i read kip irvine x86 assembly book , have 2 questions. 1) meaning of definition: array2 word 5 dup(3 dup(?)) 2) difference between myarray byte 10,20,30,40,50, 60,70,80,90,100 and myarray byte 10,20,30,40,50 byte 60,70,80,90,100 in array definition? array2 word 5 dup(3 dup(?)) this creates array of 5*3 words, 30 bytes in total. none of these bytes defined value because ? placeholder means assembler assigns space not initialize contents. myarray byte 10,20,30,40,50, 60,70,80,90,100 ... myarray byte 10,20,30,40,50 byte 60,70,80,90,100 both these initializer lists declare same array. in first case list not interrupted transition line added comma. becomes important when using lengthof , sizeof operators. in first case lengthof , sizeof yield 10, in second case they'll give 5.

i'm trying compare 2 dates - check difference between them in minutes. code is: $first_date = new datetime($token->created_at); $first_date->format('y-m-d h:i:s'); $second_date = new datetime(); $second_date->format('y-m-d h:i:s'); $difference = $first_date->diff($second_date); $time_diff = $difference->format("%i"); var_dump($first_date); //i object object(datetime)#552 (3) { ["date"]=> string(26) "2016-04-21 10:00:00.000000" ["timezone_type"]=> int(3) ["timezone"]=> string(3) "utc" } how date datetime object, should compare 2 dates , check difference betwen them. thanks. $difference_in_hours = (($second_date->gettimestamp() - $first_date->gettimestamp())/3600); if difference between 2 dates greater 60 minutes: if($difference_in_hours>1) { //if so, insert desired code here }

imagine that, a div-component had button tag , child-component named input-component ( input tag ), input-component contains action validation. mixin import inside child component. when trigger action mixin, calls child-component ( input-comp ) action getting input value. never try call action on child component. not possible! if try doing wrong! you should update data outside , give down data. data down actions up.

when app in foreground, gcmlistenerservice called , can performance here. if app in background? when app in background, can still receive notification notification part without data part. how can customize on receive event receive gcm message when app in background or closed?? the onmessagereceived() method not called if app in background. there other method works when app in background? https://github.com/google/gcm/issues/63 i have same problem him. , in link there solution. when app in background, need server side make action. data part automatically saved in intent , send activity contains action in content filter.

i have strange issue have following form/php form handler: <form id="search" method="get" action="page.php?pg=xxxxxx"> on submit, in url domain.com/page.pgp?action=xxxx....(more parameters here). how can pass pg=xxxx action url correctly? tried throwing & sign (page.php?pg=xxxxxx&) didn't seem work either. you passing pg value of "xxxxxx" incorrectly. these values should passed in input tags inside form, instance: <form id="search" method="get" action="page.php> <input type="hidden" name="pg" value="xxxxxx"> <input name="submit" value="submit"> </form> the previous code creates form button called "submit", , when press it, takes page action.php query string wanted in url: http://www.foo.com/action.php?pg=xxxxxx hope helps! :)
