API the Docs Recap

Hi, my name is Serizawa and I’m a technical writer in LINE. LINE has a program that allows engineers to attend overseas conferences on company expense so that they can grasp the latest technology trends. In this article, I’d like to share my report on API the Docs, the API documentation conference that I attended, thanks to the program.

Osaka Developer Meetup 3/30 – Mobile

My name is Parth Upadhyay and I’m a Server Side Engineer on the LINE Shop Team, currently working in Fukuoka. I had the chance to attend our most recent Developer Meetup in Osaka, see some presentations by LINE Engineers, and connect with the developer community there. Today I’d like to share some of what was discussed and my general impressions from the meetup.

Session Overview

The theme of this meetup was mobile, and we had engineers from across the stack give presentations about things they have been exploring or working.

Sending notifications to Clova devices with IFTTT

Here is our first post on Clova after its release. Today, I’d like to talk about integrating Clova with IFFFF which allows us to do things like sending a notification to Clova devices when a new post is uploaded on the LINE Engineering blog. Before we start, let us find out what IFTTT is first.

At the time of posting, the service introduced here is only available in Japan.

Floor map management system on web, with Leaflet

LINE Japan’s office relocated in April, 2017 to JR Shinjuku Miraina Tower to accommodate its growing number of staff. At the time of relocation, the IT support department introduced a number of new systems into the company. One of those is the LINE Floor Map system which I am going to share with you in this post.

Background story

Before we moved to Shinjuku, we used to manage our floor map with Microsoft Excel. Here is a part of the excel file. (We’ve erased names off from the screenshot.)

[Event Report] LINE Fukuoka Developers Host Hackathon

Held for the first time in 2016, the immensely popular Hackathon—held by the engineers in LINE Fukuoka’s Development Department— recently came to a close. Just like its inaugural event, many of the engineers enthusiastically took part in this occasion. They were given a time frame of two days each to develop and present their ideas, and the final demonstration took place in Beppu of Oita Prefecture, which is well-known for its Jigoku Meguri (Hell Tour) and onsens (hot springs). The engineers achieved the feat of transforming all 16 ideas into prototypes despite the tight two-day development schedule. Nagashima-san, an intern for the LINE Fukuoka Data Analytics Team, brings us this report on the Hackathon.

The majority of demonstrations revolved specifically around new technologies: drone programming, AR/VR, Blockchain, big data analysis, and image recognition. It was a potent reminder of the engineers’ insatiable sense of curiosity for anything cutting-edge, and their capacity to efficiently implement new technology. Also, every concept was not just technologically stirring, but simply enjoyable to watch in action, which was clear from the constant laughter from the audience.

Introducing Developer Relations team

This is Kushii from the Tech PR team at LINE. Some of you may already know me for running the Japanese blog. I’ve recently become a member of the Developer Relations team which was set up not so long ago. I wanted have an opportunity to introduce the team to you, so here we go.

LINE x Amazon: Technical discussion

We recently had a technical discussion with Amazon at their HQ, Seattle. Fifteen Liners from Planning, Sales, Development and Evangelism participated in the event, and I participated as a facilitator. My guess is that you’d want to find out what discussed, but unfortunately, all I can share with you for now is the non-technical aspects of the trip. So, I’ll briefly share some of the pictures.

Bot Designer for previewing conversation with chatbots

Bot Designer is an application which allows you to simulate and preview a conversation with a chatbot.

With the LINE Messaging API, you can make a bot send various types of messages such as texts, images, stickers, locations to a LINE user. To check how these messages are actually displayed on the LINE app, what you had to was to create a JSON object representing the message, call the Messaging API, and then check the sent message on the LINE app. Now, with Bot Designer, you can do it by simply entering information in the input fields of Bot Designer which automatically converts the information into JSON objects and renders message previews. You will get the idea right away when you watch the following video clip.

The structure of the LINE LIVE’s encoder layer

On December 10th of 2017, we celebrated our second anniversary for LINE LIVE, our live streaming service. The service has been up and running ever since the launch with no trouble, thanks to the efforts put in by countless engineers at LINE. On this blog post, as a member of ITSC, a team at LINE running a global infrastructure system, I’d like to share with you some of decisions we had to make in the initial phase of designing and implementing the system. Back then, I had absolutely no experience in building or running a live media service.
