Google Developers

Google Developers (previously Google Code) is Google's site for software development tools, application programming interfaces (APIs), and technical resources. The site contains documentation on using Google developer tools and APIs—including discussion groups and blogs for developers using Google's developer products.

There are APIs offered for almost all of Google's popular consumer products, like Google Maps, YouTube, Google Apps, and others.

The site also features a variety of developer products and tools built specifically for developers. Google App Engine is a hosting service for web apps. Project Hosting gives users version control for open source code. Google Web Toolkit (GWT) allows developers to create Ajax applications in the Java programming language.

The site contains reference information for community based developer products that Google is involved with like Android from the Open Handset Alliance and OpenSocial from the OpenSocial Foundation.

Google APIs

Google offers a variety of APIs, mostly web APIs for web developers. The APIs are based on popular Google consumer products, including Google Maps, Google Earth, AdSense, Adwords, Google Apps and YouTube.[1]

Google Data APIs

The Google Data APIs[2] allow programmers to create applications that read and write data from Google services. Currently, these include APIs for Google Apps, Google Analytics, Blogger, Google Base, Google Book Search, Google Calendar, Google Code Search, Google Earth, Google Spreadsheets, Google Notebook, and Picasa Web Albums.

Ajax APIs

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.

Ads APIs

The AdSense and AdWords APIs, based on the SOAP data exchange standard, allow developers to integrate their own applications with these Google services. The AdSense API allows owners of websites and blogs to manage AdSense sign-up, content and reporting, while the AdWords API gives AdWords customers programmatic access to their AdWords accounts and campaigns.

Developer tools and open-source projects

App Engine

Google App Engine lets developers run web applications on Google's infrastructure. Google App Engine supports apps written in several programming languages. With App Engine's Java runtime environment, one can build their app using standard Java technologies, including the JVM, Java servlets, and the Java programming language—or any other language using a JVM-based interpreter or compiler, such as JavaScript or Ruby. App Engine also features a dedicated Python runtime environment, which includes a fast Python interpreter and the Python standard library.

Google Plugin for Eclipse

Google Plugin for Eclipse (GPE) is a set of software development tools that enables Java developers to design, build, optimize, and deploy cloud computing applications. GPE assists developers in creating complex user interfaces, generating Ajax code using the Google Web Toolkit, optimizing performance with Speed Tracer,[4] and deploying applications to Google App Engine. GPE installs into the Eclipse integrated development environment (IDE) using the extensible plugin system.[5] GPE is available under the Google terms of service license.[6]

Google Web Toolkit

The Google Web Toolkit (GWT) is an open source toolkit allowing developers to create Ajax applications in the Java programming language.[7] GWT supports rapid client–server development and debugging in any Java IDE. 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. It is released under the Apache License version 2.0.

OR Tools

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

Google Code

Google previously ran a project hosting service called Google Code[9] that provided revision control offering Subversion, Mercurial[10] and Git[11] (transparently implemented using Bigtable as storage), an issue tracker, and a wiki for documentation. The service was available and free for all OSI-approved Open Source projects (as of 2010, it was strongly recommended but no longer required to use one of the nine well-known open source licenses: Apache, Artistic, BSD, GPLv2, GPLv3, LGPL, MIT, MPL and EPL). The site limited the number of projects one person could have to 25.[12] Additionally, there was a limit on the number of projects that could be created in one day, a 200 MB default upload file size limit, which could be raised, and a 5 GB per-project total size limit.[13] The service provided a file download feature, but on May 2013 the creation of new downloads was disabled, with plans to disable it altogether on January 14, 2014.[14] In March 2015, Google announced that it would be closing down Google Code on January 15, 2016.[15] All projects on the site entered read-only mode on August 24, 2015,[16] with the exception of certain Google-owned projects including Android and Chrome.[15]

Residents of countries on the United States Office of Foreign Assets Control sanction list, including Cuba, Iran, North Korea, Sudan and Syria, were prohibited from posting to or accessing Google Code.[17]


Gears was beta software offered by Google to enable offline access to services that normally only work online. It installed a database engine, based on SQLite, on the client system to cache data locally. Gears-enabled pages used data from this local cache rather than from the online service. Using Gears, a web application may periodically synchronize the data in the local cache with the online service. If a network connection is not available, the synchronization is deferred until a network connection is established. Thus Gears enabled web applications to work even though access to the network service is not present. Google announced the end of Gears development on March 11, 2011, citing a shift of focus from Gears to HTML5.[18]

Google developer events

Google Developer Groups

Google Developer Groups[19] (GDGs) are for developers who are interested in Google's developer technology. 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. As of March 2015, there are currently 600+ GDGs worldwide.

Poly is a website created by Google for users to browse, distribute, and download 3D objects. It is intended to allow creators to easily share and access 3D objects. It features a free library containing thousands of 3D objects for use in virtual reality and augmented reality applications.

Progressive web applications

Progressive web applications (PWAs) are web applications that load like regular web pages or websites but can offer the user functionality such as working offline, push notifications, and device hardware access traditionally available only to native applications. PWAs combine the flexibility of the web with the experience of a native application.

Protocol Buffers

Protocol Buffers are a method of serializing structured data.

It is useful in developing programs to communicate with each other over a wire or for storing data. The method involves an interface description language that describes the structure of some data and a program that generates source code from that description for generating or parsing a stream of bytes that represents the structured data.

Google developed Protocol Buffers for use internally and has provided a code generator for multiple languages under an open source license (see below).

The design goals for Protocol Buffers emphasized simplicity and performance. In particular, it was designed to be smaller and faster than XML.Protocol Buffers is widely used at Google for storing and interchanging all kinds of structured information. The method serves as a basis for a custom remote procedure call (RPC) system that is used for nearly all inter-machine communication at Google.Protocol Buffers are similar to the Apache Thrift (used by Facebook) or Microsoft Bond protocols, offering as well a concrete RPC protocol stack to use for defined services called gRPC.A software developer defines data structures (called messages) and services in a proto definition file (.proto) and compiles it with protoc. This compilation generates code that can be invoked by a sender or recipient of these data structures. For example, example.proto will produce and example.pb.h, which will define C++ classes for each message and service that example.proto defines.

Canonically, messages are serialized into a binary wire format which is compact, forward- and backward-compatible, but not self-describing (that is, there is no way to tell the names, meaning, or full datatypes of fields without an external specification). There is no defined way to include or refer to such an external specification (schema) within a Protocol Buffers file. The officially supported implementation includes an ASCII serialization format, but this format—though self-describing—loses the forward- and backward-compatibility behavior, and is thus not a good choice for applications other than debugging.

Though the primary purpose of Protocol Buffers is to facilitate network communication, its simplicity and speed make Protocol Buffers an alternative to data-centric C++ classes and structs, especially where interoperability with other languages or systems might be needed in the future.

TRT World

TRT World is a Turkish international news channel broadcast 24-hours per day in English. The news channel is based in Istanbul. It provides worldwide news and current affairs with a pronounced emphasis on news relating to Turkey and Western Asia.

It is aimed at a worldwide audience and is broadcast via satellite, cable operators and across digital platforms. In addition to its Istanbul headquarters, TRT World has broadcast centres in Washington D.C., London, and Singapore.

TRT World is part of Turkey's public broadcaster, the Turkish Radio and Television Corporation, and is a member of the Association for International Broadcasting.

Web development tools

Web development tools (often called devtools) allow web developers to test and debug their code. They are different from website builders and integrated development environments (IDEs) in that they do not assist in the direct creation of a webpage, rather they are tools used for testing the user interface of a website or web application.

Web development tools come as browser add-ons or built-in features in web browsers. Most popular web browsers, such as Google Chrome, Firefox, Internet Explorer, Safari and Opera, have built-in tools to help web developers, and many additional add-ons can be found in their respective plugin download centers.

Web development tools allow developers to work with a variety of web technologies, including HTML, CSS, the DOM, JavaScript, and other components that are handled by the web browser. Due to increasing demand from web browsers to do more, popular web browsers have included more features geared for developers.
