I've taken that hardline approach for years and flat out refuse to help by saying, in essence, "I don't use it, I don't know it."
If I had to guess, I'd say heritable immunity.
const int one = 65536;
As an aside (that means off-topic, guys) this looks like part of a fixed-point arithmetic implementation. It may not be as silly as you think.
Those genes are not expressed, and we don't have copies of those viruses floating around our bloodstream.
Probably, and for the most part. But we used to think the genome was mostly "junk DNA" before we understood that much of it was homeotic in function. It seems to me that virus copies would not be conserved over time unless they were serving some function.
In space, no one can hear you fart.
