Biggest life saving difference between eclipse and IntelliJ . I don't need to do cltr + s in IntelliJ but in eclipse I need to keep saving changes .
I have lost lot of changes when working with eclipse .

Working with multiple different languages at a time is a crazy fun.
I work with ActionScript , php and JS at a time . So different syntax are ultimate fun . It requires lot of attention
To declare a variable
AS3 : var sample:String = "hello";
Php: $sample = "hello";
JS : var sample = "hello";

And the list goes on .

Insane code. I was printing user name and password in adb log for my android app. So we were reading all the users credentials.
We removed that log before users start knowing it. :p
