javascript - Scroll Event - Seamless Translation Displacement -


adding event listener element scroll event (and wheel too?) i'm trying use displacement (n.scrollleft , n.scrolltop) position element in such way appears not scroll. example, freezing table headers in table when scrolling down stay on top.

i think there fundamental difference between browsers on how scroll event used because in chrome looks good, safari , firefox event seems fire bit late (page scrolls, headers snap shortly after).

seamless on chrome, jittery on safari & firefox:

var container = document.queryselector('#container'); var table = document.queryselector('table'); var topheaders = [].concat.apply([], document.queryselectorall('tbody th'));  container.addeventlistener('scroll', updatetabletranslations, false); container.addeventlistener('wheel', updatetabletranslations, false);  function updatetabletranslations(e){   var x = container.scrollleft;   var y = container.scrolltop;    topheaders.foreach(function (topheader, i) {       topheader.style.transform = translate(0, y);   }); }  function translate(x, y) {   return 'translate(' + x + 'px, ' + y + 'px)'; }

is using scroll displacement right way go this? if so, how can working way like.

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
