The software includes the following features:

- Document-oriented storage: JSON-style documents with dynamic schemas offer simplicity and power.

- Full Index Support: Index on any attribute, just like you’re used to.

- Replication & High Availability. Mirror across LANs and WANs for scale and peace of mind.

- Auto-Sharding. Scale horizontally without compromising functionality.

- Querying. Rich, document-based queries.

- Fast In-Place Updates. Atomic modifiers for contention-free performance.

- Map/Reduce. Flexible aggregation and data processing.

- GridFS. Store files of any size without complicating your stack.

- Commercial Support. Enterprise class support, training, and consulting available.

It’s key features are as follows:

Easy to install

Because it is based on open source technologies and is platform-agnostic right out of the box, it is equally at home in Windows, *NIX, or Mac OS X environments.

Easy to use

Users log in with their real names, and are immediately taken to a task-pad view that shows all of the functions and reports that they are permitted to access. Creating work entries, managing teams, creating projects, and viewing reports are all quick and easy. A user is never more than two clicks away from any functionality.

Efficient tracking

By providing up-to-date information on how much actual effort is being expended across activities, projects, and teams, Projectory lets you measure the reality of your development costs against the “best case scenarios” provided by project planning software. This means that you can react to change rapidly– saving time, effort, and maybe even your job.

Flexible workflow

Use the default user group settings to manage access to functionality, or define new user groups to match the roles and responsibilities in your software development organization.

The key features of this development framework include:

- Practical Object-Oriented design that isn’t overly strict, needlessly complex, or focused on trying to be like Java.

- Representational State Transfer (REST) is a core part of the Alloy module architecture, and is built-in and accounted for from the beginning, not bolted-on as an afterthought.

- Coding simplicity and flexibility. Code flow is easier to follow, understand, and manipulate.

- No configuration or setup: Works out-of-the-box with no initial configuration or command-line setup required. Drag and drop files or upload directly to your web server.

- Serve your app from a root domain, subdomain, or a subfolder as many levels deeps as you like.

The goal of the StarUML project is to build a software modeling tool and also platform that is a compelling replacement of commercial UML tools such as Rational Rose, Together and so on.

StarUML is mostly written in Delphi. However, StarUML is a multi-lingual project and not tied to a specific programming language, so any programming languages can be used to develop it. (for example, C/C++, Java, Visual Basic, Delphi, JScript, VBScript, C#, VB.NET, …)

Gosu offers easy object-oriented interfaces to access common resources:

- Hardware-accelerated 2D graphics and text.
- Sound samples and music in various formats.
- Keyboard, mouse and gamepad input.

The library also offers extensive additional functionality including networking, advanced color operations, mathematical functions, locale operations and more.
As a game development library, it’s completely adapted to the classic game structure, featuring separated steps for processing logic, user input, and screen drawing.

The Windmill Test Frameworki includes the following features:

- Cross-browser test recorder: record, edit, playback and interact with your tests from one simple interface. Also checkout the DOM Explorer, Assertion Explorer and fully integrated Firebug-Lite.

- Interactive service shell: interact with the browser and the windmill service from a python shell, install ipython and automatically get an even more usable shell.

- Malleable proxy API: define rules for the Windmill proxy to follow, block those ad services or see what happens if your static content server goes down!

- JavaScript test integration: run your tests faster, write them in JavaScript! Also provides the complete set of JSUnit functions.

Windmill Controller: click, type, sleep, assert, pretty much anything you can think of doing to your web page is available as a windmill controller method.

Key software features include:

- Use it to easily paste/drag anything from your clipboard history.
- Assign global hot keys for access.
- Search your clipboard history.
- Multi user support.
- Simple install/update wizard.

Cassandra is an open source distributed database management system. Led by the Apache Software Foundation it was designed to handle very large amounts of data spread out across many commodity servers while providing a highly available service with no single point of failure.

It is a NoSQL solution that was initially developed by Facebook and powers their Inbox Search feature. Cassandra provides a structured key-value store with eventual consistency. Keys map to multiple values, which are grouped into column families. The column families are fixed when a Cassandra database is created, but columns can be added to a family at any time.

Key features of the system include:

- Decentralized: every node in the cluster is identical. There is no single point of failure.

- Fault-tolerant: data is automatically replicated to multiple nodes for fault-tolerance. Replication across multiple data centers is supported. Failed nodes can be replaced with no downtime.

- Tunable consistency: writes and reads offer a tunable ConsistencyLevel, all the way from “writes never fail” to “block for all replicas to be readable,” with the quorum level in the middle.

- Elasticity: Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications.

Further Info & Reading

For a more in-depth analysis and practical guide to Cassandra take a look at Eben Hewitt’s Cassandra: The Definitive Guide.

Alternatively, Beautiful Data by Toby Segaran and Jeff Hammerbacher provides an excellent overview of working with data from the perspective of 39 contributors working on projects ranging from the Mars lander to a Radiohead video. The book also includes a section on Cassandra.

Key features include:

- Advanced work with CSS
- Setting indentation (margins, paddings) for images and table cells (seperate for each direction)
- Controlling border properties (width, style, color) with convenient dialogs
- Writing element properties as CSS-style always when possible
- Interface appearance is configured from one CSS file
- The editor can be easily localized into any language. Currently available in English (default), Russian, German and Ukrainian languages

Key features include:
