I don't know if I'm missing something big, but getting Perl, Apache, PHP, PDO and MySQL to play nice on my Mac OS X 10.5 install on my Intel Core 2 Duo (Penryn) MacBook Pro hasn't been easy. This is partly thanks to Apache being compiled with x86_64 support, and Perl with i386 only.
I just got the regular monthly email from php|architect Magazine informing me that this month's issue is ready to download, and listing all the wonderful things inside. Turns out they went ahead and published the article I wrote for them a couple of months ago.
This article covers the use of the RGB subpixel antialiasing technique used in various software packages including Adobe Reader, Mac OS X's Quartz font rasterizer, XRender, Microsoft ClearType, applied to the improvement of quality of non-text images. It includes a testbed and some sample code in C and PHP.
