... a good thing. Then we'll see how we can properly get our flows to run on multiple coroutines.

Thumbnail Image - "Context Preservation and Multi-Coroutine Flows" over an IDE with Kotlin code.
Kotlin's flows really become fun once we start putting our emitters and collectors on separate coroutines... but we can't just call `emit()` from inside a `launch` block, because of Context Preservation!
In this week's video, we'll see what Context Preservation is and why it's...

Yes, #Kotlin flows have a lot of familiar operators from the collection and sequence APIs, but since they run on top of coroutines, they also have many operators that you won't find in those APIs.
In today's video, I show off some operators that you'll only find on flows!

This #Kotlin update was easy to miss! You can now use `return` in expression bodies. On the surface, it sounds useless, but I put together this 6-minute video to show the reasons why it's actually an important update.

Concurrency + Mutable State = Risk
Kotlin's design of coroutines prevents a lot of problems, but not race conditions. It does give us some great tools to help, though! Here's a 9-minute video that covers what you need to know about each one. I hope you find it helpful!

Wow, that's a lot of growth in one year! 🎉
It's been a few years since I've worked on a Spring service, but the new Spring Debugger plugin in the latest @intellijidea.com looks really cool! Stuff like...
- Loaded vs unloaded beans
- Active vs inactive configs
- Debug beans at use site

Hey, Valère! Thanks for asking! My video editing is done in Davinci Resolve. Some of the annotations (basic lines and circles) are just my own hand-drawn annotations, but the ones that zoom in like that are plugins from MotionVFX. I believe the one in your screen grab is from mHowTo.

I'm not on my usual Windows machine here, but on Mac I get the println() output regardless of the dispatcher I choose.
Thanks for looking into it! For what it's worth, I'm using Windows here, and Ctrl+C copies just the selection for me.
