QuantComponents is a framework for financial time-series analysis and algorithmic trading, based on Java and OSGi, with an Eclipse front-end. It is highly modular: usable as a plain Java API, OSGi components, or integrated into Eclipse. It works standalone or with a client-server architecture, depending on performance and reliability needs, and is integrated with Interactive Brokers through the IB Java API. Its generic broker API means that it can easily be extended to work with other brokers. A backtesting facility and an extensible SWT charting library are provided.
protobuf-dt is Google’s Eclipse-based editor for protocol buffers. It provides all the features you’d expect from an Eclipse editor (syntax highlighting, outline view, content assist, etc.) plus some protocol buffer-specific features, such as "Open Declaration" (hyperlinking) support, including imported .proto files, configurable integration with protoc, and automatic removal of trailing whitespace.
kbd-cheatsheet is a small application that generates a list of Eclipse keyboard shortcuts from Eclipse's CSV export function. The shortcuts are grouped, sorted, and arranged according to user defined settings. Since the basis for the sheet is your current Eclipse installation, everybody can create their own personalised version.
