Zoom session where we will gather all the attendees, speakers, and program committee members and experts. We will sum up the highlights of the conference and chat with each other in an informal setting of a merry crowd, like in good old non-COVID times. The only difference is that it will be in Zoom, because now it’s time of COVID, unfortunately.

Alexander will tell in detail about his work in the Java Community Process (JCP) project and why BellSoft was chosen by the JCP Executive Committee.
When we talk about Data Science, Java as a tool for this work is the last thought. But! The time has come and it's time to make the distinction in DS. Separate experimentation from development. However, you'll say there are not many DS tools in Java! No longer! Artem will tell you how and what to use to work with data and build machine learning models.
Artem will tell you how and what to use to work with data and build machine learning models.
During this interview, Roman plans to look at the differences between Java and Kotlin, what each language has yet to improve, and how they plan to overtake each other.
Andrey will present a short version of his "Microservices. An adventure for 60 minutes" presentation and will tell about the main principles of choosing the size of microservices and provides reasons you can use in discussion with an architect.
Rise of the machines is coming or do we still have time to confront it? Tagir will speak out the burning question "will the program replace the programmer" and try to answer it.
IntelliJ IDEA added support for async-profiler for Mac and Linux a couple of years ago. They started using it and realized that they needed an async-profiler on Windows. During this session Kirill will tell you what difficulties had to be overcome in the process of porting async-profiler to Windows. The talk will be interesting for people who like native and low-level development and all sorts of OS-level stuff.
After a quick introduction to Kogito speakers will show with practical examples of how to build cloud-native event-driven business applications; to the point where applications can be even deployed in a serverless environment, through Knative. They will also show what challenges a distributed environment poses, and how we can deal with them.
