In the Beginning... ...there was no inheritance and no composition, only code. And the code was unwieldy, repetitive, blocky, unhappy, verbose, and tired. Copy and Paste were the primary mechanisms of code reuse. Procedures and functions were rare, newfangled gadgets viewed with suspicion. Calling a procedure was expensive! Separating pieces of code from the main logic caused confusion! It was a Dark Time.

Background I've been to a few talks on SOLID before. Most of the principles seem pretty reasonable to me – but I've never "got" the open-closed principle (OCP from here on). At CodeMash this year, I mentioned this to the wonderful Cori Drew, who said that she'd been at a user group talk where she…
In summary, Smalltalk's specification-like coding and incremental development environment permits a unique human-human-machine dialogue. CRC Cards allow larger groups to feel this dialogue which is based on repeated episodes of decision making. Finally, members of somewhat larger production development teams can exploit the human-human-machine dialogue on a pair-wise basis. The complex communication that then takes place will support a High-Performance organization with many benefits, a few of which I have mentioned.
http://www.purl.org/stefan_ram/pub/doc_kay_oop_en http://userpage.fu-berlin.de/~ram/pub/pub_jf47ht81Ht/begriff_objektorientierte_programmierung_de Alan Kay coined the phrase Object-Oriented Programming, but this is not his fault. He has repeatedly said that to him, OOP is about encapsulation and message passing, not inheritance and ontologies of types. But like so many other Cargo Cults in Computer Programming culture, OOP and inheritance are enchained like ancient mariner and albatross

there's been a rush of lightweight containers that help to assemble components from different projects into a cohesive application. Underlying these containers is a common pattern to how they perform the wiring
a prototype-based object-oriented programming language based on Self, CLOS, and Smalltalk-80. Slate syntax is intended to be as familiar as possible to a Smalltalker, for the clarity of messages as phrases. Unlike the Smalltalk family, methods within Slat
a new programming language. It extends the ideas behind object-orientation in order to better support modular programming and static type safety. It also incorporates features from functional programming, and puts into practice state-of-the-art results fr
The Unified Modeling Language has quickly become the de-facto standard for building Object-Oriented software. This tutorial provides a technical overview of the 13 UML.
