Python Utilities for Managing MySQL Databases
by Charles Bell and Mats Kindahl
Managing a MySQL database server can become a full time job. What we need are tools that bundle a set of related tasks into a common utility. While there are several such utility libraries to choose, it is often the case that you need to customize them to your needs. The MySQL Utilities library is the answer to that need. It is open source so you can modify and expand it as you see fit.

Structural Prototypes: Resolving the Statically-typed Object-functional Dichotomy
Object-functional languages have a number of desirable properties and have proven very useful in practice. Unfortunately, the merger brings with it a raft of complexities, being the root of nearly all of Scala's infamous complexity. This talk will present a new framework for resolving these issue, based around the notion of statically-typed functional object prototypes.

CouchApps with CouchDB, JavaScript & HTML5
by Bradley Holt
CouchApps are web applications built using CouchDB, JavaScript, and HTML5. CouchDB is a document-oriented database that stores JSON documents, has a RESTful HTTP API, and is queried using map/reduce views. This talk will answer your basic questions about CouchDB, but will focus on building CouchApps and related tools such as: couchapp, a command line tool used to generate code templates and push CouchApps to CouchDB instances; Evently, a jQuery library used for writing JavaScript applications; CouchDB API, a jQuery library that abstracts access to CouchDB’s core API; CouchApp Loader, used to load design document classes into JavaScript applications; Pathbinder, a JavaScript framework that triggers events based on URL hashes; and Mustache, a JavaScript templating framework.

Crunching the numbers: Open Source Community Metrics
by Dave Neary and Dawn Foster
Every community manager knows that community metrics are important. But they all have their own set of hacky scripts for extracting data from various tools. Building on the work of Pentaho, Talend, MLStats, gitdm and a host of others, we built a generic community dashboard for the MeeGo project. This presentation will cover the data we extracted, how we did it, and how you can do it too.

Stratos - an Open Source Cloud Platform
Cloud is the biggest user of Open Source, but also a threat - people are building their apps on Cloud Platforms that are closed. Stratos is an Apache Licensed project for a Cloud Platform-as-a-Service. We will take a deep dive into this multi-tenant, elastic, metered cloud runtime that includes Tomcat, ESB, Registry and more. This will be a detailed session aimed at developers and infra experts.

Big Data; Small Problems (And a Tale of Two Sequels)
by Tim Anglade
A look at the state of data storage, management & analysis, from SQL to NOSQL, “NewSQL” and beyond. I will explain why the core premises of data management have changed; tell some of the tales of success and failure I have collected on the topic; share some counterintuitive rules-of-thumb about the sometimes mind-blowing, sometimes nerve-wrecking reality of life with an alternative datastore.

Building a Hacker Culture: Uruguay's Laptops and Broadband for All
by rabble
What does it take to build a hacker culture? This talk will cover activities in creating a hacker society in Uruguay. The small south american country has engaged in the massive task of raising a generation of hackers. Every school child gets an XO laptop and every landline comes with DSL. While most of the world is trying to replicate silicon valley, Uruguay's building something quite different.

Freeing the Cloud, One Service at a Time
As more and more computing moves into someone else’s data centre (i.e. the Cloud), users and companies are losing direct control over their data and processes. The risks they used to be able to mitigate by using Free and Open Source software are starting to become apparent.
So what can be done to continue to enjoy the software freedom that we have come to appreciate in the desktop computing world? Just like the task of building a completely FOSS operating system in the 1980s looked like an impossible dream, having a completely free online life appears to be quite a big task. Thankfully, many people are now tackling this problem and starting to build freedom-respecting options, one service at a time.
This talk will discuss an approach to building free network services and introduce Libravatar, a Django based project to provide a federated alternative to the Gravatar profile image hosting service, a centralised web service used by a very large number of social sites around the world.

Open Source Identity With No Lock In
by Simon Phipps and Lasse Andresen
Most open source start-ups have some sort of lock on the code - dual licensing, contributor agreements, "open core" add-ons and more. But is it possible to start a profitable company without any of those - with just skilled people delivering expert service and developing new code in the community? I don't just think it's possible - I'm doing it!

Shield Your LAN with sshGate
This talk focuses on building an SSH proxy which shields the remote targets from the users by hidding their specific credentials. Using an unpatched openssh on any UNIX flavor, sshGate provides an administration CLI, ACLs, groups, and logs users' sessions, which can be replayed anytime later. Users can use any standard ssh clients, and no installation is required on the managed targets.

Connecting iOS to the Real World with Arduino
by Alasdair Allan and Brian Jepson
Modern smart phone platforms, like Apple’s iPhone, come with a growing range of sensors; GPS, accelerometers, magnetometers and more recently gyroscopes. They also have a (near-)ubiquitous data connection, whether via a local wireless hotspot or via carrier data, and user positioning via multiple methods including GPS.
They would make an excellent hub for a distributed sensor network. However it is actually quite difficult to interface these otherwise interesting devices using standard serial devices. In the case of the iPhone the proprietary dock connector is a major stumbling block. During this session we will present several different methods which will allow you to connect any iOS device to an Ardunio, or in some case directly to an XBee mesh-network.
We will first discuss the official route, using the MFI approved Redpark serial cable, this makes use of Apple’s own External Accessory Framework. Whilst the most expensive route, it is also the simplest. However in addition to this we will go on to discuss using the headset interface to enable communication with external serial devices, this is a fairly well trodden route with several well known examples such as the Square credit card reader. Finally we will look at more off-the-wall routes such as repurposing the official MIDI interfaces, as well as the ANT+ protocol.

Ensemble And The Art Of Service Orchestration
by Clint Byrum
Is anybody else tired of hearing about the Cloud? Sick of hearing about how its going to change everything and how it can scale infinitely and that it makes the best Belgian waffles you’ve ever had.
Whats missing, the reason you don’t have your waffles yet, is a way to tie it all together in a way that makes sense. We’re still hitting the cloud screw with a server hammer, and wondering why its not very satisfying.
Ensemble is a new model, with an implementation, for service orchestration on top of Ubuntu. Bring up existing best of breed open source technologies, plug your app into them rapidly, and scale easily.

Open Source Preventive Medicine: Citizen Science Genomics
by DIYgenomics
Preventive medicine is a grand challenge. A key step is establishing baseline markers of wellness and pre-clinical interventions using personalized genomic data and phenotypic data. DIYgenomics has created such a methodology and completed a MTHFR/Vitamin B deficiency pilot study. An aging study is in enrollment, and other studies are in design for Vitamin D, metabolism, and mental performance.
