### Martina Krays:WebAssembly: Embedded native Code inside the Webbrowser – C++ goes Web ###

Porting an old C++ Desktop App to a Single Page Application without rewriting business logic?
That's possible with web assembly. Further running native embedded Code inside the browser comes without a performance penalty. This enables the developer to create also compute heavy tasks like video and image rendering. After small examples, aiming to show the compiler toolchain, Martina will deep dive into the question: How to port existing C++ Application to web assembly?

Bio:

### Ruben Bridgewater: Error handling: doing it right ###

It’s weekend and you are out at a lake with your family. You get a call from your boss that the application is down and the customers complain all over. You hurry home to fix the issue right away but you can’t find it and decide to revert to the last working state. Later you spend half your sprint searching and fixing the problem.

We all have run into issues like this before and our logs did not provide enough information to figure out what the problem is about. You saw a lot of errors but some had no stack trace and if they did, they were often useless because of the asynchronous JS nature hiding the actual call site.

But why all this pain when our life could be peaceful by using best practices in error handling? This is a journey into the asynchronous debugging horrors and the simplicity that async / await in combination with error classes can bring into that world

Bio:
Ruben Bridgewater is a Node.js collaborator and a software architect consultant. His main emphasis is building powerful and easy to use APIs for scalable and fast applications.
