Why do people release code at all?

A BCG/OSDN Study found that open source developers aremotivated by:

Intellectual Curiosity/Stimulation (44.9%)

Skills Improvement (41.3%)

Work needs (33.8 %)

Open Source Idealism (33.1%) Non-Work Functionality (29.7%)

Professional Status (17.5%)

Reputation building within Open Source (11%)

Dislike/distrust of proprietary software (11.1%)

Implications:

OSS Developers understand OSS licenses.

They know they are giving away their software.

They know and hope people will use it.

The majority expect no more $$$ for the work.

If they did, theyd just do it as a commercial offering, if they

can. Which is pretty remarkable.

What is Google

17

In-house rack design

PC-class motherboards Low-end, large size storage and

networking hardware

Running Linux + in-housesoftware

How does Google use Open Source?

As Infrastructure

Linux kernel

Many Apache Project Tools

SSH, and other system management tools

The Languages and compilers that we use.

Engineers and others running Linux (Goobuntu)As building blocks

Our repositories have hundreds of libraries used in Google

software


19/33

19

But Why does Google use Open Source

Control and Ownership

Maintain our independence from external softwarecompanies

Adaptability and Flexibility

We can drill down to repair and enhance our services

If we want to do something out of the ordinary, we can do sowithout showing our hand

No one is incentivized to hurt us

Roots Appeals to the Google ethic

We release open source code

We Patch into hundreds of projects each month

Strategically important

Helps the internet grow fairly.

~900 projects to date.*

API Examples

Dev Tools

Linker Build/test

Memory and thread management

Plugins for eclipse

DVCS patches.

Infrastructure

Approximately 18m lines of code released

25/33

Major Projects: Chromium

What is it: A browser

What license: Mostly BSD (some lgpl)

What does it do?

Incredibly Fast

Safe, smart, sandboxing Multiple processes/tab.

Implements HTML5

Offline, Worker pools, Geo-location, File uploading Desktop like experiences inside the browser

ChromiumOS, (demostration)


26/33

Major Projects: Android

What is it: Full cell phone OS.

What license: Apache + Linux Kernel

What does it do?

Raises the minimum bar for smart phone os

Allows for a solid web experience Allow for multiple applications to co-exist.

Provides a smart app marketplace.

Makes cell phone development a snap. >250,000 devices sold worldwide across many carriers

per day.


27/33

WebM/WebP

What it is: WebM is an open, royalty-free, media file formatdesigned for the web.

Vorbis Audio

Vp8 video

In a matroska-like container

Very high quality

Releasing in a very open source way.

Bsd licensed

Patents granted freely, no fees required.

Our goal is to get html5 to recognize webm as a standardcodec for web video/audio.


28/33

What is VP8

A Transform based codec based on the same basicparadigm as its main rivals. But the devil, as always, is inthe detail.

Based on VP7 (as used in Skype) but with many newfeatures.

Top flight compression performance but lower underlyingcomputational complexity than its main competitors (even

than VP7). Designed with multi-core and custom silicon devices in

mind.

Extensive use of char math to maximize the benefits fromSIMD.

Support for pseudo-SIMD even on processors with no

dedicated SIMD instructions.

29/33

Some Longer Term Engineering Goals

20% improvement fixed quality

75% improvement to encoder speed

50% improvement to decode speed on windows

Implemented in Google-Talk

Implemented in make the web faster project - Images?

Hardware Support Support in 50% of all external apps that use video.

Improved Feature Set like Scalability

The Summer Of Code, 2010

1049 students

150 Organizations

Over 2000 Mentors

>6000 applications

94 Countries

81% pass rate!

~3 million lines of code in 2009 alone

(~13m since 2005)


32/33

32

How it Works

1) Student applies to work on a project for, say, the ASF

2) ASF mentors review the application and accept the student

3) Google pays student $500 for being accepted

4) Student works with an ASF mentor to create project

5) Mid-Term, good students are paid $2250 by Google

6) Student continues work with mentor to create project

7) Final: If the student has completed the goals set forth in theapplication and student is paid $2250 by Google

8) Successful student gets t-shirt, certificate and valuable experience

along with the money.
