Speed up your Analytics Projects using Delta Lake on Azure

Delta Lake 是一個開源項目,可以在現有存儲系統(例如 ADLS 和 HDFS)之上構建 Lakehouse 架構,並與 Apache Spark API 完全兼容。 Delta Lake 為您的數據湖帶來 ACID 規範。它提供數據快照,使開發人員能夠查找和恢復到早期版本的數據以進行審計、數據恢復或實驗。實時數據提取、批量數據整合和交互式查詢都能夠開箱即用。Mike Chan 將為我們介紹 Delta Lake 的好處和最近的使用體驗,讓大家能充份發揮不同數據的潛能。

Introducing Quarkus: a supersonic, subatomic Java framework

Quarkus is an open sourced, Kubernetes-native Java framework made for Java virtual machines (JVMs) and GraalVM native compilation. Quarkus is optimized specifically for containers. It greatly minimizes application startup time and memory use, and it provides live coding so that developers can immediately check the effect of code changes in the blink of an eye. With these features, they enable Quarkus to become an effective platform for serverless, cloud and Kubernetes environments. Join this session to have a first look into Quarkus.

Drug Icon CC:藥物圖標 Creative Commons

Drug labels in Hong Kong are mainly presented in words. Elderly or ethnic minorities might find it difficult to fully understand them. The carers need to spend extra time explaining and handwriting remarks to ensure medication adherence. 

We took reference from other places’ prescription labels and designed a set of unified Drug Icons, which can be stuck on the medicine packages to visualise the prescription notes for easier understanding.

Building online technical community in the era of COVID-19 / 疫情時代我經歷的線上技術社群經營

It’s hard to arrange community events after COVID-19 pandemic. But there is still a strong need to gather, to share, and to learn from other developers. In this talk, I will share our experiences of how to build the Koltin community online in Taiwan from 2019 to present. The topics will be about how we arrange study jams, how we run workshops, how we build a team to attend competitions, how we connect companies to become a league, and the most important, how we grow the community and the lesson learned.

I write my own web desktop OS for 3 years and this is what it looks like now 用了三年時間寫網頁桌面作業系統的故事

This will be a short talk mentioning the updates of the Open ArozOS project I shared in last year's conference. The share will include the story of transitioning a project from PHP based to Golang based, a newly open sourced ESP8266 powered IoT control system for prototyping and some new development concepts that involving PWA technology using ArozOS as the backend. If there are excess time, I might also discuss the design advantage when developing complex system using Web Desktop UI instead of the traditional Dashboard UI.
