I've recently had an idea for a jquery plugin that required to show some vector graphics in a browser. In all major browsers you can use SVG for that purpose and in IE we have VML. And it works pretty well too in IE6 and and IE7, but with introduction of Standards Mode in IE8 things got ugly. After half a day of searching, trials and error I was able to come up with a piece of code that enables VML across all necessary IE versions.
As documentation suggest — we should use PEAR to install PHPUnit. Snow Leopard and Lion comes with PEAR preinstalled, but if you try running commands described in PHPUnit manual you wil run into errors because version of PEAR bundled with the system is outdated.
