The pitfalls and how to avoid them and how to get other organisations involved so everybody wins. With less money for education in most company budgets, community events are often the fastest and most cost efficient way to learn and share.

We are always in a continuous product improvement cycle heavily influenced by these experiments and corresponding data.

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.

Learn why it chose Java EE, and hear about its experiences and lessons learned. This is the first time a large credit card company in Japan is sharing its story. How do you start such a big project? Why did it choose Java EE? How did it select the in-house development policies, educate itself, and develop the additional libraries? How did it launch within only six months? What is the key factor driving 24/7 critical financial systems successfully? How do you migrate to Java EE 7 in the future? This presentation answers these questions and any others you may have.

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.

35 students worked overnight in groups, to develop applications using Rakuten APIs. The top 2 teams will perform presentations at the conference on what they have accomplished during this two-day hackathon.
Let's hear these energetic presentations from our young students!
Team: KUNL “Sonoba-de-recipe”
This creative application is useful when you need to prepare something delicious but you have no idea how to cook or what ingredients you should use. The application analyzes a given picture and returns the best-matched menus using Rakuten APIs.
Team: Miyako-Airline “Gra-navi”
Gra-Navi visually displays Rakuten Travel's map using animations so users can compare hotels and navigate through a location map on a single view.

Linux Containers are a lightweight form of virtualization that provides some advantages over traditional Virtual Machines with the same portability and repeatability guarantees. But how do you run them in production? In this talk Nathan LeClaire, a Solutions Engineer at Docker, Inc., will teach you the details of running Docker in production systems. Topics covered will include service discovery, orchestration, image distribution, and more.

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.

Under the hardware of the same number of CPU cores, the same amount of main memory and the same amount of Disk storage, OoODE succeeded to boost the performance of database operation around hundreds and thousands of times. Hitachi deployed our technologies in their RDB product.OoODE can improve the performance of RDB on Flash and Hive on Hadoop.

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.

Generally, we will check it only near release schedule. It's so good, but it's not best. Recently, we are only using some CI Tools for application tests and deployments. But, I think that we must always do security checking which is as a part of Continuous Integration. Therefore we will get knowledge and knowhow of OSS Security Check Tools and Communities as one of the way to do that. So, I introduce you to several kinds of OSS for security checking and our new SaaS, Walti.io.
