<description>
<![CDATA[
<p>Do you want to start your journey with Kotlin? Is your team introducing Kotlin, you know you need to learn it, and you don't know where to start? In either case, this talk should be a great help. I had a bunch of surprises when I moved from Java to Kotlin, and I want to tell you all about them. I’ll show you Java vs. Kotlin examples and explain why the creators of Kotlin made these choices.<p>

<description>
<![CDATA[
<p>We have a lot of code experience to share as an Android developer using Kotlin or a Backend developer using Java.<p>
<p>When we talk about backend technologies, we have a lot of languages/frameworks like Go, Java, Python, etc. But when we talk about Kotlin as a backend language, it might raise a lot of eyebrows<p>
<p>But let me try to convince you that Kotlin is definitely a good choice for Backend!<p>

<![CDATA[
<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>

<![CDATA[
<p>Jetpack Compose is the most interesting UI framework for Kotlin programmers.</p>
<p>Compose started out as a declarative Android UI layouts-as-code library decoupled from Android OS releases. Similar to SwiftUI, it lets developers declare user interfaces as a tree of widgets that updates as your app state updates.</p>

<subject>Co-routines: When to Use and When to Avoid</subject>
<url>https://mobileweek.co/conference/</url>
<description>
<![CDATA[
<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 so far.</p>

<![CDATA[
<p>Modern serverless technologies are coming in different sorts and ranges. But there is no doubt that it’s bringing significant innovation in the application development space. And today’s developer is trying to grasp the best approach for each cloud vendor. And often she faced with following questions</p>
<p>How do I start? Which platform supports my language of choice?
How do I manage the application state?
How do I integrate with existing «legacy» systems? In this presentation, Viktor Gamov will walk you through the setup and deploy a serverless application that includes event functions, services, data streaming. For event functions and services we will use the open-source Knative project on Kubernetes. For data streaming, we will use Apache Kafka.</p>

<description>
<![CDATA[
<p>KSP (Kotlin Symbol Processor) 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. In my talk I would like to present several cases (such as Dependency Injection, e.g) of using KSP in Kotlin Multiplatform for both Android and iOS.</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>

<description>
<![CDATA[
<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>

<description>
<![CDATA[
<p>Google DeepMind's AlphaGo was an extraordinary breakthrough for Artificial Intelligence. The game of Go has 1.74×10^172 unique positions and is about a 'googol' times harder to calculate than chess. Experts thought it would take at least another decade before A.I. would be able to beat the best human players. So how did DeepMind tackle this problem? What algorithms did they use and how do they work?</p>
<p>During this talk we'll explore several algorithms that can be used to make a program play games, we'll start simple (Tic Tac Toe) and as the games get harder, the A.I.'s need to become smarter.</p>

<p>Kotlin is a JVM-based language, and many of its features are borrowed from related languages like Groovy and Scala. It is designed to work well with Java and to be easy for existing Java developers to learn. Nevertheless, Kotlin contains several features and practices 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 without a static keyword, overriding properties as well as functions, defining objects rather than classes, the Unit and Nothing classes, why const is useful when you already haveval for final, and more.</p>

<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>

<description>
<![CDATA[
<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>

<description>
<![CDATA[
<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>

<description>
<![CDATA[
<p>Ok, Kotlin is cool and fun. It's even better with built in coroutine support. As Kotlin is getting popular in backend 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>

<subject>Why you should use Kotlin – and how a pitch changed everything!</subject>
<url>https://jspring.nl/sessions/the-miles-stones-towards-a-kotlin-movement/</url>
<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>

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

<description>
<![CDATA[
<p>A new Kotlin functional library to serialize/deserialize Json fast and safely without using reflection, annotations, or code generation.
With Kondor you need to define how the Json would look like for each of the types you want to persist, using a high-level DSL.</p>
<p>In the talk, I'll present the reasons why I wrote yet another Json parser library. Then I'll show how to use it and how it solves some problems than other libs. I will also cover the advantages offered by the functional programming approach for writing a parser/serializer.</p>

<subject>Kotlin Jupyter API: интеграция Kotlin-библиотек с Jupyter-ноутбуками</subject>
<url>https://www.meetup.com/KotlinMoscow/events/278027639</url>
<description>
<![CDATA[
<p>Занимаясь прототипированием, data scientist хочет, чтобы ничто не отвлекало его от моделей и данных. Он хочет, чтобы данные без лишних усилий отображались в виде диаграмм и таблиц, все необходимые зависимости подключались по возможности просто, а тулинг помогал лучше ориентироваться в исследуемых данных.
В этом докладе я расскажу, как Kotlin Jupyter kernel позволяет авторам библиотек делать их удобными для использования в ноутбуках. Рассмотрим отображение объектов, pre-evaluation и post-evaluation коллбэки, а также доступ к результатам выполнения ячеек через reflection напрямую из библиотек. Поговорим о том, что такое Kotlin REPL Compiler и причём тут implicit receivers, о разрешении зависимостей и класслудерах. Посмотрим, как библиотека Dataframe эксплуатирует Jupyter API для обеспечения типобезопасного доступа к данным, а KotlinDL - для отображения структуры нейросетей.</p>
