com/corona-warn-app and share your ideas with us: ospo@sap.com Guest:Sebastian Wolf Sebastian is a development architect and works for the SAP OSPO since the beginning of 2020. He first joined SAP already back in 2003 as a student and has since worked in several development positions such as SAP SRM, ABAP Development Tools, the SAP Community Network and Central Architecture. He was engaged from the very beginning at the Corona-Warn-App project as a community manager. GitHub: https://github.com/Wunderfitz

| Open Source at SAP | 09 Oct 2020 | 00:43:46 | |
SAP is the 9th largest commercial contributor to open source projects. Mostly known for proprietary software, almost all of SAP’s solutions touch open source in one way or another. The Open Source Program Office, founded in April 2018, has the mission to nurture and support the open source approach to software development inside and outside of SAP. Listen to our host Karsten Hohage and our guest Peter Giese why Open Source is important in a global enterprise, why it is a triple win for customers, developers and SAP, and why you need an Open Source Program Office. These and more questions will be answered in this episode. Peter Giese Peter focuses on refining SAP’s open source strategy, developing new tools and approaches for managing open source at scale and on further promoting InnerSource at SAP. Since joining SAP in 1996, Peter has held several managerial and executive positions in application and technology development. Before joining SAP, Peter worked as a researcher at Fraunhofer Institute for Experimental Software Engineering (IESE) and as a development manager at Kiefer & Veittinger Software Unternehmensberatung GmbH. Peter holds an M.Sc. degree in computer science from Kaiserslautern University of Technology. Show Notes:
