• Revision 82959 : calcul des scores : on pondère le nombre d’occurence par une fonction ...

  11 juin 2014, par cedric@… — Log

  calcul des scores : on pondère le nombre d’occurence par une fonction inverse a la longueur du contenu (avoir 10 occurences dans un contenu fleuve n’est pas forcément plus pertinent que 2 occurences dans un contenu court)
  Cette modification n’intervient que si pas de fulltext ou si on a activé l’option _FULLTEXT_FIELD_SCORE

  Please help me to solve those errors

• New builds for PHP 5.4 and PHP 5.3

  29 novembre 2012, par Mikko Koppanen — Imagick

  It’s been a while since I last updated this blog (September 2009 to be exact). Time flies ! Anyway, here comes the actual content : updated imagick binaries for PHP 5.3 and PHP 5.4. The download package also includes ImageMagick 6.8.0 binaries compiled with VC9 (Visual Studio 2008). I noticed that the official ImageMagick builds are now Visual Studio 2010 and that wouldn’t work well with PHP compiled with 2008.

  I am not sure if I am violating any license in distributing ImageMagick binaries but if I do, please let me know and I will remove them. The binaries are just stock ImageMagick 6.8.0, which you can download from http://imagemagick.org/.

  In order to get things running you should add the ImageMagick DLL directory into PATH, add the imagick extension to php.ini and things should be running. At least hopefully.

  The download link for the binaries is here : imagick-php54-php53.tgz.
