at our company using web application shared licenses. unfortunately if closes tab application running in wont release license lock. wondering whether possible run/trigger scipt when firefox tab closed, automatically release licenses? think greasemonkey might able this, haven't found solution yet. there both window.onbeforeunload , window.onunload , used differently depending on browser. can assing them either setting window properties functions, or using .addeventlistener : window.onbeforeunload = function(){ // } // or window.addeventlistener("beforeunload", function(e){ // }, false); usually, onbeforeunload used if need stop user leaving page (ex. user working on unsaved data, he/she should save before leaving).

basically converting php codeigniter's encryption method python stuck while converting php's mcrypt_create_iv library python. thanks in advance. mcrypt_create_iv() php interface os-level pseudo-random generators (it's not part of libmcrypt, contrary function name implies). python provides such interfaces via os module , need os.urandom() . for example, if need translate mcrypt_create_iv(16, mcrypt_dev_urandom) python, you'd need write os.urandom(16) . to clarify possible confusion: you may've used mcrypt_dev_random or mcrypt_rand in php, there literally no reason use either of instead of mcrypt_dev_urandom - better measurable criteria: mcrypt_rand in particular not suitable cryptographic purposes, or in other words - insecure . mcrypt_dev_random can , block until new entropy data available. don't want blocking in web application , myth /dev/random somehow better /dev/urandom because of blocking has been debunked . mcryp

if have following code in javascript: var index1 = (math.random() * 6) >> 0; var index2 = math.floor(math.random() * 6); the results index1 or index2 anywhere between 0 , 6 . i must confused understanding of >> operator. thought using arithmetic shift results index1 anywhere between 1 , 6 . i noticing, don't need use math.floor() or math.round() index1 if use >> operator. i know can achieve adding 1 both indexes, hoping there better way of ensuring results 1 6 instead of adding 1 . i'm aware bitwise operators treat operands sequence of 32 bits (zeros , ones), rather decimal, hexadecimal, or octal numbers. example, decimal number 9 has binary representation of 1001. bitwise operators perform operations on such binary representations, return standard javascript numerical values. update: i saw original usage in caat tutorial on line 26 , wondering whether return random number between 1 , 6 , seems ever return random number b
