The cptutils package contains a number of utilities for the manipulation of color gradients; mainly for translating between different formats. Formats supported include ggr (GIMP gradient), cpt (GMT color palette table), avl (Arcview Legend), the PaintShop Pro and Photoshop formats, SVG, and CSS3.
Freeverb3 is a signal processing library. It includes many types of audio processing effects and signal generators including a linear feedback shift register (LFSR) maximum length sequence (MLS) generator, multiple types of high quality mono+stereo reverb effects, a multi slot impulse response processor, multiband hardknee+softknee compressor and limiter, a stereo enhancer, a limiter, and many types of infinite impulse respose (IIR) and finite impulse response (FIR) filters. Also available is Freeverb3VST, a VST effects plugins package based on the Freeverb3 library.
openQRM is a data-center management and cloud computing platform. Its fully pluggable architecture focuses on automatic, rapid, and appliance-based deployment, monitoring, high-availability, cloud computing, and especially on supporting multiple virtualization technologies. openQRM is a single-management console for a complete IT infrastructure and provides a well-defined API which can be used to integrate third-party tools as additional plugins.
Fityk is nonlinear curve-fitting and data analysis software. It allows data visualization, separation of overlapping peaks, and least squares fitting using standard Levenberg-Marquardt algorithm, a genetic algorithm, or Nelder-Mead simplex method. It knows about many functions (mostly bell-shaped, like Gaussian, Loretzian, Pearson 7, Voigt, Pseudo-Voigt, and Doniach-Sunjic) and user-defined functions can be easily added. It also enables background subtracting, data calibration, and task automation with a simple script language. It is mainly used to analyze powder diffraction patterns, chromatography, photoluminescence, infrared, and Raman spectroscopy, but it can be used to fit analytical functions to any kind of data.
Thinknowlogy is grammar-based software, designed to utilize the Natural Laws of Intelligence in grammar, in order to create intelligence through natural language in software. This is demonstrated by programming in natural language, reasoning in natural language and drawing conclusions (more detailed than scientific solutions), making assumptions (with self-adjusting level of uncertainty), asking questions (about gaps in the knowledge), and detecting conflicts in the knowledge. It builds semantics autonomously (with no vocabularies or words lists), detecting some cases of semantic ambiguity. It is multi-grammar, proving that Natural Laws of Intelligence are universal.
Makeflow is a workflow engine for executing large complex applications on clusters, clouds, and grids. It can be used to drive several different distributed computing systems, including Condor, SGE, and the included Work Queue system. It does not require a distributed filesystem, so you can use it to harness whatever collection of machines you have available. It is typically used for scaling up data-intensive scientific applications to hundreds or thousands of cores.
pyPEG is a quick and easy solution for creating a parser in Python programs. pyPEG uses a PEG language in Python data structures to parse, so it can be used dynamically to parse nearly every context free language. The output is a plain Python data structure called pyAST, or, as an alternative, XML.
amforth is an extendible command interpreter for the Atmel AVR ATmega microcontroller family. It has a turnkey feature for embedded use as well. It does not depend on a host application. The command language is an almost compatible ANS94 forth with extensions. It needs less than 8KB code memory for the base system. It is written in assembly language and forth itself.
