New from BOSS: Structured Data and More
Posted February 11, 2009
Yahoo! Search BOSS announces three new features and an important update on pricing. Developers can now use the BOSS API to easily access structured data derived from SearchMonkey. The updated BOSS API also includes expanded search result abstracts, Site Explorer inlinks, and relevant page data.
The Terms of Service for the BOSS API have changed to allow developers to use third-party monetization platforms. We've also announced a pricing plan that will become effective later this year.
Make the most out of search: check out the new BOSS.

Douglas Crockford on "Ajax Performance"
Posted January 7, 2009
Douglas Crockford returns to YUI Theater with a new installment of his multi-part lecture on JavaScript. This session, "Ajax Performance," covers the use of Ajax techniques to improve web-application performance. Douglas argues that the use of Ajax to reduce the number of JavaScript and DOM objects in a given page is the single most important perfomance optimization that most web applications can make.
Watch the full video on Yahoo! Video, check out the downloadable version, or read a transcript of the talk.
