IoT is the tread of modern living. Every machine we work with, has the tenancy to get connected to the internet for centralized processing and functionality enhancement. System design and architecture, with evolvement of tool sets, has become an independent skill regardless of programming language. The author here presents the ROBI3 the ice-cream robot (which participants would experience it just below the conference venue) how she managed to link up the its QR code couponing with Gravity Form, one of the most popular plugin for WordPress with minimum coding.

I will give a brief assessment of the current situation, what HKCOTA tried, lesson learnt and road ahead.

PM2.5 is a citizen science project. We provide instructions and open-source code to help people create and customise their own PiM25 box.

When the PiM25 box is ready, air quality and GPS data can upload to the Taiwan's PM2.5 Open Data Portal (Location Aware Sensing System, or LASS) 24/7. Everyone can see the open data from the map (http://airmap.g0v.asper.tw/)

In this session, I will share the project information

TUS is an open source protocol for file uploads. As it is built on HTTP, it supports on any platform. Feature provided by TUS, like resumable upload, solve the problem of unreliable file uploads.

This sharing will introduce how TUS works and have a demo with Node.js.

Present the major new user-visible features and changes in the open-source audio/video VLC media player, as well as other dependent open-source multimedia projects.

這次研計會是讓邀請公眾參與互動、討論、在香港發動全球以中文創建世界語言目錄開源數據庫和語言標準化的開源建議。
我們會討論以下問題：

引言：
什麼是語言？中文（語言）是什麼意思？粵語是一種語言或方言作為書面語/口語嗎？
目前語言由語言學家，研究人員和某些情況下的決策者定義。 Ethnologue.org的世界語言數據庫由SIL.org管理。然而，Ethnologue僅提供有限的公共使用，每天五頁免費訪問語言數據，該網站是英文。
