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.
Apptools is a collection of programs for accessing Applix 1616/OS disk images. It is similar to 'mtools' and 'cpmtools' for MS-DOS and CP/M disks. The tools have been tested on Applix 1616/OS floppy disk images, but should work on hard disk images. The tools are limited to reading and only work with raw disk images. The collection includes programs for listing, copying, displaying, and reporting, and all tools allow recursive and wildcard operations.
PyMuTester is tool to facilitate Mutant Testing (a.k.a Mutant Analysis or Program Mutation) on software systems written in Python. Its main purpose is to assist you in improving your existing unit tests to cover missing checks and “loopholes” in your testing. It works by making small changes (technically known as mutants) to your Python application’s source code and re-running your unit tests over these mutated applications' source code. Since the mutants usually go against the specifications, your unit tests should fail in such tests. If the unit tests still pass, then that is an indication that your unit tests might have missed some checks.
