TPDP038: COBOL Development on the Mainframe

In this episode I'm joined by Elizabeth Joseph from IBM, and we discuss COBOL. I know what you're thinking. Why are we resurrecting a dinosaur of a programming technology for this podcast episode? While the programming language is one of the oldest, it is still very relevant when it comes to modern development, more particularly mainframe development. While the focus point of this episode is around COBOL, Elizabeth and I spend a lot more time discussing mainframe development and where it fits in a world where JavaScript, Python, and similar technologies are dominating.

In this episode I'm joined by repeat guest, and awesome developer, Corbin Crutchley from Unicorn Utterances. The topic of this episode is on testing, and I'm not talking about taking exams, I'm talking about writing tests in your development projects to produce much better final products. If you've ever been curious about the differences between unit tests, integration tests, end to end tests, and all of the other possible types of tests that might exist, this episode is for you. It doesn't matter if you're a new developer, a casual developer, or expert developer, knowing how to write tests will greatly benefit your career.

In this episode I'm joined by Upkar Lidder from IBM, and we're talking about modern machine learning. Do you process a large amount of data and manually make decisions on it? There's a good chance that you could be leveraging machine learning to reduce your workload and make more accurate decisions. Learn about what machine learning is, how it differs from artificial intelligence and data science, and what you need in order to be successful with it.

In this episode I'm joined by Lennart Frantzell from IBM, and we're talking about the blockchain. If you've ever been curious on what the blockchain is, why you should develop on it, or how to even develop on it, this is the episode for you. We clear the air on a lot of misconceptions that people have and show that it is more than just cryptocurrency and hype.

This episode is a continuation of the previous episode featuring Marek Sadowski from IBM. In the previous episode, Marek and I discussed the history and use-cases behind virtual machines, containers, and bare metal deployments. We briefly discussed orchestration, but ran out of time when it came to getting into the exciting topics. As part of the continuation, we jump into Kubernetes (K8s), a popular container orchestration tool, and how it differs from popular orchestration services like Red Had OpenShift. If you're looking to scale your organization, this is an episode worth listening to.

In this episode I'm joined by Marek Sadowski from IBM, and we're bringing DevOps into focus. More particularly, we're focusing on virtual machines, containers, and orchestrating them with tools like Kubernetes and RedHat OpenShift. If you've ever had to deploy an application, you've probably asked yourself, what do I choose for deployment? Do I build my own hardware, use a virtual machine, or do I look into containers? What happens when your one application turns into one hundred applications? How do you manage those applications without bringing yourself to madness? Do you choose something like Kubernetes, or do you explore a managed solution like OpenShift? This is a two part episode with this particular episode focusing on containers, virtual machines, and Kubernetes. The next episode in the series takes a spin at comparing Kubernetes to solutions like OpenShift for orchestration.

In this episode I'm joined by Corbin Crutchley, a friend and regular on the show, and we set out to talk about TypeScript and how it is used in modern development. If you've never been exposed to TypeScript, it is a strongly typed language that acts as a superset to JavaScript, but compiles to JavaScript in the end. It is a go-to technology for a lot of developers and is becoming increasingly popular every day. Corbin and I take some time to explain all of the benefits and a few of the negatives about this awesome technology in this episode of the show.

In this episode I'm joined by Adrienne Tacke, author of Coding for Kids: Python, and Alex Ziskind, owner of the NativeScripting course platform. The topic of this episode is broken into two parts. The first is around improving your skills as a developer through different education avenues such as eBooks, video courses, conferences, and other events. The three of us on the show are developers, like many of the listeners. We each have our own methods towards learning new development technologies or deepening our skills with the technologies we're already using. Some of these methods might not be obvious and it's something we want to share. The second part of the episode is around taking the developer skills that you have and then using them to teach others through writing your own eBooks or courses, and what it looks like in terms of hardware, funding, and similar.

In this episode I'm joined by Vijay Menon, organizer of the JavaScriptLA and JavaScript South Bay Meetup groups in Southern California. The topic of this episode is around the importance of being a part of a developer community and building your own if one doesn't already exist in your local area. In this episode you'll hear success stories that Vijay has had at his very large and successful developer communities and the work that is involved for building and managing your own on Meetup.com.

In this episode I'm joined by Corbin Crutchley, a seasoned JavaScript developer with extensive knowledge of various frameworks such as Vue.js, Angular, and React.js. Corbin also operates his own development blog, Unicorn Utterances. The topic of this episode is around asynchronous development using JavaScript and no particular framework. If you're coming from other programming languages, the concept of promises, callbacks, async / await, and similar all might seem daunting when it comes to working with remote web services or even resource intensive proccesses. Corbin and I shed some light into the world of doing things asynchronously and hopefully clear things up and even make the concepts easier to wrap your head around.
