The family of problems where computing is non-deterministic and there is no single right answer is very large. Many gossiping algorithms belong to that family, as do several finance problems with an underlying stochastic model. Here's a ver

true story. when I was 16 ( way back in the early 90s), my parents enrolled me in niit.com (presently a billion USD company that was at the time a tiny 3-room outfit ). niit taught cobol. I hated everything about cobol. I thought it was a s

if you are comfortable with returning tuples, perhaps the inputs should be a tuple as well... def findRoot(p:(Double,Double,Double)) = { assert(p._1 != 0) val n = sqrt(p._2*p._2-4*p._1*p._3) val d = 2*p._1

There's no real argument cause these are orthogonal concerns. In general, you'll have a bunch of concerns. 1. BCNF 2. ACID 3. Performance 4. Scalability 5. Ease of implementation Before noSQL, you'd prioritize in that exact order. Post noSQ

Didn't get any of that so had to redo in metric. speed of light = 3 x 10^8 m/s 3 GHZ = 3 x 10^9 /s So 3 x 10^8 / 3 x 10^9 = 0.1 metre = 10 centimetre = okay, 3.9 inches But then metric always saves your ass. Back in physics class, they'd as
