"pHash is an open source software library released under the GPLv3 license that implements several perceptual hashing algorithms, and provides a C-like API to use those functions in your own programs. pHash itself is written in C++."

shapeless is an exploration of generic (aka polytypic) programming in Scala derived from the various talks I've given over the course of 2011 on implementing scrap your boilerplate and higher rank polymorphism in Scala.

"The monad concept will be presented to an audience with the assumption of knowledge of the generics concept of either the Java or C# programming languages or some other form of parametric polymorphism. The concept will be presented in a way with the objective of supplying enough understanding to apply the practical implications and will not address the underlying mathematics or category theory."

Functional dependencies are a near-standard extension to Haskell (present in GHC and elsewhere) which allow constraints on the type parameters of type classes to be expressed and then enforced by the compiler.

Daniel Spiewak shows how to create immutable data that supports structural sharing, such as: Singly-linked List, Banker's Queue, 2-3 Finger Tree, Red-Black Tree, Patricia Trie, Bitmapped Vector Trie.

CopyFS aims to solve a common problem : given a directory, especially one full of configuration files, or other files that one can modify, and which can affect the functionning of a system, or of programs, that may be important to other users (or to the user himself), how to be sure that a person modifying the files will do a backup of the working version first ? This filesystem solves the problem by making the whole process transparent, automatically keeping versionned copies of all the changes done to file under its control. It also allows a user to select an old version of the files, for example to repair a mistake, and allows him/her to continue edition from this point.

Y otra intro a Monad y a su aplicación en scala. Particularmente simple y comprensible.

A core framework and next-generation shell for tooling and automation at a command line level; with APIs for integration in IDEs, extending built in functionality with plugins, and scripting for automating repetitive tasks, Forge is a tool every open-source developer should be looking at. A core framework for rapid-application development in a standards-based environment. Plugins / incremental project enhancement for Java EE, and more.

Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.

"Shark is a large-scale data warehouse system for Spark designed to be compatible with Apache Hive. It can execute Hive QL queries up to 100 times faster than Hive without any modification to the existing data or queries. Shark supports Hive's query language, metastore, serialization formats, and user-defined functions, providing seamless integration with existing Hive deployments and a familiar, more powerful option for new ones."

"Rapture I/O is a fledgling library for Scala which provides a consistent, intuitive and extensible API for handling common I/O operations, such as sending HTTP requests and streaming data between files, URLs and sockets. Rapture I/O offers the functionality of java.io, but unifies its features into simpler, more coherent and higher-level concepts, allowing tasks which once took several lines of code to be often accomplished in just one, taking full advantage of Scala's rich syntax."

"HPaste unlocks the rich functionality of HBase for a Scala audience. In so doing, it attempts to achieve the following goals: Provide a strong, clear syntax for querying and filtration Perform as fast as possible while maintaining idiomatic Scala client code -- the abstractions should not show up in a profiler! Re-articulate HBase's data structures rather than force it into an ORM-style atmosphere. A rich set of base classes for writing MapReduce jobs in hadoop against HBase tables. Provide a maximum amount of code re-use between general Hbase client usage, and operation from within a MapReduce job. Use Scala's type system to its advantage--the compiler should verify the integrity of the schema. Be a verbose DSL--minimize boilerplate code, but be human readable!"

"Buck is a build system for Android that encourages the creation of small, reusable modules consisting of code and resources. Because Android applications are predominantly written in Java, Buck also functions as a Java build system. Learn more about the strategies Buck uses to build Java code so quickly."

"Effective Go provides guidelines for naming packages, types, functions, and variables. This article expands on that discussion and surveys names found in the standard library. It also discusses bad package names and how to fix them."

"JavaScript is evolving and new ES2015 and ES2016 editions (previously known as ES6 and ES7, respectively) pack a bunch of new features and Babel makes it very easy to use of them today. These features make some previously essential functions from utility libraries obsolete."

"Pusher is a simple hosted API for quickly, easily and securely integrating realtime bi-directional functionality via WebSockets to web and mobile apps, or any other Internet connected device."

"URI.js is a javascript library for working with URLs. It offers a "jQuery-style" API (Fluent Interface, Method Chaining) to read and write all regular components and a number of convenience methods like .directory() and .authority(). URI.js offers simple, yet powerful ways of working with query string, has a number of URI-normalization functions and converts relative/absolute paths. While URI.js provides a jQuery plugin. URI.js itself does not rely on jQuery. You don't need jQuery to use URI.js"

Hola!. La vi el viernes a la manyana la libreria esta.Parece que esta buenisima. respecto a lo que yo tenia que hacer obviamente que puede ayudar con las funciones relative y absolute, pero por lo que definimos, "Construir las url's de los recursos a partir del raiz de la libreria", descarte su adopcion por parecerme de alguna forma "sobrecarga".Sea como sea, es una buena herramienta para adoptar. Buen finde.

Me acabo de dar cuenta.... Este articulo lo pusiste el 4. Estamos a la noche del 5 y recien me notifico. No es la primera vez, y ahora sospecho que son todas las veces las que cosas compartidas en diigo que se notifican con demora. Porque sera?
