amazon web services - Sample javascript browser code for uploading multiple files into AWS S3 -


i have searched topic didn't luck. have tried following: 

$.each(uploadingdata.files, function(key, value) {     file = value;     var params = {         key: 'content-upload-development/' + file.name,         contenttype: file.type,         body: file     };     bucket.upload(params).on('httpuploadprogress', function(evt){         console.log(1);         var percent = parseint((evt.loaded * 100) / evt.total);         var signedformdata = null;         console.log(percent);         $(document).trigger("amazonstatusupdateevent", ["uploading", file.name, percent, signedformdata]);     }).send(function(err, data) {         var signedformdata = {};         console.log('error is: ' + err);         //signedformdata.fileurl = data.location;         signedformdata.filesize = "400m";         $( document ).trigger( "amazonstatusupdateevent", [ "completed", file.name, 100, signedformdata ] );      });     if(counter == 0) {         file = value;     }     counter++; });

but doesn't seem work - not sure why, behaviour seems bit strange. event triggering doesn't seem pop well.

i wondering: using loop call bucket.upload() right approach handle this? or there way of doing this?

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

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
