Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

// Easter calculation in swift after Anonymous Gregorian algorithm
// Also known as Meeus/Jones/Butcher algorithm

import Foundation

func easter(Y : Int) -> NSDate {
  let a = Y % 19
  let b = Int(floor(Double(Y) / 100))
  let c = Y % 100
  let d = Int(floor(Double(b) / 4))
