drupal 6, tagadelic cache clear

Matteo Papadopoulos — Mon, 20 Apr 2009 15:53:47 +0000

I’ve got some problem with the tagadelic module in Drupal 6.x to create tag clouds. Even having removed the “cache” from the site setting, when a new post was published, the clouds didn’t change, never!

At the end I’ve fount a little patch on the web and I’m trying here to explain it to new users, not familiar with patch.

go into the module directory “sites/all/modules/tagadelic” and open the file tagadelic.module with your favourite editor

goto line 215 (or around there) and change the line “

$cache = cache_get($cache_name);" to $cache = cache_get($cache_name, 'cache_block');

goto line 228 and do the same: change

cache_set($cache_name, $tags); to 
cache_set($cache_name, $tags, 'cache_block', CACHE_TEMPORARY);

upload the file and the problem will magically disappear.

PHP convertire apostrofo in apice

Matteo Papadopoulos — Wed, 26 Nov 2008 12:57:12 +0000

Copiando un testo da MS Word in una form capita a volte di imbattersi negli apostrofi di tipo ” ’ ” che difficilmente vengono convertiti correttamente in UTF-8. Questo capita (leggendo un po’ di bug report di php) con alcune versioni di php.

Brutale mna efficace al scelta di convertire tutti questi apostrofi con il singolo apice ‘

$patterns[0] = ‘/[\x82\x91\x92]/’;
$replacements[0] = “‘”;
$txt = preg_replace($patterns, $replacements, “Governatore d’Italia”);

che renderà “Governatore d’Italia”

safari background color differences

It’s quite strange that Safari Browser does render images in a different way from others browsers. I mean: the same .jpg with a black color inside for example, in firefox is shown in the right way, in safari the “black” become a “dark gray”…

safari snapshot

the same in firefox

Well, after a while and many trials I discoverd that the problem is generated by the “profile colors” embedded into jpg saved from photoshop.

You need to save the file again removing the color profiles option:

Configure printer on ubuntu

I’ve got to configure my printer on the new UBUNTU release 8.04; everything was fine, printer on USB detected and so on but, when I’ve got to do the last magic click, the GUI asked me for a localhost password…
Obviously no password was right and I could not finish my setup.
Reading around I’ve found this little trick that might be usefull to someone else:

Alt-F2 to open application launcher and type

gksudo  system-config-printer

Ubuntu will ask your system password and then you’ll be able to configure, delete and modify your printers.
