Huxley is a set of classes that makes it trivial to produce legitimate output for queries made by the prevailing standard of REST queries. Instead of writing a network API with many methods, being run over RPC, you instead write only a couple of methods that are accessed by HTTP GET requests. You then return the results (in either XML, JSON, or text) for processing. XML and JSON are chosen because of the ease by which they can be parsed by most languages. In this way, you open up the scope of your network services to many more people than would otherwise have access to it.
IIR is a C++ library that implements fast IIR filters: bandpass, bandstop, lowpass, and highpass. These can be designed using popular analogue filter functions such as Butterworth, Bessel, Chebyshev, Elliptic, Legendre, and pole placement. Creation of a complete filter requires only a single command and filtering is performed with a single function taking a sample and returning its result instantly. The library is template-based and avoids new/mallocs throughout. This library has been adapted form Vinnie Falco's original work and has been converted to run on Unix systems and turned into a realtime causal filter.
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.
JChartLib is a library for drawing beautiful charts. It supports linecharts and barcharts with colors, automatic axis numbering, and automatic styling depending on the number of values. Charts can be integrated into Java swing applications. Charts can be saved as jpg or png image files.
JHeatChart is a one class Java API for generating heat map charts that was created because very few charting APIs seem to contain the facility to create heat maps. It is not a full featured charting API and cannot be used to other charts. The generated charts are created as Java Image objects, which can be incorporated into a GUI or saved to a file.
JPCX is a Java package that provides a way to encode and decode PCX image data. Its main features are fast reading of meta-data by reading minimal data, the ability to read from any InputStream one time or any FileInputStream many times, support for both 8-bit indexed color and 24-bit true-color images, support for encoding and decoding both RLE and uncompressed, and the ability to encode and decode to different target streams easily.
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.
