peak-o-mat is a data analysis and curve fitting program. It was designed to fit spectroscopic data but should be suited for any other fitting task. It allows for clearing, transforming, fitting, calibrating, etc. of spectra with few mouse clicks. It can be scripted using the Python language and can be extended by writing modules.
PricesPaidGUI is a visualization tool for transactional price data that uses SOLR to provide full-text searching. It currently supports two formats, and its architecture allows for extending to more. It is intended to be used by government buyers researching actual prices paid in order to lower the price the Federal Government pays for goods and services.
DAE Tools is cross-platform equation-oriented process modelling, simulation, and optimization software. Various types of processes (lumped or distributed, steady-state or dynamic) can be modelled and optimized. They may range from very simple to those which require complex operating procedures. Equations can be ordinary or discontinuous, where discontinuities are automatically handled by the framework. Model reports containing all information about a model can be exported in XML MathML format, automatically creating high-quality documentation. The simulation results can be visualized, plotted, and/or exported into various formats.
Bokken is a GUI for the Pyew and Radare2 projects. It provides an interface to almost all the features of Pyew, and many in radare2. It's intended to be a multi-architecture disassembler and binary analysis tool, and maybe some day an alternative for commercial alternatives as IDA Pro. Currently, Bokken is neither a hexadecimal editor nor a full featured disassembler, so it should not be used for deep code analysis or for modifying files.
PyGUI is a GUI API which is designed specifically for Python, taking advantage of Python's unique language features and working smoothly with Python's data types on the three major platforms (Unix, Macintosh, and Windows) that are small and lightweight, interposing as little code as possible between the Python application and the platform's underlying GUI facilities, and not bloating the Python installations or applications which use them.
