linuxptp is an implementation of the Precision Time Protocol (PTP) according to IEEE standard 1588 for Linux. The dual design goals are to provide a robust implementation of the standard and to use the most relevant and modern Application Programming Interfaces (API) offered by the Linux kernel. Supporting legacy APIs and other platforms is not a goal.
nut is nutrition software to record what you eat and analyze your meals for nutrient composition. The database included is the latest USDA Nutrient Database for Standard Reference. This database contains values for vitamins, minerals, fats, calories, protein, carbohydrates, fiber, etc., and includes the essential polyunsaturated fats, Omega-3 and Omega-6. Nutrient levels are expressed as a percentage of the Daily Value, the familiar standard of food labeling in the United States, but also can be fully customized. Foods can be added from recipes or food labels, and nutrient intake can be graphed. The program is completely menu-driven and there are no commands to learn.
Data2l is a language neutral, platform neutral way for describing large sets of proprietary binary data. An example of this kind of data is car navigation data, which is about 1GB to 15GB in a typical embedded navigation. With Data2l you can easily describe almost any binary data format using primitive description blocks like basic type, array, structure, or alternative and using a functional dependency description language. Using such a description, one can generate source code optimized for certain tasks, like a lightweight data reading layer, fast querying code, or code suitable for data generation and transformation.
The Blender-Mathutils module originated from Blender, where it has been used for some years in production as a utility module for use in areas including animation, games, and mesh manipulation. This differs from 'numpy' in that it is computer graphics focused, combining Matrix and Vector types with rotation classes, which is very useful for use with animation or anywhere Euler and Quaternion values are frequently used. This project is mainly a build system around the actively maintained mathutils code in Blender to allow non-Blender related projects to make use of it. A link to the Blender repository is used so that the source never gets out of sync.
hexter is a software synthesizer that models the sound generation of a Yamaha DX7 synthesizer. It can easily load most DX7 patch bank files, edit those patches via a built-in editor or MIDI sys-ex messages, and recreate the sound of the DX7 with greater accuracy than any previous open source emulation (that the author is aware of). It operates as a plugin for the DSSI Soft Synth Interface.
