html - How I can mute audio from iframe? -


i'm creating tribute page (for freecodecamp.com) elon musk , wanted include game page via attribute. possible mute autoplay audio? page url: https://codepen.io/auginis/full/bdwbzw/ game: https://blastar-1984.appspot.com/ here code it: 

<iframe src="https://blastar-1984.appspot.com/" width="1000px" height="1000px">   <p>sorry, browser not support game</p> </iframe>

if can use sachin's solution, go it, i'm pretty sure works media elements, audio , video elements, last checked (spec). things change fast, maybe you're in luck.

if can't change @ iframe level, you're going run cross origin issues. if can control headers of app you're embedding, x-frame-origins friend. if use header loosen restrictions on game's original page, javascript need this:

var iframe = document.queryselector('iframe[src="https://blastar-1984.appspot.com/"]');  // code tidied up, depending on how familiar game code  iframe.contentdocument.getelementbyid("muted").checked = true;  iframe.contentwindow.speaker[0].muted = true  iframe.contentwindow.speaker[1].muted = true

if, however, you're not lucky, same origin policy might have beat. in case, i'd suggest making div , replacing iframe when click "play" (excuse lazy css in snippet): example. gives added bonus of not loading content before user wants (which performance / mobile browsers).

good luck!

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
