Every year I pick one personal project for the winter and give it a deadline: the first day of spring. This year it is tmail, a keyboard-driven mail client for the terminal. Should it also talk XMPP and IRC?

Building a DOOM-Like Engine in 2026: Discipline Through Constraints

Wed, 14 Jan 2026 19:53:00 +0000

I’m building (Dark) Lilly Engine, a 3D DOOM-inspired engine in C# with OpenGL. Not to clone DOOM. Not to romanticize the past. But because rebuilding foundational ideas until they’re yours is the only way to truly understand them.

Sometimes the only way to understand a system is to rebuild it. Not copy it. Not romanticize it. Just rebuild the ideas until they’re yours.

It has now been 45 days since I started my “100 Days of Linux” journey on November 24th. The goal was simple but radical: replace macOS and Windows entirely and verify whether Linux could cover everything—development, gaming, productivity, graphics, and daily use—without compromise.

The conclusion so far is clear: Linux has become my main system, and it works flawlessly.
Below is my technical review as of January 7th, 2026.
