Explore the world of WebAssembly from a unique, lower-level perspective in this 49-minute conference talk. Dive deep into the WebAssembly specification, going beyond the typical tutorials to understand its inner workings. Learn about the history of WebAssembly, its relationship to other technologies like the JVM, CLR, and Docker, and discover why it's becoming a popular choice for sandboxed, memory-safe runtime environments. Gain insights into LLVM, portable compilation targets, and various WebAssembly runtimes such as Wasmer and Wasmtime. Examine practical applications, including building web applications with Spin, and address topics like garbage collection and security in WebAssembly. Whether you're a web, backend, or systems developer, this talk offers valuable knowledge to enhance your understanding of this versatile technology.
