I see a lot of node.js work here... I'll be the super-uncool guy in the group and admit that so far I've only ever released Java libraries under Apache 2.

I just released a CloudFront log parsing library: http://www.thebuzzmedia.com/software/cloudfront-log-parser/

and a simple XML parsing library (speed of pull-parsing with the ease of XPath-esque expressions): http://www.thebuzzmedia.com/software/simple-java-xml-parser-...

and one library that seems to be picking up is an image-scaling library I have made a few releases of: http://www.thebuzzmedia.com/software/imgscalr-java-image-sca...

There are a handful of other libraries: https://github.com/thebuzzmedia/

I just haven't finished the project-pages for them.
