One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

<?php

use FooBar\Test\Mock;

// In the sample below, $mock expects the method "sayHelloTo" to be called one time 
// with the parameter $name equals "Alexandre" and return "Hello Alexandre"

$mock = (new Mock)([
    'sayHelloTo' => function($name="Alexandre") {
        return "Hello Alexandre";

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
