The issue: Sometimes, it’s hard to get out of a comfy bed and face the cruel and merciless world. Proposal: We can solve this problem by making a bed that becomes progressively less comfortable as the desired wakeup time arrives. Certain mattresses already have the ability to dynamically adjust their firmness (for example, the “Sleep…

Background: In programming, there is the notion of “code smell”—a subtle indication that something is terribly wrong in a piece of source code, but without any (obvious) actual mistake. For example, if you saw the following: print(“E”); print(“RR”); print(“OR”); print(“!”); instead of print(“ERROR!”); that would be a good indication that something extremely bizarre was going…
