Scale Scaling in Tsuru is completely painless. Just add a unit and Tsuru will take care of everything else. Extend Tsuru is built to be extensible. Through services you can provide anything your application needs."

"general purpose extensions to golang's database/sql "

SubScript, a way to extend common programming languages aimed to ease event handling and concurrency. Typical application areas are GUI controllers, text processing applications and discrete event simulations. SubScript is based on a mathematical concurrency theory named Algebra of Communicating Processes (ACP). ACP is a 30-year-old branch of mathematics, as solid as numeric algebra and as Boolean algebra. In fact, you can regard ACP as an extension to Boolean algebra with 'things that can happen'. These items are glued together with operations such alternative, sequential and parallel compositions. This way ACP combines the essence of grammar specification languages and notions of parallelism.

A collection of Git extensions to provide high-level repository operations for Vincent Driessen's branching model.

SoftNAS™ is business-class network attached storage (NAS) delivered as software as a service.  The NAS software virtual appliance runs within your cloud computing environment (e.g., Amazon EC2) or local virtual server environment (e.g., VMware vSphere) and manages the available raw disk storage, providing enterprise-grade storage capabilities. SoftNAS leverages a number of open source technologies, including ZFS on Linux.  ZFS on Linux is a port of the popular ZFS filesystem originally produced by Sun Microsystems and released with OpenSolaris.  SoftNAS builds on the robust, solid foundation of ZFS and its powerful, extensible Linux foundation.

"At DataSift, we've standardised on using Git for our source control, using GitHub to host our public and private Git repositories, and using GitFlow as our common workflow This website explains how we've adapted GitFlow and the GitFlow tools git extension for working with GitHub. This is how we work internally, and we're sharing this in the hope that others find it useful too."

In January of this year, @nvie published "A successful Git branching model", in which he explained how he keeps his Git repositories nice and tidy. In addition to that, he released git-flow; a bunch of Git extensions to make following this model extremely easy. I'm astounded that some people never heard of it before, so in this article I'll try to tell you why it can make you happy and cheerful all day.

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.

"The goal of this document is to serve as a starting point for the student of Haskell wishing to gain a firm grasp of its standard type classes. The essentials of each type class are introduced, with examples, commentary, and extensive references for further reading."

"Our project (titled xstream)  concentrated on evaluation of XPath over XML streams. This research area contains multiple challenges resulting  from both the richness  of the language and the requirement of having only a single  pass over the data. We modified and extended one of the known algorithms, TurboXPath  [4], a tree-based IBM algorithm. We also  provide extensive comparative analysis between  TurboXPath and XSQ [5], currently the most advanced of  finite automata (FA)-based algorithms."

"Blueprints is a property graph model interface. It provides implementations, test suites, and supporting extensions. Graph databases and frameworks that implement the Blueprints interfaces automatically support Blueprints-enabled applications. Likewise, Blueprints-enabled applications can plug-and-play different Blueprints-enabled graph backends."

"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."

"Configuration library for JVM languages. Overview implemented in plain Java with no dependencies extensive test coverage supports files in three formats: Java properties, JSON, and a human-friendly JSON superset merges multiple files across all formats can load from files, URLs, or classpath good support for "nesting" (treat any subtree of the config the same as the whole config) users can override the config with Java system properties, java -Dmyapp.foo.bar=10 supports configuring an app, with its framework and libraries, all from a single file such as application.conf parses duration and size settings, "512k" or "10 seconds" converts types, so if you ask for a boolean and the value is the string "yes", or you ask for a float and the value is an int, it will figure it out. JSON superset features: comments includes substitutions ("foo" : ${bar}, "foo" : Hello ${who}) properties-like notation (a.b=c) less noisy, more lenient syntax substitute environment variables This library limits itself to config files. If you want to load config from a database or something, you would need to write some custom code. The library has nice support for merging configurations so if you build one from a custom source it's easy to merge it in."

"Java 8 also brings many security improvements that are as important as the new language features. Of particular interest are the improvements to the TLS stack, implemented in the Java Secure Socket Extension (JSSE) component. Why? Because Java 7 and earlier do not give you enough control over TLS termination. As a result, it was simply not possible to terminate TLS at the Java level and achieve sufficient security. The deficiencies have been addressed in Java 8. Several other key improvements ensure that Java now provides a very good TLS stack. Many of the changes will take effect as you change the JRE, even with older applications."

"This page contains tables of known HTML rel values from specifications, formats, proposals, brainstorms, and non-trivial POSH usage in the wild. In addition, dropped and rejected values are listed at the end for comprehensiveness. usage: see how is 'rel' used. Regarding rev, see: should 'rev' even be used. This page is also the official rel registry ([1][2]). Add new and proposed rel values to the following section: HTML5 link type extension "

MonoHelper offers XBuild integration into Visual Studio, so you can use Mono within Visual Studio (Build & Run). When using XBuild or XRebuild command, MonoHelper detects current installed Mono Runtime or use preconfigured installation path, call XBuild with current configuration settings and outputs the results into the Output Console. It also generates pdb symbol files, so you can debug XBuild compiled programs with Visual Studio (running with .NET Runtime - see Stackoverflow about how this is done). If you want to run your program with installed Mono runtime, this is also possible.

"Powerstrip is implemented as a configurable, pluggable HTTP proxy for the Docker API which lets you plug multiple Docker extension prototypes into the same Docker daemon."

"1. The Government has already made a commitment to Big Data by classifying it as one of the 'Eight Great Technologies' which will propel the UK to future growth and help it stay ahead in the global race. The 'Information Economy Strategy' reports on the increase in data being generated and the importance of new types of computing power in order to reap the economic value of the data. 2. This paper sets out to cover the following areas: a) Defining Big Data b) High-level trends in Big Data c) Opportunities for Big Data applications 3. In developing this paper, a 'community of interest' has been established comprising policy leads and analysts from across government with an interest in Big Data. This paper draws on their insights, insights from the private sector, academics, and the extensive open source literature on the Big Data topic."

Luna is a data processing and visualization environment built on a principle that people need an immediate connection to what they are building. It provides an ever-growing library of highly tailored, domain specific components and an extensible framework for building new ones.
