Web App to control Bticino MyHome using OpenWebNet
Grasshopper is an open source and free (speech & beer) responsive-design web application to control Bticino MyHome. VALUES: Use any device Since Grasshopper is a browser-based application, you can use a browser on any device to access Grasshopper. Thanks to its responsive-design support, the Grasshopper interface will adapt to the screen-size of your device. Choice of server-platform Grasshopper is a web application that can run from different web servers. The Grasshopper appliance runs on DietPi with Lesp (Nginx+SQLite+PHP). The Grasshopper application has been tested on Lesp and LAMP+SQLite. (Both documented in following chapters). The only requirement is that SQLite is used as a database. You can read more about this in following chapters. Choice of MyHome Gateway Grasshopper can communicate not only through the official Bticino Gateways (eg. MH20x / F452 / F454) but also network-connected touchscreens can be used (eg. 3,5" / 10")

Additional support for SVG files over AGG or Cairo library. Also irrlicht_c library give access to Irrlicht functional from other programming languages: ASM (FASM), C (TinyC), Basic (FreeBASIC, thinBasic, OxygenBasic), Pascal, Gentee, AutoIt and game frameworks like GameMaker or Blitz.
Management of source code quality is possible.
Metrix++ is an extendable tool to collect and analyse code metrics. - Multiple languages supported - Multiple metrics available - Configurable. Every metric has got 'turn-on' and other configuration options. There are no predefined thresholds for metrics or rules. You can choose and configure any limit you want. - High-performance. Processes thousands of files per minutes. - Seamless application to legacy code due to embedded capability to differentiate new code, modified and legacy.

Assorted projects. General-purpose libraries for Python, C++, Scala, bash, and others. Meta-programming tools. System utilities. UI components. Web APIs. Configuration files. Benchmarks. Programming competition entries. And much more.
A designer’s program for describing parts of the building
Buildes is an integrated development environment that assists the user in creating building information. It reads a text (session) file from which it compiles the information. It then allows the user to browse, analyze and export the resulting building knowledge. The compilation system is written in pure Python. The building components created are rendered in PythonOCC. The GUI is written using PyQt.
Acoustic Simulation Library for Frequency and Time Domain Simulations.
ART is a flexible simulation framework for wind instruments. It includes a growing library of modelling elements. So far bore discontinuities, branches, tone holes, cylindrical and conical tubes, Bessel horns and bent tubes are available for frequency domain modelling. In the time domain generic bidirectional propagation elements, scattering elements, fractional delays, convolution with reflection functions and general z-domain networks are available and can be described using MuParserX expressions. Cylindrical and conical ducts can also be defined based on their geometry. Available models and their parameters can be enumerated and combined to form simulators for complex acoustical structures. Parameters can be specified symbolically by expressions containing other parameter values or global variables. Dependencies between parameters are resolved at run time. However, MuParserX expressions are compiled at design time. Zero-delay loops are detected and reported.
A SUpport MOdule manager for EPICS
sumo is a program to build consistent sets of EPICS support modules and use them in EPICS applications. EPICS is the Experimental Physics Industrial Control System. Some of the features are: - All module dependencies are held in a JSON dependency database. - The dependency database can be managed automatically with a version control system in order to keep it in sync on a number of build hosts. - In order to migrate your existing support module installation a scanner program creates a dependency database from existing support directories. - The program builds consistent sets of EPICS support modules. - The program fetches module source code from various sources, directories, tar files or version control systems (currently git,mercurial, darcs, subversion and cvs). - If a set of support modules is to be used in an application a RELEASE is generated.
Tools to train Image Operators automatically from a set of samples.
TRIOS - Training Image Operators from Samples is a set of tools to bring Image Processing closer to scientists in general. It is capable of estimating an operator between two images using only pairs of samples that contain an input image and the desired output. The operator is saved to a file and can be applied to any image.
Collaborative editor, requirements management tool and much more
ARREA (A Reasonable Requirements Engineering Application) is a simple yet powerful requirements management tool that uses arbitrary files to store information and Subversion to allow team collaboration. Its simple conventions make it suitable for much other purposes. In fact, for any document-oriented tasks focused on collaborative work and exhaustive change and traceability management. At its heart, ARREA provides a thin layer on top of SVN that allows it to be used as a powerful time-aware NoSQL database, accessible through an easy REST API.
