Let's talk about debugging and observability. We work with debugging all the time, but how well do we know this common practice? Observability, monitoring, and debugging at scale for your production.

In this podcast,  we are talking to some of the key people working on different IDEs, Integrated Development Environments. Those are applications that provide tools to computer programmers for software development. An IDE typically consists of at least a source code editor, build automation tools, and a debugger. Let's learn how these tools evolved, and the challenges they face to stay up-to-date with the many evolutions in Java and all other programming languages. And what we can still expect in the future!

A few weeks ago, Ted Neward published a post in which he reviewed the predictions he made one year ago and added a long list of predictions for 2023. In this Foojay Podcast episode, we talk about these predictions, and we even found an analogy between what has happened at Twitter in the last months and the history of Java!

Last month we introduced a new topic in this podcast when we visited the Manchester Java User group. That JUG already exists for nearly 10 years, so they had a lot of history to share. In this episode, we talk to the organizers of the Dubai JUG that started in May of 2022. Let’s learn what the challenges are for a new JUG, how the culture of Dubai and Hawai are alike, possible upcoming conferences, and much more

With this Foojay Podcast, we introduce a new topic: once per month, we will virtually travel to a Java User Group (JUG) to learn how they organize their events and learn from their experiences.

For this first Foojay JUG Podcast, we are flying to Manchester in the UK.
