// A friend of mine asked me how to limit a function to happen at maximun rate of 1 time every N seconds..
// code:
(

  ~needed_interval = 20;

  ~funk = {

	// if last time isn't defined, create it with 1000 seconds ago time
	if( ~last_time.isNil ) {
		~last_time = Date.getDate.bootSeconds;
		~last_time = ~last_time - 1000;
	};

	// if needed interval has passed, execute the funkie
	if( ( Date.getDate.bootSeconds - ~last_time ) > ~needed_interval ) {

		// safe last execution time, so next calls will have to wait the needed interval
		~last_time = Date.getDate.bootSeconds;

		( "SOMETHING HAPPENS HERE AT MAXIMUN RATE OF 1 TIME EACH" + ~needed_interval + " SECONDS " );

	} {
		( "YOU STILL HAVE TO WAIT" );
	}
  };
)

~funk.value()
