Criptografia simétrica e assimétrica. Sabe a diferença?

http://pplware.sapo.pt/networking/criptografia-simetrica-e-assimetrica-sabe-a-diferenca/

the difference between include and require in php

The documentation below also applies to require(). The two constructs are identical in every way except how they handle failure. include() produces a Warning while require() results in a Fatal Error.

Remote MySQL Access

GRANT ALL ON *.* TO root@192.168.1.1   IDENTIFIED BY 'palavra-pass'   WITH GRANT OPTION;
FLUSH PRIVILEGES;
We just have to tell Mysql to allow remote logins.
sudo vi /etc/mysql/my.cnf
Out-of-the-box, MySQL only allows connections from the localhost identified by the IP Address of 127.0.0.1.
We need to remove that restriction, so find the line that says
bind-address = 127.0.0.1


netstat -tupan | grep mysql

Recursively delete .svn directories

$ rm -rf 'find . -type d -name .svn'

or

find . -iname ".svn" -print0 | xargs -0 rm -r

Install subversion in ubuntu 10.10

First start off by installing Apache:

sudo apt-get install apache2

Enter the root password and follow the instructions. Check that is it installed correctly by going to http://localhost and checking that you see the standard Apache "It works!" message. Then install subversion and the subversion Apache module:

sudo apt-get install subversion libapache2-svn

Then create a directory to store repositories in:

sudo mkdir /var/svn/
sudo mkdir /var/svn/repositories

and create a test repository:

sudo svnadmin create /var/svn/repositories/test

So that Apache can read and write the repository its user (www-data) needs to be given ownership of it:

sudo chown -R www-data:www-data /var/svn/repositories/test

To be able to authenticate users who access the repository a password file is needed:

sudo htpasswd -c /etc/subversion/passwd paul

Enter a password for the user paul. For additional users repeat the command without the -c option to make sure the existing file is appended to rather than replaced.
Then edit the Apache config file:

sudo gedit /etc/apache2/apache2.conf

Add the following to the end of the file:

#svn users
<Location /svn>
     DAV svn
     SVNParentPath /var/svn/repositories/
     SVNListParentPath On
     AuthType Basic
     AuthName "Test"
     AuthUserFile /etc/subversion/passwd
     <LimitExcept GET PROPFIND OPTIONS REPORT>
        Require valid-user
     </LimitExcept>
  </Location>

 

Save the config file and restart Apache:

sudo /etc/init.d/apache2 restart

The Test repository can now be accessed via

http://localhost/svn/test

PHP The following is an example of a class with a fluent interface implemented in PHP:

class Car {
 private $speed;
 private $color;
 private $doors;
 
 public function setSpeed($speed){
  $this->speed = $speed;
  return $this;
 }
 
 public function setColor($color) {
  $this->color = $color;
  return $this;
 }
 
 public function setDoors($doors) {
  $this->doors = $doors;
  return $this;
 }
}
 
// Fluent interface
$myCar = new Car();
$myCar->setSpeed(100)->setColor('blue')->setDoors(5);
 
// Example without fluent interface
$myCar2 = new Car();
$myCar2->setSpeed(100);
$myCar2->setColor('blue');
$myCar2->setDoors(5);

Don’t steal software, on the street

Don’t steal software, on the street: "

Apparently students from the University of Technology Sydney and Sydney TAFE are more tempted by street-side packaged software than one could possibly imagine. Microsoft Australia catches them in the act. Of course one can’t assume all of them were trying to “steal” software, at the same time that doesn’t make their reactions any less enjoyable.

Anti-theft lunch bags. Here is the description:

...a few spots of mold may work wonders to protect your precious sandwich when your custom labels, pleading requests and desperate detective work fail to find your regular at-work lunch thief. Reusable, resealable, one-size-fits-all and ready to go right out of the box (or brown paper bag), these clever little containers from Think of The might seem more like a prank object or gag toy than a functional product but it will almost certainly deter even the hungriest of would-be food hackers.

For the pointer I thank Lawrence Rothfield, author of this excellent book.
