Ce este ACTA

Wed, 04 Apr 2012 05:14:00 -0400

Ce este ACTA:

Ce este de fapt ACTA? ACTA este un acord comercial de combatere a contrafacerii între uniunea europeană și statele membre ale acesteia, australia, canada, japonia, republica coreea, statele unite mexicane, regatul maroc, noua zeelandă, republica singapore, confederația elvețiană și statele unite ale americii.

Cam complicat, nu? Teoretic, ACTA trebuie să îi protejeze pe toti oamenii care produc si distribuie legal Opere, Fonograme, Programe de Calculator, Videograme, etc.Până aici nimic în neregulă aş spune eu… Dar problemele şi mai ales nemulţumirile au apărut atunci când am aflat că ni se încalcă oarecum dreptul la viaţă privată.

Până în acest moment în România nu s-a oficializat nimic in acest sens.

Dar eu stau totuşi si mă gândesc: oare dacă nu ar fi existat suspiciunea (deşi unii spun ca este o certitudine) că ni s-ar încălca dreptul la viată privată, am fi acceptat mai uşor acest acord? Eu cred că nouă de fapt nu ne place că trebuie să plătim licenţe pentru toate programele pe care e avem instalate pe calculatoare şi în nici un caz nu ne place să plătim pentru un CD cu muzică sau un DVD cu un film. “Dar noi nu plătim pentru că nu avem bani, nu pentru că nu ne interesează să fim în legalitate”, nu-i aşa? Sigur că da…. şi dacă vreau să merg la grădina zoologică sar gardul nu trec pe la poartă să cumpăr bilet pentru că nu am destui bani, nu? NU. Pur şi simplu nu mă duc acolo.

Ştiu că nu trăim într-o lume perfectă, dar totuşi cred că cel mai bine ar fi dacă ne-am informa cu privire la lucrurile care ne deranjează şi am decide singuri dacă într-adevăr ne supără atât de tare sau nu.

Am o intrebare pentru toti care “stiu” cum se calculeaza PageRank-ul unei pagini: cum se explica PageRank-ul de 4 al paginii de facebook http://www.facebook.com/zvz.ro in conditiile in care toate link-urile catre ea (pe care le-am gasit noi) sunt cu rel=”nofollow”?

Eu cred ca pentru google, chiar daca nu spune, conteaza si link-urile nofollow; altfel nu se poate explica.

Apropo, cautarea link:http://www.facebook.com/zvz.ro pe Google nu returneaza niciun rezultat.

Importa anunturi in zvz.ro de la parteneri

Wed, 04 Apr 2012 05:07:00 -0400

Echipa zvz.ro iti pune la dispozitie un modul care iti publica anunturile in mod automat pe zvz.ro.

Ajutor si conditii de publicare anunturi gratuite

Ajutor

Adaugarea automata a anunturilor se realizeaza prin descarcarea de catre unul din serverele zvz.ro a unui fisier XML pe care tu il publici pe site-ul tau, la o adresa pe care o comunici echipei zvz.ro. Formatul fisierul xml este similar cu cel generat in aceasta pagina.
Daca nu te intereseaza ca anunturile tale sa aiba specificate judetul, localitatea, pretul sau alte caracteristici, poti sa ne dai si adresa unui flux RSS precum si categoria unde vrei sa-ti fie importate anunturile. Ambele modalitati, prin fisier XML sau prin fisier RSS, se supun conditiilor de mai jos.

Pentru a adauga automat anunturi in zvz.ro, urmeaza urmatorii pasi:

Alege categoria unde vor fi publicate anunturile, din meniul de pe partea stanga a paginii;
Creaza un sablon de anunt, completand caracteristicile care apar dupa selectarea categoriei;
Genereaza codul XML care va fi folosit pe post de sablon;
Analizeaza vizual codul XML, observand ca exista adaugate deja in cod 2 anunturi de test pe baza datelor introduse de tine;
Copiaza codul XML pe serverul tau, la o locatie accesibila de pe internet de catre serverele zvz.ro;
Comunica echipei zvz.ro adresa la care este accesibil fisierul XML (ex: www.serverultau.ro/fisier_cu_anunturi.xml sau www.serverultau.ro/fisier_cu_anunturi.php );

Conditii

Aceste modalitati de publicare automata a anunturilor au urmatoarele limitari/cerinte/conditii:

importul anunturilor este GRATUIT (adica fara bani);
este necesar sa publici un link catre zvz.ro, cu textul anunturi gratuite, pe unul din site-urile tale;
de exemplu:
numarul de anunturi care pot fi publicate pe zi este egal sau mai mic cu pagerank-ul paginii unde ai publicat link-ul catre zvz.ro; deci, daca ai publicat link-ul catre zvz.ro pe un site care are pagerank egal cu 2, atunci se vor publica maxim 2 anunturi pe zi;
anunturile cu acelas ID unic se republica (vor fi ca noi);
anunturile vor avea ca proprietar un utilizator creat in prealabil de catre tine, care va avea specificate datele de contact;

PHP Traits - Properties

Wed, 04 Apr 2012 01:09:39 -0400

Traits can also define properties.

Example #11 Defining Properties

<?php
trait PropertiesTrait {
    public $x = 1;
}

class PropertiesExample {
    use PropertiesTrait;
}

$example = new PropertiesExample;
$example->x;
?>

If a trait defines a property then a class can not define a property with the same name, otherwise an error is issued. It is an E_STRICT if the class definition is compatible (same visibility and initial value) or fatal error otherwise.

Example #12 Conflict Resolution

<?php
trait PropertiesTrait {
    public $same = true;
    public $different = false;
}

class PropertiesExample {
    use PropertiesTrait;
    public $same = true; // Strict Standards
    public $different = true; // Fatal error
}
?>

PHP Traits - Static Trait Members

Wed, 04 Apr 2012 01:09:00 -0400

Static variables can be referred to in trait methods, but cannot be defined by the trait. Traits can, however, define static methods for the exhibiting class.

Example #9 Static Variables

<?php
trait Counter {
    public function inc() {
        static $c = 0;
        $c = $c + 1;
        echo "$c\n";
    }
}

class C1 {
    use Counter;
}

class C2 {
    use Counter;
}

$o = new C1(); $o->inc(); // echo 1
$p = new C2(); $p->inc(); // echo 1
?>

Example #10 Static Methods

<?php
trait StaticExample {
    public static function doSomething() {
        return 'Doing something';
    }
}

class Example {
    use StaticExample;
}

Example::doSomething();
?>

PHP Traits - Abstract Trait Members

Wed, 04 Apr 2012 01:08:18 -0400

Traits support the use of abstract methods in order to impose requirements upon the exhibiting class.

Example #8 Express Requirements by Abstract Methods

<?php
trait Hello {
    public function sayHelloWorld() {
        echo 'Hello'.$this->getWorld();
    }
    abstract public function getWorld();
}

class MyHelloWorld {
    private $world;
    use Hello;
    public function getWorld() {
        return $this->world;
    }
    public function setWorld($val) {
        $this->world = $val;
    }
}
?>

PHP Traits - Traits Composed from Traits

Wed, 04 Apr 2012 01:07:12 -0400

Just as classes can make use of traits, so can other traits. By using one or more traits in a trait definition, it can be composed partially or entirely of the members defined in those other traits.

Example #7 Traits Composed from Traits

<?php
trait Hello {
    public function sayHello() {
        echo 'Hello ';
    }
}

trait World {
    public function sayWorld() {
        echo 'World!';
    }
}

trait HelloWorld {
    use Hello, World;
}

class MyHelloWorld {
    use HelloWorld;
}

$o = new MyHelloWorld();
$o->sayHello();
$o->sayWorld();
?>

Exemplul de mai sus va afișa:

Hello World!

PHP Traits - Changing Method Visibility

Wed, 04 Apr 2012 01:05:46 -0400

Using the as syntax, one can also adjust the visibility of the method in the exhibiting class.

Example #6 Changing Method Visibility

<?php
trait HelloWorld {
    public function sayHello() {
        echo 'Hello World!';
    }
}

// Change visibility of sayHello
class MyClass1 {
    use HelloWorld { sayHello as protected; }
}

// Alias method with changed visibility
// sayHello visibility not changed
class MyClass2 {
    use HelloWorld { sayHello as private myPrivateHello; }
}
?>

PHP Traits - Multiple Traits

Wed, 04 Apr 2012 01:02:08 -0400

Multiple Traits can be inserted into a class by listing them in the use statement, separated by commas.

Example #4 Multiple Traits Usage

<?php
trait Hello {
    public function sayHello() {
        echo 'Hello ';
    }
}

trait World {
    public function sayWorld() {
        echo 'World';
    }
}

class MyHelloWorld {
    use Hello, World;
    public function sayExclamationMark() {
        echo '!';
    }
}

$o = new MyHelloWorld();
$o->sayHello();
$o->sayWorld();
$o->sayExclamationMark();
?>

Exemplul de mai sus va afișa:

Hello World!

PHP Traits - Conflict Resolution

Wed, 04 Apr 2012 01:02:00 -0400

If two Traits insert a method with the same name, a fatal error is produced, if the conflict is not explicitly resolved.

To resolve naming conflicts between Traits used in the same class, the insteadof operator needs to be used to chose exactly one of the conflicting methods.

Since this only allows one to exclude methods, the as operator can be used to allow the inclusion of one of the conflicting methods under another name.

Example #5 Conflict Resolution

In this example, Talker uses the traits A and B. Since A and B have conflicting methods, it defines to use the variant of smallTalk from trait B, and the variant of bigTalk from trait A.

The Aliased_Talker makes use of the as operator to be able to use B’s bigTalk implementation under an additional alias talk.

<?php
trait A {
    public function smallTalk() {
        echo 'a';
    }
    public function bigTalk() {
        echo 'A';
    }
}

trait B {
    public function smallTalk() {
        echo 'b';
    }
    public function bigTalk() {
        echo 'B';
    }
}

class Talker {
    use A, B {
        B::smallTalk insteadof A;
        A::bigTalk insteadof B;
    }
}

class Aliased_Talker {
    use A, B {
        B::smallTalk insteadof A;
        A::bigTalk insteadof B;
        B::bigTalk as talk;
    }
}
?>

PHP Traits - Precedence

Wed, 04 Apr 2012 01:00:00 -0400

Precedence

An inherited member from a base class is overridden by a member inserted by a Trait. The precedence order is that members from the current class override Trait methods, which in return override inherited methods.

Example #2 Precedence Order Example

An inherited method from a base class is overridden by the method inserted into MyHelloWorld from the SayWorld Trait. The behavior is the same for methods defined in the MyHelloWorld class. The precedence order is that methods from the current class override Trait methods, which in turn override methods from the base class.

<?php
class Base {
    public function sayHello() {
        echo 'Hello ';
    }
}

trait SayWorld {
    public function sayHello() {
        parent::sayHello();
        echo 'World!';
    }
}

class MyHelloWorld extends Base {
    use SayWorld;
}

$o = new MyHelloWorld();
$o->sayHello();
?>

Exemplul de mai sus va afișa:

Hello World!

xample #3 Alternate Precedence Order Example

<?php
trait HelloWorld {
    public function sayHello() {
        echo 'Hello World!';
    }
}

class TheWorldIsNotEnough {
    use HelloWorld;
    public function sayHello() {
        echo 'Hello Universe!';
    }
}

$o = new TheWorldIsNotEnough();
$o->sayHello();
?>

Exemplul de mai sus va afișa:

Hello Universe!

Traits

Wed, 04 Apr 2012 00:58:00 -0400

PHP 5.4.0 introduce a new concept TRAITS:

As of PHP 5.4.0, PHP implements a method of code reuse called Traits.

Traits is a mechanism for code reuse in single inheritance languages such as PHP. A Trait is intended to reduce some limitations of single inheritance by enabling a developer to reuse sets of methods freely in several independent classes living in different class hierarchies. The semantics of the combination of Traits and classes is defined in a way which reduces complexity, and avoids the typical problems associated with multiple inheritance and Mixins.

A Trait is similar to a class, but only intended to group functionality in a fine-grained and consistent way. It is not possible to instantiate a Trait on its own. It is an addition to traditional inheritance and enables horizontal composition of behavior; that is, the application of class members without requiring inheritance.

Example #1 Trait example

<?php
trait ezcReflectionReturnInfo {
    function getReturnType() { /*1*/ }
    function getReturnDescription() { /*2*/ }
}

class ezcReflectionMethod extends ReflectionMethod {
    use ezcReflectionReturnInfo;
    /* ... */
}

class ezcReflectionFunction extends ReflectionFunction {
    use ezcReflectionReturnInfo;
    /* ... */
}
?>

PHP migrates to Git

Wed, 04 Apr 2012 00:51:00 -0400

The migration of the PHP source code from Subversion to Git is complete. You can clone or fork the source from our GitHub mirror, and we also now support pull requests made via GitHub. The source is also available via git.php.net, and full instructions on cloning the php-src tree can be found at php.net/git.

One immediate benefit is that future PHP release tags will be signed by the PHP development team. We will be releasing GPG keys for verification purposes in the next few days.

More information on the migration and the new workflow can be found at the Moving to Git FAQ on the PHP Wiki.

Please note that the PHP manual, including translations, continues to be hosted in Subversion for the time being and will be migrated to Git at a later date.

Many thanks to David Soria Parra for his hard work on making the conversion to Git a reality, and to Alexander Moskaliov, Florian Anderiasch and Johannes Schlüter for their work on the scripts required to support the conversion. Let the forking begin!

Antitrust+?

Tue, 03 Apr 2012 15:37:13 -0400

parislemon:

Given my post last night, this will probably sound like piling on. But I’m sorry, it’s the first thing that comes to mind. I don’t see how it can’t.

How on Earth is Google going to avoid antitrust inquiries with their new Search+ features announced today? If Facebook, Twitter, etc, have any decent presence in DC, the ball began rolling a few hours ago.

This is the type of case that Senators die for. Google wrapped it in a bow and placed it in one of their laps.

Most of the broader antitrust concerns against Google are bullshit in my opinion. You can argue that they have a monopoly on search, but it’s a natural one. They’ve earned it. They’re simply better at search than their competitors. This has always been true. It remains true.

But when they use that natural monopoly to start pushing into other verticals, things get gray. Travel, restaurant reviews, etc, etc. We see more of it each year.

ruineshumaines: Busch Gardens welcomed its newest resident...

Tue, 03 Apr 2012 15:32:49 -0400

ruineshumaines:

Busch Gardens welcomed its newest resident earlier this week: an adorable Aardvark born Monday, March 26. The healthy baby weighs about 4.8 pounds and is expected to grow to more than 120 lbs. within its first year.

It is currently living behind the scenes at Jambo Junction – located in the Nairobi area of the park – and is receiving care from members of the animal care team. The baby will join mom “Izzy” and dad “Friz” in the upcoming weeks and will be an Animal Ambassador for the park, along with its older brother “Zawadi,” who will be a year old on April 10.

There are fewer than 40 aardvarks in zoos in North America. They are solitary by nature, and Aardvark births are not common. (via)
