  • Yahoo! + Koprol = virtuous circle

    Jakarta, Indonesia — The open-source virtuous circle of community-based reciprocal value and continuous improvement is exemplified by the success story around Jakarta-based Koprol. Starting in late 2008 and more formally in February 2009, Koprol development started, building on Yahoo! developer tools. By November 2009, the Koprol team, led by Daniel Armanto, was presenting their developer tale at the Southeast Asia Open Hack Day, in Jakarta. On May 24, 2010, Yahoo! announced that it was acquiring this really strong team, uniquely suited to Indonesia, Southeast Asia, and emerging markets.

    Indonesia is the world's fourth most populous country, with 230 million people. Its mobile-phone base is expected to reach 200 million in the next two years — and there are twice as many searches from mobile devices than from personal computers.

    The Hack Day presentation

    According to Michael "Smitty" Smith, Director of Global Tech Initiatives, Daniel's presentation showed how Koprol — a located-based

  • Yahoo! Login Leads on Social Web

    Editor's note: This is a guest post from Khris Loux. Khris is co-founder and CEO of Echo, the next-generation commenting system that shares publisher content and aggregates global reactions in real-time.

    Yahoo! is the leading login choice of mainstream users on the social web, says Khris Loux, CEO of Echo, a real-time commenting company. Yahoo! accounts for 34% of logins across top sites tracked by Echo, followed by Facebook (25%) and Google Friend Connect (23%).


    When added to a site, Echo allows logged-in users to share comments across their social networks. Echo runs on a range of login services, including Yahoo! login, Facebook Connect, Google Friend Connect, Twitter, and OpenID.

    Emerging data from use of these new tools indicates that the majority of mainstream audiences hold their affiliation to Yahoo! and Google in high regard. It challenges the notion that to optimize social media connections, publishers need to implement FaceBook Connect or Twitter.

  • Seven Ways the YQL Console Is Easier to Use and More Powerful

    We've been updating the YQL console with new tweaks and features for the last few months. This week, we're providing seven changes that we'd like to highlight. Not all are large, but they either increase the console's ease-of-use or bring more powerful capabilities into it. Paul covers a few of these in his companion screencast.

    Layout Changes

    One of the most immediately obvious changes is the move of the REST query box to the bottom of the screen. This gives you more room for your awesome YQL queries!


    We've also moved a few links around that box and given you the ability to hide the box until you need it. (So you have more room for the result explorer in the middle.)

    Query Aliases

    Late last year, we enabled developers to create nicely named query aliases using a couple of tables: yql.queries and yql.queries.admin. They've been a popular addition to YQL's tables and web service, and now we've made them easier to use by integrating them into the console.

    First, you need to be logged

  • CSUN International Accessibility Conference

    San Diego, CA - This week, Yahoo! accessibility experts will participate at various panels at the 25th Annual International Technology & Persons with Disabilities Conference (CSUN) at the Manchester Grand Hyatt Hotel in San Diego, CA.

    We will also feature an unprecedented opportunity to experience the conference from an entirely new perspective, that of a guide dog named Pecan. Originally created at an internal Yahoo! Hack Day, everyone, at CSUN and worldwide, gets to see Pecan's point of view. Accompanied by her owner, Lucia, Pecan will carry a camera on her harness that will take pictures of CSUN every 30 seconds and send them wirelessly to this SeeingY's flickr photostream. Some photographs with comments are selectively tweeted to Pecan's Twitter stream. (Thanks to Victor Tsaran, Ted Drake, and YDN's community manager Robyn Tippins for their handiwork in developing this prototype.)

    The following Yahoo! accessibility experts will deliver presentations: Victor Tsaran, Yahoo! Senior

  • To Silvia let us sing

    I am a technical content producer on the Yahoo! Developer Network, and how I became a technologist has much to do with Sylvia Dorffi. She and pioneering computer programmer Ada Lovelace were kindred spirits.

    Aunt Sylvia started her work life as a hairdresser and took night classes to learn design drafting. Afterwards, she became a draftswoman at Appleton Electric in Chicago, designing cable reels. After more night classes, she earned her electrical engineering degree and worked as an electrical engineer for the rest of her life.

    Aunt Sylvia wasn't only curious intellectually. She was also a single woman who fearlessly explored the world. Which is how she came to visit her brother Bob, my father, in the Philippines.

    Bob and sister Sylvia were born into one of the "Great Migration" Finnish immigrant families in Michigan. Dad ended up in the Philippines with the U.S. Navy in World War II. Staying behind after the war ended, he met and married my Filipino mother, Lolita.

    In the 1960s, Aunt
