I understand Conway's Law as saying that any organization that designs or produces a product is destined/doomed to produce a product that is an image of their organizational structure. I originally though it was meant to be comedic, but have seen it play out a number of times in the projects I've worked in. When there are two developme...
I have a list of Parts and some of them need a pointer to an Engine, lets call them EngineParts. What I want is to find these EngineParts using RTTI and then give them the Engine. The problem is how to design the EnginePart. I have two options here, described below, and I don't know which one to choose. Option 1 is faster because it doe...
This is a pretty basic C++ design question: I have a class that contains some data which is read-only, once the object is constructed: class Foo { private: class Impl; Impl* impl_; public: int get(int i); // access internal data elements }; Now, I'd like to implement several ways to construct a Foo object and fill it with dat...

I'm trying to decide on a file extension for the saved files. My questions are: How important is it nowadays to stick to 3 characters? Where can you check how much this ...
My domain entities are lined up like a tree: Root - Child 1 -- Child 1.1 -- Child 1.2 - Child 2 -- Child 2.1 -- Child 2.2 We ended up with 2 (rather strong) opinions on how a repository should be designed around these domain objects: Opinion 1: I need 2 repositories Child1Repository & Child2Repository which gets managed by a RootFac...

For example, I'd like to be able to display different views based on the following route data: /{country}/ /{country}/{area} But in the same vein I'd like to di...
I wrote a class that wraps an iterator and returns transformed values on demand: // iterator-wrapper.h template<class Iter, class Val, class Fct> class IteratorWrapper { Iter cur_; const Iter last_; const Fct fct_; public: IteratorWrapper(Iter first, Iter last, const Fct fct) : cur_(first), last_(last), fct_(fct) {} con...

However, there's some logic in how the attributes are attributed: Operation Foo requires equipment A and B Operation Bar requires no equipment Operation Baz requires equipment B and either C or D Operation Quux requires equipment (...
I have come into the habit of hand-sketching various diagrams for software I create. My software is mostly for the web. I use E-R diagramming for the data logic (model of MVC) , and a personally invented diagram style for the interactions -- what pages lead to which other ones and what do they do, i.e. the views & controllers of MVC. Th...
