Bitly is a great URL shortener which also provides a very neat API. If you’re as API driven as me and love to automate the tasks around you, you’ll be happy to note that there is a new open data table that can shorten URL’s using YQL.

On 29th April ‘09 we released YQL Execute out into the open. You can find the actual release blog on yqlblog.net. We also released the following screencast which gives an overview of YQL Execute.
Here’s the direct link to the YQL Execute Screencast on YDN. In the screencast, Sam Pullara gives an introduction to YQL Execute and I follow it up with a demo to show the power of this new feature.
For folks who prefer to read and follow the tutorial instead, here is the transcript of the entire demo along with the YQL queries as well as the Open Data Tables used to create the examples.
I recently had the opportunity to give a tech talk on YQL at OpenHackday ‘09 in Bangalore.
Open Hack Day was an awesome event. It was very well organized and provided the ideal medium for hackers to put forth their ideas. Read the rest of this entry »
YQL Queries FAQ:
YQL provides tables which let you access the social profiles, connections, contacts as well as updates of a Yahoo User. The actual apis around which YQL builds can be found at http://developer.yahoo.com/social/. A compilation of questions and answers on the various social tables provided by YQL are listed below. More specifically, this post deals with questions about how to get the necessary data (guids) which can then be used for querying the social tables. Read the rest of this entry »
Introducing OAuth-ify/OAuthProxy, a service that performs two legged OAuth calls to backend webservices. As of today it only supports YQL.
Motivation:
With two-legged OAuth, there are only two parties involved i.e. the consumer of the api and the service provider. It doesn’t deal with user credentials or other private data that come into the picture with three-Legged OAuth. YQL is one of the services which uses OAuth exclusively for all webservice access. (apart from the console)

After months in hiding, I can finally talk about the stuff I’ve been working on.
I was involved in creating YQL and was responsible for leading the query engine implementation. I am very pleased to see it being released to the public today. Check out Jonathan’s talk which gives a great overview of YQL. (Jonathan’s posted about the YQL Launch here)
YQL adds the simplicity and self describable nature of SQL to the Web. In addition to this, you can also join disparate webservices with common keys. For example Yahoo’s “guid” can be used to join many common webservices which are keyed on “guid”s.

It’s pretty common to encounter a situation where you want the following question answered.
“Find me the java packages in classpath ‘X’ which are already present in ‘Y’”
where X = Classpath of an application;
and Y = System Classpath or some other classpath
I wrote a small command line utility which answers this question and groks the list of duplicate patterns. For WebLogic Server users, this tool finds the duplicate packages and also emits some xml which can be pasted into ‘META-INF/weblogic-application.xml’ to ensure that the version in the application always wins.

My JavaPolis ‘06 talk on “Java EE Enhancements for Real World deployments” is now online here. I’ve uploaded a PDF version of the presentation which can be found here. The talk describes key enhancements in WebLogic Server such as Application Libraries, Side-by-Side deployment and deployment plans which aid in real world deployments. Do let me know if you have any comments or questions.
JavaPolis ‘06 was held in Antwerp, Belgium from Dec 11th through 15th. It had all the elements of a perfect developer conference - Beer, geeks, frites and more geeks. Our bea booth had Lafe on tap which made it a lot easier to talk about very deep and serious topics 
Thanks to the JavaPolis organizers for making the talk available online. It’s easily one of the best java conferences I’ve ever been too. Unconventional and original! is how I’d summarize the conference in two words.
I came across this amazing talk by Merlin Mann. A must for every person who intends to be productive with Email.
I happen to be an IntelliJ fan but seeing many of my collegues use eclipse, I decided to give it a try. The experience was really good. I could add have various unrelated projects open in the same navigation bar and work on a single one in the editor. I typically have a few skunkworks sandbox type projects which I work on while commuting (in BART) and I want them readily available. The other thing I really love about Eclipse is the startup time. I load up quite a huge chunk for the WebLogic code but I dont want all the code loaded as soon as a I startup. Eclipse really does this right and Intellij (atleast 5.1) needs improvement here. So far so good.
