PhET Interactive Simulations, a project at the University of Colorado Boulder, is a non-profit [1] open educational resource project that creates and hosts explorable explanations. It was founded in 2002 by Nobel Laureate Carl Wieman. PhET began with Wieman's vision to improve the way science is taught and learned.
Scratch 3.0 User interface A program to change the background and make a character speak. The Scratch interface is divided into three main sections: a stage area, block palette, and a coding area to place and arrange the blocks into scripts that can be run by pressing the green flag or clicking on the code itself.
Consistent hashing. In computer science, consistent hashing [1] [2] is a special kind of hashing technique such that when a hash table is resized, only keys need to be remapped on average where is the number of keys and is the number of slots. In contrast, in most traditional hash tables, a change in the number of array slots causes nearly all ...
Virtual currency. Virtual currency, or virtual money, is a digital currency that is largely unregulated, issued and usually controlled by its developers, and used and accepted electronically among the members of a specific virtual community. [1] In 2014, the European Banking Authority defined virtual currency as "a digital representation of ...
Base Ten blocks for math. Virtual manipulatives for mathematics are digital representations of concrete mathematics manipulatives. [1] These virtual manipulatives are based on the physical manipulatives used in classrooms. They are generally used to introduce mathematical concepts using visuals and are used for teaching students new topics that ...
v. t. e. Eclipse Deeplearning4j is a programming library written in Java for the Java virtual machine (JVM). [2] [3] It is a framework with wide support for deep learning algorithms. [4] Deeplearning4j includes implementations of the restricted Boltzmann machine, deep belief net, deep autoencoder, stacked denoising autoencoder and recursive ...
Lean is a proof assistant and a functional programming language. [1] It is based on the calculus of constructions with inductive types. It is an open-source project hosted on GitHub. It was developed primarily by Leonardo de Moura while employed by Microsoft Research and now Amazon Web Services, and has had significant contributions from other ...
JRuby, a mixed Java and Ruby implementation that runs on the Java virtual machine. JRuby currently targets Ruby 3.1.x. TruffleRuby, a Java implementation using the Truffle language implementation framework with GraalVM; Rubinius, a C++ bytecode virtual machine that uses LLVM to compile to machine code at runtime. The bytecode compiler and most ...
