Discussion about the vector<bool> and its standards conformance.
Why is libc++'s vector<bool>::const_reference not bool?
by Howard Hinnant
From the article:
The motivation for this extension, which is detectable by a conforming program, and thus non-conforming, is to make vector<bool> behave more like vector<char> with respect to references (const and otherwise).

An unplanned 5th entry in my series on writing applications in C++ using Qt and boost:
A generic context menu class for Qt
by Jens Weller
From the article:
I didn't plan to write a second post on menus. But a reply on twitter caused me to over think my code I presented yesterday. Its not an very important part, so that I moved on once it did run. So, the simple question, why I would not connect the menus to a slot instead of using a switch was a good one. It would restructure the code, and slots are also callable from the outside world, while the switch buries the code inside a method...

Menus and Widgets in Qt
by Jens Weller
From the article:
Lets start with how Qt sees and handles menus. You can easily create a window menu in the RAD Editor of QtCreator, and then add a slot for its triggered() signal. But for a context menu...

Building factories in C++ with boost::factory
by Jens Weller
From the article:
boost has a small library focusing on the creation of factories as functional objects, so that boost::factory is part of boost::functional. The library offers...

Practical Type Erasure
by Cheinan Marks
Summary of the talk:
Type erasure looks like a neat concept, but what are its real life uses? This talk will briefly show the inner workings of type erasure, and demonstrate a real working implementation of a configuration system from public domain production code. Uses and pitfalls of type erasure will also be covered.

Polymorphism with Unions
by Jason Lucas
Summary of the talk:
Using tagged unions to create families of polymorphic types that are more flexible and more easily maintained than those formed with inheritance alone. We demonstrate the design pattern and implementation techniques of sum types with examples from a compiler development project. We also examine the technique's impact on project management and engineering and on algorithm design, including the role of type switches, value type semantics, and multiple dispatch polymorphism.

The first part in my series on writing applications with C++ using Qt and boost:
Trees, tree models and treeviews in Qt
by Jens Weller
From the article:
On Tuesday I've announced this new series, this is the first installment showing the progress. The first thing I did when I started to work on my new application, was to implement a generic tree class, that then is exposed through not so generic tree model to Qt. The QTreeView then simply displays the data in the tree. My goals are, that the class containing the tree it self, is independent from Qt. Yet as its used in Qt, there are a few design decisions which reflect the needs of the Qt Model View system...
