Reading the fine print, episode 3: What's in the bottle?

Caught out by the FDA. I happened to be in the bug spray section of the store when I spotted a bottle of mosquito repellant that proudly proclaimed “100% DEET”. But the FDA-mandated labelling tells a different story:

Active ingredients
N, N diethyl-m-toluamide      
95%
Other isomers  
5%

Similarly, foods labeled “zero fat” are actually allowed to contain up to a half gram of fat. (Well, up to but not including.) This is a definition of “zero” with which I had previously been unfamiliar.

Raymond has been involved in the evolution of Windows for more than 30 years. In 2003, he began a Web site known as The Old New Thing which has grown in popularity far beyond his wildest imagination, a development which still gives him the heebie-jeebies. The Web site spawned a book, coincidentally also titled The Old New Thing (Addison Wesley 2007). He occasionally appears on the Windows Dev Docs Twitter account to tell stories which convey no useful information.
