java php ruby django email
I am using django. I just want to know is it possible to check if an email is a correct one, so that it will be definitely delivered (99.99%)? If the user entered an email like [email protected], it is technically a valid email but does not exist really. Can I detect such emails?

I performed a short benchmark on a long array in java with quite strange results. It seems that sequential reads with random writes are faster – half the time – than random reads with sequential writes. Has anyone a clue why??Here are two methods that write an array of some longs (run with -Xmx2G or so) by random when reading sequentially and read sequentially when writing by random:import java.util.Random;public class Scratch { static Random random = new Random(); static long[] arr = new long[1
