More About Adopting Scripting Languages
In last week’s post I wrote about adding a scripting language to our toolset. I focused on the benefits a scripting language like e.g. Python can bring, especially when it […]

Scripting Languages and C++
C++ programmers often praise their statically typed language. Having a compilation phase with the possibility to statically check for possible errors is a feature that makes good for the time […]
Do Domain Specific Languages add Complexity to Plain C++?
C++ itself is complex enough. Adding domain specific languages can seem like yet another addition to that complexity. So why would we use a DSL instead of a normal library?
Use a static analyzer or two
In the last two posts I have written about compiler warnings. There’s much more to getting hints about code smells and potentially problematic pieces of code than that. That’s the job […]
Compiler Warnings Part 2 – Tune the Compiler
In the last post I wrote about how to change our code to avoid getting compiler warnings. Sometimes that is not a feasible approach and we need to tell your compiler […]
Compiler Warnings Part 1 – Treat Them Right
We often see compiler warnings about pieces of code that have potential problems or poor style. Sometimes they point out code that is actually wrong, so don’t ignore them.
Modern C++ features – in-place construction
Move constructors are often cheaper than copy constructors, which makes the construction and immediate relocation of objects in modern C++ more effective than in C++03. However, just moving the parts needed to construct the object in the right place can be even more effective. Several standard library functionalities use perfect forwarding to construct objects right where they are needed.
Get rid of those cheat sheets!
This is another post motivated by Twitter: It’s about those cheat sheets, for example those showing C++ operator precedence, that some people have stick to their monitor or cubicle wall. Unless they […]
Constructor Failures
Sometimes we fail to acquire a needed resource or responsibility during the construction of an object. Sometimes the construction of a subobject fails. How can we deal with an incompletely […]
Avoid Invalid State
Have you seen classes with a method isValid() or something similar? You most definitely have seen and even used such classes. Maybe you have even written such a method yourself. […]
