As an experiment I have added Subscribe support to AddToAny. The modifications are still ongoing as various bugs are resolved. Due to the number of changes the package is made available as a complete TGZ instead of a very large patch file and numerous additional files.

There were a number of steps required to get "FeedBurner":http://www.feedburner.com to work the way I wanted it to. My goal was a seamless RSS feed that I could easily track using FeedBurner's wonder statistics and maybe get some wider exposure. I also wanted to maintain the "brand", in my case the domain name, as much as possible. Here is what I did: ... Click to read more

On occasion it seems that jQuery and reCAPTCHA are not the best of friends. I encountered a problem on an Drupal 4.7 (with so many changes for performance it is almost a fork) installation using the reCAPTCHA 4.7.x-1.0 and CAPTCHA 4.7.x-1.2 modules. The user login/registration pages use reCAPTCHA and some custom jQuery module for doing rounded corners (single image, liquid layout). This combination caused the page to white-screen as soon as the jQuery modified the DOM. ... Click to read more

Long time ago, in the world of Drupal 4.6 and 4.7 I had a module named L2. This was never hosted at Drupal, as I considered it an experiment and released it via the web site as such. I tried to use the various linking modules available for Drupal 6, but for one reason or another they did not fulfill my needs or made the conversion of my content to difficult. L2 is alive and well and has been improved for Drupal 6. If you were a user of L2 please drop me a note and I will add you to the list of BETA testers.

L2 is a general purpose linking system that acts as an input filter. ... Click to read more

Spent the weekend a bit under the weather so I decided to take a crack at centralized administration to multiple Drupal sites. The task is in internal BETA and the documentation is pre-Alpha (being its incomplete, probably has errors and is otherwise very rough). You can see the notes so far at Drupal configurations. I am pretty pleased with the results, having learned quite a bit about Apache reverse proxies and yet more about some Drupal internals.

Multi-site configurations can be difficult to manage as I discussed in Multiple Drupal sites, one server. One method is to auto log in a user ( as user ID 1, admin) if they came from some secure IP. The theory of operation is pretty straight forward, although my implementation required mod_macro, mod_perl, mod_proxy_html, custom Drupal module and eventually some minor hacks to the core.

The basic idea was to obtain gateway access to any site desired without having to know the admin password. ... Click to read more

Setting up a Multi-Host Drupal site is so easy it is hard for me to justify using the dedicated configuration. Many web pages document this process and these notes are just a quick reference. Again I assume A LAMP stack, modify as needed. The configuration steps are nearly identical and I will cover both types here.

Slight differences between Dedicated, Virtual host and Multi-Host

The configuration steps can be identical for all three! The main difference is how you point Apache to Drupal area. ... Click to read more

I found myself needing to host a number of Drupal sites, all low volume, and having just one system available. Drupal can be configured in the following major ways (there are many others, but these are the common ones): ... Click to read more

1. Dedicated : One site per system (or virtualized system). This is the bets way to isolate Drupal sites but has a number of performance and resource needs not the least is keeping every system updated and tuned.

1. VHOST : Multiple sites per system using Apache virtual named hosts (or IP).
