Large Scale C++ with Modules: What You Should Know

by Gabriel Dos Reis

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

“Modules” are a frequently requested and long-awaited feature by C++ programmers. In a nutshell, the idea is to have a direct language support for (a) expressing the boundaries and dependencies of a program component; (b) isolating source codes from macro vagaries; (c) scaling compile time, especially for large projects, given the ubiquity of “headers-only” template libraries; (d) spur innovation and deployment of semantics-aware developer tools.

This presentation will focus on three major points: (1) the design of the module proposal currently being considered by the C++ standards committee (design goals, properties, constraints); (2) implementations currently under way; and (3) early user experience and migration.

Modules directly address a problem (scalability) listed as one of the three major areas where C++17 is expected to significantly improve daily experience of the working C++ programmer. Naturally, this feature is also on the top ten list of C++17 functionalities Bjarne Stroustrup put forward in his “Thought on C++17.”

Episode 63 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Alfred Bratterud, CEO of IncludeOS to discuss Microservice applications with the IncludeOS platform.

CppCast Episode 63: IncludeOS with Alfred Bratterud

by Rob Irving and Jason Turner

About the interviewee:

Alfred has been doing research towards IncludeOS since 2013, and got a PhD scholarship based on the early work in 2014. The IEEE CloudCom paper introducing the IncludeOS prototype was published in 2015 and he spun out a startup around IncludeOS in 2016, in collaboration with Oslo and Akershus university college (the largest institution for engineering education in Norway). He's currently focusing 100% on developing IncludeOS from research experiment to a production ready platform for cloud services.

Alfred holds BSc and MSc in computer science, with focus on logic and computability, from the university of Oslo. He has 10+ years of industrial programming experience, mostly in web services. He's been working at Oslo university college since 2011, teaching various subjects ranging from operating systems, sysadmin and firewalls to web development. He started learning C++ when he took over a C++ course at the college in 2011. A very good year to start C++.

CppCon 2015 Organizational Leadership with Modern C++--Kevin Kostrzewa & Johm Wyman

Organizational Leadership with Modern C++

by Kevin Kostrzewa & Johm Wyman

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

With the "C++ Renaissance" it is imperative that the technical leadership prove their mettle to lead a large organization into adopting modern practices and idioms.

In this talk, John and Kevin will discuss various techniques that they have employed to help drive their large development organization (~ 75 software engineers) towards a culture of modernization - some techniques that have worked well, and some that have not.

This will not be a discussion on specifics and nuances of the language. This is more a "fuzzy" discussion on what it means to be both at the forefront of the language and a leader / champion for your peers.

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.

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.
