Setting up a wildcard DNS domain on Mac OS X

There are many ways to develop on a Mac, and many stack to choose from. One common and recurring need however is to access your local websites through a named domain, ie using example.dev. Thankfully, there is a really simple way to do this using Dnsmasq as a local resolver.

Install Dnsmasq

This is straightforward with Homebrew:

# Install it
brew install dnsmasq

# Create the etc dir if needed
mkdir -p /usr/local/etc

# Create a simple configuration
# This forces the .dev domain to respond with 127.0.0.1
# You can find more information in the default config file:
#   /usr/local/opt/dnsmasq/dnsmasq.conf.example
echo "address=/.dev/127.0.0.1" > /usr/local/etc/dnsmasq.conf

# Install the daemon startup file
sudo cp -fv /usr/local/opt/dnsmasq/*.plist \
  /Library/LaunchDaemons

# Start the daemon
sudo launchctl load \
  /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist

# Install it

brew install dnsmasq

# Create the etc dir if needed

mkdir -p /usr/local/etc

# Create a simple configuration

# This forces the .dev domain to respond with 127.0.0.1

# You can find more information in the default config file:

# /usr/local/opt/dnsmasq/dnsmasq.conf.example

echo "address=/.dev/127.0.0.1" > /usr/local/etc/dnsmasq.conf

# Install the daemon startup file

sudo cp -fv /usr/local/opt/dnsmasq/*.plist \

/Library/LaunchDaemons

# Start the daemon

sudo launchctl load \

/Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist

Configure Mac OS X

All we need to do is tell the resolver to use Dnsmasq for .dev domains:

# man 5 resolver
sudo mkdir -p /etc/resolver
sudo sh -c 'echo "nameserver 127.0.0.1" > /etc/resolver/dev'

# man 5 resolver

sudo mkdir -p /etc/resolver

sudo sh -c 'echo "nameserver 127.0.0.1" > /etc/resolver/dev'

You can now use any .dev domain and it will always resolve to 127.0.0.1:

ping google.com   # this still works
# PING google.com (74.125.239.38): 56 data bytes

ping foo.dev      # you can use any domain
# PING foo.dev (127.0.0.1): 56 data bytes

ping bar.baz.dev  # or subdomain
# PING foo.dev (127.0.0.1): 56 data bytes

ping google.com # this still works

# PING google.com (74.125.239.38): 56 data bytes

ping foo.dev # you can use any domain

# PING foo.dev (127.0.0.1): 56 data bytes

ping bar.baz.dev # or subdomain

# PING foo.dev (127.0.0.1): 56 data bytes

Conclusion

This is very useful in particular for applications that use subdomains as account identifier: you can easily create new accounts on the fly, and never have to worry about your /etc/hosts file again.

Finally, you may also want to look at Pow (and powder). Pow will automatically start your Rails/Rack applications, and provides a port proxying feature for apps written in other languages. Definitely a great alternative.

That’s it for today.

Cheers!

How To Create Facade On Laravel 5.2

Here is step by step to create facade on laravel 5.2

Create PHP Class File.

Bind that class to Service Provider

Create Class which is this class extends to Illuminate\Support\Facades\Facade

<?php
/**
 * Created by PhpStorm.
 * User: Tuva Ergun
 * Date: 4/29/16
 * Time: 01:03 AM
 */

namespace App\Classes;

class Someclass {
    public function get($data = [])
    {
        echo "foo";
    }
}

<?php

/**

* Created by PhpStorm.

* User: Tuva Ergun

* Date: 4/29/16

* Time: 01:03 AM

namespace App\Classes;

class Someclass {

public function get($data = [])

{

echo "foo";

}

Step 2 – Bind that class to Service Provider

In case i create a new serviceprovider by execute

php artisan make:provider 'SomeclassServiceProvider'

1	php artisan make:provider 'SomeclassServiceProvider'

then add

App::bind('someclass', function()
        {
            return new \App\Classes\Someclass;
        });

App::bind('someclass', function()

{

return new \App\Classes\Someclass;

});

Like so

<?php

namespace App\Providers;

use Illuminate\Support\Facades\App;
use Illuminate\Support\ServiceProvider;

class SomeclassServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        App::bind('someclass', function()
        {
            return new \App\Classes\Someclass;
        });
    }
}

<?php

namespace App\Providers;

use Illuminate\Support\Facades\App;

use Illuminate\Support\ServiceProvider;

class SomeclassServiceProvider extends ServiceProvider

{

/**

* Bootstrap the application services.

* @return void

public function boot()

{

}

/**

* Register the application services.

* @return void

public function register()

{

App::bind('someclass', function()

{

return new \App\Classes\Someclass;

});

}

Step 3 – Register that ServiceProvider to Config\app.php as providers

/*
* Application Service Providers...
*/
App\Providers\SomeclassServiceProvider::class,

* Application Service Providers...

App\Providers\SomeclassServiceProvider::class,

Step 4 – Create Class which is this class extends to Illuminate\Support\Facades\Facade

For Example I create this class in App\Facades\Someclass.php

<?php
/**
 * Created by PhpStorm.
 * User: Tuva Ergun
 * Date: 4/29/16
 * Time: 01:16 PM
 */

namespace App\Facades;
use Illuminate\Support\Facades\Facade;

class Someclas extends Facade{
    protected static function getFacadeAccessor() { return 'someclass'; }
}

<?php

/**

* Created by PhpStorm.

* User: Tuva Ergun

* Date: 4/29/16

* Time: 01:16 PM

namespace App\Facades;

use Illuminate\Support\Facades\Facade;

class Someclas extends Facade{

protected static function getFacadeAccessor() { return 'someclass'; }

}

Step 5 – Register point 4 to Config\app.php as aliases

'Someclass'  => App\Facades\Someclass::class

1	'Someclass' => App\Facades\Someclass::class

Testing
On App\Http\routes.php create single route

Route::get('/', function(){
    Someclass::get();
});

Route::get('/', function(){

Someclass::get();

});

Then check on your browser

PHP strtotime() behavior using days of the week as frames of reference (Windows & Linux)

Say you want to get a set of timestamps so that you can query a database for all records that fall between the start of this week, and the end of this week.

One would logically try something like:

$start_of_week = strtotime("this monday"); // Or "monday this week"
$end_of_week = strtotime("next monday - 1 second"); // Or "monday next week - 1 second"

1 2	$start_of_week = strtotime("this monday"); // Or "monday this week" $end_of_week = strtotime("next monday - 1 second"); // Or "monday next week - 1 second"

That will, in theory, give you a date range of Monday at 00:00:00, and Sunday at 23:59:59. Unforunately, that is not always the case.It turns out trying to find relative time references with strtotime is wonky. Depending on which day it currently is, and what day you’re trying to use as a frame of reference, you will get different results when using ‘this monday’ or ‘tuesday next week’ etc… The results are unintuitive, but more importantly, inconsistent in most cases.

Since strtotime() lets us do lazy math to get timestamps (e.g. ‘this monday – 1 week’), all we need to do is find some date string that works consistently 7 days of the week, and then we can reliably find other timestamps relative to that string. Any date string that does not have the same results for all 7 days, cannot be used as a frame of reference, as its value will change depending on what day it is!

From the tables below, we can see that the following three strings can be safely used as frames of reference in strtotime():

strtotime("next monday");
strtotime("this sunday");
strtotime("last sunday");

strtotime("next monday");

strtotime("this sunday");

strtotime("last sunday");

My suspicion is that certain strings consider Sunday to be the start of the week, while others consider Monday to be the start of the week, and probably round the time up or down in different ways.

Note that I have arbitrarily chosen Monday – March 4th, 2013 through Sunday – March 10th, 2013 as the week to test. Though given how wonky strtotime()’s behavior is, there’s a possibility that the behavior shown below varies from one week to the next! However, I did test various times throughout each day (e.g. 00:00:00 and 23:59:59) and thankfully the results were consistent.

So going back to our problem of getting timestamps for the start and end of this week, the cleanest and most reliable solution is this:

$start_of_week = strtotime("next monday - 1 week"); // Will return Monday of the current week starting at 00:00:00"
$end_of_week = strtotime("next monday - 1 second"); // Will return Sunday of the current week ending at 23:59:59"

1 2	$start_of_week = strtotime("next monday - 1 week"); // Will return Monday of the current week starting at 00:00:00" $end_of_week = strtotime("next monday - 1 second"); // Will return Sunday of the current week ending at 23:59:59"

PHP Trait Kullanımı

PHP 5.4 ile gelen trait PHP’ye multi-inheritance özelliği getirdi. PHP’de 5.4 ten önce sınıflar sadece single-inheritance alabiliyordu. PHP trait bu duruma çok iyi bir çözüm oldu. Daha esnek bir yapı getirdi.

PHP’de trait nasıl kullanılır?
trait bir kendi başına bir sınıf gibidir. Ama bu trait lerden nesneler kuramıyoruz. Sadece yeni sınıflarda genişletebiliyor yeni metodlar ve alanlar ekleyebiliyoruz. Bir sınıfta istediğimiz kadar trait, bir trait ‘ide istediğimiz kadar sınıfın içinde kullanabiliyoruz. Bir sınıf içinde trait kullanmak için use anahtar kelimesini kullanıyoruz. Namespace ile karıştırılmamalıdır.

Örnek bir trait kullanımı

<?php
trait GamePad{
    public function Tuş(){
        echo "X,Y,A,B";
    }
}
trait Kasa{
    public function Rom(){
        return "Rom";
    }
}
class PS3{
    use GamePad, Kasa;
}
$konsol = new PS3;
echo $konsol->Rom();
$konsol->Tuş();
?>

<?php

trait GamePad{

public function Tuş(){

echo "X,Y,A,B";

}

trait Kasa{

public function Rom(){

return "Rom";

}

class PS3{

use GamePad, Kasa;

}

$konsol = new PS3;

echo $konsol->Rom();

$konsol->Tuş();

Çıktı:

Rom
X,Y,A,B

1 2	Rom X,Y,A,B

Yukarıdaki multi-inheritance için basit bir örnekti. Bir çok sınıf bir çok trait için bir örnek yapalım.

<?php
trait GamePad{
    public $_marka = "Sony";
    public function Tuş(){
        echo "X,Y,A,B";
    }
}
trait Kasa{
    public function Rom(){
        return "Rom";
    }
}
class PS3{
    use GamePad, Kasa;
    public function Oyun($oyun){
        echo "PS3 : ".$oyun;
    }
}
 
class Sistem{
    public function Görüntü(){
        return "PAL";
    }
}
 
class XBox extends Sistem{
    use GamePad, Kasa;
    public function Görüntü(){
        return parent::Görüntü() . " Görüntü";
    }
}
$konsol = new PS3;
echo $konsol->Rom();
echo $konsol->_marka;
echo $konsol->Oyun("Fifa 13");
 
$konsol2 = new XBox;
echo $konsol2->Görüntü();
?>

<?php

trait GamePad{

public $_marka = "Sony";

public function Tuş(){

echo "X,Y,A,B";

}

trait Kasa{

public function Rom(){

return "Rom";

}

class PS3{

use GamePad, Kasa;

public function Oyun($oyun){

echo "PS3 : ".$oyun;

}

class Sistem{

public function Görüntü(){

return "PAL";

}

class XBox extends Sistem{

use GamePad, Kasa;

public function Görüntü(){

return parent::Görüntü() . " Görüntü";

}

$konsol = new PS3;

echo $konsol->Rom();

echo $konsol->_marka;

echo $konsol->Oyun("Fifa 13");

$konsol2 = new XBox;

echo $konsol2->Görüntü();

Çıktı:

Rom
Sony
PS3 : Fifa 13
PAL Görüntü

Rom

Sony

PS3 : Fifa 13

PAL Görüntü

PHP – Soyut Sınıflar

Soyut sınıflar içerisinde en az bir soyut metot bulunduran sınıflardır. Genel amaçları bir çok işi ortak yapan ortak sınıfları bir araya toplamaktır. Aşağıda buna uygun bir örnek verilmiştir.

Soyut sınıf denilmesinin sebebi soyut metotların sınıf içerisinde bir görev yapmaması miras yolu(kalıtım) ile kendinden türeyen sınıflara devretmesidir. Soyut sınıflar kendi içlerinde soyut metotlar dışında somut metotlarda bulundurabilir. Bu metotlar ezilmezler(override).

Metotlar ve veri alanları soyut sınıfta protected ve public olarak tanımlanmalıdır ki türeyen sınıfta kullanılabilsin. Sadece soyut sınıfta kullanılan bir veri alanı ise private olarak ta kullanılabilir.

Soyut sınıfta tanımlanmış bir durumda türeyen sınıfta ezilirken(override) erişim türünde kısıtlama yapılamaz. Örneğin; soyut sınıfta public olarak tanımlanan bir alan türetilmiş sınıfta public olmak zorundadır. Soyut sınıfta protected olarak tanımlanan bir alan protected veya public olmak zorundadır. Genişletilebilir ama daraltma yapılamaz.

Bir sınıfın soyut olarak tanımlanması için class deyiminin önüne abstract deyimi getirilir. Soyut sınıfta metotların soyut olarak belirlenmesi için erişim tipinin önüne veya function deyiminin önüne abstract deyimim getirilmeli ve gövdesiz bir metot olmalıdır. Soyut sınıfın hiç soyut metodu yoksa o sınıf soyut metot olarak işlem görmez.

Soyut metotlarda sınıf dışında bir değişkene atama yapılamaz. Yani new ile bir sınıf kurulumu yapılamaz.

Bir örnek verelim.

<?php
abstract class Soyut
{
    protected $toplam_ödeme;
    abstract public function __construct();
    abstract public function Ödeme($miktar);
 
    public function Ödenen() {
        return $this->toplam_ödeme;
    }
}

<?php

abstract class Soyut

{

protected $toplam_ödeme;

abstract public function __construct();

abstract public function Ödeme($miktar);

public function Ödenen() {

return $this->toplam_ödeme;

}

Yukarıda Soyut adında bir soyut sınıf tanımladık. Soyut sınıfımızı extends ile genişletelim. Ortak iş yapan 2 sınıf oluşturalım.

<?php
class Telefon extends Soyut
{
    public function __construct() {
        $this->toplam_ödeme = 10;
    }
    public function Ödeme($ödeme) {
        $this->toplam_ödeme += 1.1 * $ödeme;
    }
    public function ADSL($ödeme) {
        $this->toplam_ödeme += 1.18 * $ödeme;
    }
}
 
class Dogalgaz extends Soyut
{
    public function __construct() {
        $this->toplam_ödeme = 18;
    }
    public function Ödeme($ödeme) {
        $this->toplam_ödeme += 1.2 * $ödeme;
    }
}

<?php

class Telefon extends Soyut

{

public function __construct() {

$this->toplam_ödeme = 10;

}

public function Ödeme($ödeme) {

$this->toplam_ödeme += 1.1 * $ödeme;

}

public function ADSL($ödeme) {

$this->toplam_ödeme += 1.18 * $ödeme;

}

class Dogalgaz extends Soyut

{

public function __construct() {

$this->toplam_ödeme = 18;

}

public function Ödeme($ödeme) {

$this->toplam_ödeme += 1.2 * $ödeme;

}

Yukarıdaki örnekte Soyut sınıfından Telefon ve Dogalgaz isminde 2 tane somut sınıf türettik. Soyut sınıfından kurucuyu(__construct) ve Ödeme fonksiyonlarını eziyor, Ödenen metodunu ise kalıtım ile miras alıyoruz.

Ödenen metodu 2 sınıfta da aynı işi yapmaktadır. Kurucu metot ve Ödeme metodu kendi sınıflarının belirledikleri görevi yerine getirmektedir.

Sınıflarımızı kurup sonuçları görelim.

<?php
$tel = new Telefon();
$tel->Ödeme(50);
echo $tel->Ödenen();
$dgl = new Dogalgaz();
$dgl->Ödeme(50);
echo $dgl->Ödenen();

<?php

$tel = new Telefon();

$tel->Ödeme(50);

echo $tel->Ödenen();

$dgl = new Dogalgaz();

$dgl->Ödeme(50);

echo $dgl->Ödenen();

sonuçlar:

65
78

Aynı parametreleri girmemize rağmen soyut sınıflar sayesinde sonuçlar farklı çıktı.

Google haritalar kullanımı – Gmaps.js

Şirketiniz veya kendiniz için google mapsi kullanarak konumunuzu adresinizi göstermek isteyebilirsiniz ama malesef ki google maps ile bunu yapmak artık zorlaştı bunun için açık kaynak lı bir eklenti yardımıyla istedigimiz işlemleri kolayca yapabiliyoruz..

Peki bunu nasıl kullanıcam?
