The "diamond problem" (sometimes referred to as the "Deadly Diamond of Death" [6]) is an ambiguity that arises when two classes B and C inherit from A, and class D inherits from both B and C. If there is a method in A that B and C have overridden , and D does not override it, then which version of the method does D inherit: that of B, or that of C?
Valentina is an open source pattern drafting software tool, designed to be the foundation of a new stack of open source tools to remake the garment industry. [5] The program was named after mother of the founder Roman Telezhinsky, a cutter by profession, who gave him the idea for the project.
He has started up several of the conferences in the Pattern Languages of Programs (PLoP) conference series and is a longstanding pattern author and PLoP shepherd. His pattern form, the "Coplien Form," [ 2 ] is a simplified way to structure a pattern in preparation for writing a more literate version in Alexandrian form.
The curiously recurring template pattern (CRTP) is an idiom, originally in C++, in which a class X derives from a class template instantiation using X itself as a template argument. [1] More generally it is known as F-bound polymorphism , and it is a form of F -bounded quantification .

The Rosetta Code site is organized as a browsable cross-section of tasks (specific programming problems or considerations) and computer programming languages. [2] A task's page displays visitor-contributed solutions in various computer languages, allowing a viewer to compare each language's approach to the task's stated problem.
The bridge pattern is a design pattern used in software engineering that is meant to "decouple an abstraction from its implementation so that the two can vary independently", introduced by the Gang of Four. [1] The bridge uses encapsulation, aggregation, and can use inheritance to separate responsibilities into different classes.
[4] Tammis Keefe, a cloth designer whose patterns appeared at Lord and Taylor in September 1952, used a harlequin print diamond pattern on a large cloth she crafted for a table setting show.
