lat2 = asin(sin(lat1)*cos(d/R) + cos(lat1)*sin(d/R)*cos(θ))
lon2 = lon1 + atan2(sin(θ)*sin(d/R)*cos(lat1), cos(d/R)−sin(lat1)*sin(lat2))

Don Stewart - Google+ - Great phrase from Conor McBride -- I like to think of types…
Great phrase from Conor McBride -- I like to think of types as warping our gravity, so that the direction we need to travel [to write correct programs] becomes "downhill".
I rely on the use of rich types to infer much of the software I write -- to just "derive" fragments of the software from its type specification, and get on with the interesting work. No room for hacks or misadventure to creep in, since there's only a few possible programs with the correct type.
And after years of richly typed programming, it is easy to forget how unusual - and luxurious - this engineering methodology is.
