STL Concepts and Ranges--Eric Niebler

Here is a video of Eric Niebler presenting a future C++:

STL Concepts and Ranges

by Eric Niebler

From the video:

With concepts and ranges coming, big changes are in store for the Standard Library and for the style of idiomatic C++. The effort to redefine the Standard Library is picking up pace. Come hear about one potential future from one of the key people driving the change. In this talk, Eric works through a tricky example and shows an elegant solution rooted both in yesterday's STL and tomorrow's. He will speak briefly about where we are in the process to reinvent and reinvigorate the Standard Library.

CppCon 2014 Boost.Asio and Boost.Serialization, Part II--Bryce Adelstein-Lelbach

By Adrien Hamelin | May 21, 2015 08:00 AM | Tags: boost

While we wait for CppCon 2015 in September, we’re featuring videos of some of the 100+ talks from CppCon 2014. Here is today’s feature:

Boost.Asio and Boost.Serialization, Part II

by Bryce Adelstein-Lelbach

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Network programming in C++ frequently requires programmers to find a way to express C++ objects as a sequence of bytes which can be transmitted and reconstructed on another network endpoint. In the case of simpler objects (such as most PODs), object serialization is trivial to perform.

For more complex C++ constructs (polymorphic objects, etc), the approach to serialization is more challenging. This talk will discuss how two powerful Boost libraries, Asio and Serialization, can be used to craft C++ networking code that can handle a vast array of uses cases. A prototype for a message passing framework will be developed throughout the talk.

Programmers familiar with or interested in network programming (but perhaps unfamiliar with Boost.Asio, Boost.Serialization or both) are the intended audience. No prior knowledge of Boost.Asio and Boost.Serialization will be assumed, and alternatives to both libraries will be discussed.

C++ Best Practices: A Forkable Standards Document - Jason Turner

By Jason Turner | May 19, 2015 12:11 AM | Tags: community

A forkable coding standards and best practices document for C++.

C++ Best Practices

by Jason Turner

From the book

It (C++ Best Practices) compliments books such as Effective C++ (Meyers) and C++ Coding Standards (Alexandrescu, Sutter). We fill in some of the lower level details that they don't discuss and provide specific stylistic recommendations while also discussing how to ensure overall code quality.

...

This document is based on my personal experiences. You are not supposed to agree with it 100%. It exists as a book on github so that you can fork it for your own uses or submit back proposed changes for everyone to share.

 

Using Monads in C++ to Solve Constraints: 3. The Tale of Two Monads—Bartosz Milewski

By Marco Arena | May 18, 2015 10:33 AM | Tags: intermediate

Bartosz Milewski continues to explain how to use Monads in C++.

Using Monads in C++ to Solve Constraints: 3. The Tale of Two Monads

by Bartosz Milewski

From the article:

The functional solution to our problem involves the combination of the list monad and the state monad. Mashing two monads together is not trivial — in Haskell this is done using monad transformers — but here I’ll show you how to do it manually...

CppCon 2014 Sanitize your C++ code--Kostya Serebryany

While we wait for CppCon 2015 in September, we’re featuring videos of some of the 100+ talks from CppCon 2014. Here is today’s feature:

Sanitize your C++ code

by Kostya Serebryany

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

"Sanitizers" is a family of dynamic testing tools built into C++ compilers (Clang and GCC):
AddressSanitizer finds memory errors, such as use-after-free, buffer overflows, and leaks;
ThreadSanitizer finds data races, deadlocks, and other threading bugs;
MemorySanitizer finds uses of uninitialized memory;
UndefinedBehaviorSanitizer finds other kinds of undefined behavior, such as use of incorrect dynamic type, shift by illegal amount and many others.
You will learn how these tools work, how to use them on small programs and how we deploy them in large projects.

CppCon 2014 Large-Scale Refactoring @ Google--Hyrum Wright

Large-Scale Refactoring @ Google

by Hyrum Wright

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Many organizations have significant investments in a large existing C++ codebase, and Google is no exception. Our code is intended to survive for decades, but continue to track new language standards as they emerge. To do so, we have developed tools and techniques which provide the ability to automatically refactor code to use new APIs as they become available.

In this talk, I'll discuss some of the reasons for doing migrations that impact hundreds of thousands of files, and how we do them at Google, using tools such as ClangMR. I'll give examples, such as our recent migration to the standardized std::unique_ptr and std::shared_ptr types and lessons we've learned from these experiences. Finally, I'll point out pitfalls others may face in doing similar work, and suggest ways that they can be avoided.

Handling short codes (part I)--Andrzej Krzemieński

By Marco Arena | May 15, 2015 06:02 AM | Tags: performance intermediate

First part of a discussion about designing a type storing character strings of length N (known at compile-time and sufficiently small).

Handling short codes - part I

by Andrzej Krzemieński

From the article:

In my work, we often deal with codes [...] The initial choice was to represent them in programs by type std::string, a general-purpose type for storing sequences of characters. But, as with any general-purpose tools, they fail to take into account the particular usage cases which often offer room for improvements [...] The following is an attempt at the design of a type that would take advantage of the information that we are only storing character strings of length N, where N is sufficiently small (say, no longer than 8)...

Using Monads in C++ to Solve Constraints: 2. The State Monad

by Bartosz Milewski

From the article:

We all like making plans, but they are often contingent on the state of our finances. Such plans can be described by functions. In general, a financial plan is a function that takes cash and returns the result paired with the new value of cash. It can be described generically using a template...
