App Inventor For Android
MIT App Inventor (App Inventor or MIT AI2) is a high-level block-based visual programming language, originally built by Google and now maintained by the Massachusetts Institute of Technology (MIT). It allows newcomers to create computer applications for two operating systems: Android and iOS, which, , was in beta testing. It is free and open-source released under dual licensing: a Creative Commons Attribution ShareAlike 3.0 Unported license and an Apache License 2.0 for the source code. It's target is primarily children and students studying computer programming, similar to Scratch. The web interface consists of a graphical user interface (GUI) very similar to Scratch and StarLogo, allowing users to drag-and-drop visual objects (blocks) to create an application that can be tested on Android and iOS devices and compiled to run as an Android app. It uses a companion mobile app named MIT AI2 Companion providing live testing and debugging.

Hal Abelson
Harold Abelson (born April 26, 1947) is an American mathematician and computer scientist. He is a professor of computer science and engineering in the Department of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology (MIT), a founding director of both Creative Commons and the Free Software Foundation, creator of the MIT App Inventor platform, and co-author of the widely-used textbook ''Structure and Interpretation of Computer Programs'' (SICP), sometimes also referred to as "the wizard book" because of its cover illustration. He directed the first implementation of the language Logo (programming language), Logo for the Apple II, which made the language widely available on personal computers starting in 1981; and published a widely selling book on Logo in 1982. Together with Gerald Jay Sussman, Abelson developed MIT's introductory computer science subject, "The Structure and Interpretation of Computer Programs" (often referred to by the MIT cour ...

Visual Programming Language
In computing, a visual programming language (visual programming system, VPL, or, VPS), also known as diagrammatic programming, graphical programming or block coding, is a programming language that lets users create computer program, programs by manipulating program elements rather than by specifying them . A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. For example, many VPLs are based on the idea of "boxes and arrows", where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations. VPLs are generally the basis of low-code development platforms. Definition VPLs may be further classified, according to the type and extent of visual expression used, into icon-based languages, form-based languages, and diagram languages. Visual programming environments provide graphical or iconic elements which can be manipulated by u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blockly
Blockly is a client-side library for the programming language JavaScript for creating block-based visual programming languages (VPLs) and editors. A project of Google, it is free and open-source software released under the Apache License 2.0. It typically runs in a web browser, and visually resembles the language Scratch. Blockly uses visual blocks that link together to make writing code easier, and can generate code in JavaScript, Lua, Dart, Python, or PHP. It can also be customized to generate code in any textual programming language. History Blockly development began in summer 2011. The first public release was in May 2012 at Maker Faire. Blockly was originally designed as a replacement for ''OpenBlocks'' in App Inventor. Neil Fraser began the project with Quynh Neutron, Ellen Spertus, and Mark Friedman as contributors. User interface The default graphical user interface (GUI) of the Blockly editor consists of a toolbox, which holds available blocks, and where a use ...

MIT License
The MIT License is a permissive software license originating at the Massachusetts Institute of Technology (MIT) in the late 1980s. As a permissive license, it puts very few restrictions on reuse and therefore has high license compatibility. Unlike copyleft software licenses, the MIT License also permits reuse within proprietary software, provided that all copies of the software or its substantial portions include a copy of the terms of the MIT License and also a copyright notice. In 2015, the MIT License was the most popular software license on GitHub, and was still the most popular in 2025. Notable projects that use the MIT License include the X Window System, Ruby on Rails, Node.js, Lua (programming language), Lua, jQuery, .NET, Angular (web framework), Angular, and React (JavaScript library), React. License terms The MIT License has the identifier MIT in the SPDX License List. It is also known as the "#Ambiguity and variants, Expat License". It has the following terms: Co ...

Hour Of Code
Code.org is a non-profit organization and educational website founded by Hadi and Ali Partovi, aimed at K-12 students who specialize in computer science. The website includes free coding lessons and other resources. The initiative also targets schools in the United States in an attempt to encourage them to include more computer science classes in the curriculum. In 2013, they launched the Hour of Code across the United States to promote computer science during Computer Science Education Week. History Code.org was launched in January 2013 by Iranian-American brothers Hadi Partovi and Ali Partovi, as a non-profit focused on making computer programming more accessible. The initial focus was on creating a database of all computer science classrooms in the United States. At the time, Hadi Partovi stated that about ninety percent of US schools do not teach programming, despite it now being a "foundational field". The idea for the organization came from Hadi, who states that he thought ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firebase
Firebase was a company that developed backend software. It was founded in San Francisco in 2011 and was incorporated in Delaware. In 2014, Firebase was bought by Google. Its name continues as a set of backend cloud computing services and application development platforms provided by Google. It hosts databases, services, authentication, and integration for a variety of applications, including Android, iOS, JavaScript, Node.js, Java, Unity, PHP, and C++. History Firebase evolved from Envolve, a prior startup founded by James Tamplin and Andrew Lee in 2011. Envolve provided developers an API that enables the integration of online chat functionality into their websites. After releasing the chat service, Tamplin and Lee found out that it was being used to pass application data that were not chat messages. Developers were using Envolve to sync application data such as game state in real time across their users. Tamplin and Lee decided to separate the chat system and the re ...

Computer Programming
Computer programming or coding is the composition of sequences of instructions, called computer program, programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing source code, code in one or more programming languages. Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit. Proficient programming usually requires expertise in several different subjects, including knowledge of the Domain (software engineering), application domain, details of programming languages and generic code library (computing), libraries, specialized algorithms, and Logic#Formal logic, formal logic. Auxiliary tasks accompanying and related to programming include Requirements analysis, analyzing requirements, Software testing, testing, debugging (investigating and fixing problems), imple ...
