Let's invent future
12:00 - 12:45 / Track A / 4F Main Hall
My favorite quote is "The best way to predict the future is to invent it." by Alan Kay.
Stop guessing what kind of features Apple will add to next iPhone.
Instead, come up with a set of features you’d add to iPhone if you were in charge of the development of iPhone. Think what kind of impact you want to give to people’s lifestyle with your next product. Don’t follow the trend; create a new trend.

Why Most Unit Testing is Waste
14:00 - 14:45 / Track G / 14F
Automated unit testing is one of the most popular tools of agile development. While unit tests made sense in the days when a testable unit (a function) was derived from a requirement, they don't make sense in an agile OO world. Yet we continue to use them, partly out of habit, and partly because they're easy and simply because we can, rather than because we should. Many unit tests have no business value and quite a few actually have negative business value. Automation removes the human from the loop; even Toyota is replacing its robots with people to restore learning to the work cell. Instead of unit tests, great products apply the same principles to defensive programming: effectively deliver the tests with the code.

Connecting the real and virtual to combine the benefits of retail and e-commerce
15:00 - 15:45 / Track D / 5F University
Customers use so many computers and portable devices that they now expect always more from the services they get in physical stores. The convergence between e-commerce and traditional retail is already a reality for them, who combine several ways of buying and getting information about products. They go online from home and from stores to compare prices, features, and to order products without waiting in line for payment. They go to real stores to have a physical perception of the products and to avoid waiting for a delivery. We could help them combining the benefits of the different ways of shopping and many technologies and business models are emerging in this domain but no one knows exactly for the moment how use them with success.

16:00-16:20 Leveraging Spark for Cluster Computing: Hadoop's Slope of Enlightenment (Robin Swezey)

In this talk we will introduce Spark, an open-source data analytics cluster computing framework originally developed at Berkeley. Spark builds on top of HDFS, but is not tied to MapReduce. Comparing it to pre-existing Hadoop stacks, we explain how it wins the battle as a framework of choice for both MapReduce-type applications and general cluster computing. We show its simplicity and efficiency, and how it can be leveraged to develop in quick iterations numerous cluster applications such as distributed machine learning.

To achieve this, we adapted a methodology to enhance the productivity and speed of product release.Smart device development is carried out with a small team of members. In each activity, firstly we have realize the division of product into individual modules.Each module is loosely-coupled to run development of various modules in parallel.Next is to assign developer to each module by choosing the appropriate member based on clarification of the functions, specifications in smart device application and reliability on the member. As a result, we could achieve more productivity while developing smart device application.I'd like to explain about our performance enhancement by doing a case study and analysis of our development team activity.Moreover I would like to explain the accuracy and speed achieved b using this approach in our smart device application development.
