this has been bugging me week now. i cant seem large php array persist in session on page redirect. for ($i=1;$i<$data['weeks'];$i++) { $instances[] = array( 'start' => $starttime + ((86400 * 7) * $i), 'end' => $starttime + ((86400 * 7) * $i) + $duration, 'venueid' => $data['venueid'] ); } $request->getsession()->set('addclass-1-instances', $instances); return new redirectresponse ($this->generateurl( 'class_add', array( 'clubid' => $this->club->clubid, 'step' => 4, 'classtype' => 1 ) )); this works when array small (1-10 elements) fails when larger (1000 - 2000 elements). if dump out session object after adding it, can see in session attributes collection. var_dump($request->getsession()); protected 'attributes' => & array (size=6) 'addclass-1-instances

i have listbox on windows phone app, listbox receive values collection. put listbox items on array. so, need value first list item, received value app1.pivotpage1+fields . the collection item want show fnome . how it? my code: private void button_click(object sender, routedeventargs e) { string[] array = new string[list2.items.count]; (int = 0; < list2.items.count; i++) { object s = list2.items[i]; array[i] = s.tostring(); } tjsonobject jobject = new tjsonobject(); tjsonpair jpair = new tjsonpair("test", array[0]); tjsonpair jpair1 = new tjsonpair("test1", "test1"); tjsonarray jarray = new tjsonarray(); jobject.addpairs(jpair); jobject.addpairs(jpair1); jarray.add(jobject); messagebox.show(jarray.tostring()); } my collection: public observablecollection<fields> items { get; set; } public class fi

is possible load added module @ run-time? i have added optional module ear, started jboss , added optional module @ run-time using cli. load module though had restart jboss not looking for. is there way load without restart using jboss cli? you can try jrebel , hot deploy stuff have trial version. if using jboos 7.0.1 (community project). you can go jboss administrative panel, there in profile settings open core - deployment scanners. turn on auto deploy-exploded (set true), , set scanner time per requirement ( default 5000 ms) . it.

say have: class mycreate(createview): template_name = 'template.html' success_url = reverse_lazy('blabla') form_class = myform and suppose in template want add back button. lead me same page success_url . solution override get_context_data in mycreate class , add {'back': self.get_success_url()} context . the implications have more createviews , had create contextmixin back button. there other easier solution? accessing success_url directly in template? thanks as can see in django (1.7) implementation of contextmixin , must have access view instance our templates: def get_context_data(self, **kwargs): if 'view' not in kwargs: kwargs['view'] = self return kwargs so can access success_url in templates: {{ view.get_success_url }}

when click textbox datetimepicker popups after when click outside of picker close it, page postbacks textchange doesn't fired. either should not postback page or textchange fired fix here. know how solve problem? <script> $(function () { $("#<%=dpstartdatetime.clientid%>").datepicker({ autoclose: true, weekstart: 1, language: "tr" }).next().on(ace.click_event, function () { $(this).prev().focus(); }); }); </script> <asp:textbox id="dpstartdatetime" runat="server" cssclass="form-control date-picker" data-date-format="dd.mm.yyyy" autopostback="true" ontextchanged="dpstartdatetime_textchanged"></asp:textbox><span class="input-group-addon"><i class="fa fa-calendar bigger-110"></i></span> change autopostback="true" `autopostback="false"'

i'm trying grid (created angular directive) populated data, not populating. here's grid declaration: <div id="daytypesgrid" kendo-grid k-options='daytypesgridoptions'></div> here's code angular controller: $scope.daytypesgridoptions = { schema: { model: { id: "description", fields: { description: { editable: false, nullable: false }, numberofdays: { type: "number", validation: { required: true, min: 0} } } } }, columns: [{ field: "description", title: "day type" }, { field: "numberofdays", title: "number of days" }] }; so far good. grid instantiated, , see 2 columns. , angular controller executes data fetch call, , store result in array $scope.viewmodel.daytypes. using browser dev tools, can see $scope.viewmodel.daytypes indeed contains

i'm testing communication between node.js , executables launched child processes. executable launched within node.js via child_process.spawn() , output monitored node.js. i'm testing capability both on linux , windows oss. i've spawned tail -f /var/log/syslog , listened output, own executables can't seem write correctly stdout (in whatever form exists when captured node.js). test code: #include <iostream> #include <stdio.h> #include <unistd.h> int main() { using namespace std; long x = 1; while (true) { fprintf(stdout, "xtime - %ld\n", x++); usleep(1000000); } } (note: include s may useless; i've not checked them) stdout output not automatically flushed (at least on *nix) when stdout not tty (even if there newline in output, otherwise newline flushes when stdout tty). so can either disable stdout buffering entirely via setbuf(stdout, null); or can manually flush output

i using blue-daemons fork of daemons gem (since second 1 looks totally abandoned) along daemons-rails gem, wraps daemons rails. the problem daemon eats cpu when it's idle (10-20 times higher it's performing job). by being idle, mean have special flag - status.active? . if status.active? true , perform job, if it's false , sleep 10 secs , iterate next step in while($running) do block , check status again , again. i don't want hard stop job because there sensitive data , don't want process break it. there way handle high cpu usaget? tried sidekiq, looks it's primary aim run jobs on demand or on schedule, need daemon run on non-stop basis. $running = true signal.trap("term") $running = false end while($running) while status.active? ..... lots of work ..... else sleep 10 end end

i have uitableview , have set datasource table using 'list'.i know size of list , have set number of cells of table same list length.i fetching data table in background meaning list data changes dynamically when table being displayed. when there fast swipe user,the tableview displays empty cells data still being fetched. issue: when reach end of tableview , when tableview still displaying empty cells,and try scroll cell redrawn bottom showing data meaning data 'refreshed' bottom of tableview. what tried: tried reloading tableview,reloading cells data backend,but still issue persists.i tried reloading tableview using invokeonmainthread,but still problem persists. what think happening: data fetching completed in background when tableview displaying empty cells , when scroll again cells 'repainted' display data.i using reusable cells in tableview. is there way reload cells data , update cells.that is,when tableview displaying empty cells , data fetching

i read uint8_t , uint16_t types registers "cast" them floats. wich optimal way? there's no need cast; integer types implicitly convertible floating-point types. uint8_t u8 = something; uint16_t u16 = whatever; float f1 = u8; float f2 = u16; 8 , 16-bit integer values should represented exactly. larger types might lose precision.

can please explain in situation supposed use arraylist instead of simple array , diffrence between these 2 , how intialise arraylist.i new java use example if possible whenever don't know size created, can use arraylist.. if want speed access, can use array. (indexing in array faster arraylist).. and , arraylist reduces complexity of coding... arraylist can initialized creating object arraylist class arraylist al = new arraylist(); al.add("string"); || al.add(number); can used add values arraylist..

the new iphone 6 has been announced, , there multiple posts number of pixels , pixels per inch. that's great, ignores important question developers don't seem finding anywhere. what's addressable screen size? for example, iphone 5 has 4" screen 1136x640 pixels. cool. if i'm programming it, addressable screen size 568x320. if draw line 0,0 568,320 (in landscape mode, full seem, of course) goes across entire display, not half of it. the iphone 6 has 2 new pixel sizes, 1334x750 , 1920x1080 iphone 6 plus. presumably, means addressable screen space programming 667x375 iphone 6 , 960x540 iphone 6 plus. can confirm that? also, simulator has variable size setting, doesn't come preset new iphones. set simulator 1334x750 or 567x375 set layouts iphone 6? the iphone 6 has scale of 2 point size 375 x 667 (not 375 x 567). the iphone 6+ has virtual pixel size of 1242 x 2208 scale of 3. point size 414 x 736.

what best way display block of scrollable text in spritekit game? within scene. write own algorithm using sklabels seems there should better way. there no component in spritekit out of box, it's quite simple simulate scrolling text handling touches. you have handle limit , paging if want have bouncing, acceleration , others, there plenty of examples around here start from. keep in mind sklabelnode doesn't support multiline out of box, have create own multiline label (basically 1 label per line). if text want render long may struggle create , not smooth, work fine. the other option use uikit makes simple create using uiscrollview , uitextview , present on top of skview contains scene. doesn't work if need within scene works wonders if want display big chunks of texts instructions or legal texts.

i've been going nuts problem hours, , i've been redoing on , over! @ point think i'm seeing numbers flying around me. anyway, i'm supposed write program finds correct amount of money pay each month on 1 year, pay off debt on credit card. program, there's few conditions must met. it must done using bisection search ((low + high) / 2) there's set balance there's annual interest rate. here's code @ moment, , i'm getting infinite loops. doing wrong here? balance = 320000 annualinterestrate = 0.2 monthly_interest = float(annualinterestrate) / 12.0 lower_bound = float(balance / 12) upper_bound = (balance * (1 + monthly_interest)**12) / 12.0 epsilon = 0.01 ans = float(lower_bound + upper_bound) / 2 while abs((balance * (1 + monthly_interest)**12) / 12.0) >= epsilon: ans = float(lower_bound + upper_bound) / 2 total = float(ans * 12) new_balance = 0 interest = 0 month in range(0, 12): interest += ans + (1 + m

i have been studying leaflet chloropleth example . in leaflet application, have jquery dropdown that, when selected, fires function takes name of state argument. want use state name update chloropleth map. what pattern changing style of leaflet geojson layer? should recreate layer created l.geojson() second time? seems though layers drawing on top of each other approach. i can provide fiddle if needed. here's an example of changing choropleth classify on different properties - trick call setstyle again different values.

i having trouble script link custom actions. building sharepoint app, , added site-scope custom action pointing script file in style library, want particular script injected pages of sharepoint site. while works in situations, script link injection breaks without apparent reason under conditions. example, when arrive on root web, script injected. but, if go link within web (for example home or site contents), file supposed injected not fetched style library , therefore never injected, resulting in uncaught referenceerror when try call 1 of script's function. weirdest part page refresh through ctrl+f5 fetch script file without problem, regardless of page's ability fetch script file when first accessed. keep script until accessed through link again. i've read on sharepoint caching , thinking may cause of problem, trouble these articles talk cache-induced errors when updating file, while trying access it. one thing note that, due limitations, adding script link cu
