i have problem when adding card app , when card set go details. there time new card generated. works fine generate new card , go detail, time generate new card not since then, fixed moment. example, time generate new card 30 , starts @ 15. looks takes on time of first card. not know why happening.

public class carddetailsactivity extends appcompatactivity {

mysharepreference mysharepreference; private string intervaltotpencrypt; private progressbar progressbar; private textview secondtimetextview; private int interval; protected string  intervaltotpdecrypt; private imageview myimageview;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_card_details);      textview titletextview = (textview) findviewbyid(r.id.toolbar_title);     titletextview.settext(cardnamedecrypt);      textview dottextview = (textview) findviewbyid(r.id.dottextview);     subtitletextview.settypeface(custom_fonts);     second_text.settypeface(custom_fonts);     setsupportactionbar(toolbar);      progressbar = (progressbar) findviewbyid(r.id.refershprogrss);     myimageview = (imageview) findviewbyid(r.id.qrcodeimageview);     mysharepreference = new mysharepreference();      bundle extras = getintent().getextras();     intervaltotpencrypt = extras.getstring("intervaltotp");     keystring = mysharepreference.getkeystring(carddetailsactivity.this);     typeface custom_fonts = typeface.createfromasset(getassets(), "fonts/opensans-regular.ttf");     toolbar toolbar = (toolbar) findviewbyid(r.id.toolbar);     toolbar.setnavigationicon(r.drawable.ic_arrow_back);      try {         intervaltotpdecrypt = aescrypt.decrypt(keystring, intervaltotpencrypt);     } catch (generalsecurityexception e) {         e.printstacktrace();     }       interval = integer.parseint(intervaltotpdecrypt);      localbroadcastmanager.getinstance(this).registerreceiver(mmessagereceiver,             new intentfilter(progressbarservice.download_action));      intent intent = new intent(this, progressbarservice.class);     intent.putextra("interval", interval);     startservice(intent);      progressbar.setmax(interval);     progressbar.setprogress(interval);  }  @override protected void ondestroy() {     super.ondestroy();     localbroadcastmanager.getinstance(this).unregisterreceiver(mmessagereceiver); }  private broadcastreceiver mmessagereceiver = new broadcastreceiver() {     @override     public void onreceive(context context, intent intent) {         if (intent != null) {             int progress = intent.getintextra(progressbarservice.percentage_stamp, 0);             progressbar.setprogress(progress);             secondtimetextview.settext(" " + progress + " ");         }     } };

}

my progressservice.class 

public class progressbarservice extends service {  private int interval; private intent intent; private localbroadcastmanager broadcastmanager; public final static string percentage_stamp = "percent"; public final static string download_action = "com.magdad.apk.download";  public progressbarservice() { }  @override public void oncreate() {     super.oncreate();     broadcastmanager = localbroadcastmanager.getinstance(this); }  @override public int onstartcommand(intent intent, int flags, int startid) {      if (intent != null) {         interval = intent.getintextra("interval", 0);     }      new updateprogressbar().execute();     return start_sticky;  }  @override public ibinder onbind(intent intent) {     // todo: return communication channel service.     throw new unsupportedoperationexception("not yet implemented"); }  private class updateprogressbar extends asynctask<void, integer, integer> {      @override     protected void onprogressupdate(integer... values) {         super.onprogressupdate(values);         intent = new intent(download_action);         intent.putextra(percentage_stamp, values[0]);         broadcastmanager.sendbroadcast(intent);     }      @override     protected integer doinbackground(void... params) {         (int = interval; >= 0; i--) {             publishprogress(i);             try {                 thread.sleep(1000);             } catch (interruptedexception e) {                 e.printstacktrace();             }         }          return null;     }      @override     protected void onpostexecute(integer integer) {         super.onpostexecute(integer);         new updateprogressbar().execute();     } }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
