OSDev.org

I just got the books "Modern Operating Systems" and "Operating System design and implementation". Now I realize that any OS developer is probablly not going to get any place with their OS if they don't write a design doc. Either they will have a piece of crap OS,or they won't have an OS at all. An OS is just to complicated to not plan everything out and design it before hand. That's what I'll probablly doing for at least the next month or so.

really, it's that way with any project that's not small....(but even small programs, you should usually wait a day before writing code in order to gather your thoughts...)

It really stands out in OSDEV.

Yup, I've stressed the importance of a design doc a few times.
