Hanno Embregts is a Java Developer with a passion for learning, teaching and making music.In his day-to-day job as an IT Consultant at Info Support, Hanno prefers work that is fast-paced and versatile. This is why he juggles Java development, software architecture, public speaking, leading Info Support’s Java Community and teaching courses at Info Support’s Knowledge Centre. He is also one of the editors of the Dutch Java Magazine. Outside of work Hanno likes making music with his friends. He plays the flute, the guitar and he likes to sing.Software conferences are Hanno’s favourite thing in the world, because they allow him to do the three things he loves most at the same time: learning new things, teaching others about stuff he discovered and yes: even making music from time to time!
Will Git Be Around Forever? A List of Possible Successors
Tools-in-Action (INTERMEDIATE level)
Room 2

Ten years ago, only Linux kernel committers and other early adopters used Git. Almost everyone else used Subversion. Ten years later, Git is the most popular product. Which makes me wonder: what will we use another ten years from now? And what features would YOU want from your version control software in 2033? No history rewrites? Faster? No merge conflicts ever?

In this talk I'll discuss a few post-Git products, including Fossil, Pijul and Sapling, and their support for the features we so dearly desire. I'll also try to predict which one will be 'the top dog' in 2033.

So attend this session if you're excited about the future of version control and if you want to have a shot at beating even (!) the early adopters. Now if it turns out I was right, remember that you heard it here first. 😀


In the summer of 2021, I got my Java 11 certification. I expected it to be a breeze, because I’d been a Java developer for 14 years already and surely I should have seen it all by now. Boy, was I wrong! I came across lots of things that I didn't even know were possible with Java.

Now this can either mean that I have been a terrible developer for a painfully long time, or that these things are just a bit lesser known and in fact very interesting to hear about.

I'm hoping the latter is actually the case, so in this talk I will take 15 minutes to go through 11 things that took me 14 years to learn. Which means that you have the chance to learn these things 490896 times faster than I did! 🚀


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!
