that code work chrome not firefox. firefox, it's tab open , close.

<button id="memberprintreport" type="button"  class="btn btn-primary">imprimer</button>  $("#memberprintreport").on('click', function (e) {    tryit(gethostname() + "/members/" + memberid + "/contract/" + contractid + "/generalcontracts"); }      function tryit(urlserver) {     var win = window.open('_blank');     downloadfile(urlserver, function (blob) {         var url = url.createobjecturl(blob);         win.location = url;     }); }  function downloadfile(url, success) {     var xhr = new xmlhttprequest();     xhr.open('get', url, true);     xhr.setrequestheader("authorization", "basic " + $.cookie('authorization'));     xhr.responsetype = "blob";     xhr.onreadystatechange = function () {         if (xhr.readystate == 4) {             if (success)                 success(xhr.response);         }     };     xhr.send(null); }  function tryit(urlserver) {   downloadfile(urlserver, function (blob) {     var url = url.createobjecturl(blob);      window.open(url, '_blank');    }); }

try updating line 

headers.setcontentdispositionformdata(filename, filename);

to this

headers.setcontentdispositionformdata("inline", filename);

if not work try this:

headers.add("content-disposition", "inline;filename=" + filename)

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
