1 Table of Contents Preface The Express Handbook Conclusion 2 Preface The Express Handbook follows the 80/20 rule: learn in 20% of the time the 80% of a topic. In particular, the goal is to get get you up to speed quickly with Express. This book is written by Flavio. I publish programming tutorials on my blog flaviocopes.com and I organize a yearly bootcamp at bootcamp.dev. You can reach me me on Twitter @flaviocopes. Enjoy! 3 The Express Handbook 1. Introduction to Express 2. Installation 3. The first "Hello, World" example 4. Request parameters 5. Send a response to the client 5

std::simd how to express inherent parallelism efficiently via data-parallel types Dr. Matthias Kretz GSI Helmholtz Center for Heavy Ion Research CppCon ’23 @mkretz@floss.social github.com/mattkretzMotivation instructions/registers! consider SIMD an implementation-detail of data-parallelism We failed to express the “interesting” parallelism. Instead we expressed only 4 independent values and had to reduce to ResearchMotivation std::simd Overview Example: Image Processing Programming Models Outlook Summary How to express data-parallelism? Idea: Every pixel can be processed independently. ⇒ Process as many pixels in

options. Here is a non- comprehensive list of the ones I consider very relevant and worth learning: Express, one of the most simple yet powerful ways to create a web server. Its minimalist approach, unopinionated Vue and Angular. Can be used to create mobile apps as well. koa, built by the same team behind Express, aims to be even simpler and smaller, building on top of years of knowledge. The new project born developer experience with the least overhead and a powerful plugin architecture, inspired by Hapi and Express. 2. A brief history of Node.js Believe it or not, Node.js is only 13 years old. In comparison
