John L. Hennessy
Before joining Google, he was an Associate Professor of Computer Science at University of California, Santa Barbara. He received a master's degree in computer science from ETH Zurich in 1988 and was awarded a Fulbright scholarship that same year. In 1994, he earned a Ph.D. from Stanford University, where his research focused on programming languages and their efficient implementation. Via a startup founded by Hölzle, David Griswold, and Lars Bak (see Strongtalk), that work then evolved into a high-performance Java VM named HotSpot, acquired by Sun's JavaSoft unit in 1997 and from there became Sun's premier JVM implementation.
He led the design of Google's very efficient data centers which are said to use less than half the power of a conventional data center. In 2014 he received The Economist's Innovation Award for his datacenter efficiency work. With Luiz Barroso, he wrote The Datacenter as a Computer: An Introduction to the Design of Warehouse-Scale Machines. In June 2007, he introduced the Climate Savers Computing Initiative together with Pat Gelsinger which aims to halve the power consumption of desktop computers and servers.
Also in 2007, he and Luiz Barroso wrote "The Case for Energy Proportional Computing" which argued that servers should be designed to use power in proportion to their current load, because they spend much of their time being only partially loaded. This paper is often credited for spurring CPU manufacturers to make their designs much more energy efficient. Today, energy proportional computing has become a standard goal for both server and mobile uses.
In 2011, Hölzle announced a shift in Google.org's alternative energy investment strategy, dropping development of "solar thermal" electricity (for example with BrightSource Energy) because ST was not keeping pace with the rapid price decline of another solar technology – photovoltaics.
In 2012, Hölzle introduced "the G-Scale Network" on which Google had begun managing its petabyte-scale internal data flow via OpenFlow, an open source software system jointly devised by scientists at Stanford and the UC Berkeley and promoted by the Open Networking Foundation. The internal data flow, or network, is distinct from the one that connects users to Google services (Search, Gmail, YouTube, etc.). In the process of describing the new network, Hölzle also confirmed more about Google's making of its own networking equipment like routers and switches for G-Scale; and said the company wanted, by being open about the changes, to "encourage the industry — hardware, software and ISP's — to look down this path and say, 'I can benefit from this.'" He said network utilization was nearing 100% of capacity, a dramatic efficiency improvement.
He is member of the National Academy of Engineering, and a Fellow of the Association for Computing Machinery (2009), the AAAS (2017), and the Swiss Academies of Arts and Sciences. He was 2009-2018 board member of the US World Wildlife Fund. He is member of the National Council of WWF-US.
The AI Challenge was an international artificial intelligence programming contest started by the University of Waterloo Computer Science Club.
Initially the contest was for University of Waterloo students only. In 2010, the contest gained sponsorship from Google and allowed it to extend to international students and the general public.Android Q

Chromebit allows adding a keyboard or mouse over Bluetooth or Wi-Fi. The device was announced in April 2015 and began shipping that November.GData
GData (Google Data Protocol) provides a simple protocol for reading and writing data on the Internet, designed by Google. GData combines common XML-based syndication formats (Atom and RSS) with a feed-publishing system based on the Atom Publishing Protocol, plus some extensions for handling queries. It relies on XML or JSON as a data format.
G Suite Marketplace (formerly Google Apps Marketplace) is a product of Google Inc. It is an online store for web applications that work with Google Apps (Gmail, Google Docs, Google Sites, Google Calendar, Google Contacts, etc.) and with third party software. Some Apps are free. Apps are based on Google APIs or on Google Apps Script.Google Behind the Screen
"Google: Behind the Screen" (Dutch: "Google: achter het scherm") is a 51-minute episode of the documentary television series Backlight about Google. The episode was first broadcast on 7 May 2006 by VPRO on Nederland 3. It was directed by IJsbrand van Veelen, produced by Nicoline Tania, and edited by Doke Romeijn and Frank Wiering.Google Business Groups

Google Forms is a survey administration app that is included in the Google Drive office suite along with Google Docs, Google Sheets, and Google Slides.
Forms features all of the collaboration and sharing features found in Docs, Sheets, and Slides.Google Guice
Google Guice (pronounced "juice") is an open-source software framework for the Java platform released by Google under the Apache License. It provides support for dependency injection using annotations to configure Java objects. Dependency injection is a design pattern whose core principle is to separate behavior from dependency resolution.
Guice allows implementation classes to be bound programmatically to an interface, then injected into constructors, methods or fields using an @Inject annotation. When more than one implementation of the same interface is needed, the user can create custom annotations that identify an implementation, then use that annotation when injecting it.
Being the first generic framework for dependency injection using Java annotations in 2008, Guice won the 18th Jolt Award for best Library, Framework, or Component.Google The Thinking Factory
Google: The Thinking Factory is documentary film about Google Inc. from 2008 written and directed by Gilles Cayatte.Open Networking Foundation
The Open Networking Foundation (ONF) is a nonprofit trade organization, funded by companies such as Deutsche Telekom, Facebook, Google, Microsoft, Verizon, and Yahoo! aimed at promoting networking through software-defined networking (SDN) and standardizing the OpenFlow protocol and related technologies. The standards-setting and SDN-promotion group was formed out of recognition that cloud computing will blur the distinctions between computers and networks.
The initiative was meant to speed innovation through simple software changes in telecommunications networks, wireless networks, data centers and other networking areas.By December 31, 2013, the organization had 123 member companies. By June 2014 ONF had grown to over 150 member companies including 24 start-up companies in software defined networking. Member companies include networking-equipment vendors, semiconductor companies, computer companies, software companies, telecom service providers, hyperscale data-center operators, and enterprise users.
Google's adoption of OpenFlow software was discussed by Urs Hölzle at a trade show promoting OpenFlow in April, 2012. Hölzle is the chairman ONF's board of directors, serving on the board along with representatives of the other five founding board members plus NTT Communications Corp and Goldman Sachs. Stanford University professor Nick McKeown and U.C. Berkeley professor Scott Shenker also serve on the board as founding directors representing themselves.In 2016 the ONF announced it would merge with the Open Networking Lab (ON.Lab). The resulting entity retained the ONF name in 2017.Pocket Smalltalk
