Matthew McCullough

This session will survey a wide range of tools across the Java space. We'll look at utilities such as VisualVM, jstatd, jps, jhat, jmap, Eclipse Memory Analyzer, jtracert, btrace and more. Open Source is not just a suite of libraries you consume within your application, but now reaches into the space of tools to help you troubleshoot and improve your applications. The price of these tools eliminates barriers to their use and their open source nature allows you to mix and match them into compositions that work well for your application's unique debugging needs. These tools will help you peel away layers of your application to expose bugs and performance xeilings. We'll interactively analyze the heap and garbage collection cycles of both local and remote applications, take snapshots of heap, query the heap for heavy usage, leaks and augment running code without reboot and without breaking a sweat. After attending, you'll never look at Java debugging the same way again

This fishbowl will initially contain Matthew McCullough and Tim Berglund. An informal study shows as many as 70% of today's public facing web apps are not using hashing of passwords and are storing customer data in the clear. As professional engineers, we need to step up to our responsibility to secure customer information. In this fishbowl, we'll discuss approaches being taken to encryption on the wire, in the DB and on disk. This can have implications all the way back to domain driven design and separation of concerns. We'll solicit inputs on what folks at the conference are struggling with in this area, why encryption usage is so rare, and what we can do as thought-leaders to increase customer data security in our applications. The idea with a fishbowl discussion is that you have 5 chairs, you may only speak when you sit on a chair, and one must be empty at all times. If someone sits on the last chair, someone else must get up. The chairs are initially occupied by two or three of the conference speakers, to get the discussion going. Other conference participants are encouraged to join in by sitting on an empty chair. Anyone sitting in the fishbowl who finds they no longer have anything they really want to say, should consider giving up their place.
