Minix editline is the line editing library from Minix, originally created by Simmule R. Turner and Rich $alz in 1992. It can be linked into almost any program to provide command-line editing and history. The editline library is call-compatible with the FSF readline library, but is a fraction of the size and offers fewer features. It is distributed under a "C News-like" copyright; see the file LICENSE for details.
Zynaptic Reaction is a flexible asynchronous programming framework for Java which may be used to implement complex event-driven applications. It is heavily influenced by the Twisted programming framework developed by TwistedMatrix Labs for the Python programming language. The focus of the Reaction library is on the concurrency and callback model and as such it is application neutral. It can be used to manage lots of concurrent I/O or to farm out compute intensive tasks to multicore processors. As well as being usable as a basic Java library, Reaction can also run as an independent OSGi service and integrate into any GUI framework you choose.
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.
metagloss is an annotation-centric Android library for reducing boilerplate code. Relying on run-time parsing and compile-time code generation, metagloss provides facilities for mapping XML and databases to data objects, dealing with preference screens and working with DB queries.
