This is a 4-day industry geek-out with a fantastic list of presentations https://osselc21.sched.com/. I like conferences sometimes and picking and choosing what I want to learn about. Dig it:
How to Talk About your Open Source Project so People Get It - Emily Omier, Emily Omier Consulting
Are We Forever Doomed to Software Supply Chain Security? - Liran Tal, Snyk
Building Robotics Applications at Scale using Open Source from Zero to Hero - Alex Coqueiro, AWS
Evolving FOSSology Ecosystem - Anupam Ghosh & Gaurav Mishra, Siemens AG
A Solution to the Tension Between Worker Shortage and the Hungry Hungry Developer - Jordan Hewitt, Damn Good Technology
---those are just a handful I would see...if I had the time and money🙂
