Keith Brown has published an interesting book (html online) about security for a .NET developer (what key things should a .NET programmer know about Windows security).
The title is "A .NET Developer's Guide to Windows Security" and, after a first and quick reading of some pages, seems very very interesting.
Good work Keith! I need only some free time to read the entire book soon... 
I'm really happy to see that Oracle has joined Microsoft's Visual Studio partner program and that later this year it will release a free software download for Microsoft's Visual Studio .Net 2003 development tools.
This could be an improvement for applications that use Oracle databases and I hope it could be soon translated into a more simple way to interact with Oracle's DB.
This new interest that Oracle seems to have on .NET is really a good thing (but I think that Java will remain their favourite platform to support) !
