Non Static Data Members Initialization
by Bartlomiej Filipek
From the article:
My short summary for non static data members initialization from modern C++. A very useful feature. Should we use it or not?

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:
Using C++ on Mission and Safety Critical Platforms
by Bill Emshoff
Summary of the talk:
The Joint Strike Fighter (JSF) is the first major DOD aircraft program to use C++. Much of this software is either safety critical or mission critical and so must be written in such a way as to be clear, readable, unambiguous, testable, and maintainable. We discuss the driving requirements behind the standard and its evolution. We give a quick overview of our standard and discuss how it differs from later standards such as MISRA C++. We discuss lessons learned over our nine year history of applying the standard to a large embedded software program. We also address ambiguities in rules and difficulties with automated checking of conformance with the standard.

Almost every C++ application and game deals with entity management.
Video Tutorial -- Handle-based entity management
By Vittorio Romeo
From the tutorial:
Entities are usually self-contained objects that...
- ...store data and/or logic.
- ...are tied a specific concept (e.g. an UI widget, or a 3D model).
- ...we need to keep track of.
- ...can either be alive or dead.
- ...are extremely often used in groups.
Problem: we need to keep track of specific entity instances, and iterate on every instance. We also need to remove dead entities and add new entities.
Keeping track of specific instances is easily solved with pointers and smart pointers.
Fast-iteration of a group of objects with the same type is achieved with cache-friendly memory locality and no indirection.
Adding and removing entities stored in a cache-friendly manner invalidates existing pointers.How can we facilitate instance tracking/addition/removal and still allow fast iteration?
In this video, we will create a generic container that stores objects in a cache-friendly way, allows to keep track of specific object instances and also allows addition and removal of entities.

Published on InformIT in which John Lakos interviews Alexander Stepanov and Daniel Rose about various aspects of generic programming and modern C++.
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.

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.

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

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.

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
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.

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.
