  subject: 'Troubled Waters: Bridging platform-native SDKs with Kotlin Multiplatform'
  url: https://www.sf.droidcon.com/schedule
  description:
    __cdata: >

      <p>One of the most valuable features of Kotlin Multiplatform is being
      able to interop with existing platform-native SDKs from Kotlin code.
      This allows you to take existing code from Android and iOS, and rather
      than "rewrite it", simply create a common Kotlin SDK surface that
      delegates to the platform-native SDK code. Then you can call
      everything from Kotlin!<p>

      <p>This is not always so easy. There are a number of considerations
      you should keep in mind when planning your shared code utopian vision.
      In this talk we'll discuss:

      <p>* When to bridge and when to rewrite (if possible)

      * Interfaces or expect/actual? (Almost always interfaces, but no
      spoilers here)

      * cinterop basics

      * Packaging and deployment related topics.<p>

      <p>Some of this ground was covered at Droidcon SF 2019, but we've
      learned and refined so, so much since then!<p>

    Kotlin Multiplatform Mobile in production: key takeaways from developing

  description:
    __cdata: >

      <p>Kotlin Multiplatform Mobile is a young promising technology, but is
      it there to stay? And is it worth trying out? This talk is based on
      the experience of developing two very different cross-platform apps
      with KMM. The goal of this talk is to introduce KMM, discuss the
      pitfalls that a new KMM developer may encounter and share some
      valuable tips that were collected along the way of KMM development:
      from preferable app architecture to team requirements.<p>

      <p>When writing more powerful abstractions with Kotlin it becomes
      necessary to have a strong grasp of how to use generics. This talk
      covers a variety of concepts surrounding generic types & type
      parameters.

      Key points:

      * variance (covariance, contravariance, invariance)

      * type projection (+star projection, aka wildcard)

      * type constraints

      * reification (with inline modifier)<p>

      from Java to Kotlin. Based on real-world experience, code statistics,
      and many code samples, light will be shed on questions like ‘What were
      the benefits and drawbacks?’, ‘How did we approach it?’ …and most of
      all: ‘Was it worth it and why?’ At the end of this talk, you know in
      detail the differences between Java and Kotlin. You have learned what
      to expect when embracing Kotlin and which best practices you can
      apply, providing you with the information and tools to evaluate
      whether Kotlin is worth a try.<p>

      background, these details are often missing background knowledge that
      everybody learns “the hard way”. Static or dynamic frameworks?
      Linking? Cocoapods vs SPM? This talk is an introduction to what the
      Kotlin compiler actually produces, what choices you’ll need to make,
      and things you may want to consider before attempting to integrate
      Kotlin shared-native code into a production iOS environment.<p>

      <p>Are you a Kotlin expert? Or maybe you have never worked with it
      before?  Either way, there's a lot for you to learn because Kotlin
      isn't just a fancy, new Java syntax, but another way of programming! 
      Come with me on a quick journey comparing Java's beloved design
      patterns and how they were simplified or even replaced by Kotlin
      quirks and features.  Amongst those patterns are Singleton, Factory,
      Builder, Util and more. Even if you're not interested in patterns, you
      can still learn about the features of Kotlin like extension properties
      or delegates. There's something new for everyone.<p>

      <p>State Flows and Shared Flows were introduced to broadcast events to
      multiple consumers with coroutines. You might have been using
      Broadcast Channels and are starting to migrate to Shared Flows. Or,
      you might be converting your RxJava code to Flows.<p>

      <p>We’ll dive deep into the Shared & State Flow APIs. A Shared Flow
      provides you with ability to replay and cache events. How does it
      compare and map to existing RxJava constructs like publisher subjects?
      Or, how is it different from a Broadcast Channel? How do you handle
      back pressure? We’ll look into simple to complex use cases for
      migrating to Shared Flows and explore these questions in detail.<p>

      <p>By the end of this talk, you’ll have a good starting point to begin
      to migrate to State Flows and Shared Flows.<p>

      <p>A little guide on how to convince management to try out new

      it'll bring your team to the next level. You see clear advantages, but
      others are not quite there yet. In this talk, I'll describe the ways
      we found to get Kotlin inside ING, one of the largest European bank.
      We'll look into simple ways to convince your colleagues, your
      management and make it a success for everyone! Those days, there are
      so many tools to improve one developer's workflow that it's hard to
      make a choice, and sometimes convince others. Languages, frameworks,
      tooling, paradigms, there is so much to try and not everything can be
      a benefit. In this talk, we will have a look at why Kotlin probably
      makes a lot of sense for your team. We'll have a quick glance at some
      language features, the ecosystem and the community as well. But we'll
      mostly have a look at various techniques to make Kotlin (or, for that

      <p>After trying Kotlin years ago I quickly realized that you can do a
      lot more with much less code. It hits the right balance of language
      features and complexity, so that a lot can be achieved without any
      frameworks or libraries at all. However, because of good Java-interop,
      people still use many server frameworks and libraries that are written
      in Java and for Java. These contain lots of complex code, many
      dependencies waiting to prove vulnerable (like log4j) and other
      unnecessary bloat. Moreover, Kotlin type system is stronger than
      Java’s and thus many modern patterns that Java developers use seem
      unnecessary when writing in Kotlin.<p>

      With irregularities. With words having different meanings in different
      contexts. The rise of computers has brought us strictly defined
      programming languages that conflict with the, often loosely defined,
      human language. A translation layer is needed. I want to explore how
      we can use Kotlin to create such a translation within our bounded
      contexts and how we can use grammar to define our domains.<p>

      <p>Let’s face it, ui testing is probably not on top of every

      development process, it can be a tedious and monotonous job.<p>

      <p>This talk describes CTW’s effort to make writing test cases more
      efficient, safe, and expressive by leveraging Kotlin-specific features
      such as function types with receivers, extension and infix
      functions.<p>

      <p>We’ll present a lightweight and type safe Kotlin DSL for ui testing
      that is being used as an alternative to frameworks such as Cucumber,
      while still achieving highly readable test cases directly in Kotlin
      code. We’ll also show how this approach can reduce code duplication,
      speedup writing test cases and improve productivity by building a
      repository of reusable actions and assertions that can take advantage
      of syntax autocompletion provided by the IDE. We’ll even get our feet
      wet with popular testing frameworks Espresso and UiAutomator and see
      how we're able to completely abstract away these implementations

      different it is from regular functions. We'll then do a postmortem of
      few default functions offered by Kotlin OOTB to grasp the basics. Then
      we'll cover something a bit intermediate - composing our own functions
      with some aesthetics (demo, yes!) with examples to also some advanced
      concepts like Currying. Finally, we'll end the talk with small quiz
      like for audience to find pure and impure functions written in

      <p>How to verify your Kotlin project in a Kotlin way? I am talking
      about test coverage and about style linter. Wouldn’t it be great if we
      can really use Kotlin in the full spectrum and use tools that support
      those features?<p>

      <p>Of course, we would also like to check our code with a linter. In
      Java we have multiple ways to do that, but with the specific Kotlin
      format, we are in need of a new linter and formatter. Ktlint (spoken
      as kitty-lint, for the cat-lovers among us) is the perfect plugin to
      fit your needs.<p>

      <p>Most of us will know or even use test coverage engines like Jacoco
      or IntelliJ. An advantage of this is that it’s well known and
      considerably solid. The disadvantage is that it doesn’t support all
      Kotlin features, like a Kotlin directory structure. Because of that
      you have to choose to OR don’t use the Kotlin directory structure, OR
      pick a new test coverage engine. This is where Kover comes in.<p>

      <pIn this talk I will go over both plugins to see what the advantages
      are, how to configure them, and to determine which child-diseases are
      still there.<p>

      <p>A CS degree is not a requirement for software developer roles. Nor

      of thought leads to better software, after all. Still, there are some
      super useful CS fundamentals that will make you a better programmer,
      but that you may not pick up on the job.<p>

      <p>This talk gives an overview of some of these fundamentals, such as
      De Morgan's Laws, the Big O notation, and how algorithm complexity
      informs whether you should use an ArrayList or something else. It also

      rapidement des applications en ligne de commandes (CLI) pour les
      applications basées sur la JVM<p>

      <p>Durant cette session, nous allons regarder comment créer un projet,
      créer une CLI légère et facile à utiliser pour notre utilisateur, et
      la packager proprement pour faciliter son utilisation.<p>

      <p>Cette session est séparée en trois parties : une introduction au
      sujet, suivi du live coding incrémental d'une application, et un tiers
      consacré aux bonnes pratiques pour la création d'applications en ligne
      de commande en Kotlin.<p>

      <p>picoCLI brille pour de multiple raisons, que nous allons voir
      ensemble. Documentation, compilation native via GraalVM, où encore
      support de Kotlin, parfait pour créer des lignes de commandes très
      rapides et efficaces!<p>

      <p>À la fin du talk, les participants auront une connaissance de base
      de la librairie et de son utilisation, et devraient avoir une idée
      concrète de la valeur qu'elle peut leur apporter dans leur
      quotidien.<p>

      making your apps reactive is currently the best way to do it! In this
      session we will dive deeper and see how to create extremely performant
      reactive microservices with Helidon “SE” flavor. We’ll explore its
      Reactive APIs, asynchronous DB access, and reactive Web-Client. Since
      Helidon has its own powerful Reactive Engine, we’ll learn how to get
      the most requests served in async operations and Messaging. And of
      course, all of this written in Kotlin! Welcome to the Danger Zone!<p>

      <p>It's easy to start using Kotlin — it's like Java, so your

      However, to take full advantage of the language, learning Kotlin best
      practices is a must. Kotlin provides a number of features for writing
      concise and readable code. In this session, we'll take a look at
      Kotlin features that make the programs look beautiful and more

      <p>A little guide on how to convince management to try out new
      technologies!<p>

      <p>For you it's obvious, Kotlin is the next big thing and it'll bring
      your team to the next level. You see clear advantages, but others are
      not quite there yet. In this talk, I'll describe the ways we found to
      get Kotlin inside ING, one of the largest European bank. We'll look
      into simple ways to convince your colleagues, your management and make
      it a success for everyone!<p>

      <p>Those days, there are so many tools to improve one developer's
      workflow that it's hard to make a choice, and sometimes convince
      others. Languages, frameworks, tooling, paradigms, there is so much to
      try and not everything can be a benefit.<p>

      <p>In this talk, we will have a look at why Kotlin probably makes a
      lot of sense for your team. We'll have a quick glance at some language
      features, the ecosystem and the community as well.<p>

      <p>But we'll mostly have a look at various techniques to make Kotlin
      (or for that matter, any other kind of proposal) a convincing user
      case for your team. Finding your heroes, making small experiments,
      using external influence, building in public, defusing possible
      worries, there are many ways to go about it!<p>

      <p>By the end of this talk, you will have extra information on why
      Kotlin can be useful for you (or not); and be equipped with strategies
      to help convince others as well.<p>

      <p>In 2021 Kotlin turned 10 and the team delivered 2 major releases
      (1.5.0 and 1.6.0) and a few minors. The main themes of those releases
      were Java interoperability and consistency of the language features.
      Meanwhile, Kotlin/JS has been promoted to Beta and KMM is on its path
      to reaching Beta status as well. However, one long-running project in
      Kotlin is the development of the new compiler, K2, which should set a
      solid foundation for the language and the ecosystem for the years
      ahead.<p>

      <p>This session is an overview of the latest developments in Kotlin:
      the language, tools, compiler, and the ecosystem around it. We're also
      going to take a look at Kotlin's roadmap to see where are we heading.

  description:
    __cdata: >

      <p>Dependency Injection is a complicated topic, and when used in a
      project that compiles to multiple targets through different compilers
      & runtimes, it can lead to serious headaches. However, the Inversion
      of Control pattern brings a lot of architecture features and
      safety.<p>

      <p>In this talk, we will see how to use all the power of Kodein-DI, a
      popular dependency injection library that works everywhere Kotlin can
      compile to, in a mobile multi-platform project targeting Android, iOS
      and the mobile Web.<p>

      <p>We will start by using the dependency injection pattern to abstract
      and test the behavior of multi-platform business modules. We will then
      see how to debug common dependency management errors.<p>

      <p>Finally, we will enhance our common code using advanced features of
      Kodein-DI such as set bindings, lazy access, context, and scopes.<p>

      structured logging and automation capabilities.<p>

      <p>kalasim is designed for simulation practitioners, process analysts
      and industrial engineers, who need to go beyond the limitations of
      existing simulation tools to model and optimize their
      business-critical use-cases. In contrast to many other simulation
      tools, kalasim is neither low-code nor no-code. It is code-first to
      enable change tracking, scaling, refactoring, CI/CD, unit-tests, and
      the rest of the gang that makes simulation development fun.<p>

      <p>In the talk, we will learn about its core concepts and study
      several examples from different application domains.<p>

      and Kotlin! Especially in the power that Kotlin has to run long
      operations and the power to perform some calculations like computing
      min, max, an average of numbers stored in a list! - from sumOf {} to
      multi-dimensional arrays to charts!<p>

      <p>picoCLI is a small library that can be used to create JVM based
      command line interface applications. Within 30 minutes, we'll look at
      how to setup a project, create a small application and package it for
      others to use.<p>

      <p>picoCLI is a small library that can be used to create JVM based
      command line interface applications.<p>

      <p>Within 30 minutes, we'll look at how to setup a project, create a
      small application and package it for others to use.<p>

      <p>picoCLI is nice for several reasons : CLIs are a great way to
      automate some commands we run every day. And because it supports Java
      and Kotlin, we can keep using our main language of choice rather than
      having to dive into bash or node. Finally, pico applications can be
      turned into native images using GraalVM, which allows for a nice end
      user experience.<p>

      <p>By the end of this talk, you'll have a basic knowledge of what
      picoCLI can do, how to set it up and hopefully ideas of use cases to
      run it with!<p>

      <p>This is a byte size presentation so it'll have to go fast!<p>

      <p>I'll introduce the project in 5 minutes.

      Then jump into a starter project and the basic features of the library
      around. We will compile and test it live. - 20 minutes

      Finally, we will look into some of the advanced features, and check at
      packaging options for end users - 5 minutes<p>

      <p>KSP (Kotlin Symbol Processing) is an API from Google for writing
      Kotlin compiler plugins. Using KSP we can write annotation processors
      to reduce boilerplate and solve cross-cutting concerns. Also KSP is
      more effective than KAPT. Among the advantages of using it is the
      support of Kotlin Multiplatform. Another way to optimize common code
      is to use Kotlin plugins. In my talk I would to like to show some
      samples how to use own plugins and KSP processing in Kotlin
      Multiplatform app supporting both iOS and Android.<p>

      might be interested to know that there’s now another language, even
      more concise than C#, that will open up a world of possibilities for
      you to leverage the JVM. The JVM or Java ecosystem is a vibrant and
      innovative platform, and many of the libraries and frameworks we see
      in .NET have originated in Java. In this session we’ll give an
      introduction to Kotlin and the JVM from the perspective of a .NET

      <p>В этом докладе мы будем говорить про KMath
      (https://github.com/mipt-npm/kmath) и не только. Вместе с Александром
      мы рассмотрим разные подходы к математическим API и их реализациям на
      разных языках программирования (Python, C++, Julia, Java и Kotlin).
      Также поговорим о том, почему сложно сделать математику одновременно
      удобной и быстрой. Детально разберем проблему боксинга.<p>

      <p>Вы увидите, каким образом контекстно-ориентированный подход в
      Kotlin помогает решить не только проблему баланса между скоростью и
      удобством, но и позволяет сделать математические библиотеки
      модульными, и обеспечить их совместимость с высокопроизводительными
      платформными библиотеками.<p>

      <p>В заключение поговорим о том, есть ли будущее у математических
      библиотек за пределами C++ (и не только в Kotlin).<p>

      <p>На проекте, использующим Kotlin, хочется работать с Kotlin-first
      библиотеками. Например, хочется вместо Jackson использовать
      kotlinx.serialization. К сожалению, перевести существующий проект на
      любимые технологии не всегда возможно из-за разницы в подходах или
      отсутствии фич. Например, global naming strategy.

      <p>Можно ли обойти ограничения библиотеки и добавить недостающее?
      Можно! С помощью Arrow Meta.

      <p>Arrow Meta — это библиотека, позволяющая писать плагины для
      компилятора, линтеры и другие преобразователи исходного кода.

      <p>В данном докладе мы поговорим о настройке проекта, возможностях
      библиотеки и разберём реальный use-case добавления global naming
      strategy в kotlinx.serialization.

      <p>Данный доклад будет интересен продвинутой аудитории,

      <p>"I've been working on updating the "On Java 8" book for the Chinese
      translation, which includes subsections on new Java features through
      JDK 17. In the process, I created an example that summarizes a lot of
      these features, including records, sealed classes and (Preview)
      pattern matching.<p>

      <p>I have created a complementary example in Kotlin. My plan is to
      talk through the Java & Kotlin features, and discuss how the Java
      features are definite improvements to that language, but still fall
      rather dramatically short of what Kotlin provides (the Java approach
      also contains what I consider to be fundamental design flaws).<p>

      behalf.It must translate Kotlin specific constructs into concepts the
      VM can understand, which requires that it reinterpret your code in
      unexpected ways.This applies to both simple things like symbol names
      and complex abstractions like suspending and composable functions.<p>

      <p>Kotlin/Multiplatform is a complicated piece of tech! Because it
      chose to integrate inside native development tools & workflows,
      setting up a clean and shareable project can be complicated. Here’s
      everything you need to set up a production ready architecture.<p>

      <p>In this talk, we will explain how to architecture your code for a
      multi-platform mobile application, how to efficiently share business &
      behaviour code between your native apps, and how to configure each
      project (Common, Android & iOS) to link them to the business library.
      We’ll discuss various patterns that we can use to standardise
      communication between the frontend (the UI) and the backend (the
      business logic) to ensure that the behaviour of our application
      remains strictly equivalent no matter the actual platform. We’ll also
      show how to automatically test your common code, and how to deploy the
      various produced artifacts when working with application specific
      teams.<p>

      <p>In this talk, we’ll dive into more "advanced" Jetpack Compose
      features that rely on architecture, generics and meaningful motion.
      These are all topics that go beyond the basics of creating Compose UI,
      that are crucial in every app!<p>

      <p>W’ll explore state handling and reactive and uniform data flow
      structures - how to connect Compose components to observable
      structures such as LiveData, coroutine Flows, Rx and finally State
      structures from the Compose framework. You’ll learn how to show
      different types of UI based on state and how Compose reacts to state
      changes to re-draw the UI.<p>

      <p>Next, you’ll learn about beautiful and easy to implement animations
      and how to use the Transition API to animate multiple states at the
      same time. Finally, once you create the animations, you’ll learn how
      to apply the state from them to your UI for smooth screen
      transitions.<p>

      <p>And last, but not least, we’ll talk about code reusability through
      generics and generic Composable functions. With the power of Kotlin
      and its strong type system, in pair with Compose being fully written
      in Kotlin and relying on functions, you can create truly reusable
      generic components, without much code.<p>

      <p>Join me in this talk and you’ll get a better sense of how awesome
      Compose can be!<p>

      - Why you should consider this library for image loading

      - Understanding its API

      - How it works. By covering its entire image loading pipeline.

      By the end, you'll walk away with the advantages of using COIL and its
      image loading pipeline.<p>

      <p>These last years had been really exciting for app development.
      First, Android developers moved to Kotlin, then we had Kotlin
      Multiplatform where we managed to have our app’s business logic shared
      across iOS and desktop.<p>

      <p>Now with Compose we can go even further and reuse the UI. In this
      talk, I’m going to show you can create a library and the UI for your
      Android application and share it across a Desktop app and the web - it
      just works*.<p>

      <p>In this talk we'll see how, using a large deal of the Kotlin

      applications, which are testable, scalable and clean.<p>

      <p>We'll touch upon the topic of dispatching, thread switching and
      synchronisation mechanisms, building operators using coroutines, and
      creating our own API which abstracts away the threading, contexts and
      dispatching logic of coroutines.<p>

  description:
    __cdata: >

      <p>In some particular cases, providing a DSL can greatly improve the
      productivity of your dev team. Java is not the best language to
      provide such DSL. But Kotlin has tons of features that can help you
      there.<p>

      <p>Kotlin is one of those “new” JVM languages that are currently
      rocking the boat. Although it’s made a great impact on Android, it’s
      equally good on the server side. As Domain-Specific Languages are
      constrained by the language they run on, Kotlin frees developers from
      Java fluent builders to propose something better.<p>

      <p>Using the Vaadin web framework as an example, I’ll demo how one
      could design its own DSL with Kotlin.<p>

      <p>Kotlin is becoming a mature and established back-end language. The
      maturity of a language is not only measured by its features but also
      by its community and ecosystem. Kotlin's ecosystem for server-side
      development is growing very fast. Coming from the Java development
      side, Spring would be a default fallback option to build your
      application. While Spring is also hopping on the Kotlin train, the
      rest of Kotlin's ecosystem is growing fast. More and more new
      frameworks are popping up implementing different points of view on how
      to build your service. Those new frameworks might change our ways of
      developing back-end applications. Let’s have a look out there!<p>

      <p>Coroutines are a cool mechanism for orchestrating asynchronous work

      <p>Other languages like python, C#, and C++ have supported these
      techniques for quite a while, but Kotlin was the first language able
      to run coroutines on JVM. Coroutines have become a strong competitor
      to Futures, CompletableFutures, and Reactive Programming paradigm
      (rxjava and reactor), winning great victories on the Android
      battlefield. Furthermore, some teams are now considering the use of
      coroutines also on backend systems to optimize thread usage for
      high-TPS systems.<p>

      <p>This event will demonstrate the core features of coroutines,
      implemented with Kotlin. Yes, there will be Kotlin code.<p>

      <p>Zusammenfassung: Kotlin ist gereift. Es stehen Effizienzgewinne
      beim Schreiben (und Lesen) von Quellcodes zur Diskussion, die gerade
      bei komplexen Business-Anwendungen von Nutzen sein können.
      IT-Architekten stehen jetzt vor der Frage: „Lohnt sich das? Wie
      kompliziert ist eine Umstellung mit all unseren Bibliotheken, was kann
      koexistieren und was wird vorausgesetzt?“<p>

      <p>Der Vortrag beginnt mit einem kurzen Überblick für die Gründe der
      Einführung. Danach werden wir eine Beispielanwendung von Java nach
      Kotlin migrieren, welche unsere Erkenntnisse aus dem Kundenprojekt
      veranschaulicht. Die Anwendung im Status vor der Umstellung kann auf
      Github angeschaut werden:
      https://github.com/viadee/kotlin_camunda_webcast_2021<p>

      <p>Die ursprüngliche Java-Anwendung basiert auf Camunda mit Spring
      Boot. Für Daten-Mappings setzten wir auf MapStruct. Die
      Intergrationstests nutzen Junit5, Mockito und bmp-assert/assertJ. Das
      Buildtool ist Maven. Das gezeigte Szenario ist mehr als nur ein
      Beispiel, vielmehr ist es eine Zusammenstellung von Bibliotheken und
      Werkzeugen, die wir bei vielen unserer Kunden vorfinden und mit denen
      wir echte Anwendungen nach Kotlin migriert und erfolgreich in die
      Produktion gebracht haben. Die Anwendung werden wir im ersten Schritt
      für die Entwicklung mit Kotlin erweitern und dann die einzelnen
      Java-Bestandteile nach Kotlin migrieren, bis die gesamte Anwendung auf
      Kotlin umgestellt ist.<p>

      <p>In this session, we will explore a fast, intuitive way to build
      great mobile applications using Realm’s new Kotlin SDK with
      Multiplatform support.<p>

      <p>We will dive deeper into how we evolved the Realm Java SDK to be a
      fully native Kotlin Multiplatform SDK. You will learn how Realm’s
      natural object model combined with Kotlin features like Coroutines and
      Flows reduces boilerplate, promotes testability, and allows for
      maximum code sharing between Multiplatform projects.<p>

      <p>And you will see just how little code is needed to sync data in
      real-time between Android, iOS and Desktop clients, all in a single
      codebase.<p>

  description:
    __cdata: >

      <p>Code efficiency today is often treated indulgently. To a certain
      degree, it is reasonable. Memory is cheap and developers are
      expensive. Though at some point maybe your application runs on
      millions of devices and some battery use optimization might save
      enough energy to power a small city. Or maybe your company already
      pays lots of money for servers and their maintenance, and some
      optimization might make it significantly cheaper. Or even your
      application works well for a small number of requests but does not
      scale well and on the day of the trial it shuts down. In this session,
      I'll show you how to make an efficient Kotlin code cheaply, and how to
      optimize performance-critical parts of your code.<p>

    Kotlin Multiplatform Mobile in production: key takeaways from developing

  description:
    __cdata: >

      <p>Kotlin Multiplatform Mobile is a young promising technology, but is
      it there to stay? And is it worth trying out? This talk is based on
      the experience of developing two very different cross-platform apps
      with KMM. The goal of this talk is to introduce KMM, discuss the
      pitfalls that a new KMM developer may encounter and share some
      valuable tips that were collected along the way of KMM development:
      from preferable app architecture to team requirements.<p>

      <p>Unit tests are boring and maintaining them is complex? Sometimes.
      But it doesn't have to be this way.<p>

      <p>To create great readable tests with ease we have to go further than
      standard Java tooling. To achieve that we can incorporate idiomatic
      Kotlin into test code. It will help us design tests to be both
      developer and machine friendly.<p>

      <p>During the talk we will refactor step-by-step Java with JUnit test
      to Kotlin with Kotest. We will look at differences between various
      tools and we will check how test tech stack choices are influencing
      developer productivity.<p>

      <p>I will show practical application of Kotlin idioms in test,
      including, but not limited to, assertions, mocking and test suite
      definition.<p>

  subject: The Kotlin/Swift boundary
  url: https://www.berlin.droidcon.com/schedule
  description:
    __cdata: >

      <p>Kotlin/Native can compile to Objective-C-compatible bytecode, but
      that doesn’t mean it looks natural to native iOS developers. While
      Kotlin and Swift are syntactically very similar, they solve certain
      problems in very different ways. For example, a Swift developer often
      uses a struct where a Kotlin developer uses a data class. This means
      the default ways that things translate from Kotlin through Objective-C
      into Swift don’t always come out looking idiomatic.<p>

      <p>We’ll talk through some of these differences, and strategies for
      dealing with them. Kotlin, Objective-C, and Swift are three different
      languages, and so we shouldn’t expect to be able to translate between
      them perfectly. But with a bit of care at the interop layer, we can
      make things a lot smoother in the iOS code.<p>

  subject: Coroutines for Kotlin Multiplatform in practise
  url: https://www.berlin.droidcon.com/schedule
  description:
    __cdata: >

      <p>With coroutines being the de facto way of exposing async work and
      streams of changes for Kotlin on Android, developers are obviously
      attempting to use the same approaches when moving their code to
      Multiplatform.<p>

      <p>But due to the way the memory model differs between JVM and Kotlin
      Native, it can be a painful experience.<p>

      <p>In this talk, we will take a deep dive into the Coroutine API for
      Kotlin Multiplatform. You will learn how to expose your API with
      Coroutines while working with the Kotlin Native memory model instead
      of against it, and avoid the dragons along the way.<p>

  subject: Using Kotlin Flow in MVVM
  url: https://www.berlin.droidcon.com/schedule
  description:
    __cdata: >

      <p>LiveData was never designed to be a full-fledged reactive stream.
      Thread management with LiveData is very hard and making data
      transformation with transformation operators is very limited.
      Moreover, testing LiveData becomes very tricky and is likely to open
      for race conditions if you are using it with coroutines.<p>

      <p>Luckily, Kotlin Flow provides asynchronously computed values with
      the power of Coroutines. Making data transformations becomes very easy
      with Flow intermediate operators. Furthermore, StateFlow provides
      caching the current state just like LiveData. Since there is a
      back-pressure in Flow, unit testing is much simpler with handy Flow
      terminal operators.<p>

      <p>Kotlin Flow is a very powerful reactive stream with its robust
      operators. Using Flow instead of LiveData makes it easier to handle
      data transformations and background processes. Finally, testing Flow
      is much safer and painless compared to LiveData.<p>

      code walkthrough and demo of sample apps that involve network and
      database) and how can we unit test Kotlin flow.

      In this session, we will have a live workshop, where the attendees
      will learn using Flow with MVVM Architecture & learn unit testing
      Kotlin flow code with runBlockingTest and TestCoroutineDispatcher &
      Turbine library.<p>

      <p>In this talk, the dynamic duo will go out of their comfort zone and
      recreate a Breakout clone for the browser using KotlinJS.<p>

      <p>At Instil Software they standardize on Kotlin for server-side
      development. Within the training team, they offer a Kotlin native
      workshop, for which Garth and Eamonn wrote a Kotlin native version of
      the classic game Breakout.<p>

      <p>Being massive TypeScript fans, it would always be their language of
      choice when working on JavaScript platforms. They didn't feel the
      drive to switch to other languages that transpile to JS such as Fable
      (F#), Scala.js, or even KotlinJS, as they always saw Kotlin on the JVM
      as the solution to a problem, the problem being Java.<p>

      <p>They will make use of React, Redux and use React Three Fiber for
      WebGL graphics. Moreover, they will explore what this transition to
      KotlinJS is like for a TypeScript fanboy and try to answer some
      questions along the way.<p>

      <p>You'll learn how the tooling, libraries and language features
      compare, what things tripped up and whether you should switch and use
      it on your next project<p>

      <p>In this workshop we will learn the full Kotlin/JS feature set by

      from scratch based on the Kotlin Gradle DSL, and then iteratively
      assemble a rich UI via the Kotlin/JS language and Kotlin-React DSL.
      Application state will be managed via Redux using the functional style
      with React Hooks.<p>

      <p>You'll learn how coroutines simplify asynchronous workflows and
      concurrency. You'll also learn how interoperability with TypeScript
      allows you to leverage existing JS libraries in a strongly typed
      way.<p>

      <p>By the end of the workshop you will have been exposed to some of
      the advanced features of Kotlin and be comfortable using Kotlin for JS
      platforms.<p>

      <p>If we look at Finite State Machines (FSM), we can find a number of
      examples everywhere in the world that surrounds us. There are vending
      machines, subway entrance turnstiles, heating systems, self-driving
      cars, elevators, etc., but also many, many cases of UI frameworks like
      Android's UI lifecycle (arguably a finite state machine). The concept
      of FSM and its mathematical computational model are very interesting
      to implement in many programming languages. With Kotlin's recent
      investment in asynchronous programming tools, it seemed like a good
      time to look into it.</p>

      <p>This talk provides a brief introduction about Kotlin Co-routines
      and explains the scenarios when one should try using the same and when
      to avoid it using practical examples. The session will also help
      developers understand how Co-routines work and the best practices for
      using the same.</p>

      <p>As software developers, we often tend to use what is considered
      best practice without understanding the practical applicability of the
      same in our own applications.</p>

      <p>Through this talk, my aim is to help developers understand areas /
      use cases where Co-routines can prove much effective as well as less
      effective. It will not focus on downsides of Co-routines but mainly on
      the applicability of it in different scenarios based on my experience

      side, Spring would be a default fallback option to build your
      application. While Spring is also hopping on the Kotlin train, the

      to build your service. Those new frameworks might change our ways of

      <p>Kotlin is a JVM-based language, and many of its features are

      to work well with Java and to be easy for existing Java developers to

      that surprise Java developers. This talk will review several of those
      features, and help existing Java developers understand them and use
      them productively.</p>

      <p>Examples will include how to create static properties and methods

      <p>Learn the basic syntax and semantics for the Kotlin programming
      language. Kotlin is an alternative JVM language that provides null
      safety, static typing, and powerful IDE support. This workshop will
      give you the chance to code in Kotlin, highlighting its similarities
      and differences from Java, how to use functional programming skills,
      work with collections, access restful web services, and more.</p>

      <p>This workshop will examine features of Kotlin at a greater depth
      than most tutorials. Coroutines – the most popular feature of the
      language – will also be covered, as well as higher order functions,
      reduction operations like reduce and fold, and lambdas with receivers.
      Those topics progress toward building DSLs and builders in Kotlin.
      Terms like “apply”, “let”, “use”, “also”, and “with” will be covered
      along with their typical use cases.</p>

      <p>Details of the type system, including the Any, Unit, and Nothing
      classes, will be included. Examples will be provided on how to define
      extension functions, infix operators, and inlining functions for
      efficiency.</p>

      <p>Most developers are aware that Kotlin is the language of choice for
      Android applications, it can also be used effectively on the server
      side. The Spring Framework in particular makes excellent use of Kotlin
      features. Spring supports Kotlin data classes and reified types,
      provides extension functions and small domain-specific languages for
      bean configuration and testing, and more.</p>

      <p>MThis talk will show how Kotlin fits into the Spring ecosystem and
      how Spring developers can benefit from its null safety, strong typing,
      and powerful support for concurrency.</p>

      application we will learn how to break the application into separate
      services that communicate via gRPC Kotlin. We will then learn how to
      containerize and deploy the application to Kubernetes. Along the way
      we will learn how to address some of the major challenges of deploying
      applications to Kubernetes, such as scaling and service discovery.</p>

      <p>Some of the topics to be covered include:</p>

  description:

      <p>Mockito has been used in testing kotlin/android apps since long,
      however there is setup required and a lot of boilerplate code required
      to test certain kotlin components as well as a need to use other
      libraries like PowerMock for the features that Mockito doesn’t
      support. Mockk, a mocking framework with first-class support for
      kotlin features, comes to the rescue and helps developers write unit
      tests easily as well as improve code coverage without having to do
      extra setup/ write boilerplate code or use other mocking
      frameworks.</p>

      <p>In this session, we will look at codebase of an android app and
      learn the following,

      1- how mockk can help us test the various application
      components(objects, classes, enums, constructors, chaining calls,
      hierarchial mocking, verification order, extension functions,
      coroutines, deferred and suspending functions, private and static
      functions, capturing and replaying arguments, relaxed mocking,
      top-level functions)

      2- how mockk is better than mockito in testing 1

      3- which is better for code coverage – mockk vs mockito</p>

      <p>Kotlin Coroutines is a powerful threading library for Kotlin,
      released by JetBrains in 2018. At The New York Times, we recently
      migrated our core libraries and parts of our News app from RxJava to
      Kotlin Coroutines. In this talk we’ll share lessons learned and best
      practices to understand, migrate to, and use Kotlin Coroutines &
      Flows.</p>

      <p>In this presentation, you will learn:</p>

      <p>What Coroutines are and how they function

      How to use Kotlin Coroutines & Flows (with real world examples and
      demos)

      Where and why you should use Coroutines & Flows in your app

      How to avoid the pitfalls of Coroutines

      Kotlin Coroutines vs. RxJava

      Lessons learned from migrating to Kotlin Coroutines from RxJava in
      large legacy projects & libraries

      By the end of this talk, you will be able to apply Kotlin Coroutines
      to your own app, run the provided sample code yourself, and convince
      your team to give Kotlin Coroutines a try!</p>

      <p>Ok, Kotlin is cool and fun. It's even better with built in

      development, I would like to share my recent experience of using
      coroutines.</p>

      <p>I will start with briefly looking at different concurrency
      models/patterns such as traditional thread based, asynchronous
      callback-based, futures, actor-based and coroutine based concurrency.
      Then I'll dive a little deeper into Kotlin coroutines, how they work
      and their pros and cons.</p>

      <p>Finally, I would like to show how I used coroutines in a backend
      service that I recently worked on. The aim is to show the application
      of coroutines in a real-world use case.</p>

  description:
    __cdata: >

      <p>Within a few weeks after pitching Kotlin, our team migrated a
      12,000 line codebase from Java to Kotlin alongside planned Sprint
      work. This sparked interest among management and colleague developers,
      which eventually led to the creation of the Kotlin Movement at the
      Rabobank. And what an incredible journey it has been!</p>

      <p>Within just a few months, we set up a Kotlin Community, organized
      study groups, developed an adoption & migration guide, presented at
      our in-house IT conference, and were able to advise different teams
      about migrating to Kotlin.</p>

      <p>In this talk, I’ll explain why Kotlin has been my favorite language
      for over four years and how it led to a movement within the Rabobank.
      I’ll discuss what the benefits of Kotlin over Java are and why the
      trade-offs for migrating often make sense. I’ll demonstrate how easy
      it is to convert a database-backed Java-based Spring Boot application
      to Kotlin using the built-in converter and just a tiny bit of coding.
      And finally, I’ll share how we convinced managers and developers to
      get on board – and how YOU can do that, too!</p>

    Getting ready for Declarative UIs with Unidirectional Data Flow using
    Kotlin Coroutines
  url: https://www.meetup.com/kotlin-london/events/278197968
  description:
    __cdata: >

      <p>Unidirectional Data Flow (UDF) is a powerful technique that
      enhances our Reactive apps to work deterministically. Synchronising
      our views with fresh data was never an easy task to accomplish. For
      this same reason, there are mechanisms that support us to make that
      possible. Surely callbacks were a thing in the past, however, they
      were an antipattern themselves due to the lack of readability. Now we
      don’t need to deal with them anymore thanks to Kotlin Coroutines.
      Getting ready for Declarative UIs with Kotlin Coroutines and friends
      is indeed feasible, now we could use suspend functions, Flow and in
      the end, StateFlow would make our Reactive apps ready for Declarative
      UIs. Let’s define a single entry point, receive data, transform it
      into a state, and render each state. Let’s get our apps ready for a
      Declarative UI world on Android.</p>

      <p>You’ll learn how to use Kotlin Coroutines and friends from the
      Kotlin Coroutines library to take advantage of really efficient and
      easy to read code. How to handle its lifecycle without being
      compromised to a specific external Android framework, which would
      enable your code to be prepared for more purposes than Android-only
      apps.</p>

      <p>Занимаясь прототипированием, data scientist хочет, чтобы ничто не

      зависимости подключались по возможности просто, а тулинг помогал лучше
      ориентироваться в исследуемых данных.

      библиотек делать их удобными для использования в ноутбуках. Рассмотрим
      отображение объектов, pre-evaluation и post-evaluation коллбэки, а

      quickly moving to production. The framework is as clean as it gets,
      wouldn't it be nice if the language matched its elegance?</p>

      <p>Google's gRPC is a valuable tool in defining back-end services that

      one may prefer to use it with respect to its alternatives(e.g. REST
      and/or OpenAPI), and then dive into its use in combination with
      Kotlin. The gRPC team now provides full support for generating sever
      and client code using suspended methods and Kotlin Flows, giving
      coroutines first class treatment and allowing engineers to provide
      powerful asynchronous expressively implemented services.</p>

      yourself? How about building a beautiful and feature rich CLI in a JVM
      language? Sounds impractical, since JVM languages need a virtual
      machine to run on.</p>

      <p>Well, not anymore! With Clikt and GraalVM, it is possible to create
      these CLIs with ease, and even create native platform binaries for
      every major platform architecture.

      In this talk, I'll show you how we created a CLI with these
      technologies, and even automated the process of compiling them to
      binaries for various platforms (Windows, OSX & Linux). After this
      talk, you'll be ready to start building you own platform native
      CLI's!</p>

      <p>Kotlin has been the new superhero on the JVM team for the last
      couple of years now. With significant support from both JetBrains and
      the community Kotlin has managed to find a good balance between new
      features and understandability.</p>

      <p>However, with great power comes great responsibility. Every new
      feature holds new ways to shoot yourself in the foot. Every bit of
      syntactic sugar has the potential to introduce an incomprehensible
      layer of abstraction.</p>

      <p>Amongst all the awesome features of Kotlin, which ones have the
      potential to harm more than they help? Which ones should you handle
      with care? How do you make sure that your Kotlin code is not only
      shiny and new, but also genuinely better?</p>

      <p>Kotlin is becoming a mature and established back-end language. The
      maturity of a language is not only measured by its features but also
      by its community and ecosystem. Kotlin's ecosystem for server-side
      development is growing very fast. Coming from the Java development
      side, Spring would be a default fallback option to build your
      application. While Spring is also hopping on the Kotlin train, the
      rest of Kotlin's ecosystem is growing fast. More and more new
      frameworks are popping up implementing different point of views on how
      to build your service. Those new frameworks might change our ways of
      developing back-end applications. Let’s have a look out there!</p>

      <p>Mobile, Web, Desktop... when working with multiple platforms for
      your product, you might start to feel like there is a lot for your
      team to maintain. If we update the design for a feature or want to
      test a new layout, we often need to make that change in multiple
      clients. This results in more time spent on the same task in multiple
      places, with less time being able to focus on delivering even more
      value to your users./p>

      <p>With the use of declarative UI frameworks on the rise, there are
      more opportunities opening up that allow us to experiment with how we
      build our applications. Whilst Server Driven UI is nothing new, pair
      this with strongly typed server-side technologies and dynamically
      building our user interfaces becomes both simpler and safer./p>

      <p>In this talk we'll explore how we can utilise GraphQL to declare
      the presentation of our apps, with this being used to build our
      Jetpack Compose, SwiftUI or React components to be displayed on
      screen. With this knowledge we'll be able to start thinking about how
      we can build more dynamic UIs whilst utilising modern approaches when
      doing so.</p>

      <p>In unserem Meetup möchten wir Euch das Erstellen zweier
      Microservices mit dem Anwendungsframework Ktor im praktischen Einsatz
      vorstellen. Miteinander kommunizieren sollen die beiden Microservices
      über einen zentralen Event Bus. Hierfür setzen wir das Event Messaging
      System NATS ein. Wir schaffen damit ein flexibles und
      leichtgewichtiges Setup, welches die Arbeitsweise von Microservices in
      einem Live-System nachstellt.</p>

      <p>Das Framework Ktor kommt aus dem Hause JetBrains und ist in der
      hauseigenen Programmiersprache Kotlin verfasst. Es ermöglicht eine
      schnelle Realisierung von Web-Client- und Server-Applikationen und
      bietet sich daher gut zur Erstellung von Microservices in vernetzten
      Systemen an. Als Package Manager und Build Tool wird Gradle
      verwendet.</p>

      <p>Wir erstellen mit Ktor zwei einfache Webservices und demonstrieren
      ein paar der wichtigsten Features dieses Frameworks. Hierzu gehören
      Auto Reload, Routing, Basic User Authentification und Json.</p>

      <p>Beleuchtet werden darüberhinaus die Vorteile gegenüber etablierter
      Lösungen wie beispielsweise Spring Boot oder Symfony.</p>

      <p>At a point in the past, it was forecast that Java would die, but
      the JVM platform would be its legacy. And in fact, for a long time,
      the JVM has been tremendously successful. Wikipedia itself lists a
      bunch of languages that run on it, some of them close to Java e.g.
      Kotlin, some of them very remote e.g. Clojure.</p>

      <p>But nowadays, the Cloud is becoming ubiquitous. Containerization is
      the way to go to alleviate some of the vendor lock-in issues.
      Kubernetes is a de facto platform. If a container needs to be killed
      for whatever reason (resource consumption, unhealthy, etc.), a new one
      needs to replace it as fast as possible. In that context, the JVM
      seems to be a dead-end: its startup time is huge in comparison to a
      native process. Likewise, it consumes a lot of memory that just
      increase the monthly bill.</p>

      <p>What does that mean for us developers? Has all the time spent in
      learning the JVM ecosystem been invested with no hope of return over
      investment? Shall we need to invest even more time in new languages,
      frameworks, libraries, etc.? That is one possibility for sure. But we
      can also leverage our existing knowledge, and embrace the Cloud and
      containers ways with the help of some tools.</p>

      <p>In this talk, I’ll create a simple URL shortener with a “standard”
      stack: Kotlin, JAX-RS and Hazelcast. Then, with the help of Quarkus
      and GraalVM, I’ll turn this application into a native executable with
      all Cloud/Container related work has been moved to the build
      process.</p>

      <p>Programmers tend to use strongly typed languages for the safety in
      the runtime and their own comfort while developing applications. While
      using new dependency, they often have to browse the documentation by
      symbolic names of classes and functions. Oftentimes, they don’t know
      the function name, but are convinced there must be a function
      somewhere that fits given type transformation.</p>

      p>In this talk, we will focus on a prototype tool that lets you browse

      <p>Unidirectional Data Flow (UDF) is a powerful technique that
      enhances our Reactive apps to work deterministically. Synchronising
      our views with fresh data was never an easy task to accomplish. For
      this same reason, there are mechanisms that support us to make that
      possible. Surely callbacks were a thing in the past, however, they
      were an antipattern themselves due to the lack of readability. Now we
      don't need to deal with them any more thanks to Kotlin Coroutines.
      Getting ready for Declarative UIs with Kotlin Coroutines and friends
      is indeed feasible, now we could use suspend functions, Flow and in
      the end StateFlow would make our Reactive apps ready for Declarative
      UIs. Let’s define a single entry point, receive data, transform it
      into a state, and render each state. Let’s get our apps ready for a
      Declarative UI world on Android.</p>

      <p>You'll learn how to use Kotlin Coroutines and friends from the
      Kotlin Coroutines library to take advantage of really efficient and
      easy to read code. How to handle its lifecycle without being
      compromised to a specific external Android framework, which would
      enable your code to be prepared for more purposes than Android only
      apps.</p>

      hopefully helps you with finding a good fit for your next project</p>

      <p>Let's have a look at a real life borrowed REST endpoint, written in
      Kotlin (dahhh) using Spring, Ktor, Micronaut and Jooby. We'll compare
      the efforts, timings and developer experience and collect pros and

      <p>In this talk, I’ll demo how you can migrate a traditional sample
      Spring Boot application written in Kotlin to coroutines one step at a
      time via a hands-on demo.</p>

      <p>From Wikipedia, Reactive Programming is 'a declarative programming
      paradigm concerned with data streams and the propagation of
      change.</p>

      <p>The programming model is complex to master. It requires a lot of
      experience to feel comfortable with it. However, there’s no denying
      that it fits the cloud ecosystem perfectly. Since on-premises
      infrastructure is oversized, running a program that executes a couple
      of additional CPU cycles won’t change anything. On the other hand, you
      will pay for them if you host the same program on third-party
      infrastructure. Depending on the number of those cycles, and the
      number of nodes the program runs on, it can make a huge difference in
      your monthly bill.</p>

  description:
    __cdata: >

      <p>Developing for multiplatform is picking up speed as the Kotlin
      Multiplatform gets better with every release. That mostly means that
      shared logic is being written in Kotlin which can then be targeted to
      many target platforms. Up until recently it wasn't easy to develop UI
      for multiple platforms on the Desktop side. That is changing with the
      introduction of Compose for Desktop, which will allow building
      application UI for Linux, macOS and Windows.</p>

      <p>In this session you will get to understand what is Compose for
      Desktop, how does it work and how can you jump right into building for
      multiple platforms opening up the vast domains other than the
      mobile.</p>

  description:
    __cdata: >

      <p>Dependency management in the Kotlin and in the JVM ecosystems is
      great, especially for Gradle users, but there's room for
      improvement.</p>

      <p>Some tasks, like upgrading dependencies to the right versions, are
      still tedious and time consuming. There's also compatibility gotchas
      because of the lack of metadata.</p>

      <p>This talk will start with a mention of the different problems that
      come with dependency management in real-world projects. Then it'll
      show how the developer tool refreshVersions (MIT licensed) tackles
      some of these issues in Gradle projects, saving a lot of time when
      upgrading dependencies.</p>

      <p>Finally, I'll talk about what the future can be for dependency
      management, be it from new features in future Gradle versions, or
      tools or conventions that the community can create to improve the
      status quo.</p>

      introduced by the upcoming Project Valhalla and JVM support for sealed
      classes and records. In this talk, we’ll discuss how these changes
      affect Kotlin as a language, and how the Kotlin team finds a balance
      between drawing on the power of the new JVM versions, supporting the
      same functionality in older versions, and providing a smooth
      transition. We'll also talk about how you, the community, can
      influence the design and evolution of the language!</p>

      <p>Kotlin (/ˈkɒtlɪn/)[2] is a cross-platform, statically typed,
      general-purpose programming language with type inference. Kotlin is
      designed to interoperate fully with Java, and the JVM version of its
      standard library depends on the Java Class Library,[3] but type
      inference allows its syntax to be more concise. Kotlin mainly targets
      the JVM, but also compiles to JavaScript or native code (via LLVM).
      Language development costs are borne by JetBrains, while the Kotlin
      Foundation protects the Kotlin trademark.</p>

      other programming languages, such as Rust, Go, and Kotlin, and
      software-related monetary technologies based upon Bitcoin.</p

      <p>For our meetings, we read a chapter from a book we've selected and
      then present the sections of that chapter to each other, each
      participant taking responsibility for a section or two. We pause after
      each section to allow for discussion and questions. At the end of each
      meeting we decide when we're meeting next. The more you present, the
      more you learn.</p>

      <p>When JSR 371 was dropped from the scope of Java EE, Oracle made the
      decision to allow the Community to finalize the specification. It
      quickly became known as the "Community JSR" and the slogan
      "@Controller to the Community" grew out of it.</p>

      <p>All the Java EE 8 specifications were transferred to Eclipse
      Foundation and Jakarta EE, MVC was once again left behind. We managed
      to release MVC 1.0 through the JCP and has since moved over to Jakarta
      EE as well and released Jakarta MVC 1.1 through the Jakarta EE
      Specification Process. And we don't stop there, these days, Jakarta
      MVC 2.0 is on its way out. Maybe it is time for a new slogan? "The
      Specification that Never Dies!"?</p>

      <p>In this talk, I will take you through this journey and show all
      aspects of Jakarta MVC 2.0 in code. You don't want to miss this!</p>

  description:
    __cdata: >

      <p>Very many good books on OO design have advised us to choose
      delegation over inheritance. Yet, most developers using OO languages
      like Java use inheritance predominantly compared to delegation. Part
      of the reason is the lack of support for delegation when compared to
      inheritance. In this presentation we will see how Kotlin has first
      class support for delegation. We will look at how delegation helps us
      better model relationships and take a look at some usecases of
      applying delegates in Kotlin.</p>

  description:
    __cdata: >

      <p>This time the topic will revolve around our favourite Kotlin, or
      more specifically: Going Reactive with Spring & Kotlin

      There's been a lot of buzz around reactive programming in recent
      years. Spring, being the dominating framework in the JVM world, didn't
      disappoint and introduced its reactive-stack web framework WebFlux in
      Spring 5. Together with this, they also saw the rise of Kotlin coming
      and they introduced dedicated Kotlin support for the Spring 5 with the
      goal to make Kotlin a first-class citizen of the ecosystem. In this
      talk we'll have a look at some of the results this collaboration has
      led. We'll have a look at a good old blocking Spring MVC service and
      transform it into a fully reactive one using WebFlux, Kotlin and
      coroutines.</p>

      <p>When designing a library, minimizing your API surface - the types,
      methods, properties, and functions you expose to the outside world -
      is a great idea. This doesn't apply to just libraries: it's a
      consideration you should make for every module in a multi-module
      project. In this talk, we'll look at all the ways that Kotlin lets you
      get your visibility just right.</p>

      <p>Quarkus is a Kubernetes Native Java stack tailored for OpenJDK
      HotSpot and GraalVM.

      It flips your assumption about how fast and small a JVM-based
      application can be.

      Quarkus enables applications to boot super fast and occupy tiny memory
      and disk spaces compared to the equivalent applications developed with
      traditional Java/JavaEE frameworks. In addition to that, Quarkus
      provides a range of tools and features that make writing, testing,
      building and deploying applications easy and fun.</p>

      <p>During this session we will use Kotlin to write a microservice with
      Quarkus to demonstrate its cloud-native power.</p>

      <p>The coroutines library contains many features for starting
      coroutines, creating Flows and Channels, and handling a mutable shared
      state. But, how do we use them, how do they work and what are good use
      cases?  In this talk, we will explore basic to advanced features
      provided by the coroutines library. We'll look at when to use state
      flow, shared flow, and every type of Channel. We'll explore
      lesser-known features and their use cases such as selectors and
      actors. Did you know combining Flows uses selectors under the hood?
      What are they? Mohit will share his learnings from his extensive
      experience in using these constructs!</p>

      <p>We’ve been using JDBC to access our SQL databases for decades, but
      JDBC is a blocking API. Blocking API’s can be problematic at times,
      and after years of promises, a ‘non blocking JDBC’ is on the horizon.
      When your application queries a database using JDBC, the thread used
      to make that query blocks: It simply waits while your database
      processes this request. It’s simple. It’s easy to reason about, but
      ultimately it can be a big waste of threads, and with that memory and
      CPU. For NoSQL databases like MongoDB and Cassandra non-blocking
      drivers are well established, but for SQL databases we’re generally
      stuck with JDBC i.e. blocking threads. There has been talk about some
      kind of ‘non-blocking’ JDBC for years, and finally it is
      happening.</p>

      <p>Many Android developers are working in Kotlin nowadays. On Android,
      your Kotlin source code gets compiled to Java bytecode, and eventually
      to Dalvik bytecode. How is the result different compared to starting
      from Java source code then? Is it compatible? Can it be as compact? Is
      it as secure?</p>

      <p>We'll look at the differences. We've extended our open source code
      optimizer ProGuard and our protection software DexGuard to fully
      support Kotlin. We'll now share our experiences and point out what can
      be important in your apps and in your libraries. We'll demonstrate a
      new open source tool to view the

      Kotlin metadata hiding inside your apps. We'll show how to optimize
      and obfuscate Kotlin libraries in such a way that they remain
      compatible in other Kotlin projects.</p>

      <p>Armed with this knowledge, you'll better understand your own Kotlin
      projects and you can tune them to create more compact and more secure
      software.</p>

    Why Exception Handling with Kotlin Coroutines is hard and how to master
    it
  url: https://www.online.droidcon.com/agenda-dcamericas
  description:
    __cdata: >

      <p>Getting the “happy path” right with Kotlin Coroutines is pretty
      straightforward. On the other hand, handling exceptions appropriately
      when something goes wrong is not that trivial.</p>

      <p>In this talk, you will learn about the reasons for the complexity
      of exception handling with Kotlin Coroutines and about all things you
      need to consider to appropriately deal with occurring exceptions.

      You will learn when you should use a conventional try-catch clause,
      and when you should install a CoroutineExceptionHandler instead.

      You will also learn about the special properties of top-level
      Coroutines when it comes to exception handling and how they differ
      when they are starting with launch and async.

      Furthermore, you will learn all about the exception handling
      peculiarities of the scoping functions coroutineScope{} and
      supervisorScope{} and why you should re-throw CancellationExceptions
      to avoid subtle errors.</p>

      <p>This talk is for developers that are already familiar with the
      basics of Kotlin Coroutines but still struggle to understand how
      exception handling works in detail. By the end of this talk, you will
      have a better understanding of how exceptions are treated by the
      Coroutines machinery and how you can handle them appropriately.</p>

      <p>Kotlin hilft uns, mit unseren bekannten Tools Software besser zu

      vielen Stellen versucht es Designfehler von Java auszumerzen und
      bringt neue Programmiermodelle mit, die uns unterstützen Probleme mit
      neuem Handwerkszeug zu meistern. Dabei ist Kotlin dafür ausgelegt,
      sich nahtlos in bestehende Java-Projekte zu integrieren und selbst auf
      älteren 1.6 JVMs zu laufen. Ob Delegations, Reified Types… wir werden
      uns anschauen, welche Kotlin Features ein Java Entwickler kennen
      sollte und wie sie uns weiterhelfen. Dabei nehmen wir auch das
      aktuelle Kotlin Update mit Coroutinen und Inline Classes unter die
      Lupe. Der Vortrag richtet sich sowohl an Kotlin-Neueinsteiger, als
      auch an Fortgeschrittene, die sich für die Neuerungen der Updates

      <p>Programming might not be magic, but it can definitely feel magical.
      But the more magic you need to scrape away, the harder it gets. Let’s
      face it, programming is hard. Once we’ve been doing it for a while,
      perhaps with a dash of Stockholm Syndrome, we forget how much pain
      growth we have gone through to get where we are.</p>

      <p>So what might you know, but have forgotten that you ever learned
      it? In this talk, I will share my experiences of working on a software
      project as a freshly-minted software engineer. I will detail what I
      struggled with, where everyone around me just kind of “knew”. At the

      it be nice if the language matched its elegance?</p>

      <p>Kotlin, the productivity-focused language from our friends at
      JetBrains, takes up the slack to make the experience leaner, cleaner
      and even more pleasant!</p>

      <p>Since the early days of mobile that we keep seeing new frameworks
      being designed to overcome one of the biggest challenges: * How can I
      develop for both Android and iOS? Although it’s initial promises, when
      we talk about performance, maintainability or even customization we
      keep discarding these solutions and we always choose native. Fast
      forward to the present, and now we have two new languages: Android is
      Kotlin first and iOS, Swift. And if you put them side by side you can
      see a lot of similarities between both what will ease switching
      between one to the other if you have to develop for both platforms.
      But what I told that you could just develop in Kotlin and run it
      seamlessly on all devices? Here comes Kotlin Multiplatform!</p>

      не могли все предсказать - инструмент получился куда более
      универсальным, чем ожидалось. На нем можно делать даже библиотеки и
      приложения для науки! Об этом и поговорим.</p>

      <p>For several years now, that we’ve been trying to find new solutions
      on how we could develop a single project and run it on all platforms.
      We’ve been seeing all types of solutions: some are web-based, others
      require you to learn a new language, and others even may require that
      you pay a monthly fee to use. It also comes with the drawback that all
      your UI depends on the framework implementation. So, if there’s a
      native update you’ll need to wait until someone rewrites the widgets
      for you to update your app.</p>

      <p>Kotlin multiplatform gives us a new solution. It focuses on sharing
      your business logic across all platforms, leaving the UI to be
      implemented natively. Since it’s Kotlin, you can take full advantage
      of its language features - concise, safe, etc. Moreover, if you’re
      coming from android you might already be familiarised with Kotlin and
      even if you’re an iOS developer you’ll see that it’s quite similar to
      Swift.</p>

      <p>How do I create libraries for Kotlin Multiplatform projects? Kotlin
      lets you share common code between different target platforms, but by
      default only a limit set of platform-agnostic APIs are available to
      the code. As Multiplatform development really starts to take off,
      there must also be a robust ecosystem of third party libraries
      available to application developers.</p>

      <p>I’ll talk through what it looks like to create such a library,
      drawing from my experience building and maintaining one of my own
      starting in the early days of Kotlin/Native. We'll talk about how to
      find shared abstractions around different platform APIs, how to handle
      the fast-paced evolution of this environment, and what this all felt
      like as a first-time library developer. When we're done, you’ll be
      ready to leverage the growing ecosystem as well as make your own
      contributions.</p>

      <p>If you're still struggling to start using Kotlin in your Android
      Apps, this is your best chance! I'll cover the concepts and ideas that
      you need to start using it, and you'll lose the fear to learn a new
      language.

      Because Kotlin is so easy to learn and so enjoyable, that you'll never
      look back to Java again.</p>

      <p>Here are some things we will cover:</p>

      <p>- Intro to Kotlin

      - Create a new project

      - Funciones

      - Variables

      - Classes

      - Properties

      - Data Classes

      - Extension Functions</p>

      <p>Key learning concepts:

      - How to create a new Android Studio project using Kotlin

      - The basics of the Kotlin language

      - How they compare with Java and how Kotlin will boost your
      productivity</p>

      <p>Recommendations for attendees:

      - Basic knowledge of Android development using Java

      - 2 screens, to be able to see their own Android Studio and the
      streaming at the same time</p>

      <p>Most Android developers are familiar with Kotlin and use it every
      day with great success (and joy!). But the bloodline of the language
      extends well beyond Android! From cross-platform development, to the
      desktop, to the web, to backends, Kotlin’s pedigree as a versatile
      language puts all us developers in a great position to leverage
      existing knowledge for a variety of tasks outside a mobile engineer’s
      comfort zone.</p>

      <p>In this session we’ll use Kotlin, Ktor and coroutines to write a
      backend for our splendid fictional mobile app product: PushBeat. After
      learning the basics of a RESTful API, we’ll see what Ktor takes care
      of for us, what features may be helpful for our mobile projects, and
      how little we actually need to learn to be a productive backend
      engineer in no time!</p>

  subject: Writing Kotlin Compiler Plugins with Arrow Meta

    __cdata: >

      <p>Writing a compiler plugin is an uncharted area for many. There is
      very little documentation. It requires a lot of scaffolding. With the
      introduction of Arrow Meta, writing compiler plugins just got easier.
      It's a library that provides a functional API for creating
      plugins.</p>

      <p>In this talk, we’ll learn about how to write and test compiler
      plugins with Arrow Meta. This library provides an API for source
      transformations, automatic code refactoring, and much more. We’ll look
      at main use cases from type classes, comprehensions, and lenses that
      are made possible with Arrow Meta. We’ll also look at how to test each
      use case</p>

      <p>Under the hood, Arrow Meta supplements the compiler by hooking into
      the various compilation phases. We’ll look at the architecture of
      Arrow Meta and how this works. We’ll also explore the potential Kotlin
      multiplatform support. By the end of this talk, you will have a tool
      that you could use to create plugins.</p>

  url: https://www.online.droidcon.com/emea-agenda
  description:
    __cdata: >

      <p>Many Android developers are working in Kotlin nowadays. On Android,
      your Kotlin source code gets compiled to Java bytecode, and eventually
      to Dalvik bytecode. How is the result different compared to starting
      from Java source code then? Is it compatible? Can it be as compact? Is
      it as secure?</p>

      <p>We'll look at the differences. We've extended our open source code
      optimizer ProGuard and our protection software DexGuard to fully
      support Kotlin. We'll now share our experiences and point out what can
      be important in your apps and in your libraries. We'll demonstrate our
      new open source tool to view the

      Kotlin metadata hiding inside your apps. We'll show how to optimize
      and obfuscate Kotlin libraries in such a way that they remain
      compatible in other Kotlin projects.</p>

      <p>Armed with this knowledge, you'll better understand your own Kotlin
      projects and you can tune them to create more compact and more secure
      software.</p>

    Why Exception Handling with Kotlin Coroutines is hard and how to master
    it
  url: https://www.online.droidcon.com/emea-agenda
  description:
    __cdata: >

      <p>Getting the “happy path” right with Kotlin Coroutines is pretty
      straightforward. On the other hand, handling exceptions appropriately
      when something goes wrong is not that trivial.</p>

      <p>In this talk, you will learn about the reasons for the complexity
      of exception handling with Kotlin Coroutines and about all things you
      need to consider to appropriately deal with occurring exceptions.</p>

      <p>You will learn when you should use a conventional try-catch clause,
      and when you should install a CoroutineExceptionHandler instead.</p>

      <p>You will also learn about the special properties of top-level
      Coroutines when it comes to exception handling and how they differ
      when they are starting with launch and async.Furthermore, you will
      learn all about the exception handling peculiarities of the scoping
      functions coroutineScope{} and supervisorScope{} and why you should
      re-throw CancellationExceptions to avoid subtle errors.</p>

      <p>This talk is for developers that are already familiar with the
      basics of Kotlin Coroutines but still struggle to understand how
      exception handling works in detail. By the end of this talk, you will
      have a better understanding of how exceptions are treated by the
      Coroutines machinery and how you can handle them appropriately.</p>

      the classic game Breakout.</p>

      <p>Being massive TypeScript fans, it would always be their language of
      choice when working on JavaScript platforms. They didn't feel the
      drive to switch to other languages that transpile to JS such as Fable
      (F#), Scala.js, or even KotlinJS, as they always saw Kotlin on the JVM
      as the solution to a problem, the problem being Java.</p>

      <p>In this talk the dynamic duo will go out of their comfort zone and
      recreate a Breakout clone for the browser using KotlinJS.</p>

      <p>They will make use of React, Redux and use React Three Fiber for

      <p>KOTLIN is the new star amongst programming languages.

      <p>But the true story behind the success of Kotlin is developer
      convenience. Kotlin is designed to be as much like Java as possible
      where it makes sense, and as different from Java as possible where the
      design choices of Java get in the way.</p>

      <p>Kotlin has many features that are leaps and bounds ahead of Java.
      However, its primary target platform being the JVM, all of these
      features still need to compile to the same bytecode as Java does. This
      is a look at how a variety of interesting Kotlin features are compiled
      to bytecode, and what their Java equivalents would be. Even though
      Kotlin abstracts away much of the virtual machine and the original
      feature set of Java with its own features, it’s still important to
      know what your Kotlin code compiles to. Not only can this knowledge
      give you the power to optimize your code, but it will also help you
      avoid subtle bugs that would otherwise be near impossible to track
      down.</p>

      <p>Kotlin und Arrow, eine Kombination zum Schweben auf der Cloud.
      Anstatt uns durch den objektorientierten Dschungel von Schichten und
      Klassen zu kämpfen, können wir die Ausdrucksstärke des funktionalen
      Programmierens nutzen. Über dem Wirrwarr sind wir endlich frei, uns
      auf die Business-Logik zu konzentrieren. Wir erhalten kurzen und
      eleganten Code, der besser zu testen und verständlicher ist. Als Bonus
      ist die Verwendung von reactive-Techniken und Parallelisierung
      praktisch geschenkt. In dem Vortrag werden wir auch noch einmal das
      funktionale Paradigma betrachten. Anschließend steigen Sie im Live
      Coding voll in den funktionalen Entwurf ein und entwickeln eine kleine
      Spring-Boot-App. Natürlich funktional!</p>

      <p>Kotlin hat Java unter Android als bevorzugte Sprache abgelöst. Auch
      im klassischen Backend gewinnt die moderne, funktionale
      Programmiersprache immer mehr Freunde. Besonders interessant ist aber,
      dass Kotlin auch für den Bau nativer iOS-Apps verwendet werden kann.
      Wie das funktioniert, wird in diesem Vortrag auf entwicklerfreundliche
      Weise dargestellt. Sie erfahren, was genau Kotlin/Native eigentlich
      ist, worauf man bei der Benutzung achten sollte, was schon gut klappt
      und was (noch) nicht. Anhand einer kleinen, aber vollständigen App
      werden wichtige Vorgehensweisen und Konzepte vorgestellt.</p>

      this talk is for you. Effective serverless architectures require less
      backend code, less complexity, less risk, and less tech debt. But how
      is that possible? This talk aims to answer that question for you.</p>

      <p>Serverless application design is becoming more and more prevalent.
      Now is the time to understand this powerful shift in backend

      <p>Domain Specific Languages eignen sich seit jeher, komplexe

      Vermeidung redundanten Codes und reduzieren den Blick auf die
      wesentlichen Aspekte der Domäne. Der Vorteil interner DSLs gegenüber
      externen ist, dass sie sich direkt in einer Host-Programmiersprache
      entwickeln lassen. Kotlin bietet dafür mit seinen kompakten
      Sprachmitteln eine ideale Basis. Dieser Vortrag zeigt anhand konkreter
      Codebeispiele die Grundlagen zur Erstellung eigener DSLs mit

      Über Test-Dispatcher und -Scopes ermöglicht es Kontrolle über die

      <p>Collections are among the basic building blocks for writing code.
      Frequently used collections such as List, Set, and Map are designed to
      serve a basic fundamental purpose, but sometimes these collections are
      not enough and developers will extend them to add new functionality.
      In this session, Nikhil will extend the Map data structure to create
      two new collections called as a bag (MultiSet) and a multimap
      (MultiValuedMap). But does just extending a collection mean that the
      job is considered complete? Often it is not enough. Nikhil will
      explain the audience the basics of creating a new collection, adding
      new APIs, the salient aspects of the new collection, and the various
      knobs and controls required in order to make it safe and usable. This
      talk is 100% hands-on demo with no slides and using TDD approach. All
      the implementations done using only the JDK data structures and no
      external libraries. After this talk the audience will understand the
      thought process which needs to be put in while extending and creating
      new data structures, the helpful API which needs to be added and the
      safe guards which need to be put in place to help the users.</p>

  description:
    __cdata: >

      <p>With my current project, we have a hackday per sprint. During one
      of those hackdays, I discovered Kotlin's suspend functions. Functions
      that look exactly the same as normal functions, but by adding the
      keyword 'suspend' to them, you can start, pause and resume those
      functions without blocking. It seems like magic! Only if you don't
      know how it works under the hood of course. The pausing and resuming
      is done by coroutines, a concept I had not heard of before. That's why
      I spent some time reading and experimenting with Kotlin coroutines. I
      learned a lot about coroutines vs threads, blocking vs non-blocking,
      parallelism, concurrency and continuations. In this talk I would like
      to share what I have learned.</p>

  description:
    __cdata: >

      <p>This session shares notable changes in the Java ecosystem starting
      from Java 8 all the way until Java 14. No vendor-specific changes or
      enhancements are covered.</p>

      <p>Given the breadth of the topic and a time limit, this session will
      only cover the most notable or impactful changes.</p>

      <p>For instance, Java 9 introduced 150 new features: Java 9 changes
      focus on programmatic/syntactic changes for most part but will cover
      the new Java Module system JPMS, since it makes a huge impact for
      library developers.</p>

      <p>Similar constraints apply for Java 10, 11, 12, 13 and 14. However,
      post-Java 9, the release cadence of 6 months has greatly reduced the
      number of features delivered making the content more viable to present
      a larger percentage of changes.</p>

      <p>Java EE has been re-branded to Jakarta EE and moved to truly open
      source governance under the Eclipse Foundation. This session overviews
      what this means, offers a brief tour of the first release - Jakarta EE
      8, explores current state and looks to what the future might bring
      including some key challenges. We will also discuss how these
      challenges can be overcome through active community engagement.</p>

      <p>The technical contents of Jakarta EE 8 is mostly the same as Java
      EE 8 - it solidly enables HTTP/2, Server-Sent Events (SSE), JSON and
      aligns the platform with Java SE 8. It includes a much awaited
      security API overhaul as well as a slew of critical updates to APIs
      like JSF, JPA, JAX-RS and CDI. The true difference is how Jakarta EE
      is evolved in the open.</p>

  description:
    __cdata: >

      <p>gRPC is a technology that allows you to call server side logic from
      any platform using protocol buffers. What are the libraries available
      that allow you to create and consume gRPC services using coroutines?
      What are the debugging and monitoring tools we could use for gRPC?</p>

      <p>In this talk, I will share with you how to build a gRPC server
      using the gRPC-Kotlin library. We’ll explore how to use protocol
      buffers to define different types of rpc calls that are unary and
      bidirectional. On the client side, we’ll also use this library to
      consume our gRPC service. gRPC-Kotlin provides an API that uses Flows
      to make rpc calls. We’ll explore how it works internally. For each rpc
      call we implement using coroutines, I’ll show you how to unit test
      it.</p>

      <p>We needed to validate our use cases with tests:

      - that specify the user intents, not the technical details

      - that are human-readable (but without regex tricks)

      - that verify our hexagonal architecture running both end-to-end and

      in the domain only

      - that can guide our architecture like unit-tests are driving our
      design</p>

      <p>This talk is about how we solved these problems with the DDT
      approach

      and how you can apply this technique on your own backend application.

      A demonstration with live coding will show how to write them and use

      it to drive the development.</p>

      live-coding. Staring out with a simple rest service he will transform
      a CompletableFuture based endpoint into a Coroutine counterpart. He
      will rebuild a ServerSentEvent stream endpoint written with Reactor’s
      Flux with a Kotlin Flow and show you how Channels can be applied to
      broadcast information between Flows. He will finally explain how
      existing CompletableFuture or Flux/Mono based api’s can easily be
      ‘lifted’ into Coroutines allowing different reactive libraries to be
      used in a straightforward synchronous way without losing their
      asynchronous, non-blocking characteristics.</p>

      <p>Если вы писали многопоточный код, то знаете, что сложно написать
      его корректно сразу. Для тестирования обычно пишут стресс-тесты,
      покрывающие лишь некоторые опасные сценарии исполнения. Но часто для
      поиска ошибки такого подхода оказывается недостаточно. Для решения
      этой проблемы был создан lincheck — пока единственный инструмент в
      мире JVM, позволяющий удобно тестировать корректность (обычно
      линеаризуемость) многопоточного кода.</p>

      <p>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.</p>

      <p>Kotlin, as well as other languages like Scala or Groovy is
      developed (echm, hacked, eckm) over JVM. We all enjoy

      features like extension methods or strict null management that does
      not have corresponding functionalities native to

      JVM. How does that affect performance?</p>

      <p>In this talk, we will explore how Kotlin and its features around
      multiplatform projects can help tackle tasks around writing systems
      that are distributed across multiple platforms, such as server-client
      applications. In particular, we will look at how Kotlin for JVM and
      Kotlin/JS can play together, allowing us to share models, business
      logic, and most of all knowledge. We will get a broad overview of
      creating, managing and building such applications – all from within a
      single Gradle project, staying type-safe, and utilizing common and
      platform libraries.</p>

      <p>We'll also briefly talk about how we at JetBrains employ these
      Kotlin multiplatform features to prototype new ideas and realize
      products – from hackathon projects to JetBrains Space, our integrated
      team environment</p>

      <p>One of the reasons Kotlin has proven so popular is its wide array
      of abstractions and constructs. But pattern matching, a popular
      feature that in other languages allows us to easily inspect data and
      act accordingly, is currently missing.</p>

      <p>This talk aims to explore the possibility of adding pattern
      matching to Kotlin. It will go through why and how it could be done,
      from adding it to the actual language to using a compiler plugin (much
      like kotlinx.serialization works).</p>

      <p>Pluggability is hard. Many software projects avoid it by all means
      possible. Many try to contain it in the smallest possible scope. We
      believe that developers are creative and have specific requirements
      for their documentation engine. Some of them want to be able to render
      their docs in javadoc-compatible format. Some of them want features
      like a full-text search or runnable code snippets inside of the docs.
      And there are some that need features that we’ve never even thought
      about. To satisfy all of them, we decided to embrace full
      pluggability. And we decided to make pluggability fearless, so anyone
      can mix and match existing plugins or easily create new ones from
      scratch, without the fear of breaking anything.</p>

      <p>In my talk, I would like to tell you how we decided to redesign and
      reimplement Dokka from scratch. I will introduce you to all the
      dangers and risks of pluggability and tell you how we mitigated them
      by design, grounded in strong guarantees. Finally, I want to show how
      easily and how much you can do with your old, boring documentation
      using new Dokka.</p>

      to headaches when we were manually configuring profiles, teams, repos,
      blogs, chats and checklists. We since solved this by using the Space
      HTTP API to create an automated pipeline. Today anyone can configure
      any workshop in a matter of minutes. This talk will walk you through
      the code behind this pipeline. In addition to the Space API itself, we
      will be covering OAuth, the Ktor HTTP Client, DSLs, Functional
      Patterns and Integrating Testing.</p>

      <p>The Android developer community seems pretty excited by the

      must learn. One of the most important is Kotlin/Native’s state and
      concurrency model. While the Kotlin/Native state model is conceptually
      simple, it is also different, and will cause some confusion if you

      <p>“Multiplatform” is a paradox._

      It makes things both easier and more complicated at the same time.

      It’s the opposite of what most _expect_ or think they need... And also
      the solution to their _actual_ needs.

      It's also more than just a technology—Ah, and you're already doing it
      (inefficiently)!</p>

      <p>Then what is it, really?

      And why would Kotlin be any different than all those other failed
      multiplatform tools?</p>

      <p>One short answer is: **Kotlin _works_ on multiple platforms, but is
      _not_ multiplatform.**</p>

      <p>Sounds like another paradox?

      <p>In this talk, we demonstrate how the http4k library leverages its
      “Server as a Function” roots to enable writing apps which can be
      test-driven at all levels of the Testing Pyramid, using a set of tools
      derived from decades of experience testing backend applications to

      <p>When creating a game, you want your game to be available on all
      platforms to target as many players as possible. Developing a game
      engine is a challenge: you have to deal with mathematical concepts,
      animations, player interactions... Creating an engine that runs on
      different platforms is even more challenging. Is Kotlin and
      Kotlin/Multiplatform could be the right tool to build this kind of
      engine? Let's check this out together.</p>

      <p>Message for you, so you can already be aware what you can expect
      from this session:

      Using existing Java game engines, you can create a game that runs on
      the JVM, in a browser or on Android and iOS. But it requires some
      complex tooling, when tools are available for the platform you're
      targeting.</p>

      <p>This session is about the creation of a game engine that runs the
      same way in a browser, in a JVM, on iOS or Android.</p>

      <p>Throughout this session, attendees will learn:

      - Basic matrix computation needed for 3D engine;

      - Basic game development concept: drawing shapes on screen, dealing
      with skeleton animations;

      - How to convert a pure Kotlin/JVM library into a Kotlin/Multiplaform
      library;

      - Example of use of Kotlinx.serialization to share game content
      between each platforms;

      - What didn't work while budding this kind of engine, like building a
      common API over heterogeneous game engine; or converting a java engine
      into a Kotlin one;

      - The challenges to build a game engine on the top of the Open GL API.
      (Open GL is a 3D API available almost everywhere: WebGL (browser),
      Open GL ES  (Android / iOS - deprecated), Open GL (JVM / Native);

      - Issues encounter to build such engine on different platform: name
      forbidden in Kotlin/JS (val input -- package input conflict). Taking
      very seriously the naming and the abstraction on the common.</p>

      <p>The JavaScript target for Kotlin bears huge potential for bringing
      the language we love to the influential world of browsers and JS
      engines. Since its first release with Kotlin 1.1, Kotlin/JS has
      evolved and keeps maturing.</p>

      <p>In this talk, we'll explore the benefits and challenges when it
      comes to targeting the JavaScript world with Kotlin. From standard
      libraries and simple DOM manipulation to building full React
      applications: guided by code and configuration examples, we will get
      an impression of the technology and its interoperability with an
      exciting ecosystem – including the freshest changes and additions for
      Kotlin 1.4 and going forward.</p>

      <p>We'll also see how Kotlin libraries support development of
      Kotlin/JS applications, even beyond the browser – from concurrent
      applications with coroutines to painless communication supported by
      kotlinx.serialization. In the same context, we will also look at
      interesting and useful constructs we can create for Kotlin/JS in
      multiplatform projects.</p>

      <p>Microservice architecture is now a huge trend. All big
      organizations with millions of users are doing microservices. This
      means they have lots of channels of communication between services and
      need to send and get much data. At some point, you can find yourself
      in a situation where your current approach doesn’t provide you with
      efficient communication, you pay more, wait more, lose more etc. Maybe
      it’s time to look at gRPC… gRPC is asynchronous by its nature. But old
      API, Java infrastructure and verbosity make people write lots of noise
      and break their beautiful minds to make things done. In Kotlin we have
      awesome coroutines concept. So async gRPC and coroutines could be a
      perfect match! Let’s discover if this is possible. In this talk, we’ll
      learn how to build microservices using gRPC with minimum pain. We’ ll
      discuss the pros and cons of this approach, what can be improved, what
      should be added.</p>

      <p>RainbowCake is an architectural framework built on top of the best
      & latest of Jetpack and Kotlin. One of its core features is its view
      state and view event handling mechanism, which is somewhere between
      MVVM and MVI, and is powered by LiveData. In this talk, we’ll first
      look at the client side API of the framework, and the design decisions
      that went into it. Then, we’ll dive into how all of this is
      implemented under the hood by customizing LiveData. While the talk
      discusses this specific framework, the ideas in it are universal and
      can be used independently in any project.</p>
