Node.js and Benchmarking it on Mac

I'm looking through node.js which is a webserver with javascript code. So one of the cool features is that all of its commands are non-blocking! the server just keeps running. There is no mutex or multi-thread locks or deadlocks etc.

If you test it with ab command which is apache benchmark for webservers. ab already ships in Mac

Hadoop Meetup

Today I went to a Hadoop Meetup event where people shared their fair piece of wrestling with Hadoop. The discussion were mostly around search, scalability, fault tolerance, workflow and responsiveness. There were a ton of challenges that from outside you might think that they are not big of a deal but when you get to do them it takes a good man's efforts to solve. The main host was the Grooveshark music streaming company with over 60 employees in two offices one here in Gaiensville, FL and another in New York. The next meeting we would be talking about Hadoop workflow, Oozie by Yahoo, Azkaban by Linkedin, etc.
