The feature set for the C++17 release is set, and the release of the standard is just around the corner. In this session, we'll discuss all the new C++ features in C++17 and…

C++ solves the problem of runtime polymorphism in a very specific way. It does so through inheritance, by having all classes that will be used polymorphically inherit from the same base class,…

The proposed range concepts for the standard library are a significant improvement but are designed for the mental model of iterating and mapping values, not hierarchical domain decomposition. Even…

Undefined behavior (UB) is one of the features of C++ that is both loved and hated. Every C++ developer cares about performance, which is why it is very important to understand what…

Technical debt is the bane of most established libraries, whether it is standard library or boost or local library developed in house. Paying this debt is expensive and in many cases seems infeasible.…

The most significant improvement in C++17 will be Parallel Algorithms in the STL. But it is meant only for CPUs, as C++ does not define heterogeneous devices yet (though SG14 is…

For the past several years, I have been researching new languages to support safe and efficient network protocol processing, specifically for software-defined networking applications. The unfortunate…

If you were to ask a C++ developer the question "what is execution?" you may get a different answer depending on who you asked. This is because execution means something different to…

Exceptions are often described as 'slow', and the standard advice is to use them only in exceptional circumstances. In this talk, we'll find out how slow exceptions really are by exploring the Itanium…

Memory allocators have a bad rap. Sure, they give us control, sometimes vital control, over how and where memory is allocated, but they seem so hard to use correctly. The allocator model that was…

Developing consistent and meaningful benchmark results for code is a complex task. Measurement tools exist (Intel® VTune™ Amplifier, SmartBear AQTime, Valgrind, etc.) external to applications, but…

No offense to Shakespeare, but in C++ there is a lot in a type name. A name represents a set of data and behaviors, and changing names is an often difficult and painful process. This could be…

Facebook has developed tooling to help quickly find and debug several classes of concurrency bugs in Facebook's large C++ codebase. In this talk, we will focus specifically on deadlocks and…

Most C++ developers know that using globals (or singletons) excessively in code is usually a poor decision. But it is also hard to deny their usefulness in more than one situation: for…

Higher-order functions are functions that take other functions as arguments. This is very frequently used in functional languages, somewhat less so in C++, although this is slowly changing…

Spacecraft travel our solar system with exquisite accuracy. It is almost commonplace to learn that a spacecraft hit bullseye to within a few seconds after over a decade of space travel. How do we do…

Programming your application with Qt means that you will sooner or later encounter the central QObject class, signal & slot connections, or generic properties. The object model makes it safe and…

This talk will present the uftrace function graph tracing tool, which was first introduced at CppCon last year. The uftrace tool utilizes function instrumentation techniques from compilers to provide…

At Facebook, the main bottlenecks in build times are caused by auto-generated code from our core RPC Framework. Through the use of templates we were able to obtain up to 50% build speedup in our…

C++ has a handful of associative containers. We started with set and map, both based on node-based red-black trees. These are fine but are not the most efficient and, in particular, suffer…

When writing a C++ program, we tend to think of the strengths and weaknesses of our computer, just as we think of our algorithms, data structures, and probably of language features we want to…

Compile-time constraints will likely soon become part of our routine C++ programming vocabulary. Why? Such constraints are induced by new core language features (requires-clauses and…

You can run C++ on any computer you want, as long as it pretends it is an 80’s computer. Conveniently most computers pretend to be 80’s computers – with extras, but nothing too radical –…
