#### **Techniques for a faster JVM start-up**

During this session, I will discuss a few techniques about how to improve the JVM start-up time for any application running on the JVM, independent of the programming language. These techniques could be applied in any project, in general without code changes. You can use the same techniques to speed up the JVM start-up time for your applications (both in development and production environments). Main topics:
\- when the JVM start\-up matters \(i\.e\. for what types of applications\)
\- Application/Dynamic class\-data sharing in HotSpot JVM
\- shared class cache in Eclipse OpenJ9
\- few handy JVM flags
\- hands\-on demonstration \(including benchmarks results\)
\- \(optional\) Ahead\-of\-time \(AOT\) compilation The JVMs included in this talk are OpenJDK HotSpot\, Eclipse OpenJ9 and Graal VM

**Rust for Java Developers**
Let's talk about Rust, the next programming language trying to do better than C++. Rust hit the top spot as Stack Overflow's most loved programming language for seven years in a row, and gets developers interested world-wide. But what's the deal with Rust? What are its use-cases? How does Rust keep its promises of zero-cost abstractions, memory safety without garbage collection, and fearless concurrency? In this session, we will go into the nitty-gritty details, compare Rust to what we know from other programming languages, and take a good look at its unique features.

Stefan Baumgartner is a software architect working at Dynatrace. He is the author of “TypeScript in 50 Lessons”, published by Smashing Magazine.
