Crazy thought. What if Apple included an A5 and a Core i3 or i5? Further crazy, much like OS X using an available, discrete CPU if needed, it used the A5 as much as possible, but switched to the Core if necessary.
Such a thing may not even be pratical, but seems more likely to me than Apple dropping Sandy Bridge processors for ARM.
One-off lateness can be the result of public transportation. Consistent lateness isn't.
Now, when is punctuality important? I don't care about 9 vs. 9:30 when getting into the office. I do care care about perpetually running 5 minutes late to a 15 minute team status meeting. There's an unspoken agreement at play; Meetings are short when people show up on time, ready to listen or speak.
A good interview process should be resistant to gaming. For instance, multiple interviews. Multiple people doing the interviewing. Asking the candidate to demonstrate a capacity to do the work.
But, let's say the candidate does successfully game the interview and gets hired. Your company should absolutely use the first N-days of a new hire to check fit. Many I've seen explicitly say the first three or six months is a probationary period. The problem is when companies aren't honest with themselves about making a bad hire (capability or fit) and letting the new hire go.
Particularly for internal job candidates, I highly recommend being direct and saying, "Here's where you're short. Here's what you can work on over the next year or so to get into a better position. It's not a guarantee, but you'll be better prepared." Give them homework.
If a candidate is really and truly interested, they'll follow through on the advice and follow-up on it. That gives you a better candidate to look at for your next req.
MacRuby and RubyCocoa are two separate projects. MacRuby is not a Cocoa bridge like RubyCocoa is. It's a complete reimplementation of Ruby's primitives in Objective C to allow you to compile a Ruby app to a double-clickable app bundle.
