1. Enable paste plugin.
2. Add handler for parsing inserted text

So your TinyMCE code will look like:

  tinyMCE.init({
        ...
      	plugins: "paste",
      	paste_auto_cleanup_on_paste : true,
      	paste_postprocess : function(pl, o) {
            // remove extra line breaks
            o.node.innerHTML = o.node.innerHTML.replace(/<p.*>\s*(<br>|&nbsp;)\s*<\/p>/ig, "");
        }
  });

      builder: [oxtSluggableTranslit, urlize]

The easiest way I found to transliterate non-ASCII text is to use PECL translit package. For Debian-based systems you can install it with dh-make-php.
Here’s the code:

class oxtSluggableTranslit
{
  /**
   * Convert any passed string to a url friendly string. Converts 'My first blog post' to 'my-first-blog-post'
   *
   * @param  string $text  Text to urlize
   * @return string $text  Urlized text
   */
  static public function urlize($text)
  {
    return Doctrine_Inflector::urlize(transliterate($text, array('cyrillic_transliterate', 'remove_punctuation'), 'utf-8', 'utf-8'));
  }
}

You can view all available transliterate filters by running

php -r 'print_r(transliterate_filters_get());'

Propel::disableInstancePooling();

Propel by default caches in memory all fetched database objects. That means that for scripts with extensive db usage or long running time you may hit php memory_limit sooner or later.
Starting with propel 1.3 shipped with symfony 1.3 and 1.4 which are about to be released you’ll be able to disable instance pooling in database yaml config.

To hide it for newly opened terminal windows by default change this flag in gnome config:
/apps/gnome-terminal/profiles/Default/default_show_menubar to false.

gconftool --type boolean --set /apps/gnome-terminal/profiles/Default/default_show_menubar false

It may be caused by wrong result from mime_content_type() function. To check if it’s your case create simple php script with just one line:

echo mime_content_type('path_to_your_png_image');

If it will give you text/plain then you have three options:

1. Upgrade your PHP to 5.3.0, though I doubt it’s available for most *nix distributions at this time.
2. Install PECL package Fileinfo.
3. The easiest, modify form class.

In first two options sfValidatorFile will use finfo_open function prior to mime_content_type and it should give correct results for PNG image. However, upgrading PHP or installing PECL package isn’t always possible.

The simplest way to fix this bug is to apply small modifications to your form class, just reorder mime type guessers:

public function configure()
{
  $this->validatorSchema['image'] = new sfValidatorFile(array(
      'required'	=> false,
      'path'       => sfConfig::get('sf_upload_dir') . '/directory',
      'mime_types' => 'web_images'
    ));
  $this->validatorSchema['image']->setOption('mime_type_guessers', array(
    array($this->validatorSchema['image'], 'guessFromFileinfo'),
    array($this->validatorSchema['image'], 'guessFromFileBinary'),
    array($this->validatorSchema['image'], 'guessFromMimeContentType')
  ));
}

In this case validator will first try fileinfo (which should be available since PHP 5.3.0), then 'file -bi' which should work correctly on *nix platform and only if both failed it will use mime_content_type

In this post I’ll describe what to do if your phing task requires user input. The solution is simple – ask for user property in ant and pass it back to phing:

<?xml version="1.0" encoding="UTF-8"?>
<project name="project_name">
	<property name="phing.command" value="phing" />
	<target name="task_name" description="Task description">
		<input message="Input property"
			addproperty="property_name" />
		<exec dir="" executable="${phing.command}">
			<arg line="-Dphing_task_property=${property_name}" />
			<arg line="phing_task_name" />
		</exec>
	</target>
</project>

You also need to tell phing not to wait for user input if we’ve passed property via command line. For phing task propertyPrompt use attribute useExistingValue="true".

If your phing property has default value you need to specify this default value in ant input task also.

function yourmodule_menu() {
  $items['http://some.url'] = array(
    'tab_root'	=> 'user',
    'tab_parent'	=> 'user',
    'title' => 'External URL',
    'page callback' => 'user_page',
    'access callback' => 'user_is_anonymous',
    'type' => MENU_LOCAL_TASK,
    'weight'	=> 5
  );
 
  return $items;
}

Change ‘access callback’ to whatever function (or constant) you want, but don’t forget to set ‘page callback’. It is being checked when building menu structure even if we don’t have any page callback actually.

Sometimes it is not enough. I needed two localized version of website but with completely different content – everything including users, admin and super admin. Both version were supposed to run under the same domain and to be distinguished just by locale part in the url. I was too lazy and didn’t want to copy applications or projects (moreover, it is a problem in the future, you’ll have to modify each copy). So, I decided to use different databases with exact schema for different cultures.

Here’s guide how to implement this.

First of all, I need to extract locale parameter from the url. That is easy, you’ll find it in the symfony docs.
Routes config (routing.yml):

action:
  url:   /:locale/:module/:action/*
  requirements: {locale: nl|be}

I needed only NL and BE locales.

Then, you need to setup two databases. I was using symfony 1.1 with doctrine, but it should be possible for 1.2 also and propel or whatever ORM you are convenient with. Doctrine is able to work with multiple connections. However, I don’t need multiple connections. I need them both defined but I need only one current connection for every request. So I’m defining two connections but not specifying any binding to connection in model schema.
Databases config (databases.yml):

all:
  belgium:
    class:          sfDoctrineDatabase
    param:
      dsn:          mysql://user_be:pass_be@host_be/db_be
  primary:
    class:          sfDoctrineDatabase
    param:
      dsn:          mysql://user_nl:pass_nl@host_nl/db_nl

If you check your application at this moment it will use connection last defined.

So, now I only need to switch between these connections. I can do it with filters.
filters.yml:

rendering: ~
security:  ~
l10n:
  class: l10nFilter
cache:     ~
common:    ~
execution: ~

And the filter itself:

class l10nFilter extends sfFilter 
{
  public function execute($filterChain) 
  {
    if ($this->isFirstCall())
    {
      $locale = $this->getContext()->getRequest()->getParameter('locale');
      //sanitize locale
      $this->getContext()->getUser()->setAttribute('locale', $locale);
      $connection = ($locale == 'be') ? 'belgium' : 'primary';
      Doctrine_Manager::getInstance()->setCurrentConnection($connection);
    }
 
    $filterChain->execute();
  }
}

That’s it.

The small issue is that if you are going to use symfony db tasks (e.g. migrations or data population) you’ll need to set additional environments:
databases.yml:

prod_be:
  primary:
    class:          sfDoctrineDatabase
    param:
      dsn:          mysql://user_be:pass_be@host_be/db_be
prod_nl:
  primary:
    class:          sfDoctrineDatabase
    param:
      dsn:          mysql://user_nl:pass_nl@host_nl/db_nl

And call your tasks twice for each pseudo-environment by adding –env=prod_be or –env=prod_nl.

The idea of hierarchical clustering is merging two nearest clusters on every step starting from N one-element clusters. To find two nearest clusters on step K we need (N-K+1)x(N-K+1) matrix of distances between current clusters. We need, in worst case, N times of updating and finding minimum in sequence of NxN, (N-1)x(N-1), (N-2)x(N-2), …, 1×1 matrix. So, in usual realization of HC algorithm it should cost you O(N*N*N) operations.

To improve algorithm complexity up to O(N*N*log(N)) we can use vector V of similar to priority queues structures. V[i] should consist of sorted by distance points P(i,j) where distance is distance between clusters i and j. Our similar to priority queues data structure should support: ability to extract minimal element with complexity O(1), ability to delete element with complexity O(log(n)), and ability to add and element with complexity O(log(n)).

Standard STL priority_queue allows us to extract minimum and add element with required time, but it has no ability to find quickly an element, so we can’t delete elements with complexity O(log(n)). I propose to use set or multiset STL structure instead. Set and multiset uses “red-black tree” data structure with O(log(n)) complexity of deletion and insertion. Also, in STL sets all elements stored in sorted order and we can easily access to minimum (maximum) element [using standard begin() or end() methods].

In my realization I used following structure to store distances and cluster’s indexes:

struct distances
{
	double dist;
	int index;
};

Also I defined appropriate comparing operator so that elements in my set always sorted in right order.

struct Cmp{
	bool operator()(const distances d1, const distances d2) const
	{
		if(d1.dist == d2.dist)
		{
			return d1.index < d2.index;
		}
		return d1.dist < d2.dist;
	}
};

Then declaration of our vector of sets should look like this one:

std::vector> P;

Here is source codes with sample input file and some comments:

#if CV_SSE2
__m128d t = _mm_load_sd( &value );
int i = _mm_cvtsd_si32(t);
return i - _mm_movemask_pd(_mm_cmplt_sd(t,_mm_cvtsi32_sd(t,i)));
#else
....

These errors were related with SSE2. The problem is that my AMD Sempron 2200+ family 6 (x86 family 6 model 8 ) processor do not support SSE2 instructions. SSE – Streaming SIMD Extensions 2 are extends on MMX instructions to operate on special registers to increase computational speed in some cases.

To fix these problems you need to set CV_SSE2 variable to 0 in cxcore’s cxtypes.h (near 65 line).
For example like here:

//  #if defined WIN32 && (!defined WIN64 || defined EM64T) && 
//      (_MSC_VER >= 1400 || defined CV_ICC) 
//      || (defined __SSE2__ && defined __GNUC__ && __GNUC__ >= 4)
//    #include 
//    #define CV_SSE2 1
//  #else
    #define CV_SSE2 0
//  #endif
