| Your goals are to reduce the number of things that you have to keep in your head at any given moment, and to rely as little as possible on your own ability to consistently do things right. | |
| If you make a thing immutable ('let' in swift), you never have to think about what happens if it changes, or what other parts of the code you'll effect if you change it. | |
| If you split complex functions into several smaller functions that only interact by passing arguments or getting return values, then you limit the amount of code you need to consider when hunting for a bug, and you can test each small piece separately. | |
| If you understand what things must be true in your code (aka invariants, for example "a person's age must be greater than 0"), and either provide no function that can cause them to be untrue, or check and crash immediately when they're untrue, then you don't have to debug issues caused by incorrect assumptions. | |
| If you remove possibilities (for example, Swift removes the possibility of things being nil unless |

Since modern.ie released vagrant boxes, it' no longer necessary to manually import the ova file to virtualbox, as mentioned here.
However, the guys at modern.ie didn't configured the box to work with WinRM. This how-to addresses that, presenting steps to proper repackage these boxes, adding WinRM support. Additionally configures chocolatey package manager and puppet provisioner.

Season's Greetings, NSHipsters!
As the year winds down, and we take a moment to reflect on our experiences over the past months, one thing is clear: 2014 has been an incredible year professionally for Apple developers. So much has happened in such a short timespan, and yet it's hard to remember our relationship to Objective-C before Swift, or what APIs could have captivated our imagination as much as iOS 8 or WatchKit.
It's an NSHipster tradition to ask you, dear readers, to send in your favorite tips and tricks from the past year for publication over the New Year's holiday. This year, with the deluge of new developments—both from Cupertino and the community at large—there should be no shortage of interesting tidbits to share.
Submit your favorite piece of Swift or Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!
If you're wondering about what to post, look to

| /* This is a FluidApp userscript for Google Inbox for Mac. | |
| Includes options for total badge count and unread badge count. | |
| 1) You need the paid version of FluidApp (http://fluidapp.com/) | |
| 2) Point Fluid to https://inbox.google.com (I recommend the icon from here: https://medium.com/@chrismessina/create-an-icon-for-google-inbox-in-your-dock-ed269312e3bc) | |
| 3) Set the user-agent to Chrome | |
| 4) Go to window -> userscript and add click the plus sign under the first table (on the left). Name the item 'Inbox'. | |
| 5) In the second table (on the right) click the plus and type in "*inbox.google.com*". | |
| 6) Paste the contents of this document into the script area below that. | |
| 7) Configure badge count (for total or unread only) in the code below. |
