Black Duck Open Hub, formerly Ohloh, is a website which provides a web services suite and online community platform that aims to index the open-source software development community. Black Duck Open Hub is not a well known site and as such few have tried to source in it. Well to do this without you need go no further than into your bag of tricks and pull out an old tried and true tool, called x-raying.
So, to source within Black Duck Open Hub you simply need to create an x-ray string, like the one below.
site: openhub.net/accounts java
If you run the strings above in google you will get the results below.
Then use your social detective skills and you are set.
If you need more info on X-raying see my blog post http://www.recruitingblogs.com/profiles/blogs/seeing-what-is-really-there-a
Until next week may the source be with you!!
