I hosted an online meetup with Elizabeth K Joseph, IBM Developer Advocate on how COBOL and open source are used in modern mainframe ecosystem. The online meetup consisted of a short presentation and Q&A session. In the first part of the meetup Elizabeth covered the following:

Elizabeth is an awesome speaker. I highly encourage you to watch the replay.

In the Q&A part, she answered the following questions (when you click on Answer you will jump to that place in the video):

Can you tell little bit more about “Master the Mainframe Program”. Can you learn a COBOL in this course? [Answer]
How many online transactions can it [mainframe] handle? [Answer]
How do you call back to a COBOL program? [Answer]
Is there access to this type of machines for developers [on the cloud]? [Answer]
Is Wazi based on zPDT? [Answer]
As a former COBOL programmer (not IBM), is there a way to retrain and find a job in the San Francisco Bay Area? [Answer]
How do you connect to back-end COBOL form front end? [Answer]
Which challenges did you face when learning about IBM Z? I was surprised to learn today you were Developer Advocate / IBM Z for only about a year; you published posts and today give this presentation. I got the impression you’ve had mainframe experience for way longer [Answer]
What are code profilers recommended for COBOL? [Answer]
Did you meet any limitations when using COBOL? I mean something you wanted to do and you couldn’t because of COBOL? [Answer]

Elizabeth also shared the following resources to help learn about COBOL and meetup slides:

This was a very fun online meetup and we will have Elizabeth back again.
