What we're about

The Chicago Java User’s Group is here to help the Java Professional. We want to make Chicago the ‘best’ place to be a Java developer, by offering a support network that allows each individual Java developer to grow! Its only purpose is to serve its community by focusing on three areas: - Learning about the Java Craft - Making a Difference in the Java Community - Growing as a Java Professional
Please join our communication channel on Discord:  https://discord.gg/U25g437
Please find our session recordings on YouTube:  https://www.youtube.com/user/CJUGVideos
We would like to invite recruiters, staffers, head hunters, and all human resources personnel who are looking for Java talents in our meetup group, to join our LinkedIn group.

We are now on Mastodon! Please follow us: @ChicagoJUG@foojay.social

If you are interested in presenting, please submit your proposals to us via e-mail at present@cjug.org.

Developer Productivity Engineering - The Next Big Things in Software Development

Just two years ago, IDC accurately predicted that by now 65% of the global GDP will have been digitally transformed. Two-thirds of the products and services that you pay for are driven by software, and the quality, cost and time to market of your software products determine the fate of your business. There has never been a more important time to foster developer productivity, but many of our methods have not evolved.

In this keynote style talk you will learn why DPE is one of the most important developments in the software engineering world since the introduction of Agile and DevOps concepts and tools. DPE is a new software development practice that uses acceleration technologies to speed up the software build and test process and data analytics to improve developer efficiencies by as much as 10x. The ultimate aim is to achieve faster feedback cycles, more reliable and actionable data, and a highly satisfying developer experience.

*** Second Talk (Justin Reock and Josh Long) ***

Kotlin, Gradle, and Spring - The Recipe for Developer Joy

Hans Dockter invented the Gradle Build Tool in 2008 out of a deep sense of frustration with low-productivity environments. Today, Gradle is one of the most popular build tools for the JVM and extended ecosystem, in many ways because it prioritizes developer experience and respects developer’s time. It was only logical then for Gradle to go on to embrace the vision and mission of the Spring and Kotlin developer communities since both solutions exist to help developers become more productive.

In this session, you’ll learn about the emerging practice of Developer Productivity Engineering (DPE), a pragmatically idealistic practice that merges developer happiness with developer productivity. You’ll learn about the powerful relationship between Kotlin, Spring, and Gradle, including a primer on the Kotlin DSL for Gradle Build scripts, and you’ll get a chance to explore how the Kotlin and Spring developer communities have used DPE to improve the experience of contributing code to their respective projects. Finally, you’ll get a glimpse of our future strategy together, building on milestones such as Gradle becoming default in Spring Initializr.
