is there way re-direct user ios mobile app passbook enter credit card apple pay? for example, can mobile banking or credit card application credit issuer -create button direct user add credit card apple pay? presume require launching of passbook appropriate place add credit card in passbook. think physical card still required. you can't detect whether user has card or not (at least, there's no documented way; credit card issuers might have access special api). user doesn't physically need card add it. you can open passbook app so: [[uiapplication sharedapplication] openurl:[nsurl urlwithstring:@"shoebox://"]]; however, isn't documented, , might break in future versions of ios, settings url scheme broke in ios 6.

i have java code class variables , rather set them particular value, i'd initialize zero. in c/c++, can memset() on size of structure, how do same thing in java? primitives default zero. objects default null. see https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html . however, article mentions, relying on default value in java considered bad practice. better practice set them either when declare them or in constructor.

using gorelic plugin, i've noticed virtual memory on heroku dyno steadily climbing though memory usage looks fine. virtual memory never appears exceed 1000m, when gets close start notice performance degradation. i've used pprof profile memory usage of app , looks it's free of leaks. also, i've read suggests go reserve large blocks of virtual memory , it's nothing worry about. is possible large virtual memory usage affecting performance on 1x heroku dyno? need use 2x dynos because go memory hog? possible configure go uses less virtual memory? thanks!

i have following function. javascript tutorial i'm reading says should output 2, i'm getting undefined in text editor (js fiddle). what reason? have strict mode vs non-strict mode? function foo(){ console.log( this.a ); } var = 2; foo(); //should output "2" i'm getting undefined. why? that's because running code in function wrapper jsfiddle creates. default onload puts code in function runs on load event. that makes a variable local function, , not global variable. when try access using this.a variable in window.a (as this point window object), variable not global can't found there. if choose no wrap - in <head> or no wrap - in <body> put code, 2 output.

in javasscript, use settimeout repeatedly redraw html5 canvas. function dodraw() { drawoncanvas(); settimeout(dodraw, 20); } i have problem on android browser. (perhaps on ios, haven't tested yet...) : 1. runs ok 2. press android "home" button , someting else 3. come browser. 4. problem: settimeout not scheduled execute again. so screen refresh loop stops, , game "dead". edit: now, continued investigating. turns out settimeout still works. real problem canvas disapeard screen, , nothing draw shows. canvas blank. for rendering loops advised use requestanimationframe because knows when schedule callback, best possible time slot in browser repaint completed. using settimeout skip frames , that'll result in serious jankyy animation and far question concerned can restart loop on document load window.onload = function() {dodraw();} i hope works .

i'm playing around atom-shell , wondering if has used/written module making tubular browser windows? currently, seems, atom-shell opens new window when instantiating browserwindow : var win = new browserwindow({ width: 800, height: 600, show: false }); win.on('closed', function() { win = null; }); win.loadurl('https://github.com'); win.show(); is there way of tabularising window, in atom application? or have write functionality inside current browserwindow in order work? there no way create native tabs in atom shell. being said, @zcbenz suggests entirely doable <webview> tag, allows safely host arbitrary web content inside atom shell.

i'm doing data structures exercise , have been blocked since yesterday bus error, reckon because i'm doing bad things memory. cannot figure out exactly. these requirements have established practice: able add product (any way do) list able retrieve product in list @ current position (next, prev, movetostart, movetoend… there's cursor pointer, called "actual" here) any changes retrieved product should updated in data structure (ie. list::retrieve(*product), product->visits++) this code have. apologies var names, have in spanish , therefore names in spanish. class producto { // product public: string marca; double precio; int visitas; int compras; producto () {} producto (string m, double p, int v = 0, int c = 0) : marca(m), precio(p), visitas(v), compras(c) {} }; class nodo { public: producto valor; // value nodo *siguiente; // next nodo *anterior; // prev nodo (producto p, nodo *a = null, nodo *s = null)

i have viewpager actiontabs each action tab has own layout. in 1 of layouts have button when clicked asynctask changes background color should executed shown below. at run time receive below errors logcat. please have @ logcat errors , kindly let me know missing in code. code class asynccolor extends asynctask<string, integer, string> { @override protected void onpreexecute() { // todo auto-generated method stub super.onpreexecute(); } @override protected string doinbackground(string... params) { // todo auto-generated method stub (int = 0; < params.length; i++){ rl_3.setbackgroundcolor(color.parsecolor(params[i])); } return "done"; } @override protected void onprogressupdate(integer... values) { // todo auto-generated method stub super.onprogressupdate(values); } @override protected void onpostexecute(string result) { //

so trying out shiny, , have problem. what want selectinput can select different option , graph. these different graphs ggplot2 graphs created in source file. graphs have called. not seem figure out how that. graphs ggplot2 graphs , fine, load perfectly, assume that not problem. i want have text output depends on selectinput. so here server script: shinyserver( function(input, output) { output$map <- renderplot({ plot <- switch(input$activity, "" = null, "act1" = plot1, "act2" = plot2, "act3" = plot3, "act4" = plot4, "act5" = plot5, "act6" = plot6) plot }), output$text1 <- rendertext({ text <- switch(input$activiteit, "" = null, "act1" = paste("blabla"), "a

i tried implement @controlleradvice globally handle general exceptions related web application. wanted send wrapped json response response status set accordingly. here code sample. @controlleradvice public class globalerrorhandler { @responsestatus(httpstatus.bad_request) @exceptionhandler(exception.class) @responsebody public response handleallerrors() { response wrapped = new response(httpservletresponse.sc_bad_request, "error"); wrapped.setmessage("could not retrieve data"); return wrapped; } } response pojo used wrap response. problem is, despite @responsestatus annotation, response has status code 500 (internal server error) default error page showing stack trace. @responsebody seems not work. documentation states send json response on @exceptionhandler method. don't understand i'm doing wrong in here. i'm using spring 3.2.8 release framework , gson used message conversion, if matters. a

i read sift, surf, fern, brift , evolution algorithms. not sure algorithms best. need help. of course know each algorithms have own advantages, here key classify: which fastest in training/ recognize phases? which consume fewest memory in runtime? which can implement detect 3d object? thank you, , sorry bad english. in case, want implement application on smartphone recognize known object . your question bit complicated. there no optimal methods cases methods suit specific cases. if decide use local descriptors in method advise started using sift / surf popular descriptors not efficient (slow) , require lot of memory. after that, can try replace them binary descriptors (eg. brief, orb, brisk, freak) more efficient , require less storage. but said before depends on want implement, , requirements of application.
