There'll be several talks that touch Jenkins. The first is from me and Jesse called Next Step in Automation: Elastic Build Environment [CON3387] Monday 12:30pm.
Then later Tuesday, there's Building a Continuous Delivery Pipeline with Gradle and Jenkins [CON11237] from Benjamin Muschko of Gradleware.
Thursday has several Jenkins talks. One is The Deploy Factory: Open Source Tools for Java Deployment [CON1880] from Bruno Souza (aka the Java Man from Brazil) and Edson Yanaga. In this same time slot, guys from eBay are doing Platform Upgrades as a Service [CON5685], which discusses how they rely on automation to make platform upgrades painless.
