Why Visualizing Government Data Makes Taxpayers Happy
by Jeremiah Akin and Michael Castellon
The expectation of transparency is creating demand for government agencies to develop new ways to communicate complex data and trends to the public in easy-to-access and easy-to-understand formats.
Some agencies are turning to Google Maps and KML data to visualize raw information online and on mobile devices. Delivering data in more easily understandable formats not only boosts trust and confidence between government agencies and their publics, but also streamlines workloads among Data, Web, Editorial, and Customer Service teams.
The Texas Comptroller is the state’s chief revenue officer, tax collector, and treasurer. The agency uses public-facing maps to communicate data and economic trends across the state, editorial coverage, and to promote initiatives such as its Unclaimed Property initiative, which works to reunite taxpayers with about $2 billion in unclaimed money and property.
This discussion will focus on how agencies and other organizations can use free or inexpensive tools to deliver data to the public in both traditional online formats and mobile platforms, and how workflows can be arranged so that data visualization can be managed and administered by non-technical staff. We will also discuss how maps can be used internally to enhance strategic efforts.

Solr Power FTW: Make NoSQL Your Bitch!
by Grant Ingersoll and RC Johnson
Solr is an open source, Lucene based search platform originally developed by CNET and used by the likes of Netflix, Yelp, and StubHub which has been rapidly growing in popularity and features during the last few years. Learn how Solr can be used as a Not Only SQL (NoSQL) database along the lines of Cassandra, Memcached, and Redis.
NoSQL data stores are regularly described as non-relational, distributed, internet-scalable and are used at both Facebook and Digg.This presentation will quickly cover the fundamentals of NoSQL data stores, the basics of Lucene, and what Solr brings to the table. Following that we will dive into the technical details of making Solr your primary query engine on large scale web applications, thus relegating your traditional relational database to little more than a simple key store.
Real solutions to problems like handling four billion requests per month will be presented. We'll talk about sizing and configuring the Solr instances to maintain rapid response times under heavy load. We'll show you how to change the schema on a live system with tens of millions of documents indexed while supporting real-time results. And finally, we'll answer your questions about ways to work around the lack of transactions in Solr and how you can do all of this in a highly available solution.

Love, Music & APIs
by Dave Haynes and Matthew Ogle
In the old days it was DJs, A&R folks, labels and record store owners that were the gatekeepers to music. Today, we are seeing a new music gatekeeper emerge... the developer. Using open APIs, developers are creating new apps that change how people explore, discover, create and interact with music. But developers can't do it alone. They need data like gig listings, lyrics, recommendation tools and, of course, music! And they need it from reliable, structured and legitimate sources.
In this presentation we'll discuss and explore what is happening right now in the thriving music developer ecosystem. We'll describe some of the novel APIs that are making this happen and what sort of building blocks are being put into place from a variety of different sources. We'll demonstrate how companies within this ecosystem are working closely together in a spirit of co-operation. Each providing their own pieces to an expanding pool of resources from which developers can play, develop and create new music apps across different mediums - web, mobile, software and hardware. We'll highlight some of the next-generation of music apps that are being created in this thriving ecosystem.
Finally we'll take a look at how music developers are coming together at events like Music Hack Day, where participants have just 24 hours to build the next generation of music apps. Someone once said, "APIs are the sex organs of software. Data is the DNA." If this is true, then Music Hack Days are orgies.
