Hi everyone, I'm Chris Wanstrath.

When Jeremy asked me to come talk, I said yes.  Hell yes.  Immediately.  But
then I took a few moments and thought, Wait, why?  Why me?  What am I supposed
to say that's interesting?  Something about Ruby, perhaps.  Maybe the
future of it.  The future of something, at least.  That sounds
keynote-y.

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

Are your feelings hurt?

If you rushed through David Shariff's JS Quiz or are just new to JS they might be. I know mine were. After I dried my eyes, I took the quiz again, this time very slowly trying to get at the meat behind each answer. Below is my attempt to explain each question's answer and offer some interesting permutations so that others can move beyond their hurt feelings and come out the other side better JS developers.

I initially thought I'd turn this into a blog post but think it's probably better as a gist.

Question #1

Don't over think it.

var foo = function foo() {

# ssh(1) obtains configuration data from the following sources in the following order:
#
#       1.   command-line options
#       2.   user's configuration file (~/.ssh/config)
#       3.   system-wide configuration file (/etc/ssh/ssh_config)
#
# For each parameter, the first obtained value will be used.  The configuration files contain sections separated
# by “Host” specifications, and that section is only applied for hosts that match one of the patterns given in the
# specification.  The matched host name is the one given on the command line.

Here are seven JavaScript concepts you must understand before you go into your next JavaScript job interview:

1. Prototypes - JavaScript is a prototype-based language. Even more, it's a delegation-based system, which means that each object has a prototype chain. When you try to access a property on an object, and that property is not found, JavaScript looks at the object's prototype. The prototype is a delegate object, which means that the property lookup is delegated to the prototype object. That object, in turn, may have its own prototype. The search continues up the prototype chain until it reaches the root prototype, which is usually Object.prototype. The best feature of this system is that many object instances can share the same methods on a prototype object, which conserves memory and enables easy code reuse. To assign a prototype to a new object, you can use Object.create(prototypeObject). Prototypal OO is the first course being offered in the "Learn JavaScript" series.

2. Functional Programming

Learning Computer Security

About This Guide

This is an opinionated guide to learning about computer security (independently of a university or training program), starting with the absolute basics (suitable for someone without any exposure to or knowledge of computer security) and moving into progressively more difficult subject matter.

It seems that most people don't realize how much information is actually available on the internet. People love to share (especially geeks) and everything you need to become well versed in computer security is already available to you (and mostly for free). However, sometimes knowing where to start is the hardest part - which is the problem that this guide is intended to address. Therefore, this guide can accuratley be described as a 'guide to guides', with additional recommendations on effective learning and execises, based on my own experiences.

Many of the free resources are the best resources and this guide focuses on them. It is intended to provided a comprehensive

"How do I get started with Node?" is a commonly heard question in #Node.js. This gist is an attempt to compile some of the answers to that question. It's a perpetual work-in-progress.

And if this list didn't quite answer your questions, I'm available for tutoring and code review! A donation is also welcome :)

Setting expectations

Before you get started learning about JavaScript and Node.js, there's one very important article you need to read: Teach Yourself Programming in Ten Years.

Understand that it's going to take time to learn Node.js, just like it would take time to learn any other specialized topic - and that you're not going to learn effectively just by reading things, or following tutorials or courses. _Get out there and build things!
