Computation

An application-centric, decentralised and distributed computing solution.

RubyVor provides efficient computation of Voronoi diagrams and Delaunay triangulation for a set of Ruby points. It is intended to function as a complemenet to GeoRuby. These structures can be used to compute a nearest-neighbor graph for a set of points. This graph can in turn be used for proximity-based clustering of the input points.

Ruby/CArray is an extension library for the multi-dimensional numerical array class. The name "CArray" comes from the meaning of a wrapper to a numerical array handled by the C language. CArray stores integers or floating-point numbers in memory block and treats them collectively to ensure efficient performance. Therefore, Ruby/CArray is suitable for numerical computation and data analysis.

The Infochimps Platform is an end-to-end, managed solution for building Big Data applications. It integrates best-of-breed technologies like Hadoop, Storm, Kafka, MongoDB, ElasticSearch, HBase, &c. and provides simple interfaces for accessing these powerful tools. Computation, analytics, scripting, &c. are all handled by Wukong within the platform. Wukong is an abstract framework for defining computations on data. Wukong processors and flows can run in many different execution contexts including: * locally on the command-line for testing or development purposes * as a Hadoop mapper or reducer for batch analytics or ETL * within Storm as part of a real-time data flow The Infochimps Platform uses the concept of a deploy pack for developers to develop all their processors, flows, and jobs within.

SciCom (Scientific Computing) for Ruby brings the power of R to the Ruby community. SciCom is based on Renjin, a JVM-based interpreter for the R language for statistical computing. Over the past two decades, the R language for statistical computing has emerged as the de facto standard for analysts, statisticians, and scientists. Today, a wide range of enterprises – from pharmaceuticals to insurance – depend on R for key business uses. Renjin is a new implementation of the R language and environment for the Java Virtual Machine (JVM), whose goal is to enable transparent analysis of big data sets and seamless integration with other enterprise systems such as databases and application servers. Renjin is still under development, but it is already being used in production for a number of client projects, and supports most CRAN packages, including some with C/Fortran dependencies. SciCom integrates with Renjin and allows the use of R inside a Ruby script. In a sense, SciCom is similar to other solutions such as RinRuby, Rpy2, PipeR, etc. However, since SciCom and Renjin both target the JVM there is no need to integrate both solutions and there is no need to send data between Ruby and R, as it all resides in the same JVM. Further, installation of SciCom does not require the installation of GNU R; Renjin is the interpreter and comes with SciCom. Finally, although SciCom provides a basic interface to Renjin similar to RinRuby, a much tighter integration is also possible.

GRATR is a framework for graph data structures and algorithms. This library is a fork of RGL. This version utilizes Ruby blocks and duck typing to greatly simplfy the code. It also supports export to DOT format for display as graphics. GRATR currently contains a core set of algorithm patterns: * Breadth First Search * Depth First Search * A* Search * Floyd-Warshall * Best First Search * Djikstra's Algorithm * Lexicographic Search The algorithm patterns by themselves do not compute any meaningful quantities over graphs, they are merely building blocks for constructing graph algorithms. The graph algorithms in GRATR currently include: * Topological Sort * Strongly Connected Components * Transitive Closure * Rural Chinese Postman * Biconnected

pocketknife is a devops tool for managing computers running chef-solo, powered by Opscode Chef. Using pocketknife, you create a project that describes the configuration of your computers and then deploy it to bring them to their intended state. With pocketknife, you don't need to setup or manage a specialized chef-server node or rely on an unreliable network connection to a distant hosted service whose security you don't control, deal with managing chef's security keys, or deal with manually synchronizing data with the chef-server datastore. With pocketknife, all of your cookbooks, roles and nodes are stored in easy-to-use files that you can edit, share, backup and version control with tools you already have.

Proper related posts plugin for Jekyll - uses document correlation matrix on TF-IDF (optionally with Latent Semantic Indexing). Each document is tokenized and stemmed, every word found is treated as keyword for analysis (except for some stop words). TF-IDF matrix for the whole site is calculated (including extra provided weights), then if given accuraccy is lower than 1.0, LSI algorithm is used to compute new simplified vector space. Document correlation matrix is created using dot product of the matrix and its transpose. For each of the post' related documents are inserted into priority queue (sorted by score from document correlation matrix), assuming the score is greater than minimal required score. Selected few bests related posts are retrieven from the queue. Liquid template for each post is rendered and <related-posts /> is replaced with the outcomes of algorithm.
