Checking if a user has a given role in D6

Drupal's API doesn't contain any ready-made function to check if a user has a certain role. While it's certainly easy enough to do, it can take a moment to figure out initially.

Balance Tracker and Maintaining a Community Module

It's been almost a full month since Balance Tracker was released to the Drupal community, and I think it's probably about time to mention it on our website, and try to provide a look into our experience maintaining a community module.

Balance Tracker is a module we wrote to handle user earnings and payouts for a client. The client had a website which paid a commission to users based upon sales, and they needed a way to track how much each user earned in commission, and to track when each user was paid out.

Why we use Drupal

Over the last couple of years, our development approach has shifted considerably. When we originally began doing client work, we regularly used a fairly wide variety of tools (Wordpress, custom apps in PHP, Ruby on Rails, or Java enterprise) in addition to Drupal to accomplish our clients' wide variety of projects.

Search Engine Optimization and Google Ethics

A recent thread at Webmasterworld takes a look at the issue of SEO, Ethics, and Google.
