Falsehoods programmers believe about prices

You can store a price in a floating point variable.
All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
All currencies are subdivided in decimal units (like dinar/fils)
All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
For any currency you can have a price of 1. (ZWL)
Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)

The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Value semantics
Value types in practice
Mixing value types and reference types

Reference semantics

Project Title

One Paragraph of project description goes here

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

A Russian translation of this article can be found here, contributed by Timur Demin.
A Turkish translation can be found here, contributed by agyild.
There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

	1. Add Copy File build phase, Destination: Wrapper, Subpath: Contents/Library/LaunchServices, Codesign on Copy:Disable.

	2. Modify Info.plist for Both target:

	2.1 Add "Tools owned after installation" in App's Info.plist, value is: identifier "<helper's bundle identifier>" and anchor apple generic and certificate leaf[subject.CN] = "<Certificate Name>" and certificate 1[field.1.2.840.113635.100.6.2.1] /* exists */

	2.2 Add "Clients allowed to add and remove tool" in Helper's Info.plist, it is a array, so item 0's value is: identifier "<app's bundle identifier>" and anchor apple generic and certificate leaf[subject.CN] = "<Certificate Name>" and certificate 1[field.1.2.840.113635.100.6.2.1] /* exists */

	2.3 Make sure each .plist file is set as Info.plist in Target's Build settings.

	// #!Swift-1.1
	import Foundation


	// MARK: - (1) classes

	// Solution 1:
	// - Use classes instead of struct
	// Issue: Violate the concept of moving model to the value layer
