Cache-Control with Zend Framework
Today I was optimizing a site that uses heavy PHP and Ajax. I wanted to reduce the amount of data that was being sent from the server. To put this in perspective, if there were no cache hits in a page load there would be a total of 755 KB pulled down over 123 requests.

Gentoo blacklist.py init Script
I have several servers which run an assortment of http, svn, ssh, and ftp services. One of the largest annoyances are automated breaking scripts pounding my services. Recently, I have been looking into blacklist.py: a handy python script written by Reto Glauser, which monitors syslog-ng logs looking for possible break-in attempts. The script uses iptables to block future traffic from suspicious IP’s for a specified amount of time.
After I got the script setup and running I wanted a Gentoo init script that would automatically start the script on boot. After reading through some examples in my /etc/init.d/ directory I seem to have managed to cook up something that works: Read the rest of this entry »
Zend JSON-RPC with Dojo Howto
I have been using the Dojo toolkit as my Javascript library of choice since back in early 2006 when it was still around version 0.4. Since then, the project has made tremendous strides including the release of version 1.0 and 1.1 with 1.2 on the way. At the beginning of 2008 I started using the Zend Framework to build MVC PHP applications and, with the release of 1.5, it has become my PHP framework of choice.
To my delight, the Zend Framework and Dojo have recently announced a partnership which will lead to tighter integration of these two great open source frameworks.
One of the most exciting additions to the Zend Framework is the Zend_Json_Server support for JSON-RPC. I have been using JSON-RPC with Dojo for quite some time and, up until now, it has been challenging to find a design pattern that plays nice with the Model View Controller implementation in the Zend Framework. However, with the addition of the Zend_Json_Server this is no longer the case. Read the rest of this entry »
Adblock Plus, Greasemonkey For Firefox 3 Beta 5
I love Adblock Plus – I refuse to use the internet without it. I also quite enjoy Greasemonkey. Unfortunately, neither is yet compatible with the new Firefox 3b5. I got tired of waiting so I took measures into my own hands.
The XPI file format is basically a glorified zip file, so you can unzip it with a compression utility and modify the maximum version number in install.rdf. Basically I replaced the value in the em:maxVersion field with 3.* so to make it compatible with all versions of Firefox.
Of course, these maximum version numbers are there for a reason: newer versions of Firefox may break the extension functionality, but no problems so far.
For the lazy, I have uploaded the patched install files. Of course I give zero guarantees or warranty for the correct operation of these patched extensions. I encourage you to upgrade to the official compatible version as soon as possible.
To install:
- Download File
- Drag downloaded file into open Firefox window
- Enjoy an Ad-free internet

What Central Authentication Can Do For You
Imagine the following scenario: you are the operator of a small website that has a private user’s area which requires visitors to login to view. A few months later, you want to add a gallery application which also requires users to login and, finally, you want users to be able to edit a community wiki, but not allow non-members to make changes.
We can see that we have two choices: force the users to login to each separate application separately, or somehow combine all the applications under a single login.
