Using futures with callbacks.

Wrapping Callbacks with Futures

by Anthony Williams

From the article:

Libraries the perform time-consuming operations, or network-based operations, often provide a means of running the task asynchronously, so that your code can continue with other things while this operation is performed in the background...

Spy your memory usage with operator new

by Stefano Saraulli

From the article:

When we say "efficiency", we often think "time". The sooner the code does its job, the more it is efficient. What about memory? Granted, today even the lousiest laptop comes with “a bucket load” of RAM which...

C++ is a surprising language. Sometimes simple things are not that simple in practice. Last time I argued that in function bodies const should be used most of the time. But two cases were missed: when moving and when returning a value.

Does const influence move and RVO?

C++ is evolving.

Functional in C++11 and C++14: Dispatch Table and Generic Lambdas

by Rainer Grimm

From the article:

My favourite example the dispatch table shows how nice the features in modern C++ work together. A dispatch table is a table of pointers to functions. In my case, it is a table of handles to polymorphic function wrappers...
