i'm writing web application needs transfer date between java , javascript. firstly, used milliseconds exchange date, mentioned here: https://stackoverflow.com/a/1007854/4675827 . however, there problem when came across dst, named daylight saving time. millisecond value java , javascript different sometimes. when store date part of date, saved time as: "2015-10-15 00:00:00", when pass millisecond value javascripts, became "2015-10-14 23:00:00". thus, date part has 1-day difference. i'm wondering what's best practice exchange date data between java , javascript, or can turn off dst in java? thanks in advance! finally, i able disable dst changing timezone settings of jackson mapper, used serialize , deserialize json objects. i changed gmt+8, beijing time. doesn't use dst @ all. mapper.settimezone(timezone.gettimezone(zoneid.of("gmt+8"))); you don't provide criteria "best practice", robust way transfer

i'm writing object factory node module in es6. i'm using stamptit library https://github.com/stampit-org/stampit base objects started enhance them , return own objects through factory. lets have these 2 files in '../../models/': mybasejsondata.json { "addresses": { "type": "addressjsondata.json", "multi": true, "required": true }, . . . } addressjsondata.json { "street_name": "sample", "zip_code": "75024" . . . } this current code comments: import stampit 'stampit'; import * fs 'fs'; // allows me run node's async internal functions generator function runnodefunc( gen, iter) { (iter = gen((err, data) => (err && iter.throw(err)) || iter.next(data))).next(); } // loop through object's keys , values function* objectentries(obj) { let propkeys = reflect.ownkeys(ob

i have base user model object. each user can either staff member, parent or student. each account type has associated model. for example: class user extends model { public function details() { switch($this->account_type) { case 'staff': return $this->hasone(staff::class); case 'student': return $this->hasone(student::class); case 'parent': return $this->hasone(parentuser::class); } return null; } if run: echo $user->details->staff_code; then outputs crs example. however, if run object_get() : object_get($user, 'details.staff_code'); then outputs null . i figured because in object_get() method, has line: if (! is_object($object) || ! isset($object->{$segment})) i assume because details property magic/dynamic laravel model property, isset() doesn't work on it. whats best way handle this? safe edit object_get() method , r

i'm using silex's internal forwarding map public urls internal urls i.e. my.domain.com/something serves my.domain.com/something_else using $subrequest = request::create( $redirect, $method, [], // params $request->cookies->all(), $request->files->all(), $request->server->all() ); if ($request->getsession()) { $subrequest->setsession($request->getsession()); } return $app->handle($subrequest, httpkernelinterface::sub_request, true); however, in chrome's inspection tool, appears 301 resulting page, serves result. "by design" represents interesting security problem? there ways around limitation? while can't post code something_else route controller, gist is // controller provider $controller_factory->match('/something_else/{param}', function(...) { include 'path/to/some/file'; }); and // some/file - prepares file downloaded ... return new binaryfileresponse();

if use double pointer instead of single pointer code working properly.. node *pairwiseswap(node *start) { node *prev=start,*current=start->next; if(start==null || start->next==null) return 0; while(true) { node *next=current->next; current->next=prev; if(next==null || next->next==null) { prev->next=next; break; } prev->next=next->next;**//next next** prev=next; current=prev->next;**//appending nodes previous one** } return start; } node *prev=start,*current=start->next; if(start==null || start->next==null) here's problem. if start==null error when doing current=start->next , since trying dereference null pointer i assume trying on linked list, , want return 0 (a null pointer) in case list has 1 element. if case, it's enough swap first 2 instructions of function

i new rmi please forgive me if question silly. trying export data in concurrent manner. how can reuse same port exporting more 1 remote object @ once. can guide me achieve example? i tried first object got exported got following exception @ time of second export. java.rmi.server.exportexception: port in use: 55580; nested exception is: java.net.bindexception: address in use: jvm_bind i used following code snippet unicastremoteobject.exportobject(remoteobj, 55580); if skipped port number port number picked rmi. below unicastremoteobject.exportobject(remoteobj) in case port number fixed application. how can reuse same port exporting more 1 remote object @ once that's happens default. remote objects exported same jvm that don't specify port number, or specify port zero, and don't specify server or client socket factories, or specify same socket factories determined equals() will exported on same port. i conclude must exporting remot
