could please tell me why have waiting mouse cursor in gwt application if page not loaded ? doesn't happen on dev server. happens in production. it's happening in chrome doesn't in ie. link app here . screenshot i checked again in chrome, me no wait cursor displayed. think, google chrome trying open google translate menu. me came , page loading stopped , mouse @ normal position. i prefer try updating chrome. i have checked same in co-workers laptop , working fine too. if problem still persists, please use ccleaner software , clear temporary files, browser cache, recent files etc. why because, gwt creates lot of temporary files may reduce system performance. after each cleaning, restart system also. had few such resolutions recently.

someone building app us, provided me code go through it, , noticed this, @ first seems ok, , nice let collection manage data after while started thinking possible pitfalls in idea so: practice fetch collection's data it's own initialize method. for example: var book = backbone.model.extend({}); var books = backbone.collection.extend({ url: '/books', initialize: function(){ // logic here // if collection empty, fetch server if(this.size() == 0) this.fetch(); } }); i ask because feel might problem in following situation: suppose in routeaction: books: function() { var books = new books(); var booklist = new booklist({ collection: books }); } isn't situation possible failure, if fetch faster initialization of view, view have bound reset event, reset have triggered way before initialize of view had been executed? am wrong on this, or should submit ticket fixed. while in practice i

i'm developing social network. users may register , share twitter username (if want). wherever user posts comment or other content, username displayed. display follow @usertwitter button, if user has set twitter account. now, works, problem validate user owner of twitter account. right user entering valid twitter account! maybe using twitter api? you can set app twitter client, way user has log twitter authorize app, thereby verifying twitter identity. this couple years old might enough started: http://www.1stwebdesigner.com/tutorials/twitter-app-oauth-php/

i've been browsing lot of perl c library extensions , have noticed, in date::calc, z_int , z_long , standard (vs 'int' , 'long'). i'm assuming posix standard google has failed me while trying find definition or source syntax. know comes from, or have reference this? thanks. it's not standard thing; think it's steffen beyer 's personal notation uses in number of modules (including date::calc ). z here math sense of z denote set of integers; z_int signed int , whereas n_int (from n , set of natural numbers) unsigned int . these typedef s defined in the header file toolbox.h in modules use them.

inside django view, create subject that: subject = _(u"%(user)s has posted comment") % { 'user': user } then pass subject function, handles email notifications: send_notifications(request, subject, url) in send_notifications, iterate on subscriptions , send emails. however, each user can have different language, activate user's language dynamically via django's activate: def send_notifications(request, subject, url): django.utils.translation import activate s in subscription.objects.filter(url=url): activate(s.user.userprofile.lang) send_mail(subject, render_to_string('notification_email.txt', locals()), settings.server_email, [s.user.email]) the template gets rendered in correct language of each user. however, subject passed evaluated , translated string send_notifications , thus, not translated. i played around lazy translations , lambda functions parameters, without success. appreciated :) instead o

i'm using google maps api v3 , displaying basic map 250 place markers kmz file. i'd add search box page allows users search specific item in kml. i'm pretty sure possible, not sure best way started... pointing me in right direction appreciated. thanks. as understand, kmz file zipped file containing .kml file , other related files. reading kml , extracting values trivial using jquery , can information how here. http://think2loud.com/224-reading-xml-with-jquery/ i've not done unzipping file in javascript, can check out stackoverflow question if want on client side. unzipping files alternately, can unzip kmz file on server, , let client code kml file using ajax (as shown in first link). hope helps.

when not using symfony, use adodb querying databases. have of queries executed in file. each select statement accompanied select count statement , using binding parameters. make sure there count , if count zero, appropriate error message displayed. if there count greater zero, select statement performed. on hosting , other shared hosting sites, select count gives me value , use substr count, on client's virtual dedicated server w/plesk, weird happens. here example below: $selectcountsql = "select count(*) thistable email = ? , pwdhash = ?"; $selectcountquery = $db->execute($selectcountsql,array($email,$pwdmashed)); $count = substr($selectcountquery,10); on other clients' sites w/shared hosting, output of $count integer actual count of records. however, on client's site hosted on virtual dedicated hosting, when i: echo $selectcountquery variable, displays value count(*) 1 --e.g. if count of 1 record returned. echo $count variable, displays nothing.

ipad app setup: scenea contains layera - 1024x768. push button in layera, layerb drops down on top using ccmoveto action. layerb 800x600 can see layera behind (think of overlayed pause screen type effect). layerb contains 800x600 sprite user can zoom in on pressing button. zoom effect combination of ccscaleto , ccmoveto keep centered on part it's zooming in on. however, when sprite scales, layerb overtop of layera. there way scale sprite within contained window? layerb should use gl_scissor_test trim outside of itself. can google more information it, defines rect , uses glscissor on remove outside. have class extend when need this, goes follows: // // ccnodeclip.h // // created ignacio orlandoni on 7/29/11. // #import <foundation/foundation.h> #import "cocos2d.h" @interface ccnodeclip : cclayer { } -(void)previsit; -(void)postvisit; @end - // // ccnodeclip.m // // created ignacio orlandoni on 7/29/11. // #import "ccnodeclip.h"

i use datetick('x','hh:mm:ss.fff'). how can specify how many labels (specially denotes points) on x-axis puts? datetick replaces labels of current tick marks formatted date/time strings. you control actual location of ticks using axes properties xtick, ytick, ztick: vector of data values locating tick marks set(gca,'xtick', [1 4 6]);%sets ticks @ x=1, x=4, x=6 gca "get current axes", change xtick locations on recent axes you've activated (created, clicked on, or else). if have axes handle set of axes, can use handle in place of "gca".

i have multithread layout there manager object , lot of workers objects. i have doubt in layout better use: 1 - workers run in loop , ask "new job" manager after finished. or 2 - manager give new jobs workers after finish each job. are there recommendations this? this question have wrestled many times. each time have chosen specific situation coding for. should same. however, chose correctly must study 2 approaches carefully. consider test case. you have thousands of files process. 1. workers in control. the manager becomes queue of of files process. create fixed number of worker threads request next file manager , repeat until list exhausted. consequences you end having synchronize access queue. you can tinker number of workers attain maximal throughput hardware architecture. sometimes can dynamically adjust number of workers depending on current load can tricky. if successful can achieve exceptionally optimal sol

i understand value of exponents, typically when displaying decimal values end user, it's easier layman understand normal decimal values. when perform following, i'd rather display value of decimal 50 , instead of: >>> decimal('22679.6185') / decimal('28.349523125') / 16 decimal('5e+1') is possible without quantizing or doing modify actual value? also, why display short value exponent , longer values in normal decimal form? product of division (irony intended)? see: significant figures in decimal module (which admittedly tells use .quantize()). main problem must keep track of number of significant digits manually.
