SweatDrops is a social networking app for athletes and fitness enthusiasts. It allows users to find nearby people with similar interests to exercise with, and discover fitness and sports events in their area. The app was built with a Ruby on Rails backend and iOS clients. Key features include displaying nearby users and loading local events from third party APIs into the app's database. The system is centered around events, which users can attend, host, and build their social networks around.

What’s in here?
Just to show a piece of the work we’ve done here:

 What’s the SweatDrops app?
 How it was conceived?
 Two functionalities samples:
 People’s nearby
 Loading fitness/sports events

SweatDrops
 What’s that?
A social network targeted to sportists, athletes and fitness
lovers. For example you can (not limited):
- Find people with you same interests (i.e. someone who may
want to jog with you) and follow them.
- Find events near you (i.e. a Triathlon contest in Miami) and
participate (check in) on those events

App’s function example:
People’s nearby
Want to find somebody around me to run 10 miles in San Francisco?

From the device’s GPS: Lat/Long

Call a secure restful RoR service:

The heart of the system: The
events
 The system is conceived around the events.
 Event examples:
 Marin Count Half Marathon, 10K and 5K
 Zumba class by Mihaela Stanciu at San Francisco
 Let’s job for fun in Lake Merced 3 miles
 Why?
 In this world, you build your network over sports/fitness
events.

How Sweat catches events?
 From the users:

 From third parties via their APIs

Active.com Zumba

MindbodyOnline.com

Catching events from third
parties
 Zumba, active.com and MindBody offer APIs to grab
events from their database
 Using Rails rake:tasks:
 Invoke the webservice
 Insert the events in the database
 Keep track
 Live code for a similar problem:

Provides basic data services like maps, schedules, etc. Transaction: Manages transactional services like reservations, purchases, etc. Location: Tracks locations of users and objects. Controller: Manages the overall system and coordinates between other servers. Database: Stores persistent user profiles, device profiles, content data, transaction state etc. The servers communicate with each other and with the clients over the wireless infrastructure. System Scalability A key requirement for Rover is to scale to a very large number of clients, for example, thousands of users. To achieve this, Rover employs a distributed, concurrent software architecture at the servers. The key aspects are: - Fine-g

The document provides an overview of Robot Operating System (ROS) and demonstrates the Kinect XBOX 360 sensor using ROS. It describes the different levels of ROS including packages, stacks, messages and services. It also explains node communication and concepts like coordinate frames, actions, and plugins. Finally, it gives technical details of the Kinect sensor and demonstrates its capabilities for skeletal tracking and gesture recognition using OpenNI and ROS.

Skeuomorphs, Databases, and Mobile PerformanceSam Ramji

��

The document discusses skeuomorphs and metaphors in architecture and databases. It explores how mobile applications can architect for performance by making the application smarter through profiling, threading, and caching, using the network intelligently through bundling and pipelining requests, and optimizing databases through stored procedures, queueing, denormalization, and managing result sets. The document considers whether describing the internet as a database is a skeuomorph or metaphor, and discusses lessons learned from prior database architectures that can help improve mobile performance.

The document discusses skeuomorphs and metaphors in architecture and databases. It explores how mobile applications can architect for performance when the internet functions like a database. It recommends making applications smarter through profiling, threading, and caching, using networks intelligently through bundling and pipelining requests, and optimizing "databases" through stored procedures, queueing, denormalization, and managing result sets. The document considers whether viewing the internet as a database is a skeuomorph or metaphor, and discusses lessons from the past that can help optimize current mobile and cloud architectures.

RDF Stream Processing: Let's ReactJean-Paul Calbimonte

��

The document discusses requirements and approaches for RDF stream processing (RSP). It covers the following key points in 3 sentences: RSP aims to process continuous RDF streams to address scenarios like sensor data and social media. It involves querying streaming data, integrating streams with static data, and handling issues like imperfections. The document reviews existing RSP systems and languages, actor-based approaches, and the 8 requirements for real-time stream processing including keeping data moving, generating predictable outcomes, and responding instantaneously.

The document describes the Rover technology, which provides location-aware services to mobile users. The Rover architecture tracks user locations using wireless infrastructure and tailors information and services based on each user's location, profile, and device capabilities. It allows large numbers of users to be supported through its action model, which schedules tasks more efficiently than threading. Experimental results show the action model has much lower overhead than a threaded approach. The document also discusses Rover's interfaces, services, and ability to scale to multiple administrative domains.

Mapping mobile roboticsDevasena Inupakutika

��

This document describes a project that uses SLAM (Simultaneous Localization and Mapping) to create maps of an unknown environment using a Turtlebot mobile robot equipped with a Kinect sensor. The GMapping ROS package is used to implement SLAM and build occupancy grid maps while simultaneously localizing the robot. Issues arose from using the Kinect's RGB sensor instead of a laser scanner for mapping. The resulting maps showed the robot's trajectory and obstacles but were less precise than if a laser scanner was used. Autonomous navigation on the created maps demonstrated the basic SLAM approach.

The document discusses APIs and provides examples of RESTful APIs. It describes how RESTful APIs are built upon a domain model to provide resources that can be navigated through requests. This allows clients to construct custom requests to get precisely the data needed, rather than requiring multiple calls or getting excess data. The domain model also provides a unified framework for request and response semantics.

It's about all of us living in a world that is augments by the ambient presence of billions of computing devices. And they're all going to be programming using JavaScript! Well, at least a lot of them will be. In this presentation I'll be discussing how JavaScript is changing the world, and how the world is changing JavaScript..
