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

I'm planning on either writing this up in detail or maybe doing a screencast about screencasting, but I'll give a short version here.

On sound quality:

This matters a lot. In decreasing order of importance:

Remove echo. You have to hear this to understand. Set up a mic in front of your mouth and record a sentence. Then, put a thick comforter over you and the mic and say it again at the same distance. Listen to

	require "net/http"
	require "uri"
	require "json"
	require "openssl"
	require "yaml"

	OAUTH_TOKEN = "some token goes here"

	uri = URI.parse("https://api.github.com/users/enocom/repos")

	# Here are a handful of good practice problems, some of which may show up in interviews.

	# 1. Write an anagram function.
	# After that, try writing an anagram function without using #sort and iterating over each word only once
	anagram("orchestra", "carthorse") # returns true
	anagram("orchestra", "apple") # returns false

	# 2. Write a function to test for balanced parentheses.
	# This was a Twitter interview question, by the way.
	balanced("()") # returns true

	package main

	import "fmt"

	type T struct{}

	func (t T) Method() {
	fmt.Println("Hey there")
