How to set visibility of ionic-card? -


in project use native storage 

this.platform.ready().then((readysource) => {       console.log('platform ready from', readysource);       this.nativestorage.getitem('arrivaldetails')         .then(           data =>{             //alert(json.stringify(data.arrivaltime));              this.getflightdetails(data.fligtdetails,data.arrivaltime,data.departuretime);           },             error => console.error(error)          );     });

and want check native storage null or not. if null, want hide ion-card , display text view , if not null want display ion-card , hide text view 

<ion-card">      <ion-card-content>       <p><span>{{fulldetails.departureairportfscode}}</span></p>      </ion-card-content>

you can use additional variable check if empty or not.

let showdata: boolean = false;

and function should looks like

this.platform.ready().then((readysource) => {     console.log('platform ready from', readysource);     this.nativestorage.getitem('arrivaldetails')     .then(data => {         if (data){                             this.showdata = true;             this.getflightdetails(data.fligtdetails,data.arrivaltime,data.departuretime);         }         else              this.showdata = false;     },error => {         console.error(error);          }); });

then in html can use:

<ion-card *ngif="showdata">     <ion-card-content>       <p><span>{{fulldetails.departureairportfscode}}</span></p>     </ion-card-content> </ion-card> <div *ngif="!showdata">    text here </div>

i hope helps.

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
