It's not hilarous on an iPad 1. Nothing happens beside the prompt blink. How could I look insanely busy with that in a coffee shop ? ;)

Can't look busy on my phone either.

I guess we are supposed to bring our desktop computer in the coffee shop ;) it's for laptop users, but this is so oldish. Who is still doing that ?

Earlier quoted context omitted.

I've seen it used a lot in Objective-C for default values: NSNumber *value = dict[@"key"] ?: @1;

?: is the "Elvis" operator.

The standard name is the "Null-coalescing" operator, see http://en.wikipedia.org/wiki/Null_coalescing_operator .

It's only called "Elvis" in Groovy. The name was announced one day by its Project Manager as part of a marketing campaign to make the name "G-String" mean a string on Elvis's guitar instead of a revealing item of clothing.
