Talk #2: Open Source: What, Why and How

Description
Open-source software is everywhere around us; from Linux to Mozilla Firefox and 7-Zip, in many cases, the preferred application for a task is open-source, and much of the Internet today runs on open-source software. We discuss briefly what exactly open-source means, why it is important for the field of computing as a whole and its close ties to hacker culture, and how you can get started both in contributing to open-source and also open-sourcing your own software. In theprocess, we will cover the differences between the major categories of open-source software licenses, as well as some of the philosophy behind open-source software and also free software.

In this talk I'll be walking through what WebAssembly is, its use cases, what it's good at, and its limitations. I'll also speak of my experience at attempting to port one of our older products to WebAssembly.

Straits Times Graphics team published National Day Parade songs project to celebrate the 54th National Day Birthday at the end of June. Since 1984, 26 NDP (National Day Parade) songs were designed to help build Singapore’s national identity by covering various themes and music styles. In this project, three visual graphic types were used; bag-of-words table, radar chart, and scatter chart.

First, we found how NDP song lyrics have changed over the years using basic NLP techniques. Second, we looked inside audio feature information of each song by using Spotify API and visualized to the radar chart in order to compare old and remix versions. Lastly, inspired by Russell's circumplex model of emotion, we designed interactive and dynamic user music emotion chart.

In this talk, we will explore how the music emotion chart
was built with Vue.js mainly. Also, we will get a glimpse of how to extract sounds and lyrics information to enhance the visual story.
