A cookiecutter-based project template to easily create cross-platform C++ library projects.

Among its features:
* Android and iOS sample apps that integrate the cross-platform library stencil.
* Unit test integration via Catch/2 with a canary test built-in.
* Lint style checking via Cppcheck.
* API documentation generation via Doxygen.

A longtime needed iterator for C++ STL std::bitset<N>.

An STL std::bitset could be seen as a set of integers. For example, consider an instance of std::bitset<8> like 0b01001011. Such instance can be seen as the set of integers { 0, 1, 3, 6 } corresponding to all its set bits. Yet, why not, it could be also seen as the set of integers { 2, 4, 5, 7 }; these are the indices of all unset bits.

Using std::bitset to model a set of integers could be a matter of convenience given its compact runtime footprint. Also, the ability to load it from, unload it to an unsigned number.

Unfortunately, for those scenarios where std::bitset is a smart choice to represent sets of integers, the type provides no iterators. There's no convenience way to retrieve just the bits that are on (or, conversely, the ones off) other than just visit all bits and test their statuses.

Smartphones and tablets made personal computing more personal than ever. This post-PC era, with its new platforms and technologies, disrupted how developers design, build and deliver software. Moreover the fact the traditional PC renewal / replacement cycle is now longer confirms the notion that attention has shifted to the new form factors.

What role do C++ and C++ developers play in this new scenario?

Smartphones and tablets made personal computing more personal than ever. This post-PC era, with its new platforms and technologies, disrupted how developers design, build and deliver software. Moreover the fact the traditional PC renewal / replacement cycle is now longer confirms the notion that attention has shifted to the new form factors.

What role do C++ and C++ developers play in this new scenario?

In this talk, Diego reviews aspects that make C++ unique for ARM-based development, together with the many challenges and overlooked costs that C++ developers face when jumping in. Diego shows how the leading platforms enable C++ through technologies and tools. He also discusses the state-of-the art in cross-platform approaches with their pros and cons.

You'll leave this talk with a panorama of the many ways to use C++ in the post-PC world, what's already achieved and what still needs to be done. Show less

This is a column I wrote during 2012 and 2013, to divulge the evolution of C++ in its version C++11, aimed for Java and .NET developers who are looking to incorporate unmanaged code to their projects, given the uncontested performance benefits that native code delivers.

Diego Dagum discusses how to port C++ desktop applications to the Windows Runtime Library, using a sample calculator application as a practical example.

Mission-critical applications are vital for the normal flow of operations in any organization. This range of applications is characterized by a series of attributes, such as scalability, fault-tolerance, resiliency, and performance. While it’s pretty easy to get any of these attributes in isolation, meeting all them together is not a straightforward process. It typically happens that, when applying techniques intended to maximize—let’s say—scalability, performance might be eroded; performance… Show more

Mission-critical applications are vital for the normal flow of operations in any organization. This range of applications is characterized by a series of attributes, such as scalability, fault-tolerance, resiliency, and performance. While it’s pretty easy to get any of these attributes in isolation, meeting all them together is not a straightforward process. It typically happens that, when applying techniques intended to maximize—let’s say—scalability, performance might be eroded; performance enhancement may cut graceful degradation capabilities, and so forth. This session explores all those tradeoffs, offering effective guidance to deal with mission-critical attributes altogether. After attending this session, the attendee will be able to identify those friction points, applying integral techniques in order to maximize the fulfillment of those attributes at once. This session also offers health checking techniques for diagnostics, to guarantee that quality-of-service agreements are being fulfilled. Show less
