Laravel with Homestead : Web app Development and Management
What is Homestead
-
Homestead is a pre-packaged vagrant box that provides you will all the development tools that you need by default
-
Once you have setup your virtual machine and vagrant, you simply add homestead box to it and all of the development tools are installed automatically for you. This saves you the time of individually installing the required software.
-
Laravel homestead isn’t limited to the Laravel framework.
-
You can generally development any PHP web application using homestead.
Advantages of Homestead
-
Local development environment simulates production environment
-
Needed software out of the box
-
VM’s can be disposable and recreated within minutes without affecting application source code
-
Easily share your vagrantfile with others
Introduction to PHP and Laravel
PHP, very much like node.js or ruby is a back-end language. It is especially suited for web development.
Laravel is a front-end framework for PHP.
Writing PHP and Laravel feels very similar to writing Ruby and Rails respectively.
An example of this can be seen here when we make controllers for websites:
Rails
class ForumsController < ApplicationController
def index
@forums = Forum.all
end
end
Laravel
<?php
class FarmController extends Controller{
public function index(){
$farms = Farm::all();
return view('farms.index', ['farms' => $farms]);
}
}
?>
How to Setup and Install
-
First we needs to install virtual box and vagrant:
and
-
Once these two are installed type the following in your terminal:
vagrant box add laravel/homestead
- You will need to make a choice of what provider you want, enter 2 for virtualbox:
- Next type into your terminal:
git clone https://github.com/laravel/homestead.git Homestead
- To Initialize our homestead we need to cd into the homestead directory and type:
bash init.sh
- Create an ssh key if it doesn’t exist:
ssh-keygen -t rsa -C<EMAIL_ADDRESS>- Open the homestead directory in your preferred text editor, change homestead.yaml to the following::
- In the terminal type:
sudo nano /etc/hosts
- At the end of the file add the following:
<IP_ADDRESS> homestead.app
- Press ctrl + X followed by Y and then enter to save your changes.
Vagrant Global Aliases
# Some shortcuts for easier navigation & access
alias ..="cd ..";
alias vm="ssh<EMAIL_ADDRESS>-p 2222";
# Homestead shortcut
function homestead() {
( cd ~/Homestead && vagrant $* )
}
-
To up vagrant box use: homestead up
-
To stop vagrant box use: homestead halt
-
To log into vagrant box use: homestead ssh
Creating Your First Project
-
Homestead ssh
-
Cd to shared folder ~/Code
-
composer create-project –prefer-dist laravel/laravel Laravel
-
Creates a default project in a directory called Laravel inside of the code folder
-
Laravel uses a MVC architecture
-
To view the created app load homestead.app in the browser, which has been linked to
<IP_ADDRESS>
in the host file
Laravel File Structure
The important files created in the root are:
artisan: It is end point for artisan command which is used for various tasks and functions in Laravel.
composer.json: Dependency and all list for composer installation
.env: This file contain configuration based on the environment of the application.
package.json: This file contain node related dependency, for example compiling SASS or LESS.
Upon installing following directories will be created
- app
- bootstrap
- config
- database
- public
- resources
- routes
- storage
- tests
- vendor
App Directory
App Folder is one of major folder / directory in Laravel Framework, In Laravel Most of logics are written in App folder. This folder / directory contains below folders.
- Console
- Exceptions
- Http
- Controllers
- Middleware
- Providers
Bootstrap Directory
The bootstrap directory of Laravel contains files are used for bootstrapping and configuring Laravel Framework itself. This directory is also contains a cache directory which holds all framework generated files for performance optimization and
- bootstrap
- cache
Config Directory
This directory contains all configration related files of laravel Framework. This directory consist of below files
- app.php
- auth.php
- broadcasting.php
- cache.php
- database.php
- filesystems.php
- mail.php
- queue.php
- services.php
- session.php
- view.php
Database Directory
Laravel’s Database Directory is used to kept your database migrations and seeds. If you are going to use SQLLITE Dtabase, then you can also use this directory to hold and SQLLITE DB.
Public Directory
The public directory of laravel consist of a file named index.php. In Laravel this file is an entry point for your application .This directory also holds your public assets like images , js , css files.
Resources Directory
Laravel’s Resources directory contains all view files of your application. This directory also hold your language files
Routes Directory
The routes directory of laravel contains all of the routes of your applications. web.php, api.php, console.php and channels.php are default routes files that are included in Laravel 5.4
- web.php: - This file contains all routes that RouteServiceProvider places in web middleware group which provides session state, CSRF protection, and cookie encryption.
- api.php: - This file contains all routes that RouteServiceProvider places in the api middleware group, which provides rate limiting.
- console.php: - In this file you may define all of your Closure based console commands.
- channels.php: - In file you may register all of the event broadcasting channels that your application supports
Storage Directory
The storage directory of laravel contains all of your coompiled blade files,sessions files, file caches, and other files generated by the framework.
The storage/app/public is available for storing user-generated files, such as profile image,product images etc
Tests Directory
The tests directory contains all of your automated tests
Vendor Directory
The vendor directory contains Composer dependencies related files of your application.

CrankyCritic® movie reviews: Deep Blue Sea Rated [R], 110 minutes Starring Samuel L. Jackson, Saffron Burrows, Thomas Jane, Michael Rapaport and LL Cool J Screenplay by Duncan Kennedy and Donna Powers & Wayne Powers Directed by Renny Harlin website: http://www.deepbluesea.net
IN SHORT: Smart Sharks. Human sushi. Yum.
As far as investment dollars are concerned, this week's wide release of The Blair Witch Project has got the majors running scared. As far as us folk that pay hard earned dollars for thrills and chills, the better investment (as far as Cranky is concerned) is Renny Harlin's Deep Blue Sea. The e-mail that's come in to Cranky indicates folks either adore or detest Witch, with no evident middle ground. Deep Blue Sea, on the other hand, almost requires an extra large popcorn and soda, so that the greasy golden topping stuff can go splattering all over your date when you applaud at the end of the flick. Even if you don't rave, you won't feel cheated by this top notch popcorn flick.
OK, enough preaching. Let's get down to the nitty gritty chomp chomp.
A lovely moonlit night. Two collegiate couples on a sailboat. Girls in bikinis, men pouring wine and a boombox booming out suitably appropriate music. This night was not made for skinny dipping, or anything else previously filmed 20 years ago in Jaws. This time out, it isn't a case of prehistoric killing machine following genetic programming to lunch on human flesh. This time the mako shark, bred in captivity as part of experiments designed to find a cure for Alzheimer's Disease, has deliberately attacked. How he escaped from captivity at the Aquatica research lab is unknown. What is known is that, when Wall Street hears the story, prime investor Russell Franklin (Samuel L. Jackson) is going to be out $200 million or so. With 48 hours to prove her experiments can keep Franklin out of the poorhouse, Dr. Susan McAlester (Saffron Burrows) pushes her research team to the limit.
One thing you should know about the mako. It's fast. It's intelligent and illegal DNA enhancements as part of the experiments have made it even smarter. You know this from the trailer and commercial. What you don't know, yet, is that there are two generations of mako shark resident at Aquatica. Gen-1 tips the scales at an even ton in a fifteen foot package. Gen-2 adds ten feet and three more tons of mean. They hunt in packs. They can swim backwards. They know where all the security cameras are. Just like any prison inmate, they are biding their time, taking stock of the human sushi on the station: shark expert Carter Blake (Thomas Jane), who likes to swim with the beasts; marine biologists Janice Higgins (Jaqueline McKenzie) and love-of-her-life Jim Whitlock (Stellan Skarsgard); engineer Tom Scoggins (Michael Rapaport) and evangelist cook Sherman "Preacher" Dudley (LL Cool J). Pick your favorite and place your bets on who survives.
The gimmick is great: it isn't man hunting shark on the wide open ocean, which is the classic. It's shark hunting man inside all of the security precautions designed to keep man safe and protected from the elements (until a freak accident and a raging storm break those defenses) and from the power of the genetically bred animals (who are a lot stronger than they look). The effects, a combination of animatronics, real footage and CGI look "real" for the most part. The killing effects occur so quickly that there is little time to react with more than shock. These sharks are so big they can swallow their prey whole, so the gore isn't exploited, much.
On average, a first run movie ticket will run you Eight Bucks. Were Cranky able to set his own price to Deep Blue Sea, he would have paid...
$6.00
Popcorn flick. Pure and simple.

This post is all about Using Github for your project.
Git as we all know is a version controlling system. It keeps a track of your changes and saves it in cloud in github.com or your enterprise domain if using any company/corporate account. This post is to drive you through the usage of most common git commands and their common usage in day to day life.
Installations
MacOS
-
Install Homebrew from https://brew.sh/. Then follow the command to install git in MacOS.
brew install git
Windows
- Install git from Git for Windows.
Linux
- To know if your system is Debian or Red Hat Based System. You can follow this stackexchange url.
Debian Based
Follow the commands to install git in your Debian System.
sudo apt-get update
sudo apt-get upgrade
sudo apt-install git
Red Hat Based
Follow the commands to install git in your Red Hat Based System.
sudo yum upgrade
sudo yum install git
Configurations
The very first thing to do when using git is to setup your email id and name. To do so, follow the below command.
git config --global user.name "John Doe"
git config --global user.email<EMAIL_ADDRESS>You can check these settings git config user.name
or you can check all the config settings and their respective values using git config --list
.
Setting Up SSH Keys
Since github needs to know your identity before any changes goes to github remote repo. Therefore, we have to provide our credentials (username and password) before pushing any changes to remote (this is the version of something that is hosted on a server, most likely GitHub). The alternate way to authenticate yourself is to use ssh key added to your github account. Github’s official documentation is the best place to setup for SSH keys.

Here’s where robots are replacing workers fastest
by Megan Schumann-RutgersRobots are displacing younger, less-educated, and minority workers in the Midwest manufacturing industry at the highest rates, a new report shows.
However, the findings also show that a strong economic recovery over the past decade has saved many jobs and slowed automation in the United States.
The report shows that robots have not yet brought the dire nationwide effects that many have warned about, but the impact of robots varies across groups of workers, regions, and industries.
Estimates of the potential impacts of robots on the US economy vary widely, with some studies predicting that as many as 50% of all workers are at risk of losing their jobs to automation in the coming decades.
The report examines what is happening in practice, estimating the impact of rising automation in the wake of the Great Recession, from 2009 to 2017, a period in which the use of industrial robots in the United States has more than doubled. The Great Recession was the economic downturn from 2007 to 2009 after the US housing collapse and global financial crisis.
Where are robots replacing workers now?
“There have been clear losers with increased automation—namely, younger, less-educated manufacturing workers in the Midwest and younger, minority workers in these industries in particular,” says coauthor William Rodgers, a professor of public policy at Edward J. Bloustein School of Planning and Public Policy and chief economist at the Heldrich Center for Workforce Development at Rutgers University.
“These industries not only have the highest number of robots in use, but are also experiencing the fastest growth in robot adoption.”
Rodgers says the economic recovery of the past decade has masked some of the adverse impacts on the wages and jobs of Midwest manufacturing workers. Absent such a strong recovery, robots would have displaced many more jobs than they did.
The report found that the top 10 areas with the most robot intensity are:
- Los Angeles-Long Beach-Santa Ana, California;
- Chicago-Naperville-Joliet, Illinois;
- Houston-Baytown-Sugar Land, Texas;
- Phoenix-Mesa-Scottsdale, Arizona;
- Detroit-Warren-Dearborn, Michigan;
- Milwaukee-Waukesha-West Allis, Wisconsin;
- Philadelphia-Camden-Wilmington, Pennsylvania-New Jersey-Delaware-Maryland;
- San Jose-Sunnyvale-Santa Clara, California;
- Indianapolis, Indiana;
- Cleveland-Elyria, Ohio.
The researchers mapped out the robot intensity in the 262 most affected metropolitan areas in the US.
Other key findings
- During the Great Recession, robot intensity—the use of robots—plummeted. But since 2009, robot intensity has sharply increased nationwide.
- States in the Midwest (the East North Central, or ENC, census division) consistently have the highest robot intensities, typically at least twice the intensity of all other regions.
- Since 2009, the number of manufacturing robots has more than doubled—from 0.813 per 1,000 workers to 1.974 per 1,000 workers.
- The adoption of robots since the Great Recession has been accompanied by employment gains for some groups of workers, including young, less-educated men and less-educated adult women, and appears not to have affected other groups.
- In Midwest manufacturing industries, robots have sizably decreased wages for young, less-educated men, and women.
The findings suggest that at the current stage and pace of robot growth and with the right economic conditions in place, some workers without a college degree may benefit from robotization.
Rodgers says the experiences of young Midwestern minority and women workers, as well as employers and their communities, can help other parts of the country prepare for and minimize the economic, social, and cultural adjustment costs associated with the introduction and diffusion of robots.
Richard Freeman, a researcher at Harvard University, was the coauthor of the report. The full report is available here, published by the Century Foundation.

trait Read[A] {
def read(s: String): A
}
val fooRead: Read[Foo] = ???
val s: String = ???
val myFoo = fooRead.read(s)
def loadFromFile[A](file: File, aRead: Read[A]): Seq[A]
val foos = loadFromFile(myFile, fooRead)
def seqRead[A](aRead: Read[A]): Read[Seq[A]] = ???
val myFoos = seqRead(fooRead).read(s)
val myComplexFoos: Map[String, Seq[Either[String, Foo]]] =
mapRead(stringRead, seqRead(either(stringRead, fooRead))).read(s)
Give the compiler recipes it can use for certain omitted parameters.
def read[A](a: A)(implicit aRead: Read[A]): A = aRead.read(a)
val myFoo: Foo = read(s)
val myFoo = read[Foo](s) // Alternatively
def loadMixedFile[A, B](file: File)
(implicit aRead: Read[A],
bRead: Read[B]): (Seq[A], Seq[B])
loadMixedFile(someMixedFile)
implicit
keyword.But where do they come from?
An implicit parameter can be a simple value.
implicit val fooRead: Read[Foo] = ???
Or it can be a function that takes additional implicit parameters.
implicit def seqRead[A](implicit aRead: Read[A]): Read[Seq[A]] = ???
This means implicit parameters can compose.
So if you write all this once...
implicit def seqRead[A](implicit aR: Read[A]): Read[Seq[A]] = ???
implicit def mapRead[A, B])(implicit aR: Read[A],
bR: Read[B]): Map[A, B] = ???
implicit def eitherRead[A, B](implicit aR: Read[A],
bR: Read[B]): Either[A, B] = ???
This:
val myComplexFoos: Map[String, Seq[Either[String, Foo]]] =
mapRead(stringRead, seqRead(either(stringRead, fooRead))).read(s)
Becomes this:
val myComplexFoos: Map[String, Seq[Either[String, Foo]]] = read(s)
implicit
keyword.val
s or def
s.def
s can only have implicit parameter lists.Sometimes we have to write the same thing over and over.
val foo = Foo.from(javaFooBeanService.getById(fooId))
/* later */
javaFooBeanService.put(foo.toFooBean)
Provide recipes the compiler can use to fix type errors.
Implicit conversions tell the compiler how to turn something of one type into another.
case class Foo(id: Long, name: String)
// Imagine a FooBean has Java-style accessors.
implicit def toFoo(bean: FooBean): Foo = ???
myFooBean.name // Can invoke Foo methods directly on a FooBean
scalaFooService.put(myFooBean) // Or pass a FooBean where a Foo is expected.
Implicit conversions can also take implicit parameters.
implicit def stringAsFoo(s: String)
(implicit fooRead: Read[Foo]): Foo
val s: String = ???
s.name
scalaFooService.put(s)
implicit
keyword.The compiler will look for an implicit conversion when
Class doesn't have the methods you want? Turn it into one that does.
class ShoutyString(s: String) {
def shouted: String = s.toUpperCase + "!!!"
}
implicit def toShoutyString(s: String): ShoutyString =
new ShoutyString(s)
"okay".shouted // "OKAY!!!"
Implicit classes combine both into one definition.
implicit class ShoutyString(s: String) {
def shouted: String = s.toUpperCase + "!!!"
}
The same rules apply to implicit classes as to implicit conversions.
If your implicit class is stateless, you can (and should) make it a value class. Value classes let you call methods without paying the cost of instantiating them.
implicit class ShoutyString(val s: String) extends AnyVal {
def shouted: String = s.toUpperCase + "!!!"
}
Value classes have one val
constructor parameter and extend AnyVal
.
The compiler checks two basic areas, in order.
(Source: http://docs.scala-lang.org/tutorials/tour/implicit-parameters.html)
Is it in the companion object of the source or target type?
val bar: Bar = foo
val foo: Foo = bar
object Foo {
// If you try to use a Foo like a Bar, this will be found.
implicit def toBar(foo: Foo): Bar = ???
// If you try to use a Bar like a Foo, this will also be found.
implicit def fromBar(bar: Bar): Foo = ???
}
Is it in the companion object of the top-level type?
val n = read[Int](s)
val isP = read[Boolean](s)
object Read {
// Common use case: Declaring instances for standard library
// types.
implicit val readInt: Read[Int] = ???
implicit val readBoolean: Read[Boolean] = ???
}
Is it in the companion object of a type parameter?
val foo = read[Foo](s)
object Foo {
// Common use case: You're using a library that provides Read
// and you want to provide Read instances for your types.
implicit val readFoo: Read[Foo] = ???
}
// Ambiguous!
case class Foo(id: Long)
object Foo {
implicit val readFoo: Read[Foo] = ???
}
trait Read[A] { def read(s: String): A }
object Read {
implicit val readFoo: Read[Foo] = ???
}
read[Foo](s) // Both implicits apply and are in the companion scope
// Ambiguous!
implicit val fooRead1: Read[Foo] = ???
def f() = {
implicit val fooRead2: Read[Foo] = ??
read[Foo](s) // Both implicits apply and are in the first scope
}
// Unambiguous
case class Foo(id: Long)
object Foo {
implicit val readFoo: Read[Foo] = ???
}
implicit val customFooRead: Read[Foo] = ???
read[Foo](s) // Uses customFooRead, which is in the first scope
case class Foo(id: Long)
object Foo {
implicit val readFoo: Read[Foo] = ???
}
import Foo._
trait Read[A] { def read(s: String): A }
object Read {
implicit val readFoo: Read[Foo] = ???
}
// Ambiguous or not?
read[Foo](s)
Use custom, specific types for implicit parameters to avoid ambiguity issues.
Example: You want to define an implicit parameter for a timeout for a database. Defining an implicit Duration would break if you needed to add a different timeout later. Instead, define a DatabaseTimeout case class that wraps a Duration.
Use typeclasses (parameterized implicit parameters like Read[A]) to provide functionality for types that you may or may not control.
Example: play-json provides the Reads and Writes typeclasses so that you can write JSON serializers for any library without requiring that classes inherit from a specific type.
Be conservative with implicit conversions to keep code easy to read even without an IDE.
Example: The standard library provides implicit conversions to and from Java collections. However, it's often more useful for these conversions to be explicit so that you can easily spot which types are Java and which are Scala.
Avoid using implicit classes to add helper methods to integration classes.
Example: Adding implicit extensions to something like a Java database client can seem like a good idea when you start, but it can make testing classes that use the database client more difficult. It's often better to use a non-implicit wrapper trait that you can more easily mock out for testing.
