I'm turning nuts

blog

I feel like I’ve been doing a hackaton these past few days trying to finish my sudoku solver. I had to hand it in 2 hours ago but still haven’t finished… I really hope this won’t affect my grade too much.

I’ve been learning a lot of Emacs, C, using gcov, gprof, LaTeX… I’m so confused right now and my code has became so dense that it’s hard for me to debug it.

Yesterday, suddenly, I found something really stupid in my sudoku grid generation that I couldn’t fix. A day after, I found the solution, randomly, fixing it created a huge load of other issues. I have been re-inspecting my whole code all day long and I’m stressed by this deadline that I already passed.

Gosh that is a hard course.

And… because of this, I missed a day writing on my new application. I was on a 9-day strike :(
