Rank on Google – 5 high DA 90+ profile backlinks from 5 unique domains for $ 3

Rank on Google – 5 high DA 90+ profile backlinks from 5 unique domains

100% Manually creates 5 profile backlinks on 5 unique DA 90+ websites to improve your SERP position and improve your Google ranking.

Do profiles really work backlinks?

Yes indeed. Profile backlinks can do wonders for a website and improve its Google ranking. If multiple different online profiles refer to specific content on a site, multiple incoming links from different domains will definitely improve the content's authority. Use these backlinks to share valuable links from the Profile Creation website to yours. In addition, online presence on multiple platforms is required to rank higher on Google and other search engines.

Already in 2012, Moz had advised on creating profile backlinks. At the same time, just like other types of backlinks, the mileage can vary in relation to the different factors. Simply put, profile backlinking is very important in today's scenario.

As we all know, search engines like Google use backlinks to calculate the ranking of your website as one of the main metrics. You need High Quality, High DA backlinks if you want to reach a higher rank.

The days when thousands of low-quality spam backlinks were ranked on Google are over, at least for pure Whitehat techniques. While Google and other major search engines achieve higher performance, only high-quality backlinks are now possible.

PR (Page Rank) IS DEAD! Google has stopped updating the PageRank so that the PageRank metrics are no longer displayed. Today, most search engines rely on new metrics based on trust and authority SEO rankings.

laravel – Error in the unique rule during the update

I test the functionality of my request for data validation and encounter the following problem.

If I want to update a record, I have no problem. I have the problem that I want to give the same name to another record. In this case, the error "The name is already registered" should be output. However, instead of returning the error directly, the code explodes.

I enclose my codes to see if anyone has an idea of ​​what might happen.


public function update(SucursalUpdate $request, $id)
    $sucursal = Sucursal::find($id);

    $sucursal->name = $request->name;
    $sucursal->estado = $request->estado;


    return redirect()->route('sucursales.index')->with('info','La sucursal fue actualizada correctamente');

Request BranchUpdate

public function rules()
    return (
        'name'      =>  'required',

Migration Sucursal's Table

public function up()
    Schema::create('sucursals', function (Blueprint $table) {



Forward file

{Route::resource('sucursales', 'AdminSucursalController');
Route::get('sucursales/changeStatus/{id}', 'AdminSucursalController@changeStatus')->name('sucursales.changeStatus');}

Algorithms – How do I check if a flow network contains a unique maximum flow?

I have been facing this problem for a few hours now. My job is to design an efficient (polynomial runtime) algorithm that checks whether or not a given flowchart diagram contains a unique maximum flow. I searched for everything I could and some people said that they are running an algorithm capable of finding a maximum flow first, then changing the edge capacity and running the algorithm again to see if we get the same flux value. However, this never seems to work for me, especially if we get any flow network, such as: B. a non-integer flow graph. How should I start a good approach? (Literally stuck for a few hours)

Unique Artisan Script (Myhammer Clone, Mybuilder Clone, Redbeacon Clone)


We had a craftsman's script for about $ 3,000.
It has many similar features to popular sites like myhammer and mybuilder (reviews, company directories, bids, etc.).
The total cost was $ 3,000. The completion took several months.
We are now trying to sell some licenses to get back part of our investment.
If you are looking for such a system, feel free to contact pm and I will send you a demo link.

The license for a site is $ 250.


feathersjs – Unique field validation with FeatherJS and Joi

With FeatherJS I have defined a user model as follows:

import NeDB from 'nedb';
import path from 'path';
import { Application } from '../declarations';

export default function (app: Application): NeDB {
  const dbPath = app.get('nedb');
  const Model = new NeDB({
    filename: path.join(dbPath, 'users.db'),
    autoload: true,

    fieldName: 'email',
    unique: true,

  return Model;

And I take care of a certain validation thanks to Joi at the user hooks:

import * as feathersAuthentication from '@feathersjs/authentication';
import * as local from '@feathersjs/authentication-local';
import { disallow } from 'feathers-hooks-common';
import Joi from '@hapi/joi';
import { validate } from '../../hooks';

const { authenticate } = feathersAuthentication.hooks;
const { hashPassword, protect } = local.hooks;

const validation = validate(
    email: Joi.string().email().alter({
      create: (schema) => schema.required(),
    password: Joi.string().min(8).alter({
      create: (schema) => schema.required(),

export default {
  before: {
    all: (),
    find: (
    get: (
    create: (
    update: disallow(),
    patch: (
    remove: (

  // ...

Joi validation works and results in an erroneous request error if the submitted data is invalid.

The unique index prevents users from creating an account with an existing email address. However, it will generate a basic 500-error instance that is difficult to exploit in my front app.

Is there a way to do a unique validation with Joi, or should I rethink my logic?

Note: I'm using NeDB here, but moving to Mongo is also possible.
