The Values of Open Source

source{d} 's mission is to improve Developer Experience with Machine Learning. This means we retrieve analyze large datasets of source code, with source code, to help others write code.

Code, code, code ... and all fo this code is open source!

In this talk we cover how we benefit from the existing Open Source community, while contributing back to it and protecting our Intellectual Property.

1. The values and challenges of Open Source at source{d}
2. VP of Developer Relations francesc@sourced.tech @francesc campoy
3. Agenda source{d} and Open Source Our MIssion - ML on Code - Code as Data Open Core Open Source Benefitting from Open Source Cooperation Contributions Protecting with Open Source Copyleft Licenses MIT, Apache v2, GPLs Q&A
4. source{d} and Open Source
5. source{d} and Open Source our mission Improving the Developer Experience through Machine Learning
6. source{d} and Open Source our mission Requires large datasets Results in trained models Examples: - Bug prediction - Automated Code Review ML on Code Large software repositories Source code *and* history of revisions Extracting metrics - Business Intelligence SQL, GraphQL, REST interfaces Code as Data
7. ML on Code Code as Data Code
8. source{d} and Open Source Open Core Open Source Core Tools & Services
