TSGL: weird symbols

[Mike Ferrell]

In statistics there are type 1 errors and type 2 errors with type 1 being a 
false positive and type 2 being a false negative.  Type 1 being if you 
accepted something that should have been rejected, and type 2 if you 
rejected something that should have been accepted.  Statistical tests always 
involve a trade-off between how many false positives and false negatives can 
be safely accepted.  This plays a role in a wide range of sciences including 
medical testing for example.  As for computers, I would imagine it is 
relevant in identifying spam, malware, virus, etc.  Having a chemistry 
background and not a computer background I can offer little more.  Plus, 
I've been retired too long and any memory of statistics is faint, for which 
I am eternally grateful. :-)  But I'm sure there are those on "the list" who 
can explain it's relevance to computers and why it might be showing up.

This set of symbols has started appearing, unasked, on my daughter's
laptop, just above her signature on her emails. Anybody have any idea what
it is, where it comes from, and why?
