ELIZA - Wikipedia, the free encyclopedia - 0 views

  • ELIZA was a computer program and an early example (by modern standards) of primitive natural language processing. ELIZA operated by processing users' responses to scripts, the most famous of which was DOCTOR, a simulation of a Rogerian psychotherapist. In this mode, ELIZA mostly rephrased the user's statements as questions and posed those to the 'patient.' ELIZA was written by Joseph Weizenbaum between 1964 to 1966

Neuroplasticity - Wikipedia, the free encyclopedia - 0 views

  • Neuroplasticity (also referred to as brain plasticity, cortical plasticity or cortical re-mapping) is the changing of neurons and the organization of their networks and so their function by experience. This idea was first proposed in 1892 by Santiago Ramón y Cajal the proposer of the neuron doctrine though the idea was largely neglected for the next fifty years.[1] The first person to use the term neural plasticity appears to have been the Polish neuroscientist Jerzy Konorski.[2]

      This is why when a person thinks more he/she be more smarter!
    • Abdelrahman Ogail
       
      How said that? It's related to Artificial Neural Networks that require understanding of actual Human Neurons. BTW, plasticity principle is used in Games AI where the Controlled-AI determines if it forgot what happened or still remember it and seeks to revenge

Deep Blue (chess computer) - Wikipedia, the free encyclopedia - 0 views

  • Deep Blue was a chess-playing computer developed by IBM. On May 11, 1997, the machine won a six-game match by two wins to one with three draws against world champion Garry Kasparov.[1] Kasparov accused IBM of cheating and demanded a rematch, but IBM declined and dismantled Deep Blue.[2] Kasparov had beaten a previous version of Deep Blue in 1996

      When AI beats humanity!
  • Deep Blue was then heavily upgraded (unofficially nicknamed "Deeper Blue")[11] and played Kasparov again in May 1997, winning the six-game rematch 3½–2½, ending on May 11, finally ending in game six, and becoming the first computer system to defeat a reigning world champion in a match under standard chess tournament time controls.

  • OL (also written with some or all letters lowercase) is an abbreviation for laughing out loud[1][2] or laugh out loud.[3] LOL is a common element of Internet slang used historically on Usenet, but now widespread in other forms of computer-mediated communication, and even face-to-face communication. It is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms such as ROTFL[4][5][6][7] or ROFL [8] ("roll(ing) on the floor laughing"), a more emphatic expression of laughter, and BWL ("bursting with laughter"), above which there is "no greater compliment" according to technology columnist Larry Magid.[9] Other unrelated expansions include the now mostly historical "lots of luck" or "lots of love" used in letter-writing.[10

  • An Abstract Agent Programming Language or Artificial Autonomous Agents Programming Language or 3APL (pronounced triple-A-P-L) is an experimental tool and programming language for the development, implementation and testing of multiple cognitive agents using the Belief-Desire-Intention (BDI) approach. The newest incarnation of 3APL is 2APL (A Practical Agent Programming Language).

CodeProject: C# vs C/C++ Performance. Free source code and programming help - 0 views

  • is compiled twice. Once while the program is written and second when the program is executed at the user's site. The first compilation is done by your C# builder and the second by the .NET Framework on the user's machine. The reason why C# compiled applications could be faster is that, during the second compilation, the compiler knows the actual run-time environment and processor type and could generate instructions that targets a specific processor.
  • A well designed C# program is more than 90% as fast as an equivalent "well-designed" C++ program
  • The problem with "not-freeing" the memory at the right time is that the working set of the application increases which increases the number of "page faults"
  • ...1 more annotation...
  • That's a nice question. Except for writing time-critical blocks of code, prefer C#. Write all your algorithmic code in C++ (not VC++ .NET), compile it into a dll and call that using a Dll Interop through C#. This should balance the performance. This technique is not new or not invented by me or anyone. It's similar the old age C programming vs Assembly, where people on one camp fight assembly programming is faster and the other camp stating C is easier to develop and then people started using assembly embedded within a C program for time-critical applications using an asm block.

How to Use the Windiff.exe Utility - 0 views

  • This article describes how to use the Windiff.exe utility, a tool that graphically compares the contents of two ASCII files, or the contents of two folders that contain ASCII files, to verify whether they are the same. The file byte count and the creation date are not reliable indications.

Uniform Resource Identifier - Wikipedia, the free encyclopedia - 0 views

shared by Abdelrahman Ogail on 16 Jun 09 - Cached
  • In computing, a Uniform Resource Identifier (URI) consists of a string of characters used to identify or name a resource on the Internet. Such identification enables interaction with representations of the resource over a network (typically the World Wide Web) using specific protocols. Schemes specifying a specific syntax and associated protocols define each URI. Contents [hide]

Scalability - Wikipedia, the free encyclopedia - 0 views

  • In telecommunications and software engineering, scalability is a desirable property of a system, a network, or a process, which indicates its ability to either handle growing amounts of work in a graceful manner, or to be readily enlarged.[1] For example, it can refer to the capability of a system to increase total throughput under an increased load when resources (typically hardware) are added. An analogous meaning is implied when the word is used in a commercial context, where scalability of a company implies that the underlying business model offers the potential for economic growth within the company.
    • Abdelrahman Ogail
       
      In web applications, the client objects are removed from the server when they are sent to the client browser. This is great for scalability, but it can hurt the user and developer experience
    • Abdelrahman Ogail
       
      In Web applications client data are saved on the server (then the server memory is decreased that decreases the scalability - الإستيعاب-) So removing the client data improvers scalability becuase it saves server memory

Belief-Desire-Intention software model - Wikipedia, the free encyclopedia - 0 views

  • The Belief-Desire-Intention (BDI) software model (usually referred to simply, but ambiguously, as BDI) is a software model developed for programming intelligent agents. Superficially characterized by the implementation of an agent's beliefs, desires and intentions, it actually uses these concepts to solve a particular problem in agent programming. In essence, it provides a mechanism for separating the activity of selecting a plan (from a plan library) from the execution of currently active plans. Consequently, BDI agents are able to balance the time spent on deliberating about plans (choosing what to do) and executing those plans (doing it). A third activity, creating the plans in the first place (planning), is not within the scope of the model, and is left to the system designer and programmer.

      This model is used to simulate human behavior its under area of research and its so interesting and innovative

COUNT (Transact-SQL) - 0 views

  • COUNT(*) returns the number of items in a group. This includes NULL values and duplicates. COUNT(ALL expression) evaluates expression for each row in a group and returns the number of nonnull values. COUNT(DISTINCT expression) evaluates expression for each row in a group and returns the number of unique, nonnull values.

Ternary relation - Wikipedia, the free encyclopedia - 0 views

  • n mathematics, a ternary relation or triadic relation is a finitary relation in which the number of places in the relation is three. Ternary relations may also be referred to as 3-adic, 3-ary, 3-dimensional, or 3-place. Just as a binary relation is formally defined as a set of pairs, i.e. a subset of the Cartesian product A × B of some sets A and B, so a ternary relation is a set of triples, forming a subset of the Cartesian product A × B × C of three sets A, B and C.

Model-view-controller - Wikipedia, the free encyclopedia - 0 views

  • Model–view–controller (MVC) is an architectural pattern used in software engineering. Successful use of the pattern isolates business logic from user interface considerations, resulting in an application where it is easier to modify either the visual appearance of the application or the underlying business rules without affecting the other. In MVC, the model represents the information (the data) of the application; the view corresponds to elements of the user interface such as text, checkbox items, and so forth; and the controller manages the communication of data and the business rules used to manipulate the data to and from the model.
    • Abdelrahman Ogail
       
      MVC one of the important patterns used at any software. Especially in Web Development, Database Systems and sure in Game Development

Rich Internet application - Wikipedia, the free encyclopedia - 0 views

  • Rich Internet applications (RIAs) are web applications that have some of the characteristics of desktop applications, typically delivered by way of a proprietary web browser plug-ins or independently via sandboxes or virtual machines[1]. Examples of RIA frameworks include Curl (programming language), Adobe Flash/Adobe Flex/AIR, Java/JavaFX[2], uniPaaS[3] and Microsoft Silverlight[4].
