Newer Isn’t Always Better: Investigating C++ Legacy Design Trends and Their Modern Replacements - Katherine Rocha - CppCon 2024
---
All code is legacy code, or so they say. Software engineers scoff at the idea of new code instantly becoming legacy code, however software is a time capsule holding the design trends of the time the code was written. As new code is written, new design trends are used and potentially overused, just like the legacy patterns. What if these new design trends have more in common with the original design trends than we initially thought. One example we will investigate is object oriented design through polymorphism and how it has been replaced in many cases with template metaprogramming. There are a variety of template metaprogramming strategies that achieve the object oriented design principles, however when overused you can encounter as many templates as there would be virtual functions in object oriented programming. Have we discovered that balance is the solution or are we still overusing the “fancy” new thing? In this talk, we will investigate various legacy design trends including further examining object oriented design, the singleton pattern, as well as other legacy anti-patterns to reveal the updated trends. We will address each legacy anti-pattern and their corresponding modern update to evaluate whether newer is better or if we have recreated the same legacy problem.

CppCon is the annual, week-long face-to-face gathering for the entire C++ community. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in Aurora, Colorado, near the Denver airport, and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.
