Art recently promised that there would be an ArcGIS Server Development Blog soon, and now it's there !
Check out our the new blog at http://blogs.esri.com/Dev/blogs/arcgisserver/
You can also find a link to the blog from http://blogs.esri.com
And even better! The server is also running ArcGIS Server.NET, so you can see the examples in action!
From the blog:
This blog is written directly by the ArcGIS Server Development Team. We are very excited about the ArcGIS Server 9.2 release. We have so much to share with the user community. Topics will range from detailed programming information ("What is a page life cycle in the Web ADF?") to GIS methodology ("What is the best methodology to produce map caches?") for serving spatial data with ArcGIS Server. One of the key parts to this blog will be the use of an example site. We intend to post useful entries for our users which are linked directly to examples that we have built that you can access live from the Internet.
Jeremy has already put up a huge post on creating a website with cached tiles and custom tasks, including live running samples you can try.
I just had my first day at ESRI today, where I have joined the ArcGIS Server .NET ADF team.
Everything here seemed well-prepared and set-up when I got there, including a small "seminar" for everyone who started as ESRI today, and ready-installed desktop and laptop computers.
I already got to look "under the hood" of AGS and play around with it - there's definitely some very cool stuff in there! Hopefully I'll get some time to blog some more about it later - or you can have a look at Arts blog as well.
