[ale] sloppy coding in breath tester

[Jeff Lightner]

Funny - reminds me of the Star Trek classic faux pas by Spock.  He
raised a setting "1 to the 4th power".  Apparently 1 to the 5th would
have been overkill... :)

Well, we definitely agree about the blowing smoke part here.

So, as you expect, here is some more smoke...

While not directly coding, I have seen some PhD chemists do absolutely 
horrible things to a simple algebraic expression in support of their 
notions. One of those was also a major "supporter" of using statistical 
methods - like performing a regression on three variables which had the 
constraint a + b + c = 100. Einstein wondered why some of us laughed 
behind his back.

Basic ignorance isn't limited to any field of endevor. Which is sort of 
what I was trying to imply earlier on
