Welcome back to all our users, let's see what's been happening on DevX at the end of 2009, our inaugural year.

Firstly, some site changes. DevX downloads and forums have been moved to new domains of their own: and This is in preparation for retiring our legacy download and forum sites. Nothing to worry about from a DevX user perspective, the transition is entirely seamless, your DevX identity remains the same across the sites, etc.

October has been the busiest month yet on Developer Exchange, with an array of new content around Cloud Computing, simultaneous with announcements at our Partners 2009 conference. Where to start? Firstly, Mike Riordan introduces the Teradata Express 13.0 family, which is available in Windows and VMware versions.

It was back to school here at the Developer Exchange world domination headquarters, and it was indeed a busy month of September. We rolled out more Viewpoint screencasts, including an overview of portlets and pages, and an excellent introduction to Viewpoint's revolutionary Rewind feature.

We've tweaked the RSS feed mechanism so that it's easier to follow what's going on via your RSS reader. This is probably most useful if you're subscribed to the DevX forums feeds, where there's a lot of activity, and you're particularly interested in viewing that activity through the lens of threading.

It may be summertime and the living easy, and it's true that several regular contributors were spotted sporting conspicuous tans, but August was still a productive month on DevX.

We introduced our first video screencast, an overview of the Filtered Queries portlet in Viewpoint 13.0.1. We intend this to be the first in a ongoing series of screencasts. What prompted this particular screencast is the desire to showcase the power, beauty, and general awesomeness of the latest release of Viewpoint. Michelle Corona gives more detail in the Top 10 New Features of Viewpoint 13.0.1, including spiffy new portlets like Viewpoint Monitoring, SQL Scratchpad, Space Usage and Lock Viewer. Viewpoint's new portlets keep Teradata so far in front of the competition in web-based database management that it's almost cruel.

We launched the Developer Exchange forums earlier this month, and after much pestering from the community, we've now added RSS feeds for the forums. There are feeds for each forum, as well as a combined feed for all forums. Subscribe to the RSS feeds by clicking on the RSS icons for each forum. Coming soon: more email notifications for the forums.

As promised a while back, the Developer Exchange is now hosting Teradata's technical discussion forums. We will eventually be shutting down all the technical forums at the legacy site, so please start posting your topics into the new forums. Note that some of the non-technical forums will continue to be hosted at the previous location. For posting guidelines, a general introduction to the new forums, or to give feedback, please see this forum topic.

 Continuing to make life easier for our contributors and commenters... In addition to RSS feeds, you can now elect to receive email notifications when:

  • a comment is posted on your content (for contributors)
  • there is a follow-up comment in a thread you've commented in

 You can set your preferences via the "Email Notifications" section of My Account.

This blog post introduces a simple global static caching mechanism for PHP. But first, some background. One of the joys of developing this website, the Teradata Developer Exchange, has been building the site on Drupal, a PHP-based Content Management System. Having spent the last decade building heavyweight J2EE apps like Viewpoint, I was curious to see what life was like in the fast-and-loose world of PHP development.

Last week in response, to pestering from our users, we rolled out RSS feeds (see my previous blog post). We're glad to see they're being taken advantage of. However, some users have noted that it was a bit tricky finding the user-specific RSS feeds (no to mention inconsistent UI-wise), especially to find your own RSS feeds.
