From Mathematics to Generic Programming: An Interview with Alexander Stepanov and Daniel Rose

 

John Lakos interviews Alexander Stepanov and Daniel Rose, authors of From Mathematics to Generic Programming, on their new book, why it applies to everyday programmers, and their positions on some closely related technical issues — including value semantics, concepts, contracts, and polymorphic memory resources — facing the C++ Standards Committee today.

Fighting off memory leaks and errors (C++11) -- Kacper Kołodziej

This article talks about how modern C++ idioms could be used to avoid memory leak and errors.

Fighting off memory leaks and errors (C++11)

by Kacper Kolodziej

From the article:

Modern tools provided with C++11's standard library make fight with memory leaks and errors easier and more effective. Sometimes problems which are seemingly not dangerous might put an end to your application. We are going to learn how to find and avoid them.

Counting bits -- Jens Weller

How to generate random bytes and how generic programming allow/support reuse code for different types.

   Counting bits

   by Jens Weller

From the article:

I did a bit of fun coding. I'm currently thinking on how to generate random bytes, for example the 16 random bytes for the initialization vector of AES. The mersenne twister RNG is known to give very good randomness, so it would be a possible an easy source. An std::array<uint32_t,4> would be a good container, filled with generate. But first, I wanted to know, how random is the mersenne twister really? So, when counting the bits in the result of a few thousand calls to a rng, the distribution should be even. So, today I wrote code that counts bits, and tested it on the mersenne twister.

Boost libraries are now supported in biicode

First step to a complete integration of the C++ deps manager biicode with the most popular set of C++ libs: Boost libraries.

Boost libraries are now supported in biicode

by Manu Sánchez

From the news:

At biicode we have been working hard to simplify the process of making Boost available for any C++ programmer with just an include. But this is only the start, the project has been released as open source to allow everyone contribute and help.

CppCon 2014 Make Simple Tasks Simple!--Bjarne Stroustrup

By Adrien Hamelin | Feb 20, 2015 08:00 AM | Tags: c++14 c++11 basics

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:

Elevate Your Code to Modern C++11 with Automated Tooling

by Bjarne Stroustrup

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

C++ faces two challenges: Helping programmers address the most demanding tasks in terms of performance, scale, and dependability. It must also help programmers be productive writing ordinary maintainable code. There is much more "ordinary code" than there is performance-critical code. Thus, C++ must make simple tasks simple while not getting in the way of tuning software for the last byte and last cycle where that's necessary. This talk focuses on what C++11 and C++14 offers to simplify programming: auto, range-for loops, move semantics, futures, concepts, and more. However, the focus is not primarily on language features: the key is programming: how can we write better, more readable, efficient, and more maintainable code? If you think that the essence of C++ is clever pointer manipulation and huge class hierarchies you may be in for a few surprises.

Common Algorithm Patterns -- Scott Prager

An interesting article concerning ranges, and how to make the ever useful algorithm header even more effective:

Common algorithm patterns

by Scott Prager

From the article:

Of the STL, <algorithm> may be the most well-used non-container library, but often requires a level of verbosity that requires just as much typing as the hand-written loop, making it not always feel so convenient. It benefits code that uses it with increased clarity and mathematical soundness, so reducing the syntactic overhead should be a goal of those using it. Today I will talk about these problems and demonstrate ways of making it more terse and sound.

CppCon 2014 Elevate Your Code to Modern C++11 with Automated Tooling--Peter Sommerlad

By Adrien Hamelin | Feb 18, 2015 08:00 AM | Tags: intermediate c++11

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:

Elevate Your Code to Modern C++11 with Automated Tooling

by Peter Sommerlad

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

This talk will motivate and demonstrate how to transform your existing C++ code into more modern style and better quality. A key to that is refactoring the code into better shape. While manual refactoring can be tedious and error prone the author demonstrates automated refactoring that was created by his students and assistants and himself over the last nine years on the basis of Eclipse CDT. The tooling works with all compilers, because it is independent of one.

For example, we will show how to eliminate unnecessary macros or replace them by type-safe C++11/14 alternative code automatically. Or, to replace pointers, plain arrays and manual memory management by references, smart pointers, std::string, std::array, or std::vector automatically. Also other transformations, such as introducing a template parameter to reduce a coupling to a single concrete type are demonstrated. All with the goal to modernize and hopefully simplify your C++ code. Even if you are not deeply interested in modernizing your code base, some helpful tooling, such as toggling function definitions into a single place, to change their signature, can be of great help. On the other hand, many of the proposed improvements can also be applied with your favorite code editor only more tediously.
