It is written in C and Assembly for the kernel and C++ for userspace applications. The project is open-source and available on GitHub.

Main themes

• hobby operating system
• vintage hardware
• font system
• performance optimization
• porting to other architectures
• development documentation

What commenters say

• The author's accomplishment is impressive and deserves recognition.
• The OS's font system is suboptimal and needs improvement.
• Supporting variable-width fonts is relatively easy, but combining characters can be complicated.
• The project's performance is acceptable, but optimization is needed for better results.
• Porting the OS to other architectures, like ARM, would require significant changes.
• The OS's development process could be better documented, potentially through videos or blog posts.
