How Open Source Influenced Traditional Product Development

André Lemos, VP of Products, iText Software

Tuesday, December 7, 2021
10:30 AM - 10:55 AM PT 
OPEN Stage

Abstract: André explores the history of open-source development and its influence on traditional product development. In turn, he also discusses how COSS products benefit from the backing of a commercial enterprise; by employing full-time developers, keeping the product’s development on the right path, and how this feeds back into the open-source community.

He also talks about how iText uses its commercial side to drive development and benefit its wider community, and how open source can benefit from competition in the marketplace.

The Evolution of Open Source into the Commercial Arena

Raf Hens, CTO, iText Software

Wednesday, December 8, 2021
12:30 PM - 12:55 PM PT 

Abstract: Raf discusses how Open Source has evolved over the years to become a force in the commercial arena. As an example, he talks about how iText began as a hobby project which transitioned into a community project, and then into a dual-licensed one.

He explores the reasons why the core iText PDF library remains open source, the differences between dual licensing and the “Open Core” model, and the importance of meeting the expectations of our development community.

Finally, he looks at the importance of structure and processes, why the “benevolent dictator” approach works in open source, and the impact of transitioning from FOSS to COSS on engineering.
