| Description | J-Fall is the biggest Java conference of the Netherlands and is organized by and for the NLJUG, the Dutch Java User Group. Speakers from Info Support:
Using Transport Layer Security (TLS) the right way is often a big hurdle for developers. We prefer to have that one colleague perform “something with certificates”, because he/she knows how that works. But what if “that one colleague” is enjoying vacation and something goes wrong with the certificates? In this session we’ll take a close look at secure communication at the transport level. Starting with what exactly SSL or TLS is, we’ll dive into public/private keys, and signing. We’ll also learn what all this has to do with an unfortunate Dutch notary. Of course, there’ll be plenty of practical tips & trics, as well as demo’s. Attend this session to become “that one colleague”! A PhD in math is not required; experience with assembling furniture can come in handy.
Besides being useful, comments in source code can also be fun! This legendary StackOverflow post [1] tells me that sometimes a well-chosen joke put into source code can lighten the mood at work and make your developer life just a bit better. Now, because I am both a developer and a musician, I tend to use song lyrics to lighten up my code. So in this Ignite talk, I’ll demonstrate this by showing a few typical code fragments that could use some musical quality. And of course I’ll perform bits of the songs that go with it. So are you in for a light-hearted talk on code comments – slash – a mini-concert featuring songs by Coldplay, Oasis, Adam Lambert, Imagine Dragons and many more? Please join in and feel free to sing along!
In recent years there have been some large developments in web technology. The introduction of HTTP/2 in 2015 has given new life to Server Sent Events as Reactive Streams. To explore these technologies with you, I have made an application that turns the audience into an orchestra using Reactive Streams. In the talk we will look at how and why HTTP/2 came to be. I will show you what you need to do to make use of HTTP/2. I will give you practical guidelines to help you choose between Reactive Streams and Websockets. I will explain the core concepts behind Reactive Streams. When we have the concepts down I will show you how to use Reactive Streams with the Java 9 API’s and Spring Reactor. Finally we will see just how “Reactive” Reactive Streams truly are in a live demo. Bring your cellphones so you can participate in the Impromptu Orchestra! My talk will have been a success when at the end of my talk: . You understand why we have HTTP/2, what the main features are and how we can use them in practice. . You have gained a better understanding of what Reactive Streams are, when to use them and how they work. . You have experienced the real-timeness of Reactive Streams in a live situation. | |||
