sql – Run batch jobs in Google Cloud Platform

I have an application on App Engine that uses Cloud SQL. There is a table of local events in the database and another table of users and their push notification tokens.

I would like to run a CRON job once a day (preferably within the Google Cloud Platform) to update the local event table with data from an external API and to send push notifications to the users at nearby events that are relevant to their interests are.

Which GCP products do you suggest? I'm currently looking at Cloud Scheduler, but I'm not sure if the batch job should run on App Engine or with another product.

Logic Java algorithm

I have to do this exercise:

7) Make an algorithm that asks 3 numbers and represents the arithmetic mean between these 3 numbers.

Follows my resolution.

package com.Byleo.AreaRetangulo;

import java.util.Scanner;

public class AreaRetangulo {

    public static void main(String() args) {

        @SuppressWarnings("resource")
        Scanner input = new Scanner(System.in);

        double n1, n2, n3, media;

        System.out.println("primeiro n: ");
        n1 = input.nextDouble();

        System.out.println("segundo n: ");
        n2 = input.nextDouble();

        System.out.println("terceiro n: ");
        n3 = input.nextDouble();


        media = (n1 + n2 + n3) / 3;

        System.out.println("Media = " + media);

    }

}

Everything works, my question is as follows:
Could I ask the user a single question and send it to the variables?
I do not know how to do in Java. But in C ++, it would look something like this:

printf("%d%d%d",n1,n2,n3);

typescript – Generic service and implementation service of the Angular Rest API

I wonder if there is a better way to write the ApiService and CategoryService so that CategoryService is basically just a call to ApiService with the string & # 39; category & # 39; and the base type & # 39; ICategory & # 39; to expand, or if this is the best way I can get from typed and angular? There are many more endpoint services in the final app

Any other general comments about code styles, etc. are also welcome (or if anyone knows how to tell Webstorm not to put the constructor's closing parentheses on the next line !!).

ApiService

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs';
import { environment } from '../../environments/environment';

const baseUrl = environment.serverBaseUrl;
const apiEndpoint = environment.apiEndpoint || '/api/v1/';
const apiUrl = `${baseUrl}${apiEndpoint}`;

@Injectable({
  providedIn: 'root'
})
export class ApiService {

  constructor(private http: HttpClient) {
  }

  private createTokenOptions() {
    return {headers: new HttpHeaders().set('Authorization', `Bearer ${localStorage.getItem('access_token')}`)};
  }

  get(serviceEndpoint: string, id?: number): Observable {
    let url = `${apiUrl}${serviceEndpoint}`;
    if (id) {
      url += `/${id}`;
    }
    return this.http.get(url, this.createTokenOptions());
  }

  create(serviceEndpoint, item: T): Observable {
    const options = this.createTokenOptions();
    options.headers = options.headers.append('Content-Type', 'application/json');
    return this.http.post(`${apiUrl}${serviceEndpoint}`, JSON.stringify(item), options);
  }

  delete(serviceEndpoint: string, id: number): Observable {
    return this.http.delete(`${apiUrl}${serviceEndpoint}/${id}`, this.createTokenOptions());
  }
}

Category service

import { Injectable } from '@angular/core';
import { ApiService } from './api.service';
import { Observable } from 'rxjs';
import { ICategory } from '../interfaces/category.model';


@Injectable({
  providedIn: 'root'
})
export class CategoryService {

  private serviceEndpoint = 'category';

  constructor(private api: ApiService) {
  }

  getCategories() {
    return this.api.get(this.serviceEndpoint);
  }

  getCategory(id: number): Observable {
    return this.api.get(this.serviceEndpoint, id);
  }

  createCategory(category: ICategory) {
    return this.api.create(this.serviceEndpoint, category);
  }

  deleteCategory(id: number) {
    return this.api.delete(this.serviceEndpoint, id);
  }
}

8 – Add N rows to a custom Webform composite table

I have a web form with a custom composite element that contains the following fields: article, quantity, order upload, order type, closing date of the text, number, file, selection and date.

Now in hook_form_formid_alter I'm trying to add multiple lines to the compound webform element based on the values ​​of the selection box. but it does not work it returns only a single empty visible element.

I use the following code.

function webform_views_form_webform_submission_ordering_process_add_form_alter(&$form, FormStateInterface $form_state, $form_id) {
  $form('elements')('order_type_')('#ajax') = (
    'callback' => 'update_items',

   $form('elements')('section_type_')('#ajax') = (
    'callback' => 'update_items',

    ),
  ); 
  $section_type = $form_state->getValue('section_type_');
     $order_type = $form_state->getValue('order_type_');
     $items_value = $form_state->getValue('items');
     if($section_type != null && $order_type != null){
         if($section_type == 'Showroom'){
               if($order_type == 'Bought out'){
                $items = array('item1','item2','item3');

legal – How does Airbnb continue to operate legally?

I have never been an Airbnb host, so I do not know what agreements Airbnb has made with the hosts, but I have stayed in many Airbnbs and have observed the following phenomena. Often, my hosts ask me to stay casual on entering the apartment complex or condo (as if I were a regular visitor), and when asked, they should answer me that I stay with my friend (my host).
It seems that they have no legal right to sublet the property and therefore it is illegal to take money to stay with them. How does this go on legitimately under Airbnb?
This definitely hits the local hotel industry.

Although I expect that my hosts have done a dodgy job on these occasions without the announcement of Airbnb, this logically does not allow Airbnb to wash their hands by saying, "It's the host's fault, and we're legal not obliged to take action. "
If something really unpleasant happens to the guests, Airbnb should also share responsibility.
Each such site must have a verification mechanism (which indicates trust in the host).

My question is if Airbnb does not have that, then how is it legitimate?

stock android – contacts are displayed several times with different color codings

Today I switched to a new phone with Android Pie. The model of the phone is Xiaomi Mi A3. I use this option to back up and sync all my contacts in Google Contacts when I switch my phone. This time I came across a problem. Although each contact is saved exactly once in Google Contacts, my Contacts app displays multiple copies of each contact with different color codings. Please suggest a way to solve this. Thanks a lot!Enter image description here
