About

Hello. I am a developer engaged in learning and system software development activities in the field of computer science.

Major Projects and Activities

My primary ongoing project is Nimf, a multilingual input method that operates in Linux and BSD environments. Nimf began as a personal development project in 2015, was initially released as open-source, and has been distributed as freeware since 2019.

I also designed and implemented the Common Input Method (Cim) architecture to address the issue of input method separation (XIM, Gtk-IM, Qt-IM, etc.). Furthermore, I published an analysis of the technical limitations of the Wayland input protocol. Concurrently, I contribute bug patches to operating system and core library projects such as FreeBSD, libx11, and glib, fostering interaction with the development community.

Current Research and Plans

Recently, I have been focused on the Ada language and am currently writing an Ada programming textbook. I am also preparing to port the existing C language implementation of Nimf to the Ada language to enhance the safety and reliability of the system software.

Areas of interest include reliable software development, artificial intelligence, GUI toolkit design and implementation, and text processing. These topics are closely related to operating system structure and user interfaces.

Interests

Music is an old friend of mine. I am always with music, enjoying various genres including classical, Chinese songs, and Korean pop.

Contributions and Record

Based on humanism, I contribute to and financially support various software projects that I need. This list is a transparent, albeit partial, record of my activities. It was also created to stand as a factual counter to baseless criticism.

Regarding the challenges I’ve faced, please refer to my blog posts: “My Nimf Project: A 5-Year History of a Narcissistic War” and “The Bare Faces of Some People”.
