Lego in duplo


http://gadgets.fosfor.se/lego-patent-turns-50/

Dit is geen tikfout, het moet niet zijn lego en duplo.
Voor de insiders: duplo betekent alles in tweevoud.

In deze context mag dit artikel niet ontbreken:

Prerequisite one: Components. To develop software based on the LEGO brick principle means, of course, that there are “LEGO bricks,” or components, available. A component can be defined as “a piece of software that is only accessible via its interfaces.” A component provides one or more business services. These services can be relied upon, or certified, and the component can then be used in conjunction with other components to rapidly assemble a complex business support infrastructure, which is inherently adaptable and of high quality.

Of deze (pas op: uit de vorige eeuw!):

En zeker niet deze over het object-oriented paradigm:

It is claimed that object-oriented (OO) technology is the "Silver Bullet" that can be used to solve the software crisis [1] . Proponents of object oriented analysis, design, and programming describe how these approaches lead to systems which are faster to design, easier to build and maintain, are less complex and are more readily understood [2] . These qualities emerge from the interaction of the core features of the paradigm: encapsulation, binding data & behavior, and classification and inheritance. OO is a computer science discipline and the tools, methodologies and goals of object oriented design reflect computer science values. At the same time, OO is meant to create systems that are models of users' application domains. The increasingly popular object-oriented design techniques based on object modeling are centered on this design goal [2-5] . The domain-based object model has a "stronger equivalence" than traditional approaches [6] and hypothetically allows, systems developed using OO methods to be more easily comprehended and communicated [7] .
