  • The opening presentation from the 2nd annual Hadoop Summit, presented by Shelton Shugar, Yahoo!'s SVP of Cloud Computing. You can also watch the video presentation in full.



  • This past weekend YDN attended the 2009 edition of OverTheAir, the mobile meetup which took place in Imperial College, London. It was two days of incredible fun, good presentations and interesting hacks (including a colourful attempt to recreate Dr Who's Holodeck).

    The whole event was full of good happenings, from the threatening presence of a full-size Dalek guarding the beanbag area to the superinteresting Teen's Dragons Den session, where several teenagers judged if they would invest in the different mobile companies some of our mobile entrepreneurs were presenting.

    We had the opportunity to attend several talks, around such hot topics as mobile accessibility, augmented reality, widgets from different platforms, and how to properly design mobile applications.

    From YDN we also contributed talks on Blueprint for Mobile sites and how to use Yahoo APIs to add more value to your mobile application. The slides are published in slideshare at

  • Build Apps for the New Yahoo! Homepage

    Today there are nearly 400 apps available for Yahoo! homepages around the world. Will yours be one of the innovative and flawless apps that makes it into the homepage gallery next?

    Now, you can build apps that run on the new Yahoo! homepage, which gets over 330 million unique visitors per month worldwide. By building apps, you can drive traffic to your site, acquire new users, and increase awareness of your brand. You can also display ads and make money through virtual goods. We’re working on an array of additional developer monetization opportunities – these will be available soon.

    Like the open apps on My Yahoo!, homepage apps are built with the Yahoo! Application Platform (YAP), which allows you to build and distribute an app that any Yahoo! user can install (see how the user experience looks). Raise awareness of your app through traditional mechanisms (email, ads, etc.) and use “Add to Yahoo!” buttons to encourage installs. Your app installs will also be reflected in Yahoo! Updates

  • As the Yahoo! Application Platform (YAP) matures and is introduced into new drop zones throughout Yahoo!, many questions have come up about developer support and the best new features. There have been numerous suggestions from our community and we have looked into many of the questions and concerns raised by our users. To that end, we have implemented significant technology upgrades to make the lives of YAP developers much easier, and that is what I want to outline in this post. I want to highlight some of the best updates to the platform and additional tools that developers may find useful.

    YML:Include Tag

    We have heard from developers that you would like to allow the small view of a YAP application to be more dynamic, or build content each time the user views the application. This was a valid concern and is one that we have addressed with the yml:include tag. This tag will allow you to automatically make a server-side request for content once the application loads. In doing so,

  • Whaddyathink? Logo
    As seen on My Yahoo!, we’re proud to announce the Yahoo! homepage integration of the Ask and Answer application (the application formally known as Whaddyathink?). When running through your daily news digest on the Yahoo! homepage, now you can take a break to answer your most difficult questions. Let your friends plus the public help you decide – kind of like having unlimited lifelines on “Who Wants to be a Millionaire,” but without the crushing disappointment of losing because of an audience that refuses to be correct!

    Voting - Now With More Oomph!

    Whaddyathink? Logo
    Polls made up of just your friends seem biased, right? Well, with Ask and Answer, your friends can participate, but they don’t necessarily have to influence your polling decisions. You choose. Now you can vote on the polls of random strangers without risking any broken friendships – and you can get honest feedback from the masses. The votes of strangers naturally are weighted lower than your actual friends. Your friends will be floated

  • Every Thursday is Tech Thursday where we share a random assortment of technical links we found and liked.

    • Chrome Frame is a plug-in for Internet Explorer to make IE display the page using Chrome as the rendering engine. As explained in the technical details article it is implemented as a Browser Helper Object, uses IE's cookies, history and password-remembering, includes the WebKit developer tools and appends 'chromeframe' to the regular IE user agent string. All in all the feedback from the tech scene is very positive but there are also accessbility concerns about the solution.
    • If you don't want to switch and fully support IE6 then there's quite a detailed Internet Explorer 6 bug fixing cheat sheet.
    • The latest nightlies of Safari and Firefox now include WebGL which means that there are some cool 3D browser apps ahead. Check out the video showing a Spore creature inside the browser.
    • Vitamin D is an interesting technology to automatically detect objects in videos. Check the report for

  • The HackU team spent last week at the University of Illinois in Champaign. This is the 4th year there for HackU.

    The enthusiasm was high throughout the week. I kicked it off on Monday night with an intro to Hack and some short examples of our various APIs including Flickr, Context Extraction, GeoPlanet, Placemaker, YUI, YQL, and BOSS.

    Tuesday, Paul Tarjan talked about SearchMonkey and the Semantic Web.

    Wednesday was YQL/YUI Tech Night led by Tom Hughes-Croucher where he walked the students through YQL step by step.

    Hacking began Thursday night at 6pm. The hacking atmosphere was good with snacks and food for all. For some reason people had particular problems with AJAX and JSON this time around and we spent a fair amount of time explaining same-domain policy and trying to debug Django/JQuery issues since a number of students chose to use those.

    In the end, we got a number of high quality hacks, and also a fairly high number of unfinished hacks, many of which never even presented.

  • Today we announced the new Yahoo! Search Results Page, which ships with a wide array of rich new features. What you might be surprised to learn is that the new design is actually a little faster than the original. Through diligent use of modern performance techniques, we not only held the line on the total page size and number of HTTP requests, but we also made a number of improvements to the load time of the page. Now that you've seen the new search results page, let's walk through some of the performance considerations we used when constructing the new template.

    Code Refactoring

    Any sweeping design change like this is a great opportunity to refactor, and we took full advantage, rebuilding the Yahoo! Search page's HTML, CSS, and JavaScript foundation from scratch. If you think of the template as a shell that wraps the "10 blue links" in the center of the page, all the markup around the middle content well has been rewritten. This allowed us to get rid of old cruft and take advantage

  • It's time for the YDN International team to head back to Paris. We were last there in April, talking about Fuel for a great web experience.

    This time, we are focusing on the Yahoo! Application Platform or "YAP."

    The Yahoo! Application Platform allows you to reach Yahoo's users and improve the Yahoo! user experience by building applications for Yahoo! pages, such as the Yahoo! homepage.

    This event will be a technical workshop led by Yahoo! developer evangelist and Paris favourite Christian Heilmann.

    It will give an overview of the technology, including some examples of applications that have already been developed, followed by a deep dive into the YAP platform.

    After some refreshments, there will also be an opportunity to get "hands-on" with YAP, as Yahoo! engineers step you through creating a sample application.

    The event will be held at La Cantine on Wednesday 7th October, starting at 7:30pm and will be held in English.

    Christian is staying on in Paris to speak at web development

  • We're happy to announce support for the OpenID OAuth Hybrid Protocol, which combines OpenID authentication (sign in) with OAuth authorization (access control) in a single interface. The Hybrid Protocol makes it easy for the hundreds of millions of Yahoo! users to sign into websites with a Yahoo! account, and to enable two-way data sharing of their Profile, Contacts, and Updates, without having to register a new site-specific account or share their Yahoo! password.

    Plaxo is one of the earliest adopters of OpenID, allowing their users to sign into Plaxo using a Yahoo! account with just a couple mouse clicks. Instead of requiring first-time Plaxo users to manually verify their Yahoo! email address by sending a verification email, Plaxo uses OpenID Attribute Exchange to verify Yahoo! email addresses without forcing users to wait at their mailbox for the verification email to arrive. Building on their successful experience with Yahoo! OpenID, Plaxo is experimenting with the Hybrid Protocol:
