Want to write Node.JS applications and want someone to show you the ropes? In this workshop we will go through a quick paced introduction to node.JS, and will introduce the basic principles of writing evented IO applications. For the more advanced developers it will be interactive on the depth of certain subjects.

Event-based I/O with JavaScript on embedded Linux provides single-language development of web-based visual monitors and controls with a broad range of sensors and actuators. Simple open hardware and software examples enable rich, affordable collaboration upon Linux. Connecting various sensor types, building Processing.JS-based visualizations and sharing your creation are also covered.

Are you building a big app, and wondering why NodeJS backends scale so well for applications? At Cloud9 we have built our entire backend in Node.JS, and it has taught us a lot of lessons. In this presentation i want to go through what we learned at Cloud9 IDE also want to give attention to common pitfalls and tracing bugs.

Nowadays many modern web applications are solely relying on JavaScript to render their frontend. 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 helping you with such problems.

Today's web and mobile apps ever more personalized with increased reliance on server side APIs. But data retrieval from servers slows down developers and users due to code complexity, latency, low-resiliency, and bandwidth use. In this talk we'll show how ql.io, a node.js based HTTP gateway from eBay, can accelerate HTTP API programming to boost performance and user experience.

While dynamic languages are extremely popular for rapid development, they're notoriously difficult to debug in production. Despite being a relative newcomer, Node.js has already developed sophisticated tools for both postmortem and runtime analysis that exceed those of many popular languages. We will discuss our work building and deploying such tools, including real-world production experiences.

Learn how to make beautiful, fast, and interactive maps for web and mobile using the latest open source tools. Technologies discussed will include Node.js, Mapnik, TileMill, MapBox, CartoDB, and TileStache. TileMill wil be the central tool used for hands-on learning. We will showcase how both technical and non-technical users can turn raw data into hosted and embeddable maps.

You package your assets. You use CSS sprites. You serve up everything with gzip compression. You obsess over Yslow recommendations. But you are still not SPDY. Fundamental limitations in HTTP and TCP/IP still add up to 60% overhead to your site. Find out how to reclaim that lost bandwidth and increase the robustness of your sites at the same time.
