The EZIO Project proposes a reasonably efficient P2P soultion to deploy bare-metal operating system based on open source software technologies, such as libtorrent-rasterbar and CloneZilla. In this talk, we will discuss the difficult situation of bare-metal deployment in HPC or Cloud, and the performance, reliability and flexibility improvements on existing technologies, such as CloneZilla Multicast Mode.

EZIO has integrated in CloneZilla to provide 1-to-many bare-metal system provisioning on-the-fly, and tested successfully in HPC.

I will introduce to Rust, including the principles, the traits, and the current state of the Rust community. After that, I am going to talk about how to build a minimal DBMS from scratch - the StellarSQL project. In this talk, the following is covered. What is a DBMS? What is the architecture of the DBMS? What is the progress in developing the project? What are the existed resources in the community that I use for the developing? The speech would manifest that developing a small DBMS is fascinating and Rust is cool and powerful.

AI, or more precisely neural network-based machine learning, is getting popular on edge devices. In this talk I'll review TensorFlow Lite + Android NN, the most popular open source NN frameworks on Android, and share my experience of using some recently new features of TFLite, such as TFLite GPU delegate.

We’ve done real-time identification mobile apps on iOS and Android,
without ever taking a picture. We continue to collaborate with
specialists to improve the system.

It is expected that release date of Hyperledger Fabric 2.0 will be in June. This speech will review summary of features in fabric 1.4 LTS and look forward coming design in fabric 2.0. Along with the new version preview, we will discuss the underneath philosophy and concern about why road map diverge from its original proposal in 1.x

長久以來，中文正體的電腦發展都是主要以台灣為基礎。而Windows中的標楷體是香港市民經常使用的電腦字體。但原來標楷體與香港的慣常寫法有很多差異，造成很多應用和學習上的困惑！香港人可以如何自救？有甚麼方法幫到香港人？

R is my favourite language for doing exploratory data analysis. In this talk, I will discuss the use of tidyverse to explore the data. Although, I have mostly used Python to build machine learning models, the ease of use of packages like dplyr and ggplot2 in R allows me to explore the data at high speed and therefore R remains my favourite for exploratory data analysis.

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.

Hong Kong Creative Open Technology Association (HKCOTA) aims to promote Open Standards, Free and Open Source Software, Open Hardware, Free Culture Works, Open Content and Creative Commons. We are encouraging the adoption of Open Technologies by riding on the recent government policies to introduce Popular Science and STEM into current education system.

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