Vast Rank is a College Ranking & Review website that makes use of several Google APIs to power its unique set of features. This session will dig into the code behind Vast Rank's "Ranking Map" that provides contextual College Rankings based on what a user has in view on his or her Map. Code examples will be shown utilizing the Google Maps API, the Google Maps Marker Manager, the Google Client Geocoder, and the Google Client Location information exposed by the AJAX API loader. The session will end by discussing future plans to incorporate additional Google API's including the Translation API to translate international content, the Languages API to utilize jQuery, and the Google AJAX Search API to improve the user's search experience.

Recently, Google Data APIs have implemented new technologies in order to make applications and communications with Google Data APIs more efficient. We'll present these new technologies, including ETags, Partial Get and Update, and a new compact JSON format, and show how you can use them to improve your applications. We'll demonstrate these features by showing an example built on top of the Google Photos (Picasa Web Album) API.

Some might think of DataMapper as a better, faster, competitor to ActiveRecord. However, they would be missing on of its greatest strengths. At its core, DataMapper provides a uniform interface on top of ANY persistance layer. All thats needed is a simple adapter class that can translate the native persitance into a simple 4-method API for DataMapper to consume. This talk will cover that API, and some best-practices on implementing an adapter. We will explore the YAML Adapter, which I will be writing for the purposes of this talk.

Amazon subsidiary Alexa.com is leveling the search playing field. For the first time, developers looking to build the next "big thing" in search or an ultra custom search engine have access to the 300 terabytes of Alexa crawl data, along with the utilities to search, process, and publish their own custom subset of the data-all at a reasonable price. Developers no longer need a million dollar budget or to reinvent the wheel designing search algorithms, to be able to build their own search engines or create customized Web services based on data from the Alexa crawl. As a full-service Web analysis and Web service publication platform, the Alexa Web Search Platform should allow any user with an Internet connection to access Web content on a large scale and provide new services or applications to the online community. Jeff Barr provides an overview of the Alexa API and shows developers and designers how to get on the new, leveled search playing field.

Everyone's had the problem of wanting to access and allow access to web services/APIs for extensions and plugins, but this usually means handling login credentials in plain text. Not many users like this, and those that do give their login and password out are compromising their account's security. OAuth is a solution to this. Designed by the people that created OpenID, you can let your users give permission for a 3rd-party application to access their account the same way that services like Flickr do it. Not by using login/password, but by using an encrypted authentication token. Tim will talk about OAuth integration into Rails projects, cover the basics of OAuth for beginners, show how to istall OAuth to protect an existing project, how to protect controller actions with OAuth, and how to accept and use OAuth tokens from other providers.

About Tim
Tim is the Agile Development Director at Cloudspace, an Orlando-based web apps shop. He's been coding for nearly a decade, but unless you're *really* into Firefox Extensions or Twitter, you've probably never heard of him. When he's not writing code for fun and profit, he spends time with his wonderful girlfriend, and aspires to awesomeness on the drums.

HotCocoa is a thin, idiomatic Ruby layer that sits above Cocoa and other frameworks. HotCocoa will be included with MacRuby when it ships in future versions of OS X and is currently included in the MacRuby distributions.

Cocoa classes have extremely verbose method and constant names. A substantial amount of code is written to just instantiate and configure instances of these classes. Interface Builder is used by most developers because it hides the complexity of manually configuring controls, but at the expense have having to use a GUI builder and the obscuring those configuration options inside the IB user interface. One of HotCocoa's chief goals is to allow Interface Builder simplicity, but in Ruby code.

Buttons, Sliders, Windows, WebViews...the whole works...HotCocoa simplifies this process by creating a mapping layer over the top of Objective C classes. HotCocoa adds Ruby-friendly methods, constants and delegate techniques that look refreshingly simple, but do not prevent full use of the Cocoa APIs.

This session will demonstrate the current state of HotCocoa, how to use it to construct full OS X applications quickly, and what our plans are for it in the future.

About Rich Kilmer

We will show you how it's easier than ever before to write your own file systems using the tools and programming language of your choice. Some of the highlights of the talk are as follows.

• How to leverage new features in MacFUSE make your file system act more like a native Mac OS X file system.
• How to use the power of DTrace to debug and analyze your file systems and understand Mac OS X file system behavior in general.
• What the upcoming 64-bit support in MacFUSE means for your file systems.
• How to use the new file system templates in MacFUSE to quickly get started on a new file system.
• How to choose the best MacFUSE API for your specific needs.
• What the most important MacFUSE best practices are and how they can help you write less code that does more.
• Advanced and little known tips and tricks.

You will also get to see some interesting and unusual file systems never seen before on Mac OS X.

Various data mining techniques have been applied to mine source code repositories. However, relying only on one or several local source code repositories may not provide sufficient, relevant data samples (e.g., usage of a certain API call) for mining tasks such as code reuse and defect detection. The recent availability of code search engines allows the mining scope to be scaled to billions of lines of open source code available from the Web, and thus increases the chance of getting sufficient, relevant data samples for mining. This talk will discuss the mining opportunities and challenges based on searching open source code from the Web and present new approaches that mine open source code searched from the Web to assist code reuse and defect detection

The 2nd part of the revision, this time covering the FileSystem API, the Nodes API, and the Explorer & Property Sheet API. You must have watched at least part 4 and part 5 before watching this screencast, because this screencast revises those.

NetBeans internally uses the concept of a virtual filesystem. FileSystem module provide APIs for accessing such virtual files as well as some support classes to make writing of custom vitual filesystems easier.

Nodes API gives you a generic model that is suitable for a number of different Swing components, instead of requiring you to rewrite the model when you switch between different UI components.
