Calgary, AB – Over 200 information technology professionals and open source enthusiasts are set to descend on the Coast Plaza Hotel in Calgary. The Calgary Open Source Systems Festival (COSSFEST) is a two-day trade show featuring multiple speaking tracks and workshops demonstrating the use of open source software solutions.

In this article, we cover setting up an Active Directory server for use, connecting to it, searching for information, adding, modifying entries, and removing entries. We also examine how to deal with LDAP errors, and get finer control of the results from a search operation. This is followed up by a class definition that encompasses all this functionality into a simple package.

I recently had a project that needed to do a whole lot of number crunching, and then create a PDF to present those numbers and a line chart as well. This presented two problems for me - how to create a PDF from code, and how to create a chart for use within that PDF. I can say that I have had some success and wish to share with you the process. I'll talk about the PDF side of things in this article, and post another soon with details on how I handled the chart. But an overview of the chart solution is included below.

One of the projects I'm working on is to migrate a website from an old/outdated content management system I wrote 5+ years ago to something more modern - Drupal One of the challenges here is the listing type pages that provide rows of links to related websites. These links contain the link title, the URL (of course), and a brief description. The alternatives for moving this data was to either copy the rendered table into a single page node, or make use of the Content Construction Kit (CCK) to create custom nodes reflecting the data. Using CCK allows each list entry to be edited directly and actually follows the intended user's way of thinking much better - they DO NOT know HTML at all.

I noticed some performance problems when I was running two virtual machines simultaneously (a la VMWare Server. When I began looking into this I discovered VMWare was only allowing 1.8 GB of RAM usage for my virtual machines. This struck me as odd because my desktop box was supposed to have 4 GB of RAM. Or so I thought. After some checking I discovered I had been confused with another box, and my desktop did in fact only have 2 GB of RAM. Well now, I had to fix that.

COSSFEST 07 (Calgary Open Source Systems Festival) will bring together professionals, students and enthusiasts who share a common interest in Open Source software. This one-day conference and expo will be made up of speakers and hourly workshops. Booths featuring hardware vendors, software companies, services companies, and (of course) user groups will be on hand. This event is the largest free technology event in Calgary!
