6:00-7:00 PM Cappuccino

It's 2009 and all the late-1990's hype of the browser as a "rich application platform" is finally starting to materialize.  All is not well, however: developing in Javascript is a chore, there are still significant differences between browsers, and creating the rich, desktop experience users are expecting is a difficult task.  Enter Cappuccino: a new and exciting RIA framework that helps align the web development experience with that on the desktop and helps create fantastic user interfaces.  In this talk, Johnny will explain why Cappuccino matters, what it looks like, how it works, and how to hook it up with your existing Java services.

6:00-7:00PM: Mule ESB - integration simplified

Okay, so the economy is still in shambles. More companies than ever are working with a downsized workforce. You have been asked (again) to do more with less. Since that project to replace the legacy back-end application got shelved for now, you have to go back to the drawing board and integrate your new web applications with that same legacy application. And, of course, you have to do it in record time.

This talk introduces Mule ESB, an open source application that can simplify your integration projects. With an elegant, but simple architecture, Mule can provide an excellent foundation for your next integration project. Not only can it speak all the basic protocols (JMS, HTTP, FTP, Email, JDBC, File, etc.) out of the box, but it comes with a set of rich features for web services, message routing, transformation and transaction management. Topics discussed include: messaging patterns, service endpoints, routing, transformation, & protocol bridging. And, yes, you will see some code in action!

About Rich Remington

Rich Remington is the owner of Rich Software Inc, a small consulting firm that specializes in building ESB/SOA software solutions based on Mule as well as developing web applications for its clients. Rich has over 25 years experience in software development including over 10 years experience architecting and developing Internet based applications, including a Java message oriented middleware application. Additionally, Rich has provided onsite Java and web development training for various companies as well as taught C programming courses (when C programming was in vogue) for the University of Denver, Great West Life, CAP Gemini America, and Information Handling Services. He is an innovative and strategic thinker, finding ways to improve information systems, workflows, and business processes - especially across the enterprise.

7:30-9:00PM: How to stop waiting for build/deploy and enjoy coding again

25 percent of developers say that their JEE projects take over two minutes to deploy, every time they want to see their changes. Over 70 percent say it takes at least a minute.  Since on average we deploy five times an hour, we are watching the logs roll by, or switching to email and losing focus, for 10-40 minutes every day.

In this talk, Jevgeni Kabanov will highlight three key techniques that you can start using immediately to drop the time from hitting Ctrl+S to refreshing your browser -- down to less than one second. We will start by discussing exploded development and some shortcuts you can take to eliminate the build scripts from your everyday life. Then we will review some ways to bypass or speed up redeployment. We will take a look at JEE redeployment, OSGi modules, special framework support that exists in Grails, Seam, Tapestry5 and RIFE, and JVM HotSwap. We will cover what you can do for free, and introduce a class reloading JVM plug-in called "JavaRebel", that solves the problem for peanuts.

After this talk, you will leave with a clear idea of at least three ways to reduce your turnaround, and measurably save your team at least an hour per day.

6:00 - 7:00 PM:  GIT control of your source by Stuart Halloway

Git is not the next step in evolution of centralized source control, following in the footsteps of cvs, svn, etc. These tools provide centralized history of deltas, where git provides distributed history of trees of content. 

In this talk, you will see the advantages of the git approach: Incredible speed. Local, disconnected operation. Source control workflow customized to your team. Centralized, distributed, or layered, you can build it with git. Cheap and easy branching, tagging, and merging.

7:30 - 9:00 PM: Programming Clojure by Stuart Halloway

Find out why Clojure is Java.next:

• Clojure provides clean, fast access to all Java libraries.
• Clojure provides all the low-ceremony goodness you know and love from dynamic languages such as Ruby and Python.
• Clojure includes Lisp's signature feature: Treating code as data through macros.
• Clojure's emphasis on immutability and support for software transactional memory make it a viable option for taking advantage of massively parallel hardware.

Clojure is a dynamic programming language for the Java Virtual Machine, with a compelling combination of features:

• Clojure is elegant. Clojure?s clean, careful design lets you write programs that get right to the essence of a problem, without a lot of clutter and ceremony.
• Clojure is Lisp reloaded. Clojure has the power inherent in Lisp, but is not constrained by the history of Lisp.
• Clojure is a functional language. Data structures are immutable, and most functions are side-effect free. This makes it easier to write correct programs, and to compose large programs from smaller ones.
• Clojure simplifies concurrent programming. Of course, Java itself has pretty good concurrency support. But, there is wide agreement that lock-based concurrency is dif?cult to use correctly. Clojure provides alternatives to lock-based concurrency: software transactional memory, agents, and dynamic variables. 
• Clojure embraces Java. Calling from Clojure to Java is direct, and goes through no translation layer.
• Unlike many popular dynamic languages, Clojure is fast. Wherever you need it, you can get the exact same performance that you could get from hand-written Java code.

About Stuart Halloway

Stuart Halloway is the CEO of Relevance, Inc. (www.thinkrelevance.com). With co-founder Justin Gehtland, Stuart helps companies adopt agile, as well as innovative technologies such as Clojure and Ruby on Rails.

7:30 Database Refactoring With Liquibase

You're good at building applications, and you impress DBAs with your relational database designs. Your schemas are flexible, expressive, and performant—but not even you get it right on launch day. If you don't have a way to manage changes to your database, it will soon become mummified, cursing your application with declining performance and ugly hacks for the rest of its life.

 6:00 PM   Lizard Brain Web Design  - by Scott Davis

---

"There’s an old story about the person who wished his computer were as easy to use as his telephone. That wish has come true, since I no longer know how to use my telephone." (Bjarne Stroustrup)

The "lizard brain" is the oldest part of the human brain -- the part responsible for autonomic functions like breathing, heart rate, and navigating websites. OK, maybe not that last part, but your website should be easy to use. Stupid easy. Lizard brain easy. Any time your user spends figuring out how to do something -- even for a split second -- is wasted time due to poor design. Inspired by Steve Krug's book "Don't Make Me Think", this talk answers the question, "Why is that website so hard to use?"

In this talk, we look at what make a "good" website "good". Simple changes in the layout or sort order can yield drastic improvements. We'll get inside the heads of typical users and see how their view of our website is drastically different than what we painstakingly planned out. You'll learn how to cater to "Browsers" and "Searchers" -- the human kind, not the software kind. "Lizard Brain Web Design" answers these questions and more in a funny and informative way.

7:30 PM - DSLs in Groovy: Say What You Mean, Mean What You Say  - by Scott Davis

---

"Simplicity is the ultimate sophistication." (Leonardo da Vinci)

The history of computer programming has been bridging the gap between what the user says ("We need to add sales tax to each item in the order") and what the programming language requires you to say ("for Iterator i = orderList.iterator();"). Building Domain Specific Languages (DSLs) allow you to express the solution in the language of the domain user instead of the language of the programmer.

DSLs can be written in any programming language, but the more flexible the programming language used, the closer to plain English the DSL can be. Groovy is a dynamic language for the Java platform that is ideally suited for creating DSLs. Come see how Groovy can leverage the power of Java in a way that your users might actually be able to read and understand.
