What does “nit” mean in hacker-speak? [closed]

Which “if” construct is faster – statement or ternary operator?
There’s only one type of “if” statement there. The other is a conditional expression. As to which will perform better: they could compile to the same bytecode, and I would expect them to behave identically – or so close that you definitely wouldn’t want to choose one over the other in terms of performance.

PHP shorthand for isset()? [duplicate]
Update for PHP 7 (thanks shock_gone_wild) PHP 7 introduces the null coalescing operator which simplifies the below statements to: $var = $var ?? “default”; Before PHP 7 No, there is no special operator or special syntax for this.

Difference in C# between different getter styles

$(document).ready shorthand

Multiline string literal in C#
You can use the @ symbol in front of a string to form a verbatim string literal: string query = @”SELECT foo, bar FROM table WHERE id = 42″; You also do not have to escape special characters when you use this method, except for double quotes as shown in Jon Skeet’s answer.
