Using a Perl Debugger with Server Side Triggers

Sat, 01 Aug 2009 09:30:00 EDT

This article describes a method to use a perl debugger on trigger scripts without advanced interprocess debugging tools. Using a perl debugger with a V4.x server side trigger launched by the server is very difficult and encounters two known obstacles: The server will fire the trigger and the debugger will run in a thread of the detached server process; the debugger will start but will probably not communicate with you. However, if you manually started the server via a shell command then the perl debugger will start, accept input from the keyboard, then you will loose contact with the debugger; it does not have exclusive access to the keyboard because it is running in the context of the detached server process. The next command you type will go to the shell, not the debugger. It gets messy from there.

Engelbart's Usability Dilemma: Efficiency vs Ease-of-Use

Thu, 10 Apr 2008 09:15:00 EDT

The mouse was the original idea of Doug Engelbart who was the head of the Augmentation Research Center (ARC) at Stanford Research Institute. Engelbart's philosophy is best embodied, in my opinion, in the design of another device that he invented, the five-finger keyboard - with keys like a piano, used by one hand. The problem was, Engelbart's five-finger keyboard and mouse combination was very difficult to learn.

Zend Studio for Eclipse

Thu, 29 Nov 2007 22:00:00 EST

In my many years of programming, almost 20 years now, I have used countless integrated development environments (IDEs). I have used everything from a simple text editor all the way up to the high-end IDEs that Sybase, IBM, and Oracle use. More recently I have come to embrace the open source movement and development in Web environments. My programming language of choice for these days is PHP, so it stands to reason that I would be looking for an IDE. Like so many other developers I followed the path of looking for the pinnacle of IDEs for PHP. I started with basic text editors, moved into text editors with code colorizations, and then into project-based development environments, and finally to a fully robust IDE. The one that I've been using for a few years now is Zend's Studio Professional.
