The folks at Rebel Labs picked Jenkins as the last installation of their technical report series. It is a beautifully crafted 50 page PDF that covers the overview of the technology. You get to see a bit of details about how ZeroTurnaround uses Jenkins, and it contains a section where I get interviewed by them.
Also, while they failed to mention this in the document, you can use JRebel when developing Jenkins plugins and it'll reduce the # of times you need to restart the VM. To the extent that you use it to develop open-source Jenkins plugins, you can apply for a free OSS license, too.
If that sounds interesting enough, you can get your copy now. Be forewarned that a registration is required. About the Author
