CppCon 2016: John Lakos “Advanced Levelization Techniques (part 1 of 3)'

—

Developing a large-scale software system in C++ requires more than just a sound understanding of the logical design issues covered in most books on C++ programming. To be successful, one also needs a grasp of physical design concepts that, while closely tied to the technical aspects of development, include a dimension with which even expert software developers may have little or no experience. In this talk we begin by briefly reviewing the basics of physical design. We then present a variety of levelization and Insulation techniques, and apply them in present-day, real-word examples to avoid cyclic, excessive, or otherwise inappropriate dependencies. Along the way, we comment on how to make the best use of what the C++ language has to offer.

So much goodness herein. I honestly think collectively we owe John at the very least a tip of the hat. He’s applied so much effort to the domain of software engineering at scale.

[thongphamvan]

Great talk! This is what am I looking for.

[origamibulldoser]

In the example of Logical Relationships; wouldn't simply declaring and defining the PointList_Link in the .cpp file be enough to ensure it isn't used outside of PointList?

[TheIronSavior]

12:00 He made a joke about how the people he normally works with are "slower" than this audience. I bet they're feeling the love.

[thongphamvan]

Does anyone know the tool he used to extract the dependencies between components? Is it open source?

[lapinrigolo]

Does anyone know if that tool is open source?

Cycle = failure to abide by causality.
