I have a lot of developer friends who are still confused about the idea of character sets. The internet is a global phenomena; in today’s world, every developer must understand character sets if they are to create applications that work around the world. Read the rest of this entry »
A few days ago I went and registered the domain dashto.cc and created a really quick-n-dirty URL shortening site. Read the rest of this entry »
One of the first books to be published on the topic of Zend Framework was php|architect’s Guide to Programming with Zend Framework (Amazon). If you’re looking for an “in” into ZF then — eh, well, skip this book. Read the rest of this entry »
I get asked about this a lot. Why did I take the PHP Certification exam? What does it do for me? Was it hard? Read the rest of this entry »
Some of you may know that the last few weeks I’ve been writing an AJAX chat application that plugs in to DeskPRO. One of the problems we ran into is playing sound notifications. The problem is that IE7 likes to pop up a security warning when you use the usual <embed> code. This was unacceptable. So today I just want to briefly talk about how I solved the problem.

I just want to touch on the topic of member visibility (that is, private/protected methods and properties). Read the rest of this entry »
Today I want to cover a kind of security issue that is not addressed very often. Just about any book or article aimed at developers has some warning about XSS and SQL injection. Those two attacks are arguably two of the most harmful, but there are certainly other things to be weary of. In this post I will talk about Cross-Site Request Forgeries or CSRF (“see-surf”).
