It looks like ESRI finally put the 9.3 help publicly and you no longer need a password to access it (HT Jithen & Mapperz).

Welcome to ArcGIS Desktop Help 9.3

The ESRI Resource Center is available as well. Unlike the disorganized ArcGIS Support pages, these are focused on the ESRI product you are working with. I’m really happy to see these resource pages, but I’m curious where they fit within the whole ESRI Support and ESRI EDN sites. I suspect that I won’t be using EDN as much as I’ll be using these new resource pages. At any rate the look great and are easy to use; a welcome change from the Support and EDN pages.

UPDATE: It looks like the resource center is still blocked for those who were not in the beta. Someone at ESRI forgot to flip the switch…

There is also a “What’s New in ArcGIS 9.3” Podcast. The direct link to the podcast is here. Why they make it so hard to get to these podcasts are beyond me. Shouldn’t they be available on the resource pages?

Lastly, while I’m getting ready to deploy ArcSDE ArcGIS Server Enterprise with SQL Server 2008, many are very interested in what PostgreSQL brings to the ArcGIS stable at 9.3. Bill Dollins has been working on a couple blog posts about Using ArcSDE 9.3 with PostgreSQL. Just seeing ArcMap push to PostgreSQL and then using uDIG to view the data is powerful. Says Bill:

…depending on how you implement it, ArcSDE for PostgreSQL can provide interoperability between ArcGIS and an open-source stack. uDig can be leveraged in a pinch to edit data loaded into ArcSDE using the PostGIS geometry type, allowing you to expand to meet demand.

I think many organizations will look long and hard at migrating their SQL Server or Oracle implementations to Postgres.
