This is hilarious! I wish I could really write code that fast.
Most of my actual coding is head-scratching and browsing documentation.

#32It'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 ?

#33Earlier 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.
