Skeema is a tool for managing MySQL tables and schema changes in a declarative fashion using pure SQL. It provides a CLI tool allowing you to: * Export CREATE TABLE statements to the filesystem, for tracking in a repo (git, hg, svn, etc) * Diff changes in the schema repo against live DBs to automatically generate DDL * Manage multiple environments (e.g. dev, staging, prod) and keep them in sync with ease * Configure use of online schema change tools, such as pt-online-schema-change, for performing ALTERs * Apply configurable linter rules to proactively catch schema design problems and enforce company policies Skeema supports a pull-request-based workflow for schema change submission, review, and execution. This permits your team to manage schema changes in exactly the same way as you manage code changes.

SIP is a collection of tools that makes it very easy to create Python bindings for C and C++ libraries.

Siconos is an open-source scientific software primarily targeted at modeling and simulating nonsmooth dynamical systems in C++ and in Python: * Mechanical systems (rigid or solid) with unilateral contact and Coulomb friction and impact (nonsmooth mechanics, contact dynamics, multibody systems dynamics or granular materials). * Switched Electrical Circuit such as electrical circuits with ideal and piecewise linear components: power converter, rectifier, Phase-Locked Loop (PLL) or Analog-to-Digital converter. * Sliding mode control systems. * Biology (Gene regulatory network). Other applications are found in Systems and Control (hybrid systems, differential inclusions, optimal control with state constraints), Optimization (Complementarity systems and Variational inequalities), Fluid Mechanics, and Computer Graphics.

OpenVDB is an open source C++ library comprising a novel hierarchical data structure and a suite of tools for the efficient storage and manipulation of sparse volumetric data discretized on three-dimensional grids. It is developed and maintained by DreamWorks Animation for use in volumetric applications typically encountered in feature film production.
