in thread Force 2 'ctrl-c's to kill program

Must get my head around what it is doing now.

$SIG{ INT } = sub { ## State makes $last a closure; that is a variable that remember' +s its value ## between invocations of the subroutine state $last = 0; ## if the time now is greater than 2 seconds later than the last +time we saw a ^C if( ( time - $last ) > 2 ) { ## Overwrite the last time with the current time $last = time; ## And just return; ignoring this ^C return; } ## However, if it is less than 2 seconds; die. die 'Interupted by ^C^C'; };

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
