<description>
<![CDATA[
<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>Abstract for Android Architecture Design with Koin
Koin (https://insert-koin.io) is a pragmatic dependency injection framework for Kotlin/Android developers, well known for its ease of use. In this session, I propose to see together how we can structure our components, for the following topics:<p>
<p>Classical Components in MVP, MVVM
Dealing with Scopes
Jetpack Navigation
Jetpack Compose
Integrating with Multi-Platform<p>

<subject>Web applications development with Kotlin</subject>
<url>https://www.meetup.com/stockholm-jvm-jug/events/284463090</url>
<description>
<![CDATA[
<p>Kotlin was originally designed as an alternative JVM language. Meaning that Kotlin can be used anywhere JVM runs and of course, we can use it with various JVM frameworks to build web applications. In this presentation, Anton is going to make a brief overview of the Kotlin programming language with the assumption that you're fluent in Java. We will take a look at some of the language features that make Kotlin so exciting and see how it can be applied with the Spring Boot framework.<p>

<![CDATA[
<p>A CS degree is not a requirement for software developer roles. Nor should it be! I have worked with biologists, psychologists, and even a historian, who all were excellent coders. And that's great! Diversity 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 introduces you to the remarkable people who came up with these things. They ended wars, sent rockets to the moon, and were made into Lego minifigs. Who said computer science is boring?<p>

<url>https://cfp.devoxx.fr/2022/talk/PIH-9907/Ligne_de_Commande,_Kotlin_et_Star_Wars_:_Presenter_PicoCLI_avec_le_combo_gagnant</url>
<description>
<![CDATA[
<p>picoCLI est une librairie qui permet de créer simplement et 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>

<description>
<![CDATA[
<p>Helidon is a brave, small but powerful open source framework for writing microservices. If you need to get the maximum performance – 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 experience will easily let you start programming in Java style. 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 readable.<p>

<description>
<![CDATA[
<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>

<description>
<![CDATA[
<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. Come and learn what's new and exciting!<p>

<p>The Kotlin typing system is amazingly designed. It was designed and constantly improved for years, and it was built based on experiences from other typing systems. As a result it gives us very comfortable nullability support, type inference, universal guards, and much more. In this presentation, we’ll dive deep into Kotlin typing systems and how small design choices lead to a better programming experience.<p>

<url>https://fosdem.org/2022/schedule/event/advanced_multiplatform_dependency_injection/</url>
<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>

<description>
<![CDATA[
<p>kalasim is a discrete event simulator written in pure Kotlin that enables complex, performant, dynamic process models. It provides a statically typed API, dependency injection, modern persistence, 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>

<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>

<subject>KSP and Plugins. Optimizing Kotlin Multiplatform common code</subject>
<url>https://fosdem.org/2022/schedule/event/ksp_and_plugins/</url>
<description>
<![CDATA[
<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>

<description>
<![CDATA[
<p>If the one thing that has kept you from the JVM has been Java, you 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 developer.<p>

<subject>Архитектура математических вычислений на Kotlin</subject>
<url>https://jokerconf.com/talks/architecture-of-math-calculations-on-kotlin/</url>
<description>
<![CDATA[
<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>Если после релиза open source-библиотеки у вас возникал вопрос как же правильно её поддерживать и обновлять, то этот доклад для вас. Мы поговорим о совместимости между разными версиями и различными инструментами, которые помогают разработчику не сломать её. Также затронем тему эволюции API, как лучше всего добавлять новые функции в библиотеку и отключать старые. Большинство тем будет проиллюстрировано примерами из всем известных библиотек на Kotlin, таких, как kotlinx.coroutines и kotlinx.serialization.<p>

<p>Spark — самый популярный инструмент для построения конвейеров данных. Каждый дата-инженер знает Spark, бла-бла-бла... Отлично, но Spark всего лишь распределенные Java Streams, так? Но тогда, как это работает? Получается, что нельзя просто вызвать «flatMap» или «groupBy» на удаленную машину. Вступает Codegen! Заинтересовались? Приходите и узнайте больше!<p>

<description>
<![CDATA[
<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, преимущественно использующей Kotlin для backend-разработки.<p>

<description>
<![CDATA[
<p>In this session, we look at how companies can share business logic between platforms while only writing code once and then running it on all platforms. We look at how such an architecture reduces risk, increases productivity and how this can be achieved using a single programming language. We look at hybrid approaches that might be more pragmatic in existing teams and the benefits of going this route. We also look at why Kotlin is such a compelling choice for achieving architectural nirvana.<p>

<![CDATA[
<p>Switching from Java + Dropwizard to a Micronaut + Kotlin stack is the topic of this talk. What does such a transition mean? How much new stuff does a developer need to learn until he/she is similar productive than before?
I will show you what I like at most in Kotlin for instance the basics like null safety, data classes or scope functions or the simplification when writing lambdas or using Kotest and Mockk for unit tests.
In addition to that I will explain some powerful and easy to use Micronaut features which covers the usage of OAuth, multi-tenancy and building simple integration tests.<p>
