Hi, I’m Kuibin!

Thanks for stopping by!

This site is a personal project I’m building as I learn WordPress. It’s part of my ongoing journey into programming and tech, and occasionally I’ll share random bits about my home lab setup or whatever programming challenge I happen to be tinkering with.

I’ve always been curious about how things work behind the scenes — especially when it comes to computers and software. Although I didn’t get the chance to study programming formally at university, I’ve been learning bit by bit through online courses, YouTube tutorials, and hands-on experimentation. Over time, I’ve explored everything from Python and web development to setting up self-hosted services using Raspberry Pi, Docker, and Proxmox.

This site is a space for me to document that learning journey — whether it’s something I’ve just picked up or a note-to-self for future reference.

The name Four Brackets comes from the four types of brackets commonly used in programming: (), [], {}, and <>. These symbols may be small, but they’re fundamental to how we write and structure code across different languages and environments — whether it’s calling functions with () in C, Python, or JavaScript; accessing lists or arrays with [] in Python and JavaScript; defining code blocks with {} in C, JavaScript, and many scripting languages; or marking up content with angle brackets <> in HTML and XML. Brackets also play key roles in other contexts: {} are essential in data structuring formats like JSON; [] are used for array indexing in Bash scripts; and <> appear in Unix/Linux shell redirection. Each bracket type helps express, organise, and execute logic — whether you’re writing compiled programmes, scripting in a Linux terminal, or working with structured data or markup.

If any of this resonates with you or you’re just curious about home labs, programming, or tech in general, feel free to get in touch — you’ll find my contact details on the Contact page.

This is where I am for now — Singapore.
