QuickImage is an open-source utility for adding drawings and graphs to your Web applications. It was designed primarily for use with the SteelBlue Application Server, but is general enough to be used in many programming environments. The QuickImage package contains both Java classes that can draw images on the client's browser and a C++ program that can draw images on the Web server. They both interpret the same set of graphics commands, and you only need one version to add drawings to your Web applications.
The Java Penrose Empires Package allows you to compute the empires (forced tiles) for an arbitrary initial patch of tiles. Tilings may be saved for later, and may be exported to PDF, EPS, or PNG. This software represents a new method of computing forced tiles. Rather than using a "growth" approach (where some tiles are randomly forced), this system only shows the forced tiles in the system, leaving all unforced areas blank.
The Beartronics J2ME Libraries are a collection of utilities and applications for programming in the Java MIDP and CLDC environment. They include a full cHTML browser, a fixed-point math library, 3D vector graphics and animation, and a small SVG-like vector shape viewer with compact binary shape file format.
lemontree provides a very fast Java class for the Walsh Hadamard transform (WHT) and O'Connor transform (OCT). You can regard the OCT as a black box which turns arbitrary numerical data into data with a Gaussian distribution. There are inverse transforms, also. It has many applications, such as Random Projections, Compressive Sensing, Neural Nets, and Genetic algorithms.
jIRCii is a cross platform Internet Relay Chat client. It is fully scriptable using a Perl-like language called sleep. The focus is to provide a console client experience with the advantages of a solid GUI. It includes DCC/CTCP support, the ability to connect to SSL servers, and over 65 built-in commands.
