It can come up while installing anything really. I'm not sure exactly which versions of pip are affected, I know I had 1.5.6 and it was affected.

These examples are grabbed from my system level Python, but of course you should use a virtualenv.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

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.

var port = 8080;

var server = http.createServer(function(request, response) {

  response.end();
