The websites and services owned by the tech giant – Alphabet giant blacked out for at least one hour on Monday morning. The “Google Down” Hashtag was trending for many hours on Twitter. The fact that billions of individuals and companies around the world rely on these services means a huge percentage of internet users were affected on that day. This blackout started at 6:55 am ET, but Google was able to fix it by 7:52 am ET, and most users across the world were able to use the service thereafter.
The Question we want to try and answer is this: What consequences will this have for the time after the services are restored? How big is the damage that has beed done?
AWS Solutions Architect – Exam Prep
Cloud Engineers and Cloud Architects is one of the most trending job position to date. As many Companies are moving to the Cloud or are expanding their Cloud Infrastructure, your Role as a Cloud Architect becomes critical. This eBook is a summary and preparation for the AWS Solutions Architect Associate Exam. This Course is in development – Pre-Order.
The services and websites that were affected by this outage were YouTube, Google Assistant, Google Docs, Google Drive, Gmail, YouTube, Google classroom, google search engine, and many more. All users that tried to access the system during the time it was down were getting errors. The good news is all these services were restored within an hour and Google apologised to all users that were affected.
What caused this blackout?
According to a statement by Google, they say the outage was due to a fault in their internal systems. The exact cause of the outage was an issue in their automated quota management system, which reduced capacity for Google’s central identity management system, causing it to return errors globally. This meant verification of user requests wasn’t possible, which led to errors on the users’ side.
How much did the Search-Machine Owner lose during this outage?
According to business analysts, the Company lost close to $1.7 million in YouTube Ad revenue alone during the outage on Monday. This value was calculated using the $47,147 that Google earns from YouTube Ad revenue per minute. If all other services that went down are included, the total loss was close to $10 million since YouTube generates about 10% of Google’s revenue.
It’s Cloud Services were affected too – users were not able to log in into their console. This didn’t directly stopped all Google Cloud Services, but it prevented users from accessing the internal Google Cloud Console. What’s more, even if this log-in outage didn’t cause direct harm, the trust has been shattered. The trust in Alphabet to ensure its Cloud Services to be in a position to provide resilient Cloud Services. Monday was a good day – at least for Microsoft Azure and AWS.
This whole GoogleDown incident will most definitely spark many organisations to start the move to a multi-cloud hybrid-cloud solution.
Machine Learning for Stock Trading, Forex Trading, Daytrading or even long-term investing is already here. You can opt to use a fee-based or performance based service and let them manage your money.
If, on the other hand, you are an active investor or trader, you might want to develop your own trading system with your own unique insights. This tutorial will shortly lay out the landscape of such a system. Also, in our On-Demand Course (Machine Learning for Trading) you can learn how to develop such a system on your own.
Data Source / API
First, you need data. Data is key for a machine learning System. Without proper data, nothing else matters. You can get free data from your broker (like Oanda). But with that data your chances to build a profitable system are slim.
It’s therefore advised to make use of paid alternative data. Such data can cost anywhere from 99$ per month to 4999$ per month or even higher. (Example: https://www.quandl.com/alternative-data)
You’ll need to have your own database. For one, you want to save the data you pay for. You also want to save the manipulated data you create (e.g. when you compute the moving average or similar indicators). Also, you need to keep track of your trades, wins, losses, etc.
For this you want to use MySQL or NoSQL (MongoDB) database. If you don’t want to operate and manage a Database yourself, you should take a look at AWS RDS and Goole Cloud SQL Services. They’ll make your life easier in this aspect.
Machine Learning System
This is the actual brain of you system, the one that decides what to do with the incoming chunk of data from your data provider. Do you execute a trade? Do you close a current one? Do you do just nothing?
Your system can be a supervised machine learning model (like a neural net) or it can be an autonomous agent (see: Reinforcement Learning). The latter is gaining momentum in the algorithmic trading scene.
You want to host your system on a performant but most importantly a reliable Computing Machine. Here again, I advise you to use a Cloud Service (AWS EC2, Google Cloud Computer, MS Azure, …).
Before you unleash your system onto your real account, you want backtest it. For this you need your own backtesting system or use a library for that (Example: https://pypi.org/project/backtrader/). Only after a backtest seems to be promising, should you release the system onto your demo account. And only after that onto your real account.
Execute Calls (Buy, Close, Change SL)
This is where the magic hits the real world. You need to keep a close eye on your system. If it fails for a few hours and you don’t notice it, it might leave a short trade that should have been closed. Automatic Alerts are a common thing in the Cloud Service Providers – they’ll even notify you via SMS.
Also, since your System will be running on the servers, without any User Interface, you should think about how you will get a current statement of your account. Maybe you have to build one yourself. Maybe your Broker has one.
It’s 2020 and you want to learn how to create beautiful and modern websites in 2020? This Article will serve as a guide on what you should be looking into, in order to learn to build fast and beautiful websites. We’ll also mention some keyword for technologies with potential, which you can look into.
What is a Website in 2020?
A question that simple shouldn’t be asked in 2020, right? But the lines between Apps, Websites and Software is fading. Here is a good example: certain websites you visit on the phone, you can ‘add to homescreen’. This adds an icon of the website and makes it available even when you offline. (Here is good starting point if you want to learn more about this technology: Progressive Web Apps).
So what is it now? An App or a website? How can you access a website that is offline?
For the sake of simplicity we’ll say that everything is accessed via a browser, is a website. (Except for PDF files, Video files, etc.)
What was Webdesign?
Certain plugins go even a step further and give you finished and multi-functional User Interface Elements (for example a Button). You can read more on such frameworks here: Top 3 UI Frameworks.
So, where you start?
If you are starting your developer journey in 2020, you should feel blessed. You’ll receive advanced programming language and tons and tons of tutorials and cheap (but not always good) courses. Following lines assume that you want to know how to become a Frontend developer.
We’ll also assume that you don’t want to become a Frontend developer just for the sake of becoming of Frontend developer. The motivation behind this is mainly to earn money. Then comes fun and enjoyment. We do not distinguish whether you make money via a wage or freelance work.
In the end it all comes down to fulfilling the demand (for in Frontend development) with your supply of this skill.
Web Dev Basics
Every Website on the these two most basic technologies: HTML5 and CSS.
HTML5 equals to Hyper Text Markup Language 5. It’s the standard markup language for virtually every Website. HTML elements are the most basic elements of an HTML page.
CSSequals to Cascading Style Sheets. CSS takes the UI Elements that were created by HTML and adds some style to them – making our website beautiful and modern.
Modern Websites for Beginners
How to learn it? Well, some people prefer skimming through the docs and learn via trial&error. Others prefer a more focused and directed learning with Courses.

Laravel is a powerful MVC PHP framework. From official docs “Laravel is a web application framework with expressive, elegant syntax”. You must’ve heard about Laravel if you’ve ever worked with PHP. Laravel has experienced major growth since it’s initial release in 2011. Laravel was created by Taylor Otwell. It became the most starred PHP framework on GitHub in 2015.
My goal with this article is to create a guide for those who just want to learn Laravel and explore PHP. This article will not cover every small detail about Laravel but will be enough to get you started with Laravel 6.
You should be familiar with HTML, CSS & most important Object-Oriented programming with PHP 7
A local PHP environment (Valet, Homestead, Vagrant, XAMP, LAMP, etc.)
A database (MySQL, SQLite etc.)
Node & NPM installed and updated
Note: For local environment I’ll be using LAMP (Linux Apache MySQL PHP) as there are no pre-configured environment like Homestead or Valet available for Linux. You can use Homestead for windows or Valet if you’re a Mac user.
I’ll explain how to create a new Laravel 6 application just as I would in real world environment. So let’s get started.
You must plan any project before coding it out. Planning a project before implementation is a major factor in its success. It doesn’t matter how you plan a project. You can plan it on Paper, whiteboard or some simple text file. You can also use Trello for planning out all the components you’re going to create in the project.
Today, we are going to create a Contact Book app. So let’s talk about goals of it.
Display all contacts in a list.
Create a form where people can add new contact.
Validate the form.
Insert the data into the database.
Let’s create a brand-new Laravel project. I like to put all my projects in Development directory. Open your terminal and navigate to this directory.
Next, let’s install Laravel’s command line installer.
composer global require "laravel/installer"
Now, create a new Laravel project.
laravel new ContactBook
This will create a new directory at Development/ContactBook and install a stock Laravel app.
Navigate to newly created directory and run Laravel server by
php artisan serve
You’ll get this output, open your browser and navigate to given address.
Let’s open this newly created project in Editor. You can use any editor or IDE of your choice. My personal favorite IDE for Laravel development is PhpStorm. Now open .env (Environment) file.
Here, you can set different environment variables. You can change the name of the app by editing ‘APP_NAME’. The main part here is ‘DB_*’ variables. You can set different database by specifying driver name. Here you can also set SMTP details.
Setting up Authentication
Laravel made it very easy to enable Login/Registration functionality. In this tutorial, it’s not mandatory to set up authentication, so you can skip this part if you want to.
Laravel’s laravel/ui package provides a quick way to scaffold all the routes and views you need for authentication using a few simple commands:
composer require laravel/ui --dev
php artisan ui bootstrap --auth
npm install && npm run dev
This command will install a layout view, registration and login views, as well as routes for all authentication end-points. A HomeController will also be generated to handle post-login requests to your application’s dashboard.
With the basics set up and working, it’s time to start doing some coding.
Building a Contact List
Building a whole finished project is quite overwhelming, so it’s better if we divide our project in small parts. So let’s start with displaying a list of contacts. It may sound a small task but it still requires a database, table, view and query.
So let’s create a migration. We can create a migration by using Laravel artisan command line tool.
Save it and run the migration by using following command.
php artisan migrate
Now, we’re going to need a model and some dummy data to work with our database. Laravel provides database seeder to populate table with dummy data and a factory class to generate dummy data.
php artisan make:model --factory ContactBook
This command will create a new Contact model. The --factory flag will generate a new factory file. Our newly created factory file will reside in database/factories. Open the ContactFactory.php file and fill the following:
This command will create a new seeder for our contact book table. Open the seeder file by going to database/seeds/ContactBookTableSeeder.php. Now paste the following in it.
public function run()
To activate the following, navigate to database/seeds/DatabaseSeeder.php. Now paste the following in it.
public function run()
Now, run the migration and seed the tables by running the following command.
php artisan migrate:fresh --seed
We have successfully generated fake data for our app! Now we’re ready to create a new view to display a list of Contacts.
Routes & Views
Now it’s time to provide new routes to display a form to add new contact and list existing contacts. We can add new routes to our application in the routes/web.php file.
Here, we can create necessary routes for our app. Laravel provides a default route. To create a new route, we can either use dedicated controller class or closure. For sake of simplicity we’re going to use closure in our app.
Now, let’s update the home route to show all contacts from database table.
This will create a new form with 3 fields, name, phone and description. The form action is ‘/insert’ which we will next. Laravel require to send a csrf token with any type of form submission, so we’ve also included @csrf. This will create a hidden field with a random csrf token.
Navigate to ‘/add’ in your browser, you’ll see something like this.
Handling form submission
Now, with the form is created we can start working on our insert route, to handle the form submission. Open routes file and add the following.
This route is a little complicated than others so let’s walk through it.
First, we are injecting the Illuminate\Http\Request object, which holds the POST data and other data about the request.
Next, we use the request’s validate() method to validate the form data. The validated fields are returned to the $data variable, and we can use them to populate our model.
We require all three fields, and using the pipe character; we can define multiple rules. If validation fails, an exception is thrown, and the route returns the user with the original input data and validation errors.
Next, we use the tap() helper function to create a new ContactBook model instance and then save it. Using tap allows us to call save() and still return the model instance after the save.
Now allow our model to populate given data, we’ve to specify “fillable” properties. Open ContactBook model and add the following.
class ContactBook extends Model
protected $fillable = [
Now, let’s test this in our browser. Navigate to /add and submit the form with proper data.
Congratulations, you’ve created your first Laravel 6 app. This article was designed to get you started on building your app, and you can use this as a building block to gain the skills you need to develop your application.
I hope you liked this article. Subscribe to our mailing list for more articles by me. Have a great day!
What is WordPress? A technical definition is “WordPress is an open source content management system (CRM) built in PHP”. Currently WordPress is the most popular CRM available for free! If you’ve ever used WordPress, you definitely know about themes & plugins in WordPress! In this article I will show you how to create a simple WordPress plugin in less than 15 minutes! But first, let’s talk more about what a plugin actually is.
WordPress plugin is a package of PHP script(s) that can alter your website. A plugin can alter your website in many ways i.e. From adding a simple message in header to creating a whole shop on your website eg. WooCommerce. Plugins can also modify/tweak existing features of your website like changing Login, sending email on specific event etc.
WordPress theme or Plugin?
If you have ever opened a WordPress theme, you’ll know that every theme contains a function.php file. This file contains all the theme related logic and any functionality provided by a particular theme. You can modify this file and add your own custom functionality too. So if we can directly add new feature in function.php, why do we need a plugin? Well the answer is simple, if you only want to add some text in the header or something small like that, you can surely use theme’s function.php. If you want something like a custom chat bot or anything like that, then a plugin would better suit your needs.
The main difference between a theme’s ‘function.php’ and separate plugin is that plugin’s functionality persists regardless of your website’s current theme but any changes from function.php will only be applicable when that particular theme is in use.
Creating our first WordPress Plugin
WordPress plugin’s default structure only requires one PHP file in a separate directory with a PHP block comment containing various data about that plugin. So, to create a plugin you need to navigate to your wp-content/plugins folder. Create a new folder name myFirstPlugin. Inside this new folder create a new file named myfirstplugin.php. Open the created file in any text editor of your choice and paste the following in it.
Plugin Name: My First Plugin
Plugin URI: http://mywebsite.com/
description: My first ever WordPress plugin
Author: Arman Khan
Author URI: https://instagram.com/codingwitharman
Here, only Plugin Name is required, but it’s a good practice to provide as much data as possible about our plugin.
That’s it!! You’ve created your first ever WordPress plugin. You can log in to your wp-admin and go to plugins and active this plugin. Of course, this plugin does not do anything, yet! But it is an active plugin.
How to create a great plugin?
There are some parameters that you should consider while creating your plugin. These parameters will help you create a successful well documented plugin.
How to structure your plugin? Well, this question is quite common among new WordPress developers.
If your plugin provides complex functionality, you should divide it in multiple files. For example, if your plugin has a main class, you should put that in your plugin’s main file and provide connections to other files through it. If your plugin includes UI related files, you should consider sorting them in separate folders like JS/CSS/Images and put all these folders in one assets folder. Well of course this is not a requirement from WordPress but a good plugin structure is always preferred compared to a bad one.
When creating functions in the plugin, you should be very careful naming them. You should never choose more general names for your functions as it might clash with other plugins that have similar functionalities.
The most common solution is to use unique prefix. For example, if your function name is commonFunction then you should replace it with something like ak_commonFunction.
This function runs when a WordPress administrator delete your plugin from backend. This is a great way to remove plugin specific data like tables in database or custom field created by your plugin.
Well, so now you know how to create a simple WordPress plugin. Now you can easily follow articles that require you to create WordPress plugin first. Of course this guide does not contain advance features that a plugin can provide, we’ll cover those topics in future articles for sure. Stay tuned!
