Yesterday on SO:
A positive lambda: +[]{} -- What sorcery is this?
Does anyone know why this
#include <functional> int main() { auto test = +[]{}; // note the unary operator + before the lambda test = []{}; }works? It compiles fine with both GCC 4.7+ and Clang 3.2+. Is the code standard conforming?

The second part of my series about the papers for Chicago:
Papers for Chicago: Core, Concepts and Evolution
by Jens Weller
From the article:
This time I cover core, concepts, evolution and filesystem. I decided to keep the format with grouping the papers by domain, it makes it easier to have an overview.

Do you know what value-initialization means, and why it's simpler in C++11?
Value-initialization with C++
by Andrzej Krzemieński
From the article:
Some time ago, I showed how
boost::value_initializedcan be used to value-initialize objects in generic components in C++03. In C++11 it is practically not necessary. C++11 gives you a way to force value-initialization of your objects in any possible initialization context.Are you familiar with term “value initialization”? It is sometimes confused with “default-initialization”...

The first piece of code acquired by the Smithsonian's Cooper-Hewitt National Design Museum -- "Planetary", written in C++.
Planetary: collecting and preserving code as a living object
Posted by Sebastian Chan & Aaron Cope on Monday August 26, 2013
From the article:
Cooper-Hewitt has just acquired its first piece of code. Although the collection has objects that are the end result of algorithmic processes, notably Patrick Jouin's 3D printed chair, Solid C2, this is the first time that code, itself, has been collected.
Almost all contemporary design practice involves digital processes -- from the ubiquitous Adobe design software to CAD packages used by product designers and architects, to the simple day-to-day office management and accounting software -- it would be difficult to find a designer who lives entirely 'off the grid.’ Despite this, design museums have been slow to start to add software to their permanent collections.
Some of this reticence to collect digital objects stems from deep uncertainties as to how to preserve and present such objects to future visitors and future scholars. But for Cooper-Hewitt these uncertainties have been a strong driver to experiment.
So, here we have Planetary.
Planetary is an iPad application written in C++ using the Cinder framework. Planetary offers an alternative music player application for the iPad that visualizes your music collection as a series of celestial bodies. Songs are moons, albums are planets, artists are suns—and the orbits of each are determined by the length of albums and tracks. Their brightness represents their frequency of playback.

Tales of C++, Episode 6:
Boollocks
by K-Ballo
From the article:
In the beginning there was no
bool. And C++ said "let there bebool", and there wasbool...The Boolean data type is an integral type with only two values:
trueandfalse, intended to represent the truth values of logic and Boolean algebra. With only two values, what can possibly go wrong?

Continuing Koenig's series on move semantics:
Addresses and Nodes: Two Ways To Get Around
by Andrew Koenig
From the article:
Programs that avoid address arithmetic can also avoid moving data. The reason is that it is only arithmetic that really cares about where in memory an object is; in other circumstances, having a pointer to that memory is enough.
