hej, i'm having having problem button should increase number +=1 , display in view number. app.component.ts import { component } '@angular/core'; import { counterservice } '../common/services/counter.service'; @component({ selector: 'app-root', templateurl: './app.component.html', styleurls: ['./app.component.sass'] }) export class appcomponent { constructor(private counterservice: counterservice) {} count() { return this.counterservice } set count(count){ this.counterservice.count += 1; } } counter.service export class counterservice { count = 0; } app.component.html <div class="container"> <div> <p> {{ counterservice.count }}</p> <button (click)="count()" class="btn btn-default form-control increasebtn">increase</button> </div> </div> i can display 0 when i'm stacked incrementation. thx in advance! t

just found strange , interesting lambda behavior. let's have following class: private class task implements runnable { @override public void run() { // process } } the following statement compiling , running: callable task = task::new; could explain why possible ? edit : based on answers below, check following statements: 1. executorservice executor = executors.newsinglethreadexecutor(); executor.submit(task::new); 2. executorservice executor = executors.newsinglethreadexecutor(); executor.submit(new task()); on first glance, seems same, totally different thing. what happens here above situation. the reason executorservice has 2 methods: submit(runnable); submit(callable); so, using code 1. executor process following on it's internal thread: new task() the version 2. call submit(runnable) method , code task.run executed. conclusion: careful lambdas :) the callable not initialized runnable instance, in

i using redis on elasticache node application , today node went down means our app stopped working. took 20 minutes new node provisioned. from reading documentation seems can set cluster automatically promotes slave primary in case of failure. big gotcha seems have set client write primary node , read slave nodes. this means in case of failure, have reconfigure app point newly created 'read' nodes. takes few minutes slave promoted primary. is there no way set if primary fails, slave automatically take on read/write operations? i'm not storing data in redis , low read/write operations, required run app (live video sessions!). if can't have seamless failover in redis, there can use provides functionality? i'm hoping don't have move traditional dbms works need able handle failure well. thanks multi az's should automatically switch on minimal downtime. once have created 1 of these instances, endpoint cluster. amazon point dns entry prope

i looking understand can make code work. learning concept unlock lot in programming understanding. trying count number of times string 'bob' occurs in larger string. here method: s='azcbobobegghakl' in range(len(s)): if (gt[0]+gt[1]+gt[2]) == 'bob': count += 1 gt.replace(gt[0],'') else: gt.replace(gt[0],'') print count how refer string instead of having work integers because of using for in range(len(s)) ? try this: def number_of_occurrences(needle, haystack, overlap=false): hlen, nlen = len(haystack), len(needle) if nlen > hlen: return 0 # no occurrences n, = 0, 0 while < hlen: consecutive_matching_chars = 0 j, ch in enumerate(needle): if (i + j < hlen) , (haystack[i + j] == ch): consecutive_matching_chars += 1 else: break if consecutive_matching_chars == nlen: n += 1

i trying limit fields embedded object in alignak, documentation alignak backend not go detail on how combine 2 functionalities. using alignak_backend_client ( http://alignak-backend-client.readthedocs.io/en/latest/index.html ). right have: params = { "projection": { "name": 1, "ls_last_check": 1, "host":1 }, "embedded": { "host": 1 } } backend = alignak_backend_client.client.backend(alignak_backend_url) backend.login(alignak_admin_userid, alignak_admin_password) backend.get_all("service", params=params) this returns entire host object embedded returned dict, want few fields. looked mogodb serves db alignak , in theory uses dot notation limit returned fields, using: params = { "projection": { "name": 1, "ls_last_check": 1, "host.name":1

i have following code displays normal select list. working fine logically , able log when change happens. problem is, small box being displayed instead of text box adequate show options.and placeholder being displayed normal text. when click on placeholder, values being displayed. import select 'react-select; class selectlist extends component { onchange() { console.log("value changed"); } render() { var select = require('react-select'); var options = [ { value: 'one', label: 'india' }, { value: 'two', label: 'singapore' }, { value: 'three', label: 'iceland' } ]; return( <select name="select list" value="one" options={options} onchange={this.onchange.this(bind}} /> ); } do need css things here.
