ArduinoPulseGenerator is a simple program for generating pulse sequences using an Arduino. There is an associated GUI that runs on the local computer, or you can simply connect to the Arduino with a serial console (9600 baud) and send it commands. This code has been tested on the ArduinoMega 2560 (timing accuracy ~ ±200 μs) and Arduino Due (timing accuracy ~ ±35 μs); it may work on other Arduino boards.
wave-player is a remotely-controllable music player (frontend) connecting via HTTP calls to a music database (backend). It allows music to be controlled and streamed via HTTP so you can hear your music at work or anywhere else. The frontend is based on QT4 and the backend uses via Perl/MySQL. The API is open and REST-based.
Hypercube is a tool for visualizing DOT (graphviz), GML, GraphML, GXL and simple text-based graph representations as SVG and EPS images. It comes with a Qt-based GUI application and a Qt-independent commandline tool. It uses a simulated annealing algorithm to lay out the graph, which can be easily parameterized to achieve the desired look. The main development goals are portability and easy usage rather than high performance and complexity.
The YB.ORM library aims to simplify writing C++ code that has to deal with SQL databases. The goal is to provide a convenient interface like SQLAlchemy (Python) or Hibernate (Java). The library itself is cross-platform and supports a variety of SQL dialects: SQLite3, MySQL, Postgres, Oracle, and Firebird. Integration with Boost, Qt4, and wxWidgets is built-in. In a typical usage scenario, you would describe your database schema and table relationships in a simple XML-based format, generate SQL code to populate database schema with tables, generate C++ classes, add application-specific logic to the classes, and use these classes in cooperation with the Session object to query objects from the database, create new or modify/delete existing objects, or link and unlink objects using relations. Simple serialization to XML is supported along with connection pooling.
Fish Sync is a file syncing application. It can transfer multiple folders between multiple machines, keeping these folders synchronized. The Fish package does not need to be available on each machine in the group, only on the machine initiating the synchronization. The Fish program is separated into two pieces, one which does the work in the background, and the other a frontend configuration tool. This separation allows the Fish service to be run on servers where a GUI interface is not desired.
