completion T : Improving the future T with monads

by Travis Gockel

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

std::future provides us a mechanism for asynchronous communication between a provider and receiver. However, the C++14 standard does not allow for actual asynchronous programming, as the only ways to interact with an std::future are blocking calls. The proposed then helps, but the interface is awkward and can be extremely slow when handling exceptions. Here, I will talk about completion a high-performance, async-only and monadic alternative to std::future and how it is used at SolidFire.

Functional Design Explained

by David Sankel

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

An oft-cited benefit of learning a functional language is that it changes one's approach to solving problems for the better. The functional approach has such a strict emphasis on simplistic and highly composable solutions that an otherwise varied landscape of solution possibilities narrows down to only a few novel options.

This talk introduces functional design and showcases its application to several real-world problems. It will briefly cover denotational semantics and several math-based programming abstractions. Finally, the talk will conclude with a comparison of functional solutions to the results more traditional design methodologies.

No prior knowledge of functional programming or functional programming languages is required for this talk. All the examples make use of the C++ programming language.

Simple, Extensible Pattern Matching in C++14

by John R. Bandela

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Recently, there has been in increased interest in applying functional programming techniques to C++. A very convenient construct that is used in functional programming languages is pattern matching. Due to the features introduced in C++11 and C++14 we can actually write a simple, easy to use, understandable, and extensible pattern matching library that is header only and uses no macros.

In this talks we will discuss the motivations for pattern matching, and see examples of use from other languages. We will then go on to design and implement a pattern matching library in C++. Particular attention will be payed to new C++14 features that greatly simplify the implementation such as integer_sequence, function return type deduction, and generic lambdas. The implementation will also serve a practical guide to using variadic templates and std::tuple.

We will show how the library can be easily extended and customized by working through some examples of customization such as working with user defined classes and structs, pointers, tuples, boost::optional, and boost::variant. At the end of the session, the audience will have an appreciation for pattern matching, as well as a sense that the C++11/14 features open new paradigms without sacrificing understandable code.

CppCast Episode 62: C++ and Lua Game Development with Elias Daler

by Rob Irving and Jason Turner

About the interviewee:

Elias Daler is a CS student, indie game developer, and C++ enthusiast. Passion for game development was the starting point for learning C++ and he's been programming in it for 6 years. Elias is working on a game called Re:creation and various open source C++ libraries. He also writes various articles about game development, C++ and Lua/C++ integration at eliasdaler.wordpress.com. These articles are well received and frequently shared on various game development subreddits and forums.

Time Programming Fundamentals

by Greg Miller

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

"Time zones are logical and easy to use." -- No one ever

Time programming is notoriously difficult and error prone. Attempts at handling daylight-saving time, for example, often yield baffling code, which of course is explained by a similarly misguided comment. Programmer confusion can spread virally throughout the codebase when these misconceptions find their way into library interfaces.

The problem is not that dates and times are fundamentally complicated (though they are). The problem is the lack of a simplified mental model with library support. This would give programmers the concepts and vocabulary necessary to reason about and discuss these concepts, and the ability to express this reasoning in simple C++ terms.

In this talk I will show how date and time programming evolved into what it is today. I will present a greatly simplified mental model that applies to all programming languages. I will show clear examples using an open source C++ library that implements these simplified concepts. And I will present practical tips for proper time hygiene that should be used by everyone immediately.

CppCon 2015 functional: What's New, And Proper Usage--Stephan T. Lavavej

functional: What's New, And Proper Usage

by Stephan T. Lavavej

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

functional gained lots of machinery in C++11, with further changes in C++14 and C++17. This talk will cover what's new in 11/14/17, focusing on how to use it properly. For example, you've probably used std::function, but do you know the criteria for activating the Small Functor Optimization? (It's not just being small!) We'll also look at bind(), mem_fn(), C++17's invoke(), and more.
