How to set up stress-free SSL on an OS X development machine

One of the best ways to reduce complexity (read: stress) in web development is to minimize the differences between your development and production environments. After being frustrated by attempts to unify the approach to SSL on my local machine and in production, I searched for a workflow that would make the protocol invisible to me between all environments.

Most workflows make the following compromises:

Use HTTPS in production but HTTP locally. This is annoying because it makes the environments inconsistent, and the protocol choices leak up into the stack. For example, your web application needs to understand the underlying protocol when using the secure flag for cookies. If you don't get this right, your HTTP development server won't be able to read the cookies it writes, or worse, your HTTPS production server could pass sensitive cookies over an insecure connection.
Use production SSL certificates locally. This is annoying

Protocol-Oriented Programming in Swift

Speaker: David Abrahams. (Tech lead for Swift standard library)

"Crusty" is an old-school programmer who doesn't trust IDE's, debuggers, programming fads. He's cynical, grumpy.
OOP has been around since the 1970's. It's not actually new.
Classes are Awesome
- Encapsulation
- Access control

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

##Basic Steps

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?

	Usage: $0 [OPTION]... COMMAND
	Execute the given command in a way that works safely with cron. This should
	typically be used inside of a cron job definition like so:
	* * * * * $(which "$0") [OPTION]... COMMAND

	Arguments:

	// In languages like Python and Haskell, we can write list comprehension syntax like
	// super simply to generate complex lists. Below, for example, we find all numbers that are
	// the product of two sides of a triangle.
	// [a * b \| a <- [1..10], b <- [1..10], c <- [1..10], a * a + b * b == c * c]

	// Why is this called nondeterministic computation? Because we essentially try ALL possible combinations
	// of these values (a,b) and--you can imagine--run them all simultanously and get the result that matches the predicate.
	// Now, obviously, this doesn't all happen at the same time, but that's the idea behind the nondeterminism.

	// Let's examine how we can get a similiar result in Swift! We'll start super simple and work
