Working of MVC Model

DB knowledge

Composer and Artisan

A composer is a tool which allows the user to create any project with respect to a given framework. It consists of all the dependencies and libraries.

Artisan is the command-line interface of Laravel. It has a set of commands which will be discussing now in details which helps in building a web application.

Artisan command syntax:

php artisan [ options] [ arguments] Basic Laravel Commands

Some of the basic laravel commands are mentioned below:

1. To list out all the Artisan commands

It starts with giving the syntax of executing the command i.e.

php artisan [command] [options] [arguments]


options: It can be used like –h (for help), -q (for quiet), -v (for version) etc.

commands: It can be used as per command name followed by options and arguments. Few of the commands are migrate, serve, make, help, etc.

This command is used to get help on a particular command name. Let’s say if you would like to know more about the usage and meaning of the command, you can get it by making use of the help utility provided by Artisan.

php artisan help makes:auth


make: auth: It is the command name for which we would like to know more.

php artisan –version

This command will list out the version of the Laravel framework which you are using.

php artisan down

This command is used to put the laravel application under maintenance mode.

php artisan up

This command is used to bring back the laravel application up and running.

This laravel command will clear all the compiled view files.

php artisan route: list

This command will list all the registered routes.

php artisan route: clear

This command will clear all the route cache file.

php artisan route: cache

This command creates a route cache file for faster route registration

Intermediate Laravel Commands

Some of those kinds of requiring intermediate laravel commands are mentioned below:

php artisan serve

This command is used to start a laravel project, and by default, the application will be hosted at localhost with port number 8000

php artisan make: model EduCBA

Guide To Different Types Of Spoofing

Introduction to Spoofing

Web development, programming languages, Software testing & others

Different Types of Spoofing

Let us discuss the various types of Spoofing.

Email Spoofing

When an attacker uses a fake email address to execute a cyberattack, this is known as email spoofing. The attacker may impersonate the email address, the email sender name, or both, depending on the email spoofing technique. Furthermore, the attacker can adopt various identities, including that of the sender, the company, or sometimes both.

The sender’s name, for example, is [email protected], although Jon Stark is not employed by ABC Textiles. Jon is not a real person, but the recipient works at ABC Textiles, a huge multinational corporation. Because the email has the logo of the company and urges her to perform legitimate work-related duties, the recipient trusts it. The spoofed email, as phishing, uses urgent and compelling language to entice the recipient to take action right away. This sense of urgency accomplishes two goals: it reduces the risk of uncertainty and doubt, and it persuades the recipient that they are assisting and doing the right thing.

Caller ID Spoofing

Caller ID spoofing is a common technique in which contact information that appears to originate from your area code is used. When we notice it’s a local number, we’re more likely to receive the phone. Because the caller appears to be from a police officer, the target is forced to pay bogus fines, reveal personal information, and so on, all under the threat of being arrested.

Website Spoofing GPS Spoofing IP Addresses Spoofing

IP address spoofing is commonly used to execute a denial-of-service attack, flooding the network with traffic and eventually shutting it down. In other cases, the cybercriminal just wishes to conceal their location from the recipient; this strategy might be used with email or website spoofing to give the attack more validity.

Text Message Spoofing

The use of a fake phone number to send harmful text messages is known as text messaging spoofing. The attacker hides behind the sender name or phone number. This sort of spoofing relies on extensive research to determine which types of text messages the recipient is most likely to receive and respond to. The text message could contain a phone or mobile number for the recipient to contact or a link to a harmful website that can be used to commit more cybercrime. To get the recipient to respond promptly, the SMS message uses social engineering techniques.

Address Resolution Protocol or ARP spoofing DNS Spoofing

Doman Name Server spoofing, often known as DNS spoofing, allows attackers to divert traffic from a real IP address to a fake IP address. This spoofing technique could be used by attackers to send people to malicious websites.

Extension Spoofing Facial spoofing

Facial spoofing is a new type of spoofing that uses facial recognition software for unlocking or gaining access to a secure structure. This method of spoofing is very rare, but as facial recognition technology progresses and more companies adopt it as part of their security system, the possibilities of facial spoofing will increase.


Spoofing is sometimes easy to notice, but not always—malicious attackers are increasingly executing complex spoofing attacks that demand user attentiveness. Knowing the different types of spoofing and how to spot them can help you avoid becoming a victim.

20 Helpful Google Home Commands To Try

Google Home, the diminutive smart speaker powered by the Google Assistant bot, wants to invade your living room. But once you’ve plugged it in and connected it up to your Wi-Fi, how do you use it? We’re here to help.

In terms of what it can do, Google Home still lags behind Amazon’s Alexa devices, such as the Echo. That’s particularly true when it comes to third-party plug-ins from your favorite pizza store or audiobook app. Nevertheless, the smart speaker can take care of a lot of tasks. To put it through its paces, try out the commands below.

1. Look up travel times

“OK Google, how far is it from LA to San Francisco?” “OK Google, how long does it take to walk from Santa Monica to Hollywood?”

Google Home knows its directions, as you would expect with Google Maps working away behind the scenes. You can question it about distances (which are usually based on driving), or ask it how long a journey will take with a specific mode of transport.

2. Find great places nearby

“OK Google, what restaurants are nearby?” “OK Google, what are the best bars in New York?”

Speaking of location-based queries, you can look up nearby venues, get Google’s recommendations about places to go, and learn the travel times to those places. It doesn’t work quite as well as a query on the Google Maps website, but it’s handy to have in a pinch.

3. Find answers from the web

“OK Google, how many days until Christmas?” “OK Google, what is the capital of Norway?”

Pretty much anything you can type into the Google search engine is going to work on Google Home, particularly more basic web queries that have a simple, short answer. The speaker pulls information from Wikipedia and various other online sources.

4. Listen to music and radio

“OK Google, play Fleet Foxes.” “OK Google, play a dance mix.”

Google Home doesn’t use Bluetooth, but you can cast audio to it from any app that supports casting (which is a lot of them). Alternatively, ask to hear music from Spotify or Google Play Music directly—you can set the default player in the Google Home app.

5. Check your schedule

“OK Google, what am I doing next week?” “OK Google, when’s my next appointment?”

Google Home plugs straight into your Google Calendar (at the moment, no other calendars are supported), so you can ask about what you’ve got coming up, when you’re supposed to be in a meeting, and various other questions about your schedule.

6. Review the day ahead

“OK Google, tell me about my day.” “OK Google, how’s the weather?”

Ask Google about your day, and you’ll get a weather forecast, a few snippets from your calendar, and some brief news updates. You can configure all of this in the Google Home app. Alternatively, just ask about the weather, either today or at some point in the future.

7. Learn a new language

“OK Google, translate ‘beer’ into French.” “OK Google, translate ‘where is the train station?’ into German.”

It’s easy to forget just how many apps and services Google has, and here’s another: Google Translate. Google Home will make foreign visitors feel welcome, or just help you with your pronunciation. It’s one of those features that makes Google’s AI feel almost like magic.

8. Get math help

“OK Google, what is eight miles in kilometers?” “OK Google, what is 100 dollars in euros?”

Google Home can work out conversions between units just as easily as the Google search engine. Test it with distances, lengths, temperatures, and more. The smart speaker can also perform basic calculations, and even flip a coin or roll a die for you.

9. Play voice games

“OK Google, play a game.” “OK Google, play Lucky Trivia.”

Google Home comes with a selection of basic games you can play with your voice, including Lucky Trivia and Crystal Ball. The former gives you a selection of trivia questions and can be played with friends; the latter essentially acts like a comedy Magic 8 ball.

10. Set alarms and timers

“OK Google, set an alarm for 7 AM.” “OK Google, set a timer for two minutes.”

Want to adjust the time you wake up in the morning? Google Home can handle it without breaking a sweat. Head to the app if you need to view, edit, or delete any timers and alarms you’ve set, or if you need to adjust the alarm volume—the default version is pretty loud.

Use Google Home with your TV David Nield/Popular Science

11. Tweak your shopping list

“OK Google, add milk to my shopping list.” “OK Google, what’s on my shopping list?”

Google gladly adds and removes items to and from your shopping list for you. Voice commands let you request this service, and you can also have the speaker read your list out loud. If you’d like to avoid bringing a smart speaker to the grocery store, you can also access the up-to-date list through your Google Home app.

12. Browse the dictionary

“OK Google, spell ‘onomatopoeia.’” “OK Google, what does ‘meteoric’ mean?”

Whether you’re stuck for the definition of a word or need to win a spelling argument, just ask Google Home. Again, it taps into the pooled knowledge of the internet to pull out an answer for you. You can also ask “what’s another word for…” to hear a list of synonyms.

13. Watch videos on TV

“OK Google, watch House of Cards from Netflix on my TV.” “OK Google, watch YouTube on my TV.”

Got a Chromecast? Through the streaming device, you can ask your Google Home to beam videos straight to the TV (though the request needs to be something easily understood as a voice command). This trick works with Netflix too, if you link your account to the Google Home app.

14. Play music on TV

“OK Google, play R.E.M. on my TV.” “OK Google, play relaxing music on my TV.”

The same trick goes for sending music to your Chromecast. As long as you say the magic words “on my TV” at the end, whatever you ask for gets sent to the big screen. As with playing tunes on the Google Home speaker itself, you can set your default music player in the app.

15. View your photos on TV

“OK Google, show photos on my TV.” “OK Google, show photos from Sydney on my TV.”

For another Chromecast trick, you can display your photos on a much bigger screen. (Currently, Google Photos is the only supported photo service.) You can get creative with the pictures you want to see, thanks to the smart technology inside Google Photos. Try asking to see specific dates or places or people, and see what your television displays.

Close to Home Google

16. Stay up to date on sports

“OK Google, who are the Denver Broncos playing next?” “OK Google, what was the LA Lakers score?”

Google Home is able to look up sports scores, fixtures, and results for you. Over time, it can even learn your favorite teams. If you head into the News section of the Google Home app, you can add a localized sports section to your daily briefing as well.

17. Learn about movie details

“OK Google, who won Best Picture?” “OK Google, who’s in Beauty and the Beast?”

Google Home seems to be a movie fan. The speaker can provide information about movie casts, running times, awards, and so on. What it can’t do, at the time of writing, is tell you what movies are showing nearby. But Google will almost certainly add this feature in the near future.

18. Check on flights

“Is my flight on time?” “How much are flights to New York?”

Over time, Google Home will probably add more personalized data from Gmail and your other accounts. For now, you can check up on flights, whether that’s getting details about an existing trip (this only works if the information is in an email) or researching future trips based on destination or flight number.

19. Control your smart home

“OK Google, turn off my lights.” “OK Google, raise the temperature one degree.”

Right now, Google Home doesn’t have as many third-party plug-ins as the Amazon Echo—but they’re growing in number all the time. If you’ve got Philips Hue lights or a Nest thermostat, you can control them via Google Home voice commands. For more information, check out our beginners’ guide to smart homes.

20. Hear poems and jokes

“OK Google, read me a poem.” “OK Google, tell me a joke.”

One area where Google Home particularly impresses is in the smaller, less obvious touches, such as the ability to read short poems or tell jokes. The smart speaker also contains a few easter eggs—for example, try asking Google Home, “Where’s Waldo?” or “What are the three laws of robotics?”.

How Does Laravel Permissions Work With Examples

Introduction to Laravel Permissions

Laravel is one of the most sought after frameworks for E-commerce development. The reason for this popularity being the ease of usage. Laravel allows the developer of the scope of creating complex structures and functionalities using simple and expressive syntax. Laravel is scalable and that is the reason why E-commerce site owners prefer to use it. This gives them a wide range of options to choose from for catering to demanding customers. Laravel is known for its vast library of queries which provide all that is needed for quick development. The framework is also capable of integrating with third-party queries to form standalone systems.

Web development, programming languages, Software testing & others

One such query that makes development easy is Laravel Permissions.

What is Laravel Permission? How does Laravel Permission work?

Through Roles and Permissions, one can create several types of users with different roles and permissions, some users will only have view access, some users can also edit items, some can go ahead and delete. Access is usually provided by the Super Admin.

Example #1

Installing the tool: The migration needs to be run: PHP artisan migrate

1. The HasRole needs to be added to the User Model:

class User extends Authenticatable { use HasRoles; ... }

2. It now has to be loaded into the Tool for the Roles to be displayed:

public function tools() /* defining the function tools */ { return [ new NovaToolPermissions(), ]; }

3. Adding an additional relationship if roles are to be assigned from the User resource:

public function fields(Request $request) { return [ ... BelongsToMany::make('Role', 'role', Role::class), ]; }

4. Since we are using the Nova Tool for permission, the viewNova Gate default can be replaced with Gate():

protected function gate() { }

5. This program comes with default permissions:

"viewNova": "viewRoles": "manageRoles": "assignRoles": "viewUsers": "manageUsers":

6. It is pertinent to know that, routine permission is required for certain sections. This is to ascertain that only the correct authority has access to the sections of the blog or the whole blog.

For example, the policy related to the blog: PHP artisan make: policy BlogPolicy Now the policy needs to be assigned:

class AuthServiceProvider extends ServiceProvider { use ValidatesPermissions; protected $policies = [ ]; public function boot() { collect([ 'viewBlog', 'manageBlog', Gate::define($permission, function ($user) use ($permission) { return true; } }); }); } }

7. Final step. Access control has to be specified in the policy:

use IlluminateSupportFacadesGate; public function viewAny($user) { return Gate::any(['viewBlog', 'manageBlog'], $user); } public function view($user, $post) { return Gate::any(['viewBlog', 'manageBlog'], $user, $post); } public function create($user) { } public function update($user, $post) { } public function delete($user, $post) { } public function restore($user, $post) { } public function forceDelete($user, $post) { }

8. Now add labels:

{ "viewBlog": "View Blog", "manageBlog": "Manage Blog" }


This one is for the Edit Role:

The Role would now need to be assigned.

Example #2

Another quick example:

Install: Install it into the Laravel application which uses Nova through composer. Register the provider in case you have the package discovery disabled. It will be registered in the config/app PHP file as shown below:

NovaPermissionServiceProvider::class, ]

1. Now tool needs to be registered as shown below:

/*defining tools method */ public function tools() { return [ /*…*/ LaravelNovaPermission::make(), ]; }

2. Now, the addition of Morph To Many to the resource as follows:

use LaravelNovaFieldMorphToMany; /*defining method*/ public function field(Request $request) { return [ /* ...*/ MorphToMany::make('Role', 'role', Role::class), MorphToMany::make('Permission', 'permission', Permission::class), ]; }

3. Now, adding class ForgetCachedPermissions to the config/nova.php as follows:

/* config/nova.php */ /*Registering middleware*/ ‘web’, /*adding different classes*/ DispatchServingNovaEvent::class, Authenticate::class, Authorize::class, BootTools::class, ForgetCachedPermissions::class, ],

4. Artisan command line can be used for localization files publishing: vendor: publish. Usage of Custom Role:

/*app/Providers/NovaServiceProvider.php*/ /*defining tools method */ public function tools() { return [ /* ...*/ LaravelNovaPermission::make() ]; }

5. Changing the default Authorization (Policy-based) to Permissions based Authorisation:

/* app/Nova/MyNovaResource.php*/ class MyNovaResource extends Resource { use PermissionsBasedAuthTrait; /* defining array*/ public static $permissionsForAbilities = [ ]; } public static $permissionsForAbilities = [ ];


Here one can create Roles and give access to users as well as to others who would have defined Roles. It is imperative to remember that at the top of the Access control Hierarchy, sits the Super Admin. The Role of the Super Admin is to provide definite access control authorizations for specific responsibilities. Developers need to be careful while creating ACL or Access Control Lists, since a wrong move here may lead to jeopardizing the entire project.

Steps to Provide Laravel Permissions

Another way to provide permissions is:

Step #1

PHP artisan make: seeder PermissionSeeder

Step #2 <?PHP use IlluminateDatabaseSeeder; use SpatiePermissionModelsRole; use SpatiePermissionModelsPermission; class PermissionSeeder extends Seeder { /** * Run the database seeds. * @return void */ public function run() { $roles=[ 'admin', 'accountant', 'user' ]; $permissions=[ ]; foreach ($roles as $role) { } foreach ($authorized_roles as $role) { } } } }

Add role to the Users

Go ahead and refresh the database:

php artisan migrate: fresh –seed


Laravel Permission is important from the perspective of access control. An access control list is a concise set of information authorising users for a certain level of access. Laravel Permissions work on the basis of hierarchy. Developers will be given a higher level of access than front end users.

The administrator of the site will be provided with greater access. The final access rests with the Super Admin. He/she will be the one providing everyone with the Roles and their access limits.

How To Run Bash Commands In The Background In Linux

There’s nothing more annoying than running a command in your terminal and having it run for minutes, sometimes hours, and not be able to use your terminal again. Sure, you can use tabs, but that’s a clunky solution, and it’s not always optimal because you may want to see updates as you’re working. Here we show you a few different ways to run bash commands in the background in Linux.

End a Command with &

If you want to push a command into the background, using & at the end is an easy way to do that. This way, you can issue a command in the background and continue to use your terminal as it runs. It comes with a catch, though. Using & doesn’t disconnect the command away from you; it just pushes it into the background. This means that while you’re trying to use the terminal, anything the command wants to push to STDOUT or STDERR will still be printed, which may be distracting.



When the terminal session is closed, the command ends. You can also kill the command by issuing the jobs command, finding the number of the command that’s running, and killing it with the kill command. That syntax is as follows:




Using & is good if you need to push something off for a bit but don’t expect it to continue forever.

& After a Command, Then Disown It

Running a command with just & pushes it off to the back and keeps it running as long as the terminal window is open. If, however, you’re looking to keep this command running in constant, even with your terminal session ending, you can use the disown command.

To use this method, start by adding an &.



As mentioned above, using & pushes this command into the background but doesn’t detach it from your user. You can verify this by typing jobs into the terminal. It’ll show the command running in the background as we saw before.

Just type disown into the shell, and it’ll do just that. (And you can once again verify this with the jobs command.)

You can just make out the disown command in there

Now you can close your terminal and continue about your day. It’ll still keep piping things to STDOUT or STDERR, but once you exit and reopen your terminal, you won’t see anything there. You can find the command again with the top or ps commands and kill it with the kill command.

The disowned job is the second one, with the PID 16238.

& After a Command with /dev/null

Adding & after a command will push a command into the background, but as a result, the background command will continue to print messages into the terminal as you’re using it. If you’re looking to prevent this, consider redirecting the command to /dev/null.

Nohup, with & and /dev/null

Unlike the previous commands, using nohup allows you to run a command in the background and keep it running. How? nohup bypasses the HUP signal (signal hang up), making it possible to run commands in the background even when the terminal is off. Combine this command with redirection to “/dev/null” (to prevent nohup from making a chúng tôi file), and everything goes to the background with one command.

Still, some programs on Linux lack the ability to run as a daemon or integrate with modern init systems. This is a real inconvenience but is understandable, as not all developers have the skill or time to add new features.

Luckily, commands like nohup or disown are still a reality and can close the gap in moving programs like this to the background. They’re not perfect or fancy, but they get the job done when needed.

How To Use Cloudera Cdh With Different Steps?

Introduction to Cloudera CDH

Cloudera CDH is Cloudera’s 100% open-source platform distribution provided by Cloudera Inc; it is a Palo Alto-based American Enterprise Software Company that includes Apache Hadoop, built to meet enterprise demands. Cloudera CDH delivers everything a user needs specifically for enterprise use. CDH, Cloudera Distributed Hadoop, provides the most complete, tested, and popular distribution of Apache Hadoop and other related projects. It delivers core elements of Hadoop, distributed computing, scalable storage, vital enterprise capabilities, and Web User Interface. We will explore how to use Cloudera CDH, establish its connection to Cloud Storage, and set it up.

Start Your Free Data Science Course

Hadoop, Data Science, Statistics & others

How to Use Cloudera CDH?

Step 1: Before installing Cloudera Manager CDH and other managed services, the user needs to take care of Storage Space and plan for Cloudera Manager.

Cloudera Manager needs to track job metrics and applications in background processes. Storage requirements can vary depending on the organization’s size, and it can be either local, remote, or disk-based, as all the metrics require storage.

Failing to plan the storage needs, CDH can negatively impact in many ways –

A cluster might miss critical audit information not retained or gathered for the required time.

A cluster might not be able to get the historical operational data to meet internal requirements.

Gaps might be present in collections and charts.

Administrators may not have historical Yarn, MR1, or Impala data usage when they need to reference or report on it later.

Administrators may be unable to have the research health status or past data.

Configuration host in Clusters allows all the members to communicate with each other.

Setting the unique hostname

Editing /etc/hosts/ with IP address and qualified Domain name for each host in the cluster.

Editing /etc/sysconfig/network with Domain name of the host.

Verifying each host consistently identifies a network.

Firewall disabling, save the existing rule set for iptables, and then disable the firewall based on the compatibility, be it RHEL 7 and SLES or Ubuntu.

Setting Secured Enhanced Linux allows for setting the control access through policies. For example, if there is an issue in Deploying CDH, then SELinux should be set in permissive mode on every host before deploying CDH on a cluster.

Enabling NTP Service: Cloudera CDH needs Network Time Protocol(NTP) configuration on each machine in the cluster. And have the Software Collection Library Repository installed in the system.

Step 2: Connection of Cloudera Manager to Cloud Storage/ Setup Connectivity of CDH

Configuring Repository for Cloudera Manager. You install Cloudera Manager using a package tool such as zypper for SLES, yum for RHEL, and apt-get for Ubuntu.

Install JDK, Java Development Kit. It can be either Oracle JDK by Cloudera using the Cloudera Manager or an Open JDK. Most of the Linux distributions that Cloudera supports include Open JDK.

Based on the Operating system, the syntax for installing packages is as below:

sudo yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server        à Oracle Linux, CentOS, RHEL

sudo zypper install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server       à SLES

sudo apt-get install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server       à Ubuntu

Installation and Configuration of Database. Cloudera uses various databases and datastore to store information about Cloudera’s configuration and the system’s health or task. Users can use MariaDB, PostgreSQL, Oracle DB, or MySQL for Cloudera Server and other services.

Setting up the Cloudera Database, Cloudera Server includes a script that helps to create and configure the database. First, the script can create a Cloudera Server Database config file. Then, create a database for the Cloudera server for usage and create and configure a user account for Cloudera Server.

After setting up the Cloudera database, you must start the Cloudera Manager Server and log in to the Admin console to install CDH and other related software. The default credentials would be admin, and the password is also admin by default.

Setting up Cluster using Wizard, after completion of adding the clusters, the installation wizard, Add Cluster Configuration Wizard, will automatically start.

Getting Started with Cloudera CDH

Cloudera CDH provides –

Compatibility: It leverages IT infrastructure and investment.

Flexibility: It stores any data and manipulates it with various computation frameworks that include batch processing, free text search, interactive SQL, statistical computation, and machine learning.

High Availability: It performs mission-critical business tasks with utmost confidence.

Scalability: It enables various applications that scale and extend to suit user requirements.

Security: It processes and controls sensitive data.

Cloudera CDH – Classic Clusters

Classic clusters track the total number of clusters enabled for Replication Manager, track clusters in error state, active clusters, and clusters for which a warning has been issued.

Users must register on existing on-premise Cloudera Distribution of Hadoop on the Management Console, after which users can copy or move the data to the cloud. These are called classic clusters.

Classic Clusters show below statuses –

Active, Warning, Error, Total.

You must use Cloudera Manager for CDH to investigate the classic cluster’s status.


With this, we shall conclude the topic “Cloudera CDH.” We have seen what CDH is and how it is used, and how it is to be installed; the steps required to install and prerequisites before installation have also been looked into. We have also gone through Cloudera Connectivity to Cloud Storage or the setup of Cloudera CDH. Finally, I have gone through the Classic clusters in Cloudera CDH, which will help to give a deeper insight into the concept.
