/**
 * Like, basically PERFECT scrollbars

/* 
   It's pure CSS. 
   Since a quick google search will confirm people going crazy about Mac OS Lion scrollbars...
   this has no fade-out effect.
  
   In Mac OS Lion, the lowest common denominator is always showing scrollbars by a setting.

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

A couple ways to submit (publish, upload) a Visual Studio Xamarin.iOS app to the App Store

Option 1: upload an IPA created via the "Build Adhoc IPA" command

1. Pick the "Ad-Hoc" build configuration.

2. Change the provisioning profile in "project options -> iOS Bundle Signing" to an AppStore provisioning profile.

3. Rebuild the project.
