Haxl - A Big Hammer for Concurrency

Explore a groundbreaking approach to concurrency in programming through this conference talk from Strange Loop. Dive into the Haxl framework, developed and open-sourced by Facebook, which flips the default from sequential to concurrent programming. Discover how this paradigm shift can be beneficial and gain insights into its inner workings. Learn how the components enabling concurrency-by-default also enhance testing and debugging capabilities, making Haxl a powerful tool for addressing I/O and concurrency challenges. Follow along as Simon Marlow, a Software Engineer from Facebook's Abuse Detection Systems team, shares his expertise on topics including side effects, mock APIs, parallelism, and the motivations behind Haxl's creation. Gain valuable knowledge about this innovative framework that is being used to combat spam and malware at Facebook.
