Code PaLOUsa 2021

August 18, 2021 - August 20, 2021

Codepalousa is a multi-day software development conference designed to cover all aspects of software development regardless of technology stack. The conference features presentations from well-known professionals in the software development community and virtual booths where leading software development companies come to interact with attendees to show off their latest wares. Open Mainframe Project Ambassadors Joe Winchester, Jessielaine Punongbayan, Richelle Anne Craw as well as  John Mertic, Open Mainframe Project Director, will be presenting several sessions including:

Joe Winchester, Wowee it’s Zowe – how the mainframe got its groove again – Thursday, August 19 at 8:30 am EDT

The mainframe is often viewed as a legacy 65 year old computing platform operated by grey (or zero) haired developers typing 8 letter commands into green screens. This talk myth busts that stereotype and discusses the growth of the mainframe in today’s hybrid computing world, especially around the Linux Foundation’s Zowe project. This provides a command line interface, a VS Code extension, academic initiative training courses, and is a bridge to modern tech stacks around Jenkins, Node.js, Swift, Golang and more.

Jessielaine Punongbayan and Richelle Anne Craw: VS Code for Green Screen Developers.  Thursday August 19th 9:45am EST

Mainframe modernization is an unavoidable topic for every developer these days, whether your tool is the traditional green screen or another IDE. How does the coding experience differ between the two? In this session, we will showcase a side-by-side comparison on these development environments, based on our experience using both. We will also dig into what the different mainframe VSCode extensions are, how to take advantage of automation in VS Code, and how to integrate product-specific components and other open source tools in the developer workflow.

Jessielaine Punongbayan and Richelle Anne Craw: COBOL Coding in the Cloud.  Friday August 20th 8:30am EST

How do you imagine coding in COBOL? Join this session as we give you a glimpse of our day as COBOL developers working with Eclipse Che4z, a mainframe development tool that blurs the lines between mainframe and distributed environments. Come and hear about the tips and tricks we learned first-hand; the technologies involved; and the challenges we experienced, switching from traditional green screen development to Cloud IDEs. We will discuss the benefits of using a cloud managed mainframe stack and how quickly we can provision our development environment and get started with team collaboration.

John Mertic and Joe Winchester: Who said you can’t teach an old dog new tricks? – Friday, August 20 at 9:45 am EST 

The Mainframe computer is over 65 years old, and has a dual personality of either being viewed as a proprietary thing of the past or else a hidden closed locked down machine as espoused in Hollywood movie plots. The truth is neither, and a huge amount of mainframe computing workload today comes from open source tooling. This talks show the use of Linux Foundation tools, especially Zowe, Jenkins, modern tools such as VS Code, IntelliJ, modern languages like Node.js, Java, Swift, Golang, and more. A lot of the mainframe’s growth comes not from tech, but from its ability to build communities and academic learning initiatives. From what was once a platform businesses were leaving due to stagnation, this talk shows the turnaround and the important lessons to be learned that apply to any technology wishing to survive beyond its 50th birthday.
