Disable mouse acceleration on Mac OS X

Note: Don’t touch the mouse settings in Preferences or it will override the above change.

Updating Magento code to be compatible with PHP 5.3

Even tough PHP 5.3 has been out for quite a while, there is still lots of old code out there that will not run correctly when moved from 5.2 to 5.3.

Fix Mantis Captcha Image open_basedir Error

I recently installed the lastest version of Mantis Bug Tracker. Sadly when I tried to signup for the first time, the captcha used in the signup form didn’t show up. Opening the generated jpeg file reveals several errors related to my server’s PHP security settings.

SYSTEM WARNING: ‘file_exists(): open_basedir restriction in effect. File(/usr/share/fonts/corefonts/) is not within the allowed path(s)

mantis/core/utility_api.phpin utility_api.php’ line 253
mantis/core/utility_api.phputility_api.php’ line 255
mantis/core/utility_api.php line 257
mantis/make_captcha_img.php line 124

To fix the problem I added a fonts folder within my Mantis installation root, added the ARIAL.TTF font file inside that folder and then added a $g_system_font_folder variable to the mantis configuration file config_inc.php to point to the fonts folder.
