What do you do next when you have over 150 patents to your name? Write a book, of course! Lin Sun is a Senior Technical Staff Member and Master Inventor at IBM, where she has spent the past 14 years doing software engineering in areas including cloud and open technologies. She has worked on the Istio service mesh since 2017, and is on the Istio steering and technical oversight committees. Lin joins Adam and Craig to discuss invention, making Istio easier to use, and how being a mother has impacted both.
