// Script I hacked together to cheat on TypeRacer.com. You use it by waiting for the typing game
// to start. Once it starts, open up Firebug, paste in this code, and run it. Now, just press
// space to auto-type each word. I made the user push space, as opposed to advancing the words 
// automatically because I believe the site looks for a keypress event before evaluating the contents
// of the input box. I could not figure out how to fake a user keypress event. Perhaps this is
// disallowed for browser security reasons?
//
// Next todo: Site detects the unbelievable WPM and asks you to do a captcha test.

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

Answering the Front-end developer JavaScript interview questions to the best of my ability.

• Explain event delegation

Sometimes you need to delegate events to things.

• Explain how this works in JavaScript

This references the object or "thing" defined elsewhere. It's like "hey, thing I defined elsewhere, I'm talkin' to you."

• Explain how prototypal inheritance works.

According to http://www.zsh.org/mla/users/2015/msg00727.html the order gets overwritten by path_helper.

If you move your $PATH settings from ~/.zshenv to ~/.zprofile path_helper won't override your PATH settings.
