Industria is a collection of portable R6RS Scheme libraries for cryptography (AES, DES, Blowfish, HMAC, MD5, SHA-1, SHA-2, RSA, DSA, etc.), zip/gzip/zlib decompression, disassembly of amd64 machine code, Off-The-Record messaging, bytevector pack/unpack syntax, TLS connections via custom binary ports, and more.
The Open Game Libraries is a collection of separately usable C++ libraries for creating games. It provides OpenGL window management, zip file management, OpenAL audio management, a developer console window, input management, bitmapped fonts with Unicode and kerning support, image loading and saving, model loading and importing, and generic classes and objects for game development such as math and text processing.
Thumbnailator is a thumbnail generation library with a fluent interface for Java. It simplifies the process of producing thumbnails from existing image files and image objects by providing an API which allows for fine tuning of thumbnail generation, while keeping the amount of code that needs to be written to a minimum.
Components 4 Java is a development tool for Java. It provides a framework to organize and separate different parts of code, and fills the gap between the class level and the library level as provided by the Java SE architecture. Additionally, you can organize your classes in well-separated and loosely coupled components. Those can be stuck together graphically into larger compositions. Finally, components and compositions will be distributed among Java archives as specified in assemblies.
GRAL is a library for creating high quality plots and charts in Java. Many plot types are available like scatter plot, bubble plots, line plots, area plots, pie charts, and bar charts. Additionally, GRAL can exchange and process data (smoothing), and various plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.
AppLogger is a library that allows an application programmer to provide run-time customizable output from an application. It includes a function, applogger_log(), with calling semantics analogous to the standard C library's printf(), but with extra arguments to specify a classification for the output message. Calls to applogger_log() thus specify the classification and text of a message; calls to other functions in the AppLogger library determine the real-time policy applogger_log() applies to messages of a given classification: print to file, send over a network socket, ignore the message, etc. In short, AppLogger allows for the separation of message content and message output policy in an application.
