android - Is it possible to store the return from the Glide library for use with a proxy pattern? -


i'm trying build static method return images activity i've set update programatically display details on given item (hills in scotland). plan include image i'm using glide retrieve google maps. it's possible user flicking between different hills, quite resource , data intensive, hoping use proxy pattern call images when needed, , cache seen persist through app lifecycle.

the code i've written far below, main question kind of object glide returning, , possible store hashmap? use of object placeholder until can find should replace with.

i've read glide caches images automatically, i'm wanting write in code offers placeholder image users no data connection, since it's expected application used remotely. i'm not it's possible check glide's cache specific image, i'd end checking cached image wasn't present, , trying download image poor connection, causing issues user (maybe?) 

private static hashmap<string, object> munroimagemap = new hashmap<string, object>();  public static void getmunroimage(context context, string munroname, double latitude, double longitude, imageview view) {      object imageobject = munroimagemap.get(munroname);      if (imageobject != null){         //view.setimageresource(object);     } else if (imageobject == null /*&& user has data connection*/) {         string googlestreetviewimage =                 "https://maps.googleapis.com/maps/api/streetview?size=600x300&location=" +                         latitude + ","                         + longitude                         + "&heading=151.78&pitch=-0.76&key="                         + context.getstring(r.string.google_services_api_key);          // if possible, i'd put image hashmap before placing view.         glide.with(context).load(googlestreetviewimage).into(view);     } else {         /*view.setimageresource(placeholder image);*/     } }

thanks help! , i'm happy told poor solution if there's better way handle this.

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
