// An example of typeclasses brought to you by addition and multiplication.

// In a traditional OO design, methods are baked into a particular type, so in this example:
println("2 times 2 is: %s".format(2 * 2))
// The method "*" is part of the Int type.

// This is perfectly fine if all the possible functionality for a given type is known 
// at the point when that particular type was compiled. But what do we do if a feature 
// that wasn't expected when a library was built or even if the library was built by 
// someone else?

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
