Data-oriented design can be a better paradigm in fields where C is most important - game development, high-performance computing, and real-time systems. The talk will briefly introduce data-oriented design and focus on practical real-world examples of applying DoD where previously OOP constructs were widely employed. Examples will be shown from modern web browsers. They are overwhelmingly written in C with OOP - that’s why most of them are slow memory hogs. In the talk I’ll draw parallels between the design of systems in Chrome and their counterparts in the HTML renderer Hummingbird. As we’ll see, Hummingbird is multiple time
