Cedar is an open-source language and software development kit (SDK) for writing and enforcing authorization policies for your applications.  Using Cedar, you can express fine-grained permissions as easy-to-understand policies enforced in your applications, allowing you to decouple access control from your application logic. In this session, we will introduce the core concepts behind the Cedar policy language and authorization engine, as well as how you can leverage this open source project to add access control into your applications.

Platform engineering, also known as an "Internal Developer Platform" aims to provide developers with a seamless and efficient environment to manage the entire lifecycle of an application. Django, a popular open-source web framework, is known for its rapid development capabilities and clean, pragmatic design. By leveraging its built-in features, one can expedite the process of developing platform engineering solutions. In this session, I will share my experience using Django for platform engineering at an AI company.

Open Cultural Data can speed up knowledge sharing between several cultural institutions and museums to digital images sharing projects. By understanding the impact statement of Sri Lankan Agricultural Village and Eco-Farm in Sheung Shui, developers are invited to publish street map and open cultural data for facilitating social integration of Sri Lankans residents in Hong Kong and value co-creation.

The Common Spatial Data Infrastructure (CSDI) is a key initiative under the Smart City Blueprint for Hong Kong. The CSDI portal launched by the Development Bureau (DEVB) provides a map-based digital infrastructure as a one-stop platform to open and share spatial data. By allowing members of the public to search, view and download various kinds of spatial data from the portal, a wide range of possibilities for application development will be opened, the digital economy boosted and quality of life improved.

In 2022, I launched a Kotlin podcast show, Kotlin Fireside Chat, with my friends in Kotlin User Group. Now, we're taking things to the next level by building a podcast website with a statistical analysis dashboard. We've built a static website using Jamstack and connected it to a serverless API written in Kotlin. In order to aggregate the listener number across platforms, such as YouTube, BiliBili, Ximalaya, Lizhi, Qingting, we've also created a crawler to grab those numbers and display them in a custom dashboard.

The Domain Name System (DNS) has changed dramatically over the last decade. There are now more than 1,200 active generic Top-Level Domains (gTLDs) representing many different scripts and character strings of varying length (e.g., .дети, .london, .engineering). There are also more than 60 Internationalized Domain Names (IDNs) country code top-level domains (ccTLDs) representing global communities online in native scripts (e.g., .ไทย).
