    Featureless Linux Library

    Featureless Linux Library

    Linux Library on top of Libc focusing on long term support.

    When computer power increases, programmers generally add more "features", thus making any performance gains in new hardware negligible. This project is an attempt to develop a library above libc that breaks out of this terrible loop.

    Temporal Inference Engine

    Temporal Inference Engine

    A real time inference engine for temporal logical specifications

    A real time inference engine for temporal logical specifications, which is able to acquire, process and generate any binary or real signal through POSIX IPC, files or UNIX sockets. Specifications of signals and dynamic systems are represented as special graphs and executed in real time, with a predictable sampling time of few milliseconds. Real time signal processing, dynamic system control, state machine modeling and logical property verification are some fields of application of this software. The accepted language provides timed logic and mathematical operators, conditional operators, interval operators, bounded quantifiers and parametrization of signals.

    Automalator

    State Dependency deconstructor and mapper for C source code.

    Flowcharts not telling you what you want to know about some C source code? Try a State Dependency map! Every C source file is an implemention of a state machine. Implicit in the definition of a state machine is a network of dependencies between the states. The Automalator * deconstructs the C code into the core state machine * collates the transactions into the dependency net * generates a diagram-format file with the states and dependencies as the nodes and edges. Pre-requisites * Perl - tested with versions 5.12.3, 5.14.2 and 5.20.2, Windows, Linux and MAC * Get the Automalator by downloading the zip, or checking out or exporting the SVN trunk * copy the source code of interest into "project.c" * windows - double-click "src2map.bat" * linux & MAC - navigate the command line to the "project" folder, then run "src2map.sh" * open "project.gml" file with diagramming software.

    ObjectBuilder2

    ObjectBuilder2

    C++ CASE tool, full life cycle code generator

    ObjectBuilder is a C++ code generation CASE tool (CASE, code generation, refactoring, documentation generation). It lets you create, manipulate and navigate classes, class relations, class members and class methods at a high level of abstraction. ObjectBuilder dramatically simplify work with C++ project architecture. I use it and think that tree OO interface targeted to C++ more fast and power than UML class diagrams. ObjectBuilder perfectly organize C++ header files with any level of complexity. Even if you use loop-references if OO hierarchy, you need include only one project-level header file. You can easy modify and refactore existing project with cut/copy/paste ANY object (from Method Argument to entire Project) within project and between ObjectBuilder projects. ObjectBuilder is not an IDE tool. It is portable two-way architect code-generation tool.
