**Abstract 1:**

IntelliJ IDEA’s refactoring support is second to none, but the Refactor This menu only has 9 items. Where is all the power hiding? Join **Dmitry and Duncan** on a whistle-stop live-coding tour of our favourite IDE’s invisible refactorings. Marvel as Alt-Enter reveals refactorings before your very eyes. Gasp as they change depending on context. Wonder how completely different they can be simply by moving the cursor one character to the left or right, and feel the tension mount as they approach the deadline. **Can they really show more than one refactoring a minute**?

**Abstract 2:**

**Project Arrow** may be unknown to some, but It is a project that covers many important aspects of **functional programming** to build resilient and performant services. I want with this talk to share my experience but instead of talking about Telecom, I want to include this talk in the context of a **spaceship and data transmission** throughout all the operating systems. I cannot of course show the code of any company I have worked for and so, to share my knowledge and experience I will create a spaceship scenario. For that, I will use the **Ktor** as an example for services completely implemented in **Kotlin**, with Exposed for database access and completely reactive. You should come out of this session knowing all the major aspects of Project Arrow, including foundation knowledge, some advanced features, and a few extras.
