Presentations
Pair Programming for the Single Programmer
The full title of this talk is, "The Sound of One Hand Clapping, or How to Pair Program with a Single Programmer -- Scaling XP to Small Projects." Everyone talks about using J2EE for massive projects, but what about the lone wolf developer? Can they still apply the lessons learned from agile development methodologies to their everyday work?
XP is an ideal methodology for dealing with small business owners and entrepreneurs. Often times small projects suffer from the complete lack of good programming practices because heavy-weight methodologies don't scale down well. Heavy-weight methodologies can also be intimidating to the non-computer professional. XP scales well to small projects and allows the domain experts to participate in good programming practices (sometimes for the very first time).
Guerrilla Web Techniques
Frameworks? We don't need no stinkin' web frameworks. OK, so maybe that's overstating the case. Web frameworks do plenty of good things, but sometimes they can also be golden handcuffs. Too many web developers fall into the trap of thinking, "If it can't be done by my web framework, then it simply can't be done."
This presentation focuses on the cool things that you can accomplish by stepping out of your web framework and getting closer to the underlying technology. We'll take a detailed look at what really goes on during the request/response cycle, and how new techniques like AJAX allow you to break the mold. We'll look at the clever things you can do with MIME types, User-Agents, and HTTP Headers in general.
Old technologies like CSS, DOM, and JavaScript are experiencing a renaissance under the guise of new names like DHTML and AJAX. Google Maps and GMail are literally redefining our expectations of how rich a web application can be by using these technologies to their fullest potential. Come see what makes these sites tick, and how you can utilize the same techniques in your own site.
Testing the Web Tier
Hopefully your test plan involves more than, "Well, it compiled..." JUnit is fast becoming a required part of the modern Java developer's toolkit. Unit testing your Java classes is a great start, but your test plan shouldn't stop there.
This talk will introduce several additional testing tools for the web developer -- HttpUnit, Canoo WebTest, and JMeter. These tools allow you to test a live website with no changes to the production code. Even better, you can test sites that have been implemented in technologies other than Java.
You will see code examples and live demos of these tools in action. We'll talk about the differences between unit testing, functional testing, and performance/load testing. Come get "test infected" -- you'll never look at the development process the same way.
Testing the Web Tier, Part 2
JUnit is more than a Java testing tool -- it is a testing framework that can be extended to test non-Java resources as well. In the first presentation in this series, we examined three JUnit extensions that allow you to functionally test your website. In this talk, we'll look at three more tools that web developers should have in their toolkit: JsUnit, DbUnit, and the W3C Markup Validation Service.
JsUnit allows you to test your JavaScript. Anyone who has done JavaScript development knows that cross-browser support of JavaScript is a tricky proposition. Rather than emulating a specific browser, JsUnit can literally launch different browsers and execute the test suite to ensure that the JavaScript code you wrote actually works.
DbUnit allows you to stage your database tables for unit testing purposes. You can insert and delete information as a part of your test suite. While the database isn't technically a part of the web tier, we'll show how the proper use of this tool allows you to test the other parts of the web tier with ease.
HTML compliance is difficult if not impossible to see just by looking at raw HTML. Browsers are reasonably permissive in terms of the HTML they'll render, but writing valid HTML ensures the widest possible audience for your site. We'll show you how to incorporate this free online service with JUnit.
Real World Web Mapping
In this presentation, we'll explore the top four mapping sites and show you how to take advantage of their free services. MapQuest, Yahoo Maps, Google Maps, and MSN Virtual Earth all bring slightly different capabilities to the table. These sites allow you to create your own interactive maps with minimum effort and no previous mapping experience. They take care of hosting the mapping data and making it easy to manipulate -- all you have to do is bring a little bit of know-how to the party.
Thanks largely to Google, web mapping is experiencing a renaissance. Google's mission statement is, "... to organize the world's information and make it universally accessible and useful". They aren't specifically talking about web mapping, but the sentiment certainly applies. If you have data that naturally has a geographic element (a customer list with addresses, sales reports by regions, even a collection of favorite restaurants), today's websites make it easier than ever to display them on a map.
Even if you aren't specifically interested in creating your own maps, this presentation gives real-world examples of many industry hot-button topics -- SOAP vs. RESTful web services, JavaScript and AJAX, and a clear distinction between first generation web technology (Web 1.0) and what the pundits are calling "Web 2.0".

Each recipe in Groovy Recipes begins with a concise code example for a quick start, followed by in-depth explanation in plain English. These recipes will get you to-to-speed in a Groovy environment quickly.
You'll see how to speed up nearly every aspect of the development process using Groovy. Groovy makes mundane file management tasks like copying and renaming files trivial. Reading and writing XML has never been easier with XmlParsers and XmlBuilders. Breathe new life into Arrays, Maps, and Lists with a number of convenience methods. But Groovy does more than just ease traditional Java development: it brings modern programming features to the Java platform like closures, duck-typing, and metaprogramming.
As an added bonus, this book also covers Grails. You'll be amazed at how quickly you can have a first-class web application up and running from ground zero. Grails includes everything you need in a single zip file⎯a web server (Jetty), a database (HSQLDB), Spring, Hibernate, even a Groovy version of Ant called GANT. We cover everything from getting a basic website in place to advanced features that take you beyond HTML into the world of Web Services: REST, JSON, Atom, Podcasting, and much much more.

There is a hidden revolution going on: geography is moving from niche to the mainstream. News reports routinely include maps and satellite images. More and more pieces of equipment cell phones, cars, computers now contain Global Positioning System (GPS) receivers. Many of the major database vendors have made geographic data types standard in their flagship products.
GIS for Web Developers introduces Geographic Information Systems (GIS) in simple terms and demonstrates hands-on uses. With this book, you'll explore popular websites like maps.google.com, see the technologies they use, and learn how to create your own. Written with the usual Pragmatic Bookshelf humor and real-world experience, GIS for Web Developers makes geographic programming concepts accessible to the common developer.
This book will demystify GIS and show you how to make GIS work for you. You'll learn the buzzwords and explore ways to geographically-enable your own applications. GIS is not a fundamentally difficult domain, but there is a barrier to entry because of the industry jargon. This book will show you how to "walk the walk" and "talk the talk" of a geographer.
You'll learn how to find the vast amounts of free geographic data that's out there and how to bring it all together. Although this data is free, it's scattered across the web on a variety of different sites, in a variety of incompatible formats. You'll see how to convert it among several popular formats including plain text, ESRI Shapefiles, and Geography Markup Language (GML).
With this book in hand, you'll become a real geographic programmer using the Java programming language. You'll find plenty of working code examples in Java using some of the many GIS-oriented applications and APIs. You'll be able to:
Find free sources of GIS data on the web Browse GIS data using open source desktop viewers Manipulate GIS data programmatically Store and retrieve data using geographically-enabled databases Explore free web toolkits like Google Maps Publish and consume web services using Open Geospatial Consortium (OGC) interfaces
