Tree Layout Helper is a .NET/Mono library that provides some utilities for handling tree structures. Most importantly, it supports the display of tree structures as two-dimensional graphics. By using ready-made interfaces, you can specify the size of your nodes, and the Tree Layout Helper library will take care of placing those nodes appropriately.
OpenSimulator is a multi-platform, multi-user 3D distributed virtual environment platform. Out of the box, it can be used to simulate virtual environments similar to that of Second Life. These can be used as social virtual worlds or for specific applications such as education, training, and visualization. Access is via the regular Second Life open-source viewer or via third-party clients. There are a number of private and public deployments of OpenSimulator, including OSgrid, which has over 8000 regions hosted by independent individuals and organizations spread over the Internet.
ZixFS is a simple embedded file storage based on a Zip file structure. It has been developed as an alternative to GridFS, but is still not on par with it. The main objective is to provide a powerful filesystem under a Windows 32-bit environment, with the capability of handling terabytes of data, which is not offered by GridFS. The original ZipStorer class library was developed Jaime Olivares.
DotNetZip is a zip library for .NET and Silverlight. Using this library, you can build .NET or Silverlight applications that create, view, update, or unpack ZIP archives. DotNetZip also includes a ZLIB library and a BZip2 library. It is all managed code. Compact Framework versions of the libraries are included as well. The ZIP library supports WinZip AES encryption, regular PKZip encryption, Zip64, Unicode filenames, and many other ZIP features.
VoltDB is a blazingly fast relational database system. It is specifically designed to run on modern scale-out architectures: fast, inexpensive servers connected via high-speed data networks. It is aimed at a new generation of database applications - real-time feeds, sensor-driven data streams, micro-transactions, low-latency trading systems - requiring database throughput that can reach millions of operations per second. What’s more, the applications that use this data must scale on demand, provide flawless fault tolerance, and enable real-time visibility into the data that drives business value. It includes client application drivers for applications written in Java, C++, C#, PHP, and Python. VoltDB community members have also authored client libraries for Erlang, Ruby and Node.js. There are streaming export capabilities for leading analytic database environments, including Apache Hadoop.
