Catharsis.NET.Domain is a .NET library which provides commonly used types of domain business entities such as articles, blogs, comments, downloads, and a FAQ to speed up the development of typical business applications. It includes domain entity types declared as partial classes (can be extended if necessary), a set of common domain-related interfaces, like INameable and ITaggable, and a set of extension methods for IEnumerable/IQueryable sets of domain entities.
Catharsis.NET.Commons is a library of extensions for many common .NET types. It can significantly speed up your daily .NET development tasks, relieving you of writing boilerplate code. It implements the popular fluent-kind interface approach and allows many tasks to be performed in a single line of code with joined method calls.
JS-Collider is an event-driven Java network NIO framework. It is designed to provide maximum performance and scalability for applications having not too many connections but significant amounts of network traffic (both incoming and outgoing). Performance and scalability are achieved via lock free algorithms and atomic states usage. It supports UDP (with multicast) as well. One of the implementation points is to avoid unsafe cheating; it should work the same way on all JVMs (Java 1.7). It supports shared memory IPC.
android-metadata is a utility library for Android designed to simplify reading metadata values from AndroidManifest.xml. It can quickly access metadata values from anywhere with a few lines of code, read individual metadata values into type-specific variables, and read one or more metadata values into annotated Java classes.
sqlpp11 is an embedded domain-specific language which allows programming SQL very naturally in modern C++. It also enables the compiler to detect syntax errors, type errors, name errors, and even some semantic errors before they ever hit unit tests or production. Queries can be constructed at compile time or run time, offering varying levels of safety and flexibility.
