A MIPS-based Radix Converter Project

Chris — Sun, 26 Mar 2023 00:00:00 +0800

What is this

This project implements a MIPS-based radix converter that converts numbers from Decimal to various bases. The converter is developed in MIPS assembly language and executed using QtSpim. Completed as part of the COMP2421 course at the HKPolyUHong Kong Polytechnic University.

Features

Converts numbers from Decimal to binary, quaternary and octal bases.
Supports both positive and negative integers.
Handles invalid inputs gracefully.

My thoughts

Writing a simple program in assembly was quite a challenge. Compared to high-level languages like Java or Python, I realize how tricky even basic logic could get in MIPS. That said, completing this project was both rewarding and enjoyable.

What is this?

This project implements a containerized, event-driven microservices architecture backend RESTful API, designed with reference to UberEat API, Completed as a group project as part of the COMP3122 course at the HKPolyUHong Kong Polytechnic University.

Features

Microservices architecture with event-driven communication
Docker Compose for container orchestration and deployment
RESTful API endpoints
Comprehensive unit testing
UberEat API-inspired design for scalability and maintainability

My Thoughts

This project was a great opportunity to learn about microservices architecture and event-driven design patterns. I enjoyed working with Docker and Flask to create a scalable and maintainable backend API. The experience of collaborating with a team to build a complex system was invaluable, and I learned a lot about software development.

IQ Test Android App

Chris — Thu, 16 Jul 2020 00:00:00 +0800

What is this

This is a Java-based IQ test Android app that I developed as a project for my ITP4501 course. The app is designed to provide users with a series of numerical reasoning questions and evaluate their performance based on their answers. The project was completed as part of the ITP4501 course at the HKIVE.

Features

User-friendly interface for easy navigation.
Multiple-choice questions with instant feedback.
Score calculation based on user responses.
Option to view correct answers for incorrect responses.
Timer to track the time taken for each question.
Results summary at the end of the test.
Database integration using SQLite to store test questions, user scores and test history.
Scoreboard to track progress over time.
Bar chart visualization of scores.

My thoughts

Developing this app was a great learning experience for me. I learned a lot about Android development, Java programming, and database management. I also gained valuable insights into user experience design and how to create an engaging app. Overall, I am proud of the final product and believe it showcases my skills and knowledge in Android development.

Personal Home Page

What is this?

This is my personal home page, you are visiting, created with Hugo and LoveIt theme, and hosted on GitHub Pages. It serves as a place for me to share my thoughts, projects, and interests with the world.

Features

Personal blog posts
Project showcases
Search functionality
Links to my social media and other platforms

My thoughts

My old personal page was made 3 years ago, and I think it is time to update it. But the old version was hard to maintain, so I decided to use Hugo and LoveIt theme to create a new one, which is much easier to manage and customize. I also want to make it more user-friendly and visually appealing. So, I hope you will enjoy my new personal home page!
