  • Neal Sample on Yahoo’s Open Platform at Web 2.0 Expo

    Many of you probably saw the video of our CTO, Ari Balogh, give a 15 minute keynote talk at the Web 2.0 Expo about our forthcoming platform for developers. While Ari did a very good job of presenting a high-level overview of Yahoo's Open Strategy (YOS), there's only so much one can say in 15 minutes.

    As a follow-up, Neal Sample (YOS Chief Architect) gave a 40 minute deeper dive presentation last Friday. In this video he begins with a recap of the information presented in Ari's keynote and then spends time providing more in-depth explanations and examples of the various YOS platform components: update notifications, social connections, the activator, and more.

    Expect to see more and more in-depth videos with various YOS engineers in the coming weeks and months.

  • Badges for Yahoo! Pipes

    I've been a big fan of Yahoo! Pipes ever since it launched. Pipes is unique in making the world of feeds accessible and "mashable" in a friendly browser-based development environment.

    But it's always felt like there was a missing piece too. Pipes is easy enough for novice (or even non-) programmers to use, but what it ultimately produces is a data feed intended to be consumed by a program.

    Pipes Badges change all that. If you can add a one-line script tag to a web page, you can visually display the output of a pipe on you own web site. To learn more about this, I got together with Paul Donnelly for a demo. Here's the video.

    You'll notice that these badges do more that render an RSS feed as a list. If the feed contains photo data, you can get a slide show. And if the feed contains geocoded data, you can get a map badge.

    In my mind, this is the first of several steps to making pipes output more useful to a larger class of data junkies.

    Thanks to Paul for making time to go over

  • Flickr Uploadr: Open Source and Powered by XULRunner

    When version 3.0 of the Flickr Uploadr came out, we Flickr users got a significantly more useful tool for getting photos online. But things changed significantly behind the scenes as well.

    First off, the new Flickr Uploadr is built on top of Mozilla technology--XULRunner to be specific. If you haven't heard of XULRunner...

    XULRunner is a Mozilla runtime package that can be used to bootstrap XUL+XPCOM applications that are as rich as Firefox and Thunderbird. It will provide mechanisms for installing, upgrading, and uninstalling these applications. XULRunner will also provide libxul, a solution which allows the embedding of Mozilla technologies in other projects and products.

    The choice to build on XULRunner is something that I discussed with Richard Crowley. Building on top of a Mozilla engine isn't new, of course. ActiveState has been doing so for years now for their Komodo IDE, as ActiveState founder Dick Hardt and I discussed in this interview at the 2007 Defrag Conference. The

  • A Conversation with Matt Mullenweg

    A few weeks ago, Matt Mullenweg (co-creator of WordPress) came by Yahoo to talk to a bunch of Yahoo! bloggers about the current and future state of WordPress. After the meeting, I sat down with him for our Developer Spotlight series on YDN Theater to catch up on various topics.

    In this 12 minute interview, we talk about:

    • Turning 24
    • Surprising uses of WordPress
    • The next big WordPress release (new features)
    • Scaling Automattic and
    • bbPress (Automattic's message board software)
    • PHP4 vs. PHP5
    • PHP vs. other languages for web development

    Thanks to Matt for coming to visit and taking the time to talk with me on camera.

  • Yahoo! OpenID Provider service now available as a public beta

    Today, we are launching the public beta of the much-anticipated Yahoo! OpenID Provider service. This means that users with a Yahoo! account - all 248 million of them - will be able to sign in to any website that supports OpenID 2.0, the latest version of the OpenID specification.

    In case you are curious, here are the key features of this release:

    • Usability - Users will not have to understand the technical details of OpenID simply to use the technology. Thanks to features introduced in the OpenID 2.0 specification, users will not have to type their OpenID URL while signing in to websites. They can simply type in the OpenID textbox or, if the Relying Party website provides it, click a button that takes them to Yahoo!. By not requiring users to understand the meaning of an OpenID URL, we hope that more users will be able to overcome the initial hurdles of using this new echnology. For those of you who want to set up a custom URL, we will provide a way to do so, including the

  • OpenID Support at Yahoo!

    In case you missed the news (official press release), we announced support (starting at the end of the month) for OpenID 2.0 on both and earlier today.

    As explained on the What is OpenID page:

    OpenID eliminates the need for multiple usernames across different websites, simplifying your online experience.

    We've added an OpenID section to the Yahoo! Developer Network that provides more details for anyone wishing to integrated with Yahoo! using OpenID. Included there is a FAQ that covers a few things you may need to know.

    We're looking forward to a whole new wave of lightweight personalized applications as adoption of OpenID increases around the Web.

  • Memcached Hackathon at Yahoo: December 13-14th 2007

    There are a lot of memcached hackers and power users in the Bay Area, so we're proud to be hosting an all night hackathon in a couple weeks.

    Hack and code memcached. Active developers from the community will be joining us along with fellow Yahoo's for an all-night hackathon. We are working towards shipping new features and releasing the binary protocol. Drinks and food provided!

    As the Hackathon Wiki says:

    Pretty simple: it's a marathon coding session. The goal is to get something done. Come armed with a pet project of your own if you like, or just with some energy and a willingness to think hard and pound out code. It has a scheduled start time, and it ends when it ends.

    Register on Memcached Hackathon @ Yahoo Campus. That'll help us figure out how much pizza to have on hand. :-)

    Oh, and in case you're wondering, we do use memcached on a number of popular Yahoo! services. Drop by and you might get to meet some of the engineers behind them.

  • New YDN Blog: Hadoop & Distributed Computing

    This is just a quick note to point out the newest addition to the family of YDN blogs: Hadoop and Distributed Computing at Yahoo!, a blog that'll focus on the Hadoop open source project and related distributed computing topics.

    We're kicking off the blog with a video interview of Eric Baldeschwieler ("Eric14"), Yahoo's Director of Grid Computing. That means he manages the Hadoop Team at Yahoo.

    In case you missed it, we recently announced a partnership with CMU that will help numerous students, professors, and researchers harness the power of Hadoop in their work.
