I have seen several places, including Wowhead, mentioning that you can use your daily cooldown twice during the same day if you have a profession building related to one of your professions. None of these places elaborated on exactly how to get it.
For example, I have engineering and can make Gearspring Parts once a day. I get 5 for doing that. I also have the engineering building, but I can't make more batches of Gearspring Parts. I'm also supposedly going to be able to get 6 Gearspring Parts from the engineering building each day, but I have yet to figure out how.
Edit: Actually, I read now that you are supposed to get 10 unique resources daily regardless of having the relevant profession building or not, as long as you have the profession. I'm not sure how this works.
