VocabularyTest: Building My Own English Vocabulary Practice Tool

Tue, 05 May 2026 00:00:00 +0000

Why Build This?

Vocabulary memorization is probably the most tedious part of learning English. There are plenty of apps out there, but they all seem to have the same problems — too many ads, overcomplicated interfaces, or no way to practice the specific words you care about.

So I built my own.

VocabularyTest is my latest side project: a lightweight English vocabulary quiz web app with one goal — open it, practice, and move on.

📚 Research methodology: All content in this article was compiled using Google NotebookLM, with the infographic also auto-generated by NotebookLM. Sources include NVIDIA official technical documentation and reporting from multiple tech media outlets.

Generative AI is undergoing a paradigm shift—evolving from traditional command-and-response systems into Agentic AI capable of autonomous reasoning, planning, and action. However, bringing AI agents from prototype to large-scale production introduces significant hurdles: model drift, security compliance, and compute costs.

Adding an Interactive Travel Map to Hugo Blog (Leaflet + JSON)

Tue, 10 Mar 2026 00:00:00 +0000

Adding an Interactive Travel Map to Hugo Blog (Leaflet + JSON)

Recently, I wanted to add an interactive map to the top of my blog’s Travel page to mark the places I’ve visited. After some consideration, I decided to use the open-source and lightweight Leaflet.js, paired with a custom JSON file to manage the locations and marker colors.

🗺️ Implementation Goals

Pin a map to the top of /life/travel to display the countries and places I’ve visited.
Centrally manage location data (including English and Chinese names, latitude, longitude, and custom colors) via a JSON file.
Use Leaflet.js to render the map, and automatically calculate the zoom boundaries (fitBounds) based on the JSON data to perfectly fit all markers.
Encapsulate the map into a Hugo Shortcode to easily reuse it across different language pages.

💾 Creating the Data File (Data Layer)

First, create a travel.json file under the data/ directory of your Hugo project. If you have new trips in the future, you just need to update this file without touching any code:

Solving Load Failed Error for Godot HTML5 Exports

Tue, 03 Mar 2026 00:00:00 +0000

Solving Load Failed Error for Godot HTML5 Exports

When making a game with Godot (using version Godot 4.6), I wanted to test exporting it to the web. However, simply opening the exported .html file results in a load failed error. This article documents how to solve this issue by setting up a simple Python server.

After drawing a simple map, test exporting HTML5 package

Directly open html file

🛠️ The Solution

This problem is primarily caused by modern browser security restrictions (especially mechanisms like cross-origin isolation targeting SharedArrayBuffer etc.) causing the file opening to fail to load Godot’s game engine environment.

Building a Micro-World: Playground Pixel Art and Pathfinding Implementation

Building a Micro-World: Playground Pixel Art and Pathfinding Implementation

Recently, while coding, I came across an interesting project on GitHub called Pixel Agents. It simulates AI agents during coding as tiny pixel-style characters working in an office, which looks incredibly cute 😆. Because I really love pixel art, I wondered if I could bring a similar vibe to my own website. That’s how this Playground came to be.

This post will share the implementation details behind this little world, covering how to render crisp pixel art using HTML5 Canvas, designing the states for the characters, and how they navigate the room (BFS pathfinding algorithm).

Hugo Image Management: GitHub vs Cloudflare R2

Hugo Image Management: GitHub vs Cloudflare R2

After setting up my Hugo blog and registering my own domain, I happily started updating the website via git push. But looking at the repository contents, I felt that pushing images together seemed a bit off XD. As I continue updating and maintaining the blog, images will inevitably increase, taking up too much space. Plus, if I switch development environments, I’d have to re-download a bunch of images locally when pulling.

Build an Automated Personal Blog with Hugo + Cloudflare Pages

Build an Automated Personal Blog with Hugo + Cloudflare Pages

Want to create a lightning-fast website that automatically updates every time you git push? This article will guide you through building a personal blog using the Hugo static site generator combined with Cloudflare Pages automated deployment service.

🛠 Why This Combination?

Originally, I used GitHub Pages for hosting, but since the repository must be public, I decided to switch to Cloudflare Pages connected to my GitHub repo. The setup was simpler than expected, and after each git push, GitHub Actions automatically runs and updates the website, ensuring everything works properly.

About Me

Welcome to my blog! This is a platform to record my life.

I created this blog because AI development is really fast these days:O, learning new knowledge and technology is too convenient and too fast, but relatively, I often forget what I have learned, so I decided to record it when I have the opportunity.

Welcome to the Playground — a tiny pixel-art home experiment.

In the scene below, you will see a house made of a living room, bedroom, kitchen, and bathroom, with one male and one female character wandering around randomly.

If you do not see any movement, wait a few seconds or refresh the page.
