Some Internet Links related to Clean Code

Two YouTube-Videos "Pro & Contra Clean Code:

• https://www.youtube.com/watch?v=tD5NrevFtbU
  "Clean" Code, Horrible Performance
  covers C++ but looks exclusively at performance conseqiences of "clean code"
  not at other impromements like readability, testability, modularity ...
• https://www.youtube.com/watch?v=zVLuQAnNue8
  Is Clean Code Really That Bad For Performance
  covers C# and looks at how an optimizing compiler can revert things
  which technically would make a "clean code" solutions less performant

A video by Scott Meyers which (among other things) covers C++ "perfect forwarding"

• https://www.youtube.com/watch?v=IqVZG6jWXvs
  `std::move` doesn't move and `std::forward` doesn't forward

A video by Sean Parenr why to prefer algorithms over explicit logic and nestet loops:

• https://youtu.be/W2tWOdzgXHA?t=529

A section of the C++-FAQ detailing the criteria when (and when not) "Inheritance"  is appropriate

• https://isocpp.org/wiki/faq/proper-inheritance

Books by Plauger and de Marco (Oldies but Goodies):

• "Programming on Purpose" (3 Books, one on "People" = Human Resources)
• "Peopleware" (dt. "Wien wartet auf Dich") mit kürzeren Essays
  und "The Deadline" (dt. "Das Projekt") ein vollständiger Romen

Selected Info-Graphics (from https://tbfe.de/data/uploads/infographics)

• Example-OpenClosePrinciple (GoF "Template Methode Pattern")
  classical solution with virtual member functions vs.
  kind of "policy-based" solution with C++ templates

More Examples with the Compiler-Explorer:

• Optimize Beispiel 1
• Optimize Beispiel 2
• `typeid`, `boost::type_index` und Makro-Techniken
• Copy/Move delete/default
• FCOI Alternative 1 (central class extended with interfaces)
• FOCI Alternative 2 (multiple inheritance with overlapping base class)
• FCOI Alternativen 1 und 2 ("side by side" comparison of the above)
