performance - Concurrent watches in AngularJS app -


currently, developing angularjs application , stuck @ finishing .

in order improve performance of application , reduce memory consumption, thinking limit number of watch on page.

is there recommended limit in angularjs app concurrent watch have best performance of application?

to reduce memory consumption , improve performance idea limit number of watches on page 2,000. utility called ng-stats can track watch count , digest cycles.

jank happens when application cannot keep screen refresh rate. achieve 60 frames-per-second, have 16 milliseconds code execute. crucial scope digest cycles short possible application responsive , smooth. memory use , digest cycle performance directly affected number of active watches. therefore, best keep number of watches below 2,000. open-source utility ng-stats gives developers insight number of watches angular managing, frequency , duration of digest cycles on time.

caution: wary of relying on “single magic metric” golden rule follow. must take context of application account.

the number of watches basic health signal. if have many thousands of watches, or worse, if see number continue grow interact page. strong indications should under hood , review code.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...

angular - DownloadURL return null in below code -

when change file updated in firebase storage when try downloadurl show null. filechange(event: any) { const imagefolder: string = this.employee.id; const filelist: filelist = event.target.files; const file: file = filelist[0]; const storageref = firebase.storage().ref().child(`${imagefolder}/profile.jpg`).put(file); console.log(storageref.snapshot.downloadurl); } the put() asynchronous. if want url after file uploaded have this: firebase.storage().ref().child(`${imagefolder}/profile.jpg`).put(file).then((snapshot) => { storageref = snapshot.downloadurl: console.log(snapshot.downloadurl); });
