I'm the author of the post. I posted it here because I think it can be relevant to programmers.
I understand many people like to work at night, but for those who are ok with getting up early, it's really something worth trying. In my (limited) experience it's not hard to study programming topics when you just woke up, instead it takes a good 30 minutes or more if you want to concentrate on a bright monitor (but you can use a dark color theme to solve that).
Regarding productivity, the reason I believe waking up early works is because you get a big amount of high quality, uninterrupted time, where you are fresh and not tired from the day.
I read your post, but not any previous ones where you may have addressed this: is the sun up at 5am where you live? I always find it much easier to wake up early if the sun is already up. If the sun is still down, do you do anything to trick your body into thinking the sun is up? Does it help?
