This presentation discusses Hypertable, an open source, high performance, distributed database modeled after Google's Bigtable. Doug discusses the differences between Hypertable and traditional database technology, support for massive sparse tables, scaling to petabytes size, and how Hypertable is designed to run on top of an existing distributed file system, such as the Hadoop DFS.
This presentation covers coaches, coaching, and how the two work together to help guide larger project communities and large agile adoptions. The session also discusses a bit on coaching in general as well as how coaches and managers can (and do) work together to consistently produce better software.
Venkat Subramaniam explains what DSLs are good for, then he demos the creation of a DSL in Java, starting with a grammar and a parser, with an emphasis on useful patterns to be used along the way.
This presentation examines the properties that make Erlang a great language for building Domain Specific Languages. - powerful parsing capabilities, runtime evaluation, and pattern matching are a few covered in this session. Along the way you may learn a thing or two about functional and concurrent programming.
Don Syme presents F# basics, a typed functional language for .NET that combines the succinctness, expressivity, and compositionality of functional programming with the runtime support, libraries, interoperability, tools, and object model of .NET.
In this talk, Dan contrasts the traditional top-down and bottom-up approaches with a proven "outside-in" approach based on real life experience - engaging with and listening to our stakeholders. He shows how this can allow us to stay firmly on track, leading to clean code and effective design that provides maximum value to our stakeholders, not just the famous Scrum Product Owner
"Being Agile" is a state of mind achieved when the practitioner has transcended Agile practice (phase three of agile according to Kent Beck).

Along the way he asks: Is coupling really so bad? Why is REST popular? Do we need distributed transactions?
Scott Stanfield, CEO of Vertigo, presents the Hard Rock Memorabilia web site containing pictures with 200 Mp resolution and how one can zoom in to see very fine details using Silverlight’s Deep Zoom. He also shows other projects to underline some of the Silverlight’s capabilities.
Paul Hudak explores the question whether the elegance of functional programming is a good match for the aesthetics of art? Is it possible that artists could benefit from using functional languages in their work? In addition to the creative process, can functional languages assist artists in other ways? We will explore many of these issues in the context of the visual, musical, and performing arts.
Erlang is built on 3 components: language, OTP, and VM.
