javascript - Periodically call node.js function every second -


i have node.js server , client. client has video.js player, progressbar.js , socket.io. want progressbars show buffer percentage of other users.

here piece of server source

function updateprogressbars() {   io.sockets.emit('updateprogressbars'); //send data }  socket.on('userprogressbarupdate',   function(data) {     socket.broadcast.emit('changelocalprogressbar', data); //send data not sender   });

and here client

socket.on('updateprogressbars', function() {   var bufferlevel = myplayer.bufferedpercent();   var data = {     bl: bufferlevel,     n: name   }    socket.emit('userprogressbarupdate', data); //send data server });

changelocalprogressbarlevel changing progressbars on client side dont worry it.

how can make updateprogressbars() called every second.

using setinterval not best choise because should clearinterval. prefer using recursion bluebird promises:

function a() {   if(smthcompleted)     dosmth();   else return promise.delay(1000).then(() => a()); }

this way have better control of code.

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 ...
