android - Glide v4 and Listview -


i have listview custom baseadapter , search toolbar filter list, every time tap on toolbar or put filter (read: every time list refreshed) there flickering due images reloading... how can avoid this?

@override public view getview(final int position, view convertview, viewgroup parent) {     viewholder holder;     if (convertview == null) {         convertview = inflater.inflate(r.layout.listview_row, parent, false);         holder = new viewholder();         holder.flag = (imageview) convertview.findviewbyid(r.id.flag);         holder.name = (textview) convertview.findviewbyid(r.id.name);         holder.place = (textview) convertview.findviewbyid(r.id.place);         convertview.settag(holder);     }     else         holder = (viewholder) convertview.gettag();      holder.name.settext(customlist.get(position).name);     holder.place.settext(customlist.get(position).city + ", " +             customlist.get(position).region + ", " +             customlist.get(position).state);     string url = context.getstring(r.string.main_server) + "flags/" + customlist.get(position).state.tolowercase() + ".png";     glide.with(context).load(url).into(holder.flag);     return convertview; }

save images cache way not fetched again , set again every time apply filter. below code that

apply(requestoptions.diskcachestrategyof(diskcachestrategy.automatic))

note: in glide 4.0.0.

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 ...
