About

Hello! Thank you for visiting.

I’m Ruoyu, a Computer Science student currently pursuing a Master’s degree in Infocomm Security at the National University of Singapore. My interests lie in cyber security, open-source software, and programming in general.

I enjoy writing efficient and effective software, as well as appreciating those written by others, and working with them under various circumstances. I am a frequent contributor to open-source projects – maybe you have used some of them. I devote most of my open-source contributions to maintaining the Homebrew package manager, which I am also proudly a maintainer of. If you have brew installed, you can find my name in the output of man brew | grep Ruoyu.

This site was created on 25 April 2020. It has undergone two major revisions. The first revision, completely redesigned and rebuilt from the initial version, was published on 24 July 2020. The second and current one, as a complete rewrite of the previous version, focusing on design simplification and extensibility, was made available on 4 May 2022. It is also available as a blog theme. The domain, www.ruoyu.xyz, was put into use on 16 July 2020.

As you can probably tell, I spend way too much time on the blog theme/engine than producing blog posts, so there are not many posts here as you might expect and I would like to have. To keep up with my latest work, it may be a good idea to check out my GitHub profile.
