Google Web Toolkit (GWT) allows developers to create Ajax applications in the Java programming language.

Google's Ajax APIs[3] let a developer implement rich, dynamic websites entirely in JavaScript and HTML.

A developer can create a map to a site, a dynamic search box, or download feeds with just a few lines of javascript.

The AdSense and AdWords APIs, based on the SOAP data exchange standard, allow developers to integrate their own applications with these Google services.

In a subsequent deployment step, the GWT compiler translates a working Java application into equivalent JavaScript that programmatically manipulates a web browser's HTML DOM using DHTML techniques.

GWT emphasizes reusable, efficient solutions to recurring Ajax challenges, namely asynchronous remote procedure calls, history management, bookmarking, and cross-browser portability.

Google OR-Tools[8] provides programming language wrappers for operations research tools such as optimisation and constraint solving.

A GDG can take many forms—from just a few people getting together, to large gatherings with demos and tech talks, to events like code sprints and hackathons.
