tadedon is a set of utilities that form a foundation for applications written with one of the many Java frameworks, such as GWT, GIN, Guice, Google App Engine, commons-configuration, and many others. It lets you specify the default configuration of your application and upgrade it automatically on each new release. It can redirect all java.util.logging to slf4j and easily configure logback. It can bind application configuration in a Guice module. It supports @PostConstruct and @PreDestroy annotations (JSR 250) in Guice applications. It lets you annotate your methods with @Transactional annotation. It supports Guice injector stage in your Web application. It lets you test your Guice managed servlets and filters without needing a real servlet container. It lets you use Guice Matchers for matching super class, interface, and type literal annotations. It can inject event bus to your GWT applications with the help of GIN.
IKNetworkActivityManager is a Cocoa class that simplifies work with UIApplication network activity indicator. It turns your networkActivityIndicatorVisible = YES/NO code to add/removeNetworkUser:, so you don't need to remember objects that can use network anymore. A demonstration App is available.
junixsocket is a Java/JNI library that allows the use of Unix Domain Sockets (AF_UNIX sockets) from Java. In contrast to other implementations, junixsocket extends the Java Sockets API (java.net.Socket, java.net.SocketAddress, etc.) and even supports RMI over AF_UNIX. It is also possible to use it in conjunction with Connector/J to connect to a local MySQL server via Unix domain sockets.
NSFFT is yet another FFT library for performing 1-dimensional fast Fourier transforms. It is a simple, small, and portable library, and it is efficient since it can utilize SIMD instruction sets in modern processors. It performs multiple transforms simultaneously, and thus it is especially suitable for digital signal processing.
Perf4CDI is an add-on package for implementations of CDI (Contexts and Dependency Injection for the Java EE platform, also known as JSR-299) providing convenient integration with Perf4j, a performance monitoring library for Java applications. For basic usage, it's enough to annotate the profiling method in CDI-based applications. Many settings can be customized.
The STX ExecPipe library provides a convenient C++ interface to execute child programs connected via pipes. It is a front-end to the system calls fork(), pipe(), select(), and execv() and hides all the complexity of these low-level functions. It allows a program to build a sequence of connected children programs with the input and output of the pipe sequence redirected to a file, string, or file descriptor. The library also allows custom asynchronous data processing classes to be inserted into the pipe or placed at the source or sink of the sequence.
