ABSTRACT
Java never went away, but it’s having a renaissance. After some initial teething pains on the cloud (too big, too slow, too hard to configure) a new breed of Java frameworks are changing everything.
In this talk, Holly will introduce Quarkus and then delve into some of the advanced features you might not know about. She’ll cover native binaries, what makes Quarkus super-fast running on the JVM, TDD with Quarkus, and Quarkus’s carbon footprint. The talk includes some theory (what underpins Quarkus’s surprising speed?) and also live demos (does Quarkus really start faster than a light bulb? What does an integration testing flow with Quarkus look like?) [...]

I had the "pleasure". My conclusion: it is just a worse and more complex Spring Boot. The compilation features are not useable in real life business applications due to compatibilty issues and most other features make it just harder to use. It works, Quarkus is OK, and it is a very good idea if you want to write rather simple, technical modules in Java (instead of Go or the like) but else, it will not be your friend.

[@mubashir3]

Java may be going the way of COBOL. Sure people still use it. And will continue to use it for years to come. But, mostly in legacy projects. It is very rare to see a new startup pick up Java.

[@arnoldhau1]

Yes but most software developed is not for startups. It is in banking, government, industry and so on, and those are quite conservative. Therefore, a lot of new Business software is still written in Java. And while Java is outdated and not great, it is really unfair to compare it to COBOL with was just a horrible language. Java would not be my choice, but still I end up doing all projects in Java, as it is mandated by most clients. Best case you can use Kotlin, but usually not.

[@MrKar18]

Netflix for example and even Apple is mostly a Java/Kotlin shop. Your assumptions show that you lack vast experience. In terms of maintenence of applications, almost every enterprise prefers Java. Easy to find people to work with, easy to understand. Language evolves and java has evolved better. Startups don't stay startups forever!

I will take Java, the JVM and its eco system every time over Python, JavaScript, Golang

[@arnoldhau1]

@@MrKar18 Apple? Really? I thought they use Objective C , C and Swift?

[@arnoldhau1]

@@bigdlamz Ok and why? Golang is not ideal for business applications, but Python? And you can not avoid Java- or Typescript, as you need it for the UI, usually. In all Java applications I developed in the past 10 years the UI was developed that way.

No

[@pbdagr]

ok

Quarkus - says nobody.
