Feb 27th

Posted by Twitter in Ross

Attache to volumte that has sparsebundle for your backup.

Go to that directory. cd  \Volumes\mybackup\

hdiutil attach -nomount -readwrite -noautofsck -noverify nameofmybackup.sparsebundle

/dev/disk1              Apple_partition_scheme /dev/disk1s1            Apple_partition_map /dev/disk1s2            Apple_HFSX

The next step was run fsck_hfs on the main volume.

fsck_hfs -rf /dev/disk1s2








If you get "Resource Busy errrors"  Do this.








ps -ax |grep fsck








4437 ??         0:09.33 /System/Library/Filesystems/hfs.fs/Contents/Resources/../../../../../../sbin/fsck_hfs -y /dev/disk1s2




Kill -9 4437

Here are a couple of nifty functions I came across, to limit the results that are returned in a Cake app.


When using the find() function, by default it will return all of the results. These two methods if placed in the appModel will only return results that are associated with a given user.


<?php  
function findMy($type, $options=array()) 
{ 
   if($this->hasField('user_id') && !empty($_SESSION['Auth']['User']['id'])){ 
      $options['conditions'][$this->alias.'.user_id'] = $_SESSION['Auth']['User']['id']; 
      return parent::find($type, $options); 
   } 
   else{ 
      return parent::find($type, $options); 
   } 
} 

function deleteMy($id = null, $cascade = true){ 
   if (!empty($id)) { 
      $this->id = $id; 
   } 
   $id = $this->id; 

   if($this->hasField('user_id') && !empty($_SESSION['Auth']['User']['id'])){ 
      $opt = array( 
         'conditions' => array( 
            $this->alias.'.user_id' => $_SESSION['Auth']['User']['id'], 
            $this->alias.'.id' => $id, 
            ), 
         ); 
      if($this->find('count', $opt) > 0){ 
         return parent::delete($id, $cascade); 
      } 
   } 
   return false 
} 
?>

If you know a little bit about HTML, CSS, and JavaScript you’re already well equipped to create a Safari extension. Since Apple’s documentation can seem intimidating, here’s a tutorial to walk you through creating your first extension, using any custom CSS or JavaScript code you write.

Add this to the model


class Foo extends AppModel {
  var $currentUsrId = NULL;
}



Then add this to the controller


class FooController extends AppController {
 function beforeFilter(){
  parent::beforeFilter();
  $this->Foo->;currentUsrId = $this->;Auth->user('id');
 }
}
