this question has answer here: why `pattern.test(name)` opposite results on consecutive calls [duplicate] 4 answers i able work around issue turned out didn't need /g. wondering if able explain why following behavior occurred. x = regexp( "w", "gi" ) x.test( "women" ) = true x.test( "women" ) = false it continue alternate between true , false when evaluating expression. issue because using same compiled regexp on list of strings, leading evaluate false when should have been true. when use g flag, regex stores end position of match in lastindex property. next time call of test() , exec() , or match() , regex start index in string try , find match. when no match found, return null, , lastindex reset 0. why test kept alternating. match w , , lastindex set 1. next time called it, null returned, , last

i'm using three.js create interactive web application, , i've run little stumbling block: i have number of canvases contained in draggable divs on page. in each canvas hope display unlit 3d object different material applied (each material using custom shaders). of materials work off same texture (one might blue-tinted, 1 might desaturated, etc.). the number of canvases on page can vary, expect number commonly reach/exceed 20 canvases, , such sharing resources (particularly large textures) beneficial. up until have been using multiple renderers, cameras , scenes has worked fine until started trying use same texture in multiple scenes. most of materials share uniforms , attributes avoid having duplicate information, , of materials stay in sync 1 (e.g. when of materials change on time should change in same way). i wondering if there way able share textures between scenes/renderers/canvases? when try following error: webgl: invalid_operation: bindtexture: object not

i'm having strange issue using tables rmi. client implementation of time slot booking system, i've implemented table. i'm faced 2 problems. first 1 causing table update after change had been made. solution seemed private void cleanup() { panel.removeall(); panel.setvisible(false); panel.revalidate(); showtable(); } and appear working. (or maybe causing issue, i'm not sure) the problem have jtextfield inside method calls actual booking. private jtextfield txtclientname; txtclientname = new jtextfield(); txtclientname.settext("clientname"); and in confirm button listener - callbookingslot(buttonaction, txtclientname.gettext()); the strange thing works initially, once. working mean putting correct value extracted jtextfield table. first time round put in value of user typed in field. subsequent goes , put in string "clientname" anyone have ideas? issue doesn't appear rmi related, i've tried without r

i have complex view, let's complexview , consists of 10 labels, 2 buttons, 2 large images , need create many times (scrolling, fast scrolling!) - texts , images different in 2 different complexview views. currently creating each complexview instance programmatically. 1) wonder if there techniques speed process of creating uiview each time? 2) option see experiment: create xib-file particular view , extract generic part of view there - benefit that? update: similar question detailed explanation of seamus campbell said here in accepted answer: how reuse/recycle custom element uitableviewcell does? the best way achieve high performance displaying complex views take uitableview approach , re-use offscreen views rather creating new ones. simplest way use table view , custom cells, it's possible roll-your-own if table view's assumptions don't make sense.

i have latest kinect sdk, xna 4.0, , model skeleton , i'm looking working kinect create simple games. heard various engines, such digitalrune engine provide easy way map skeleton generated kinect sensor skeleton of model. which engine best task , why? i'd prefer if list both best free engine , 1 have pay for, additional suggestion, should have them. i need this. while did manage find 5 engines might suit needs (ploobs, engine nine, digitalrune, hilva, xen, xna final engine) have no way of telling better other, there little activity in related forums , don't have time (or, more importantly, knowledge) test these engines. i think xna better, because gives more transparency when comes game programming, there no doubt used game programming , plus point have tons of tutorials. xna framework best can have e-books too.

to test in app billing, said need factory reset , specify test account when device boots up. i have configured 2 google accounts , can somehow test account active transactions , revert original when done in-app billing testing ? i not able understand need factory reset test in-app billing when can set multiple google accounts. after looking around factory reset way change device account. there issue problem on android market in-app billing i'm guessing cant use personal account because same developer console account (which google doesn't allow). however, if using personal account on device change developer console account . this means test personal account avoiding factory resets.

i trying push notification phongap. i followed following tutorial http://www.pushwoosh.com/programming-push-notification/android-gcm-push-notifications-guide/ but there need have google project id , pushwoosh app id . process these ids..??? any appreciated! this guide shows can find google project id: http://www.pushwoosh.com/programming-push-notification/enabling-gcm-services-for-google-api/ pushwoosh app id application code (xxxxx-xxxxx) can find on application page in pushwoosh control panel.

how can stop whole app in simple terms? (all activities, services, threads, etc. everything) life-cycle callbacks (especially onstop() , ondestroy() ) should called. google suggests following possible solution: kill process: wouldn't call lifecycle callbacks and finish(); 1 activity: but possible access method outside like: //getting activityies, how? //for each gotten activity acitvityname.finish(); or via or via getparent().finish(); ? this did not me: best way quit android app? fd use broadcast receiver call activities , call finish locally in them, invoking current lifecycle callbacks. broadcastreceiver , paused activity http://developer.android.com/reference/android/content/broadcastreceiver.html

i have sparse 3d volume (cube), @ each x,y location want create sphere radius r, center located @ x,y,z. each sphere want compute center of mass. my questions: the points within each sphere not evenly distributed, center of mass not centroid, how compute center of mass ? found many different ways... i need compute @ each size(x)*size(y) times, can quite large, can create 3d sphere this: w = ceil(r)*2+1; [x,y,z] = meshgrid(1:w,1:w,1:w); xc = floor(w./2)+1; yc = floor(w./2)+1; zc = floor(w./2)+1; mask = (x-xc).^2 + (y-yc).^2 + (z-zc).^2 <= r.^2; mask = double(mask); but make me go loop each point, , time consuming. matlabit take @ update step of k-means clustering , find center of mass sphere. to find points should included in sphere calculate , threshold euclidean distance between centroid of sphere , each point. if distance less sphere's radius include it. do in 3 deep nested loop on set of x,y,z sphere centroids, , you're done.

i looking @ dart api find way listen keyup event using capture mode. new stream system there's no parameter specify capture anymore: document.body.onkeyup.listen(callback); // where's old "usecapture" parameter? to achieve same thing streams, here's example: element.keyupevent.fortarget(document.body, usecapture: true).listen((e) { // stuff. print('here go'); }); the method used above, creates stream capture mode. stream interface ( listen() method) quite generic, , can't have specific functionality looking for.

i using caroufredsel plugin responsive images, slider getting full height of images (before resized) , leaving big gap @ bottom. the function being called within window.resize function because need check width of window. need because number of items shown has vary, , if window below width have destroy carousel , show items. here code: $(document).ready(function(){ $(window).resize(function(){ var numitems; var width = $(window).width(); if(width >=769) { numitems = 5; } else { numitems = 3; } var carousel = $("#carousel"); $("#carousel").caroufredsel({ responsive : true, scroll : 1, items : { visible : numitems, width : 200 }, oncreate : function () { carousel.parent().add(carousel).css('height', carousel.children().first().height() + 'px'); } }); if (width <=480){ $("#carousel").trigger("destroy"); } }).resize();//trigger resi

i made simple design in .xib , deployment target app ios 5 view doesn't resizes, when run app in simulator or device. here snapshot of .xib file.. when try run app in simulator, runs in simulator of 4", not resizes, when run app in simulator of 3.5". autoresize subview property checked. here snapshot of simulaotrs , first screenshot 3.5" , second 4".. thanks in advance. if want autoresize , autoorder icons referencing upper view, try play either layout tab or create each layout own .xib ;)

when using app engine datastore storing entities, applied technique caching. i mean, without caching do, this: datastoreservice _ds = datastoreservicefactory.getdatastoreservice(); public void put(string key, string value){ try { entity e = new entity(createkey(key)); e.setproperty("key", key); e.setproperty("value", value); _ds.put(e); } catch (exception e) { // handle exception } } so caching kicks in? how caching play during methods. update: simply put question when caching. basic implementation not caching @ all, plain put , datastore. should caching implemented on lowest level api in code or in high level api, in case, lowest level api have this, put , datastore. there 2 kinds of caching think in app engine: memcache ds entities , edge caching static assets. video google covers both nicely specific code examples: google i/o 2012 - optimizing google app engine app for edge caching

i looking @ html5 demo of bin 'eats' in list . want modify 'eat' of items , others rejected. the code here: http://html5demos.com/drag this code works in ie requirement. tips appreciated. being impatient found way this.. <ul> <li><a draggable="true" id="one" href="#">one</a></li> <li><a draggable="true" href="#" id="three">two</a></li> <a draggable="true" href="#" id="trick">trick</a> <li><a draggable="true" href="#" id="four">four</a></li> <a draggable="true" href="#" id="five">five</a> </ul> the solution realise add tag within list. had style tag same list item. if person tries drag trick item doesn't disappear list , bin doesn't provide text response.

is there way conviniently call template operator-> ? cool have such possibility in classes variant for example: (thats example) struct base_t { template<class t> t* operator->() { return reinterpret_cast<t*>(this); } }; int main(int argc, char* argv[]) { base_t x; x.operator-><std::pair<int,int>>()->first; //works, inconvenient x<std::pair<int,int>>->first; // not work x-><std::pair<int,int>>first; //does not work return 0; } i need proofs =) no, it's not real, how it's not real too struct base_t { template<class t> t operator () () { return t(); } }; int main() { base_t x; x.operator ()<int>(); // works x.()<int>(); // not works } expression x->m interpreted (x.operator->())->m class object x of type t if t::operator->() exists , if operator selected best match function overload resolution mechani

there method in code igniter under system/core/common.php called load_class (). i overwrite method. overwrite code igniter class create file such my_common.php in case common.php collection of methods , there no classes encapsulates them. so how do this? there's no officially supported way built in extending mechanisms. consider other way achieve goal. however functions inside common.php wrapped inside if checking if function exists or not can following: create my_common.php put somewhere in project (maybe application/core/ mirror other similar extends) open index.php file in root of project insert include apppath.'core/my_common.php'; before closing require_once basepath.'core/codeigniter.php'; line now if have have load_class function in my_common.php shadow original version.

i want json_encode return this [{key: "value"},{key:"value"},...] instead this: {"1": {key: "value"}, "2": {key: "value"}, ...} the result fine until did array_filter ... strange... function somefunction($id, $ignore = array()) { $ignorefunc = function($obj) use ($ignore) { return !in_array($obj['key'], $ignore); }; global $db; $q = "some query"; $rows = $db->givemesomerows(); $result = array(); if ($rows) { // mapping i've done $result = array_map(array('someclass', 'somemappingfunction'), $rows); if (is_array($ignore) && count($ignore) > 0) { /////// problem after line //////// $result = array_filter($result, $ignorefunc); } } return $result; } so again, if comment out array_filter want json_encode on whatever somefunction returns, if not json-object.
