Yahoo Developer Network (YDN)
• Open Source
• Developer Tools
• Data Services
Yahoo! Open Strategy (YOS)
YQL Code Samples
Open Strategy :: Applied
6
• YUI
• Hadoop
• Apache
• PHP
• Perl
• MySQL
YDN :: Open Source
7
• YSlow
• Pipes
• Blueprint Mobile Widgets
YDN :: Developer Tools

• SQL-like syntax
• Allows you to query (SELECT), filter
(WHERE) and join (IN) data across
WebServices.
• Self Describing - SHOW, DESC table
• Public / Private Data
• Bindings for many YDN APIs
• Can query external structured data (USE)

Yahoo! Query Language (YQL) - SELECT * FROM internet
11
<query yahoo:count="46" yahoo:created="2009-02-20T08:16:03Z" yahoo:lang="en-US" yahoo:updated="2009-02-20T08:16:03Z" yahoo:uri="http://query.yahooapis.com/v1/yql?q=show+tables"> <results> <table>atom</table> <table>csv</table> <table>feed</table> <table>flickr.photos.exif</table> <table>flickr.photos.info</table> <table>flickr.photos.interestingness</table> <table>flickr.photos.recent</table> <table>flickr.photos.search</table> <table>flickr.photos.sizes</table> <table>flickr.places</table> <table>flickr.places.info</table> <table>geo.places</table> <table>geo.places.ancestors</table> … </results></query
YQL :: SHOW tables

YQL :: DESC flickr.photos.search

1. Download the SDK
http://developer.yahoo.com/social/sdk
2. Unzip yos_php_sdk-1.1
3. Get a Developer Key
http://developer.yahoo.com/dashboard
4. Start to write some code
Developer Key / PHP SDK

<?php// Include the PHP SDK for YSP library.require_once("yosdk/lib/Yahoo.inc");
// Define values for keys required for authorizationdefine(CONSUMER_KEY,"dj0yJmk9ZDNwaXdQSEZ…j");define(CONSUMER_SECRET,"37fe717538e0598e6c70d4262…");
// The YahooApplication class is used for two-legged authorization, which doesn't need user authorization.$two_legged_app = new YahooApplication(CONSUMER_KEY,CONSUMER_SECRET);
// Create queries for Flickr$yql_request = 'select * from flickr.photos.search where user_id="28569531@N00" and text="jump" limit 6';
// Make the request$results = $two_legged_app->query($yql_request);$photos = $results->query->results->photo;
// Build the output HTMLforeach($photos as $k=>$v) { $imgs .= '<img src="http://farm' . $v->farm . '.static.flickr.com/' . $v->server . '/' . $v->id . '_' . $v->secret . '_m.jpg" alt="Image' . $k . '"/>' ;}echo "<html><body>" . $imgs . '</body></html>’;?>

Key learnings
26
• Developers are lazy
• Developers are impatient
• Developers are opinionated
• They look under the cover, analyze, hack.
• Of course they are smart, innovative and driven to optimize!
• Your success depends on that!
Learnings :: Developers are …
27
Value => Adoption
• Solve their problems
• Help them be efficient
• Standards instead of buzz words
• Facts instead of slogans
• Time!!!
Learnings :: Developers are lazy
28
• Capture their interest – direct it quickly
• Fast access to high value offers
• Easy signup
• Quick start guide
• Build on what they know
Learnings :: Developers are impatient

31
Learnings :: Content Structured
32
Learnings :: Content Visually Organized
33
• Developers are connected – Online and offline
• Your product gets discussed in public forums
• You should be part of that discussion
• If you don’t build a community around it, they will
Learnings :: Developers are opinionated
34
• Join developer channels to communicate (not to market)
• Twitter, Message Boards, Blog comments, IRC
• Slideshare
• Del.icio.us, Flickr, Upcoming
• The right events - Unconferences
• Provide value, have conversations, share code
• Be accessible, embrace feedback
Developers don’t respond to formal marketing!
Learnings :: Developers are opinionated contd

Kelvin
• Know your winners
• Measure as much as you can
• Web site stats
• API calls
• Forum post
• Personal interactions - documented feedback properly
• ...
• Keep doing what works – Fix or retire what’s broken
Learnings :: Metrics
36
• Set expectations, communicate a roadmap / vision
• Avoid pre-announcements
• The macro affects the developer products
• High appreciation of events outside of Silicon Valley
• Coding competitions rather then car give aways
Learnings :: Others
