GraphQL is a solid way of building responsive web and mobile APIs. It's not always obvious, however, how to structure your APIs. When should you use a transformer? When are GraphQL subscriptions appropriate? In this tech talk, we'll go through the principles of building robust APIs powered by GraphQL for a range of interesting use cases. Learning Objectives: – Learn about the main principles that define robust GraphQL APIs – Learn about the building blocks that are available and when to use them – See how AWS Amplify and AWS AppSync make it easy to run your GraphQL backend SPEAKER: Nader Dabit PUBLICATION PERMISSIONS: The speaker provided Coding Tech with the publication permissions. https://www.youtube.com/watch?v=-cCbTcNyk-Y

oday, almost every computer, tablet and phone comes with audio input and output. Computer games and many other kinds of applications would be unthinkable without sound. Yet, the C++ language has no notion of it. Literature on audio in C++ is sparse. For even the simplest possible audio functionality, programmers need to deal with a confusing landscape of complex platform-specific APIs and proprietary 3rd party libraries. But audio in C++ doesn't have to be hard! First, we show how audio signals can be digitally represented in C++, covering basic concepts such as channels, audio buffers, PCM, and sample rate. We explain the principles of communicating with your soundcard and playing, recording, reading and writing audio data. In the second half of the talk, we will discuss a proposal to add a minimal, modern audio API to the C++ standard library. We will show the basic design, the current state of the implementation, and simple example apps. We finish with an update on the current state of this proposal.
