"OK Log is a distributed and coördination-free log management system for big ol' clusters. I built it from first principles, to teach myself the gory details of shuffling logs around. This is the story of the prototype."

"Spring Data Rest is makes it easy to build hypermedia-driven REST web services. This lib provider useful util to play with the service in js. It's a easy to use and lightweight (2kb after min and gzip) javascript lib can run in both node.js and browser,can be work with lib like AngularJS React Vue. support Typescript."

Streaming path filter node factory for continuous queries and/or transformations over very large or infinitely long XML input.

Data.js is a data representation framework for Javascript. It is being developed in the context of Substance, a web-based document authoring and publishing engine. It took some inspiration from various existing libraries such as the Google Visualization API or Underscore.js.  You can report bugs and discuss features on the GitHub issues page, on Freenode IRC in the #_substance chann el, post questions to the Google Group, or send tweets to @_substance. With Data.js you can: Model your domain data using a simple graph-based object model that can be serialized to JSON. Traverse your graph, including relationships using a simple API. Manipulate and query data on the client (browser) or on the server (Node.js) by using exactly the same API. 

"In this paper we propose the TurboXPath path processor, which accepts a language equivalent to a subset of the for-let-where constructs of XQuery over a single document. TurboXPath can be extended to provide full XQuery support or used to augment federated database engines for efficient handling of queries over XML data streams produced by external sources. Internally, TurboXPath uses a tree-shaped path expression with multiple outputs to drive the execution. The result of a query execution is a sequence of tuples of XML fragments matching the output nodes. Based on a streamed execution model, TurboXPath scales up to large documents and has limited memory consumption for increased concurrency"

"RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code."

Passport is authentication middleware for Node.js. Extremely flexible and modular, Passport can be unobtrusively dropped in to any Express-based web application. A comprehensive set of strategies support authentication using a username and password, Facebook, Twitter, and more."

"A network daemon that runs on the Node.js platform and listens for statistics, like counters and timers, sent over UDP or TCP and sends aggregates to one or more pluggable backend services (e.g., Graphite)."

"Consul has multiple components, but as a whole, it is a tool for discovering and configuring services in your infrastructure. It provides several key features: Service Discovery: Clients of Consul can provide a service, such as api or mysql, and other clients can use Consul to discover providers of a given service. Using either DNS or HTTP, applications can easily find the services they depend upon. Health Checking: Consul clients can provide any number of health checks, either associated with a given service ("is the webserver returning 200 OK"), or with the local node ("is memory utilization below 90%"). This information can be used by an operator to monitor cluster health, and it is used by the service discovery components to route traffic away from unhealthy hosts. Key/Value Store: Applications can make use of Consul's hierarchical key/value store for any number of purposes including: dynamic configuration, feature flagging, coordination, leader election, etc. The simple HTTP API makes it easy to use. Multi Datacenter: Consul supports multiple datacenters out of the box. This means users of Consul do not have to worry about building additional layers of abstraction to grow to multiple regions. Consul is designed to be friendly to both the DevOps community and application developers, making it perfect for modern, elastic infrastructures."

"Trireme runs Node.js scripts inside the JVM."

ShareJS is an Operational Transform library for NodeJS & browsers. It lets you easily do live concurrent editing in your app.

Assessing the effect of different programming languages and programming styles on programmer productivity is of critical interest. In his paper, Gilles Dubochet, describes how he investigated two aspects of programming style using eye movement tracking. He found that it is, on average, 30% faster to comprehend algorithms that use for-comprehensions and maps, as in Scala, rather than those with the iterative while-loops of Java.

"Babel is a JavaScript compiler. Use next generation JavaScript, today."

¡Muy buenas!

The [docker registry](https://registry.hub.docker.com/) is bursting at the seams. At the time of this writing, a search for "node" gets just under 1000 hits. How does one choose? ## What constitutes a good docker image? This is a subjective matter, but I have some criteria for a docker image that I consider good: * **working**.

Decking aims to simplify the creation, organsation and running of clusters of Docker containers in a way which is familiar to developers; by reading information from a decking.json package file on a project by project basis. You can view a showterm recording of decking in action or check out a simple example project.
