  • Floor map management system on web, with Leaflet
    Yasunori Iwatsuki 2018.04.03

    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
    2018.03.26

    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.

  • LINE x Amazon: Technical discussion
    Sho Tachibana 2018.03.16

    I am a technical evangelist for the LINE platform, including LINE Messaging API and LINE Login.

    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
    Kazuki Nakajima 2018.03.15

    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.
