What we're about

Welcome to the Chicago Kotlin Users group! We are a group of lovely people interested in this fun and new language that is quickly winning popularity on the JVM and spreading to JS and Native. Come join us and learn more about this neat, pragmatic language, the ecosystem surrounding it and what Kotlin can do for you! We hope to have interesting presenters/talks and presentations once a month. If you have a topic you'd like to hear about, let us know! If you want to present something, get in touch!

Look forward to meeting you soon!

Kotlin Night with Thomas Nield + Victoria Gonda

Pivotal Labs

Come join Chicago Kotlin User Group for a Kotlin Night with Thomas Nield and Victoria Gonda! Doors open at 5:00, and the talks will begin 5:30. Thomas Nield - The Many Types of "AI" As programmers, we love solving problems. However, sometimes we need more than programmer grit to solve many problems with no easy answer. Suppose you need to tightly schedule 190 classes in 20 classrooms, with different class durations, recurrences, and constraints throughout the week? What about minimizing the operating cost of a train schedule while maintaining a steady movement of passengers? How about identifying objects in images? Or simply solving a Sudoku? Victoria Gonda - "Transforming your Tests with Kotlin" We know we should write tests, and we know that Kotlin gives us some nice features to use in our code, so how can we put these two together? There are some really great ways that Kotlin is being used in test writing, and we'll look at a number of them. This will include features such as higher order functions and escaping back-ticks and how they can make your tests more expressive. We'll also look at some testing libraries that take advantage of Kotlin's features. At the end of this talk you'll walk away with an understanding of how you can use Kotlin to make your tests more enjoyable.

Kotlin + Android: Coroutine-first Android architecture w/ Rick Busarow @ GrubHub

This month we have a very special meetup! We will be joining forces with Android Listener for a great night of Kotlin and Android at the GrubHub office. Rick Busarow - Coroutine-first Android architecture Coroutines are the new hot stuff, and right now they’re being added to lots of libraries. But what if you don’t want to use an alpha01 in production code? What can coroutines do on their own, right now? In this talk, we’ll discuss the power behind structured concurrency and how we can use it to make our entire stack lifecycle-aware. We’ll look at examples of how to turn any callback or long-running code into a coroutine, and we’ll go over when and how to use Channels to handle hot streams of data without leaking. Finally, and most importantly, we’ll see how we can use these tools to inform our application architecture, so that we can quickly write maintainable and testable features. Android Listener normally meets on the 3rd Wednesday of each month. More details can be found at https://www.meetup.com/AndroidListener-Chicago/
