Should I put an article on lighting calculation on Habrahabr or on Geektimes?

Question

Habr

I am preparing an article on the methods of manual express assessment of illumination in a room, as an alternative to using special software - Dialux. The method will be presented in a simplified version, in the classical more accurate version, and the calculation will be checked in dialux.
For example, one room will be calculated by all methods. The final figures will be indicated and compared, and the calculation time by all three methods will be indicated, and a conclusion will be drawn. Of course, there will be beautiful illustrative pictures.
There will also be an advertising component - an expression of gratitude for the courses in which I learned this, and a link to the course website.
Question: where should I publish this article - on Habrahabr or on Geektimes?
