Modern C++ Features – nullptr
Probably everybody who has written C++03 code had the pleasure of using NULL and stumbling over one pitfall or another. C++11 brought the solution to those issues with nullptr.
Modern C++ Features – override and final
Today I write about override and final, a pair of less often discussed, less complicated features introduced in C++11. Both can provide some additional security and clarity when it comes to […]
shared_ptr Versus unique_ptr in Factory Functions

Lambdas Part 2: Capture Lists and Stateful Closures
In the last post of my series about (relatively) new C++ features I introduced lambda expressions, which define and create function objects on the fly. I left a few details untouched, […]
Modern C++ features – lambdas
Having covered the basics of `auto` and rvalue references, there is a third big new C++ feature definitely worth knowing about: creating function objects on the fly with lambda expressions.
Testing as a Developer
One of the more recent posts in my employer’s company blog is titled ‘What’s wrong with: “I don’t write any tests since I am not a tester”?’ – which made me think about the relation of developers to testing, and about the self-image of any developer who would say that sentence in earnest.
