Freedomotic is an open, flexible, scalable, mashup-oriented software system which can interact with well-known standard building automation protocols and with "do-it-yourself" solutions. It treats the Web, social networks, and frontends just like any other sensor or actuator in your automation system. For example, you can tweet your washing machine to start the washing cycle. Freedomotic leverages modern enterprise integration patterns and distributed computing architectures, along with cross-language APIs for extensions.
Midao is a framework that was created to simplify development with JDBC. It shields developers from the nuances of vendor JDBC implementations and provides standard JDBC boilerplate code. It is flexible, customizable, and simple and intuitive to use, and provides a lot of functionality: transactions, metadata, type handling, profiling, input/output processing/converting, pooled datasource library support, named parameters, multiple vendor support out of the box, custom exception handling, and overrides. With a single Jar, it supports both JDBC 3.0 (Java 5) and JDBC 4.0 (Java 6). It is well tested, with over 500 unit and functional tests, and is also tested with the latest drivers for Derby, MySQL (MariaDB), PostgreSQL, Oracle, and Microsoft SQL.
