Here at my new job we develop in ASP/VB.Net, running off of an SQL Server 2000 (yes, it horrified me too when I found out). The company has been around since ~2000 and we have decided now that it is a time for a change. We are hoping in the next few months to be moving away from a single server based model that we have now, onto something a little more modern, a cloud.
At the same time as we do this, we are wanting to make the move to using OSS. This is going to be quite a move, with our development enivronment being firmly embedded in MS technologies at the moment. So we have a few steps that we are going to be going through. I am hoping over the next few months to share my experiences in moving our product from the MS environment to running on Ubuntu server using Mono (the C# variety) and Postgresql. It will be interesting, with the need for a demonstration of the new product by mid-August.
Also, on a side note, I have moved out of where I was staying temporarily into a new place, and once I have sorted out my internet issues I shall be looking at finally getting around to working on MPLS again.
