We’ll also be available for the live Q&A sessions. I know it’s a short notice, the event starts at 11:00 AM UTC today. So if you are not able to join, please register to receive a follow-up email with the links to the talk recordings.

Hi there, any tips on how to teach in Kotlin for starters? #education

hi, anyone have a canvas shell for kotlin?

how are people teaching Kotlin in the high school classroom? I'm planning on a Java mini course then go into Kotlin.

Hi everyone! Who has tried to teach Kotlin to high school students as thier first language? Can you share you experience?

Yeah. I love this channel! 🙂

Remember, Kotlin for Education webinar is now:

:android-wave: More opportunities to teach Android development with Kotlin! Check out the new Android app development curriculum from Google on the new educator landing page! • It’s an instructor-led curriculum for classroom learning (virtual or in-person) with an instructor delivering lectures on important Android concepts, and students receiving hands-on practice through codelabs. • The official course materials are now available and can be freely modified by instructors to adapt to their students’ needs. • This curriculum updates accounts for the most recent changes in the Android platform, from the release of the Android Jetpack libraries to Android development becoming Kotlin-first. • Instructors do not need Android or Kotlin experience to teach the curriculum, prior programming experience is recommended. • Android Study Jams program for teaching and learning in peer groups has become available to all developers today! This great content is now available publicly, so you are very welcome to start teaching Android development with Kotlin!

Can I use a course which was created with the EduTools plugin as a submodule inside another gradle project?

One thing on the edutools that I do (but isn't really supported nicely) is to use github classroom to host the course (student content). I want to get students used to using git(hub) as well. The experience could be a bit tighter

Please tell Google to update the code lab for jetpack compose https://developer.android.com/courses/pathways/compose It is not working now Because the code is old and there are many huge changes in the framework jetpack compose Google should update the code

Hey all ! I have recently visited a engineering college in my city and delivered a hour talk about adopting kotlin. I took them through small code comparison between kotlin and java along building for android. Talk went well and 40% students came forward to learn, they all know java basics. I have all my content ready. I didn't had a chance to ask a question in yesterday's webinar by @Rahul Pandey, so I thought to drop my query here. Question: 1. Should I teach kotlin and it's concepts for first week continuously and then start with android later? Or 2. Do both in parallel where-ever possible, like covering small topics in kotlin and build simple single screen app with android? By the way this students training will go for a month. Will students loose interest if I take first approach, they all right now belong to 3rd year graduation. What is your take on this, can anyone share any similar experiences in your teaching please.

Right now I was pointed in the direction of this video: and I would like to remark that this kind of inlini functions presentation is really harmfull (if someone knows the author, please tell her). Here is my comment under the video:

Using inline function everywhere does not improve performance, but on the contrary, decreases it because JVM inlining is better than manual inlining. Also, using inline everywhere significantly bloats the bytecode because it creates a copy of the code for each call. So please, PLEASE, do not recommend using inlines for optimizations. And it definitely should not be ever used in large functions. Performance optimizations like that should not ever be used without need and without profiler measurements.

In general inlines should not be used for optimizations without profiler measurements. My own measurements show that inlining large functions significantly decreases performance. So beginniers should stick to the functions in the standard library, which are already optimized by size and usage. Without additional considerations inline should be used only for reifications and non-local returns.

Hi. Can anyone help me please? I need to setup a completely offline IntelliJ projet with gradle and kotlin for our constrained school environment (No Kotlin installed, No Gradle, No Internet). I packed all kotlin dependencies into

libs/kotlin

but it still tells me, that

kotlin.jvm.internal.Intrinsics

is not found. You can find the repo here: https://github.com/emign/kotlinOfflineTest The error I struggle with is:

Could not perform incremental compilation: Could not connect to Kotlin compile daemon

🎓 The Kotlin for Education webinar starts tomorrow! @Sebastian Aignerwill demonstrate how Kotlin can be used to teach different computer science subjects. Please do share any questions or comments here, or tomorrow during the session. We really want to hear from you and answer your questions! Join the event on May 26, at 19:00 PM CET https://info.jetbrains.com/kotlin-webinar-may26-2021.html See you soon!

@Sebastian Aigner Where are the slide numbers?!

The slide "start simple" why not

fun whichColor(str: String) = if(str == "blue") Color.Blue else Color.Black

By the way, I intend to change the strategy for the next year. The "lectures" seems to be too boring for students in the age of recorded videos, so I intend to give tasks at the beginning of the semester and focus on the code review. Have anyone done that?

Is there any course to learn Kotlin ?

Ten years of Kotlin :kotlinnew: Hey, folks, we’re celebrating 10 years of Kotlin! Check out our and the page showing the language’s past, present and future!

Hello Kotlin Slack community 👋 Let me quickly introduce myself and share something with you regarding #education 🙂 The interesting information first: I am working on a series of educational Kotlin videos :kotlin-intensifies: My name is Jakob Löhnertz, I was born in raised in Germany, and I am living and working in the Netherlands nowadays as a software engineer at the Amsterdam-based online supermarket Picnic. I am a Kotlin fan since many years and use it a lot for large-scale personal projects. I decided some time ago to start an educational YouTube channel since I have a long-running interest in becoming an educator and I am originally self-taught in our domain myself. The YouTube channel is called The Self-Taught Software Engineer and covers everything from beginner programming courses to advanced material regarding specific engineering topics. My goal is to provide interesting and engaging, high-quality, educational videos to everyone interested in developing software – free of charge, accessible, and to the point! I specifically want to leverage my perspective from being self-taught myself to give a view onto the topics that something like university sometimes misses. But enough of the boring introduction, let me share why I am making this post here: Since Kotlin is my favorite programming language, from the start of planning the channel and its videos, it was clear to me that I will use Kotlin as the vehicle of explaining the subjects. Furthermore, I was planning from the beginning to specifically focus on educational Kotlin content as well! Therefore, I started a series titled Idiomatic Kotlin where I cover one topic that is specific to the language in each episode. The structure of the videos is based partially on explanations using slides and self-made graphics while a big focus lies on the real-world-esque code examples that I prepare with a lot of love for each episode to explain the topics on something that is more than just a two-line snippet that one would never encounter in the wild. I want to show the viewers how they would apply this in their day-to-day software development. All those examples I am also committing to a public repository on GitHub such that everyone can follow along, explore the examples, and even execute them locally to play around with them and truly understand the subject at hand. Today, I released the second episode and I figured this warrants making this announcement here. I presume that many people in this community already know most of the things that I am sharing. However, I'd be very happy for feedback, future episode suggestions, and if you liked it, that you share it with people that would benefit from the content. The first episodes were: 1. Scope Functions 2. Collections vs. Sequences Enough of the talking, I'll let the videos speak for themselves now. I hope you like them as I invest a lot of love into the preparation of the examples, graphics, and the presentation. Nevertheless, I am of course happy with any feedback 🙂 Also make sure to check out my other content (I already have two videos on IntelliJ IDEA), if I caught your interest. Here's today's episode Collections vs. Sequences () where I am explaining the differences between using collections and sequences within the Kotlin Collections API. I am covering what they are, when to use which, and what pitfalls are that one has to be aware of when using them. And this is where you can find the aforementioned examples: https://github.com/The-Self-Taught-Software-Engineer/Examples/releases/tag/idiomatic-kotlin%2F%2302_collections-vs-sequences Thank you so much for reading. Enjoy and get in touch with the channel and me!

It's me again 🙂 I produced a new episode of my YouTube series Idiomatic Kotlin. As promised, this one is about the Result mechanism (

Result<T>

) of Kotlin! For this one, I upgraded my production quality a lot (including the usage of JetBrains Mono font for code snippets 😉) and took the feedback that @altavir and others gave me to heart, to focus on brevity. This episode is lot more to the point with an auxiliary appendix video available in which I am going into more detail with a hand-made example again. Here's the new episode: Let me know what you think 👍

Hi everyone! I'm planning to teach #competitive-programming using Kotlin for the ICPC  in Sudan, and I was searching for a way to run Kotlin in a Notebook like Jupyter Notebook but online like Google Colab! Is there any way to do that now or it's underdevelopment?

Hi there, I'm giving this talk https://www.casus.science/events/casus-institute-seminar-bringing-data-automation-and-modelling-together-with-kotlin-by-holger-brandl/ next week in collaboration with @elect. I'd love to include some interactive tutorial part, where I would love to use https://play.kotlinlang.org/ in conjunction with one additional dependency:

implementation "com.github.holgerbrandl:kalasim:0.6.90"

. Is this possible, could you maybe help/support me with the setup?

Hi everyone, I work on Peloton's Tech Learning team and we're looking to bring in some educators to support our engineers who are learning Kotlin. Would love to chat with any educators here who would be interested in working with us on this!
