Only 1.5 chapters remaining until my book is finally done. I’m at >450 pages so far & it’s likely going to be ~600. Y’all. Hundreds of hours and several breakdowns went into this. I can’t wait for it to be finished and hope you appreciate the sweat and tears that went into it.

I’m currently studying the 800p Windows Internals Part 1 book and it feels like I’m cheating on Linux.
