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...

The fourth part of my series about developing applications with C++ using Qt and boost:
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...

The 3rd entry in my series about building applications with C++ using Qt and Boost:
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...

Do you know how the uniform initialization?
Bitesize Modern C++: Uniform initialization
by Glennan Carnie
From the article:
C++98 has a frustratingly large number of ways of initialising an object.
(Note: not all these initialisations may be valid at the same time, or at all. We’re interested in the syntax here, not the semantics of the class X)
One of the design goals in C++11 was uniform initialisation syntax...

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...

I'm starting a series on my blog and youtube channel, about building an application in C++:
Building Applications with Qt and boost
by Jens Weller
From the article:
This is the start of a series of posts, in which I'll try to document my weekly work on a new application, build with Qt and boost. This first post is rather short, but I'd quickly try to give you an overview, why I use both Qt and boost in the same application. Regarding Qt, I wrote an introduction a two years ago, also for boost, there is an excellent website/tutorial about boost by Boris Schäling (buy his book!
). This series is not meant as a general introduction, yet I try to show you how and what I use of Qt and boost.
