Google Maps Api add multiple custom overlays in loop -


i try add multiple custom overlays googlemaps. @ first add 2 images, following code. 

        var overlays = [];         var data = mappings[0];         var data2 = mappings[1];           usgsoverlay.prototype = new google.maps.overlayview();          var bounds = new google.maps.latlngbounds(             new google.maps.latlng(data.latnw, data.lngnw),             new google.maps.latlng(data.latse, data.lngse));          var bounds2 = new google.maps.latlngbounds(             new google.maps.latlng(data2.latnw, data2.lngnw),             new google.maps.latlng(data2.latse, data2.lngse));          // photograph courtesy of u.s. geological survey.         var srcimage = 'maps/' + data.name;         var srcimage2 = 'maps/' + data2.name;          // custom usgsoverlay object contains usgs image,         // bounds of image, , reference map.         overlays.push(new usgsoverlay(bounds, srcimage, map));         overlays.push(new usgsoverlay(bounds2, srcimage2, map));

that works fine.

after try add multiple images in loop.

        var overlays = [];         var bounds = [];         var srcimage = [];          usgsoverlay.prototype = new google.maps.overlayview();          (i = 0; < mappings.length; i++) {             var data = mappings[i];               bounds.push(google.maps.latlngbounds(                 new google.maps.latlng(data.latnw, data.lngnw),                 new google.maps.latlng(data.latse, data.lngse)));               // photograph courtesy of u.s. geological survey.             srcimage.push('maps/' + data.name);             // custom usgsoverlay object contains usgs image,             // bounds of image, , reference map.             overlays.push(new usgsoverlay(bounds[i], srcimage[i], map));         }

now can't see image @ map , can't zoom. how can add multiple overlays in loop?

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
