LINE DEVELOPER DAY 2017 B-1
"In this session, we unveil 'Central Dogma', LINE's textual service configuration repository with multi-master replicated high-availability and version control, based on Git, ZooKeeper and HTTP/2.
Find out what features Central Dogma offers and how they changed the way we work from both engineering and workflow perspective."
LINE DEVELOPER DAY 2017 B-6
"Since web UI integration test takes time on implementation, execution, and maintenance; we parallelized test suites with scalable test executors in CI pipeline.
With containerized test executors, the test suites can be executed on any platforms without library dependencies. To perform a parallel execution, we used docker-based Selenium grid - Zalenium to scale nodes dynamically.
In this talk, we will show the architecture of testing with Docker containers and demonstrate how we make Selenium test faster and flexible in CI."

It's been approximately two years since LINE Login was opened up. Much like last year's LINE Developer Day, we are excited to announce some of our latest features that we recently added to the platform, as well as new soon-to-be-added features. I will also elaborate on the technical aspects of LINE Login.
LINE DEVELOPER DAY 2017 B-7
Our latest app, Creators Studio, lunched in June 2017. With Creators Studio you can easily create, manage and deploy your own Sticker Sets to the Line’s Sticker Store. To create a Sticker you can use your own picture. Just trim out the part you are interested in, add some additional effect and you are done. We tried to make the trimming part as easy as possible. In this talk I will give you an inside view about how this feature works.
LINE DEVELOPER DAY 2017 B-2
Currently we are working on the development of new platform for LINE Game, Topping. It enhances the user experiences on LINE Game with many game-oriented functions, such as in-game chat, in-game BBS, virtual graphs and so on. Today, we will speak about how we've tried to manage and process various game data generated within our platform. In particular, we will focus on two specific topics: time-series data processing with Elasticsearch and multi-row transactions on HBase.
Data analysis for security The log analysis platform Monolith and spam count...LINE Corporation
LINE DEVELOPER DAY 2017 A-9
"We will discuss two case studies for data analysis conducted by the LINE Security Department.
The first use-case is explanation of how we acquire system logs pertaining to the infrastructure (servers, PCs, and the network), the system that quickly detects unauthorized access, heavy loads, information leaks, and other incidents, and the structure of the platform.
In the other, we will discuss the current status of spam countermeasures on LINE and the anti-spam system that analyzes spamminess and automatically blocks based on user reporting data."
LINE DEVELOPER DAY 2017 B-4
This summer, LINE added a PIP feature to show a chat videos and YouTube in a small overlay so that users can watch videos while having fun in chats and on Timeline. I will discuss this implementation and summarize some of the issues we encountered along the way.
Paying back technical debt - A case study of LINE Android client -LINE Corporation
LINE DEVELOPER DAY 2017 A-4
The LINE Android Client is now entering its seventh year of development, and over that time the client implementation accompanying the growth in the service has gotten bloated and become all the more complicated. In order to allow for sustained development going forward under these circumstances, you need to simultaneously move forward with function implementation and repaying technical debt. During this speech, I will discuss what kind of improvements we have made through focusing on code, CI (continuous integration), and team in our efforts to create an environment that can more easily repay technical debt.
Kafka Summit SF 2017 - One Day, One Data Hub, 100 Billion Messages: Kafka at ...confluent
LINE is a messaging service with 200+ million active users. I will introduce why we feed 100+ billion daily messages into Kafka and how various systems such as data sync, abuse detection and analysis are depending on and leveraging it. It will be also introduced how we leverage dynamic tracing tools like SystemTap to inspect broker’s performance on production system, which led me to fix KAFKA-4614.

Surviving in a microservices environmentSteve Pember
Many presentations on Microservices offer a high level view; rarely does one hear what it’s like to work in such an environment. Individual services are somewhat trivial to develop, but now you suddenly have countless others to track. You’ll become obsessed over how they communicate. You’ll have to start referring to the whole thing as “the Platform”. You will have to take on some DevOps work and start learning about deployment pipelines, metrics, and logging.
Don’t panic. In this presentation we’ll discuss what we learned over the past three years. We’ll examine what a development lifecycle might look like for adding a new service, developing a feature, or fixing bugs. We’ll dive a bit into DevOps and see how one will become dependent on various metric and centralized logging tools, like Kubernetes and the ELK stack. Finally we’ll talk about team communication and organization... and how they are likely the most important tool for surviving a Microservices development team.

Should you use Java or JavaScript to write XPages applications? The answer is yes. XPages facilitates creating great applications written almost entirely in Java and written almost entirely in JavaScript. There are no right or wrong answers, only circumstances and ramifications. The determining factors as what is best for your development team are many and complex. In this presentation Andrew will seek to dispel the myth that there is even a competition. The answer should always be - it depends. Come and see the session and make your own mind up.
Scaling Scrum with UX in the EnterpriseCaleb Jenkins
Scrum is the most popular Agile framework in the world for effective team collaboration on complex projects. Scrum provides a small set of rules that create just enough structure for teams to be able to focus their innovation. Scrum is optimized for teams for teams of 5 to 9 people. Making Scrum work with larger teams or in large enterprise environments brings its own set of challenges. This talk presents 3 patterns used on enterprise teams to scale Scrum effectively with global teams.
This presentation was given at the 2014 Tulsa Tech Fest in Tulsa, OK - http://developingux.com/TulsaTech2014/

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
