  • LINE x Amazon: Technical discussion
    Sho Tachibana 2018.03.16

    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.

  • The structure of the LINE LIVE's encoder layer
    Suhyuk Kim 2018.03.06

    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.
