Converting from longitude\latitude to Cartesian coordinates
... often about trade offs, so it all depends on the accuracy you require for what you are doing. For example, the result calculated from "Manhattan Distance Formula" versus the result from the "Distance Formula" can be better for certain situations as it is computationally less expensive. Think "wh...

As for the original question, "What is the “right” way to iterate through an array in Ruby?", well, I think the core way (i.e. without powerful syntactic sugar or object oriented power) is to do:
for index in 0 ... array.size
puts "array[#{index}] =...

SQL JOIN - WHERE clause vs. ON clause
...eliable performance generalizations based on observed behaviors like this. What was true one day tends to be wrong the next, because this is an implementation detail rather than documented behavior. Database teams are always looking for places to improve optimizer performance. I'll be surprised if t...
