  • OAuth Update #2

    On Wednesday, upon discovery of security issue within the OAuth protocol, we disabled the ability for users to authorize new applications via OAuth on Yahoo! (apps that had already been authorized were not affected). Obviously, this has been a challenge for you as developers since you haven?t been able to test any apps that rely on our Y!OS Updates, Social Directory, Status, Contacts, or Fire Eagle APIs .

    After working on the problem yesterday, we?ve now decided to turn OAuth back on for developers testing their own apps on Yahoo!, but with the addition of a new interstitial warning screen preceding the normal Yahoo! OAuth permissions flow. Here's a screenshot of the warning screen:


    Basically, we?ve decided to re-enable OAuth so that you can test your own apps and not slow down your development cycles. If you choose do so, we recommend creating a test account and using test data.

    Please keep in mind that we are strongly discouraging Yahoo! end-users from authorizing new apps that use

  • Jelly Talks Geo: Skyhook & Fire Eagle live @ betahouse tomorrow

    Join me on Friday, April 24, for the 4th
    International Jelly Talk, streaming live from betahouse in Cambridge, Massachusetts. Ryan Sarver (of Skyhook Wireless) and I (Seth
    Fitzsimmons, of Yahoo!’s Fire Eagle) will be discussing geo-technology and the Web. We’ll start at 2pm EDT (11am PDT).

    Skyhook is well-known for Loki, a product which adds location information to any website. This approach has been adopted and
    adapted into the W3C’s Geolocation API and is beginning to make its way into browsers as an emerging standard. Mozilla Labs’Geode makes this API available to users of Firefox 3.0. Google Gears makes a similar
    API available for all platforms it supports.

    Fire Eagle takes an alternative, complementary approach that works behind the
    scenes and allows network-based services to respond to your location, whether
    you’re online or not.

    We’ll be discussing the notion of “location” generally, as well as specific technologies, services, and tools that are available, such as Yahoo!’s

  • Thirteen Variations on the Theme of Open and Other Insights from BayCHI

    127248243_5d7023d316_m.jpgIf you're a worker on the web who lives in the Bay Area, you owe it to yourself to check out BayCHI, the San Francisco Bay Area Chapter of ACM SigCHI (a Special Interest Group on Computer-Human Interaction). BayCHI "brings together scholars, practitioners, and users to exchange ideas about computer-human interaction and about the design and evaluation of human interfaces." You don't have to be a web designer or developer to benefit from BayCHI's offering, whether you're looking for community, fresh perspectives, stimulating talks and meetups, networking opportunities, or interesting projects in need of volunteers.

    BayCHI's monthly program meetings are hosted at PARC (formerly Xerox PARC) in Palo Alto on the second Tuesday evening of every month -- they are free and open to the public. Over the years, I've attended presentations from a firmament of web stars -- including Google's Larry Page, Digg's Kevin Rose, Flickr co-founder Stewart Butterfield, and Slideshare co-founder (and

  • Georgia Tech Hack U, come rain or come shine

    Yahoo! Developer Network evangelists, including one Georgia Tech alum and one Chick-fil-a lovin' son of the South are joining forces with the Hack U crew for the third of our Yahoo! Open Technology talks, Thursday night in Atlanta. This event takes place at Georgia Tech's College of Computing as part of a weeklong program of coding workshops and tech talks that Yahoo! offers to computer science undergraduates.

    Hack U gives us at the YDN a chance to meet up with students, help with the hacking, and see how the next generation of developers responds to the stuff we're building at Yahoo!. It also gives us a chance to invite folks from the local developer community to learn about Yahoo!'s developer tools.

  • YDN goes to school in Seattle

    Yahoo! evangelists and other developer network crew are heading up to University of Washington in Seattle to serve up a little YDN juice with the usual Hack U menu. We've got two Yahoo! Open Technology Talks scheduled and the developer community outside the campus gates is invited to attend. Both events take place at the Paul G. Allen Center for Computer Science & Engineering, which looks like a wonderful space for a hack event, even if the sun isn't shining in the Emerald City.

    Someone on the yuiblog wanted to know who is coming. Here goes: The Thursday night talk on February 19 features Yahoo! software engineer and technology evangelist Jon LeBlanc, who works with the Partner Integration group in the Yahoo! Developer Network. If you've spend any time on the YOS forums, you've probably already met him. Jon is a Canadian, born with native geek cred: a camelcase last name.

    On Saturday afternoon, February 21, as part of the HackU demos and closing festivities, JavaScript guru and

  • It must be Jelly

    Tomorrow, Friday, February 13, Yahoo!'s Buzz Marketing team lends its support to Jelly, a casual coworking initiative (movement?) created by energetic entrepreneur and master of collaboration Amit Gupta, for the second-ever JellyTalk event. This week, author, entrepreneur, and Silicon Valley sage Guy Kawasaki, the man who reinvented the word "evangelist" for the tech industry, will be the speaker at a still undisclosed San Francisco Jelly location!


    What is this Jelly thing? A Jelly is a free, sometimes ad hoc co-working environment, where developers, designers, writers, code warriors, four-hour work-weekers (are there any left?), and all kinds of caffeinated creatives get together to work in a common space that fosters cross-pollination of ideas and practices, and interesting conversation. The concept behind JellyTalks: add a notable speaker, a comfy venue, stream a live webcast, provide live chat, and don't forget to tweet early and often.

    The JellyTalks series launched last
