The competition doesn't want you to know about it, but I'm going to tell you anyway.  Studies show that ten species of flowering plants in the Rubiaceae Family, bear seeds that when dried, roasted, and ground up, can have near-boiling water passed through them such that a stimulating beverage is produced.  When taken orally, on a daily basis, and on occasion -- multiple times during the day,  short boosts of alertness and productivity are often observed.  Novice programmers may balk at the bitter taste.  Some may forego the beverage at that point, and usually will suffer the consequences in terms of productivity when compared with their colleagues who continue with the regimen.  Those fortunate enough to have a mentor in this arena will be informed that the bitterness can be offset with the introduction of "creamer", for a smoother, more drinkable texture, as well as the addition of sweetener, whether "Sugar in the Raw" or more processed types.  Veteran drinkers may forego the trip to their local "Coffee" store, in favor of the "do it yourself" model which requires the purchase of a "Grinder" and a "Coffee Pot".  This can usually save time and expense in the long run but a tutorial is beyond the scope of this overview.    In summary, for a sharper IDE and a faster, more responsive cranium,  simply "brew" up a batch of this beverage, and you'll be reapings the rewards in no time.
