Install web development tools to Mavericks (OS X 10.9)

Strongly opinionated set of guides to quickly setup OS X Mavericks for web development. By default OS X hides stuff that normal people don't need to see. These settings are better defaults for developers.

I don't want: any sounds, annoying confirmation dialogs, hidden extensions, superflous animations, unnecessary things running like Dashboard, Notification center or Dock(Alfred/spotlight works better for me).

These are my opinions. Read this document through and pick up the good parts to your preferences.

Abstraction Suggestions

Summary: use good/established messaging patterns like Enterprise Integration Patterns. Don't make up your own. Don't expose transport implementation details to your application.

Broker

As much as possible, I prefer to hide Rabbit's implementation details from my application. In .Net we have a Broker abstraction that can communicate through a lot of different transports (rabbit just happens to be our preferred one). The broker allows us to expose a very simple API which is basically:

• publish
• request
• start/stop subscription

I agree the point you’re making here, 100%. However, a slight correction about Node’s APIs.

First of all, process.nextTick is actually first in, first out. Proof:

$ node -e 'process.nextTick(console.log.bind(console, 1)); process.nextTick(console.log.bind(console, 2))'

Secure sessions are easy, but not very well documented.  
Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

The desired configuration for using NginX as an SSL proxy is to offload SSL processing 
and to put a hardened web server in front of your Node.js application, like:

[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]

Edit for express 4.X and >:  Express no longer uses Connect as its middleware framework, it implements its own now.

Ideas for improvements to git log --graph

I will maybe someday get around to dusting off my C and making these changes myself unless someone else does it first.

Make the graph for --topo-order less wiggly

Imagine a long-running development branch periodically merges from master. The git log --graph --all --topo-order is not as simple as it could be, as of git version 1.7.10.4.

It doesn't seem like a big deal in this example, but when you're trying to follow the history trails in ASCII and you've got several different branches displayed at once, it gets difficult quickly.
