i have directive calculates height , distance top of window of element passed in id attribute. issue i'm running have several of these directives running (on elements attached same directive), , i'm running race condition of directives lower down in dom running before ones higher whatever reason. is there way can make bottom ones wait ones higher via promise or something? if so, how implement that? there better way of handling this? if want code executed directive in descending order (higer in dom comes first), should either put code in directive's controller , or prelink methods. the default link method shortcut postlink executed in ascending order. that being said, don't know code making guess, sounds service more appropriate directive, unless calcul you're doing done directly in directive element, in case using $element should enough. should not pass id or selector directive.

here task. every second backgrounder task should generate json based on data. operation not cpu intensive ( network) , generates json content (5-10kb). operations take 200ms. also have 1000 clients asking content once every few seconds. let's it's 200 requests/sec. server should output current actual json. currently have rails 4+nginx+passenger+debian sever doing other jobs, related work. being student want make server in cost-effective way having ability easy-scale in ways: adding few more backgrounder jobs, generating more json's increasing number of requests 10 000 per second currently have linode 2048 ssd 2 cpu cores. questions are: what gem/solution should use backgrounder tasks ( written in ruby ) how effectivly store actual json , pass backgrounder(s) rails/nginx. how make serving json fast possible. you mentioned "server should output current actual json", guess json generation may not become bottleneck can cache memcache...

so have parent class: class table { protected static $table_name; protected static $tbl_columns=array(); public static function instance($row_from_db){ $object=new self; foreach (self::$tbl_columns $key=>$property){ $object->$property = $row_from_db[$property]; } return $object; } } when call "instance" method in child class of class table generates object of class table not object of child class. is there way code? or advice on how solve it? thanks since php 5.3.0 use late static bindings : $object = new static; foreach (static::$tbl_columns $key=>$property){ this works: $class = get_called_class(); $object = new $class; foreach ($class::$tbl_columns $key=>$property){

i have wave files (.wav) , need convert them in base64 encoded strings. guide me how in python/c/c++ ? python the easiest way from base64 import b64encode f=open("file.wav") enc=b64encode(f.read()) f.close() now enc contains encoded value. you can use bit simplified version: import base64 enc=base64.b64encode(open("file.wav").read()) c see this file example of base64 encoding of file. c++ here can see base64 conversion of strings. think wouldn't difficult same files.
