GraalVM night! - Singapore Java User Group

== Part 1: GraalVM for Java developers (Oleg Selajev)
GraalVM is a high-performance virtual machine for dynamic, static, and native languages.
GraalVM supports Java, Scala, Kotlin, Groovy, and other JVM-based languages. At the same time, it can run the dynamic scripting languages JavaScript including node.js, Ruby, R, and Python.
In this session we'll talk about the performance boost you can get from running your code on GraalVM, look at the examples of running typical web-applications with it, enhancing them with code in other languages, creating native images for incredibly fast startup and low memory overhead for your services.

GraalVM offers you the opportunity to write the code in the language you want, and run the resulting program really fast.

== Part 2: GraalVM for Sustainable Software Development? (Adrien Nortain)
With the crazy pace of digital transformations and hardware releases, introducing sustainability in our software solutions is becoming more and more of a challenge.
Unfortunately, our planet has limited resources actually needed to build and run IT products.
Therefore, if we want to continue adding value to the IT market, Green IT must not be considered a hobby or a trend anymore but a necessity.
Now, when we talk about GraalVM, we usually focus on its Native Image feature.
And while the technology itself is impressive, one must wonder: is it really helping writing sustainable software? What key aspects of a language / framework should we focus on in that regard?
Let’s dive in and look at GraalVM from a different perspective!
