CppCon Advice

Hello all, I've been programming in C++ for about 5 years now, 4 years in a university setting and 1 at my current employer. Recently, I put in a request to attend CppCon and it was accepted, which I'm thrilled about...

OOP Is Dead, Long Live Data-oriented Design

by Stoyan Nikolov

For decades C++ developers have built software around OOP concepts that ultimately failed us - we didn’t see the promises of code reuse, maintenance or simplicity fulfilled, and performance suffers significantly. 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 times faster because it ditches OOP for good in all performance-critical areas.

We will see how real-world C++ OOP systems can be re-designed in a C++ data-oriented way for better performance, scalability, maintainability and testability.

Concepts: The Future of Generic Programming (the future is here)

by Bjarne Stroustrup

Concepts have arrived. They will change the way we think about programming. Implementations are available in GCC and Clang. Many fundamental concepts are in the standard committee’s working paper and the next generation of the STL depends critically on concepts.

After briefly introducing concepts, I consider their role in design. What makes a good/useful concept? How do you design good concepts and use them well?

From a language-technical point of view, concepts are a way of constraining template arguments. From a design perspective, they are a focus comparable to user-defined types (classes): The intent is for a concept to represent a fundamental concept in an applications domain (hence the name “concept”).

I will mention technical issues recently resolved  or currently being resolved in the committee, but my primarily focus is not concepts as a language mechanism but as a support for the development of good software.

Lightning Talks and Lightning Challenge

by Phil Nash

Whilst many of the main conference talks go deep, Lightning Talks are, well, lighter. That doesn’t mean you won’t gain deep insights from some. Many, however, are humorous, entertaining – and often high-energy...
