Sessions at ConFoo 2012 on Wednesday 29th February

Nowadays many modern web applications are solely relying on JavaScript to render their frontend and only provide an API endpoint at their backend, resulting in a much more fluent and desktop-application-like user experience. But if you want to create mashups, load data from many different places or include external widgets into your site, you are quickly running into boundaries because of browser and security restrictions. In this presentation I will talk about techniques, some older, some brand new which will help you to:

• create rich JavaScript based Web Applications
• make API calls to external domains
• authenticate these calls through OAuth2 without compromising your secrets
• load external content and JavaScript widgets safely
• send JavaScript messages between frames on different domains
• get real-time notifications from your backendand use the browser to store the some of the user's data.

Until recently, the only way to provide integration between a website and a voice-call and a website was with expensive enterprise software. With new services such as Tropo and Twilio, any web developer can integrate a web application with telephone services. We will walk through using these services to initiate phone calls with our users, automatically ask questions and store answers, verify users phone numbers, and allow users to access web services, their account and data by picking up their phone, calling your web service and requesting data.

This talk will walk through real world examples showing how you can quickly and easily integrate with real time voice calls with your users - pushing the boundaries of the web!

At Smith Electric Vehicles we process billions of pieces of data every week into our telematics system, all coming from remote collection devices continually sending us data. With that data, we need to be able to continually add it to our database, report against it, display recent data, maintain it, and most importantly - ensure we receive every byte of data. No easy challenge!

This talk will discuss some of the concepts, tools and technologies available to help deal with continually processing and managing data through heavily de-coupled systems. From the services needed to ensure you can safely perform maintenance without loosing data, to reporting, storing, managing, displaying and reacting upon this data from within your web application, your database systems while keeping your hair in the process.

MongoDB’s architecture features built-in support for horizontal scalability, and high availability through replica sets. Auto-sharding allows users to easily distribute data across many nodes. Replica sets enable automatic failover and recovery of database nodes within or across data centers. This session will provide an introduction to scaling with MongoDB by one of MongoDB’s early adopters.
