Apache CouchDB can serve complete web apps, without a middle-tier application server. Because these apps can be deployed to any running CouchDB node (including user's local machines), they present potential for end-user innovation, but because of view source but also through peer based replication. We'll learn to use the CouchApp JavaScript and HTML framework to build sharable applications.

Internet traffic spikes aren't what they used to be. It is now evident that even the smallest sites can suffer the attention of the global audience. This presentation dives into techniques to avoid collapse under dire circumstances. Looking at some real traffic spikes, we'll pinpoint what part of the architecture is crumbling under the load; then, walk though stop-gaps and complete solutions.

Abstraction is a powerful servant, but a dangerous master. We code, design, think, debug ... on a tower of abstractions. Spolsky's Law tells us that "All abstractions leak". This talk explores why they leak, why that's often a problem, what to do about it; I also cover why sometimes abstractions SHOULD "leak", and how best to produce and consume abstraction layers.

YAML is the serialization language that enables sharing of complex data between Perl, Python, Ruby, PHP and Java. It does it so in a human friendly manner. Many popular frameworks use YAML, including Ruby on Rails.
In this talk, Ingy döt Net, one of the authors of the YAML specification, will show you how to share data objects not feasible by JSON or XML.

The age of Big Data demands open-source tools that move beyond storage towards analytics: tools to turn terabytes into insights. R is an open-source language for statistical computing and graphics, and an extensible, embeddable tool for the analysis of large data sets. In this session, I showcase R's power by building predictive models for Brazilian soybean harvests and baseball slugger salaries.
