Apache Hadoop
[25 users on Ohloh]
Hadoop is a framework for running applications on large clusters of commodity hardware. The Hadoop framework transparently provides applications both reliability and data motion. Hadoop implements a computational paradigm named map/reduce, where the application is divided into many small fragments of work, each of which may be executed or reexecuted on any node in the cluster. In addition, it provides a distributed file system that stores data on the compute nodes, providing very high aggregate ...
Apache Camel
[20 users on Ohloh]
Apache Camel is a powerful rule based integration framework which provides a POJO based implementation of the Enterprise Integration Patterns using an extremely powerful fluent API (or declarative Java Domain Specific Language) to configure routing and mediation rules. The Domain Specific Language means that Apache Camel can support type-safe smart completion of routing rules in your IDE using regular Java code without huge amounts of XML configuration files; though Xml Configuration inside Spr...

Tags: control .net sourcegrid grid
SourceGrid is a .NET Windows Forms grid control written entirely in C# with managed code. SourceGrid can be used to visualize or to change data in a table format.
SourceGrid con be used bound to a data source (typically a DataView) or creating each cell directly.
SourceGrid use only managed code (without API or Interop) and can be used with any .NET 2 compatible environments.
Inferno Distributed Operating System
[5 users on Ohloh]
Inferno® is a distributed operating system, originally developed at Bell Labs, but now developed and maintained by Vita Nuova® as Free Software. Applications written in Inferno's concurrent programming language, Limbo, are compiled to its portable virtual machine code (Dis), to run anywhere on a network in the portable environment that Inferno provides. Unusually, that environment looks and acts like a complete operating system.

The use of a high-level language and virtual machine is sensi...
