* chalk is cleaner, cheaper, more expressive, less wasteful (no plastic), and there are generally more colors available
* chalk stays at full "marking capacity" until it runs out. Dry-erase markers make you write at less than full contrast for a long while until you toss them.
* chalk dust is no problem if you have windows you can open a little
* sounds better when you use it. :)
* nicer light-on-dark contrast (IMO)
But whiteboard gets chosen by non-experts b/c it supposedly makes less dust for electronics/projectors. Unfortunate.
After months/years of not getting nearly enough sleep, how long until you get back to your "normal" mental capacity? (That is, if you go back to getting a reasonable amount of sleep.)
I don't know if I am completely back to normal yet. But I sleep in as much as I can. Few years ago they had to put me on IV drips coz I was throwing up all day due to a week long self-inflicted sleep deprivation. Doctors added something to the drip that put me out for several hours. Thats when I understood that I'll be way better off in the long run with a good sleep schedule.
I used to boast about my ability to code through the night. I was a fool.
I recall an article that claimed you build up sleep debt and have to pay it back with equal time oversleeping.
Obviously there is an upper limit on how much sleep debt any one can accumulate.
In my personal experience, getting enough sleep and not "slipping" requires real discipline.
A good sleep schedule ain't easy to stick to, but it's worth it in the long.
