	abstraction - a definition from Whatis.com
		Abstraction (from the Latin abs, meaning away from and trahere, meaning to draw) is the process of taking away or removing characteristics from something in order to reduce it to a set of essential characteristics.
		In object-oriented programming, abstraction is one of three central principles (along with encapsulation and inheritance).
		In the process of abstraction, the programmer tries to ensure that the entity is named in a manner that will make sense and that it will have all the relevant aspects included and none of the extraneous ones.

	Abstraction physics
		The physics of abstraction is of an outside looking in perspective, where rather than creating another abstract language (inside), instead sees the underlying action machinery enabling the ability to create languages (outside looking in).
		Abstraction enters the picture of computing with the representation of physical transistor switch positions of ON '1' and OFF '0' or what we call "Binary notation".
		Programming is the act of automating some level of complexity, usually made up of simpler complexities, but done so in order to allow the user to use and reuse the complexity through a simplified interface.

	EDGE Digerati: The WYSIWYG - Charles Simonyi [page 2]
		So an abstraction may be looked at from one side as a compression of many instances into one generality or from the other side as a special purpose power tool that yields the solution for many problems.
		People think of programming languages as being good or bad for a given purpose, but they are really criticizing the abstractions that a language embodies.
		IP programs are encoded in a tree-like data structure where each node also has a graph-like pointer to the definition of the intention the node is an instance of.

	Abstraction (computer science) - Wikipedia, the free encyclopedia
		An example of this abstraction process is the generational development of programming languages from the machine language to the assembly language and the high-level language.
		In functional programming languages, it is common to find abstractions related to functions, such as lambda abstractions (making a term into a function of some variable), higher-order functions (parameters are functions), bracket abstraction (making a term into a function of a variable).
		Data abstraction is the enforcement of a clear separation between the abstract properties of a data type and the concrete details of its implementation.

	Glossary
		A parallel program that generates relatively small numbers of huge messages may be limited by the bandwidth of the network in which case it is called a ``bandwidth limited'' program.
		Incremental parallelism is a technique for parallelizing an existing program, in which the parallelization is introduced as a sequence of incremental changes, parallelizing one loop at a time.
		Programs that generate large numbers of small messages are sensitive to the latency and are called latency bound programs.

	Abstractions -- The Building Substance of Programming Languages
		In this second meaning, abstraction is a process by which the programmer associates a name with a potentially complicated program fragment, which can then be thought of in terms of its purpose of function, rather than in terms of how that function is achieved.
		Closed syntactic abstraction: The names occuring in E are bound relative to the point of definition or application, resp.
		Data is an abstraction, capable of representation in many forms, and "datatype" is a more abstract still; it is disastrous to link the concept to particular representational forms.

	[No title]
		Abstraction can be defined as: A model of a complex system that includes only the essential details relative to the perspective of a viewer of the system.
		Encapsulation is the concentration of all program text dependent on a particular design choice in one place.: structure to represent the abstract data type along with the operations for that type in a single package.
		Data abstraction, also allows for separation of concerns: allowing you to understand the rest of the program in terms of how the abstract data type is used, without considering the details of manipulating the underlying data structure.

	History of Thinking 4
		I don't mean to suggest that programming is a new form of writing in the same way that algebra is a new form of writing, or musical notation is a new form of writing.
		Programming, by contrast, has nonlinearity built into its deepest structures; the basis of this nonlinearity is called "branching", and all programming languages, even the simplest, have some form of branching.
		As with abstraction, branching is conjugated in programming with all the rigor of a Latin verb, and enjoys the same expressive precision.

	Object Oriented Programming
		An "object-oriented program consists of a group of cooperating objects, exchanging messages, for the purpose of achieving a common objective." Four of the most important principles of OOP are: data abstraction, modular programming, encapsulation, and inheritance.
		Data abstraction is the principle of organizing data to permit efficient access and update in a given application context.
		Modular programs are easier to update and maintain since small changes are localized to a small number of modules.

	Abstractionless programming \| Lambda the Ultimate
		So the idea is to have a language where it is impossible to create abstractions, but rather the programming environment continuously refactors for you as you edit (yes this is a tall order, bear with me).
		This way, even functional abstraction can be created without the user even knowing what it is (creating a local change in a shared subtree is like having an argument to a function).
		Abstractions will not be stable, but you should care less: as you don't have to maintain them, just be able to read them.

	Modern C++ Style
		Data abstraction was basically the way you wrote code in Ada and a whole slurry of other languages.
		Data abstraction is very good for dealing with high performance numerical problems where you have lots of rellatively standard concepts, such as complex number, vector, and upper-diagonal matrix, that must be efficiently implemented to be useful and that can be represented as relatively independent classes.
		When you look at my earlier writings, there was usually a section under data abstraction that said, "and we need to parameterize our containers with the element type and do operations on parameterized containers." This is what later grew to be generic programming.

	online C++ tutorial: Programming Languages
		As a loose definition, a programming language is a tool used by a programmer to give the computer very specific instructions in order to serve some purpose for the user.
		Programming languages were created so developers could express their ideas on a higher level than a computer can understand.
		A programming language is a tool used by programmers in order to specifically outline a series of steps that a computer is to take in a certain instance.

	Object-Orientation and C++
		The purpose of abstraction in programming is to separate behavior from implementation.
		One disadvantage of procedural abstraction is its loose coupling between the procedure and the data it manipulates.
		Recall that the importance of data abstraction is to hide the implementation details of a data object from the user.

	Teaching Programming Lqnguages by Counter-Example
		The programming languages course is a key component of the computer science curriculum.
		Students learn to discern between various paradigms and their concomitant abstractions, to judge the utility of various language designs, and to appreciate the impact that implementation decisions have on languages.
		In the programming languages design and implementation course, we advocate retaining the traditional subject matter and organization (i.e., different paradigms, abstractions, and concepts).

	Abstraction inversion - Wikipedia, the free encyclopedia
		In computer programming, abstraction inversion is an anti-pattern arising when the interface to a construct does not expose the functions needed by its users, although they are used within the construct.
		The term "abstraction inversion" is sometimes misunderstood as referring to complex (or concrete) constructs with simple (or abstract) interfaces, which are normal and desirable.
		The article 'Microkernel' at tunes.org gives many of the arguments against microkernels and suggests that it is an abstraction inversion to implement a modular high-level design using a low-level module manager.

	Design Patterns in Web Programming
		But web programming as we know it is really only a few years old and this presentation is a solo effort.

	The Law of Leaky Abstractions - Joel on Software
		The abstraction of "remote file is the same as local file" leaks.
		If you put users' home directories on NFS-mounted drives (one abstraction), and your users create.forward files to forward all their email somewhere else (another abstraction), and the NFS server goes down while new email is arriving, the messages will not be forwarded because the.forward file will not be found.
		In teaching someone about COM programming, it would be nice if I could just teach them how to use the Visual Studio wizards and all the code generation features, but if anything goes wrong, they will not have the vaguest idea what happened or how to debug it and recover from it.

	The Future of Programming
		Perhaps the early days of programming computers by flicking switches and feeding in punched cards is closest to that dance, but it is still a level of abstraction that permitted us to communicate with our lovingly created inanimate servants.
		The programs that form their 'real' existence have to understand data in the same way we see things, and respond to changes (like movement) forced on them by their environment.
		Virtual people assemble 'programs' (which are virtual artefacts really) from components and raw materials with certain properties, perhaps applying filters like textures and plugging in data storage blocks and defining triggers for patterns of behaviour.

		These vary in terms of the programming abstractions they provide and the kinds of heterogeneity they provide beyond network and hardware.
		Distributed object middleware provides the abstraction of an object that is remote yet whose methods can be invoked just like those of an object in the same address space as the caller.
		The abstractions offered by various middleware frameworks can be used to provide resource management in a distributed system at a higher level than is otherwise possible.
