i want use module create connection using multiple socks proxies, module using unreliable , slow compared using external solution such proxychains. after connecting through chain of proxies, while loop begins sending data through proxy chain. however, program crashes error: "out of memory". have advice on how fix code? appreciated. while ($sock) { $sock->syswrite ( "get / http/1.1\r\n" ); } when @ wireshark capture, initial request sent without problems following requests have duplicate http requests in each packet. see: wireshark capture edit: tried using io::async, requests aren't sent. my $loop = io::async::loop->new; $handle = io::async::handle->new( write_handle => $sock, on_write_ready => sub { $request = "get / http/1.1\r\n" print $sock $request; } ); $loop->add( $handle ); $loop->loop_forever; edit: able fix script establishing new chain each request send. possible send connect request through socks

i have deal question: filter student in list result "pass". when write code in picture below, return wrong caution this: cannot implicitly convert type 'string' 'bool'. although used convert.toboolean(t.result) can't work? help me! to filter student in list result "pass" need add condition as: lst.where(t => t.result=="pass").tolist(); you can same boolean property instead string, property definition like: public bool result { { return score > 25; } } so iterative condition filtering student in list result "pass" (score > 25) lst.where(t => t.result).tolist();

using fullpage.js, created 'slides' page looks great in browser, on iphone not scale text fit screen (and it's not zoomable either). it ends looking this in css file, have font set @ 1.2em, there way make text scale more readable size on iphone? if you'd view on phone: link example thanks so for every resolution can set different css meaning. example @media screen , (max-width: 300px) { body { background-color:lightblue; } } it means if resolution not more 300 use different background body. if dont want have in same same css can link this: <link rel="stylesheet" type="text/css" href="tablets.css" media="screen , (min-width: 600px) , (max-width: 800px)">

i'm wondering why performance bad when working generic lists , arrays in java. i had below create generic array, taking on 2 seconds create array 50 elements. final t[] returnclasses = (t[]) array.newinstance(classoft, data.getcount()); after reading number of areas java.lang.reflect.array shouldn't used hasn't been optimised , use lists instead changed code below. list<t> returndatalist = new arraylist(data.getcount()); after change there no performance increase. when comparing timings creating explicitly typed list times returned 0ms what efficient way create collection (must retain order) when using generics? if makes difference method declared as public <t> list<t> method(data data, class<t> classoft) logging done below code calendar = calendar.getinstance(); list<t> returndatalist = new arraylist(data.getcount()); log.d("test", "create array time = " + (calendar.getinstance().gettimeinmillis()

i've got mvc based java application 3 models: room , student , studentroom . studentroom contains object of room , student . now i've got problem if sql query returns no result , check value of student's name this if(studentroom.student.name != null) { } i'll nullpointerexception , don't know how handle it. should set student.name = ""; since query has no result? if(studentroom != null && studentroom.student != null && studentroom.student.name != null){ //.. access student } above solution looks bit weird. should better use getter/setter methods instead of directly accessing objects. apart can define methods isstudentavailable() in studentroom check whether has student in or not. should set student.name = ""; since query has no result ? it depends on use case. must better keep null raise exception instead of passing null check validations.
