Pattern Matching: Small Enhancement or Major Feature?
At first it seemed to be just a small enhancement: the addition of "Pattern Matching for instanceof" (JEP 305) in Java 14. No more unnecessary casting after an `instanceof`, that ought to save us a few seconds a day! However, upon further investigation you'll quickly discover that pattern matching is not just an enhancement, but rather a vital puzzle piece in the grander scheme of things.
Why were switch expressions added to Java, for example? To make them support pattern matching in a later release! And why did Java 14 bring us records and did Java 15 contain sealed types? Because they could work really well with pattern matching in a later release! These new concepts are the foundation upon which advanced pattern matching features will be built.
So attend this session to get all caught up! You'll hear about type patterns, deconstruction patterns, nested patterns and even how pattern matching could improve serialization in the future. Live coding included, of course!
Battling your Biased Brain
Ever heard of the IKEA effect or the bandwagon-effect? In our efforts to delivering great software, there are numerous occasions where our brain tries to trick us. Don’t fall for them!
In this talk we will dive into some well-known and researched cognitive biases that impact our judgments in our day-to-day jobs as software creators.
When do they typically occur? And why are we falling into these traps from time to time?
After this talk you'll have a better understanding of how your brain tricks you, how to make better decisions and in the end how to deliver some great software.
A word of warning; during this talk you may get tricked!
